Insights
Hypertension significantly increases the risk of severe or fatal coronavirus disease 2019 (COVID-19). This meta-analysis found a 2.5-fold higher risk, particularly in older individuals with COVID-19.
Area of Science:
- Cardiology
- Infectious Diseases
- Epidemiology
Background:
- Identifying clinical predictors for severe coronavirus disease 2019 (COVID-19) is crucial for risk stratification.
- Hypertension is a common comorbidity, but its association with COVID-19 severity requires further clarification.
Purpose of the Study:
- To evaluate the association between hypertension and severe or fatal outcomes in patients with COVID-19.
Main Methods:
- A meta-analysis was conducted using data from Scopus, Medline, and Web of Science.
- Studies reporting hypertension rates in severe/non-severe COVID-19 or survivor/non-survivor groups were included.
- Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated.
Main Results:
- Hypertension was associated with a 2.49-fold increased risk of severe COVID-19 (95% CI, 1.98-3.12).
- A 2.42-fold higher mortality risk was observed in hypertensive patients (95% CI, 1.51-3.90).
- Meta-regression indicated a correlation between older age and increased hypertension risk in severe COVID-19.
Conclusions:
- Hypertension is linked to a significantly higher risk of severe or fatal COVID-19.
- The increased risk associated with hypertension is more pronounced in older individuals.
- These findings support the importance of managing hypertension for better COVID-19 outcomes.
Introduction:
As the outbreak of coronavirus disease 2019 (COVID‑19) was recognized, the clinical predictors of severe or fatal course of the disease should be identified to enable risk stratification and to allocate limited resources optimally. Hypertension has been widely reported to be associated with increased disease severity; however, some studies reported different findings.
Objectives:
The study aimed to evaluate the association between hypertension and severe and fatal COVID‑19.
Patients And Methods:
The Scopus, Medline, and Web of Science databases were searched to identify studies reporting the rate of hypertensive patients in the population diagnosed with severe or nonsevere COVID‑19 or in COVID-19 survivors and nonsurvivors. The obtained data were pooled into a meta‑analysis to calculate odds ratios (ORs) with 95% CIs.
Results:
Hypertension was associated with a nearly 2.5‑fold increased risk of severe COVID‑19 (OR, 2.49; 95% CI, 1.98-3.12; I2 = 24%), as well as with a similarly significant higher mortality risk (OR, 2.42; 95% CI, 1.51-3.90; I2 = 0%). In a meta‑regression analysis, a correlation was observed between an increase in the mean age of patients with severe COVID‑19 and an increased log OR of hypertension and COVID-19 severity (P = 0.03).
Conclusions:
This pooled analysis of the current literature would suggest that hypertension may be associated with an up to 2.5‑fold higher risk of severe or fatal COVID‑19, especially in older individuals.
