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.

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...

High-sensitive cardiac troponin T and its relations to cardiovascular risk factors, morbidity, and mortality in elderly men
In this study, we investigated the associations of cardiac troponin T (cTnT) to cardiovascular (CV) disease and outcome in elderly men.Methods: Cardiac troponin T was measured using a high-sensitive assay in 940 men aged 71 years participating in the Uppsala Longitudinal Study of Adult Men. We assessed both the cross-sectional associations of cTnT to CV risk factors and morbidities including cancer and the longitudinal associations to outcomes over 10 years of follow-up.Results: Cardiac troponin T levels were measurable in 872 subjects (92.8%). In the cross-sectional analyses, cTnT was associated to CV risk factors (diabet...

Burden, timing, and relationship of cardiovascular hospitalization to mortality among Medicare beneficiaries with newly diagnosed atrial fibrillation
Conclusions: Cardiovascular hospitalization is common in the first year after AF diagnosis. Atrial fibrillation, heart failure, myocardial infarction, and stroke/transient ischemic attack account for half of primary hospitalization diagnosis. Cardiovascular hospitalization is independently associated with mortality, irrespective of time from diagnosis to first hospitalization, and represents a critical inflection point in survival trajectory. These findings highlight the importance of CV hospitalization as a marker of disease progression and poor outcomes. Efforts to clarify the determinants of hospitalization could inform...

African American race but not genome-wide ancestry is negatively associated with atrial fibrillation among postmenopausal women in the Women's Health Initiative
Conclusion: African American race is significantly and inversely correlated with AF in postmenopausal women. The etiology of this association remains unclear and may be related to unidentified environmental differences. Larger studies are necessary to identify genetic determinants of AF in African Americans.

Evaluation of the dual peroxisome proliferator–activated receptor α/γ agonist aleglitazar to reduce cardiovascular events in patients with acute coronary syndrome and type 2 diabetes mellitus: Rationale and design of the AleCardio trial
Conclusions: AleCardio will establish whether the PPAR-α/γ agonist aleglitazar improves cardiovascular outcomes in patients with diabetes and high-risk coronary disease.

Effect of ticagrelor on the outcomes of patients with prior coronary artery bypass graft surgery: Insights from the PLATelet inhibition and patient outcomes (PLATO) trial
Conclusions: Prior-CABG patients presenting with acute coronary syndrome are a high-risk cohort for death and recurrent cardiovascular events but have a lower risk for major bleeding. Similar to the results in no-prior-CABG patients, ticagrelor was associated with a reduction in ischemic events without an increase in major bleeding.

Apixaban versus warfarin in patients with atrial fibrillation according to prior warfarin use: Results from the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation trial
Background: Patients with atrial fibrillation who are vitamin K antagonist (VKA)-naive may have a higher risk of thrombosis and/or bleeding than VKA-experienced patients.Methods and results: Using data from ARISTOTLE, we assessed baseline characteristics and the treatment effect of apixaban versus warfarin in the VKA-naive and VKA-experienced cohorts. We compared rates of study drug discontinuation and time-in-therapeutic range. Overall, 7,800 (43%) were VKA naive, and 10,401 were VKA experienced. At baseline, both groups were similar with respect to age and congestive heart failure, hypertension, age, diabetes, stroke sco...

Effects of nonpersistence with medication on outcomes in high-risk patients with cardiovascular disease
Background: The impact of nonpersistence on events and of events on persistence is unclear. We studied the effects of nonpersistence on outcomes and events on nonadherence in a randomized placebo controlled trial in 40 countries on 25,620 patients.Methods: In the ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial (ONTARGET), persistent patients (n = 20,991) were compared with individuals who had permanently stopped study medications (n = 4,629).Results: Older age, female gender, less physical activity, less education, and history of stroke/transient ischemic attack, depression, and diabetes we...
