Abstract:Objective To investigate the clinical efficacy of percutaneous coronary rotational atherectomy (PTCRA) combined with percutaneous coronary intervention (PCI) in the treatment of coronary heart disease (CHD) and its effect on vascular injury and long-term restenosis. Methods From July 2014 to June 2017, a total of 107 CHD patients who underwent PCI operation were retrospectively analyzed. Patients underwent PTCRA were divided into PTCRA group (62 patients), and the others were divided into the control group (45 patients). On the same basic treatment measures, the clinical efficacy of the two groups was compared. Results Compared with the control group, the number, rotational average diameter, average length of stents in PTCRA group were not statistically different (P?> 0.05). The success rate of PTCRA group was 98.39% compared with 95.56% of the control group, the difference was not statistically significant (P?>?0.05). The difference of preoperative lesion vessel diameter and vascular stenosis rate between the two groups was not statistically significant (P?>?0.05); after operation, the difference between the two groups was statistically significant (P?>?0.05). The diameter of diseased vessels in PTCRA group was larger than that in control group, and the rate of vascular stenosis was lower than that in control group; the vascular injury rate of PTCRA group was 6.45% compared with 4.44% of control group, the difference was not statistically significant (P?>?0.05); the incidence of major adverse cardiovascular events (MACE) was 6.45% in PTCRA group and 20.00% in control group at 6 months after operation, and the difference was statistically significant (P?0.05). The 2-year heart disease-free survival rate was (71?±?7)%; the 2-year target vessel revascularization rate (TVR) was (19.3?±?7.0)%. Conclusion PTCRA combined with PCI reduces the restenosis rate after surgery and the incidence of postoperative MACE in treating patients with CHD, without increasing vascular injury.
