Sudden Cardiac Death
Can Sudden Cardiac Death Be Prevented?
If you have any of the above listed risk factors for sudden cardiac death, it is important that you speak with your doctor about possible steps to reduce your risk.
Keeping regular follow-up appointments with your doctor, making certain lifestyle changes, taking medications as prescribed, and having interventional procedures or surgery (as recommended) are ways you can reduce your risk.
Follow-up Care with Your Doctor: Your doctor will tell you how often you need to have follow-up visits. To prevent future episodes of sudden cardiac arrest, your doctor will want to perform diagnostic tests to determine what caused the cardiac event. Tests may include electrocardiogram (ECG or EKG), ambulatory monitoring, echocardiogram, cardiac catheterization, and electrophysiology studies.
Ejection Fraction (EF): EF is a measurement of the percentage of blood pumped out of the heart with each beat. EF can be measured in your doctor’s office during an echocardiogram (echo) or during other tests such as a MUGA (multiple gated acquisition) scan, cardiac catheterization, nuclear stress test, or magnetic resonance imaging (MRI) scan of the heart. The EF of a healthy heart ranges from 55 to 65 percent. Your EF can go up and down, based on your heart condition and the effectiveness of the therapies that have been prescribed. If you have heart disease, it is important to have your EF measured initially, and then as needed, based on changes in your condition. Ask your doctor how often you should have your EF checked.
Reducing your risk factors: If you have coronary artery disease — and even if you do not — there are certain lifestyle changes you can make to reduce your risk of sudden cardiac arrest. These lifestyle changes include:
- Quitting smoking
- Losing weight
- Exercising regularly
- Following a low-fat diet
- Managing diabetes
- Managing other health conditions including high blood pressure and cholesterol
If you have questions or are unsure how make these changes, talk to your doctor. Patients and families should know the signs and symptoms of coronary artery disease and the steps to take if symptoms occur.
