IPA and Coronary Artery Disease: A Case Study from Harvard
See how IPA was used for the discovery of novel pathways of affected genes in coronary artery disease. Cardiopulmonary bypass (CPB) with cardioplegic arrest is associated with ischemia leading to metabolic substrate depletion, reperfusion injury, apoptosis and necrosis. The study hypothesized that human left ventricular (LV) myocardium responds differently to the stress of (CPB) depending on the presence or absence of coronary artery disease (CAD). Therefore, they assessed differences in gene expression in patients undergoing aortic valve replacement (AVR) with (CPB) prior to and after cardioplegic arrest using whole-genome transcriptional profiling.
