Question: 1 / 400

True or false: Angina pectoris is another name for myocardial infarction.

True

False

Angina pectoris refers to chest pain or discomfort caused by reduced blood flow to the heart muscle, usually due to coronary artery disease. It is a symptom of an underlying condition rather than a diagnosis in itself. This pain often occurs during exertion or stress and is usually relieved by rest or medication, such as nitrates.

On the other hand, myocardial infarction, commonly known as a heart attack, occurs when blood flow to a part of the heart is blocked for a prolonged period, leading to damage or death of the heart muscle tissue. This condition is often a result of a complete blockage in a coronary artery and is a medical emergency.

The distinction lies in the fact that angina pectoris is a signal of impending heart issues, while a myocardial infarction is a significant event that requires immediate medical intervention. Therefore, the statement equating the two is false.
