Chronic primary coronary artery dissection can present uniquely in men over 40 with angina and severe coronary artery disease. The affected right coronary artery showed minimal atherosclerosis, warranting further investigation into this angiographic finding.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Radiology
Background:
- Coronary artery dissection is a rare condition affecting the heart's arteries.
- Primary spontaneous coronary artery dissection (SCAD) is distinct from dissection caused by trauma or atherosclerosis.
- Understanding variations in SCAD presentation is crucial for diagnosis and management.
Abstract:
Three patients had angiographic appearance of chronic primary coronary artery dissection with features that differed from other patients with this entity studied at autopsy; they were men, greater than or equal to 40 years of age, had angina pectoris and severe coronary artery disease. The right coronary artery, which was the artery involved with dissection, had only mild atherosclerosis. Further studies are needed to determine the natural history of this angiographic finding.
