Effect of hypertension on outcomes of patients with COVID-19

To determine the impact of hypertension on the outcomes of patients with COVID-19. This matched cohort study was conducted among a total 442 patients with COVID-19 admitted in Honghu People's Hospital and First Affiliated Hospital of Nanchang University between January 1 to March 18, 2020, including 61 patients with hypertension and 381 normotensive patients. To minimize the effects of the confounding factors including age, gender and other comorbidities, we excluded patients with comorbidities other than hypertension, and matched the patients with and without hypertension for age and gender at a 1:1 ratio. We analyzed the clinical characteristics, laboratory findings and clinical outcomes of in 32 matched pairs of patients with and without hypertension. Compared with the normotensive patients, COVID-19 patients with hypertension were more likely to develop bacterial infections ( =0.002) and had higher neutrophil counts ( =0.007), neutrophil/lymphocyte ratio ( =0.045), and lactate dehydrogenase levels ( =0.03
