概括

手术性心肌梗塞 (pMI) 和自发性心肌梗塞 (spMI) 都会增加1年死亡率,特别是热素峰值超过35倍的时间. 对于较低的热素升高 (≤35xURL),只有spMI显著影响死亡率.

科学领域:

心脏病学心脏病学
心血管医学心血管医学
干预心脏病学干预心脏病学

背景情况:

程序性心肌梗塞 (pMI) 与自发性心肌梗塞 (spMI) 的预后影响尚不清楚.
了解差异性死亡风险对于患者管理至关重要.

研究的目的:

为了比较pMI和spMI后的一年全因死亡率.
评估热素水平升高对死亡风险的影响.

主要方法:

对10707名接受皮肤穿冠状动脉干预 (PCI) 的患者进行了回顾性分析.
在慢性冠状动脉综合征 (CCS) 患者中,定义的pMI是PCI后热激素增加>1xURL.
定义spMI为急性冠状动脉综合征与升高的热素;评估的死亡率在热素层.

主要成果:

一年死亡率在pMI (7.7%) 和spMI (8.5%) 中较高,热素峰值>35xURL,与没有MI (1.4%) 相比.
在pMI或spMI后,升的热素 (>35倍的URL) 显著增加了死亡风险 (aHR分别为4.40和7.57).
只有spMI显示了高于1-5x和>5-35xURL的热素峰值的死亡率增加.

结论:

具有显著的热素升高 (>35倍URL) 的pMI和spMI都导致1年死亡率增加.
对于高达URL的35倍的托罗邦素升高,spMI比pMI具有更大的死亡风险.
