Insights
Spontaneous coronary artery dissection is a rare cause of heart attack and sudden death. This case describes a young man with widespread coronary dissection, treated medically after refusing surgery.
Area of Science:
- Cardiology
- Vascular Medicine
- Diagnostic Imaging
Background:
- Spontaneous coronary artery dissection (SCAD) is an uncommon cause of acute coronary syndrome.
- SCAD can lead to myocardial infarction and sudden cardiac death, particularly in younger individuals.
Observation:
- A 32-year-old male presented with exertional angina.
- Diagnostic workup included a positive exercise electrocardiogram test.
- Coronary angiography revealed dissection in all major coronary arteries, with complete occlusion of the left anterior descending artery.
Findings:
- The patient exhibited extensive spontaneous coronary artery dissection affecting multiple vessels.
- The left anterior descending artery occlusion was likely a consequence of the dissection process.
- Medical management was chosen over surgical intervention due to patient preference.
Implications:
- This case highlights the potential for widespread SCAD in young adults.
- It underscores the importance of considering SCAD in the differential diagnosis of angina and myocardial infarction.
- Conservative medical management can be an alternative to revascularization in selected SCAD cases.
Abstract:
Spontaneous coronary artery dissection is a rare cause of myocardial infarction and sudden cardiac death. A 32-year-old man presented with effort angina. He had a positive treadmill exercise electrocardiogram test, and coronary angiography showed that he had dissection of all major coronary vessels. The left anterior descending coronary artery was completely blocked, probably secondary to dissection and subsequent occlusion. He was advised to undergo coronary artery bypass surgery, to which he did not agree; instead, he was treated by medication and followed up.
