Diastolic dysfunction increases the risk of acute kidney injury (AKI) in patients with severe COVID-19. Using point-of-care ultrasound (PoCUS) to assess left ventricular diastolic function in the ICU may be a useful parameter to stratify AKI risk.

A single-centre, retrospective, case-control study of severe COVID-19 patients aged 18 years or older between March 2020 and January 2022.

Patients with end-stage renal disease (ESRD) or on dialysis were excluded.

Each COVID-19 patient enrolled in the study underwent a cardiac ultrasound within 48 hours of admission.

82 patients were included in the present study, with a mean age of 62.6 ± 12.2 years, a predominantly male population (75.6%), and hypertension (61.0%) as the main comorbidity.
