The chance of developing coronary heart disease can be reduced by taking steps to prevent and control factors that put people at greater risk. Additionally, knowing the signs and symptoms of heart attack are crucial to the most positive outcomes after having a heart attack.   

Other conditions that affect your heart or increase your risk of death or disability include arrhythmia, heart failure, and peripheral artery disease (PAD). High cholesterol, high blood pressure, obesity, diabetes, tobacco use, unhealthy diet, physical inactivity, and secondhand smoke are also risk factors associated with heart disease.

Know Your Signs and Symptoms

Some heart attacks are sudden and intense; however, most heart attacks start slowly, with mild pain or discomfort. Often people affected aren't sure what's wrong and wait too long before getting help.

Here are signs that can mean a heart attack is happening:

• Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness, or pain.
• Discomfort in other areas of the upper body. Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw, or stomach.
• Shortness of breath. May occur with or without chest discomfort.
• Other signs. These may include breaking out in a cold sweat, nausea, or lightheadedness.
