Myocardial Injury

Hybrid Feature Selection in a Machine Learning Predictive Model for Perioperative Myocardial Injury in Noncoronary Cardiac Surgery with Cardiopulmonary Bypass

This study developed a predictive model for perioperative myocardial injury (PMI) using hybrid feature selection (FS) methods in patients undergoing noncoronary cardiac surgery with cardiopulmonary bypass (CPB). Conducted at Fuwai Hospital, China, the retrospective study included 1130 patients, with an overall PMI incidence of 20.3%. Various machine learning models were evaluated, with the Naïve Bayes model achieving the highest AUC. The study highlighted the importance of factors like prolonged CPB, aortic clamp time, and preoperative low platelet count in predicting PMI risk.

A Systematic Review of Cardiac Surgery Clinical Prediction Models That Include Intra-operative Variables

This systematic review assesses clinical prediction models (CPMs) that incorporate intra-operative variables to predict outcomes following adult cardiac surgery. It highlights the identification of 24 CPMs, predominantly predicting acute kidney injury and peri-operative mortality, using common variables like cardiopulmonary bypass time. Despite acceptable discrimination in internally validated models, poor calibration and high bias risk limit their practical use. The review suggests potential improvement in model accuracy with intra-operative data, advocating for more robust studies.

Utilizing Machine Learning to Predict Neurological Injury in Venovenous Extracorporeal Membrane Oxygenation Patients: An Extracorporeal Life Support Organization Registry Analysis

In a study analyzing 37,473 VV-ECMO patients, machine learning was used to predict acute brain injury (ABI), revealing a 7.1% incidence of ABI and identifying pre-ECMO cardiac arrest as the most significant risk factor. The study’s machine learning models, however, showed sub-optimal performance in predicting ABI, attributed to the low prevalence of ABI and the lack of standardized neuromonitoring and imaging protocols in the ELSO Registry data.
