Presystolic wave (PSW) is a late diastolic wave encountered in the left ventricular outflow tract (LVOT) and is associated with increased left ventricular stiffness and decreased left ventricular compliance. In our study, MPI was compared between patients with metabolic syndrome and normal patients, and we also investigated whether PSW could predict subclinical left ventricular dysfunction (SCLVD) in patients with metabolic syndrome. A total of 119 patients, 59 with metabolic syndrome and 60 healthy volunteers, were included in our study. Our study is a two-center prospective study. The patient groups were compared in terms of demographic, laboratory and echocardiographic parameters. Univariate and multivariate regression analyzes were performed to detect predictors of SCLVD. Higher MPI and PSW were found in patients with metabolic syndrome compared to the normal population (0.56 ± 0.11 vs. 0.46 ± 0.07, p < 0.001, 34 (57.6%) vs. 19 (31.7%), p = 0.004, respectively).

However, there is still a lack of evidence of correct patient selection for percutaneous coronary intervention (PCI). From July 2017 to August 2020, 68 patients with successful PCI of a CTO and previous evidence of viability for PCI by cardiovascular magnetic resonance imaging (CMR) were prospectively included in this single-centre observational study. Of these patients, 62 underwent follow-up CMR, and 56 underwent surveys using the Seattle Angina Questionnaire before PCI and 3, 12 and 24 months after PCI. The CMR results were assessed for volumetric, functional and deformation parameters. From the baseline to the follow-up, there was a significant reduction in the left ventricular volumes (all p < 0.001) and an increase in the left ventricular ejection fraction (57.6 ± 11.6% vs. 60.3 ± 9.4%, p = 0.006). Among the deformation parameters, only the left ventricular radial strain showed significant improvement. The SAQ showed an early improvement that emphasised angina stability and frequency as well as a summary score, which persisted after 24 months. A low SAQ summary score before PCI was the best predictive factor of good clinical improvement thereafter. Improvements in myocardial function and quality of life can be achieved with PCI of a CTO. Patient selection for PCI should be performed primarily among relevantly symptomatic patients when evidence of viability for PCI is present. The SAQ can help guide such patient selection.Trial registration ISRCTN, identifier: ISRCTN33203221.

A DNN was trained to discriminate PLN variant carriers (n = 278) from control subjects (n = 621) using raw deformation curves obtained by 2D-speckle tracking in the longitudinal axis. A visualization technique was used to identify the parts of these curves that were used by the DNN for classification. The PLN variant carriers were clustered according to the output of the visualization technique. The DNN showed excellent discriminatory performance (C-statistic 0.93 [95% CI 0.87-0.97]). We identified four clusters with PLN-associated disease features in the deformation curves. Two clusters showed previously described features: apical post-systolic shortening and reduced systolic strain. The two other clusters revealed novel features, both reflecting delayed relaxation. Additionally, a fifth cluster was identified containing variant carriers without disease features in the deformation curves, who were classified as controls by the DNN. This latter cluster had a very benign disease course regarding development of ventricular arrhythmias.
