Every 40 seconds, someone in the United States suffers a heart attack. A heart attack is caused by a blood clot that blocks a coronary artery. The coronary arteries supply blood and oxygen to the heart. If the blood flow is blocked, the heart is deprived of oxygen and heart muscle dies.
The medical term for a heart attack is myocardial infarction.
A heart attack occurs when:
Heart attacks can occur when resting or asleep, after a sudden increase in physical activity, when active outside in cold weather, or after severe stress or illness.
Chest pain is the most common symptom of a heart attack and may be felt in only one part of the body or may move from the chest to the arms, shoulders, neck, teeth, jaw, stomach, or back.
The pain can be severe or mild, and often feels like a tight band around the chest, bad indigestion, something sitting on the chest, or squeezing or heavy pressure.
Other symptoms of a heart attack can include:
Some people have little or no chest pain. Or, they may have unusual symptoms such as shortness of breath, fatigue, and weakness. A “silent heart attack” is a heart attack without symptoms.

A blood test can also show evidence of heart tissue damage.
By participating in this quiz, or screening or health assessment, I recognize and accept all risks associated with it. I understand that the program will only screen for certain risk factors and does not constitute a complete physical exam. For the diagnosis of a medical problem, I must see a physician for a complete medical exam. I release Deborah Heart and Lung Center and any other organization(s) involved in this screening, and their employees and agents, from all liabilities, medical claims or expenses which may arise from my participation.
