In COVID-19 patients, LV diastolic and RV dysfunction are common, and acute RV dysfunction is frequently associated with clinical deterioration.
Answers are grounded in this paper and cite their sources.
Acute RV dysfunction may signal deterioration in COVID-19; hypothesis-generating and requires prospective validation before guiding care.
In COVID-19 infection, LV systolic function is preserved in the majority of patients, but LV diastolic function and RV function are impaired. Elevated troponin and poorer clinical grade are associated with worse RV function. In patients presenting with clinical deterioration at follow-up, acute RV dysfunction, with or without deep vein thrombosis, is more common, but acute LV systolic dysfunction was noted in ≈20%.
