    BackgroundThere are limited data on the outcomes of cardiogenic shock (CS) and cardiac arrest (CA) complicating ST-segment-elevation myocardial infarction (STEMI).MethodsAdult (>18 years) STEMI admissions were identified using the National Inpatient Sample (2000-2017) and classified as CS + CA, CS only, CA only and no CS/CA. Outcomes of interest included temporal trends, in-hospital mortality, hospitalization costs, use of do-not-resuscitate (DNR) status and palliative care referrals across the four cohorts.ResultsOf the 4,320,117 STEMI admissions, CS, CA and both were noted in 5.8%, 6.2% and 2.7%, respectively. In 2017, compared to 2000, there was an increase in CA (adjusted odds ratio [aOR] 1.83 [95% confidence interval {CI} 1.79-1.86]), CS (aOR 3.92 [95% CI 3.84-4.01]) and both (aOR 4.09 [95% CI 3.94-4.24]) (all p < 0.001). The CS+CA (77.2%) cohort had higher rates of multiorgan failure than CS only (59.7%) and CA only (26.3%), p < 0.001. The CA only cohort had lower rates (64%) of coronary angiography compared to the other groups (>70%), p < 0.001. In-hospital mortality was higher in CS+CA compared to CS alone (adjusted OR 1.87 [95% CI 1.83-1.91]), CA alone (adjusted OR 1.99 [95% CI 1.95-2.03]) or neither (aOR 18.37 [95% CI 18.02-18.71]). The CS+CA cohort had higher use of palliative care and DNR status. The presence of CS, either alone or in combination with CA, was associated with higher hospitalization costs.ConclusionsThe combination of CS and CA was associated with higher rates of non-cardiac organ failure and in-hospital mortality in STEMI compared to those with either CS or CA alone.Copyright © 2020 Elsevier B.V.
