[A new beta 1-receptor blocker in the therapy of essential hypertension and angina pectoris].

In 242 patients with hypertension and/or angina pectoris, a new cardioselective betablocker without ISA, bisoprolol (Concor), was tested. The average mean value of 168/102 mm Hg was lowered in the 174 hypertensive patients by a systolic value of 17 and a diastolic value of 11 mm Hg. A normal diastolic pressure of 95 mm Hg or below was attained within 4 weeks in 73% of patients. Angina pectoris improved from 7 attacks per week before treatment to 3 attacks after 2 weeks; patients with additional hypertension showed a further improvement after another two weeks to an average of 1.7 attacks per week. Side effects were most frequently dizziness, headache and fatigue and also a few patients with gastrointestinal symptoms, an unusual side effect with this treatment. The results show the effective antihypertensive and antianginal action of bisoprolol in a large group of outpatients.
