Urapidil has been proposed to be an effective vasodilator for the treatment of
acute decompensated heart failure (ADHF); however, its effect on cardiac
function, as compared with that of nitroglycerin, in elderly patients with
hypertension and ADHF has yet to be determined. In the present study, a
multicenter, open-label clinical trial was performed, in which 120 elderly
patients with hypertension and ADHF were randomly assigned to the treatment
(50-400 µg/min intravenous urapidil) or control group (5-40 µg/min intravenous
nitroglycerin). The dosages of the medications were adjusted according to the
blood pressure of the patients. The systolic and diastolic blood pressure, heart
rate and serum level of N-terminal pro B-type natriuretic peptide (NT-proBNP)
were evaluated at hospital admission and at days 1, 2, 3 and 7 after treatment.
In addition, the left ventricular function was assessed by measuring the left
ventricular ejection fraction (LVEF) and left ventricular end-diastolic volume at
hospital admission and at days 2 and 7 after treatment. The results indicated
that intravenous administration of urapidil and nitroglycerin were effective in
lowering the blood pressure and heart rate within 7 days, with no significant
differences observed between the two groups (P>0.05). By contrast, greater
reduction in the serum NT-proBNP level (2,410.4±546.1 vs. 4,234.1±876.4 pg/ml;
P<0.05) and greater improvement in the LVEF (55.3±3.4 vs. 45.2±2.4%; P<0.05) were
observed in the urapidil-treated group, as compared with the
nitroglycerin-treated group. No adverse events were reported during the treatment
period in the two groups. The clinical outcomes at 6 months following discharge
were evaluated and were not found to be significantly different between the two
groups. In conclusion, the present results of the present study suggested that
urapidil was as effective as nitroglycerin in controlling blood pressure and
heart rate and was more effective in improving cardiac systolic function in
elderly patients with hypertension and ADHF.
