Why the study?
Persistent right ventricular involvement has been reported after COVID-19, but the association between persistent RV impairment and new-onset pulmonary hypertension remained unexplored.
What is the prevalence of pulmonary hypertension and right ventricular dysfunction in patients recovered from COVID-19?
What is the prevalence of pulmonary hypertension and right ventricular dysfunction in patients recovered from COVID-19?
Patients recovered from COVID-19 may have persistent right ventricular dysfunction (impaired longitudinal strain) even in the absence of pulmonary hypertension.
May support post-COVID RV monitoring; leaves open causal role of PH and need for prospective trials.
Right ventricular (RV) dysfunction (RVD) is associated with worse outcome in coronavirus disease 2019 (COVID-19). Pulmonary hypertension (PH) is a cause of RVD in COVID-19 respiratory failure and is associated with negative prognosis. Major pulmonary embolism, alveolar and endothelial injury, and thrombotic microangiopathy are potential triggers for new-onset PH in the acute phase. Persistent RV involvement has been reported in patients recovered from COVID-19. However, the association between persistent RV impairment and new-onset PH remains unexplored. We evaluated the prevalence of PH and RVD in patients recovered from COVID-19.
