Myocardial infarction

Sometimes called a "coronary" or a "heart attack", myocardial infarction is a condition caused by occlusion of one or more of the coronary arteries. The symptoms include prolonged heavy pressure or squeezing pain in the center of the chest behind the sternum (breast bone). Typically, the patient will describe this by clenching a fist and holding it over the heart to demonstrate the character of the pain. The pain may spread to the shoulder, neck, arm, and fourth and fifth fingers of the left hand, to the back, to the teeth, or to the jaw. These symptoms may be accompanied by nausea and vomiting, sweating, and shortness of breath. The may come and go. It is important that medical care be obtained without delay. About half of myocardial infarction patients die prior to reaching the hospital. Delaying specific therapy may cause loss of life. When the coronary arteries that supply the heart with oxygen thicken, harden, and narrow, the heart is deprived of needed oxygen. This deprivation often results in chest pain, called angina pectoris. When damage to the heart muscle is incurred, the individual suffers a heart attack or myocardial infarction. In addition to insufficient blood flow to the heart can cause abnormal heartbeat rhythms called arrhythmias. A coronary may be triggered by a partial or complete blockage of the coronary arteries, an emotional crisis, a heavy meal, or overexertion from exercise or heavy lifting. Cardiac failure is a condition resulting fro inability of the heart to pump sufficient blood to meet the needs of the body. Following a coronary, the heart muscles may be damaged or scarred, resulting in the inability of the heart to perform normally. Cardiac insufficiency is the inadequate cardiac output due to failure of the heart to function properly, as in valvular deficiency.

Heart Attack

A heart attack, clinically known as a myocardial infarction, occurs when an artery supplying the heart with blood carrying oxygen and nutrients suddenly becomes blocked, causing part of the heart muscle to die. Because your heart is a muscle, it needs oxygen to function, just like any other tissue. The special blood vessels that feed the heart are called coronary arteries. Coronary artery disease is a process of narrowing that occurs over time in these important vessels and can lead to a heart attack. The narrowing is caused by the build-up of fats and plaques in arteries, and can exist and grow without any symptoms.
