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 ...
Lack of association between chronic exposure to biomass fuel smoke and markers of right ventricular pressure overload at high altitude
(Elsevier, 2014)
Chronic exposure to biomass fuel smoke has been implicated in the development of pulmonary hypertension and right ventricular pressure/volume overload through activation of inflammation, increase in vascular resistance, ...
Diverse effects of renal denervation on ventricular hypertrophy and blood pressure in DOCA-salt hypertensive rats
(1998-04)
Cardiac hypertrophy that accompanies hypertension seems to be a phenomenon of multifactorial origin whose development does not seem to depend on an increased pressure load alone, but also on local growth factors and ...
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 ...

Effects of mercury on the arterial blood pressure of anesthetized rats
(1999-08)
The available data suggests that hypotension caused by Hg2+ administration may be produced by a reduction of cardiac contractility or by cholinergic mechanisms. The hemodynamic effects of an intravenous injection of HgCl2 ...
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 ...

(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 ...
