A recent study suggests that individuals with stronger chest, back, and torso muscles may face a lower risk of heart attacks and reduced mortality over the following decade. Researchers analyzing muscle strength and cardiovascular outcomes found a significant association between muscle density and cardiovascular health.

The study, published in the journal Radiology, involved an AI-driven examination of imaging data from 1,722 participants in the Scottish Computed Tomography of the Heart (SCOT-HEART) trial. The images allowed researchers to assess the muscle mass of each patient, focusing on the pectoral and back muscles.

Findings indicated that patients with below-average muscle density had notably higher risks. Specifically, they showed an 85% increased risk of death and a 58% higher likelihood of experiencing a heart attack during the study’s follow-up period compared to those with greater muscle mass.

Professor Bryan Williams, chief scientific and medical officer at the British Heart Foundation, commented on the results, highlighting the probable link between muscle density and physical activity. He noted that individuals with stronger muscles were likely more active, which in turn contributes to improved heart health. He emphasized the study as further evidence reinforcing the benefits of regular exercise in reducing cardiovascular risk.

The study adds to growing research on the positive impact of muscle health and physical fitness on cardiovascular outcomes. While the exact mechanisms are still being explored, maintaining muscle strength through consistent physical activity appears to be a valuable strategy for protecting the heart and enhancing overall longevity.
