ABSTRACT
Heart failure (HF) stands as a formidable challenge in global healthcare casting a long shadow over both morbidity and mortality. A significant interplay between HF and type 2 diabetes (T2DM) manifests an elevated risk of adverse cardiovascular events in T2DM patients. Glucagon-like peptide 1 emerges as a pivotal player in T2DM, which is released in response to meals rich in glucose and lipids. We aim to assess the outcomes of using semaglutide in HF. A comprehensive literature search was performed using electronic databases, including PubMed/Medline, the Cochrane Library, and Google Scholar, covering all records up to May 10, 2024. Studies meeting inclusion criteria were selected. Qualitative analysis was conducted to analyze the findings of the studies included. Four studies (three randomized controlled trials and one observational study) were included in our manuscript. There was a significant decrease in the Kansas City Cardiomyopathy Questionnaire clinical summary score (p< 0.001), body weight (p< 0.001), six-minute walk distance (p< 0.001), and CRP levels (p< 0.001). A statistically significant decrease in overall major adverse cardiac events was observed with a hazard ratio of 0.76 (95% CI 0.62, 0.92). Other factors and adverse effects were also discussed in our manuscript. Our study showed that semaglutide resulted in improvement in HF patients. Although adverse effects were observed, they were not as significant as the placebo itself.
