Prolongation of the atrioventricular conduction in fetuses exposed to maternal anti-Ro/SSA and anti-La/SSB antibodies did not predict progressive heart block. A prospective observational study on the effects of maternal antibodies on 165 fetuses.
We prospectively examined the prevalence and outcome of untreated fetal atrioventricular (AV) prolongation in the presence of maternal anti-Ro antibodies. ⋯ Fetal AV prolongation did not predict progressive heart block to birth. Our findings question the rationale of a management strategy that relies on the early identification and treatment of fetal AV prolongation to prevent CAVB.

We sought to analyze the composition of coronary thrombus in vivo in ST-segment elevation myocardial infarction (STEMI) patients. ⋯ In acute STEMI, platelet and fibrin contents of the occlusive thrombus are highly dependent on ischemia time, which may have a direct impact on the efficacy of drugs or devices used for coronary reperfusion.

Randomized Controlled Trial Multicenter Study Comparative StudyA randomized, double-blind, multicenter comparison study of triple antiplatelet therapy with dual antiplatelet therapy to reduce restenosis after drug-eluting stent implantation in long coronary lesions: results from the DECLARE-LONG II (Drug-Eluting Stenting Followed by Cilostazol Treatment Reduces Late Restenosis in Patients with Long Coronary Lesions) trial.
The purpose of this study was to determine whether cilostazol reduces intimal hyperplasia in patients undergoing long zotarolimus-eluting stent implantation (stent length: ≥ 30 mm) for native long coronary lesions (length: ≥ 25 mm). ⋯ Patients receiving triple antiplatelet therapy after long zotarolimus-eluting stent implantation had decreased extent of late luminal loss, percent intimal hyperplasia volume, and angiographic restenosis, resulting in a reduced risk of 12-month target lesion revascularization compared with patients receiving dual antiplatelet therapy. (Triple Versus Dual Antiplatelet Therapy after ABT578-Eluting Stent; NCT00589927).
