What is Angina? And what is the cure?

Extracts from this document...


What is Angina? And what is the cure? Angina refers to the pain arising from lack of adequate blood supply to the heart muscle. Typically, it is a crushing pain behind the breastbone in the centre of the chest, brought on by exertion and relieved by rest. It may at times radiate to or arise in the left arm, neck, jaw, left chest, or back. It is frequently accompanied by sweating, palpitations of the heart, and generally lasts a matter of minutes. Other diseases, including esophagitis, gall bladder disease, ulcers, and others may cause similar pain syndromes. Diagnosis of angina begins with the recognition of the consistent symptoms. Often an exercise test with radioactive thallium is performed if the diagnosis is in question, and sometimes even a cardiac catheterization is done if the outcome is felt necessary to make management decisions. This is a complex area which requires careful judgment by physician and patient. ...read more.


Sometimes the buildup is very gradual, but in other cases the buildup is suddenly increased as a chunk of matter breaks off and suddenly blocks the already narrowed opening. Certain factors seem to favour the build up of these plaques. A strong family history of heart attacks is a definite risk factor, reflecting some metabolic derangement in either cholesterol handling or some other factor. Being male, for reasons probably related to the protective effects of some female hormones, is also a relative risk. Cigarette smoking and high blood pressure is definite risks, both reversible in most cases. Risk also increases with age. Elevated blood cholesterol levels (both total and low density types) are risks, whereas the high-density cholesterol level is a risk only if it is reduced. Possible, but less well-defined factors include certain intense and hostile or time-pressured personality types (so-called type A), inactive lifestyle, and high cholesterol diets. ...read more.


The newest group of drugs for angina is called the calcium channel blockers. Calcium channels refer to the areas of the membranes of heart and other cells where calcium flows in and out, reacting with other chemicals to modulate the force and rate of contractions. In the heart, they can reduce the force and rate of contractions and electrical excitability, thereby having a calming effect on the heart. Although their final place in heart disease remains to be seen, they promise to play an increasingly important role. When medications are unsuccessful, or if there is concern about an impending or potential heart attack, coronary bypass surgery is highly successful in reducing symptoms. Whether or not it prolongs survival is questionable for most patients. Angina that is new or somehow different from previous episodes in any way is termed unstable angina, is a medical emergency, and requires urgent attention. Research is active, and careful medical follow-up is important mergence, and requires urgent attention. Research is active, and careful medical follow-up is important. ...read more.
