What causes heart disease?

The causes of cardiovascular disease can vary depending on the specific type of cardiovascular disease. For example, atherosclerosis (plaque buildup in the arteries) causes coronary artery disease and peripheral artery disease. Coronary artery disease, scarring of the heart muscle, genetic problems or medications can cause arrhythmias. Aging, infections and rheumatic disease can cause valve disease.
