Two-dimensional Speckle-Tracking and Four-dimensional Echocardiographic Evaluation of Cardiac Involvement in Post-COVID-19 patients: Comparison of Symptomatic and Asymptomatic Groups.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Context: Subclinical myocardial dysfunction may follow mild COVID-19, highlighting the importance of early detection. Aims: To evaluate cardiac involvement in recently recovered COVID-19 patients using two-dimensional speckle-tracking echocardiography (2D-STE) and four-dimensional-transthoracic echocardiography (4D-TTE), comparing symptomatic and asymptomatic groups. Settings and Design: This study involves a prospective observational cohort study at a tertiary cardiac center. Subjects and Methods: Ninety-four adults (mean age 37 ± 7.5 years) post-COVID-19 recovery underwent echocardiographic evaluation at 1 and 3 months. Assessments included left and right ventricular (RV) function, myocardial strain using 2D STE, and left ventricular volumes and ejection fraction using 4D TTE. Statistical Analysis: Paired and independent Results: Statistically significant improvement was observed over time. Left ventricular end-diastolic volume decreased from 89.3 ml to 84.7 ml, left ventricular end-systolic volume from 31.9 ml to 29.4 ml, left ventricular ejection fraction (LVEF) increased from 64.8% to 66.0%, and left ventricular-global longitudinal strain improved from -23.8% to -24.7% (all Conclusions: Mild or asymptomatic COVID-19 infections may cause temporary cardiac dysfunction. 2D-STE and 4D-TTE are sensitive tools for early detecting subclinical myocardial involvement and guiding follow-up care.
