Background: The Severe acute respiratory syndrome coronavirus 2, is the pathogen that causes COVID-19. Cardiovascular (CV) involvement during this infection, has been related to adverse outcomes. Interestingly, some patients may remain symptomatic beyond the first 14 days of disease diagnosis. Although a particular reduction on left ventricular (LV) global longitudinal strain (GLS) in basal segments has been recently described in patients hospitalized with diagnosis of COVID-19, the correlation of these findings with the persistence of symptoms has not been determined. Objectives: The objective of this study is to describe echocardiographic findings in patients recovered from COVID-19 and to determine its association with persistent dyspnea. Methods: Seventy-six patients were analyzed. Forty-six were asymptomatic (group N°1) and 30 referred persistent dyspnea at the time of examination (group N°2), and a cohort of 25 healthy individuals was included as a control group. Total LV GLS, average basal LV GLS, and average mid-apical LV GLS were assessed. Basal-mid-apical index (BMAI) was calculated. A difference in BMAI bigger than 15% between both groups was stablished as cutoff point. Results: Nonsignificative differences on standard echocardiographic measurements were found between the analyzed groups. When compared to the control group, there was nonsignificative reduction on basal LV GLS values in patients with persistent dyspnea. However, BMAI values were bigger than 15% in 70% of patients from group N°2 but in none of the patients from the control group (P = 0.0002). Conclusions: This new index allowed to identify an abnormal relation in LV GLS values between basal and medium-apical segments among patients recovered from COVID-19 and persistent dyspnea.
