Abstract
Background: Intervention in high-risk patients with coronary artery disease has a low success rate and higher risk of complications. The intra-aortic balloon pump (IABP) is a recommended hemodynamic support device used in this patient population. However, there are still various opinions regarding the use of IABP. Objective: (1) To describe clinical and subclinical characteristics of patients with high-risk percutaneous coronary intervention (PCI), (2) Evaluate the role of intra-aortic balloon pump (IABP) during high-risk PCI. Materials and method: From August 2020 to October 2021, we conducted the study on 36 patient with high-risk coronary diseases in whom PCI, Among them, 16 patients underwent intervention under hemodynamic support of IABP. Results: Thirty six patients (male 66,7%) join in the study (mean age 71,81±8,52 years). Common cardiovascular risk factors were hypertention (63,9%), smoking (47,2%) and diabetes (33,3%). The mean left ventricular ejection fraction was 34±9,71%. The mean SYNTAX score was 27,39±2,96. There were no significant differences in clinical and and subclinical characteristics between the group using and not using IABP during the intervention. In IABP group, the mean blood pressure after IABP support was significantly higher than baseline (88,31±7,39 mmHg vs 77,67±7,2 mmHg, p=0,001), the mean heart rate after IABP support was significantly lower than baseline (80,75±9,84 vs 83,93±12,66, p=0,007). The group supported by IABP had a higher rate of not using vasopressors, and the rate of using 1 vasopressor drug was less than the group without IABP support, statistically significant with p<0.05. Conclusion: IABP can be use to support for high-risk PCI. Use of IABP reduces the proportion of patients requiring additional vasopressors to maintain hemodynamics.
