Cardiovascular disease is an abnormal function of the heart or blood vessels that is caused by a buildup of fatty plaques in the arteries over time. This restricts blood flow and increases the risk of heart attack, heart failure, stroke, and other cardiac issues. Treatments include lifestyle changes, medication, or procedures like surgery to reopen blocked arteries using a catheter and balloon. Preventing cardiovascular disease involves quitting smoking, regular exercise, a healthy diet, stress management, sufficient sleep, and regular health screenings.
