Objective: This paper analyses patients with coronary artery bifurcation lesions undergoing percutaneous coronary intervention (PCI) with active vascular graft protection to explore the efficacy of this technique in patients with coronary artery bifurcation lesions.

Methods: The surgical data of the two groups were collected and compared. The SF-36 health status questionnaire was used to evaluate the quality of life of patients before and after 6 months of follow-up. The incidence of vascular occlusion, restenosis and MACE were followed up 6 months after the operation.

Results: The operation time of the experimental group was 57.4±18.8 s, the amount of contrast agent was 91.6±23.7 ml, the ratio of no-reflow in the intraoperative branch was 2.00% and the number of sacral extensions in the branch was 4.00%; all these values were significantly lower than in the control group. In the control group, the corresponding values were 76.3±25.4 s, 121.5±30.9 ml, 13.04% and 23.91%, respectively (P<0.05). The quality-of-life scores of the postoperative group were significantly higher than those of the control group (P<0.05). Additionally, 6 months after the operation, the rate of restenosis of the side branch vessels was 6.00% and the incidence of MACE major events was 4.00% in the postoperative group, significantly lower than the corresponding values of 19.57% and 17.39%, respectively, in the control group (P<0.05).

Conclusion: The active balloon protection technique of the side branch vessels can reduce the incidence of postoperative bilateral haemorrhagic restenosis and MACE events in patients with coronary artery bifurcation lesions treated with PCI and effectively improve the quality of life and prognosis of patients, making it worthy of clinical application.
