Insights
Spontaneous coronary artery dissection (SCAD) is a rare cause of heart attack in young women. Prompt diagnosis and appropriate treatment, like bypass grafting in this case, improve outcomes.
Area of Science:
- Cardiology
- Vascular Medicine
Background:
- Spontaneous coronary artery dissection (SCAD) is an uncommon cause of acute coronary syndrome (ACS).
- SCAD should be considered in young women, particularly during the peripartum/postpartum periods, and in those without traditional cardiac risk factors.
- Associated conditions include drug abuse, collagen vascular disease, and chest trauma.
Observation:
- A young female patient with no traditional cardiovascular risk factors presented with ST-elevation myocardial infarction six hours post-thrombolysis.
- Coronary angiography revealed dissection of the left anterior descending artery and a branch.
- The patient underwent successful coronary artery bypass grafting.
Findings:
- Coronary artery bypass grafting led to complete healing of the left anterior descending dissection.
- Treatment strategies (medical, percutaneous, or surgical) can improve prognosis when tailored to clinical stability and angiographic findings.
- The potential for thrombolysis to worsen coronary dissection warrants further investigation.
Implications:
- Early recognition and targeted management are crucial for improving outcomes in SCAD patients.
- Coronary artery bypass grafting can be an effective treatment for SCAD, particularly in complex cases.
- This case highlights the importance of considering SCAD in young women presenting with ACS, even after thrombolysis.
Abstract:
Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome and sudden cardiac death. It should be suspected in every healthy young woman without cardiac risk factors, especially during the peripartum or postpartum periods. It is important to check for a history of drug abuse, collagen vascular disease or blunt trauma of the chest. Coronary angiography is essential for diagnosis and early management. We wonder whether thrombolysis might aggravate coronary dissection. All types of treatment (medical therapy, percutaneous intervention or surgery) improve the prognosis without affecting survival times if used appropriately according to the clinical stability and the angiographic features of the involved coronary arteries. Prompt recognition and targeted treatment improve outcomes. We report a case of SCAD in a young female free of traditional cardiovascular risk factors, who presented six hours after thrombolysis for ST elevation myocardial infarction. Coronary angiography showed a dissection of the left anterior descending and immediate branch. She had successful coronary artery bypass grafting, with complete healing of left anterior descending dissection.
