IMPORTANCE Myocardial infarction (MI) is an established risk factor for atrial fibrillation (AF). However, the extent to which AF is a risk factor for MI has not been investigated. OBJECTIVE To examine the risk of incident MI associated with AF. DESIGN, SETTING, AND PARTICIPANTS A prospective cohort of 23,928 participants residing in the continental(More)
BACKGROUND In the general population, the majority of cardiovascular events occur in people at the low to moderate end of population risk distribution. The 2013 American College of Cardiology/American Heart Association guideline on the treatment of blood cholesterol recommends consideration of statin therapy for adults with an estimated 10-year(More)
Calcified coronary arteries are associated with the development of cardiovascular disease and stroke. It is currently unknown whether coronary artery calcium (CAC) is associated with an increased risk for atrial fibrillation (AF). The aim of this study was to address this question in 6,641 participants (mean age 62 ± 10 years, 53% women, 62% nonwhites) from(More)
Widening of the electrocardiographic (ECG) spatial QRS-T angle has been predictive of cardiovascular disease (CVD) events in the general population. However, its prognostic significance in human immunodeficiency virus (HIV)-infected patients remains unknown. The spatial QRS-T angle was derived from the baseline resting 12-lead electrocardiogram of 4,453(More)
IMPORTANCE Bradycardia has been associated with lower cardiovascular disease (CVD) risk in selected populations. There is a paucity of information available about heart rate (HR) less than 50 beats per minute (bpm) among middle-aged or older adults. OBJECTIVE To determine whether asymptomatic bradycardia was associated with a lower cardiovascular risk(More)
BACKGROUND Temporary-permanent pacemakers [TPPM] are externally placed permanent generators attached to active fixation transvenous leads. TPPM can be used as an alternative to standard temporary pacing leads when placement of a permanent pacemaker is contraindicated. We sought to determine the incidence and risk factors for early (within 6months) mortality(More)
BACKGROUND A widened electrocardiographic spatial QRS-T angle has been shown to be predictive of cardiovascular disease in HIV-infected individuals. However, determinants and risk factors of developing widened QRS-T angle over time in this population remain unknown. METHODS AND RESULTS Spatial QRS-T angle was automatically measured from standard(More)
BACKGROUND The improvement in discrimination gained by adding nontraditional cardiovascular risk markers cited in the 2013 American College of Cardiology/American Heart Association cholesterol guidelines to the atherosclerotic cardiovascular disease (ASCVD) risk estimator (pooled cohort equation [PCE]) is untested. OBJECTIVES This study assessed the(More)
BACKGROUND The significance of minor isolated Q waves in the resting electrocardiograms (ECGs) of apparently healthy individuals is unknown. OBJECTIVE To examine the association between minor isolated Q waves and incident cardiovascular disease events in the Multi-Ethnic Study of Atherosclerosis (MESA). DESIGN This analysis included 6551 MESA(More)
The relation between inflammation and prothrombotic state in atrial fibrillation (AF) is well recognized. This suggests a potential role for high-sensitivity C-reactive protein (hs-CRP), a marker of systemic inflammation, in improving prediction of stroke in participants with AF. Cox proportional hazard analysis was used to examine the risk of stroke in(More)
