Final answer:
Cardiovascular disease (CVD) includes major diseases like coronary artery disease and stroke, often caused by atherosclerosis. CAD can lead to angina or myocardial infarctions, while stroke involves the blood vessels in the brain.
Step-by-step explanation:
Cardiovascular disease (CVD) comprises a group of disorders affecting the heart and blood vessels. Two major diseases within this class are coronary artery disease (CAD), including conditions such as angina and myocardial infarction (heart attack), and stroke. Other CVDs include heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, abnormal heart rhythms, congenital heart disease, and many more. The leading cause of CVD is atherosclerosis, which is a buildup of plaque in the arteries that can lead to obstruction of blood flow. Treatment and prevention of hypertension and atherosclerosis are crucial in managing CVD.
