Insights
Antihypertensive medications like ACE inhibitors and ARBs were linked to lower COVID-19 diagnosis odds. Most antihypertensive therapies showed no increased risk for COVID-19 diagnosis or mortality.
Area of Science:
- Cardiology
- Infectious Diseases
- Pharmacology
Background:
- Antihypertensive drugs' role in COVID-19 susceptibility and severity is debated.
- Previous estimates may be affected by bias, particularly healthcare-seeking behavior.
- Understanding these associations is crucial for patient management during the pandemic.
Purpose of the Study:
- To investigate the association between specific antihypertensive medications and COVID-19 diagnosis.
- To evaluate the relationship between antihypertensive drug classes and COVID-19 related mortality.
- To account for potential confounding factors, including healthcare-seeking behavior.
Main Methods:
- A population-based case-control study using UK Clinical Practice Research Datalink data.
- Inclusion of 16,866 COVID-19 cases and 70,137 matched controls.
- Analysis of exposures including ACE inhibitors (ACEIs), ARBs, beta-blockers, calcium-channel blockers, thiazide diuretics, and other antihypertensives, adjusted for covariates and consultation frequency.
Main Results:
- ACE inhibitors and ARBs were associated with significantly lower odds of COVID-19 diagnosis.
- Calcium-channel blockers and thiazide diuretics also showed reduced odds of COVID-19 diagnosis.
- Beta-blockers showed an initial increased odds of diagnosis, which was attenuated after adjusting for consultation frequency. No antihypertensive class was associated with increased COVID-19 mortality.
Conclusions:
- Antihypertensive therapy, particularly ACE inhibitors and ARBs, is not associated with an increased risk of COVID-19 diagnosis or mortality.
- Most antihypertensive drug classes demonstrated a negative association with COVID-19 diagnosis.
- Findings suggest potential protective effects or that certain drug classes are prescribed to individuals with lower COVID-19 risk.
Aims:
Antihypertensive drugs have been implicated in coronavirus disease 2019 (COVID-19) susceptibility and severity, but estimated associations may be susceptible to bias. We aimed to evaluate antihypertensive medications and COVID-19 diagnosis and mortality, accounting for healthcare-seeking behaviour.
Methods:
A population-based case-control study was conducted including 16 866 COVID-19 cases and 70 137 matched controls from the UK Clinical Practice Research Datalink. We evaluated all-cause mortality among COVID-19 cases. Exposures were angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), beta-blockers (B), calcium-channel blockers (C), thiazide diuretics (D) and other antihypertensive drugs (O). Analyses were adjusted for covariates and consultation frequency.
Results:
ACEIs were associated with lower odds of COVID-19 diagnosis (adjusted odds ratio [AOR] 0.82, 95% confidence interval [CI] 0.77-0.88) as were ARBs (AOR 0.87, 95% CI 0.80-0.95) with little attenuation from adjustment for consultation frequency. C and D were also associated with lower odds of COVID-19 diagnosis. Increased odds of COVID-19 for B (AOR 1.19, 95% CI 1.12-1.26) were attenuated after adjustment for consultation frequency (AOR 1.01, 95% CI 0.95-1.08). Patients treated with ACEIs or ARBs had similar odds of mortality (AOR 1.00, 95% CI 0.83-1.20) to patients treated with classes B, C, D or O or patients receiving no antihypertensive therapy (AOR 0.99, 95% CI 0.83-1.18).
Conclusions:
There was no evidence that antihypertensive therapy is associated with increased risk of COVID-19 diagnosis or mortality; most classes of antihypertensive therapy showed negative associations with COVID-19 diagnosis.
