Journal of the American College of Cardiology, 2009 Heart failure with normal ejection fraction (HFNEF) is a common presentation in elderly persons and seems to have a prognosis almost as bleak as systolic heart failure. Much work on the pathophysiology of this entity has focused on left ventricular (LV) stiffness ([1][1])—indeed, stiffening ...

Left ventricular diastolic dysfunction: Early diastolic relaxation and late diastolic compliance
Journal of the American College of Cardiology, 1989 The fundamental importance of cardiac filling in regulating performance of the heart was recognized by Starling (I) early in this century. Development of comprehensive ventricular function curves by Sarnoff and others (la,2) beginning in the 1950s focused attention on the role of ventricular compliance in influencing cardiac pump performance by ...

Aging and Cancer, EarlyView.ABSTRACT Purpose To assess the long‐term effects of a community cancer exercise program on quality of life, fatigue, weight, waist circumference, physical activity levels, lower extremity strength, body mass index (BMI), heart rate, and blood pressure, across non‐metastatic and metastatic patients.

Current perspectives in diastolic dysfunction and diastolic heart failure [PDF]
Heart, 2006 Diastolic heart failure (HF) has emerged over the last two decades as a separate clinical entity. Approximately half of the patients presenting with symptoms of congestive HF exhibit a near normal left ventricular (LV) systolic function at rest, which is thought to be caused by a predominant abnormality in diastolic function. It is generally considered

Annals of Clinical and Translational Neurology, EarlyView.Abstract Objective Exploring the prevalence and association between intracranial atherosclerosis (ICAS) and cerebral small vessel diseases (CSVD), this study delved beyond the current scope, utilising high‐resolution vessel wall MRI (HRVW‐MRI) to investigate how subtle changes in intracranial atherosclerotic features influence the various burdens of ...

Diastolic and isoperimetric inequalities on surfaces [PDF]
Annales scientifiques de l'\'Ecole Normale Sup\'erieure, S\'erie
4, Tome 43 (2010) no. 4, pp. 579-605We prove a universal inequality between the diastole, defined using a minimax process on the one-cycle space, and the area of closed Riemannian surfaces. Roughly speaking, we show that any closed Riemannian surface can be swept out by a family of multi-loops whose lengths are bounded in terms of the area of the surface. This diastolic inequality, which

Vortex formation and instability in the left ventricle [PDF]
, 2011 We study the formation of the mitral vortex ring during early diastolic filling in a patient-specific left ventricle (LV) using direct numerical simulation. The geometry of the left ventricle is reconstructed from Magnetic Resonance Imaging (MRI) data of a healthy human subject.

Cerebral Amyloid Angiopathy Is Associated With Higher R2 Relaxation Rate: An MRI and Pathology Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Cerebral amyloid angiopathy (CAA) involves β‐amyloid deposition in the walls of cortical and leptomeningeal small vessels. Transverse relaxation rate (R2) is a major source of contrast in MRI. This study tested the hypothesis that CAA is associated with R2, extracted the spatial pattern of CAA‐related R2 abnormalities, and evaluated ...
