[Subarachnoid hemorrhage complicated with different manifestations of transient abnormal left ventricular wall motion: two case reports].

Two patients with subarachnoid hemorrhage presented with transient abnormal left ventricular wall motion. Case 1 was a 56-year-old man. Electrocardiography showed ST segment elevation in leads I, II, II, aVL, aVF, V3-V6. Echocardiography showed localized left ventricular hypokinesis around the apical area (takotsubo-like cardiomyopathy). Ejection fraction was 20% (1st hospital day). Troponin T was positive. Case 2 was a 48-year-old woman. Electrocardiography showed ST segment elevation in leads I, aVL, V2-V6 and ST segment depression in leads II, III, aVF, V1. Echocardiography showed diffuse left ventricular hypokinesis. Ejection fraction was 21% (1st hospital day). Troponin T was positive. These two patients had no history of cardiac disease, and coronary angiography showed no stenosis or obstruction. Catecholamine was given for 1 day(Case 1) and for about 2 weeks (Case 2). Pimobendane was given to Case 2. Ejection fraction was 57% in Case 1 (2nd hospital day) and 33% (6th hospital day), 43% (7th hospital day)and 58% (16th hospital day)in Case 2. The recovery period of left ventricular abnormal wall motion and the medication period were longer in Case 2 showing diffuse hypokinesis than in Case 1 showing takotsubo-like cardiomyopathy.
