Abstract Introduction The first case of COVID-19 infection was described in Wuhan, China, in December 20191. Shortly after, cases of limited human-to-human transmission were reported in other countries, which made the WHO declare the outbreak a Public Health Emergency of International Concern (ESPII) on January 30, 20202. Recent studies suggest that treatment with angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARAB) during acute COVID-19 infection has no effect on mortality3, but it is no evidence regarding the medium-term clinical implication of previous treatment with ACEI/ARAB on the prognosis of patients with COVID-19 infection. Purpose The aim of this study is to evaluate the clinical implication of the use of ACEI/ARB in the acute moment and in medium-term follow-up in patients after COVID-19. Methods It is a single-centre, retrospective, analytical observational study of cohorts based on all consecutive patients diagnosed with COVID-19 who were admitted during the first wave (March 10th until May 31st), of the pandemic in our health area. Survival analysis of main outcomes (mortality, heart failure, and major acute cardiovascular events [a composite of cardiovascular mortality, myocardial infarction and stroke]) were adjusted by multivariate logistic regression. Results Of the total population studied, 447,979 inhabitants, 1,030 (0.23%) were diagnosed with COVID-19 infection, of which 196 (19%) were under treatment with ACEI/ARB at the time of diagnosis. The main results showed that ACEI/ARB treatment (combined and individually) had no effect on mortality (Hazard Ratio [HR]: 1.64, 95% Confidence Interval [CI] 0.98 2.76, p=0.062), heart failure (HR: 0.98, 95% CI 0.53 1.79, p=0.942), thrombotic events (HR: 1.02, 95% CI 0.22 4.83, p=0.98) and major acute cardiovascular events (HR: 0.88, 95% CI 0.48 1.60, p=0.665). Conclusions In conclusion, previous treatment with ACEI/ARB in patients with COVID-19 had no effect on the 6-month prognosis, defined as mortality, heart failure, or major acute cardiovascular events. Withdrawal of ACEI/ARB in patients testing positive for COVID-19 would not be justified, in line with current recommendations of scientific societies and government agencies.
