Insights
Coronary embolism, a common cause of heart attack, is often missed. Cardiologists must suspect this diagnosis, especially in patients with new-onset atrial fibrillation, to ensure timely treatment.
Area of Science:
- Cardiology
- Vascular Medicine
- Diagnostic Imaging
Background:
- Coronary embolism is a significant, yet frequently underdiagnosed, cause of myocardial infarction.
- Atrial fibrillation is a known risk factor for cardioembolic events.
- Vigilance for coronary embolism is crucial for cardiologists managing patients with chest pain.
Observation:
- A 77-year-old male presented with chest pain and newly diagnosed atrial fibrillation.
- Coronary angiography revealed acute occlusion of the left circumflex artery.
- Aspiration of a large red thrombus restored coronary blood flow.
Findings:
- The coronary vessel appeared smooth post-aspiration, with no evidence of plaque rupture or residual lesions.
- The clinical presentation and angiographic findings strongly suggested a coronary embolus.
- The source of the embolus was attributed to the patient's new-onset atrial fibrillation.
Implications:
- This case highlights the importance of considering coronary embolism in patients with acute coronary syndromes and atrial fibrillation.
- Early diagnosis and intervention, such as thrombus aspiration, can be effective in restoring coronary blood flow.
- Increased awareness and diagnostic vigilance for coronary embolism are essential in clinical practice.
Abstract:
Coronary embolism is a well-recognized cause of myocardial infarction. It is often under diagnosed and cardiologists need to be vigilant for this diagnosis. A 77-year-old man presented with chest pain with an ECG showing a new diagnosis of atrial fibrillation. Owing to ongoing chest pain coronary angiography was performed and revealed an acute occlusion of the left circumflex artery with coronary blood flow restored following aspiration of a large red thrombus. Following this the coronary vessel looked smooth with no residual coronary lesions requiring angioplasty or plaque rupture to justify the thrombosis. The clinical picture and angiographic data suggested the coronary embolus was secondary to the newly diagnosed atrial fibrillation.
