Abstract

Coronary Artery Disease (CAD) is the mostleading Cardiovascular Disease (CVD), which results due to buildup of plaque inside the coronary arteries. The CAD and Normal Sinus Rhythm (NSR) heartbeats can be discriminated and diagnosed noninvasively using the standard tool Electrocardiogram (ECG). However,manual diagnosis of ECG is tiresome and timeconsuming task, due to complex nature and unseennonlinearities of ECG. Hence an automated system playsa substantial role. In this study, CAD and NSRheartbeats are discriminated and diagnosed using Higher-Order Statistics (HOS) cumulants features. Further, the cumulants coefficients dimensionality reduced using Principal Components Analysis (PCA) and the medically significant features (p-value<0.05) Principal Components (PCs) are subjected forclassification using Random Forest (RAF) and RotationForest (ROF) ensemble classifiers. Proposed system isrobust which helps in screening CAD risk factors andtelemonitoring applications.
