When you have a heart attack without any signs or symptoms, it’s called a silent heart attack. You may not even realize you’ve had a heart attack until your doctor discovers heart damage days or weeks later.
Most people mistake silent heart attack symptoms with indigestion, nausea, muscle pain or the flu. Some people face a higher-than-average risk of having a silent heart attack, and their risk factors include:
Age
Diabetes
Excessive Weight or Obesity
Family History of Heart Disease
High Blood Pressure
High Cholesterol
Lack of Exercise
Tobacco Use
