Heart Disease Home > Diagnosing Heart Attacks
A heart attack is a life-threatening event. Diagnosing a heart attack early is vital to saving heart muscle. The longer the heart goes without oxygen and nutrients, the greater the damage will be and the higher the risk for sudden death.
Diagnosing heart attacks can begin once emergency medical personnel arrive after you call 911. Don't put off calling 911 just because you aren't sure if you are having a heart attack.
