ABSTRACTBackgroundPatients with cardiovascular disease are at increased risk of critical illness and mortality from Covid-19 disease. Conflicting findings have raised concerns regarding the association of angiotensin converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARBs) use with likelihood or severity of infection during this pandemic.ObjectiveTo study the cumulative evidence for association of ACEI/ARB use with outcomes among patients with confirmed Covid-19.MethodsThe MEDLINE and EMBASE databases were thoroughly searched from November 01, 2019 to May 15, 2020 for studies reporting on outcomes based on ACEI/ARB use in patients with confirmed Covid-19. Preferred reporting items for systematic review and meta-analysis guidelines were used for the present study. Relevant data was collected and pooled odds ratios (OR) with 95% confidence intervals (CI) were calculated using random-effects model.Main Outcome measuresIn-hospital mortality was the primary end of interest. Second end-point was severe or critical illness defined as either need for intensive care unit, invasive mechanical ventilation, or mortality.ResultsFifteen studies with total of 23,822 patients (N ACEI/ARB=6,650) were included in the present analysis. Overall, prevalence of ACEI/ARB use ranged from 7.7% to 46.2% across studies. Among 10 studies, patients using ACEI/ARB had similar odds of mortality [OR 1.03 (0.69-1.55)] and severe or critical illness [1.18 (0.91-1.54)] compared to those not on ACEI/ARB. In an analysis restricted to patients with hypertension, ACEI/ARB use was associated with significantly lower mortality [0.64 (0.45-0.89)], while the odds of severe/critical illness [0.76(0.52-1.12); p=0.16] remained non-significant compared with non-ACEI/ARB users.ConclusionThere is no evidence for increased risk of severe illness or mortality in patients using ACEI/ARB compared with non-users. In patients with hypertension, ACE/ARB use might be associated with reduced mortality, however these findings need to be confirmed in prospective randomized controlled trials.

Gastrointestinal bleeding (GIB) especially from arteriovenous malformations (AVM) remains one of the devastating complications following continuous-flow left ventricular device (CF-LVAD) implantation. Blockade of angiotensin II pathway using angiotensin-converting enzyme inhibitors (ACEI)/angiotensin receptor blockers (ARB) was reported to mitigate the risk of GIB and AVM-related GIB by suppressing angiogenesis. We performed a systematic review and meta-analysis to evaluate the association between ACEI/ARB treatment and GIB in CF-LVAD population. Comprehensive literature search was performed through December 2019. We included studies reporting risk of GIB and/or AVM-related GIB events in LVAD patients who received ACEI/ARB with those who did not. Data from each study were combined using the random-effects to calculate odd ratios and 95% confidence intervals. Three retrospective cohort studies were included in this meta-analysis involving 619 LVADs patients (467 patients receiving ACEI/ARB). The use of ACEI/ARB was statistically associated with decreased incidence of overall GIB (pooled OR 0.35, 95% CI 0.22–0.56, I2 = 0.0%, p < 0.001). There was a non-significant trend toward lower risk for AVM-related GIB in patients who received ACEI/ARB (pooled OR 0.46, 95% CI 0.19–1.07, I2 = 51%, p = 0.07). Larger studies with specific definitions of ACEI/ARB use and GIB are warranted to accurately determine the potential non-hemodynamic benefits of ACEI/ARB in CF-LVAD patients.

The use of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin-receptor blockers (ARBs) in patients with Coronavirus 2019 (COVID-19) has been controversial. We performed a meta-analysis of all published studies that reported the outcomes of ACEIs/ARBs in patients with COVID-19. We included four observational studies (3,267 patients). The use of ACEIs/ARBs was associated with a similar risk of all-cause death (OR: 0.75, 95% CI [0.36, 1.57], p = 0.45). Sensitivity analysis including only hypertensive patients demonstrated a lower risk of death with ACEIs/ARBs use (OR: 0.57, 95% CI [0.32-0.98], p = 0.04). In conclusion, hypertensive patients with COVID-19 treated with ACEIs/ARBS have a lower mortality but further research is needed.

Abstract Importance:SARS-CoV-2 virus gains access and infects target cells via angiotensin converting enzyme 2 (ACE2) receptor. Because angiotensin converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) could increase the expression of ACE2, there are growing concerns that their use could increase the risk of SARS-CoV-2 infection. Cardiac societies have called for epidemiological research about this emerging controversy. Objective:We sought to systematically review the literature and perform a meta-analysis about prior use of ACEI/ARBs and risk of SARS-CoV-2 infection.Data source:We searched multiple data sources including PubMed , ClinicalTrial.org , and medrxiv.org from November 2019 through May 16, 2020. Study selection:Any study that reported on the adjusted association of prior use of ACEIs / ARBs and risk of acquiring SARS-CoV-2 infection was eligible. Two authors independently reviewed eligible studies and extracted data into a prespecified data collection form. Data synthesis:An inverse variance meta-analytic approach was used to pool adjusted odds ratios using a random effect model meta-analysis. I2 test was used to assess in-between studies heterogeneity. The Newcastle–Ottawa quality assessment scale (NOS) was used to assess the quality of included studies. Main outcome and Measures:The association between the prior use of ACEIs or ARBs and risk of SARS-CoV-2 infection was assessed using pooled OR and 95% confidence interval. Results:Six case control studies that enrolled a total of 5657 patients (2536 patients in ACEIs arm and 3121 patients in ARBs arm ) and 721,859 controls were included in our meta-analysis. Two of the included studies were from the USA, one from Italy, one from China, one from Spain, and one from South Korea. All included studies scored high based on NOS scale. Prior use of ACEIs was not significantly associated with an increased risk of SARS-CoV-2 infection, OR 0.93, CI (0.85,1.02), I2=20%. Similarly, prior use of ARBs was not significantly associated with an increased risk of SARS-CoV-2 infection, OR 0.86, CI (0.67,1.10), I2=93%. Sensitivity analysis was performed by removing a study that could have been affected by residual confounding; OR for ARB 1.04, CI (0.96,1.12), I2=32%.Conclusion:Findings from this systematic review and meta-analysis suggest that prior use of ACEIs or ARBs is not associated with a higher risk of COVID-19. Our results are in support of the recent recommendations of cardiac societies and provide a reassurance to the public not to discontinue prescribed ACEIs/ARBs due to fear of COVID-19.
