PCA subtypes linked to divergent post-bypass survival; hypothesis-generating and requires prospective validation before clinical use.
Does principal-component analysis of angiographic, histologic, and electrocardiographic data identify prognostic subtypes in patients undergoing aortocoronary bypass grafting?
Identification of subtypes of coronary artery disease using angiographic, histologic, and ECG data can help estimate patient prognosis after coronary surgery.
Flameng et al. (1984) studied this question.
