Angina is chest pain or discomfort that occurs when your heart muscle doesn't get enough blood. It's a symptom of coronary artery disease, the most common type of heart disease.

The coronary arteries bring blood to the heart muscle; if they get clogged, a heart attack can occur. Heart disease is largely considered a man's disease. In reality, heart disease is the No. 1 killer of American women, striking 1 in 3 at age 65 or older.

The symptoms of heart attack in women are subtle in many cases. Crushing chest pain – the hallmark of a heart attack in men – often isn't experienced by women. It's crucial to know what signs to look for and what to do if you are at risk for heart attack.
