Preoperative Intraaortic Balloon Pump Enhances Cardiac Performance and Improves the Outcome of Redo CABG

摘要: Background Reoperative coronary artery bypass grafting (redo CABG) is associated with an increased operative risk compared primary CABG. Because the hospital mortality in redo CABG known to be influenced by poor left ventricular function (left ejection fraction ≤0.40), unstable angina, and main stem stenosis greater than or equal 70%, a preoperative intraaortic balloon pump (IABP) support could beneficial improve outcome high-risk Methods Between June 1994 October 1996, 48 patients underwent were randomized into following groups: group 1 (24 patients) who received IABP treatment on average 2hours before cardiopulmonary bypass, 2 no served as controls. Mean age was 65 years 90% (43 men. Forty-one had less 0.40 (85%), 38% (18 54% (26 angina preoperatively. Preoperative patient characteristics did not differ between groups. Results The time shorter 1, 86 versus 110 minutes ( p =0.006). There deaths but four occurred control =0.049). Cardiac index rose significantly preoperatively after introduction of 1. higher postoperatively remained during first 24hours bypass. Significantly fewer postoperative low cardiac output (4 13 patients). Nine required for 4.1±1.7 days. Only needed postoperatively, their IABPs successfully removed day. IABP-supported intensive care unit stay, 2.4±0.8 days 2, 4.5±2.2 =0.007), well stay. found cost-effective. Conclusions effective modality prepare these have myocardial revascularization nonischemic situation possible, which resulted lower mortality, instances output, stays both hospital.
