Abstract

Lesions in the medulla oblongata may be causally associated with cardiac wall motion abnormality (WMA). Although subarachnoid hemorrhage (SAH) patients occasionally develop WMA, the relationship between aneurysmal locations and the frequency of WMA has rarely been investigated. The objective of this study was to evaluate whether the frequency of WMA was higher after the rupture of vertebral artery (VA) aneurysms than that of non-VA aneurysms. We performed a retrospective chart analysis of 244 SAH patients who underwent transthoracic echocardiography and plasma catecholamine measurements. The frequencies of WMA and electrocardiographic (ECG) abnormalities were compared among patients classified by the location of aneurysms. Multivariate regression analysis was conducted to identify variables correlated with WMA. Furthermore, the relationship between plasma catecholamine levels and aneurysmal locations was evaluated. The frequency of WMA was significantly higher in patients with VA aneurysms than in those with non-VA aneurysms (45 vs. 22 %, p = 0.01). However, there was no significant difference in the frequency of ECG abnormalities. Multivariate regression analysis showed that VA aneurysms (OR, 3.317; 95 % CI, 1.129-9.745), poor...Continue Reading
