Most active older adults probably should not worry about having sudden cardiac arrest—when the heart suddenly and unexpectedly stops beating — while they're exercising or participating in sports, according to a study published online Jan. 18, 2023, by JACC: Clinical Electrophysiology.
Investigators analyzed the medical information of 1.85 million people over 15 years from two major metropolitan areas. They found that of the approximately 4,000 cases of sudden cardiac arrest among adults ages 65 and older, only about 2% to 3% occurred during or following an activity, such as cycling, a gym workout, running, or playing golf or tennis. However, a vast majority of the cardiac arrests did occur in men.
The study also found that among everyone who had sudden cardiac arrest, those who suffered an attack during or shortly after playing sports or exercising were less likely to have previously identified heart disease risk factors. Because such a small number of active older adults were affected, the researchers concluded the benefits of exercise and sports likely outweigh any risks. Even so, it's recommended that older adults check with their doctor before embarking on any new exercise program, especially if they have high blood pressure or high cholesterol. Also, people should always seek immediate medical care if they experience any symptoms while active, like shortness of breath and chest pain.
