ABSTRACT
BACKGROUND: Our prior analysis demonstrated no significant difference in risk of mortality or disease progression among patients with COVID-19. With the availability of findings from randomized controlled trials (RCTs), we provide an updated review of RCTs which explored the outcomes among hospitalized patients with COVID-19 treated with Angiotensin Converting Enzyme inhibitor (ACEis)/Angiotensin Receptor Blockers (ARBs) versus control. RESEARCH DESIGN AND METHODS: This systematic review and meta-analysis covers RCTs exploring mortality, intensive care unit admission, and mechanical ventilation outcomes among hospitalized COVID-19 patients treated with ACEi/ARBs. RESULTS: Ten studies were included in this meta-analysis. For mortality with ACEi/ARB utilization among hospitalized COVID-19 patients, the pooled risk ratio (RR) was 0.97 (95% CI 0.64-1.47, p = 0.89) with heterogeneity of 26%. Further, the pooled RR for ACEi/ARB use on ICU admission and mechanical ventilation were 0.55 (0.55-1.08, p = 0.13) with a heterogeneity of 0% and 1.02 (0.78-1.32, p = 0.91) with a heterogeneity of 0%, respectively. CONCLUSION: Among hospitalized patients with COVID-19, the use of ACEi/ARB was not associated with increased risk of mortality, ICU admission, or mechanical ventilation compared to control. These findings support continuation of ACEi/ARB for whom baseline clinical indications for these agents exist.
