Mid-ventricular obstructive hypertrophic cardiomyopathy with apical aneurysm is a rare condition that should be considered in the differential diagnosis of patients presenting with ST-segment elevation mimicking acute STEMI.
Nonischemic ST-segment elevation may be confused as acute ST-elevation myocardial infarction (STEMI), especially in patients with atypical presenting symptoms. Among the possible differential diagnosis, hypertrophic cardiomyopathy (HCM) should be considered. Mid-ventricular obstructive hypertrophic cardiomyopathy (MVOHCM) is a rare type of cardiomyopathy, accounting for approximately 5% of all HCM cases. ST-segment elevation on electrocardiogram (ECG) in patients with MVOHCM is a rare clinical presentation. We present a case of MVOHCM and apical aneurysm mimicking acute STEMI.
