the prognostic value of echocardiographic findings in prediction of in-hospital mortality of covid-19 patients

Introduction: the correlation between echocardiographic findings and the outcome of covid-19 patients is still under debate. objective: in the present study it has been endeavored to evaluate the cardiovascular condition of covid-19 patients using echocardiography and to assess the association of these findings with in-hospital mortality. methods: in this retrospective cohort study, hospitalized covid-19 patients from february to july 2020 with at least one echocardiogram were included. data were extracted from patients’ medical records and the association between echocardiographic findings and in-hospital mortality was assessed using a multivariate model. the findings were reported as relative risk (rr) and 95% confidence interval (95% ci). results: data from 102 covid-19 hospitalized patients were encompassed in the present study (63.7±15.7 mean age; 60.8% male). thirty patients (29.4%) died during hospitalization. tricuspid regurgitation (89.2%), mitral valve regurgitation (89.2%), left ventricular (lv) diastolic dysfunction (67.6%), pulmonary valve insufficiency (pi) (45.1%) and lv systolic dysfunction (41.2%) were the most common findings on patients’ echocardiogram. the analyses of data showed that lv systolic (p=0.242) and diastolic (p=0.085) dysfunction was not associated with in-hospital mortality of covid-19 patients, while the presence of pi (rr=1.85; 95% ci: 1.02 to 3.33; p=0.042) and patients’ age (rr=1.03; 95% ci: 1.01 to 1.08; p=0.009) were the two independent prognostic factors of in-hospital mortality.conclusions: it seems that lv systolic and diastolic dysfunction was not associated with in-hospital mortality of covid-19 patients. however, presence and pi and old age are possible prognostic factors of covid-19 inhospital mortality. therefore, using echocardiography might be useful in management of covid-19.
