Coronary magnetic resonance angiography (CMRA) is a technique in clinical evolution. Current clinical applications include assessment for coronary anomalies, aneurysms, bypass graft patency, and, in experienced centers, the exclusion of proximal and multivessel coronary artery disease (CAD). As local expertise increases and more extensive multicenter data(More)
Left atrial (LA) volume is associated with cardiovascular morbidity, particularly atrial fibrillation. Contrast-enhanced magnetic resonance angiography (CE-MRA) visualizes the LA, but the validity of LA volume measurements using this technique has not been evaluated. We performed CE-MRA and cine magnetic resonance (MR) in 18 consecutive patients referred(More)
OBJECTIVES We sought to assess whether statins may decrease cardiac complications in patients undergoing noncardiac vascular surgery. BACKGROUND Cardiovascular complications account for considerable morbidity in patients undergoing noncardiac surgery. Statins decrease cardiac morbidity and mortality in patients with coronary disease, and the beneficial(More)
BACKGROUND The advent of fibrin-binding molecular magnetic resonance (MR) contrast agents and advances in coronary MRI techniques offers the potential for direct imaging of coronary thrombosis. We tested the feasibility of this approach using a gadolinium (Gd)-based fibrin-binding contrast agent, EP-2104R (EPIX Medical Inc), in a swine model of coronary(More)
PURPOSE To address degradation of coronary MR angiography (MRA) image quality due to heart rate variability (HRV)-associated variations in coronary artery position and motion. MATERIALS AND METHODS Free-breathing navigator-gated and -corrected coronary MRA using subject-specific trigger delays and acquisition windows was combined with a real-time HRV(More)
OBJECTIVES We sought to develop a reproducible method for characterizing the anatomy of the proximal pulmonary veins. BACKGROUND Contrast-enhanced three-dimensional magnetic resonance angiography (CE-MRA) is a commonly requested test before and after radiofrequency ablation for the treatment of atrial fibrillation. While CE-MRA readily visualizes the(More)
BACKGROUND The effect of raloxifene on aortic elasticity in healthy postmenopausal women is unknown. The purpose of the present study was to examine the effect of raloxifene on aortic elasticity and cardiovascular structure and function in healthy postmenopausal women. METHODS A randomized, crossover, double-blind, placebo-controlled clinical trial was(More)
Angiotensin converting enzyme (ACE) promotes cardiac fibrosis. LV myocardial deformation and torsion are markers of subclinical myocardial dysfunction. We investigated the association of serum ACE levels with LV deformation markers in untreated hypertensives. In 120 untreated patients (age: 53.5 ± 11.2 years) with essential hypertension and 60 healthy(More)
