Acute Coronary Syndrome


Acute coronary syndrome is any condition that causes a reduced blood flow to the heart, which in turn can cause a heart attack or unstable angina. The blockage can be sudden and complete, or it can come and go. But in either case, the heart tissue is dying, whether it’s a few cells or a big section of the heart.

The symptoms for both conditions are similar:

  • Chest pain or discomfort, which may involve pressure, tightness or fullness
  • Pain or discomfort in one or both arms, the jaw, neck, back or stomach
  • Shortness of breath
  • Feeling dizzy or lightheaded
  • Nausea
  • Sweating
  • Lightheadedness or sudden weakness
  • Fast or irregular heartbeat

Chest pain that comes on suddenly usually signals a heart attack. With unstable angine, the pain can be unpredictable or get worse, even with rest. 

If you experience these symptoms, take them seriously, and call 911 immediately.

Our goal is to quickly determine what's causing your symptoms. We'll perform an electrocardiogram, or EKG, to see if you're having a heart attack.

If blood flow to your heart is blocked, Mercy cardiologists will work swiftly to reopen your artery and dissolve any blood clots. Treatments may include medication, angioplasty or bypass surgery.
