Neurogenic Stunned Myocardium (NSM) refers to transient cardiac abnormalities, including electrocardiographic changes, that occur following acute neurological events such as stroke or subarachnoid hemorrhage. These presentations can closely mimic acute myocardial infarction, often with normal coronary angiography findings. We report the case of a 51-year-old male who presented with a subarachnoid hemorrhage secondary to methamphetamine intoxication. The patient exhibited ECG changes suggestive of myocardial ischemia, but no evidence of obstructive coronary artery disease was found. His condition deteriorated rapidly. This case highlights the rare and under-recognized phenomenon of NSM, emphasizing the importance of distinguishing it from primary cardiac pathology. In settings where immediate coronary intervention is unavailable or when the diagnosis of myocardial infarction is uncertain, a comprehensive systemic evaluation including detailed history-taking, ECG, toxicology screening, and both coronary and neuroimaging is essential to identify alternative causes and guide appropriate management.
