ABSTRACT
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 and Methods: In this retrospective cohort study, 235 patients requiring IABP 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 [CPB] 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 CPB [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
