Diastolic dysfunction types in the prediction of viable myocardium functional recovery [PDF]
Vojnosanitetski Pregled, 2008 Background/Aim. It is well known that patients with coronary artery disease and viable tissue as a guarantee of contractile recovery (CR), despite of decreasing ejection fraction (EF) and systolic dysfunction, could have benefit from surgical ...

Left ventricular active stiffness: dependency on time and inotropic state [PDF]
, 1978 Left ventricular systolic stiffness was measured by rapidly changing ventricular volume (within 7 ms) of isovolumically contracting isolated rabbit hearts. Instantaneous pressure-volume relations were found to be linear with slopes that depended upon the

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

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 ...

Convective instability and transient growth in steady and pulsatile stenotic flows [PDF]
, 2008 We show that suitable initial disturbances to steady or long-period pulsatile flows in a straight tube with an axisymmetric 75%-occlusion stenosis can produce very large transient energy growths.

The Turkish Journal of Pediatrics, 2019 Regular blood transfusions for children with beta thalassemia major (β- TM) results in iron overload cardiomyopathy/cardiac failure. Mortality in these children is most often because of heart failure.

Investigating inter-turn fault in transformer using TTR and FRA [PDF]
, 2019 Transformers are one of the significant elements in the power system network. The Transformer function is to step up and down the voltages. When the transformer operating in high load, it exposes to failures.

Diastolic dysfunction in cardiomyopathies
Journal of Cardiovascular Echography, 2011 Abstract Introduction Cardiomyopathies are diseases of the heart muscle, with frequent genetic component, characterized by a strong heterogeneity concerning clinical presentation and echocardiographic profile. Diastolic dysfunction can affect all forms of cardiomyopathy, often being an expression of a more advanced state of the disease ...

The Heart of a Horse: 3‐D Echocardiographic Analysis of the Equine Aortic Valve [PDF]
, 2019 Aortic regurgitation (AR) can be a normal function of aging or a disease in younger horses. Symptoms range from no outward signs to decreased performance to sudden cardiac arrest.

Increased baseline ECG R-R dispersion predicts improvement in systolic function after atrial fibrillation ablation. [PDF]
, 2019 BackgroundAtrial fibrillation (AF) is associated with left ventricular (LV) systolic dysfunction which may improve after AF ablation. We hypothesised that increased ventricular irregularity, as measured by R-R dispersion on the baseline ECG, would ...
