Impact of paclitaxel-coated balloon versus newer-generation drug-eluting stent on periprocedural myocardial infarction in stable angina patients

초록

ObjectivesPeriprocedural myocardial infarction (PMI) is reported to be associated with adverse long-term clinical outcomes. This study compared the rates of PMI following treatment of de novo coronary lesions using either a paclitaxel-coated balloon (PCB) or a newer-generation drug-eluting stent (DES).Patients and methodsWe compared the incidence of PMI in propensity-matched patients with stable angina pectoris and single-vessel de novo coronary lesions who underwent treatment with a PCB or newer-generation DES. Propensity score matching was performed to adjust for differences in baseline clinical and angiographic characteristics.ResultsAfter propensity matching, the study cohort included 108 patients (PCB: n=54 and DES: n=54). The peak mean values of creatine kinase-myocardial band (13.326.3 vs. 2.2 +/- 2.8ng/ml, P=0.003) and high-sensitive troponin T (0.62 +/- 1.38 vs. 0.09 +/- 0.19ng/ml, P=0.007) were significantly higher in the DES group compared with the PCB group. The incidence of PMI was significantly higher in the DES group [DES: 11 (20.4%) vs. PCB: one (1.9%); P=0.002]. Total occlusion of the side-branch occurred in two patients treated with DES, but no patients treated with PCB. Treatment with a newer-generation DES was found to be an independent predictor of PMI on multivariable analyses.ConclusionIn patients with stable angina using a PCB, compared with deployment of a newer-generation DES, is associated with a significant reduction in the risk of PMI.
