Angina is not a disease, but a symptom of heart problems. Generally, angina results when a clogged coronary artery restricts the flow of blood to your heart. The pain may feel like pressure or squeezing pain in your chest, like indigestion, or pain may occur in your shoulders, arms, neck, jaw or back.
The difference between angina and a heart attack is the blood flow. In angina, blood flow is temporarily reduced. In a heart attack, blood flow to the heart muscle is suddenly stopped and permanent damage occurs.
