缩功能障碍,而不是腹缩功能障碍,显著影响ST段升高心肌梗塞 (STEMI) 后的长期结果. 这项研究发现,STEMI后左心室喷射分数 (LVEF) 损伤预测死亡率和心力衰竭住院.
科学领域:
- 心脏病学 心脏病学
- 心血管成像 - 心血管成像
- 临床结果研究研究
背景情况:
- 在ST段升高心肌梗塞 (STEMI) 之后心脏功能障碍的长期影响仍然不清楚.
- 了解缩和腹功能障碍在STEMI后的患病率和后果对于患者管理至关重要.
研究的目的:
- 为了调查STEMI后心脏功能障碍的发生率.
- 描述系统性和扩张性功能障碍与长期患者结果之间的关联.
主要方法:
- 一项涉及542名STEMI患者的DANAMI-3试验的子研究.
- 心脏磁共振 (CMR) 影像评估了在STEMI后三个月的缩功能障碍 (左心室喷射率[LVEF] < 50%) 和腹腔功能障碍 (峰值填充率/末腹腔体积[PFR/EDV] ≤ 2.55).
- 长期随访 (中位数为10.5年) 分析了所有原因死亡率和心力衰竭住院住院的复合情况.
主要成果:
- 三个月后,101名患者患有缩功能障碍,232人患有腹缩功能障碍.
- 系统性功能障碍 (LVEF < 50%) 与主要结局 (调整后危险比率[aHR] 2.73),全因死亡率 (aHR 2.26) 和心力衰竭住院 (aHR 7.87) 有显著关联.
- 扩张性功能障碍 (PFR/EDV ≤2.55) 与任何研究结果都没有关联.
结论:
- 心脏功能障碍在三个月后大约一半的STEMI幸存者中普遍存在.
- 压缩性功能障碍,独立于压缩性功能,是STEMI后不利的长期结果的重要预测因素.

Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
