Multiple spontaneous coronary artery dissections in a middle aged woman: support for an underlying eosinophilic
Insights
A patient experienced myocardial infarction and received tissue plasminogen activator, leading to coronary artery dissections. This rare case highlights the risks associated with thrombolytic therapy in spontaneous coronary artery dissection.
Area of Science:
- Cardiology
- Vascular Biology
- Pathology
Background:
- Spontaneous coronary artery dissection (SCAD) is a rare cause of myocardial infarction, particularly in women.
- Tissue plasminogen activator (tPA) is a thrombolytic agent used to treat acute myocardial infarction.
Observation:
- A 43-year-old female presented with acute antero-apical myocardial infarction.
- She received tissue plasminogen activator (tPA) for treatment.
- Cardiac catheterization revealed three focal dissections in the left anterior descending and circumflex arteries.
Findings:
- The patient underwent emergency coronary artery bypass grafting due to infarct extension.
- She experienced an unexpected fatal outcome post-procedure.
- This represents the fourth reported case of multiple spontaneous coronary artery dissections and the second involving tPA administration.
Implications:
- The case underscores the potential complications of thrombolytic therapy in the context of SCAD.
- Histologic findings are crucial for understanding the pathogenesis of SCAD.
- Further research is needed to establish optimal management strategies for SCAD patients, especially those receiving thrombolytics.
Abstract:
A 43-year-old female received tissue plasminogen activator for an acute antero-apical myocardial infarction. Cardiac catheterization demonstrated three focal dissections involving the left anterior descending and circumflex arteries. She expired unexpectantly after undergoing emergency coronary artery bypass grafting for therapy of an extension of her infarct. To our knowledge, this is the fourth report of multiple spontaneous coronary artery dissections and the second in which tissue plasminogen activator was administered. The histologic findings and their implications are reviewed.
