Abstract

Myocardial ischemia is a known complication of HCM. Contemporary outcomes and care processes after STEMI are extensively examined; however, there are limited data on outcomes, and revascularization strategies of HCM patients with STEMI. The National Inpatient Sample 2004-2018 was queried to identify adult patients presenting with a primary diagnosis of STEMI, of whom a subset of patients with concomitant diagnosis of HCM were identified. Complex samples multivariable logistic and linear regression models were used to determine the association of HCM with in-hospital outcomes. HCM patients with STEMI who were revascularized were compared with their counterparts who were not revascularized. Of 3,049,068 primary STEMI hospitalizations, 2583 (0.8%) had an associated diagnosis of HCM. HCM patients were more likely to be elderly and female with less traditional cardiovascular risk factors compared to those without HCM. HCM patients were less likely to receive revascularization compared to those without HCM. STEMI with HCM was associated with similar in-hospital mortality (adjusted odds ratio [aOR] 1.09; 95% confidence interval [CI] 0.82-1.44; P = 0.561) compared to those without HCM. Notably, HCM patients who were revascularized had similar in-hospital mortality (aOR 0.69; 95% CI 0.36-1.33; P = 0.266) compared to HCM patients who did not receive revascularization. Despite lower rates of revascularization, STEMI in patients with HCM is associated with similar in-hospital mortality compared to those without HCM.
