Which of the following is a feature of cardiovascular disease?

Coronary heart disease is a feature of cardiovascular disease because it specifically relates to the health of the heart and blood vessels. Cardiovascular disease encompasses a range of disorders affecting the heart and the circulation system, and coronary heart disease is one of the most common forms. It occurs when the coronary arteries become narrowed or blocked, reducing blood flow to the heart muscle and potentially leading to events such as heart attacks. Understanding coronary heart disease is critical in the study of cardiovascular health, as it illustrates the importance of factors like diet, exercise, and genetics on heart health. The other options represent different health conditions that do not fall within the definition of cardiovascular disease, highlighting the unique characteristics and implications of coronary heart disease within the broader category of cardiovascular issues.
