Response of Atrial Natriuretic Factor to Acute and Chronic Increases of Atrial Pressures in Experimental Heart Failure in Dogs
Background. This study evaluated the role of changes in heart rate, atrial pressure, volume, and cardiac tissue atrial natriuretic factor (ANF) concentration in the modulation of plasma ANF concentration in a model of pacing-induced heart failure. Methods and Results. The effects of acute right ventricular pacing (250 beats/min), acute volume expansion (35 ml/mmn), and volume expansion after 1 ...
متن کاملRadiocontrast induced nephropathy.
In spite of improvements in chemical structure, contrast media assisted X-ray examination is still the third leading cause of hospital-acquired acute renal failure. An increase >50% or >88 micro mol/L in S-creatinine is a clinically important acute renal failure. The peak in S-creatinine occurs within 2-5 days after exposure. The frequency of oliguria, transient or permanent haemodialysis is un...
متن کاملLow-dose atrial natriuretic factor and furosemide in experimental acute congestive heart failure.
This study was designed to address three objectives in an experimental model of acute congestive heart failure (CHF) in the dog produced by rapid ventricular pacing. The first objective was to characterize cardiorenal and humoral responses before and during 2 h of acute CHF. The second objective was to determine the modulating action of iv furosemide upon these biologic responses to acute CHF, ...
متن کاملIntra-Arterial Atrial Natriuretic Peptide in Patients With Heart Failure
It has been shown that renal responses to atrial natriuretic peptide (ANP) are markedly attenuated in patients with heart failure. This study aimed to determine if vasodilative response to ANP is altered in patients with heart failure. In patients with heart failure (n=7) and age-matched normal subjects (n=7), forearm blood flow was measured using a strain-gauge plethysmograph during intra-arte...
متن کاملA primer in radiocontrast-induced nephropathy.
Despite recent medical progress in supportive medical absent, DM present (n=318); (iii) RI present, DM absent (n=298); (iv) both RI and DM present (n=216) therapy, the frequency of hospital-acquired acute renal failure has increased in recent years from ~5% to [14]. The frequency of RCIN, defined as an increase of serum creatinine 0.5 mg/dl, was 8.5% for iohexol (I ) 6.4% [1,2]. Even more distr...
