Abstract
Background To investigate the association between hypertension and clinical outcomes, including in-hospital mortality, intensive care unit (ICU) admission, and invasive ventilation in patients with coronavirus disease 2019 (COVID-19) pneumonia.Methods We implemented a systematic search of PubMed for articles that assessed clinical outcomes of hypertensive patients infected with SARS-CoV-2. The primary outcomes evaluated included: in-hospital mortality, ICU admission, and the use of invasive ventilation.Results A total of 18 studies were included, involving 13,293 patients and covering from January 25, 2020, to April 20, 2020. The relationship between hypertension and prognosis in COVID-19 patients was evaluated. Results showed that hypertension was a risk factor for in-hospital mortality in COVID-19 patients (RR: 2.20, 95% CI, 1.83–2.65, P < .001). Moreover, patients with hypertension were more likely to be admitted to ICU (RR: 1.86, 95% CI, 1.13–3.07, P = .001) and to use invasive ventilation (RR: 2.99, 95% CI, 1.73–5.17, P < .001).Conclusions Among COVID-19 patients, those combined with hypertension had a significantly higher risk of in-hospital deaths, admission to ICU, and need for invasive ventilation.
