OBJECTIVES The purpose of this study was to prospectively investigate the diagnostic and prognostic impact of cardiac magnetic resonance (CMR) T1 mapping and validate it against left ventricular biopsies. BACKGROUND Extracellular volume (ECV) expansion is a key feature of heart failure. CMR T1 mapping has been developed as a noninvasive technique to(More)
*Does not include myectomy associated with valve replacement, coronary artery bypass grafting, or resection of a subaortic membrane. †Within 30 days of the myectomy. ‡Includes 2 patients with prior alcohol septal ablation; with these 2 patients considered nonpure myectomies, the Mayo mortality rate would be only 0.15%. §Includes 19% of patients with mitral(More)
The polymerase chain reaction (PCR) was used to investigate the presence of positive and negative hepatitis C virus (HCV) RNA strands in serum and peripheral blood mononuclear cells (PBMC) of 20 patients with histologically proven HCV-related chronic liver disease. All patients completed a course of interferon (IFN) treatment (6 MU of IFN-alpha 2b three(More)
AIMS Recent data indicate that right ventricular systolic dysfunction (RVSD) by cardiac magnetic resonance imaging (CMR) is a strong predictor of outcome in heart failure. However, the prognostic significance of RVSD by CMR in heart failure with preserved ejection fraction (HFpEF) is unknown. METHODS AND RESULTS We prospectively enrolled 171 HFpEF(More)
BACKGROUND Patients with heart failure with preserved ejection fraction have functional impairment resulting in reduced quality of life. Specific pathological mechanisms underlying symptoms have not yet been defined. OBJECTIVES The aim of this study was to identify hemodynamic and other patient-related variables that are associated with New York Heart(More)
OBJECTIVES This study sought to define the prognostic significance and clinical determinants of the 6-min walk distance (6-MWD) in affected patients. BACKGROUND Symptoms of exertional fatigue and dyspnea, as well as a reduced exercise tolerance, are cardinal features of pulmonary hypertension associated with heart failure and preserved ejection fraction(More)
BACKGROUND Heart failure with preserved ejection fraction (HFpEF) is recognized as a major cause of cardiovascular morbidity and mortality. Thus, a profound understanding of the pathophysiologic changes in HFpEF is needed to identify risk factors and potential treatment targets in this specific patient population. Therefore, we aimed to comprehensively(More)
AIMS Circulating soluble neprilysin, an endopeptidase that catalyses the degradation of various endogenous vasodilators, predicts outcome in patients with heart failure and reduced ejection fraction (HFrEF). In the present study, we measured for the first time circulating soluble neprilysin in a prospective cohort of patients with heart failure with(More)
BACKGROUND Previous work indicates that dilatation of the pulmonary artery (PA) itself or in relation to the ascending aorta (PA:Ao ratio) predicts pulmonary hypertension (PH). Whether these results also apply for heart failure with preserved ejection fraction (HFpEF) is unknown. In the present study we evaluated the diagnostic and prognostic power of PA(More)
