Aims The aim of this review to assess cardiac involvement in patients with severe COVID-19 patients. We review all patients with COVID 19 disease admitted in our trust requiring transthoracic echocardiograms on their clinical indications. Background Cardiac involvement in COVID-19 disease has been found to be prognostic factor and has been related with higher mortality and morbidity. In a large series with COVID-19 those with heart disease had a fatality rate around 10.5%.1 2 Methods All adult patients who were COVID-19 positive on PCR admitted between March 2020 and February 2021, who had an echocardiogram, were identified through our local database. Their demographics, co-morbid, troponin levels and Pro NT-BNP were analysed. All echocardiograms reports which were finalised by the imaging cardiologist were included in our analysis. Results There were a total of 41 patients who had echocardiograms during their stay in the hospital with COVID-19 disease. Mean age was 70 (range 45-90) years old. There were 70% male and 30% female patients. 12% were diabetic, 49% hypertensive and 40% had previous heart disease. Pulmonary embolism diagnosed in 10% of patients by CT pulmonary angiogram. 56% of patients required high flow oxygen and 21% need mechanical ventilation. Almost all patients had troponin and CRP levels on admission. Mean troponin level 215 and mean CRP levels were 197. Mean D dimer levels 1130, and mean creatinine levels were 138. 92% had evidence of lung involvement in chest X-ray. 13% patients had new evidence of a diagnosis of left ventricular dysfunction on echocardiography. Similarly, 27% had a new diagnosis of right ventricular dysfunction. Mean left ventricular diastolic dimension were 4.6 cm and systolic dimension. 2% had echo diagnosis of left ventricular thrombus echocardiographic studies. Mean PA pressure on echocardiography were 35 mmHg and mean E/A ratio was 1.2. 17% of patients were found to have pericardial effusion but none causing haemodynamic compromise. Conclusion This data suggests high incidence of right and left ventricular involvement in patients with severe COVID-19 disease. We recommend that all patients with COVID-19 disease admitted to hospital and requiring oxygen should have transthoracic echocardiograms during their admission.
