SCA como Manifestacion Clínica de la Reestenosis Intrastent

In-stent re-stenosis(ISR) has been associated with a high incidence of reintervention, but in addition some reports indicate that acute coronary syndromes(ACS) are a frequent clinical presentation. In this study of 210 patients with ISR we found that ACS was thepresenting event in 31% of patients while a stable clinical event occurred in 69%. In the ACS group 21 patients (31%) had an STEMI, 20 (29%) an NSTE-MI and 27 (40%) patients presented with unstableangina. Comparing ACS vs SE groups, clinical cha-acteristics were similar, except for diabetes which was more frequent in ACS (30% vs 22%, p=0,02). Thirty day mortality was 2,9% vs 2,1% (p=ns) and long term mortality was 12,2% vs 6,4%, respecti-vely (p=0.18). In multivariate analysis, there wereno independent predictors of an SCA presentation. In conclusion, ACS is a frequent clinical presentation of ISR and it is not always a benign condition.
