What major consequence can triglycerides in coronary arteries lead to?

Triglycerides are a type of fat found in the blood, and elevated levels can significantly contribute to the development of cardiovascular diseases. When triglycerides accumulate in coronary arteries, they lead to the formation of atherosclerotic plaques, narrowing the arteries and reducing blood flow to the heart muscle. This process can ultimately culminate in a heart attack (myocardial infarction), where the blood supply to part of the heart is obstructed, resulting in damage to heart tissue.

The impact of high triglyceride levels is particularly critical in the context of heart health, as they not only promote atherosclerosis but can also influence other risk factors for coronary artery disease, such as hypertension and insulin resistance. Therefore, among the choices provided, the direct consequence of elevated triglycerides in the coronary arteries is best described as a heart attack, making it the correct answer in this context.
