Effects of captopril and a combination of hydralazine and isosorbide dinitrate on myocardial sympathetic tone in patients with severe congestive heart failure.
Changes in circulating catecholamines and transmyocardial catecholamine balance associated with improved left ventricular function were studied in patients with chronic heart failure after treatment with captopril (10 patients) and hydralazine in combination with isosorbide dinitrate (eight patients). Cardiac performance improved in response to both captopril and hydralazine-nitrate treatment. ...

renal response to oral hydralazine therapy in severe heart failure. Circulation 56 (suppl III): 111-9, 1977 33. Birch AA, Boyce WH: Changing renal blood flow following sodium nitroprusside in patients undergoing nephrolithotomy. SUMMARY Hydralazine is known to improve cardiac function in patients with congestive heart failure (CHF), but its effects on renal function in CHF are less clear. Sodiu...
متن کاملComparison of haemodynamic effects of oral hydralazine and prazosin hydrochloride in patients with chronic congestive heart failure.
The comparative haemodynamic effects of oral prazosin hydrochloride and hydralazine were evaluated in 11 patients with chronic congestive heart failure. The maximum total dose of prazosin received by an individual varied up to 25 mg. Ten patients received a maximum of 75 mg and one received 50 mg of hydralazine at six-hour intervals. There was no significant change in heart rate with either dru...
متن کاملPrecipitation of heart failure following sudden withdrawal of hydralazine.
Sudden withdrawal of oral therapy with hydralazine for reduction of afterload in a patient precipitated severe congestive heart failure. Signs of metabolic encephalopathy evolved due to low cardiac output. Reinstitution of therapy with hydralazine resulted in prompt improvement in cardiac and neurologic status. This case underscores the need for careful follow-up of such patients and argues aga...
متن کاملOral hydralazine therapy for chronic refractory heart failure.
The hemodynamic effects of oral hydralazine were investigated in ten patients (nine in NYHA Class IV and one in Class III) with chronic refractory heart failure. With hemodynamic monitoring, adequate oral doses of hydralazine (50 or 75 mg) were determined and then administered every six hours. Hemodynamics were determined at 2-3, 6-8 and 24 hours on hydralazine therapy. Arterial pressure decrea...
متن کاملHydralazine and isosorbide dinitrate: comparative central and regional hemodynamic effects when administered alone or in combination.
Central and regional hemodynamic studies were performed before and after the oral administration of 75 mg of hydralazine and/or 20 mg of isosorbide dinitrate in 15 patients with low-output congestive heart failure. Hydralazine increased mean cardiac output 17-25%, mean renal blood flow 19%, and limb blood flow 17% (all p < 0.05). Mean hepatic blood flow did not change significantly with hydrala...
