Abstract: Objectives While the interaction between heart and kidney potentially contributes the development of renal hyperfiltration (RHF), its clinical consequence of is not clear in patients with acute myocardial infarction (AMI). Methods A total of 9,561 AMI patients with estimated GFR (eGFR) ≥60 mL/min/1.73 m² were enrolled from a large nationwide, multi-center, prospective, observational cohort between November 2011 and December 2015. RHF was defined as eGFR >90th percentile after multiple adjustments. The primary endpoint was a combination of 3-year major adverse cardiovascular events (MACEs) after AMI treatment. Results The cumulative event rate of MACEs was significantly higher in patients with RHF. In multivariable Cox-regression analysis, RHF increased the 1.34-fold risk of MACE (95% confidence interval [CI] 1.12-1.62) compared to those without RHF. Patients with RHF had a significantly higher risk of all-cause mortality (hazard ratio [HR] 1.64; 95% CI 1.25-2.14) and cardiac death (HR 1.78; 95% CI 1.26-2.51). There was a linear correlation between the adjusted risk of MACEs and eGFR, with the risk increasing as eGFR exceeded approximately 100 mL/min/1.73 m². In the 1:1 propensity-score matched population, the cumulative event rate of MACEs, all-cause mortality, and cardiac death were consistently higher in patients with RHF (all p <0.05). Conclusion RHF was significantly associated with an increased risk of MACEs, all-cause mortality, and cardiac death following AMI compared to patients without RHF. Our study offers new insights into the risk stratification of AMI patients presenting with RHF.
