Abstract
BACKGROUND

Patients with coronavirus disease 2019 (COVID-19) infection frequently have hypertension as a co-morbidity, which is linked to adverse outcomes. Antihypertensives may affect the outcome of COVID-19 infection.

AIM

To assess the effects of antihypertensive agents on the outcomes of COVID-19 infection.

METHODS

A total of 260 patients were included, and their demographic data and clinical profile were documented. The patients were categorized into nonhypertensive, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB), calcium channel blocker (CCB), a combination of ACEI/ARB and CCB, and beta-blocker groups. Biochemical, hematological, and inflammatory markers were measured. The severity of infection, intensive care unit (ICU) intervention, and outcome were recorded.

RESULTS

The mean age of patients was approximately 60-years-old in all groups, except the nonhypertensive group. Men were predominant in all groups. Fever was the most common presenting symptom. Acute respiratory distress syndrome was the most common complication, and was mostly found in the CCB group. Critical cases, ICU intervention, and mortality were also higher in the CCB group. Multivariable logistic regression analysis revealed that age, duration of antihypertensive therapy, erythrocyte sedimentation rate, high-sensitivity C-reactive protein, and interleukin 6 were significantly associated with mortality. The duration of antihypertensive therapy exhibited a sensitivity of 70.8% and specificity of 55.7%, with a cut-off value of 4.5 years and an area under the curve of 0.670 (0.574-0.767; 95% confidence interval) for COVID-19 outcome.

CONCLUSION

The type of antihypertensive medication has no impact on the clinical sequence or mortality of patients with COVID-19 infection. However, the duration of antihypertensive therapy is associated with poor outcomes.

Core Tip: Hypertension is a common co-morbidity among patients with coronavirus disease 2019 (COVID-19) infection. Antihypertensives have various effects on the outcome of COVID-19. In this single-center study, we evaluated the effects of antihypertensives, especially angiotensin-converting enzyme inhibitors, beta-blockers, and calcium channel blockers, on the outcome of COVID-19 infection. Duration of antihypertensive therapy rather than the type of antihypertensive medication was significantly associated with poor outcomes.
