Sudden death in young people — Heart problems often blamed
Can sudden death in young people be prevented?
It sometimes can. If you're found to be at high risk of sudden cardiac death, your doctor will usually suggest that you avoid competitive sports. Depending on your underlying condition, medical or surgical treatments may be recommended to reduce your risk of sudden death.
Another option for some, such as those with hypertrophic cardiomyopathy, is an implantable cardioverter-defibrillator (ICD). This is a pager-sized device implanted in your chest like a pacemaker. An ICD continuously monitors your heartbeat. If a life-threatening arrhythmia occurs, the ICD delivers electrical shocks to restore a normal heart rhythm.
Who should be screened for sudden death risk factors?
There's debate in the United States about screening young people at high risk of sudden death. Some countries, such as Italy and Japan, screen young people with the use of an electrocardiogram (ECG, or EKG), which records the electrical signals present in the heart. However, some scientists are concerned that this type of screening is expensive and turns up many false-positive results — indications that an abnormality or disease is present when in fact it is not.
There are some things you can do if you're worried about your risk factors. For example, if someone in your family dies young, it's important that an autopsy be done to determine the cause of death. If heart problems caused the death, all first-degree relatives of the deceased should be tested for heart problems that could cause sudden cardiac death — that means parents, siblings and children.
When sudden death in young people occurs, it often seems to happen in athletes. Does physical exertion increase the risk?
Yes. For many of these deaths, the trigger is often related to exercise.
If you're at risk of sudden cardiac death, talk to your doctor about your physical activity level. Whether you can participate in exercise or sports depends on your condition. For some disorders, such as hypertrophic cardiomyopathy, it's often recommended that you avoid most competitive sports, but this does not mean that you will need to avoid exercise altogether. Talk to your doctor about what sort of activities and behaviors you should avoid.
