To introduce a modified atherosclerotic ablation (RA) procedure and to study the early and medium-term outcomes of multivariate percutaneous coronary intervention (PCI) facilitating RA in group Elderly patients has a higher cardiovascular risk. Previous studies of RA outcomes have been limited to small sample sizes and low-risk populations. Method from January 2013 to November 2015, 1169 consecutive patients treated with modified RA-assisted PCI was retrospectively recruited, including new calcified lesions and restenosis in the stent. Patients were followed up regularly for at least 1 year. Major adverse cardiac events (MACEs) were analyzed for all participants according to different strategies. Cox regression analysis was performed to identify risk factors for the events. Result. The mean age of patients was 75 years, with 11.7% of patients on maintenance haemodialysis. Most lesions (99.9%) were complex (American Heart Association class B2/C) and 68.3% were treated with RA + drug-eluting stents (DES). Angiography was successful in 97.8% of cases, of which 1.7% (20/1169) cases of coronary perforation (including perforation of wires). The incidence of MACE was 20.5% and 26.8% at 1 year and 2 years of follow-up and was mainly due to target lesion revascularization (TLR) (10.3% and 12.5%, respectively. The RA + DES strategy had the lowest MACE at 2 years, compared with RA + drugcoated balloon and old RA + balloon angioplasty (14.5%, 30.5%, and 26.0%, respectively). The modified PR technique is a safe and effective tool in the modern PCI era, even in high-risk patients. TLR levels are relatively high but tolerable in these complex lesions.
