Key result
Right ventricular infarction with dysfunction is linked to 25% in-hospital mortality versus no RV involvement.
Why the study?
Inferior wall myocardial infarction is generally considered low risk compared to anterior infarction, prompting evaluation of the prognostic impact of right ventricular myocardial involvement.
Does right ventricular dysfunction increase in-hospital morbidity and mortality in patients with inferior wall myocardial infarction?
Observational (n=82)
No
Does right ventricular dysfunction increase in-hospital morbidity and mortality in patients with inferior wall myocardial infarction?
Absolute Event Rate: 25% vs 0%
p-value: p=<0.001
Right ventricular dysfunction is a significant independent predictor of in-hospital mortality in patients presenting with inferior wall myocardial infarction.
RV involvement signals higher mortality risk in inferior MI; hypothesis-generating for targeted strategies pending prospective validation.

Shakya et al. (2023) conducted an observational in Inferior Wall Myocardial Infarction (n=82). Right ventricular myocardial infarction vs. No right ventricular myocardial infarction was evaluated on In-hospital mortality (p=<0.001). Right ventricular myocardial infarction with dysfunction was associated with significantly higher in-hospital mortality compared to no right ventricular involvement (25% vs 0%, p<0.001).
