Antithrombotic treatment strategy for patients with coronary artery ectasia and acute myocardial infarction: A case report.

BACKGROUND

There is no consensus on the antithrombotic treatment strategy for patients with coronary artery ectasia (CAE).

CASE SUMMARY: This case reports the dynamic observation of a patient for 48 mo after a diagnosis of CAE with acute myocardial infarction (AMI). The first antithrombotic agents used were aspirin (100 mg/d) and clopidogrel (75 mg/d). During the sixth month of observation, a second AMI occurred involving the same culprit vessel; therefore, antithrombotic agents were changed to aspirin (100 mg/d) and ticagrelor (90 mg twice per day). Twelve months after the second AMI, an attempt to reduce the dosage ticagrelor failed; therefore the original dose was continued. The CAE was relatively stable during the following 4 years.

CONCLUSION

This case indicates that a combination of aspirin and ticagrelor may be more effective for CAE patients with AMI than aspirin and clopidogrel.
