Angiopoietin-1 (Ang-1) and angiopoietin-2 (Ang-2) play divergent roles in myocardial ischemia and reperfusion injury.
To investigate serum Ang-1 and Ang-2 levels in ST-segment elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PCI).
Serum Ang-1 and Ang-2 were measured in 85 STEMI patients in the first week after PCI.
Ang-1, Ang-2 and Ang-2/Ang-1 ratio (Ang-2/1) were all increased at admission, and had dynamic changes after PCI. Ang-2 and Ang-2/1 at admission and 2 h after PCI were positively correlated with peak cardiac troponin T levels.
The extent of myocardial damage may be linked to circulating Ang-2 and Ang-2/1.
血管生成素-1（Ang-1）和血管生成素-2（Ang-2）在心肌缺血再灌注损伤中发挥不同的作用。
研究经皮冠状动脉介入治疗（PCI）治疗的 ST 段抬高型心肌梗死（STEMI）患者的血清 Ang-1 和 Ang-2 水平。
在 PCI 后第一周测量了 85 例 STEMI 患者的血清 Ang-1 和 Ang-2。
Ang-1、Ang-2 和 Ang-2/Ang-1 比值（Ang-2/1）在入院时均升高，并在 PCI 后发生动态变化。入院时和 PCI 后 2 小时的 Ang-2 和 Ang-2/1 与肌钙蛋白 T 峰值水平呈正相关。
心肌损伤的程度可能与循环 Ang-2 和 Ang-2/1 有关。
