OBJECTIVES This study sought to evaluate indexes of pulmonary artery (PA) stiffness in patients with pulmonary hypertension (PH) using same-day cardiac magnetic resonance (CMR) and right heart catheterization (RHC). BACKGROUND Pulmonary artery stiffness is increased in the presence of PH, although the relationship to PH severity has not been fully(More)
Using cardiac magnetic resonance, the presence of myocardial delayed contrast enhancement (DCE) has been described in the ventricular septum at the level of the right ventricular insertion points in patients with pulmonary hypertension (PH). The aim of this study was to investigate the prevalence, extent, and correlates of this finding. Septal DCE was(More)
Prior small studies have shown multiple benefits of frequent nocturnal hemodialysis compared to conventional three times per week treatments. To study this further, we randomized 87 patients to three times per week conventional hemodialysis or to nocturnal hemodialysis six times per week, all with single-use high-flux dialyzers. The 45 patients in the(More)
PURPOSE To evaluate the feasibility of a multi-station three dimensional (3D) T1-weighted turbo spin echo (TSE) dark-blood Sampling Perfection with Application optimized Contrasts using different flip angle Evolution sequence (T1w-SPACE), to assess aorta, iliac, and superficial femoral (SFA) arteries (inflow vessels) by comparing it with a multi-station(More)
Angiotensin receptor blockers have been hypothesized to have synergistic effects with statins. We evaluated the effects of valsartan alone or combined with simvastatin on blood pressure (BP) and indexes of inflammation and oxidant stress in hypertensive patients with hyperlipidemia. In this double-blind trial, 404 patients were randomized to 12 weeks(More)
To date, no study has evaluated the short- and long-term effects air pollution exposure on emphysematous subjects who have undergone lung volume reduction surgery (LVRS). Data from the National Emphysema Treatment Trial study (1998-2003) included 1,218 subjects, aged 39 to 84. Daily values of ambient fine particulate matter (aerodynamic diameter < 2.5 μm;(More)
The renin-angiotensin system (RAS) may play a role in vascular aging. The authors hypothesized that blockade of the angiotensin II type 1 receptor with an angiotensin receptor blocker in healthy elderly subjects improves vascular compliance and endothelial function. Thirty-five healthy elderly subjects were randomized to valsartan or placebo in a(More)
OBJECTIVES Epidemiologic studies have documented a disproportionate burden of chronic diseases in Appalachia, showing the area to be underserved by the health-care system. Nothing is known about how the health status of the Appalachian population compares with other rural or non-rural populations in the same state. We examined the associations among county(More)
