BACKGROUND: The association of coronavirus disease 2019 (COVID-19) with hypertension has been one of the frequently discussed topics in current studies since hypertension was identified as a risk factor for coronavirus disease. However, no studies seem to be focused on the BP (blood pressure) in patients with hypertension after COVID-19. REPORT: This report presents the cases of five frail geriatric patients (avg. age 78.3 (+/-6.4) years) with sarcopenia and controlled hypertension (office BP < 140 mmHg) who were diagnosed with SARS-CoV-2. FINDINGS: Control ABPM performed after COVID-19 showed that these hypertensive patients were hypotensive and that the previously well-established therapy was suddenly too intensive for them. CONCLUSIONS: These findings suggest that BP control after COVID-19 is needed and that ABPM is, particularly in frail geriatric patients, by no means a luxury but a necessity.
