Transradial versus transfemoral rotablation for heavily calcified coronary lesions in contemporary drug-eluting stent era.

Background: Although radial access for drug-eluting stent (DES) combined with rotational atherectomy (RA) in patients with calcified coronary lesions may be associated with a lower risk of major bleeding complications and obtain favorable clinical results compared with femoral access, the long-term outcome data of this approach were limited in contemporary DES era.

Methods & Results: This retrospective study sought to compare in-hospital and long-term outcomes for patients undergoing RA via the transradial (TR) and transfemoral (TF) route in 126 consecutive patients (59 radial, 67 femoral) from 2009 to 2014. TR RA procedures were performed in 44/62 (71%) by the three TR operators, compared with 15/64 (23%) by the four TF operators in the present study.

Effects of moderate alcohol consumption on inflammatory biomarkers.

Objectives: Although light to moderate alcohol consumption has been associated with lower all-cause and cardiovascular (CV) mortality, the underlying mechanisms are only partly understood. Evidence has emerged in recent years that atherosclerosis is an inflammatory disease. We hypothesize that beneficial effects of moderate alcohol consumption on CV mortality may be linked to antiinflammatory effects.

Hemodynamic significance of heart rate in neurally mediated syncope.

Background: Vasovagal and vasodepressor syncope are used interchangeably in the literature to describe the common faint syndrome, now collectively named neurally mediated syncope. The significance of heart rate (HR) in these reflex-induced reactions remains unclear.

Hypothesis: The study was undertaken to investigate the hemodynamic significance of HR in tilt-induced neurally mediated syncope.
