Diagnosis of Heart Failure with Preserved Ejection Fraction
Heart Failure Clinics, 2014 Heart failure with preserved ejection fraction (HFpEF) constitutes a growing health care burden worldwide. Although definitions vary somewhat among guidelines, in general the presence of typical heart failure symptoms and signs in combination with a preserved left ventricular ejection fraction (≥50%) and functional and/or structural left ventricular ...

SEP acceleration in CME driven shocks using a hybrid code [PDF]
, 2014 We preform hybrid simulations of super Alfvenic quasi-parallel shock, driven by a Coronal Mass Ejection (CME), propagating in the Outer Coronal or Solar Wind at distances of between 3 to 6 solar radii. The hybrid treatment of the problem enable the study of the shock propagation on the ion time scale, preserving ion kinetics and allowing for a self ...

Heart Failure With a Preserved Ejection Fraction
Journal of the American College of Cardiology, 2011 The terminology for what has become the most common form of heart failure ([1][1]) has evolved in the medical literature. Two decades ago, Kitzman et al. ([2][2]) studied a small group of patients with heart failure and normal left ventricular ejection fraction and demonstrated that exercise ...
