概括

在慢性全闭性皮肤冠状动脉干预 (PCI) 中,自我施加的药物排泄支架 (DES) 减少了支架错位和未覆盖的支架. 然而,它们与主要不良心血管事件 (MACE) 的增加有关,这是由于目标病变的重血管化.

科学领域:

干预心脏病学干预心脏病学
生物材料科学生物材料科学
血管生物学血管生物学

背景情况:

慢性全封闭 (CTO) 穿皮冠状动脉干预 (PCI) 是具有挑战性的,通常与不完整的支架支架插座和覆盖相关.
与传统的气球可扩展 (BE) 支架相比,自贴 (SA) 支架为这些问题提供了潜在的解决方案.

研究的目的:

在CTO PCI中评估SA支架与BE支架的12个月血管学和临床结果.
为了比较SA-DES和BE-DES之间的支架错位和覆盖范围.
评估12个月内主要不良心血管事件 (MACE) 的发生率.

主要方法:

一项试点研究将20名用SA药物释放支架 (DES) 治疗的患者与20名对应的对照人进行了比较,这些人接受了CTO PCI的BE-DES治疗.
12个月的临床随访,随访时进行冠状动脉血管学和光学连贯性断层扫描 (OCT).
主要终点:支架支架错位和覆盖范围. 二级终点:12个月后的复合MACEs.

主要成果:

在SA-DES组显示,在12个月后,错位的支架率 (0%vs4.5%) 和未覆盖的支架率 (0.08%vs8.2%) 显著降低.
尽管支架覆盖率有所改善,但SA-DES组的MACE发病率更高 (45%与15%相比),主要是由于临床驱动的瘤重血管化.
两组人都有复杂病变和糖尿病的高患病率.

结论:

与BE-DES相比,在CTO PCI中自叠加的DES与优越的支架支架叠加和覆盖率有关.
然而,在这种情况下,SA-DES与显著更高的静脉静脉复缩和MACE发病率有关.
这些发现表明,在复杂的CTO PCI中,改善支架部署和不良的临床结果之间存在潜在的权衡.

关键词:

慢性完全闭塞慢性完全闭塞实体静脉复缩 (英语:In-stent restenosis) 是一种体内静脉复缩.晚期的错误对立是晚期的错误对立.光学连贯性断层扫描技术.这是一种自我施加的支架.

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...
