A recent study suggests that weight loss injections may reduce the risk of heart attack or stroke, regardless of the amount of weight lost. Researchers found that targeting belly fat is crucial for enhancing heart health, as opposed to overall weight loss, which can involve muscle mass reduction. The study, led by Professor John Deanfield from University College London, highlighted the significance of abdominal fat in cardiovascular health.
The research focused on 17,604 individuals using the drug semaglutide, known as Wegovy for obesity and Ozempic for diabetes. Participants aged 45 or older, who were overweight or obese, were monitored for major adverse cardiac events such as heart disease death, heart attack, or stroke. The study, conducted across 41 countries, revealed that semaglutide decreased the risk of these events by 20%, irrespective of the weight loss achieved.
Interestingly, the cardiovascular benefits of semaglutide were observed in participants with varying body mass index (BMI) scores, suggesting that even those with average BMI could experience positive effects. The research also indicated that the drug’s impact on heart health was not solely dependent on weight loss, with waist circumference reduction playing a significant role in improving cardiovascular outcomes.
Prof Deanfield emphasized the importance of considering semaglutide for a broader population, rather than limiting its usage to severely obese individuals. The study’s findings suggest that the drug’s benefits extend beyond weight loss, potentially affecting heart disease and age-related conditions. As the NHS plans to provide weight loss injections to 240,000 people in England, experts like Prof Tim Chico from Sheffield University advocate for broader adoption of semaglutide to enhance heart health.
Dr Sonya Babu-Narayan of the British Heart Foundation underscored the need for further research to elucidate the additional mechanisms through which medications like semaglutide benefit heart health. While acknowledging the cardiovascular advantages of such drugs, she emphasized the importance of maintaining a healthy lifestyle, including regular physical activity and a nutritious diet, to optimize long-term heart health.
In conclusion, the study’s findings suggest that weight loss injections like semaglutide offer significant cardiovascular benefits beyond just shedding pounds, indicating a potential shift in the approach to heart disease management.
