(HealthDay News) — Transthoracic echocardiography (TTE) may identify hospitalized COVID-19 patients at higher risk for in-hospital death, according to a study published online in the European Journal of Clinical Investigation.

Angelo Silverio, MD, from the University of Salerno in Italy, and colleagues used data from 1401 patients hospitalized with COVID-19 from March 1 to April 22, 2020, in1 of 7 Italian centers to identify clinical conditions and echocardiographic parameters associated with in-hospital mortality.

The researchers found that 16.1% of patients underwent TTE, and of these patients, 30.1% died (68 of 226). There were independent associations for left ventricular ejection fraction (LVEF), tricuspid annular plane systolic excursion (TAPSE), and acute respiratory distress syndrome (ARDS) with in-hospital mortality. There was a significantly higher risk for mortality in patients with ARDS versus those without (hazard ratio, 7.66), in patients with TAPSE ≤17 mm versus those with TAPSE >17 mm (hazard ratio, 5.08), and in patients with LVEF ≤50% vs those with LVEF >50% (hazard ratio, 4.06).

“TTE might be a useful tool in risk stratification of patients with COVID-19,” the authors write.
