A case of Takayasu arteritis with repeated coronary artery restenosis after drug-eluting stent implantation successfully treated with a combination of steroids.

A 52-year-old woman with Takayasu arteritis developed acute coronary syndrome and received percutaneous coronary intervention (PCI). The patient experienced restenosis three times even with drug-eluting stent (DES) implantation. We started steroid administration after the fourth PCI to reduce inflammation due to autoimmunity.

Elevation of plasma granzyme B levels after acute myocardial infarction.

Methods And Results: Peripheral blood samples were obtained from 33 patients with a first-onset AMI treated by percutaneous coronary intervention (mean age: 61.
