[Therapy of the hypertensive crisis with urapidil. Various effects on patients with or without coronary disease].

The effect of urapidil on various hemodynamic and echocardiographic parameters has been investigated in 36 patients with hypertensive emergencies (14 patients with coronary artery disease, 22 patients without coronary artery disease). During treatment with urapidil, blood pressure decreased in both groups by 35%, the heart rate decreased slightly (3-8%). The mean pulmonary artery pressure decreased by 45% (coronary patients) respectively 36% (non-coronary patients), the pulmonary capillary wedge pressure by 59% (coronary patients) resp. 48% (non-coronary patients). Cardiac output increased in both groups by about 20%. In the echocardiogram, both groups showed decreases in the diameters of left atrium and left ventricle, and an increase in the fractional shortening of the left ventricle. Patients with coronary artery disease required less urapidil than non-coronary patients.
