Abstract
|
|
|
Objective: This study investigated the incidence and patterns of the acute coronary syndrome (ACS) after AAV diagnosis and searched for the predictors of ACS in a single-centre cohort of Korean patients diagnosed with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV).
Methods: A total of 262 patients with AAV were included in this study. ST-segment elevation myocardial infarction (STEMI), non-STEMI (NSTEMI), and unstable angina (UA) were defined as ACS in this study. Only ACS that occurred during or after AAV diagnosis was counted.
Results: The incidence of ACS in patients with AAV was 2.7% (7 patients), and the most common type of ACS was NSTEMI regardless of the affected site or the number of coronary arteries. Five patients with ACS were diagnosed with microscopic polyangiitis (MPA) and all of them had myeloperoxidase (MPO)-ANCA (or perinuclear [P]-ANCA), whereas the remaining two patients were diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA). Of the seven patients, 2 patients experienced ACS within the first year after AAV diagnosis, and 2 experienced ACS 5 years after AAV diagnosis. Among clinical variables, only the male sex was a predictor of ACS during the follow-up period in patients diagnosed with AAV.
Conclusion: The incidence of ACS was 2.7%, and the most common type of ACS was NSTEMI in Korean patients with AAV.
