Effects of statins on outcomes in Hispanic patients with COVID-19

The Hispanic population is regarded among those who are at greater risk of adverse prognoses due to higher rates of diabetes and obesity in the USA during the COVID-19 pandemic. Statin medications are speculated to help treat the infection by decreasing inflammation caused by COVID-19. In this retrospective, observational study, outcomes of statin use were assessed among Hispanic patients with COVID-19 by screening all patients hospitalized between March, 2020 and March, 2021 at a tertiary care hospital in El Paso, Texas, resulting in a total of 1039 patients. The patients were categorized into a group of either being on statins or not. The considered outcomes were mechanical ventilation, intensive care unit (ICU) hospitalization, oxygen supplementation at discharge, hospital length of stay, and mortality. Patients receiving statins were observed to be older with more comorbidities. In the propensity-scores adjusted analysis, no association was found between statin use and: mortality (adjusted risk ratio (aRR)=0.96, p=0.754), mechanical ventilation (aRR=0.91, p=0.503), ICU transfer (aRR=0.96, p=0.395), and O₂ supplementation at discharge (aRR=1.03, p=0.729). These outcomes were also evaluated in patients who had myocardial infarction and stroke with COVID-19. Among these patients, association was found between statin use and: a reduced risk of mortality (aRR=0.61, p=0.005), mechanical ventilation (aRR=0.53, p=0.012) and ICU transfers (aRR=0.81, p=0.005). These results may not give us a reason to start patients on statins for the specific treatment of COVID-19, but it may be sufficient evidence to suggest statins should not be discontinued during hospitalization due to COVID-19.
