Silent heart attack: What are the risks?
Medically reviewed on April 25, 2017
A silent heart attack is a heart attack that has few, if any, symptoms. You may have never had any symptoms to warn you that you've developed a heart problem, such as chest pain or shortness of breath. Some people later recall their silent heart attack was mistaken for indigestion, nausea, muscle pain or a bad case of the flu.
The risk factors for a silent heart attack are the same as those for a heart attack with symptoms. The risk factors include:
- Smoking or chewing tobacco
- Family history of heart disease
- High cholesterol
- High blood pressure
- Lack of exercise
- Being overweight
Having a silent heart attack puts you at a greater risk of having another heart attack, which could be fatal. Having another heart attack also increases your risk of complications, such as heart failure.
There are no tests to determine your potential for having a silent heart attack, but if you have the risk factors, they should be evaluated by your doctor and treated to reduce your likelihood for having a silent heart attack. The only way to tell if you've had a silent heart attack is to have imaging tests, such as an electrocardiogram, echocardiogram or others. These tests can reveal changes that signal you've had a heart attack.
If you wonder if you've had a silent heart attack, talk to your doctor. A review of your symptoms, health history and a physical exam can help your doctor decide if more tests are necessary.
