What is Angina? what is the remedy? ================================RESPONSE: Angina refers to the hurting originating from deficiency of equal blood supply to theheart musculus. Typically, it is a suppression hurting behind the sternum in thecenter of the thorax, brought on by effort and relieved by remainder. It may attimes radiate to or originate in the left arm, cervix, jaw, left chest, orback. It is often accompanied by sudating, palpitations of theheart, and by and large lasts a affair of proceedingss. Similar hurting syndromesmay be caused by other diseases, including esophagitis, gall bladderdisease, ulcers, and others. Diagnosis of angina Begins with the acknowledgment of the consistentsymptoms. Often an exercising trial with radioactive Tl is performedif the diagnosing is in inquiry, and sometimes even a cardiaccatheterization is done if the result is felt necessary to makemanagement determinations. This is a complex country which requires carefuljudgment by physician and patient. Angina is a manifestation of coronary arteria disease, the samedisease taking to bosom onslaughts. Coronary arteria diseas refers tothose syndromes caused by obstruction to the flow of blood in thosearteries providing the bosom musculus itself, i.e. , the coronary arterias. Like any other organ, the bosom requires a steady flow of O andnutrients to supply energy for rmovement, and to keep the delicatebalance of chemicals which allow for the careful electrical rhythmcontrol of the bosom round. Unlike some other variety meats, the bosom cansurvive merely a affair of proceedingss without these foods, and the restof the organic structure can last merely proceedingss without the bosom & # 8211 ; therefore thecritical nature of these syndromes. Causes of obstruction scope from inborn tissue strands within orover the arterias to cramps of the muscular coat of the arteriesthemselves. By far the most common cause, nevertheless, is the deposition ofplaques of cholesterin, thrombocytes and other substances within thearterial walls. Sometimes the buildup is really gradual, but in othercases the buildup is all of a sudden increased as a ball of affair interruptions offand all of a sudden blocks the already narrowed gap. Certain factors seem to prefer the buildup of these plaques. A strongfamily history of bosom onslaughts is a definite hazard factor, reflectingsome metabolic mental unsoundness in either cholesterin handling or some otherfactor. Bing male, for grounds likely related to the protectiveeffects of some female endocrines, is besides a comparative hazard. Cigarettesmoking and high blood force per unit area are definite hazards, both reversible in
& lt ;most cases. Risk also increases with age. Elevated blood cholesterollevels (both total and low density types) are risks, whereas the highdensity cholesterol level is a risk only if it is reduced. Possible,but less well-defined factors include certain intense and hostile ortime-pressured personality types (so-called type A), inactive lifestyle,and high cholesterol diets. Medications are increasingly effective for symptom control, as wellas prevention of complications. The oldest and most common agents arethe nitrates, derivatives of nitroglycerine. They includenitroglycerine, isosorbide, and similar agents. Newer forms includelong acting oral agents, plus skin patches which release a small amountthrough the skin into the bloodstream over a full day. They act byreducing the burden of blood returning to the heart from the veins andalso by dilating the coronary arteries themselves. Nitrates are highlyeffective for relief and prevention of angina, and sometimes forlimiting the size of a heart attack. Used both for treatment ofsymptoms as well as prevention of anticipated symptoms, nitrates areconsidered by many to be the mainstay of medical therapy for angina. The second group of drugs are called “beta blockers” for theirability to block the activity of the beta receptors of the nervoussystem. These receptors cause actions such as blood pressure elevation,rapid heart rate, and forceful heart contractions. When these actionsare reduced, the heart needs less blood, and thus angina may be reduced. The newest group of drugs for angina is called the calcium channelblockers. Calcium channels refer to the areas of the membranes of heartand other cells where calcium flows in and out, reacting with otherchemicals to modulate the force and rate of contractions. In the heart,they can reduce the force and rate of contractions and electricalexcitability, thereby having a calming effect on the heart. Althoughtheir final place in heart disease remains to be seen, they promise toplay an increasingly important role. When medications are unsuccessful, or if there is concern about animpending or potential heart attack, coronary bypass surgery is highlysuccessful in reducing symptoms. Whether or not it prolongs survival isquestionable for most patients. Angina which is new or somehow different from previous episodes inany way is termed unstable angina, is a medical emergency, andrequires urgent attention. Research is active, and careful medicalfollow-up is important.mergency, andrequires urgent attention. Research is active, and careful medicalfollow-up is important.
