卒中是心房颤动的严重并发症。以往的预防措施包括口服阿司匹林和抗凝药。对不适合口服抗凝药的患者可以采用阿司匹林和氯吡格雷的联合治疗。但这种联合治疗在降低卒中风险的同时,却增加了出血的风险。对于心房颤动合并有不稳定型冠脉综合征者,或接受冠状动脉支架治疗,但又不适合接受三联治疗(阿司匹林、氯吡格雷、华法林)的患者,该中心采用阿司匹林和氯吡格雷。对于冠状动脉支架手术,要求介入专家优先考虑采用裸金属支架,以缩短患者依赖联合治疗的时间。 相似文献

目的:讨论长期口服抗凝剂患者冠状动脉支架术后的抗栓治疗方案。方法:选择长期口服华法林钠,并在北京安贞医院接受冠状动脉造影(CA)和支架术(PCI)的患者,对临床资料进行回顾性分析,根据患者出院用药方案进行分组,比较组间基线特征,以及支架术后再梗死、死亡、脑梗死及出血等事件之间的差别。结果:符合要求的90例患者分为华法林钠+氯吡格雷+阿司匹林三联治疗组(A组)、华法林钠+氯吡格雷二联治疗组(B组)、阿司匹林+氯吡格雷二联治疗组(C组)。最常用治疗方案是停用华法林钠,联用阿司匹林和氯吡格雷。3个治疗组患者的再梗死、死亡、脑血管意外、严重出血及输血治疗等差异无统计学意义。结论:高危血栓栓塞风险患者冠状动脉支架术后应予三联治疗,密切监测凝血酶原时间(PT)和国际标准化比值(INR);而对于低危血栓栓塞风险的患者停用华法林钠,联用阿司匹林和氯吡格雷的治疗方案是可行的。本项调查观察样本量小,证据不够充分。针对不同患者制定相应的抗栓治疗方案,才能在获得良好抗栓疗效的同时减少出血事件。 相似文献

Dual antiplatelet therapy of aspirin and a thienopyridine is the standard of care following coronary stenting. Patients who are on chronic warfarin therapy and receive a coronary stent need to be treated with the triple therapy of aspirin, clopidogrel and warfarin; however, the bleeding risk in these patients is unknown. To evaluate the bleeding risk in patients requiring chronic warfarin therapy and undergoing stent implantation, we compared 107 consecutive patients on chronic warfarin therapy who underwent coronary stenting and were discharged on aspirin, clopidogrel and warfarin to 107 contemporary patients who were treated with aspirin and clopidogrel. We evaluated their bleeding history before and after coronary stenting. Major bleeding was defined as bleeding that was significantly disabling, intraocular or requiring at least 2 units of blood transfusion. Minor bleeding was defined as other bleeding that led to interruption of the medications. Patients on triple therapy were younger and more likely to have hypertension. This group had significantly higher major bleeding (6.6% vs. 0%; p = 0.03) and minor bleeding (14.9% vs. 3.8%; p = 0.01) compared with the dual antiplatelet therapy group. In the triple therapy group, the international normalized ratio or aspirin dosage did not influence the bleeding risk. In patients requiring warfarin therapy, the addition of dual antiplatelet therapy is associated with an approximately 7% major bleeding risk. Thus, novel regimens are needed to reduce the bleeding risk. 相似文献

Objectives. Optimal antithrombotic/anticoagulation therapy in patients on chronic oral anticoagulation (OAC) undergoing drug‐eluting stent (DES) implantation is unknown. We investigated the efficacy and safety of two regimens of antithrombotic/anticoagulation therapy in patients who present for DES implantation whilst on OAC. Methods. We included a series of 515 patients on OAC who underwent DES implantation between 2002 and 2007. Based on predefined clinical and echocardiographic criteria, 306 patients continued OAC (triple therapy) and 209 patients discontinued OAC (dual therapy) for the time they received antiplatelet therapy with clopidogrel and aspirin [stent‐related antithrombotic treatment (SRAT)]. The primary end point was a composite of death, myocardial infarction, stent thrombosis or stroke. Results. During SRAT the primary endpoint was observed in 13 patients in the group with triple therapy versus 15 patients in the group with dual therapy [Kaplan–Meier estimates 4.2% and 7.2%, odds ratio (OR) = 0.61, 95% confidence interval (CI) 0.29–1.28; P = 0.19]. At 2 years of follow‐up, the primary endpoint was observed in 35 patients in the group with triple therapy versus 36 patients in the group with dual therapy (Kaplan–Meier estimates 14.1% and 18.0%, OR = 0.76, 95% CI: 0.48–1.21; P = 0.25). Two‐year incidence of major bleeding was 1.4% (n = 4, triple therapy) versus 3.1% (n = 6, dual therapy) (P = 0.34). Conclusions. In patients on chronic OAC undergoing DES implantation, clinical and echocardiographic criteria help to define postprocedural antithrombotic/anticoagulation therapy. Based on these criteria, both a double antiplatelet therapy (clopidogrel plus aspirin) and a triple therapy (OAC plus clopidogrel plus aspirin) are associated with favourable safety and efficacy. 相似文献

Antithrombotic management of patients with atrial fibrillation (AF) undergoing coronary stenting is complicated by the need for anticoagulant therapy for stroke prevention and dual antiplatelet therapy for prevention of stent thrombosis and coronary events. Triple antithrombotic therapy, typically comprising warfarin, aspirin, and clopidogrel, is associated with a high risk of bleeding. A modest‐sized trial of oral anticoagulation with warfarin and clopidogrel without aspirin showed improvements in both bleeding and thrombotic events compared with triple therapy, but large trials are lacking. The RE‐DUAL PCI trial (NCT 02164864) is a phase 3b, a strategy of prospective, randomized, open‐label, blinded‐endpoint trial. The main objective is to evaluate dual antithrombotic therapy with dabigatran etexilate (110 or 150 mg twice daily) and a P2Y12 inhibitor (either clopidogrel or ticagrelor) compared with triple antithrombotic therapy with warfarin, a P2Y12 inhibitor (either clopidogrel or ticagrelor, and low‐dose aspirin (for 1 or 3 months, depending on stent type) in nonvalvular AF patients who have undergone percutaneous coronary intervention with stenting. The primary endpoint is time to first International Society of Thrombosis and Hemostasis major bleeding event or clinically relevant nonmajor bleeding event. Secondary endpoints are the composite of all cause death or thrombotic events (myocardial infarction, or stroke/systemic embolism) and unplanned revascularization; death or thrombotic events; individual outcome events; death, myocardial infarction, or stroke; and unplanned revascularization. A hierarchical procedure for multiple testing will be used. The plan is to randomize ~ 2500 patients at approximately 550 centers worldwide to try to identify new treatment strategies for this patient population. 相似文献

Antiplatelet therapy with aspirin and clopidogrel is standard care following revascularization by percutaneous coronary intervention with stent insertion. This so-called dual therapy is recommended for up to 4 weeks after intervention for bare-metal stents and for 6-12 months after intervention for drug-eluting stents. Although it is estimated that 5% of patients undergoing percutaneous coronary intervention require long-term anticoagulation because of an underlying chronic medical condition, continuing treatment with triple therapy (warfarin, aspirin and clopidogrel) increases the risk of bleeding. In most patients triple antithrombotic therapy seems justified for a short period of time. In some patients, however, a more considered judgment based on absolute need for triple therapy, risk of bleeding and risk of stent thrombosis is required, but the optimum antithrombotic treatment for these patients who require long-term anticoagulation has not been defined. This Review summarizes the existing literature concerning antithrombotic therapy and makes recommendations for initiation and duration of triple therapy in the small proportion of patients already receiving anticoagulant therapy who require percutaneous coronary intervention. 相似文献

OBJECTIVES: The optimal antithrombotic treatment for patients on long-term anticoagulation undergoing invasive coronary procedures is currently undefined. The strategies adopted periprocedurally and medium-term after coronary stenting (percutaneous coronary intervention with stent implantation) at our Institution, were reviewed, and the safety and efficacy of the various regimens evaluated. METHODS: All patients undergoing invasive coronary procedures between January 2002 and December 2004 were retrospectively identified. RESULTS: Out of 3709 patients overall, 104 (2.8%; 95% confidence interval 2.3-3.4) were on warfarin (because of atrial fibrillation in >50% of cases), whereas this was the case for 49 (3.1%; 95% confidence interval 2.3-4.1) of 1584 undergoing percutaneous coronary intervention with stent implantation. The antithrombotic strategies were highly variable, both periprocedurally (i.e. warfarin withdrawal or substitution by heparin, followed by aspirin with or without a thienopyridine) and medium-term after percutaneous coronary intervention with stent implantation (i.e. combination of warfarin and single or dual antiplatelet agents or pure dual antiplatelet treatment). Overall, periprocedural hemorrhages occurred in five patients (4.8%; 95% confidence interval 1.56-11.22). No thromboembolic events were observed, whereas one subacute stent thrombosis occurred (2%; 95% confidence interval 0.05-11) during warfarin and aspirin treatment. Among patients undergoing percutaneous coronary intervention with stent implantation, 1-month hemorrhagic rate was 10% (95% confidence interval, 3.3-23.8); most hemorrhages (major bleeds in three-quarters of cases) occurred during triple therapy with warfarin (or low-molecular-weight heparin), aspirin and a thienopyridine. CONCLUSIONS: At our Institution (where standardized protocols are currently not in use), periprocedural and medium-term antithrombotic treatment in patients on long-term anticoagulation undergoing percutaneous coronary intervention with stent implantation showed substantial variability. As a result of the relevant 1-month complication rate, further properly sized and designed studies are warranted to identify the optimal strategies for this patient subset, which is foreseen to progressively increase over the next years. 相似文献

Background
Dual antiplatelet therapy with aspirin and clopidogrel has replaced aspirin and systemic anticoagulation with warfarin as the preferred antithrombotic therapy after percutaneous coronary intervention (PCI) with stent placement. However, a number of patients have indications for all 3 drugs. We sought to determine the frequency and type of hemorrhagic complications in patients who undergo systemic anticoagulation with warfarin while receiving aspirin and clopidogrel after a PCI with stent placement.Methods
We performed a retrospective analysis of the Mayo Clinic PCI database and identified 66 consecutive patients who were discharged from hospital after PCI between January 2000 and August 2002 (inclusive) receiving a combination of dual antiplatelet therapy (aspirin and clopidogrel) and systemic anticoagulation (warfarin) to determine the incidence of bleeding and other clinical events during the treatment period.Results
Six patients (9.2%; 95% CI, 3.5-19.0) reported a bleeding event; 2 patients required a blood transfusion. No patient died or sustained a myocardial infarction or stent thrombosis.Conclusions
The risk of bleeding may be increased in patients treated with aspirin, a thienopyridine, and warfarin early after PCI with stent placement. 相似文献19.

The purpose of this study was to determine the effect of the addition of cilostazol to aspirin plus clopidogrel on platelet aggregation after intracoronary stent implantation. Twenty patients who underwent coronary stent placement were randomly assigned to therapy with aspirin plus clopidogrel (dual-therapy group, n = 10) or aspirin plus clopidogrel plus cilostazol (triple-therapy group, n = 10). A loading dose of clopidogrel (300 mg) and cilostazol (200 mg) was administered immediately after stent placement, and clopidogrel (75 mg/day) and cilostazol (100 mg twice daily) were given for 1 month. Platelet aggregation in response to adenosine diphosphate (ADP; 5 and 20 micromol/L) or collagen and P-selectin (CD-62P) expression was assayed at baseline, 2 hours, 24 hours, 1 week, and 1 month after stent placement. Inhibition of ADP-induced platelet aggregation was significantly higher in patients receiving triple therapy than those receiving dual therapy from 24 hours after stent placement, and inhibition of collagen-induced platelet aggregation was significantly higher in the triple-therapy group beginning 1 week after stent placement. P-Selectin expression was significantly lower in the triple-therapy than dual-therapy group at 1 week and 30 days. In conclusion, compared with dual antiplatelet therapy, triple therapy after coronary stent placement resulted in more potent inhibition of platelet aggregation induced by ADP and collagen. These findings suggest that triple therapy may be used clinically to prevent thrombotic complications after coronary stent placement. 相似文献
