About one in four deaths in the United States are due to heart disease. But a new study suggests that exercise could combat that. Even if you have a genetic risk for heart disease.
In the study, researchers looked at data from nearly 500,000 people from England, Scotland and Wales.
The researchers found that overall, exercise lowered their risk of having heart problems over about six years. The researchers also found that among people with an elevated genetic risk for heart disease, having a strong grip (a measure of physical ability) lowered a person’s risk of coronary heart disease by 36% and their risk for atrial fibrillation (abnormal heartbeat) by 46% compared to men and women with weak grips.
For men and women at a high genetic risk for heart disease, high fitness levels was linked to a 49% lower risk for coronary heart disease and a 60% lower risk for atrial fibrillation.
