Insights
Chest pain can stem from anxiety or serious issues like myocardial bridging. This case shows why doctors must consider less common causes, even with psychiatric conditions, for accurate diagnosis.
Area of Science:
- Cardiology
- Internal Medicine
- Psychiatry
Background:
- Chest pain is a common reason for emergency visits, with coronary artery disease being the most frequent cause.
- Other etiologies, including congenital anomalies like myocardial bridging, should be considered in cases of myocardial ischemia.
Observation:
- A 45-year-old male with a history of anxiety and depression presented with worsening chest pain, fatigue, and dyspnea.
- Initial evaluations were unremarkable, but stress testing revealed ischemia, and echocardiography showed hypokinesis.
- Coronary angiography identified a myocardial bridge in the left anterior descending artery without obstructive lesions.
Findings:
- Myocardial bridging, a congenital anomaly, can cause angina-like symptoms and non-obstructive ischemia.
- Diagnostic delays can occur in patients with chest pain and psychiatric comorbidities.
Implications:
- This case underscores the importance of a comprehensive evaluation for chest pain, considering less common causes like myocardial bridging.
- A holistic clinical approach is crucial for timely diagnosis and management, especially in patients with overlapping psychiatric symptoms.
- Physicians should be aware of myocardial bridging as a potential cause of non-obstructive ischemia.
Abstract:
Chest pain is a frequent cause of emergency medical visits and can result from either benign or life-threatening conditions. While atherosclerotic coronary artery disease is the most common etiology, other causes of myocardial ischemia, such as congenital anomalies like myocardial bridging, should also be considered. This case report is about a 45-year-old male with a psychiatric history of major depressive disorder and generalized anxiety, under treatment with fluvoxamine. He had multiple visits over six years to primary care for chest pain episodes consistently attributed to anxiety, with normal ECG findings. In 2024, he presented with worsening chest pain at rest, fatigue, and exertional dyspnea. While initial assessment in the emergency department was unremarkable, further evaluation showed ischemia on stress testing and hypokinesis on echocardiogram. Coronary angiography revealed a myocardial bridge in the left anterior descending artery with no obstructive lesions. He was discharged on beta-blockers and referred for outpatient cardiology follow-up. This case highlights the diagnostic challenge of chest pain in the presence of psychiatric comorbidities. It underlines the importance of comprehensive evaluation and consideration of less common causes of ischemia, such as myocardial bridging, especially when symptoms persist despite reassuring initial tests. Myocardial bridging, although frequently asymptomatic, may present with angina-like symptoms and should be part of the differential diagnosis for non-obstructive ischemia. A careful and holistic clinical approach is essential to avoid diagnostic delays, particularly in patients with overlapping psychiatric symptoms. Furthermore, this case aims to raise awareness among physicians about less common causes of chest pain.
