چکیده

Background Coronary artery remodeling is an indicator of coronary artery disease. Morphological and biomechanical changes accompany with coronary wall remodeling. Such changes can be noninvasively detected using MR imaging and may be used to predict cardiovascular events. The aim of this study is to assess interrelations among various imaging markers of the coronary remodeling in older hypertensive patients.

Potential quantitative magnetic resonance imaging biomarkers of coronary remodeling in older hypertensive patients.

OBJECTIVE To detect differences in potential magnetic resonance imaging biomarkers of coronary remodeling between older hypertensive patients and healthy controls. METHODS AND RESULTS Two-dimensional black-blood coronary wall magnetic resonance imaging and 3-dimensional whole-heart coronary magnetic resonance angiography were performed on 130 participants (65-84 years), including 65 hypertens...

The Effect of Cardiac Rehabilitation on Left Ventricular Remodeling in Men and Women Patients with Coronary Artery Disease

Objective: Left ventricular (LV) remodeling is associated with increased morbidity and mortality therefore, interventions that halt or reverse ventricular remodeling are expected to prevent these clinical outcomes. The aim of the study was to assess the effects of cardiac rehabilitation program on cardiac remodeling process in patients with coronary artery disease and then compare the results b...

Vascular Mineralocorticoid Receptors

Cardiovascular disease is often delineated as a continuum from risk factors leading to organ damage, remodeling, and finally dysfunction. The vasculature is ascribed a central role in that model: major cardiovascular risk factors such as the metabolic syndrome or age are closely associated with chronic inflammation and oxidative stress driving impaired nitric oxide bioavailability, endothelial ...

Reduced coronary flow reserve and arterial stiffness: two faces of the same coin.

T he heart and the arterial tree are strongly associated, not only anatomically but also functionally. The cardiovascular (CV) system has the ability to regulate cardiac output and arterial blood pressure, and to respond to changes in heart rate and preload appropriately. This CV link depends largely on the properties of both the heart and of the vasculature into which blood is pumped and becom...

Imaging Prevalence and Clinical Significance of Papillary Muscle Infarction Detected by Late Gadolinium-Enhanced Magnetic Resonance Imaging in Patients With ST-Segment Elevation Myocardial Infarction

Background—The frequency of papillary muscle infarction (PapMI) without rupture has not been fully investigated in vivo. Furthermore, the relationship between papillary muscle dysfunction and mitral regurgitation (MR) has been controversial in patients with ST-segment elevation myocardial infarction. Therefore, the aim of this study was to assess the frequency and clinical characteristics of Pa...
