Abstract

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.
