概括
零对比透皮冠状动脉血管造形术 (PCI) 对慢性病 (CKD) 患者是安全的. 这种技术使用光学地标和血管内成像,避免对比介质,保护功能,并取得良好的结果.
科学领域:
- 心脏病学 心脏病学
- 腎臟病學 (nephrology) 是一種醫學.
- 干预性放射学 干预性放射学
背景情况:
- 对比诱导的脏病是皮肤穿透冠状动脉血管塑造 (PCI) 后的显著风险,特别是在患有先前存在的功能障碍的患者中.
- 血管内成像为提高这些高风险患者PCI的安全性和疗效提供了潜在的解决方案.
研究的目的:
- 在慢性病 (CKD) 患者中评估零对比性PCI的安全性和有效性.
- 评估在患有功能损害的患者中,在没有的对比剂的情况下进行PCI的可行性.
主要方法:
- 一项观察前性研究,涉及72名连续患有CKD (eGFR ≤45毫升/分钟/米2) 和确定的冠状动脉疾病 (CAD) 的患者.
- 所有程序都使用干式光镜和静脉内超声波 (IVUS) 指导进行,没有任何对比剂.
- 光学地标和IVUS被用来准确地放置支架.
主要成果:
- 72名患者 (90个血管) 的EGFR中位数为34.1毫升/分钟/1.73平方米,接受了零对照的PCI.
- 技术和程序成功率很高 (分别为91.1%和97.2%).
- 在手术后没有观察到功能恶化,在3个月的随访期间也没有出现重大不良心血管事件.
结论:
- 以光学地标和静脉内成像为指导的零对比性PCI,对于有对比性诱导脏病风险的患者来说是一种安全有效的策略.
- 这种方法可以实现良好的临床结果,在接受PCI的CKD患者中保持功能.

Cardiac Catheterization II: Right Heart Catheterization
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
Cardiac Catheterization III: Left Heart Catheterization
Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
