概括
在内血管动脉瘤支架后,将克洛皮多格雷尔不响应者切换到蒂卡格雷勒是安全的. 这种个性化抗血小板方法与克洛皮多格雷尔反应者相比,产生类似的血栓栓栓塞并发症率,支持例行血小板功能测试.

- 血栓塞栓并发症是内血管动脉瘤支架的重要风险.
- 克洛皮多格雷尔耐药性是导致这些并发症的主要因素.
- 在克洛皮多格雷尔不响应患者中提卡格雷罗的疗效需要评估.
研究的目的:
- 评估克洛皮多格雷尔耐药患者进行内血管动脉瘤支架的血栓栓塞结局.
- 评估转换为提卡格勒罗是否会减轻非响应者的风险.
主要方法:
- 228名患者 (2020-2024) 的单中心回顾性队列研究.
- 前程序P2Y12对血小板功能进行测试.
- 克洛皮多格雷尔无反应者 (<40%的抑制) 被切换到蒂卡格雷罗.
- 主要终点:血栓栓塞并发症 (放射性或临床心脏病发作).
主要成果:
- 54% (122/228) 的患者是克洛皮多格雷尔无反应者,并转换为提卡格雷罗.
- 在克洛皮多格雷尔反应者 (13%) 和提卡格雷勒不反应者 (11%) 之间,临床心脏病发作率没有显著差异.
- 在放射性心脏病发作率中,两组之间没有显著差异 (19%对12%).
- 更大的动脉瘤大小与增加的放射性和临床心脏病发作相关.
结论:
- 在非响应者中进行手术前的血小板功能测试和切换到蒂卡格勒罗,导致可比的血栓栓塞并发症率.

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors
1.4K
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
457
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...

Aneurysm IV: Nursing Management
554
Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Aneurysm III: Interprofessional Care
414
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
