概括
埃莫里风险评分 (ERS) 准确地预测了经过透气管大动脉置换 (TAVR) 后需要永久起器 (PPM) 的需要. 这一前性验证证实了其在TAVR患者的手术前风险分层中的有用性.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 心脏外科手术 心脏外科手术
背景情况:
- 心脏起器植入是通过导管的大动脉置换 (TAVR) 后的常见并发症.
- 埃莫里风险评分 (ERS) 之前是为了预测TAVR后需要永久起器 (PPM) 植入器的需求而开发的.
- 关键的ERS指标包括史,先前存在的右束分支块 (RBBB),QRS持续时间≥140ms,假肢超大≥16%.
研究的目的:
- 为前性验证之前描述的埃莫里风险评分 (ERS) 以预测TAVR后的PPM.
- 为了评估ERS在现实世界中的性能,连续队伍使用气球可扩展假肢进行TAVR.
主要方法:
- 在2019年3月至2020年12月期间,对661名患者进行了Edwards SAPIEN 3假肢TAVR的前性评估.
- 包括没有先前存在心脏起器或节拍指示的患者.
- ERS是前性计算的,结果对临床决策是盲目的. 主要终点是30天后的PPM. 使用后勤回归,校准曲线和ROC分析来评估性能.
主要成果:
- 总共有48名患者 (7.3%) 在TAVR后需要PPM.
- 较高的ERS显著预测了PPM的可能性增加 (OR为每点2.61,p<0.001).
- ERS表现出良好的校准 (斜率=1.04) 和强大的区分能力 (ROC曲线下的面积=0.81).
结论:
- 预期 ERS 预测了在使用气球可扩展假肢进行 TAVR 的患者中需要 PPM 的需求.
- 预期ERS的表现与之前的回顾性调查结果相当.
- 在TAVR后,ERS可以作为一种有价值的工具,用于TAVR后PPM的程序前风险分层.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

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...

Mitral Valve Prolapse II: Assessment and Management

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...
