Association of coronary anatomical complexity with clinical outcomes after percutaneous or surgical revascularization in the Veterans Affairs clinical assessment reporting and tracking program
JAMA Jul 03, 2019
Valle JA, et al. - Through a cross-sectional observational multiple-center study of 50,226 patients who underwent percutaneous or surgical revascularization, experts assessed if an anatomical scoring system for use with registry data, allowed facile and automatic calculation of scores and correlations with clinical outcomes among such patients. Out of 50,226 patients who underwent percutaneous or surgical revascularization, 34,322 underwent percutaneous coronary intervention and 15,904 underwent coronary artery bypass grafting. The greatest tertile of anatomical complexity was related to an elevated hazard of major adverse cardiovascular and cerebrovascular events. Only repeat revascularization was correlated with growing complexity in this subgroup, post-adjustment. To determine the longitudinal risk for patients undergoing revascularization, an automatically computed score assessing anatomical complexity could be utilized. Furthermore, for learning longitudinal risk across large data sets, this simplified scoring system seemed to be an alternative tool.
