Final answer:
Coronary sinus dilation is caused by restricted blood flow in the coronary arteries due to plaque buildup. It is a response to maintain sufficient blood flow to the heart muscle. Severe plaque buildup can lead to reduced or blocked blood flow buildup becomes severe.
Step-by-step explanation:
Coronary sinus dilation is typically caused by restricted blood flow in the coronary arteries due to plaque buildup, also known as atherosclerosis. As plaque accumulates in the arteries, the walls of the artery dilate in an attempt to maintain sufficient blood flow to the heart muscle. However, if the plaque buildup becomes severe, it can lead to reduced or blocked blood flow, which can result in chest pain or a heart attack.
