Heart disease is the leading cause of death for both men and women. The most common type is coronary artery disease, which can cause heart attacks, angina, heart failure, and arrhythmias. Coronary artery disease occurs when plaque builds up in the arteries that supply blood to the heart and the arteries narrow (atherosclerosis). Angina may feel like pressure or a squeezing pain in the chest. The pain also may occur in the shoulders, arms, neck, jaw, or back. It may feel like indigestion.  A heart attack, also called a myocardial infarction, occurs when a part of the heart muscle doesn’t receive enough blood flow. The more time that passes without treatment to restore blood flow, the greater the damage to the heart muscle. Every year, about 735,000 Americans have a heart attack. Of these cases 525,000 are a first heart attack and 210,000 happen to people who have already had a first heart attack. If you’ve had a heart attack, your heart may be damaged. This could affect your heart’s rhythm, pumping action, and blood circulation. You also may be at risk for another heart attack or conditions such as stroke, kidney disorders, and peripheral arterial disease.
