What is the impact of mitral annular calcification on cardiovascular events?
Mitral annular calcification (MAC) is a form of heart valve disease that occurs when calcium deposits form around the annulus of the mitral valve. Studies have found that MAC is associated with an increased risk of cardiovascular events, such as stroke, heart attack, heart failure, and arrhythmias. In a multiethnic community study, researchers found that MAC was associated with a nearly three-fold increase in the risk of stroke. Other studies have also found an association between MAC and increased risk of stroke and other cardiovascular events, although the exact mechanism by which MAC increases risk is not yet fully understood. Treatment for MAC typically involves lifestyle changes and medications, depending on the severity of the condition.
