What condition can result from a blockage of a coronary artery?

A blockage of a coronary artery can lead to a heart attack, also known as a myocardial infarction. This occurs because the coronary arteries supply blood to the heart muscle, and if they become blocked, the flow of oxygen-rich blood is restricted or cut off. When the heart muscle does not receive enough oxygen, it can begin to die, leading to chest pain, discomfort, or other serious complications.

In contrast, while conditions like stroke, cardiac arrest, and arrhythmia can be related to heart health, they are caused by different mechanisms. A stroke occurs when blood flow to the brain is interrupted, cardiac arrest is when the heart suddenly stops beating effectively, and arrhythmias are irregular heartbeats that can be caused by various factors but are not directly a result of blocked coronary arteries.
