Randomized Controlled Trial Comparative StudyThe impact of patient and lesion complexity on clinical and angiographic outcomes after revascularization with zotarolimus- and everolimus-eluting stents: a substudy of the RESOLUTE All Comers Trial (a randomized comparison of a zotarolimus-eluting stent with an everolimus-eluting stent for percutaneous coronary intervention).
The aim of this study was to investigate the impact of patient and lesion complexity on outcomes with newer-generation zotarolimus-eluting stents (ZES) and everolimus-eluting stents (EES). ⋯ In this all-comers randomized trial, major adverse cardiovascular events were more frequent among complex than simple patients. The newer-generation ZES and EES proved to be safe and effective, regardless of complexity, with similar clinical and angiographic outcomes for both stent types through 1 year. (RESOLUTE-III All Comers Trial: A Randomized Comparison of a Zotarolimus-Eluting Stent With an Everolimus-Eluting Stent for Percutaneous Coronary Intervention; NCT00617084).

The early repolarization pattern in the general population: clinical correlates and heritability.
This study sought to describe the clinical correlates and heritability of the early repolarization pattern (ERP) in 2 large, population-based cohorts. ⋯ ERP has strong association with clinical factors and has evidence for a heritable basis in the general population. Further assessment of the genetic determinants of ERP is warranted.

ReviewHeart failure and chronic obstructive pulmonary disease the quandary of Beta-blockers and Beta-agonists.
The combination of heart failure and chronic obstructive pulmonary disease presents many therapeutic challenges. The cornerstones of therapy are beta-blockers and beta-agonists, respectively. Their pharmacological effects are diametrically opposed, and each is purported to adversely affect the alternative condition. ⋯ Beta-agonists are associated with incident heart failure in patients with pulmonary disease and with increased mortality and hospitalization in those with existing heart failure. These purported adverse effects require further investigation. In the meantime, clinicians should consider carefully the etiology of dyspnea and obtain objective evidence of airflow obstruction before prescribing beta-agonists to patients with heart failure.

Association of annular calcification and aortic valve sclerosis with brain findings on magnetic resonance imaging in community dwelling older adults: the cardiovascular health study.
The objective of this study was to investigate the associations of mitral annular calcification, aortic annular calcification, and aortic valve sclerosis with covert magnetic resonance imaging (MRI)-defined brain infarcts. ⋯ Left-sided cardiac annular and valvular calcifications are associated with covert MRI-defined brain infarcts. Further study is warranted to identify mechanisms and determine whether intervening in the progression of annular and valvular calcification could reduce the incidence of covert brain infarcts as well as the associated risk for cognitive impairment and future stroke.
