It is less clear that patients with conditions associated with protein loss purchase 750 mg cipro mastercard, such as nephrotic syndrome and protein-losing enteropathy cheap cipro 1000mg overnight delivery, benefit from extra protein intake buy discount cipro 250mg. If energy requirements are met or exceeded purchase cipro 500mg free shipping, studies have shown that well-nourished adults can maintain nitrogen balance when given as little as 0. In order to allow for biologic variability, the standard recommendation for protein intake is 0. It is important that the protein supplied be of high quality; it should include all essential amino acids and a balanced mix of nonessential amino acids. Malnourished, septic, injured or burned patients will require more protein, in the order of 1. It is not clear that patients with conditions associated with protein loss, such as protein-losing enteropathy, benefit from extra protein intake. Indeed, patients with nephrotic syndrome may even benefit from protein restriction, though this is not firmly established. The Harris-Benedict equation may be less accurate in malnourished or obese individuals. Malnourished patients exhibit resting energy requirements about 10% to 20% below predicted. The resting energy requirements of obese patients will also be below predicted since adipose tissue is less metabolically active than other tissues. In overweight patients, it has been proposed that an adjusted weight be used in the Harris-Benedict equation based on actual and ideal body weight, using the following formula: Adjusted weight = [(actual body wt - ideal wt) 0. Joer (also called Mifflin) formula may be a better choice for calculating resting energy expenditure in the obese patient. The population of subjects upon which the formula is based needs to be understood. Types of Nutritional Intervention The options for refeeding include oral refeeding, tube feeding and total parenteral nutrition. An assessment by a dietitian regarding current food intake and food preferences is essential. It may well be possible by determining food preferences to provide a well-balanced, nutritionally First Principles of Gastroenterology and Hepatology A. In addition, supplements of high-calorie, high-protein foods such as milkshakes or commercially prepared liquid formula diets may allow for adequate intake. If the patient will not or cannot eat, however, nutritional intervention may be indicated. Examples of patients who will not eat include those with anorexia due to tumor or chemotherapy, and those with anorexia nervosa. Such patients generally have a normal or near-normal nonobstructed bowel, and can be fed enterally. Patients who cannot eat because of severe gastrointestinal illness include those with bowel obstruction or ileus. If nutritional intervention is required in these patients, parenteral (intravenous) nutrition will be necessary. These tubes can be placed through the pylorus to feed into the jejunum with only local anesthetic and mild sedation. Despite convincing evidence of efficacy of post-pyloric placement of tubes in reducing pulmonary aspiration, the tube is usually placed in the jejunum if aspiration is a concern. The formulas have been traditionally divided into polymeric, oligomeric, monomeric, modular and disease-specific formulas. Polymeric formulas (also called defined formula diets) provide nitrogen as whole protein, often casein, egg white solids or soy protein. Carbohydrate is often provided as corn syrup, maltodextrins or glucose oligosaccharides, with sucrose added for sweetness in oral formulas. Fat is usually provided as soy oil, although corn oil and safflower oil may be used. Protein may be provided as milk (usually dry or skim), with lactose as a major carbohydrate. Specialized polymeric formulas are available for a variety of disease states, including kidney and lung disease as well as diabetes. Some contain fiber and others are prepared for oral consumption (generally sweeter with a higher osmolality than those meant primarily for tube feeding). Oligomeric formulas (also called semi-elemental diets) provide nitrogen as peptides from partially hydrolyzed whole protein. Monomeric formulas (also called elemental diets) provide nitrogen as crystalline amino acids. Fat is usually present in small quantities, enough to meet the requirement for linoleic acid (an essential fatty acid), which is about 24% of total calories. The oligomeric and monomeric diets were formulated to require minimal digestion by the gastrointestinal tract, with little necessity for bile and pancreatic secretions, and minimal work by the enterocyte in terms of brush-border enzyme activity or re-esterification. Hence, these diets have been commercially promoted as ideal for patients with decreased bile output (cholestasis), pancreatic insufficiency and short bowel. However, there is little evidence First Principles of Gastroenterology and Hepatology A. Finally, the high cost of these diets (often five to 10 times that of polymeric diets) rarely justifies their use. For liver disease, these solutions are composed mostly or exclusively of branched-chain amino acids, whereas for renal disease the solutions are predominantly essential amino acids. There has been considerable interest in immunonutrition which refers to formulas which have been enriched with nutrients purported to alter immunity. Such nutrients include amino acids such as arginine and glutamine, fish oil (omega-3 fatty acids), antioxidants and nucleotides. Systematic reviews of immunonutrition have been reported in intensive care and surgical patients but the role of these specialized products remains controversial. In general, enteral feeding is well tolerated, and provided the complications are known, preventive and/or corrective measures may be undertaken to minimize patient risk. Aspiration of the infused formula, with development of pneumonia, is a potentially lethal complication of tube feeding. Risk factors for aspiration include patients on a ventilator and those with gastroesophageal reflux, poor or absent gag reflex, and impaired mentation. To minimize aspiration, it is suggested that patients, when possible, be fed with the head of the bed elevated 2030. Gastric contents should initially be checked by aspirating the tube every four to six hours and if the residual volume is > 150 mL, the infusion should be temporarily stopped. Unfortunately, the small nasoenteric tubes in current use often collapse when aspirated, so small returns do not guarantee that the stomach is not becoming distended with fluid. Hence, examination for epigastric distention and succussion splash should be done. If there is any concern, an upright (if possible) plain film to assess gastric size may be useful. It has also been suggested that the feeding tube be placed into the small bowel well beyond the pylorus to minimize aspiration in those at risk, though studies have failed to confirm this. The following mechanical problems in patients with nasoenteric tubes include problems in the upper respiratory tract and esophagitis with development of esophageal ulceration, stenosis and even tracheoesophageal fistula. Upper respiratory problems include pharyngeal irritation, nasal erosions and necrosis, sinusitis and otitis media. These mechanical problems can be largely avoided by the use of soft, small-bore nasoenteric tubes. Gastrointestinal problems related to nasoenteric feeding are common, occurring in 2030% of patients. The most frequent complaints are nausea, vomiting, abdominal distention and altered bowel habit. Symptoms may be minimized by feeding at a slow rate with dilute solutions, but these symptoms may be just as common as with full-rate, full-strength solutions. If a lactose-containing solution is being used (generally First Principles of Gastroenterology and Hepatology A. Shaffer 665 not recommended for tube feeding), changing to a lactose-free solution is indicated. For constipation, fiber-containing solutions may be tried, although they are often unhelpful.

Problemswithsexualfunctioninpeopleattendinggeneral of the role of testosterone in erectile function: from pathophysiology to treatment buy cipro 750mg online. Angiography and endovascular revascularization of pudendal review and meta-analysis purchase cipro 500 mg online. Erectile dysfunction (impotence) is the inability to get or keep an erection sufficient for sexual intercourse proven cipro 250 mg. One in ten men (10%) suffer from impotence and it is seen in almost one third (30%) of diabetic men. However, many men suffer erectile dysfunction in silence, without seeking help or advice. During arousal, nerve impulses travel from the brain to the penis and trigger smooth muscle relaxation in the penis. During enlargement, the veins in the penis become compressed, blocking the flow of blood out of the penis so that erection occurs. If the blood supply is poor, your penis may not fill with blood, the veins will not be compressed and what blood there is will leak out of the penis. In men with diabetes, the commonest causes of erectile dysfunction are disease of the blood vessels and nerve damage (often in combination). It is very common to see a combination of psychological and physical causes, but pure psychological causes are seen in less than 1 in 10 (10%) of all affected patients. When a man has difficulty getting an erection, whatever the cause, he will often experience pressure to perform. This can lead to a feeling of inadequacy and a sense of loss of manhood (called performance anxiety). Blood tests should be carried out first thing in the morning, preferably around 09. We will, of course, give you guidance on what we feel is most appropriate for you. Originally, the Department of Health guidance stated that prescribing for those with erectile dysfunction causing severe distress should only be done by specialist services. In summary, the basic treatment options are: Psychosexual counselling Some men need counselling and will be referred to a specialist in this area. Vacuum erection assistance devices Vacuum erection assistance devices are a non-invasive method of obtaining and sustaining an erection in men with impotence (erectile dysfunction). You get an erection by creating a negative pressure inside the cylinder, using a hand-operated or battery- powered pump. Tablet treatment First-line treatment for most patients is now tablet treatment using sildenafil (generic or Viagra), tadalafil (Cialis), vardenafil (Levitra) or avanafil (Spedra). Hormone treatment This is only offered to patients who are deficient in male hormones. Hormone treatment will not improve erections in men who do not have hormone deficiency (and may even be harmful in this situation). Self-injection therapy This treatment involves injecting a drug into the side of your penis each time you want an erection. The injection causes the muscles in your penis to relax which encourages blood to flow into your penis. Injection therapy is very effective but some men find the idea difficult to accept. Injections can be used up to twice a week but you should never inject yourself more than once in any 24-hour period. For example, your erection may not go down and you then need to come to hospital to have it reversed. Intra-urethral pellets or cream This involves insertion of a pellet of prostaglandin into the urethra (waterpipe). Penile implants This is an invasive surgical procedure which involves putting prostheses (implants) into your penis to allow you to achieve erections for sexual intercourse. Penile implants are reserved for patients who have tried and failed other medical treatments such as tablets, injections, vacuum devices or pellets. It may also be used in patients with other conditions in which erections have been affected, such as following priapism (prolonged painful erections) or in men with Peyronies disease. Your treatment will be planned with the doctors responsible for your care, considering not only which drugs are, or are not, available at your local hospital but also what is necessary to give you the best quality of care. Disclaimer We have made every effort to give accurate information in this leaflet, but there may still be errors or omissions. Erectile dysfunction (also known as impotence) is the inability to get and keep an erection firm enough for sex. But if erectile dysfunction is an ongoing problem, it may cause stress, cause relationship problems or affect your self-confidence. Even though it may seem awkward to talk with your doctor about erectile dysfunction, go in for an evaluation. Problems getting or keeping an erection can be a sign of a health condition that needs treatment, such as heart disease or poorly controlled diabetes. Treating an underlying problem may be enough to reverse your erectile dysfunction. Likewise, stress and mental health problems can cause or worsen erectile dysfunction. Sometimes a combination of physical and psychological issues causes erectile dysfunction. For instance, a minor physical problem that slows your sexual response may cause anxiety about maintaining an erection. The brain plays a key role in triggering the series of physical events that cause an erection, starting with feelings of sexual excitement. A number of things can interfere with sexual feelings and cause or worsen erectile dysfunction. These include: Depression, anxiety or other mental health conditions Stress Fatigue Relationship problems due to stress, poor communication or other concerns What are the risk factors for Erectile Dysfunction? Over time tobacco use can cause chronic health problems that lead to erectile dysfunction. If your doctor suspects that underlying problems may be involved, or you have chronic health problems, you may need further tests or you may need to see a specialist. This may include careful examination of your penis and testicles and checking your nerves for feeling. A sample of your blood may be sent to a lab to check for signs of heart disease, diabetes, low testosterone levels and other health problems. Like blood tests, urine tests are used to look for signs of diabetes and other underlying health conditions. It involves using a wand-like device (transducer) held over the blood vessels that supply the penis. This test is sometimes done in combination with an injection of medications into the penis to determine if blood flow increases normally. This simple test involves wrapping special tape around your penis before you go to bed. If the tape is separated in the morning, your penis was erect at some time during the night. This indicates the cause is of your erectile dysfunction is most likely psychological and not physical. These drugs enhance the effects of nitric oxide, a natural chemical your body produces that relaxes muscles in the penis. This increases blood flow and allows you to get an erection in response to sexual stimulation. Your doctor will take into account your particular situation to determine which medication may work best. You may need to work with your doctor to find the right medication and dose for you. Although these medications can help many people, not all men should take them to treat erectile dysfunction.
By definition buy cheap cipro 750mg online, however cheap cipro 500 mg otc, clinical and histological improvement results from a strict gluten-free diet buy 750 mg cipro with visa, and relapse occurs with re-introduction of dietary gluten discount 750 mg cipro amex. Learn to suspect and test for it in persons with typical gastrointestinal symptoms, as well as knowing when to screen for celiac disease in persons with associated disorders, such as autoimmune conditions. Although early autopsy descriptions for celiac disease are available, an evolution in technology for procurement of small intestinal biopsies led to earlier clinical diagnosis, and an explosion of information on many disorders of the small intestine, besides celiac disease. In recent years, the extended recognition of clinical features and protean presentations of celiac disease has resulted in markedly improved awareness. Finally, development of improved screening methods in the laboratory has resulted in appreciation that celiac disease is common, particularly in Europe and North America, with rates of about 1 in every 100 persons. Definition of celiac disease in adults depends on two sequential criteria: first, demonstration of the typical biopsy changes of untreated celiac disease; and second, improvement with absolute dietary gluten restriction. Most often, resolution of diarrhea and evidence of weight gain is sufficient to establish improvement. In others, especially in children, a second set of intestinal biopsies after a prolonged period of dietary gluten restriction may be needed to document this improvement. High Risk Populations The true prevalence of celiac disease has not been defined, in part, because many are now recognized for the first time with atypical, few or no symptoms. Some have suggested that screening measures have especially increased recognition of celiac disease, at least in comparison to those known to have already established disease. In North Americans, the reported general population prevalence is approximately 1:100 (1%) with a range of 1:80 to 1:140 (1. A study in Swedish youth (<20 years old) diagnosed with Type 1Diabetes confirmed the low prevalence (0. High-risk groups that exceed this general population prevalence are listed in Table 1. However, for unknown reasons this female sex preponderance disappears with increased aging. These may include perinatal infections, or viral infections such as Adenovirus 12 and Hepatitis C virus (Plot and Amital, 2009). The timing was possibly owing to the time of introduction of cereal grains into their diet. Now, however, it is appreciated that most clinically evident celiac disease is usually first detected between ages 25 and 40 years, not during childhood. Furthermore, in recent years the initial definition of celiac disease in the elderly has become increasingly appreciated, with some studies recording that about 20% of celiacs are older than age 60 years. Clinical Gem While the peak age of diagnosis of persons with celiac disease is 25-40 years of age, initial diagnosis of celiac disease may be established at any age, including the elderly. The highest reported prevalence of celiac disease is from western European countries, North America, particularly Canada and the United States, and Australia. Celiac disease also occurs in the Indian subcontinent, particularly in the Punjab region of northwest India as well as in Indian emigrants to the United Kingdom and Canada. Celiac disease has also been described in First Nations persons living on the west coast of Canada; these persons sometimes also have other concomitant immune-mediated disorders. Pathogenesis Celiac disease results from the interaction between dietary gluten and specific immune, genetic and environmental factors. The current pathogenesis can be summarized as follows: in genetically-primed individuals, an inappropriate T-cell mediated immune response occurs against ingested dietary gluten, the major storage protein of wheat and related grains. This response leads to inflammation mostly in the proximal small intestine, loss or shortening of intestinal villi, and both intestinal as well as extra-intestinal symptoms. When gluten is withdrawn from the diet, these abnormalities improve, or disappear. Immune Factors Gluten generally refers to the entire protein content of wheat, rich in glutamine and proline. Most proteins or peptides that arrive in the proximal small intestine can be digested by luminal and brush border hydrolytic enzymes into amino acids and peptides. Gluten and other proline-rich proteins are poorly digested in the normal human small intestine, because of an apparent deficiency of prolyl-endopeptidases. A number of gluten peptides that may be up to 50 amino acids long can result from this hydrolytic process. For example, undigested gliadin (the alcohol-soluble fraction of gluten) molecules include the 33-mer (composed of 33 amino acids) and 19-mer (composed of 19 amino acids) alpha-gliadin fractions. This is resistant to enzyme digestion, and most of this gliadin remains in the intestinal lumen after gluten is ingested. Gliadin (high in glutamine) entering the lamina propria may also be deamidated by the enzyme, tissue transglutaminase. This causes conversion of glutamine in these peptides to negatively-charged glutamic acid residues. As a result, villous atrophy and crypt hyperplasia develop along with activation and expansion of B-cells which produce antibodies. A humoral or B-cell immune response also appears to be directed towards the First Principles of Gastroenterology and Hepatology A. Shaffer 234 exogenous antigen, gluten (19-mer alpha gliadin fraction), and the autoantigen, tissue transglutaminase. The toxic peptides, such as the 19-mer, trigger an innate immune response (Maiuri et al. There are large variations in the amount of deamidation between different peptides, and between individual glutamine residues within each peptide (Drum et al. The elevated urine levels of indoxyl sulfate, meta- [hydroxyphenyl]proprionic acid and phenyl acetylglycine suggest that there are alterations in the gut microbiotica. Since these abnormalities returned to normal in 95% of the persons when treated with a gluten-free diet for a year, these alterations were likely the result of the gluten- First Principles of Gastroenterology and Hepatology A. Genetic Factors Celiac disease occurs in about 10 to 20% of first-degree relatives of the index patient. This indicates that these genes are necessary but not sufficient alone to cause the disease. Environmental Factors A number of environmental factors may play a role in pathogenesis of celiac disease. Breast feeding may be protective and introduction of dietary gluten prior to 3 months of age may increase the risk of disease development. Some viral infections (adenovirus, rotavirus) have also been implicated in earlier studies. Identifying these environmental triggers will be important to explain why some genetically at-work persons who have consumed gluten for many years may first develop symptoms at an older age. Most clinicians assume that childhood celiac disease and adult celiac disease are similar, but differences, particularly in their pathogenesis and clinical features, do occur. Indeed, some, but not all physicians believe that disease first detected in adults reflects long-standing sub-clinical disease in children that only becomes clinically evident as adults. Others believe that the disease may be much more heterogeneous, and may become initially activated in a genetically-predisposed person much later in life. Childhood Celiac Disease Most children with celiac disease become clinically apparent after age 4 months, but often before 2 years. Historically, this was believed to be related to the introduction of dietary cereal grains as well as weaning from breast feeding. Most often, in childhood, the disease is insidious with slowing of growth prior to the onset of weight loss. With clinically-evident disease, short stature, delay of puberty, pallor and anemia associated with iron and/or folic acid deficiency may develop. Irritability and behavioral disorders, including depression and poor school performance may occur. Rickets was reported in earlier historical experiences, but is not so evident now. The initial detection of celiac disease in older children and adolescents is less common. However, in children on a gluten free diet for previously diagnosed celiac disease, symptoms First Principles of Gastroenterology and Hepatology A.

The sooner you see a doctor, the sooner you can receive treatment for any other serious medical problems you may have. By getting a diagnosis and controlling the erectile problems early, the damage done to the tissues of your body (including the penis) may be reduced. The local doctor is the best frst point of contact if he should have you have erectile problems. Often the local doctor At frst, the doctor will need to talk to you to fnd a face to face can treat erectile problems without the need to refer out more about the problem.

More clarity was needed around the advantages of for-profit companies collaborating with a non-profit antibiotic developer and the financing model cheap cipro 1000 mg with visa. Market entry reward A market entry reward is a series of substantial generic cipro 750mg online, annual payments made to an innovator who achieves regulatory approval for a new antibiotic meeting specified requirements buy cipro 500mg otc, including target pathogens discount cipro 1000 mg with mastercard. By accepting the payment, the developer contractually agrees to a set of stipulations regarding global availability, regulatory maintenance and sustainable use provisions. In a fully delinked model, all developer revenues come from the reward payment(s) whereas in a partially delinked model, revenues are achieved both from the reward payment(s) and unit sales. However, in a fully delinked model the healthcare providers will need to pay a higher unit price to avoid the economic incentive to overuse the antibiotic. Market entry rewards were judged to strongly stimulate innovation, with the partially delinked version receiving slightly higher support. There were concerns about the financial feasibility of the fully delinked model and thus sustainability and implementation. Stakeholders were sceptical of one global implementation of either model, highlighting the complexity, amount of financing, and level of consensus required. Participants mentioned that it would be difficult to safeguard such a large pot of money from other political agendas. The fully delinked model was judged to strongly support sustainable use and equitable availability, but there were concerns that the partially delinked model would be less effective in these areas. There were also concerns about the national complexity of the implementation of a fully delinked model, especially the ability of governments to set unit prices of novel antibiotics for their healthcare providers. If the threshold volume limit (sometimes called the collar) is exceeded, then the payer would provide an additional amount (either per treatment or a fixed amount to a higher threshold). In a variation of this model (the cap and collar model), there is an additional threshold (the cap) where there is revenue-sharing between the manufacturer and the payer. It was acknowledged that this could be a strong model to ensure national access to critical antibiotic therapies, such as colistin. There was uncertainty about the models ability to promote global access to antibiotics, and about whether the model could be implemented in low- and middle-income countries. Diagnosis confirmation model The diagnosis confirmation model is a diagnosis-driven, dual-pricing model where a premium price is charged if the antibiotic is used for the entire course (based on a confirmed diagnosis or clinical decision) or a lesser price if the antibiotic is used first empirically and then promptly de-escalated after the receipt of the diagnostic/laboratory results. Some commented that since this model could be implemented today, it was unclear how this would improve antibacterial R&D incentives. The model was judged as financially feasible, implementable nationally, and compatible with national regulatory and reimbursement systems. In the discussion, stakeholders questioned if dual pricing was actually necessary. Some commented that hospitals must implement strict controls for budgetary reasons when using any extremely highly-priced products. These controls may be as effective for sustainable use as the dual-pricing mechanism. Some participants stated that diagnostic results were not always clear and that physicians might continue to administer the antibacterial therapy as long as the patient was improving. There was a general concern that the model promoted empiric use of a novel antibiotic. Discussion Throughout our assessments we have been clear that there is a need for different incentive models depending on the type of infection and patient population. The models need to ensure that risk and royalties are shared between stakeholders. Grants and market entry rewards (both partially and fully delinked models) received strong support and clearly needed further development and assessment. The non-profit antibiotic developer was transformed, based upon the feedback, into the pipeline coordinator, with more emphasis on collaboration with the private sector. The insurance licence model was shifted from an innovation to an access incentive, entitled the long-term supply continuity model, to be used to maintain reliable access to important but rarely used generic antibiotics. The diagnosis confirmation model was excluded because of its inability to be paired with any equitable availability models and because market entry rewards were deemed a stronger incentive. There is no one size fits all solution to incentivizing antibiotic innovation in a global market with a huge variety of unmet needs, healthcare systems and access requirements. A menu of incentives is required that can be adapted to the local context and yet still achieve the same goal of stimulating antibacterial innovation. The fund governments would be willing to do so on a runs parallel to the long-term basis, not only because of the traditional large sums involved but also given that the reimbursement system. If payout is based upon a ranking of global a company voluntarily health impact and theoretically could result opts into payments from in large payments to patented antibiotics the fund, it agrees to sell that offer little public health benefit. It then receives would be likely to deter private-sector an annual payment based investment. This mechanism is also upon the amount of complicated, requiring significant funds to financing in the fund, administer.

It also prevents sudden dilatation of the cardiac chambers during exercise and hypervolumia proven 750 mg cipro. It restricts the anatomic position of the heart and minimizes friction with the surrounding structures discount 750 mg cipro visa. Approximately 120 cc of additional fluid can accumulate in the pericardium without an increase in pressure purchase 1000mg cipro. Further fluid accumulation can result in marked increases in pericardial pressure effective cipro 1000 mg, eliciting decreased cardiac output and hypotension (cardiac tamponade). Classification of Pericarditis Clinical classification Etiologic Classification I. Clinical features Pericarditis The most common symptom of acute pericarditis is precordial or retrosternal chest pain, usually described as sharp or stabbing. Physical findings: Pericarditis The classic sign of acute pericarditis is pericardial friction rub, which is scratchy, leathery sound heard during both systole and diastole. It is best, heard at the lower left sternal border or apex when the patient is positioned sitting forward. Friction rub may be transient from one hour to the next and is present in approximately 50% of cases. A friction rub may be distinguished from a cardiac murmur by its changing character from heartbeat to heartbeat and patient position changes. Cardiac tamponade As the volume of pericardial fluid increases, the capacity of the atria and ventricles to fill is mechanically compromised, leading to reduced stroke volume and tamponade. In cardiac tamponade (or large effusions), the chest x-ray may demonstrate an enlarged cardiac silhouette after 200-250 ml of fluid accumulation. This occurs in patients with slow fluid accumulation, compared to a normal cardiac silhouette seen in patients with rapid accumulation and tamponade. Thus, the chronicity of the effusion may be suggested by the presence of a huge cardiac silhouette. Cardiac tamponade Patients with evidence of cardiac tamponade need emergency pericadiocentesis i. Prognosis: The prognosis of pericarditis depends upon the etiology of the pericardial infection or inflammation as well as the presence of a pericardial effusion and/or tamponade. Ischemic Heart Diseases Learning objectives: at the end of this lesson the student will be able to: 1. Background Ischemic Heart Diseases manifests due to an imbalance in myocardial oxygen supply and demand, that results in myocardial hypoxemia. The most common cause of myocardischemia is atherosclerotic disease of the coronary arteries. Myocardial oxygen demand is mainly determined by heart rate, the force of ventricular contraction, and ventricular wall tension, which is proportional to the ventricular 271 Internal Medicine volume and pressure. Atherosclerosis is focal narrowing of arteries which results from a plaque formation. Plaques are formed as a result of Intimal smooth muscle proliferation probably as a result of endothelial damage Lipids ( Cholesterol esters ) are deposited at the center of plaques and also with in smooth muscle cells A fibrous cup made of connective tissue covers the plaque As the stenotic lesions grow, perfusion pressure distal to the lesions decreases; in response, coronary arterioles dilate to maintain adequate blood flow preventing ischemic symptoms at rest. During exertion the myocardial oxygen demand increases which couldnt be matched by 272 Internal Medicine the perfusion via the narrowed coronary artery. The resulting myocardial ischemia results in chest pain, called angina pectoris, which is relived by taking rest. Sometimes atherosclerotic plaques may rapture and a fibrin thrombus is formed overe the plaque which completely blocks the narrowed coronary artery and result in myocardial infarction. The symptom usually begins with low intensity, increase over 2-3 minutes and often lasts less than 15 minutes. Episodes lasting morethan30 minutes suggest myocardial infarction may have occurred Types of Angina A. Chromic stable angina: angina which recurs under similar circumstances and with similar frequency over time. Silent ischemia: for every episode of symptomatic ischemia that the patient suffers, there are usually four to five episodes of silent (asymptomatic) ischemia. Unstable angina is progressive and it may be ominous feature of imminent myocardial infarction. So physicians and patients should be aware that close observation and intensive therapy are required. New onset angina is an angina that progresses in severity, duration or frequency over 1-or 2 months 273 Internal Medicine ii. Resting angina: is particularly worrisome because it implies decreased supply, rather that increased demand, is causing angina. Varian ( Prinzmetals ) angina : This is a type of angina resulting from transient coronary spasm, which usually but not always associated with fixed atherosclerotic lesion. These drugs are especially effective in preventing coronary spasm that cause variant angina. B Acute Care/Hospitalization: Always refer patients presenting with new-onset, rest, or increasing angina to an emergency department, and hospitalize a patient with clinical evidence of unstable angina or myocardial infarction. Surgical interventions: Percutanous transluminal coronary angioplasty Artherectomey Coronary artery bypass surgery Complications In patients with chronic stable angina, be sensitive particularly to accelerating symptoms, indicating development of unstable angina. The pain usually occurs when the patient is a rest or involved in minimal activity. This may include ventricular tachycardias and ventricular fibrillation Atrial arrhythmias; atrial fibrillation and atrial flutter Acute conduction system abnormality The conduction system may be part of the myocardium affected during infarction. Mitral regurgitation: may occur if the papillary muscles are affected by infarction. Cardiac rapture: Myocardial infarction of the free wall may lead to eventual perforation of the heart. This complication, which results overwhelmingly cardiac tamponade, is nearly always fatal. Left ventricular aneurysm: The infracted myocardium may evaginate and heal with fibrous connective tissue. Emergency management :Management of patients should start before they reach the hospital emergency room 1. Contraindication: History of Cerebrovascular hemorrhage, marked hypertension, bleeding disorder. When performed by experienced physicians the short and long term outcomes are much better than what can be archived through thrombolysis or fibrinolysis. Fibrous diet and Stool softeners like bisacodyl or Dioctyl sodium sulfosuccinate 200 mg /day are recommended. The extent of ventricular damage: left ventricular ejection fraction An ejection fraction of <40 % doubles the yearly mortality rate at each level of extent of coronary disease. Revascularization: significantly improves the short term and long term morbidity and, mortality when it is done at the right time by an expert hand. Cardiac Arrhythmias Learning objectives: at the end of this lesson the student will be able to: 1. Refer patients with arrhythmias to appropriate centers Definition: Cardiac arrhythmias are changes in the regular beating of the heart. The heart may seem to skip a beat or beat irregularly or beat very fast or very slow. In these cases, heart disease, not the arrhythmia, poses the greatest risk to the patient. Almost everyone has also felt dizzy, faint, or out of breathe or had chest pains at one time or another. They result from inadequate sinus impulse production or from blocked impulse propagation. They are not usually cause of concern unless the patient develops syncope or presyncope. Sick sinus syndrome: The sinus node does not fire its signals properly, so that the heart rate slows down. Sometimes the rate changes back and forth between a slow (bradycardia) and fast (tachycardia) rate 3. Often conduction is in a ration of 2: 1and it is prolonged enough to cause symptomatic bradycardia. The heart rate drops significantly to a range of 20- 40 beats/min and patients become symptomatic.
