This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Background:
Cardiac involvement in coronavirus disease 2019 (COVID-19) is associated with poor outcomes. Transthoracic echocardiography (TTE) can be used to assess cardiac structure and function non-invasively, and has been shown to influence management in COVID-19.Objectives:
We aim to investigate the prognostic value of TTE findings in hospitalized adults with confirmed COVID-19.Methods:
All consecutive hospitalized adult patients with confirmed COVID-19 who underwent TTE assessment between 3rd April 2020-6th April 2021 were included. Comprehensive clinical data including TTE findings were collected from electronic medical records. Patients with mild-moderate and severe-critical COVID-19 were compared. Within the severe-critical group, patients who survived hospitalization and died were compared. Further analyses were conducted after matching for age >60 years, obesity, and diabetes.Results:
A total of 488 COVID-19 patients were included in this study; 202 with mild-moderate and 286 severe-critical disease. All mild-moderate patients and 152 severe-critical patients survived hospitalization. In the matched cohorts, TTE findings associated with severe-critical COVID-19 included left ventricular (LV) hypertrophy (OR 1.91; CI 1.21-3.02), LV diastolic dysfunction (OR 1.55; CI 1.00-2.38), right ventricular (RV) dysfunction (OR 3.86; CI 1.06-14.08), wall motion abnormalities (WMAs) (OR 2.76; CI 1.28-5.96), and any TTE abnormalities (OR 2.99; CI 1.73-5.17). TTE findings associated with mortality included RV dysfunction (OR 3.53; CI 1.12-11.19) and WMAs (OR 2.63; CI 1.26-5.49).Conclusion:
TTE is a non-invasive modality that can potentially be used for risk-stratification of hospitalized COVID-19 patients. These findings must be confirmed in larger prospective studies.
