Abstract:
Objective To examine the clinical effects of intravenous lyophilize recombinant human brain natriuretic peptide (rhBNP) in patients with refractory heart failure caused by coronary artery disease.Methods Seven patients with refractory heart failure caused by coronary artery disease were treated with rhBNP.The rhBNP nea grade,symptoms and signs,24 hours urine output,heart rate,blood pressure and central venous pressure were evaluated at 0,15,30 min and 1,2,4,8,12,24,and 48 h.Serum potassium,sodium,creatinine and plasma BNP before and after treatment were measured.Results After rhBNP therapy,dyspnea grade were improved in 5 patients.Symptoms and signs got better in 6 patients.Systolic blood pressure at 15 min of treatment distolic blood pressure was decreased slightly from (112.00±10.42) mm Hg to (105.14±7.76) mm Hg (P＜0.05) and became (108.71±6.63)mm Hg at 30 rain which was the same with that before treatment.There was no statistical significance in heart beat[ ( 88.57±16.92 ) vs.( 86.00±16.21 ) ] beat/min,serum sodium [ ( 133.57±5,38 ) mmol/Lvs.( 133.57±8.16) mmol/L ],serum potassium [ (3.83±0.37) mmol/L vs.(4.19±0.58 ) mmol/L ],ereatinine [ (93.11±27.90) μmol/L vs ( 123.01±93.01 ) μmol/L ] before and after treatment,and BNP[ ( 1218.43±847.83) vs.(1433.71±676.08)ng/L] before treatment and at24 h treatment,as well as urine output [(2329±1573 ) vs.(2126±1074) ml ] ( P ＞ 0.05 ).Urine output was increased during the treatment,but the usage of diuretic was remarkably decreased.Central venous pressure was gradually decreased from 30 rain to 48 h( P ＜ 0.05 ).Condusion rhBNP can decrease central venous pressure and increase urine output with exerts little side effects on electrolytes and renal function.Therefore rhBNP has positive clinical effects on refractory heart failure which is caused by coronary artery disease.
