Effects of hypertension on the outcomes of COVID-19: a multicentre retrospective cohort study

Abstract

Objectives: Hypertension is thought to be a contributor to mortality in coronavirus disease 2019 patients; however, limited clinical data on the outcomes of COVID-19 in patients with hypertension are available. Methods: This study was designed to confirm whether hypertension affects the outcomes of COVID-19. Results: A total of 983 patients with COVID-19 (female, 48%; male, 52%) were enrolled.
