ARTICLE HIGHLIGHTS
Research background

During the coronavirus disease 2019 (COVID-19) pandemic, several studies have revealed that sustained ingestion of angiotensin converting enzymes inhibitors or angiotensin receptor blockers (ACEIs/ARBs) had no harmful effects on COVID-19 patients complicated with hypertension.

Research motivation

The role of angiotensin converting enzyme-2 (ACE2) receptor in COVID-19 pathophysiological process remains unclear. We expect to provide more important evidence for ACEIs/ARBs usage in clinical application.

Research objectives

To explore the impact of ACEIs/ARBs discontinued usage on COVID-19 patients complicated with hypertension.

Research methods

This study was based on a COVID-19 cohort from a patient registry of all COVID-19 patients admitted to an isolated unit in a tertiary hospital. All COVID-19 patients complicated with hypertension were recruited in our study and divided into discontinued ACEIs/ARBs group or other anti-hypertensive drugs group. We compared characteristics and clinical outcomes between those two different groups of patients.

Research results

A total of 53 patients were enrolled, 27 patients switched from ACEIs/ARBs to CCBs while 26 patients continued with non-ACEIs/ARBs. After controlling potential confounding factors using the Cox proportional hazards model, hospital stay was longer in patients who discontinued ACEIs/ARBs, with a hazard ratio (HR) of 0.424 [95% confidence interval (CI): 0.187-0.962; P = 0.040], than in patients using other anti-hypertensive drugs. A sub-group analysis showed that the effect of discontinuing ACEIs/ARBs was stronger in moderate cases [HR = 0.224 (95%CI: 0.005-0.998; P = 0.0497)].

Research conclusions

Our data revealed that discontinuing ACEIs/ARBs treatment after COVID-19 diagnosis results in a prolonged hospital stay. This phenomenon was more significant in hospitalized patients with moderate COVID-19. Our research suggested that ACEIs/ARBs should be continued in patients with both COVID-19 and hypertension unless further evidence demonstrates adverse outcomes.

Research perspectives

The mechanism of ACE2 in COVID-19 patients complicated with hypertension remains unclear and may be more complex, requiring further research to explore this area in the future.
