Insights
Multiple coronary artery thrombosis is a rare but serious complication of ST segment elevation myocardial infarction (STEMI). Prompt treatment with thrombus aspiration and antiplatelet therapy can be effective in managing these critical cases.
Area of Science:
- Cardiology
- Interventional Cardiology
- Emergency Medicine
Background:
- ST segment elevation myocardial infarction (STEMI) typically involves single coronary artery occlusion.
- Simultaneous multiple coronary artery thrombosis is an uncommon and often fatal presentation of STEMI.
Purpose of the Study:
- To report a rare case of STEMI with multiple distal coronary artery occlusions.
- To highlight the successful management of this critical condition.
Main Methods:
- Emergency coronary angiography was performed.
- Thrombus aspiration was utilized for the distal left anterior descending artery (dLAD).
- Systemic glycoprotein IIb/IIIa inhibitor therapy was administered.
Main Results:
- The patient presented with multiple ST segment elevations on electrocardiography.
- Total occlusions were identified in the dLAD, second, and third obtuse marginal arteries.
- Successful treatment was achieved with thrombus aspiration and glycoprotein IIb/IIIa inhibition.
Conclusions:
- Multiple coronary thromboses in STEMI are unusual and carry a high fatality rate.
- Assertive thrombus aspiration and antiplatelet therapy demonstrate efficacy in STEMI patients with multiple distal coronary occlusions.
Abstract:
Simultaneous multiple coronary artery thrombosis is a rare finding in ST segment elevation myocardial infarction (STEMI). We report a case of myocardial infarction with multiple ST segment elevation on the electrocardiography and total occlusions of the distal left anterior descending artery (dLAD), as well as of the second and third obtuse marginal artery on emergency coronary angiography. Thrombus aspiration was performed at dLAD and systemic glycoprotein IIb/IIIa inhibitor was used successfully. In patients with STEMI, multiple coronary thromboses are unusual and associated with patient fatality. However, assertive thrombus aspiration and antiplatelet therapy could be effective in STEMI patients with multiple distal coronary artery occlusions.
