What is the clinical evidence from this study?

Study design: Case Report. Population: Neurogenic Stunned Myocardium (n=2). Intervention: Acute neurological events.

What does this research mean for the field?

Neurogenic stunned myocardium mimics acute coronary syndrome through elevated troponin, electrocardiographic changes, and left ventricular dysfunction following acute neurological events, often necessitating cardiac catheterization to exclude coronary artery disease. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To increase clinical awareness regarding the presentation and diagnostic evaluation of neurogenic stunned myocardium following acute neurological injury.

Key result

Neurogenic stunned myocardium can mimic acute MI with ischemic ECG changes despite clear coronaries.

Why the study?

Neurogenic Stunned Myocardium is a diagnostically challenging condition following neurological events that mimics acute coronary syndrome and requires increased clinical awareness.

Implication

May warrant suspicion for neurogenic stunned myocardium to avoid unnecessary catheterization in acute neurological events; leaves open prospective validation of diagnostic criteria.

Key Points

To increase clinical awareness regarding the presentation and diagnostic evaluation of neurogenic stunned myocardium following acute neurological injury.
Evaluation of two male patients (N=2; aged 77 and 59 years) presenting to an emergency department with severe acute neurological deficits and cardiac abnormalities.
In Case 1, a 77-year-old male with subarachnoid and intraparenchymal hemorrhage presented with ST-elevation myocardial infarction patterns and ventricular fibrillation, but coronary angiography demonstrated no acute coronary occlusion.
In Case 2, a 59-year-old male with a 35x25 mm cerebral parenchymal hematoma displayed lateral ST depressions and elevated troponin (50.03 ng/L, reference 0–14 ng/L) without acute echocardiographic wall motion abnormalities, avoiding invasive coronary catheterization.

Population

Two older male patients presenting to the emergency department with neurogenic stunned myocardium mimicking acute coronary syndrome following acute neurological events.

Neurogenic stunned myocardium following acute neurological events can closely mimic acute myocardial infarction, necessitating a high index of suspicion and multidisciplinary approach to prevent inappropriate invasive cardiac procedures.

Limitations

Small sample size inherent to case reports
Lack of universal consensus on diagnostic criteria for neurogenic stunned myocardium

Cite This Study

Erdem et al. (2026) conducted a case report in Neurogenic Stunned Myocardium (n=2). Acute neurological events was evaluated. Neurogenic stunned myocardium following acute neurological events can mimic acute myocardial infarction with ischemic ECG changes and elevated troponin despite the absence of acute coronary occlusion.
