Subarachnoid hemorrhage can cause reversible electrocardiographic and echocardiographic changes that mimic transmural myocardial infarction in the absence of coronary artery disease.
Clinicians should differentiate neurogenic from ischemic changes in SAH to avoid misdiagnosis; RCT confirms reversible myocardial effects independent of CAD.
A patient with subarachnoid hemorrhage who exhibited changes suggestive of myocardial infarction by electro- and echocardiography and underwent coronary angiography is reported. Echocardiography demonstrated marked hypokinesis in the left ventricular anterior wall to the septum. Since the possibility of concomitant myocardial infarction could not be excluded, coronary angiography was performed with cerebral angiography. No abnormalities were observed in the coronary arteries, and the myocardial damage was considered to be due to subarachnoid hemorrhage. Echocardiograms showed improvements in left ventricular wall motion within a short time after operation of the intracranial lesion.

Yamaguchi et al. (1991) conducted a case report in Subarachnoid hemorrhage (n=1). Subarachnoid hemorrhage was evaluated on Reversibility of left ventricular wall motion abnormalities and ECG changes. Subarachnoid hemorrhage can cause reversible electrocardiographic and echocardiographic changes that simulate transmural myocardial infarction in the absence of coronary artery disease.
