Left ventricular wall motion abnormalities in patients with subarachnoid hemorrhage: neurogenic stunned myocardium
The purpose of this study was to determine whether a relation exists between electrocardiographic (ECG) abnormalities and left ventricular wall motion in patients with subarachnoid hemorrhage. Although ECG changes simulating acute myocardial infarction are frequently seen in patients with subarachnoid hemorrhage, their relation to left ventricular wall motion has not been established. Twelve patients with subarachnoid hemorrhage were classified according to the presence of ST segment elevation in at least two consecutive leads on admission: seven patients with ST segment elevation (group I) and five patients without ST segment elevation (group II). No patients had a previous history of heart disease. Left ventricular regional wall motion was evaluated by the centerline method. The mean (+/- SEM) duration from onset of subarachnoid hemorrhage to left ventriculography was 9 +/- 3 h in group I and 10 +/- 1 h in group II. Coronary angiography was performed to rule out wall motion abnormalities due to coronary artery disease while the ST segment was still elevated. Two-dimensional echocardiography was used to evaluate wall motion thereafter. All patients in group I showed ST segment elevation in ECG leads V4 to V6. Wall motion of th...Continue Reading
