Summary
Consensus among expert groups is to continue ACEi and ARB use when there is a specific indication for their use, even in patients diagnosed with COVID-19.
SARS-CoV-2 uses the angiotensin converting enzyme 2 (ACE2) receptor for entry into host target cells, the expression of which is increased by two common classes of antihypertensives: angiotensin-converting enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARB).1
Some have speculated that these medications may increase coronavirus disease 2019 (COVID-19) susceptibility or disease outcome.2
Retrospective studies3,4 and meta-analyses5 have thus far demonstrated that, among hypertensive patients hospitalized with COVID-19, mortality rate is not higher among those patients treated with ACEi/ARB. Thus, the safety of continuing ACEis and ARBs has been reinforced by several recent retrospective observational studies in COVID-19 patients.
Professional societies (American College of Cardiology, European Society of Cardiology, Hypertension Canada) have released statements regarding ACEi/ARB use during the pandemic; consensus among the groups is to continue their use, even in patients diagnosed with COVID-19, when there is a specific indication for their use (e.g., left ventricular [LV] dysfunction, chronic kidney disease [CKD], secondary stroke prevention).1,6 However, the new prescription of these agents over the other recommended first-line antihypertensive agents (i.e., thiazide diuretics [THZD] and calcium-channel blockers [CCBs]) must await the results of ongoing randomized controlled trials (RCTs).6
A table6 summarizing recommended initiation or continuation of ACEi/ARB in patients with COVID-19 and those at risk can be found here.
Note: This clinical question is an active area of research worldwide; conclusions and recommendations may change over time.
