Rationale and design of The Intracoronary Stenting and Antithrombotic Regimen—Testing of a six-week versus a six-month clopidogrel treatment Regimen In Patients with concomitant aspirin and oraL anticoagulant therapy following drug-Eluting stenting (ISAR-TRIPLE) study
Background: An increasing number of patients undergoing coronary stenting need lifelong anticoagulation and therefore require a triple therapy typically consisting of aspirin, clopidogrel, and a vitamin K antagonist. Triple therapy confers an elevated bleeding risk as compared with dual therapy; however, omission of either antiplatelet or anticoagulation therapy might increase the risk of stent thrombosis or thrombembolic events. Although guidelines recommend a duration of dual antiplatelet therapy of 6 to 12months after drug-eluting stent (DES) implantation, the optimal duration of dual antiplatelet therapy in patients re...

Scar tissue–guided left ventricular lead placement for cardiac resynchronization therapy in patients with ischemic cardiomyopathy: An acute pressure-volume loop study
Background: Response to cardiac resynchronization therapy (CRT) is hampered by the extent and location of left ventricular (LV) scar tissue. It is commonly advised to avoid scar tissue while placing the LV lead. However, whether individual patients benefit from this strategy remains unclear.Methods: Thirty-two CRT candidates with ischemic cardiomyopathy were enrolled from 2 successive clinical trials (TBS and E-pot study). Magnetic resonance imaging with late contrast enhancement was performed to assess location, degree and transmurality of LV scar tissue. Patients underwent invasive pressure-volume loop measurements to as...

Growth differentiation factor 15 and cardiovascular events in patients with stable ischemic heart disease (The Heart and Soul Study)
Background: Growth differentiation factor 15 (GDF-15) is a relatively new biomarker that predicts mortality in patients with chronic stable angina or acute coronary syndrome. However, the association of GDF-15 with cardiovascular (CV) events and the mechanisms of this association are not well understood.Methods: We measured plasma GDF-15 and cardiac disease severity in 984 patients with stable ischemic heart disease who were recruited for the Heart and Soul Study between September 2000 and December 2002. Subsequent CV events (myocardial infarction, stroke, and CV death), hospitalization for heart failure, and all-cause mor...

Association of all-cause and cardiovascular mortality with prehypertension: A meta-analysis
Background: Studies of prehypertension and mortality are controversial after adjusting for other cardiovascular risk factors. This meta-analysis sought to evaluate the association of prehypertension with all-cause and cardiovascular disease (CVD) mortality.Methods: The PubMed, EMBASE, Cochrane Library databases, and conference proceedings were searched for studies with data on prehypertension and mortality. The relative risks (RRs) of all-cause, CVD, coronary heart disease (CHD), and stroke mortality were calculated and presented with 95% CIs. Subgroup analyses were conducted according to blood pressure, age, gender, ethni...

Rationale, design, and organization of a randomized, controlled Trial Evaluating Cardiovascular Outcomes with Sitagliptin (TECOS) in patients with type 2 diabetes and established cardiovascular disease
Sitagliptin, an oral dipeptidyl peptidase-4 inhibitor, lowers blood glucose when administered as monotherapy or in combination with other antihyperglycemic agents. TECOS will evaluate the effects of adding sitagliptin to usual diabetes care on cardiovascular outcomes and clinical safety. TECOS is a pragmatic, academically run, multinational, randomized, double-blind, placebo-controlled, event-driven trial recruiting approximately 14,000 patients in 38 countries who have type 2 diabetes (T2DM), are at least 50 years old, have cardiovascular disease, and have an hemoglobin A1c value between 6.5% and 8.0%. Eligible participan...

Radial versus femoral approach comparison in percutaneous coronary intervention with intraaortic balloon pump support: The RADIAL PUMP UP Registry
Background: The role of intraaortic balloon pump (IABP) during percutaneous coronary intervention (PCI) in high-risk acute patients remains debated. Device-related complications and the more complex patient management could explain such lack of clinical benefit. We aimed to assess the impact of transradial versus transfemoral access for PCI requiring IABP support on vascular complications and clinical outcome.Methods: We retrospectively analyzed 321 consecutive patients receiving IABP support during transfemoral (n = 209) or transradial (n = 112) PCI. Thirty-day net adverse clinical events (NACEs) (composite of postprocedu...

Design of the liraglutide effect and action in diabetes: Evaluation of cardiovascular outcome results (LEADER) trial
Conclusions: LEADER commenced in September 2010, and enrollment concluded in April 2012. There were 9,340 patients enrolled at 410 sites in 32 countries. The mean age of patients was 64.3 ± 7.2 years, 64.3% were men, and mean body mass index was 32.5 ± 6.3 kg/m2. There were 7,592 (81.3%) patients with prior CVD and 1,748 (18.7%) who were high risk but without prior CVD. It is expected that LEADER will provide conclusive data regarding the cardiovascular safety of liraglutide relative to the current standard of usual care for a global population of patients with T2DM.

Dual antiplatelet therapy versus oral anticoagulation plus dual antiplatelet therapy in patients with atrial fibrillation and low-to-moderate thromboembolic risk undergoing coronary stenting: Design of the MUSICA-2 randomized trial
Conclusions: The MUSICA-2 will attempt to determine the most effective and safe treatment in patients with nonvalvular AF and CHADS2 score ≤2 after PCI-S. Restricting TT for AF patients at high risk for stroke may reduce the incidence of bleeding without increasing the risk of thromboembolic complications.

Response to letter by Messeri et al
We thank Dr Messeri and colleagues for their interest in our network meta-analysis on the risk of stroke in patients treated with on-pump coronary artery bypass graft (CABG), off-pump CABG, and percutaneous coronary intervention (PCI), which builds upon a prior comprehensive pairwise analysis on the same topic. The crude event rates by simple pooling of data are 148/10,957 (1.4%) for 79 studies of on-pump CABG, 72/7,119 (1.0%) for 70 studies of off-pump CABG, and 15/4,653 (0.3%) for 17 studies of PCI. From a Bayesian binomial random-effect model, the absolute risk estimate for stroke was 1.4% in patients treated with on-pu...

Documentation of study medication dispensing in a prospective large randomized clinical trial: Experiences from the ARISTOTLE Trial
Conclusions: Rates of medication dispensing error were low and balanced between treatment groups. The initially reported dispensing error rate was the result of data recording and data management errors and not true medication dispensing errors. These analyses confirm the previously reported results of ARISTOTLE.
