The coronary artery calcium score (CACS) has been shown to predict future heart disease (CHD) events. However, the extent which adding CACS traditional CHD risk factors improves classification of is unclear.To determine whether a prediction model based on risk.CACS was measured by computed tomography in 6814 participants from Multi-Ethnic Study Atherosclerosis (MESA), population-based cohort without known cardiovascular disease. Recruitment spanned July 2000 September 2002; follow-up...

<h3>Context</h3>Risk markers including coronary artery calcium, carotid intima–media thickness, ankle-brachial index, brachial flow–mediated dilation, high-sensitivity C-reactive protein (CRP), and family history of heart disease (CHD) have been reported to improve on the Framingham Risk Score (FRS) for prediction CHD, but there are no direct comparisons these risk in a single cohort.<h3>Objective</h3>We compared improvement incident CHD/cardiovascular (CVD) 6 within intermediate-risk...

<h3>Importance</h3> Clinical practice guidelines support home-based exercise for patients with peripheral artery disease (PAD), but no randomized trials have tested whether an intervention without periodic medical center visits improves walking performance. <h3>Objective</h3> To determine a consisting of wearable activity monitor and telephone coaching ability over 9 months in PAD. <h3>Design, Setting, Participants</h3> Randomized clinical trial conducted at 3 US centers. Patients PAD were...

Background: The most appropriate score for evaluating the pretest probability of obstructive coronary artery disease (CAD) is unknown. We sought to compare Diamond-Forrester (DF) with 2 CAD consortium scores recently recommended by European Society Cardiology. Methods: included 2274 consecutive patients (age, 56±13 years; 57% male) without prior referred computed tomographic angiography. Computed angiography findings were used determine presence or absence (≥50% stenosis). compared DF...

Abstract Whether initiation of statins could increase survival free dementia and disability in adults aged ≥75 years is unknown. PREVENTABLE, a double‐blind, placebo‐controlled randomized pragmatic clinical trial, will compare high‐intensity statin therapy (atorvastatin 40 mg) with placebo 20,000 community‐dwelling without cardiovascular disease, disability, or at baseline. Exclusion criteria include use the prior year for &gt;5 inability to take statin. Potential participants are identified...

Background Few adults have ideal cardiovascular health ( CVH ). We studied associations of an overall score with subclinical disease and events. assessed whether varied by race/ethnicity. Methods Results Among 5961 participants in the Multi‐Ethnic Study Atherosclerosis, components were measured at baseline, 2000‐2002: systolic blood pressure, total cholesterol, fasting glucose, smoking, physical activity, diet, body mass index. Levels classified as (2 points), intermediate (1 point), poor (0...

In the general population, majority of cardiovascular events occur in people at low to moderate end population risk distribution. The 2013 American College Cardiology/American Heart Association guideline on treatment blood cholesterol recommends consideration statin therapy for adults with an estimated 10-year atherosclerotic disease (ASCVD) ≥7.5% based traditional factors. Whether use nontraditional markers can improve assessment those below this threshold is unclear.Using data from...

<h3>Importance</h3> Trans-fatty acids (TFAs) have deleterious cardiovascular effects. Restrictions on their use were initiated in 11 New York State (NYS) counties between 2007 and 2011. The US Food Drug Administration plans a nationwide restriction 2018. Public health implications of TFA restrictions are not well understood. <h3>Objective</h3> To determine whether NYS associated with fewer hospital admissions for myocardial infarction (MI) stroke compared without restrictions. <h3>Design,...

<h3>Importance</h3> Benefits of granulocyte-macrophage colony-stimulating factor (GM-CSF) for improving walking ability in people with lower extremity peripheral artery disease (PAD) are unclear. Walking exercise may augment the effects GM-CSF PAD, since exercise-induced ischemia enhances progenitor cell release and promote homing to ischemic calf muscle. <h3>Objectives</h3> To determine whether combined supervised treadmill improves 6-minute walk distance, compared alone alone; more than...

<h3>Importance</h3> Research shows that resveratrol, a sirtuin activator in red wine, improves exercise endurance and skeletal-muscle oxidative metabolism animals may enhance vascular function humans. Resveratrol supplement sales exceed $30 million annually the United States, but few data are available regarding its efficacy <h3>Objective</h3> To determine whether 125 mg/d or 500 mg/d, 6-minute walk performance patients with peripheral artery disease (PAD). <h3>Design, Setting,...
