Abstract
BACKGROUND: About 10% to 15% of patients undergoing cardiac surgery may develop low cardiac output syndrome in the perioperative period; of this total, 2% require mechanical support for adequate hemodynamic control. OBJECTIVE: To describe the mortality rates of patients who required the use of IABP in the perioperative or postoperative period of cardiac surgery, identifying preoperative variables associated with a worse outcome, as well as to describe the postoperative complications and medium-term survival. METHODS: Retrospective cohort study including 80 consecutive cases between January/2009 and September/ 2011. The patients had on average 62.9 ± 11.3 years and 58.8% were male; 81.3% were hypertensive, 50.0% had prior myocardial infarction and 38.8% has NYHA III/IV heart failure. The mainsurgery performed was isolated coronary artery bypass grafting (37.5%). RESULTS: Hospital mortality was 53.8% (IC 95%: 42.7-64.9), and cross-clamp time > 90 minutes was an independent predictor of mortality in multivariate analysis (OR 1.52 CI 95%: 1.04-2.22). 71.3% of patients (CI 95%: 61.2-81.4) had at least one additional complication in the perioperative period, with lower limb ischemia observed in 5.0% patients. One-year survival was 43.6%, with a plateau in survival rates after a sharp initial drop, related to hospital mortality. CONCLUSION: Patients who require IABP comprise a group of very high risk for morbidity and mortality. IABP use, however, enables the recovery of many patients from an evolution that would invariably be fatal, and patients discharged from hospital have a good medium-term survival.
