Plasma norepinephrine concentration and plasma dopamine-beta-hydroxylase activity in patients with congestive heart failure.
The relationship between plasma norepinephrine (NE), epinephrine (E) and dopamine-beta-hydroxylase activity (DBH) was studied in 90 cardiac patients (New York Heart Association [NYHA] classes I-IV), 85 healthy control subjects and 18 competitive skiers. The cardiac patients in NYHA classes III and IV had significantly higher NE (p less than 0.001) and lower DBH (p less than 0.001) levels than t...
متن کاملPlasma digoxin concentration in children with heart failure.
A dosage schedule for digoxin medication is presented which has proved effective and safe in children of different ages with heart failure due to a variety of cardiac conditions. The plasma digoxin concentrations during maintenance therapy, using this schedule, agree closely with previously reported therapeutic adult plasma concentrations, though the results do not exclude the efficiency and sa...

متن کاملDiurnal variation in plasma norepinephrine in patients with heart failure.
Diurnal variation in plasma norepinephrine (PNE) levels is well documented in healthy individuals but not in patients with heart failure. Therefore, we attempted to determine variations in PNE levels over 24 hours, measured hourly, in six patients with an ejection fraction below 40% and a history of heart failure of longer than 3 months. Three controls without a history of heart failure also we...
متن کاملNorepinephrine spillover to plasma in patients with congestive heart failure: evidence of increased overall and cardiorenal sympathetic nervous activity.
The analysis of plasma kinetics of the sympathetic neurotransmitter norepinephrine can be used to estimate sympathetic nervous "activity" (integrated nerve firing rate) for the body as a whole and for individual organs. In 12 patients with cardiac failure (left ventricular ejection fraction 10% to 39%), the mean arterial plasma norepinephrine concentration was 557 +/- 68 pg/ml (mean +/- SE) com...
