概括
在J-CTO的得分.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 血管生物学 血管生物学
背景情况:
- 该J-CTO得分用于预测慢性全闭症 (CTO) 再通道化的成功.
- 它在实体CTO干预中与de novoCTO相比的实用性尚未得到充分证明.
研究的目的:
- 为了比较J-CTO得分在预测程序成功和指导线穿越时间方面的有效性,用于in-stent与de novo CTO干预.
- 为了在这些比较中评估基于电线的板内跟踪技术在这些比较中的作用.
主要方法:
- 对508名接受CTO再通道治疗的患者进行了回顾性分析.
- 患者被分为内置的CTO (N=74) 和新的CTO (N=434) 组.
- 评估了J-CTO评分的程序可行性和指导线穿越时间,使用内跟踪.
主要成果:
- 对于具有J-CTO分数≥3 (85%) 的新任CTO,与≤2 (97%,p < 0.001) 相比,程序成功率显著下降.
- 然而,实体CTO的成功率在J-CTO分数中是可比的 (≥3: 96%对 ≤2: 100%,p = 0.400).
- 较长的导线穿越时间 (≥30分钟) 在静脉CTO中较少 (OR=0.40). 粗的茎和闭塞长度≥20mm是干支CTO穿越时间的独立因素.
结论:
- 对于程序可行性和导线穿越时间,J-CTO评分对程序可行性的影响在实体和新型CTO之间有所不同.
- 在即时CTO干预中,应谨慎解释J-CTO评分.
- 内板导线跟踪技术为这些差异提供了洞察力.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
395
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

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...
