| Popis: | Objective. To search for predictors of mortality for patients in need of intra-aortic balloon pump (IABP) support in the course of car- diac surgery. Methods. A retrospective study of possible pre- and perioperative risk factors in 110 patients with mean age of 62 years (38-79). The IABP was inserted preoperatively in 19 (17%) and perioperatively in 91 (83%). Results'. Well known risk factors as advanced age (63.2/61.0; P=0.25), NYHA functional class (OR= 1.59; 95% CI 0.23 to 13.31), female sex (OR=2.40; 95% CI 0.81 to 6.73), emergency surgery (OR = 0.63; 95 % CI 0.21 to 1.80), low left ventricular ejection fraction (62.9/60.7; P = 0.53), or elevated end diastolic pressure (19.4/2t.0; P=0.48), were not prognostic of death. Periopera- tive insertion of the balloon pump (OR=3.83; 95% CI 1.07 to 14.95), perioperative myocardial infarction (OR=23.3; 95% CI 7.62 to 81.8), low cardiac output (OR=7.53; 95% CI 2.43 to 24.11), and renal failure (OR=20.00; 95% CI 3.63 to 145), were strong predictors of death. Conclusions. Outcome seemed to be determined by perioperative events rather than preoperative risk factors. This could possibly explain the fa- vourable mortality rates seen in pa- tients on IABP support prior to sur- gery compared to patients who had IABP installed perioperatively.
