概括
对高出血风险患者来说,在植入瑞达福利慕斯排泄支架后,缩短双抗血小板治疗 (DAPT) 是安全有效的. 这种方法使得一年内缺血和出血事件的发生率较低.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 医疗器械 医疗器械
背景情况:
- 接受皮肤冠状动脉干预 (PCI) 的患者往往有高出血风险 (HBR).
- 药物排泄支架 (DES) 在HBR患者中优于裸金属支架,即使使用简化双抗血小板疗法 (DAPT).
- 在HBR患者中,EluNIR ridaforolimus-eluting stent在短时间DAPT的性能以前没有被评估过.
研究的目的:
- 评估在HBR患者中植入ridaforolimus-eluting支架后缩短DAPT持续时间的安全性和有效性.
- 评估心脏死亡,心肌梗塞或支架血栓形成的复合终点.
- 确定支架血栓形成和重大出血事件的发生率.
主要方法:
- 有望的,多中心的,单臂的,开放的标签试验.
- 根据LEADERS-FREE标准定义为HBR的患者.
- DAPT的持续时间:稳定性胸痛1个月,急性冠状动脉综合征1-3个月.
- 主要终点:结合1年内心死亡,心脏病发作或ARC确定的/可能的支架血栓形成.
主要成果:
- 招募了315名HBR患者,56.4%呈现急性冠状动脉综合征;33.7%接受口服抗凝药.
- 主要终点发生在4.9%的患者中,明显低于14.1%的绩效目标 (P<0.0001).
- 支架血栓 (ARC确定/可能) 发生在0.6%的患者中;BARC类型3/5出血发生在1.9%的患者中.
结论:
- 缩短的DAPT与ridaforolimus-eluting支架在HBR患者中显示出良好的安全性和有效性.
- 观察到缺血事件和支架血栓形成率较低.
- 该策略支持在高风险人群中使用利达福利慕斯释放的支架与缩写DAPT.

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors
Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.

Peripheral Artery Disease III: Interprofessional Care
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
