Bradykinin does not modulate the natriuretic response to atrial natriuretic factor in rats with aortocaval fistula.
Rats with aortocaval fistula, an experimental model of congestive heart failure (CHF), display two distinct patterns of sodium excretion: some rats develop marked sodium retention and worsening edema with urinary excretion of sodium (UNaV) < 200 microEq per 24 hours, i.e., uncompensated CHF, whereas in others sodium balance rapidly returns to normal (UNaV > 1,400 microEq per 24 hours), i.e., co...
متن کاملAngiotensin inhibition and atrial natriuretic peptide release after acute volume expansion in rats with aortocaval shunt.
OBJECTIVE In heart failure atrial natriuretic peptide (ANP) release in response to volume expansion is impaired while the renin-angiotensin system is activated. This study was designed to test the hypothesis that ANP release in heart failure is dependent on an activated angiotensin system. METHODS We studied the ANP and renin-angiotensin systems in a rat model of shunt-induced high-output hea...
متن کاملEvaluation of Serum Levels of N-terminal Pro Brain Natriuretic Peptide and Atrial Natriuretic Peptide in Neonates with Respiratory Distress
Background: Acute respiratory distress (ARD) is a critical respiratory failure due to lung injury of neonates leading to the clinical appearance of poor lung compliance. The aimed of the study was to evaluate the diagnostic values in differentiating respiratory from heart diseases with using of N-terminal pro brain natriuretic peptide (NT-pro BNP) and Atrial natriuretic peptide(ANP) in neonates...
متن کاملCardiac Myocyte Size in Rats With Aortocaval Fistulas
The effects of a large arteriovenous fistula on left and right ventricular hemodynamics and cardiac myocyte size were examined in adult rats at 1 week and 1 month after surgery. Cardiac output, left ventricular function, and right ventricular function were evaluated before obtaining isolated myocytes for cell size measurements. Average heart weight increased 35% at 1 week and 86% at 1 month in ...
متن کاملAbnormal rhythmic oscillations of atrial natriuretic peptide and brain natriuretic peptide in heart failure.
The purpose of this study was to clarify whether the secretions of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) are pulsatile in patients with chronic heart failure (CHF), and whether the rhythmic oscillations for ANP and BNP are abnormal in patients with CHF. Several reports have shown that ANP and especially BNP are valuable indicators of the prognosis in CHF. Previous...
