Clinical features of arterial hypertension in patients with mild and moderate COVID-19

Abstract

Objective: to clarify the clinical and diagnostic features of arterial hypertension in patients with mild and moderate forms of COVID-19, taking into account the elapsed time. Material and methods. We examined 116 patients aged 44-60 years who were admitted to the hospital with uncontrolled stage 2 arterial hypertension, 96 of them had mild and moderate COVID-19. The patients were divided into two groups: the first group up to 12 weeks after suffering COVID-19 and the second group after 12 weeks. The examination included echocardiography and ambulatory blood pressure (BP) monitoring. Results. In post-COVID-19 patients, the ratio of daytime to nighttime systolic BP was statistically significantly lower than in disease-free patients (p <0,001, p1 =0,015). There was a decrease in the daily BP index in the group 1 and group 2 (11.6±0.8% and 12.2±1.2%, respectively, p=0,001). Among patients after COVID-19, non-dippers were detected, more often in group 1 (9 people (17.6%) versus 2 people (4.4%) (x2=4.18, p=0.042). Conclusion. Arterial hypertension in patients who underwent mild and moderate COVID-19 was characterized by an insufficient decrease in systolic blood pressure at night, the presence of non-dippers with positive dynamics after 12 weeks from the onset of the infectious process.
