Summary
A spontaneous coronary artery dissection in a woman without cardiac risk factors was successfully treated with tissue plasminogen activator (t-PA). This rare case highlights the potential for positive outcomes with thrombolytic therapy in specific dissection scenarios.
Area of Science:
- Cardiology
- Vascular Medicine
Background:
- Spontaneous coronary artery dissection (SCAD) is a rare condition causing myocardial infarction, particularly in young women without traditional cardiac risk factors.
- Management strategies for SCAD remain debated, especially regarding the use of thrombolytic therapy during acute events.
Observation:
- A 42-year-old female presented with acute anterolateral myocardial infarction.
- Initial treatment involved intravenous tissue plasminogen activator (t-PA).
- Coronary angiography revealed extensive dissection of the left anterior descending artery and its diagonal branch.
Findings:
- The patient experienced an uneventful recovery and remained asymptomatic 16 months post-event.
- This case represents the fifth reported instance of SCAD treated with thrombolysis during the acute phase, leading to a favorable outcome.
Implications:
- Thrombolytic therapy may be a viable treatment option for select cases of spontaneous coronary artery dissection presenting as acute myocardial infarction.
- Further research is warranted to establish definitive guidelines for SCAD management, particularly concerning thrombolytic use.
