Mortality and morbidity from intra-aortic balloon pumps. Risk analysis

Area of Science:

• Cardiology
• Vascular Surgery
• Critical Care Medicine

Background:

• Postoperative intra-aortic balloon pump (IABP) support is utilized in high-risk cardiac surgery patients.
• Assessing the incidence and predictors of mortality and morbidity following IABP use is crucial for patient outcomes.

Purpose of the Study:

• To evaluate the incidence of mortality and morbidity in patients requiring postoperative intra-aortic balloon pump (IABP) support.
• To identify independent predictors of mortality, vascular complications, and renal insufficiency after IABP insertion.

Main Methods:

• Retrospective analysis of 116 patients who received postoperative IABP support.
• Statistical analysis including multivariate analysis to identify significant predictors.

Main Results:

• Mortality rate was 57.8%. Major vascular complications occurred in 16.3% (limb ischemia, aortic dissection, mesenteric infarction).
• Minor vascular complications (bleeding, infection) occurred in 25.8%. Renal insufficiency affected 51.7%, with 40% requiring dialysis.
• Neurological complications (10.3%), thrombocytopenia (11.2%), and sepsis (4.3%) were also observed.

Conclusions:

• IABP insertion incidence was 1.5% in this institution, with a mortality rate comparable to other studies.
• Independent predictors of mortality include IABP timing, thrombocytopenia, peripheral vascular disease, and redo intervention.
• Predictors for limb ischemia include female sex, diabetes, smoking, and antiplatelet use. Low ejection fraction and no dobutamine predict renal insufficiency.
