Drs. Karl and Spencer discuss how semaglutide impacts the heart with new trial data available. Learn how semaglutide may reduce risks of heart attacks and also how it impacts your quality of life if you have heart failure.
Semaglutide, a GLP-1 receptor agonist, reduces the risk of heart attacks in high-risk individuals with type 2 diabetes and cardiovascular disease.
Semaglutide, a GLP-1 receptor agonist, improves quality of life, exercise tolerance, and weight reduction in obese individuals with heart failure and preserved ejection fraction.

Benefits of GLP1 receptor agonists in high-risk individuals
GLP1 receptor agonists, such as somaglutide ozemic, have shown to reduce the risk of cardiovascular events in patients with type 2 diabetes and high risk for cardiovascular disease. Despite the slight increase in heart rate observed with these medications, the overall benefits are significant. The average pulse increase is only 2 beats per minute, which is not concerning. These medications have been used for 15 years and have consistently shown positive results in cardiovascular outcome trials. These findings provide reassurance regarding the safety and efficacy of GLP1 receptor agonists in high-risk individuals.
GLP1 receptor agonists for heart failure patients
GLP1 receptor agonists, specifically somaglutide, have shown promising results in patients with heart failure, particularly in those with half-peff (heart failure with preserved ejection fraction) and obesity. The select trial, which focused on 529 patients with half-peff heart failure, demonstrated that somaglutide led to significant improvements in quality of life scores, six-minute walking distance, and weight reduction. The weight loss achieved with somaglutide contributed to the overall improvement in cardiovascular health and exercise tolerance. These findings highlight the potential benefits of GLP1 receptor agonists in treating heart failure among obese individuals.
Reduced risk of arrhythmias with GLP1 receptor agonists
Contrary to concerns about increased heart rate as a side effect of GLP1 receptor agonists, studies indicate that these medications may actually reduce the risk of arrhythmias, particularly atrial fibrillation, in high-risk patients with obesity and type 2 diabetes. One meta-analysis found that GLP1 receptor agonists were associated with a decreased risk of atrial arrhythmias, further supporting their positive impact on cardiovascular health. While more research is needed to fully understand the mechanisms behind these benefits, the weight reduction achieved with GLP1 receptor agonists likely plays a significant role in improving heart rhythm and overall cardiac function.
