概括
对于冠状动脉 (CAS) 的右冠状动脉 (RCA) 的常规评估至关重要. 仅对左冠状动脉 (LCA) 进行评估可能会错过高达三分之一的CAS病例,这凸显了多血管测试的重要性.
科学领域:
- 心脏病学 心脏病学
- 诊断成像 诊断成像 诊断成像
- 干预心脏病学 干预心脏病学
背景情况:
- 冠状动脉 (CAS) 诊断通常依赖于使用乙胆 (ACh) 的侵入性挑测试.
- 目前的协议通常评估左冠状动脉 (LCA),但由于程序复杂性,往往省略右冠状动脉 (RCA).
- 这项研究调查了在多血管测试期间LCA和RCA中可诱导CAS的患病率.
研究的目的:
- 为了比较可诱导CAS在LCA与RCA中的发生率.
- 通过仅评估LCA来确定错过的CAS案件的比例.
- 倡导在CAS挑测试中进行常规RCA评估.
主要方法:
- 分析了多机构ANOCA数据库,其中包括316名疑似CAS.患者.
- 50名患者接受了多血管刺激测试,用冠心内冠状动脉 (LCA:25,50,100μg;RCA:25,50μg).
- 在血管造影上,CAS被定义为>90%的心上冠状动脉收缩.
主要成果:
- 在接受多血管检测的50名患者中,40% (20名患者) 具有可诱导的CAS.
- 在45%的病例中,ACH仅在LCA中引起CAS,在35%的病例中仅在RCA中引起CAS,在20%的病例中仅在两个容器中引起CAS.
- 这表明35%的多船舶CAS案件仅限于RCA.
结论:
- 在ACH挑测试期间对RCA的常规评估对于全面的CAS诊断至关重要.
- 从测试中排除RCA可能导致诊断不足,可能错过高达三分之一的CAS病例.
- 包括RCA在内的多血管刺激测试可以提高冠状动脉的诊断准确性.

Exercise Stress Test

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
