BACKGROUND: Interleukin (IL)-12 activity is involved in the pathogenesis of psoriasis and acute coronary syndromes. We investigated the effects of IL-12 inhibition on vascular and left ventricular (LV) function in psoriasis. METHODS AND RESULTS: One hundred fifty psoriasis patients were randomized to receive an anti-IL-12/23 (ustekinumab, n=50), anti-tumor necrosis factor-a (TNF-α; etanercept, n=50), or cyclosporine treatment (n=50). At baseline and 4 months post-treatment, we measured (1) LV global longitudinal strain, twisting, and percent difference between peak twisting and untwisting at mitral valve opening (%untwMVO) using speckle-tracking echocardiography, (2) coronary flow reserve, (3) pulse wave velocity and augmentation index, (4) circulating NT-proBNP (N-terminal pro-B-type natriuretic peptide), TNF-α, IL-6, IL-12, IL-17, malondialdehyde, and fetuin-a...

BACKGROUND: Presence of prominent left ventricular trabeculation satisfying criteria for left ventricular noncompaction (LVNC) on routine cardiac magnetic resonance examination is frequently encountered; however, the clinical and prognostic significance of these findings remain elusive. This registry aimed to assess LVNC prevalence by 4 current criteria and to prospectively evaluate an association between diagnosis of LVNC by these criteria and adverse events. METHODS AND RESULTS: There were 700 patients referred for cardiac magnetic resonance: 42% were women, median age was 70 years (range, 45-71 years), mean left ventricular ejection fraction was 51% (±17%), and 32% had late gadolinium enhancement on cardiac magnetic resonance...

BACKGROUND: Optical coherence tomographic (OCT) morphologies associated with lesion progression are not well studied. The aim of this study was to determine the morphological change for untreated lesion progression using both OCT and intravascular ultrasound (IVUS). METHODS AND RESULTS: We used baseline and 8-month follow-up 3-vessel OCT and IVUS to assess 127 nonculprit lesions (IVUS plaque burden ≥40%) in 45 patients with stable angina after target lesion treatment...

BACKGROUND: Electromechanical discoordination may contribute to long-term pulmonary right ventricular (RV) dysfunction in patients after surgery for congenital heart disease. We sought to evaluate changes in RV function after temporary RV cardiac resynchronization therapy. METHODS AND RESULTS: Twenty-five patients aged median 12.0 years after repair of tetralogy of Fallot and similar lesions were studied echocardiographically (n=23) and by cardiac catheterization (n=5) after primary repair (n=4) or after surgical RV revalvulation for significant pulmonary regurgitation (n=21)...

BACKGROUND: Hypertensive left ventricular hypertrophy (HTN-LVH) is a leading cause of heart failure. Conventional patterns of cardiac geometry do not adequately risk-stratify patients with HTN-LVH. Using cardiovascular magnetic resonance, we developed a novel Remodeling Index (RI) that was designed to detect an exaggerated hypertrophic response to hypertension and tested its potential to risk-stratify hypertensive patients. METHODS AND RESULTS: The RI was derived using LaPlace's Law (), and normal RI ranges were established in 180 healthy volunteers...

BACKGROUND: Late gadolinium enhancement (LGE) border zone on cardiac magnetic resonance imaging has been proposed as an independent predictor of ventricular arrhythmias. The purpose was to determine whether size and heterogeneity of LGE predict appropriate implantable cardioverter defibrillator (ICD) therapy in ischemic cardiomyopathy (ICM) and nonischemic cardiomyopathy (NICM) patients and to evaluate 4 LGE border-zone algorithms. METHODS AND RESULTS: ICM and NICM patients who underwent LGE cardiac magnetic resonance imaging prior to ICD implantation were retrospectively included...

BACKGROUND: Detailed understanding of regional function after myocardial infarction (MI) is currently incomplete. We aimed at investigating regional myocardial strain and work in post-MI rats with and without heart failure. METHODS AND RESULTS: Six weeks after induction of MI, 62 male Wistar-Hannover rats with a range of infarct sizes, plus 14 sham-operated rats, were examined by cine and phase-contrast magnetic resonance imaging. After magnetic resonance imaging, the rats were catheterized, and left ventricular pressures were recorded...
