Management of Obese Patients with Cardiovascular Disease with Emerging Weight-Lowering Drugs: A Narrative Review.
This narrative review examines emerging pharmacological approaches for managing obesity in patients with cardiovascular disease, with a focus on novel anti-obesity agents beyond the already-established semaglutide and tirzepatide. The authors surveyed the current landscape of investigational weight-lowering drugs, categorizing them by their primary mechanisms of action: reducing caloric intake, increasing basal metabolic rate, and increasing muscle mass. The review highlights that GLP-1 receptor agonists (GLP-1 RAs) have demonstrated both significant weight reduction and cardiovascular benefits, but notes a concern regarding muscle wasting associated with their use. The authors suggest that combination therapies using agents with complementary mechanisms may help mitigate this side effect. The review concludes that obesity treatment is likely to become more personalized over time and anticipates further cardiovascular benefits from pipeline agents. The authors also emphasize that the strongest evidence linking increased muscle mass and basal metabolic rate to improved cardiovascular health comes from diet and physical activity, positioning pharmacotherapy as a complement to—rather than a replacement for—healthy lifestyle changes. As a narrative review, this paper does not perform systematic synthesis or meta-analysis, and its conclusions reflect the authors' expert opinion rather than pooled quantitative data.
Why this grade: This is a narrative review summarizing existing literature and author opinion; it does not present original trial data or systematic evidence synthesis, limiting its independent evidentiary weight.
Background/Objectives : Obesity has a huge impact on global healthcare and economy. Consequently, the pharmaceutical industry has recently introduced novel anti-obesity drugs such as semaglutide and tirzepatide, which can yield remarkable weight reduction in patients, while also having significant cardiovascular benefits. Methods : Other weight-lowering medications are currently under investigation, and this narrative review provides an overview of the main novel drugs that are being tested. Results: These novel agents have different mechanisms of action, e.g., calorie intake reduction, increase in basal metabolism, and increase in muscle mass. Conclusions: In the future, obesity treatment is likely to become increasingly personalized, and further cardiovascular benefits could be expected. The combined use of different molecules could minimize their side effects, for instance, by minimizing muscle wasting observed during glucagon-like peptide 1 receptor agonists (GLP1-RAs) therapy. In our opinion, these highly effective drugs could represent a valuable addition to healthy lifestyle, as the evidence linking increases in muscle mass and basal metabolic rate to improved cardiovascular health is strongest when these changes are achieved through diet and regular physical activity.
