Critical Left Ventricular Ejection Fraction and Its Possible Pathogenesis in STEMI Patients with Supra-normal Ejection Fraction after Primary PCI [PDF]
, 2022 BackgroundLeft ventricular ejection fraction (LVEF) is often used as an assessment indicator for left ventricular systolic function. As adverse events occur in some patients with preserved LVEF, other phenotypes based on LVEF may exist in the population ...

酷似急性心肌梗死的Takotsubo 综合征临床特点及预后分析 [PDF]
, 2020 目的探讨Takotsubo 综合征的临床特点，影像学特征及预后，避免漏诊、误治，及时采取正确的治疗手段。方法回顾性分析10例酷似急性心肌梗死的Takotsubo 综合症综合征（TTS）的病例资料及转归。结果10 例TTS患者的心电图均表现为ST段抬高及后期较大的动态改变；男女比例1：9，年龄49~83岁。实验室检查提示cTn水平轻中度升高，但NT-proBNP明显升高伴有左心室功能障碍。10例均行冠脉造影未发现冠脉明显病变，但4例出现慢血流，其中9例行左室造影明确TTS；1例因低血压行IABP ...
