Abstract Background Sodium-glucose cotransporter 2 inhibitors (SGLT2-Is) have emerged as a vital component in the management of heart failure (HF), demonstrating significant improvements in cardiac function. However, their impact on outcomes in patients with acute myocardial infarction (AMI) remains poorly characterized. This study aimed to evaluate the long-term outcomes of SGLT2-Is among patients with AMI. Methods We conducted a retrospective cohort study using data from the TriNetX Banner Health Network platform in the United States, including patients aged ≥18 years with AMI identified through ICD-10 codes. Patients were categorized into two cohorts based on SGLT2-I use. Propensity score matching (PSM) was performed to balance baseline demographics, comorbidities (e.g., hypertension, diabetes, chronic kidney disease, heart failure, and hyperlipidemia), and medication use (e.g., heart failure therapies, antiplatelet agents, anticoagulants). Risk ratios (RRs) and 95% confidence intervals (95% CIs) were estimated for the following cardiovascular outcomes: acute HF hospitalizations, stroke, all-cause hospitalizations, recurrent AMI, cardiac arrest, and new-onset atrial fibrillation (AF). Kaplan-Meier analysis was completed to estimate survival probability from all-cause hospitalizations. Results After PSM, 2,440 patients were analyzed (1,220 SGLT2-I users; 1,220 non-users). Both cohorts had similar characteristics without any residual imbalance: mean age 67.7 years in the SGLT2-I group vs. 67.5 years in non-users, and both groups included 85.2% White and 33.6% female patients. Mean follow-up duration was 608 days for SGLT2-I users and 1,013.5 days for non-users. SGLT2-I use was associated with significantly lower rates of all-cause hospitalizations (RR: 0.712; 95% CI: 0.652–0.777), HF-related hospitalizations (RR: 0.878; 95% CI: 0.781–0.987), recurrent AMI (RR: 0.821; 95% CI: 0.703–0.959), and cardiac arrest (RR: 0.500; 95% CI: 0.345–0.725). No significant differences were observed in stroke (RR: 0.909; 95% CI: 0.702–1.178) or new-onset AF (RR: 0.889; 95% CI: 0.782–1.010) between the cohorts. Conclusions SGLT2-Is are associated with improved cardiovascular outcomes in patients with AMI, including reductions in all-cause and HF-related hospitalizations, recurrent AMI, and cardiac arrest. While these findings are hypothesis-generating, they emphasize the need for prospective clinical trials to confirm these results.Kaplan-Meier Analysis.
