Cardiovascular disease (CVD) may be a class of diseases that involve the guts or blood vessels. CVD includes arteria coronaria diseases like angina and myocardial infarct (commonly referred to as a heart attack) Other CVDs include stroke, coronary failure, a hypertensive heart condition, rheumatic heart condition, cardiomyopathy, abnormal heart rhythms, a congenital heart condition, valvular heart condition, carditis, aortic aneurysms, peripheral artery disease, thromboembolic disease, and phlebothrombosis. The underlying mechanisms vary depending on the disease. Coronary artery disease, stroke, and peripheral artery disease involve atherosclerosis. This may be caused by high vital sign, smoking, DM, lack of exercise, obesity, high blood cholesterol, poor diet, and excessive alcohol consumption, among others. The high vital sign is estimated to account for about 13% of CVD deaths, while tobacco accounts for 9%, diabetes 6%, lack of exercise 6%, and obesity 5%. Rheumatic heart disease may follow untreated strep throat.
