The left ventricular contractility of the rat heart is modulated by changes in flow and a1-adrenoceptor stimulation
(1998-10)
Myocardial contractility depends on several mechanisms such as coronary perfusion pressure (CPP) and flow as well as on a1-adrenoceptor stimulation. Both effects occur during the sympathetic stimulation mediated by ...
Influence of the elevation of the left ventricular diastolic pressure on the values of the first temporal derivative of the ventricular pressure (dP/dt)
(Sociedade Brasileira de Cardiologia (SBC), 1999-07-01)
PURPOSE: To assess the effects of the elevation of the left ventricular end-diastolic pressure (LVEDP) on the value of the 1st temporal derivative of the ventricular pressure (dP/dt). METHODS: Nineteen anesthetized dogs ...
LEFT-VENTRICULAR MAXIMAL SYSTOLIC ELASTANCE CALCULATED BY A COMBINATION OF M-MODE ECHOCARDIOGRAPHY AND STANDARD MANOMETRY
(Associação Brasileira de Divulgação Científica (ABRADIC), 1991-01-01)
1. A method for obtaining the end-systolic left ventricular (LV) pressure-diameter and stress-diameter relationships in man was critically analyzed.2. Pressure-diameter and stress-diameter relationships were determined ...

Effect of left intraventricular pressure on magnitude of vascular waterfall in the epicardial coronary veins
(1990)
Study objective: The aim was to test the hypothesis of a vascular waterfall in the epicardial veins due to compression by the left ventricular (LV) pressure. If this were so, the epicardial venous pressure should be a ...
Effect of left intraventricular pressure on magnitude of vascular waterfall in the epicardial coronary veins
(Oxford University Press, 1990)
Study objective - The aim was to test the hypothesis of a vascular waterfall in the epicardial veins due to compression by the left ventricular (LV) pressure. If this were so, the epicardial venous pressure should be a ...
Aldosterone is associated with left ventricular hypertrophy in hemodialysis patients
(2016-10-01)
Objectives: Patients with chronic kidney disease present a higher degree of left ventricular hypertrophy than expected for hypertension levels. In chronic kidney disease the plot between the quotient extracellular water/total ...
Sex-related difference in left ventricular mass in nonhypertensive young adults: role of arterial pressure
(Pulsus Group Inc, 2012-08)
Blood pressure (BP) is higher in men than in women at similar ages through adult life. Interestingly, a similar pattern is detected in left ventricular mass (LVM), classically attributed to differences in body size. However, ...
Regression of left ventricular hypertrophy in essential arterial hypertension Reversión de la hipertrofia ventricular izquierda en la hipertensión arterial esencial.
(1994)
The classic concept of a direct pathogenic relationship between high blood pressure and development of left ventricular hypertrophy has been challenged by observations such as the modest correlations between blood pressure ...
Anthropometric measures of increased central and overall adiposity in association with echocardiographic left ventricular hypertrophy
(NATURE PUBLISHING GROUP, 2010)
Left ventricular hypertrophy is an important predictor of cardiovascular risk and sudden death. This study explored the ability of four obesity indexes (body mass index, waist circumference, waist-hip ratio and waist-stature ...
