what are a normal causes for a heart attack?

Answer 1

Acute myocardial infarction (AMI or MI), commonly known as a heart attack, is a disease that occurs when the blood supply to a part of the heart is interrupted, causing death of heart tissue. It is the leading cause of death for both men and women all over the world.[1]

The term myocardial infarction is derived from myocardium (the heart muscle) and infarction (tissue death due to oxygen starvation or ischemia). The phrase "heart attack" sometimes refers to heart problems other than MI, such as unstable angina pectoris and sudden cardiac death.


Symptoms
Acute myocardial infarction is usually characterized by varying degrees of chest pain, discomfort, sweating, weakness, nausea, vomiting, and arrhythmia, sometimes causing loss of consciousness and even sudden death. Chest pain is the most common symptom of acute myocardial infarction and is often described as a sensation of tightness, pressure, or squeezing. Pain radiates most often to the left arm, but may also radiate to the jaw, neck, right arm, back, and epigastrium. The patient may complain of shortness of breath (dyspnea) especially if the decrease in myocardial contractility due to the infarct is sufficient to cause left ventricular failure with pulmonary congestion or even pulmonary edema. Approximately half of all MI patients have experienced warning symptoms like angina pectoris prior to the infarction.

Women often experience different symptoms than men. The most common symptoms of MI in women include dyspnea, weakness, and fatigue. Fatigue, sleep disturbances, and dyspnea have been reported as frequently occurring prodromal symptoms which may manifest as long as one month before the actual clinically manifested ischemic event. In women, chest pain may be less predictive of coronary ischemia than in men[2]

Approximately one third of all myocardial infarctions are silent, without chest pain or other symptoms.[3] This happens more often in elderly patients and patients with diabetes mellitus.[4]
