Antihypertensives and their relation to mortality by SARS-CoV-2 infection.

Abstract

The role of antihypertensives, especially Renin–Angiotensin–Aldosterone System inhibitors, is still debatable in COVID‐19‐related severity and outcome. Therefore, we search for a more global analysis of antihypertensive medication in relation to SAS‐CoV‐2 severity using prescription data worldwide. The association between the percentage use of different types of antihypertensive medications and mortality rates due to a SARS‐CoV‐2 infection during the first 3 weeks of the pandemic was analyzed using random effects linear regression models for 30 countries worldwide. Higher percentages of prescribed angiotensin receptor blockers (ARBs) (β, 95% confidence interval [CI]; −0.02 [−0.04 to −0.0012]; p = .042) and calcium channel blockers (CCBs) (β, 95% CI; −0.023 [−0.05 to −0.0028]; p = .0304) were associated with a lower first 3‐week SARS‐CoV‐2‐related death rate, whereas a higher percentage of prescribed angiotensin‐converting enzyme inhibitors (ACEis) (β, 95% CI; 0.03 [0.0061–0.05]; p = .0103) was associated with a higher first 3‐week death rate, even when adjusted for age and metformin use. There was no association between the amount of prescribed beta‐blockers (BBs) and diuretics (Diu) and the first 3‐week death rate. When analyzing the combination of drugs that is used by at least 50% of antihypertensive users, within the different countries, countries with the lowest first 3‐week death rates had at least an angiotensin receptor blocker as one of the most often prescribed antihypertensive medications (ARBs/CCBs: [β, 95% CI; −0.02 [−0.03 to −0.004]; p = .009], ARBs/BBs: [β, 95% CI; −0.03 [−0.05 to −0.006]; p = .01]). Finally, countries prescribing high‐potency ARBs had lower first 3‐week ARBs. In conclusion, ARBs and CCB seem to have a protective effect against death from SARS‐CoV‐2 infection.
