应激性心肌病临床研究

Clinical Research on Stress Cardiomyopathy

应激性心肌病是一类在心理应激或躯体应激的情况下发生的可逆性急性左心室心尖部球样扩张,从而导致心室功能障碍的疾病。心室异常扩张主要发生在左心室,也有少数累及右心室。临床有典型胸痛、呼吸困难症状、心电图可出现ST-T动态变化、心肌酶等可轻度升高、但冠状动脉造影没有明确的冠状动脉闭塞性病变,而且左室功能障碍在数天或数周内恢复正常。多数患者预后良好,但在急性期也可能会因心源性休克、心室颤动、急性肺水肿、心脏破裂而导致患者死亡,且有复发的可能性。

Stress cardiomyopathy is a type of disease that occurs in the case of psychological stress or physical stress,and reversible acute left ventricular apical spheroid expansion leading to ventricular dysfunction.Abnormal ventricular dilatation mainly occurs in the left ventricle,and a few involve the right ventricle.Clinical symptoms of typical chest pain and dyspnea;ST-T dynamic changes can occur in ECG;myocardial enzymes can be slightly elevated;but coronary angiography has no clear coronary occlusive disease,and left ventricular dysfunction in days or counts It returned to normal within the week.Most patients have a good prognosis,but in the acute phase,patients may die due to cardiogenic shock,ventricular fibrillation,acute pulmonary edema,and cardiac rupture,and there is a possibility of recurrence.
