Cardiologists say heart function may be key to survival from Covid-19 Scots heart specialists say the function of the right hand side of the heart which pumps blood to the lungs may be key to surviving Covid-19. Cardiologists at the Golden Jubilee Hospital in Clydebank with specialist heart intensive care treatment experience are investigating how many patients develop problems with the right ventricle and how this impacts on the severity of the illness. Patients across 12 ICUs in Scotland who are ventilated are undergoing non-invasive ultrasound scans of the heart to explore and monitor how the condition develops and the impact on the heart.
