Retrospective database query reveals significantly higher in-hospital mortality among patients with acute inferior wall myocardial infarction and right ventricular failure, highlighting poor outcomes.
Aim: Right ventricular failure (RVF) complicates 30–50% of cases with inferior wall myocardial infarctions (IWMI). Large-scale studies exploring the recent trends in morbidity and mortality of IWMI with RVF in the context of improved reperfusion strategies are currently lacking. Materials & methods: The International Classification of Diseases, Tenth Revision, Clinical Modification codes were used to query the National Inpatient Sample of 2018–2019 to yield IWMI admissions and stratified based on presence of RVF. The primary outcome was in-hospital mortality. Results: Out of the 182,485 weighed hospital admissions for IWMI, 1005 patients (0.6%) also had RVF. Patients with both IWMI and RVF had significantly higher mortality than patients with IWMI and no RVF (p < 0.001). Conclusion: RVF in patients with IWMI is an independent predictor of poor outcomes.
