Abstract
Introduction: In the US, there are approximately 84 million cases of COVID-19 accounting for 1 million deaths. Though there are not many studies, acute myocardial infarction (AMI) is one of the most lethal complications of COVID-19. In this study, we looked for occurrence of AMI and its effects on hospital outcomes among COVID-19 patients. Hypothesis: AMI among COVID-19 hospitalizations could worsen the levels of adverse in-hospital outcomes. Methods: Data from the 2020 California State Inpatient Database was used retrospectively. All COVID-19 hospitalizations with age ≥18 years were included in the analyses. Adverse hospital outcomes included in-hospital mortality, prolonged length of stay, vasopressor use, mechanical ventilation, and ICU admission. Prolonged length of stay included any hospital length of stay ≥75th percentile. We explored for differences in adverse hospital outcomes between those with and without AMI. Multivariate logistic regression analyses were used to understand the strength of these associations after adjusting for cofactors. Results: Our analysis had a total of 94,114 COVID-19 hospitalizations and 1548 (1.6%) had AMI. Adverse hospital outcomes such as mortality (43.2% versus 10.8%, P<0.001), prolonged length of stay (39.9% versus 28.2%, P<0.001), vasopressor use (7.8% versus 2.1%, P<0.001), mechanical ventilation (35.0% versus 9.7%, P<0.001), and ICU admission (33.0% versus 9.4%, P<0.001) were significantly higher among COVID-19 hospitalizations with AMI. The odds of adverse outcomes such as mortality (aOR, 3.90, 95% CI: 3.48-4.36), prolonged length of stay (aOR, 1.23, 95% CI: 1.10-1.37), vasopressor use (aOR, 3.71, 95% CI: 3.30-4.17), mechanical ventilation (aOR, 2.71, 95% CI: 2.21-3.32), and ICU admission (aOR, 3.51, 95% CI: 3.12-3.96) were significantly more prevalent among COVID-19 hospitalizations with AMI. Conclusions: In spite of very low prevalence of AMI among COVID-19 hospitalizations, we observed a substantially greater risk of adverse hospital outcomes and mortality. The hyperinflammatory response of COVID-19 could additionally worsen the factors precipitating mortality among AMI. COVID-19 patients with AMI should be aggressively treated to improve hospital outcomes.
