在运动回声心脏成像过程中,评估心动功能 (DF) 与心动功能一起,可以改善心脏事件的预测. 这种两步方法区分了心力衰竭和缺血事件的风险.
科学领域:
- 心脏病学 心脏病学
- 诊断成像 诊断成像 诊断成像
- 心声回声图 (Echocardiography) 是一种心声回声图.
背景情况:
- 扩张功能 (DF) 评估提高了运动心声学的预后能力.
- 一个全面的方案,评估缩和腹功能可以预测各种心脏事件.
研究的目的:
- 为了评估运动心声学期间综合缩和腹缩功能评估的预后价值.
- 为了确定这个两步方案能否区分心力衰竭/心血管死亡和缺血事件.
主要方法:
- 对2519名患者进行了运动回声心脏成像,评估了运动高峰时的左心室静脉功能和运动后的E / e' / 静脉肺压.
- 异常的缩功能被定义为缺血或固定壁运动异常;异常的DF被定义为运动后 E/e' > 15.
- 这项研究分析了心力衰竭/心血管死亡 (CF/CVD) 和缺血事件的系统和DF预测值.
主要成果:
- 在32%的患者中发现了静缩异常,在18%的患者中发现了静缩异常.
- 运动后异常的DF在CF/CVD患者 (48%) 与缺血事件 (27%) 相比更为常见,而缺血组 (78%) 的缩异常更高.
- 独立预测因素包括 Δ 墙壁运动得分指数 (对于整体事件) 和运动后 E/e' (对于CF/CVD). 缩功能预测了缺血事件,而DF预测了CF/CVD.
结论:
- 一个两个步骤的运动回声心脏图谱协议,评估缩和放缩功能,有效地预测不同类型的心脏事件.
- 仅仅依赖于缩功能评估的运动回声心脏成像可能不包括心脏异常和相关风险的全部范围.

Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Exercise Stress Test
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.
Purposes
