概括

与血管造影相比,定量流量比率 (QFR) 的指导并没有显著改善中间冠状动脉病变的2年结果. 对FAVOR III中国试验的分析发现,在QFR指导干预中,对主要心脏不良事件没有重大益处.

科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
医疗成像医学成像

背景情况:

中国的FAVOR III试验显示,定量流量比率 (QFR) 引导的皮肤冠状动脉干预 (PCI) 比血管造影有好处.
关于QFR在中间病变 ("不确定性区域") 的疗效存在不确定性.
这项研究研究了QFR与血管学指导在这些特定的病变.

研究的目的:

评估QFR引导PCI与血管学引导PCI对患者管理和结果的影响.
专门分析患有"不确定区"冠状动脉病变的患者的结果.

主要方法:

在FAVOR III中国试验中预先规定的子组分析.
确定了873名患者 (22.9%) 患有不确定性区域病变 (离线QFR0.75-0.85).
在QFR指导和血管学指导的PCI组之间,在2年内比较主要的不良心脏事件 (MACE).

主要成果:

在2年后,MACE发生在QFR组的7.0%和血管造影组的8.3% (HR 0.85).
里程碑式的分析表明,在1年之前和1年后的治疗效果不同 (P_相互作用=0.03).
根据QFR指导,1年后出现好处,主要原因是心肌梗塞和血管再循环减少.

结论:

在这组中介性冠状动脉病变患者中,QFR引导的重血管化并没有显著改善2年临床结果.
这些发现表明,在FAVOR III中国整体试验中观察到的好处可能不适用于这个特定的患者亚组.

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
