title: [Is early stent thrombosis an inflammatory disease? A study of 1306 implantations].
abstract: The authors tried to determine the clinical characteristics and predisposing factors of early stent thrombosis (EST) through the study of 15 patients who had had angiographically diagnosed stent thrombosis within 30 days of the implantation of the stent. The cases were compared to 29 control random patients collected between January 1, 2000 and August 31, 2001. Out of the 1306 patients who had been given coronary stents, 20 of them (1.5%) had an OO.. EST, representing 1.3 per patient. The patients, 12 males and 3 females, had a mean age of 62 + 10.3 years ranging between 46 and 77 years. EST occurred within 7.4 + 3.8 days (2 hours n 29 days) on average, in the left anterior descending branch (10 cases), in the right coronary artery (6cases) or in the left circumflex (3 cases) and finally in the postero-lateral branch (1 case). Stent recanalisation was performed within 3.4 + 2 hours (1-7 hours) on average. In spite of prompt revascularization, the problem progressed to MI in all cases and to subsequent death in 3 cases (20%). Procedure related variables of emergency PTCA, dissection, anatomical type B or C coronary lesions, related WBC count and C- reactive protein were significantly associated with EST while remained a rare event following PTCA. The incidence is low but the prognosis is still poor in spite of early intervention. Other studies are needed to confirm the probable inflammatory nature of this complication.
