概括
在高出血风险 (HBR) 患者的皮肤冠状动脉干预 (PCI) 使用定制策略是安全的. 简化双重抗血小板治疗 (DAPT) 和减血技术改善了结果,特别是在高缺血风险人群中.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 血管医学 血管医学
背景情况:
- 高出血风险患者的皮肤冠状动脉干预 (PCI) 构成了重大的临床挑战,需要在预防缺血事件和最大限度地减少出血并发症之间保持微妙的平衡.
- 学术研究联盟高出血风险 (ARC-HBR) 标准有助于识别HBR患者,但最佳时间,程序策略和抗血栓策略仍然不清楚.
研究的目的:
- 审查和综合目前关于HBR患者PCI的证据,重点关注程序策略和抗血栓治疗方案.
- 在各种临床场景中评估不同PCI方法和治疗时间在HBR群体中的安全性和有效性.
主要方法:
- 对随机对照试验,大型注册表和涉及接受PCI的HBR患者的元分析进行了全面的审查.
- 分析了有关程序选择 (辐射与股骨接触),设备选择 (涂药气球,无聚合物药物排泄支架) 和双抗血小板治疗 (DAPT) 持续时间的数据.
- 在不同的临床环境中检查PCI时间策略,包括稳定的冠状动脉疾病,急性冠状动脉综合征 (ACS),ST升高心肌梗塞 (STEMI) 和特定高风险状态.
主要成果:
- 有证据支持将缩短的DAPT疗程 (1-3个月) 与节血技术和设备相结合,对高缺血负担的患者尤其有益 (例如,GRACE评分>140).
- 在接受PCI的ACS患者中,早期的侵入性治疗与减少缺血事件和在没有增加大出血的情况下更短的住院时间有关.
- 推迟PCI推给有活跃出血,最近发生血栓溶解或严重凝血病的患者.
结论:
- 在HBR患者中,PCI可以通过个性化,基于证据的程序定时和抗血栓治疗策略,安全有效地进行.
- 局限性包括ARC-HBR患者在临床试验中的代表性不足,以及缺乏标准化协议,以根据出血风险量身定制的PCI时间.
- 未来的研究应该专注于整合生物标记驱动的DAPT调制和人工智能,以优化这一高风险人群的结果.

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
