“…The diagnosis of apical HCM can be achieved by multiple different modalities. The key EKG finding is the “giant negative T waves” (greater than or equal to 10 mm) in the precordial leads and high QRS voltage in the absence of notable coronary artery disease [ 8 , 10 , 11 ]. These deep, inverted T waves are often mistaken for ACS [ 12 ].…”

Yamaguchi syndrome or apical hypertrophic cardiomyopathy (HCM) is a unique variant of HCM. It is characterized by localized hypertrophy involving the left ventricular apex rather than the left ventricular septum. This syndrome has been traditionally seen in the Asian population, particularly those of Japanese descent. We present an interesting case of Yamaguchi syndrome seen in a Hispanic male.A 48-year-old Hispanic male presented with epigastric tenderness and was admitted to the hospital for a non-ST-segment elevation myocardial infarction. His diagnostic catheterization revealed no significant coronary artery disease. However, his echocardiogram revealed apical hypertrophy and narrowing of the left ventricular cavity at the apex, consistent with Yamaguchi syndrome. Case reports such as ours serve to help clinicians broaden their differential diagnoses when approaching patients with acute coronary syndromelike symptoms to include diagnoses such as Yamaguchi syndrome.

“…Complementary imaging has become indispensable for the therapeutic planning of patients with AHCM [11]. In unusual presentations such as apical morphology, the determination of aspects such as myocardial fibrosis, valvar regurgitation, systolicdiastolic dysfunction, complex arrhythmias, myocardial ischemia, among others, shows the importance of diagnostic resources in order to allow longevity with quality of life as In the case described above [11][12][13][14][15][16].…”

Introduction: Yamaguchi Syndrome accounts for 15.0-25.0 % of all cases of hypertrophic cardiomyopathies in Japan. In addition, about 54.0 % of patients are symptomatic, including palpitations, dyspnoea, dizziness, syncope and chest pain. Objective: To present a special case of Apical Hypertrophic Cardiomyopathy (AHCM) in a female and Brazilian patient over eighty years old, as well as their recovery with pharmacological treatment. Highlight of Case: The present case report has its notorious importance due to its occurrence in patient without oriental descent; Longevity of the patient demonstrating the efficacy of pharmacological treatment; exhaustion of image evaluation methodologies for diagnosis and therapeutic conduction. Conclusion: The evolution of imaging diagnostic resources has made AHCM evaluation more elaborate, often providing information that helps therapeutical conduction, allowing an increase in survival with a significant improvement in quality of life.

“…Paraclinical diagnosis. Electrocardiography will reveal characteristically giant negative T waves, greater than 10 mm, and left ventricular hypertrophy, which can be confirmed using the Sokolov-Lyon criteria and calculating whether the sum of the S wave in V1 and the R wave in leads V5, V6 is greater than 35 mm [50]. These ECG changes should be presented as stand-alone and without the presence of an important underlying coronary artery disease or hypertension.…”

Electrocardiogram (ECG) still remains a very useful diagnostic method in modern cardiology. Its broad availability, noninvasiveness and good sensitivity explain why it plays a capital role in the very beginning of the process of diagnosis for every patient, with or without cardiac-related complaints. For the practitioner, good training in ECG interpretation is mandatory. Sometimes, the ECG trace reveals particular aspects that may cause confusion and complicate decision-making. In this article, we present several less common situations underlying the general context and ECG features. The syndromes studied have a high pathological significance and may range from acute emergencies that call for a rapid therapeutical response to chronic syndromes that require prolonged observation, monitoring and risk stratification.
