Abstract

Abstract: Background: Myocardial strain assessed with speckle tracking echocardiography is a sensitive marker of cardiac dysfunction. Both left‐ventricular global longitudinal strain (LV‐GLS) and right ventricular longitudinal strain (RV‐LS) were affected by severe SARS‐CoV‐2 infection. However, data about cardiac involvement in patients with asymptomatic/mild Coronavirus disease‐19 (COVID‐19) is still lacking. Aim: To evaluate myocardial function using LV‐GLS and RV‐LS in patients with previous asymptomatic/mild COVID‐19. Methods: Forty young adults without previously known comorbidities/cardiovascular risk factors and with a confirmed diagnosis of asymptomatic or paucisymptomatic SARS‐CoV‐2 infection were retrospectively included. A 2D‐transthoracic echocardiogram with speckle tracking analysis was performed at least 3 months after the diagnosis. Forty healthy subjects, matched for age, sex, and body surface area in a 1:1 ratio were used as the control group. Results: Left ventricular ejection fraction (LVEF), tricuspid annular plane systolic excursion (TAPSE) and RV‐LS were comparable between the two groups. LV‐GLS was significantly lower in the cases compared to the control group (−22.7 ± 1.6% vs. −25.7 ± 2.3%; p < .001). Moreover, the prevalence of regional peak systolic strain below −16% in at least two segments was three times higher in patients with previous COVID‐19 compared to controls (30% vs. 10%, p = .02). In multivariable logistic regression, previous COVID‐19 infection was independently associated with reduced LV‐GLS values ( p < .001). Conclusion: SARS‐CoV‐2 infection may affect left ventricular deformation in 30% of young adult patients despite an asymptomatic or only mildly symptomatic acute illness. Speckle‐tracking echocardiography could help early identification of patients with subclinical cardiac involvement, with potential repercussions on risk stratification and management.
