Abstract		Introducing a new mechanical cardiac support into a surgical practice assumes, among other things, the risk stratification. However the favourable outcome would not relate barely to the performance of device, but would rather concem all other risk factors that could be identified in clinical data sets. A pilot study on the 24 patients undergoing coronary artery bypass surgery (CABG) addressed the performance and features specific of the Hemopump (HP). A comparative analysis of 36 patients was done to compare the new device (HP) to commonly used Intra-Aortic Balloon Pump (IABP). Results of multivariate discriminant analysis showed that the choice of the assist device did not affect survival. Operative mortality related to a greater number of the bypass grafts, increased age, and the Higgins score, which is a risk factor extracted from the large clinical data sets of several thousand patients in North America. Regression analysis predicted that an early surgical intervention is favourable of the positive patient outcome. Risk factors identified by the study could be seen as a part of a wider theoretical framework, and could be forwarded into the clinical practice using electronic patient record system.
