Key result
ECG, echo, and nuclear imaging diagnose Yamaguchi syndrome in a man with angina mimicking ACS.
Why the study?
Reporting this case serves to help physicians broaden their approach to patients presenting with symptoms mimicking acute coronary syndrome.
Case Report (n=1)
No
This case demonstrates that Yamaguchi syndrome (apical hypertrophic cardiomyopathy) can present in the Saudi population with symptoms mimicking acute coronary syndrome.
May warrant considering apical HCM in ACS mimics among Saudi patients; extends known geographic distribution beyond East Asian cohorts.
Apical hypertrophic cardiomyopathy, also called Yamaguchi syndrome, is a rare variant of hypertrophic cardiomyopathy. Yamaguchi syndrome is characterized by hypertrophy almost confined to the apical region of the left ventricle rather than the left ventricular septum. A case of 65-year-old Saudi man presented to the ER with angina, and the ECG, echocardiogram, and nuclear study confirmed the diagnosis with Yamaguchi. Reporting this case serves to help physicians broaden their vision in approaching patients with symptoms mimicking acute coronary syndrome.

Almehrij et al. (2024) conducted a case report in Yamaguchi syndrome (Apical hypertrophic cardiomyopathy) (n=1). A 65-year-old Saudi man presenting with angina mimicking acute coronary syndrome was successfully diagnosed with Yamaguchi syndrome using ECG, echocardiogram, and nuclear imaging.
