Abstract:
Objective To evaluate the efficacy and safety of Paclitaxel drug coated balloon (DCB) (SeQuent Please) in an elderly patients with de novo coronary disease.Methods We performed a retrospective study of 158 consecutive patients (63 patients aged ≥65 yrs and 95 patients aged ＜65 yrs) received DCB therapy in Cath Lab of Beijing Hospital.Clinical characteristic was recorded and coronary angiography was analyzed with quantitative coronary angiography (QCA) software.Results In elderly group,more patients have hypertension (65.1％ vs.56.8％),atrial fibrillation (7.9％ vs.2.1％),previous percutaneous coronary intervention (PCI) history (44.4％ vs.23.2％,P＜0.01) and non ST-elevated myocardial infarction (NSTEMI) (14.3％ vs.4.2％,P ＜0.05).In non-elderly group,more patients were male (71.6％ vs.50.8％,P＜0.05) and current smoker (52.3％ vs.30.2％,P＜ 0.01).Old patients had more complicated lesions,especially calcified lesions (36.8％ vs.14.0％,P＜0.01).Despite of that,our study showed a higher success rate of PCI in elderly group.Both groups of patients showed significant acute gain in minimal lumen diameter (MLD) after DCB released.At 4 days post-operation,there was one case that underwent acute myocardial infarction requiring emergent target lesion revascularization (TLR) in non-elderly group.No major adverse cardiac event (MACE) was observed in the elderly group during hospitalization.Twenty-one patients underwent coronary angiographic followed up at average 9 months post PCI.The QCA analysis showed that MLD of lesions treated with DCB had mildly increased [(2.00±0.67) mm vs.(1.91 ± 0.47) mm,P＞0.05],the late lumen loss (LLL) was (-0.09±0.50) mm.At 9 months follow-up,the MACE rate in the elderly group was 1.6％ and 1.1％ in non-elderly group,with TLR rates at 0.0％ and 1.1％ respectively (both P＞0.05).No death was observed in either group.Conclusions The efficacy and safety of DCB on the elderly patients with de novo lesions is as good as non-elderly patients despite more complex anatomy and comorbidities.
