BACKGROUND Many myocardial infarctions and strokes occur in individuals with low-density lipoprotein cholesterol levels below recommended treatment thresholds. High sensitivity C-reactive protein (hs-CRP) testing has been advocated to identify low- and intermediate-risk individuals who may benefit from statin therapy. METHODS AND RESULTS A decision(More)
BACKGROUND Change in coronary artery calcification is a surrogate marker of subclinical coronary artery disease (CAD). In the only large prospective study, CAD risk factors predicted progression of coronary artery calcium (CAC). METHODS We measured CAC at enrollment and after 24 months in a community-based sample of 869 healthy adults aged 60 to 72 years(More)
BACKGROUND Lipoprotein-associated phospholipase A₂ (Lp-PLA₂) is a predictor of cardiovascular events that has been shown to vary with race. The objective of this study was to examine factors associated with this racial variation. METHODS We measured Lp-PLA₂ mass and activity in 714 healthy older adults with no clinical coronary heart disease and not(More)
BACKGROUND Although chronic renal insufficiency (CRI) is associated with increased cardiac and noncardiac mortality, there is limited data on the relationship between CRI and survival in patients with implantable cardioverter-defibrillators (ICDs), particularly across a wide range of renal function. METHODS We studied 507 consecutive patients receiving(More)
AIMS Given the selectivity of clinical trial patients and meager representation of elderly in the major implantable cardioverter defibrillator (ICD) randomized trials (<25%), whether such data apply to elderly patients overall is unclear. The purpose of our study is to understand the influence of age on mortality after ICD implantation. METHODS AND(More)
BACKGROUND & AIMS The cost effectiveness of alternative approaches to the diagnosis of small-bowel Crohn's disease is unknown. This study evaluates whether computed tomographic enterography (CTE) is a cost-effective alternative to small-bowel follow-through (SBFT) and whether capsule endoscopy is a cost-effective third test in patients in whom a high(More)
We sought to assess survival, predictors of adverse outcomes, and complication rates in a more recent series of adults undergoing percutaneous aortic balloon valvuloplasty (PABV) for symptomatic calcific aortic stenosis. While aortic valve replacement is the treatment of choice for adults with symptomatic calcific aortic stenosis, PABV has been used in(More)
BACKGROUND Readmission within 30 days after hospitalization for heart failure (HF) is a major public health problem. OBJECTIVE To examine whether timing and type of post-discharge follow-up impacts risk of 30-day readmission in adults hospitalized for HF. DESIGN Nested matched case-control study (January 1, 2006-June 30, 2013). SETTING A large,(More)
An Olympus ultrathin fiberscope, 1.8 mm outer diameter, was inserted intraluminally into 11 stenoses of the left anterior descending and circumflex coronary arteries in 8 patients at coronary bypass surgery. Intraluminal views were obtained by coupling the angioscope to a color video camera and videotape recorder, and compared with preoperative coronary(More)
Aldosterone receptor antagonists have been shown in randomized trials to reduce morbidity and mortality in adults with symptomatic systolic heart failure. We studied the effectiveness and safety of spironolactone in adults with newly diagnosed systolic heart failure in clinical practice. We identified all adults with newly diagnosed heart failure, left(More)
