Left ventricular sphericity index predicts systolic dysfunction in rats with experimental aortic regurgitation
(Amer Physiological Soc, 2014-05-01)
Although an increased left ventricular (LV) diastolic diameter (DD) and a decreased ejection fraction have been used as markers for the surgical replacement of an insufficient aortic valve, these signals may be observed ...
Estudo Evolutivo da Morfologia e Função Cardíaca em Ratos Submetidos a Estenose Aórtica Supravalvar
(2003-12-01)
Objective - To characterize the follow-up of an experimental model of left ventricular hypertrophy (LVH) induced by supravalvular ascending aortic stenosis in young rats. Methods - Wistar rats were submitted to thoracotomy ...
Left ventricular mass estimated by M-mode echocardiogram is not altered by changes in cardiac shape and dimensions due to acute arterial hypertension.
(1993-01-01)
The effect of changes in left ventricular (LV) shape and dimensions due to acute arterial hypertension induced by mechanical obstruction of the aorta for 10 min on LV mass values estimated by M-mode echocardiogram was ...

N-Acetylcysteine Influence on Oxidative Stress and Cardiac Remodeling in Rats during Transition from Compensated Left Ventricular Hypertrophy to Heart Failure
(2018-01-01)
Background/Aims: To evaluate the effects of the antioxidant N-acetylcysteine (NAC) on cardiac structure and function in rats with long-term ascending aortic stenosis (AS). Methods: Four months after inducing AS, Wistar ...
Combined exercise training in asymptomatic elderly with controlled hypertension: Effects on functional capacity and cardiac diastolic function
(Int Scientific Literature, Inc, 2012-07-01)
Background: Aging is associated with changes in cardiac structure and function that are associated with left ventricular diastolic dysfunction. Whether diastolic functional alterations during senescence are manifestations ...
Long-axis fractional shortening and mitral annulus motion in dogs
(2016-09-01)
Ventricular systolic dynamics involves the contraction of transverse and longitudinal myocardial fibers. Unfortunately, only the activity of the transverse myocardial fibers is foreseen by the standard systolic echocardiographic ...
Effects of aerobic and resistance exercise on cardiac remodelling and skeletal muscle oxidative stress of infarcted rats
(2020-05-01)
We compared the influence of aerobic and resistance exercise on cardiac remodelling, physical capacity and skeletal muscle oxidative stress in rats with MI-induced heart failure. Three months after MI induction, Wistar ...
Association Between Left Ventricle Diastolic Dysfunction and Unfavorable Prognostic Markers in Patients with Aortic Insufficiency
(Premchand Shantidevi Research Foundation, 2017-06-01)
Introduction: The presence of symptoms, systolic dysfunction and Left Ventricle (LV) dilation are considered unfavourable prognostic markers in Aortic Valve Insufficiency (AVI). The role of diastolic dysfunction, which is ...
Clinical characteristics associated with unfavorable outcomes in peripartum myocardiopathyCaracterísticas clínicas associadas à evolução desfavorável na miocardiopatia periparto
(2005-01-01)
Objective: To assess the clinical characteristics of women with a previous diagnosis of peripartum myocardiopathy and to study the characteristics associated with unfavorable outcomes. Methods: Clinical, obstetric, and ...
