Introduction: Insome 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.
