Acute Coronary Syndrome

Immediate treatment can help prevent a heart attack.

JoAnne M. Foody, MD, FACC, CardioSmart Editor-in-Chief

Know the symptoms

Your heart muscle needs oxygen and nutrients to work the way it should.

If the arteries supplying the heart (called the coronary arteries) become narrowed or blocked, the heart muscle can be starved of oxygen-rich blood. If this happens very suddenly, as is the case with heart attack, it can be very serious.

Acute coronary syndrome is a medical term used to describe problems that occur when there isn’t enough blood flow to the heart. Heart attack and unstable angina (sudden chest pain that typically occurs when someone is at rest) are two examples. 

If you are having a heart attack, you might feel pain or pressure in your chest; have shortness of breath; feel nauseated or have discomfort in one or both arms, the back, neck, jaw or stomach. Dial 9-1-1 right away. Time is muscle. Every second you delay means more damage to your heart—it could also be the difference between life and death. 

The treatment you receive will depend on your symptoms and test results that can show how much your arteries are blocked. There are many things you can do to protect your future heart health. Use this condition center to learn more about acute coronary syndromes. You can keep up with the latest research, find questions to ask your doctor, and get tips to help you feel your best.
