Early intra-aortic balloon pumping following perioperative myocardial injury improves hospital and mid-term prognosis

We evaluated the impact of immediate intra-aortic balloon pumping (IABP) on hospital and mid-term outcome of coronary artery bypass graft (CABG) whenever perioperative acute complications developed. We compared clinical, biochemical, echocardiographic in-hospital results and two-year follow-up outcome of 30 low-risk (EuroSCORE<5) CABG (group A) who immediately received perioperative IABP when acute complications were suspected, to a contemporary, uncomplicated case-matched group (30 patients; Group B). Two in-hospital deaths were recorded in group A with no deaths in controls (P=0.492). Group A showed significantly higher lactate only at ICU arrival (P=0.001). Troponin I was always higher, but never reached values diagnostic for myocardial infarction (P<0.001). Worse left ventricular ejection fraction (P
