目的:分析药物洗脱支架(DES)术后发生极晚期支架内血栓(VLST)的患者接受双重抗血小板治疗(DAPT)的情况,探讨不同DAPT持续时间对患者远期预后的影响。方法2006年1月至2013年2月,首都医科大学附属北京朝阳医院心脏中心共完成3945例急诊冠状动脉造影,入选经急诊造影证实为VLST的患者。根据随访期间是否仍持续使用DAPT,将患者分为持续DAPT组和对照组。比较两组患者的临床资料、造影及介入治疗资料以及抗血小板药物治疗情况。临床主要不良心血管事件(MACE)包括随访期间的非致死性心肌梗死(MI),再发支架内血栓(ST),靶血管重建率(TVR)以及死亡。探讨不同DAPT持续时间对患者远期预后的影响,并分析随访期间发生MACE的预测因素。结果共计有62例VLST患者纳入研究,其中男性55例,女性7例,年龄41~82(58.6±10.2)岁。VLST距第1次DES置入时间为12.5~84(38.7±18.1)个月。住院期间脑出血死亡1例,存活的61例患者随访5~88(32.1±19.1)个月。随访期间,又有17例患者出现MACE,Kaplan-Meier生存率分析提示无事件生存率为45.1%。末次随访时,坚持持续DAPT的患者38例,其中5例(13.2%)发生MACE,事件发生率明显低于对照组(54.2%,P=0.001)。根据是否发生MACE事件将所有患者分为两组,Cox单因素分析提示再次置入第一代DES[危害率(hazard ratio,HR):2.69,P=0.04]和持续DAPT(HR:0.25,P=0.01)为远期随访中MACE相关的预测因素。而多因素Cox分析则提示仅有持续DAPT是随访期间不发生MACE的唯一预测因素(HR:0.30,95% CI:0.09~0.97,P=0.04)。结论 DES术后VLST患者远期预后情况欠佳,事件发生率较高。坚持DAPT可能有助于减少远期不良事件的发生。
目的:分析藥物洗脫支架(DES)術後髮生極晚期支架內血栓(VLST)的患者接受雙重抗血小闆治療(DAPT)的情況,探討不同DAPT持續時間對患者遠期預後的影響。方法2006年1月至2013年2月,首都醫科大學附屬北京朝暘醫院心髒中心共完成3945例急診冠狀動脈造影,入選經急診造影證實為VLST的患者。根據隨訪期間是否仍持續使用DAPT,將患者分為持續DAPT組和對照組。比較兩組患者的臨床資料、造影及介入治療資料以及抗血小闆藥物治療情況。臨床主要不良心血管事件(MACE)包括隨訪期間的非緻死性心肌梗死(MI),再髮支架內血栓(ST),靶血管重建率(TVR)以及死亡。探討不同DAPT持續時間對患者遠期預後的影響,併分析隨訪期間髮生MACE的預測因素。結果共計有62例VLST患者納入研究,其中男性55例,女性7例,年齡41~82(58.6±10.2)歲。VLST距第1次DES置入時間為12.5~84(38.7±18.1)箇月。住院期間腦齣血死亡1例,存活的61例患者隨訪5~88(32.1±19.1)箇月。隨訪期間,又有17例患者齣現MACE,Kaplan-Meier生存率分析提示無事件生存率為45.1%。末次隨訪時,堅持持續DAPT的患者38例,其中5例(13.2%)髮生MACE,事件髮生率明顯低于對照組(54.2%,P=0.001)。根據是否髮生MACE事件將所有患者分為兩組,Cox單因素分析提示再次置入第一代DES[危害率(hazard ratio,HR):2.69,P=0.04]和持續DAPT(HR:0.25,P=0.01)為遠期隨訪中MACE相關的預測因素。而多因素Cox分析則提示僅有持續DAPT是隨訪期間不髮生MACE的唯一預測因素(HR:0.30,95% CI:0.09~0.97,P=0.04)。結論 DES術後VLST患者遠期預後情況欠佳,事件髮生率較高。堅持DAPT可能有助于減少遠期不良事件的髮生。

Objective To study the application of dual antiplatelet therapy (DAPT) in the patients with very late stent thrombosis (VLST) after implantation of drug-eluting stent (DES), and to determine the effect of different durations of DAPT on long-term prognosis of these patients. Methods All of the patients with angiographically defined VLST out of 3 945 patients undergoing emergent coronary angiography in our heart center from January 2006 to February 2013 were recruited in this study. The patients were divided into 2 groups according to whether receiving continuous DAPT after implantation. The clinical data, angiographic results and interventional data were compared between the 2 groups. Major adverse cardiac events (MACE) including nonfatal myocardial infarction (MI), recurrence of stent thrombosis (ST), target vessel revascularization (TVR), and death in all causes were compared to determine the different durations of DAPT on the prognosis. Predictors of MACE during long-term follow-up were confirmed in these patients. Results Sixty-two patients were enrolled, consisting of 55 males and 7 females, with age from 41 to 82 (58.6±10.2) years. The time from first implantation of DES to occurrence of VLST was from 12.5 to 84 (38.7±18.1) months. One patient died in hospital due to cerebral hemorrhage. The other 61 patients survived to discharge, and MACE occurred in 17 patients of
<br> them during follow-up of 5 to 88 (32.1±19.1) months. Kaplan-Meier survival analysis showed the estimated MACE-free survival was 45.1%. Compared with the patients without continuous DAPT (n=24, 13/24, 54.2%), the MACE rate was obviously lower in those with continuous DAPT (n=38, 5/38, 13.2%, P=0.001). Based on the occurrence of MACE, univariate Cox analysis revealed the independent predictors for MACE-free were re-implantation of the first-generation of DES [hazard ratio (HR):2.69, P=0.04] and continuous DAPT (HR:0.25, P=0.01) during our long-term follow-up. Multivariate COX analysis indicated that continuous DAPT was the only predictor for MACE-free (HR: 0.30, 95% CI: 0.09 to 0.97, P=0.04). Conclusion Long-term outcomes for DES patients having VLST are unfavorable, with high incidence of MACE. So, continuous DAPT should be prescribed to prevent long-term MACE.
