Identifying Ventricular Arrhythmias and their Predictors by Applying Machine Learning Methods to Electronic Health Records in Patients with Hypertrophic Cardiomyopathy (HCM-VAr-Risk Model)
Clinical risk stratification for sudden cardiac death (SCD) in hypertrophic cardiomyopathy (HC) employs rules derived from ACCF/AHA guidelines or the HCM Risk-SCD model (C-index ∼0.69), which utilize a few clinical variables. We assessed whether data-driven machine learning methods that consider a wider range of variables can effectively identify HC patients with ventricular arrhythmias (VAr) that lead to SCD. We scanned the electronic health records of 711 HC patients fo r sustained ventricular tachycardia or fibrillation (VT/VF).
