We performed a systematic review and meta-analysis to investigate the diagnostic performance of three methods of TTE (non-contrast, contrast, and apical wall motion scoring) for the detection of LVT compared to CMR as a reference test. Studies comprising 2113 patients investigated for LVT using both TTE and CMR were included in the meta-analysis.

The aim of this study was to assess the correlation between EAT and left ventricular (LV) function, and to determine the prognostic value of EAT in patients with SSc. Methods and results Consecutive patients with SSc who underwent non-contrast thorax computed tomography and echocardiography were included. EAT mass was quantified using dedicated software. The study endpoint was all-cause mortality. A total of 230 SSc patients [age 53±15 years, 14% male] were included. The median value of EAT mass was 67g (IQR: 45-101g). Patients with increased EAT mass (≥67g) showed more impaired LV diastolic function as compared to patients with less EAT mass (&amp;lt;67g), and even after adjusting for age and comorbidities, EAT mass was independently associated with LV diastolic function parameters. During a median follow-up of 8 years, 42 deaths occurred. Kaplan-Meier analysis showed that patients with increased EAT mass had higher all-cause mortality rate as compared to patients with less EAT mass (29% vs 7 %; P&amp;lt;0.001). In the multivariable analysis, EAT was independently associated with all-cause mortality after adjusting for important covariates (HR:1.006; 95%CI:1.001-1.010).
