Basic symptoms of heart attack include chest tightness or pressure and/or pain in the chest, neck, jaw, arms or back.
When you're having a heart attack, every second counts. The longer the heart blockage remains untreated, the more heart muscle can die. Drugs that break down blockages must be administered in the first hours after a heart attack to be successful and minimize lasting damage.
If you are at risk for heart disease or have any of these symptoms, seek medical attention or call 9-1-1 immediately.
