It has been well documented that aspirin reduces the risk of heart attack in
people with known coronary artery disease (CAD). It is also now understood that
aspirin lowers the risk of having symptoms for people who have a higher risk
for the disease. People who are at high risk for coronary artery disease or who
already have coronary artery disease benefit the most from aspirin therapy.
You can take aspirin to help you during a heart attack. After you call 911
or other emergency services, chew 1 adult-strength aspirin (325 mg) if you are
not allergic to aspirin and if there is no other reason that you can't take
aspirin. Aspirin slows blood clotting, so a blood clot that is causing the
heart attack stays smaller.
The most common symptom of coronary artery disease is angina, or chest pain. Angina can be described as a discomfort, heaviness, pressure, aching, burning, fullness, squeezing, or painful feeling in your chest. It can be mistaken for indigestion or heartburn. Angina may also be felt in the shoulders, arms, neck, throat, jaw, or back.
Other symptoms of coronary artery disease include:
Shortness of breath
Palpitations (irregular heart beats, or a "flip-flop" feeling in your chest)
During a heart attack, symptoms typically last 30 minutes or longer and are not relieved by rest or oral medications. Initial symptoms may start as a mild discomfort that progresses to significant pain.
Some people have a heart attack without having any symptoms, which is known as a "silent" myocardial infarction (MI). It occurs more often in people with diabetes.
If you think you are having a heart attack, DO NOT DELAY. Call for emergency help (dial 911 in most areas). Immediate treatment of a heart attack is very important to lessen the amount of damage to your heart.
Symptoms of Arrhythmias
When symptoms of arrhythmias, or an abnormal heart rhythm, are present, they may include:
Palpitations (a feeling of skipped heart beats, fluttering or "flip-flops" in your chest)
