Comparing innovative AI algorithms to assess echocardiographic videos for clinical modelling.
We conduct a comparative study that employs the use of multiple dynamic deep learning algorithms to develop predictive models with video-based echocardiographic images using sample size determination as a key variable to assess optimal performance metrics. ⋯ Because semi-supervised models use both labelled and unlabelled data sets, our findings are significant in showing that performance of certain predictive models using mixtures of unlabelled and labelled data is comparable to those using only labelled data with similar sample sizes, thus obviating the need for large sample sizes of labelled data.

Low socioeconomic status adversely affects outcomes after coronary artery bypass grafting.
Although socioeconomic status (SES) is believed to affect patient outcomes after coronary artery bypass grafting (CABG), readmission data are sparse. In a national cohort, we analyzed the influence of SES on readmission, resource utilization, and mortality after CABG. ⋯ Patients with low SES have greater adjusted odds of mortality and readmission after CABG than patients with high SES.
