Insights
Chest pain in hypertrophic cardiomyopathy (HCM) may indicate myocardial bridging, not just acute coronary syndrome (ACS). This condition, where an artery segment is covered by muscle, is more common in HCM patients and can cause ischemia.
Area of Science:
- Cardiology
- Cardiovascular Medicine
- Medical Case Reports
Background:
- Apical hypertrophic cardiomyopathy (HCM) can present with chest pain, often raising concern for acute coronary syndrome (ACS).
- Obstructive coronary artery disease is a common cause of chest pain, but other etiologies should be considered when it is excluded.
Abstract:
Chest pain with apical hypertrophic cardiomyopathy (HCM) warrants concern for acute coronary syndrome (ACS). When obstructive coronary disease is excluded, myocardial bridging should remain an important consideration. We report a 60-year-old female with apical HCM and multiple prior evaluations for a mix of typical and atypical chest pain who presented with worsening dyspnea on exertion and stable intermittent chest pain. Coronary angiography revealed a myocardial bridge involving the posterior descending artery (PDA). Given the increased prevalence of myocardial bridging in the HCM population and its association with increased risk of myocardial ischemia, workup for angina-like symptoms should incorporate evaluation for a myocardial bridge.

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
