Question

What acute disorder of the cardiovascular system is caused by a sudden blockage of the coronary arteries?

a) Angina pectoris
b) Myocardial infarction
c) Chronic heart failure
d) Stroke

Answer 1

Myocardial infarction, also known as a heart attack, occurs when there is a sudden blockage of the coronary arteries, restricting blood flow and oxygen to the heart muscle.

Step-by-step explanation:

Myocardial infarction, also known as a heart attack, occurs when there is a sudden blockage of the coronary arteries, restricting blood flow and oxygen to the heart muscle. This results in the death of cardiac muscle cells. A heart attack can cause symptoms such as chest pain, and if left untreated, it can lead to heart arrhythmias, heart failure, or cardiac arrest.
