The Evaluation of Survival in Patients Who Need Intra aortic Balloon Pump (IABP) after Cardiac Surgery

Introduction:in some cases, assist devices are required to ensure an adequate cardiac output after cardiac surgery. intra-aortic balloon pump (iabp) is the most commonly used cardiac assist device, which provides first-line support for patients with heart failure. the aim of this study was to determine factors affecting the mortality rate of patients receiving iabp.materials & methods: in this retrospective cohort study 235 patients requiring labp support were analyzed over 14 years period (between january 1999 and december 2013) from which 137 patients survived the 30 days follow-up. perioperative and demographic factors such as age, weight, underlying disease, ejection fraction, ventricular aneurysm and cardiopulmonary bypass and cross clamp time were recorded and analyzed.results: the overall operative mortality was reported to be 41.7%. male-to-female ratio was 131:104 and the mean age of the subjects was 57.58 ± 11.07 years. early mortality rate was higher among young subjects and those with prolonged cbp (162.71±35.25, p < 0.001) and acc (129.94±54.39, p < 0.001). in addition, mortality rate was higher among females (p=0.04). patients’ weight, comorbidity, preoperative ejection fraction, ventricular aneurysm and stenosis of the left main coronary did not affect the mortality rate (p > 0.05).conclusion: iabp is a simple, effective method for temporary cardiac support, especially for aged patients. in addition, lower duration of surgery is associated with better surgical outcomes.
