[Risks of treatment with beta-blocking agents in acute XXXX (author's transl)].

@entity1 @entity583 @entity64 @entity1169
Haemodynamic investigations were performed in 40 @entity1 with acute @entity583 before and after intravenous application of 6 mg @entity1169 . Cardiac index was significantly decreased caused by reduction of cardiac frequency and @entity64 volume. Pulmonary capillary pressure increased significantly. As a consequence pulmonary and peripheral vascular resistance increased. Arterial blood pressure remained largely unaffected. @entity1169 showed a haemodynamically beneficial decrease of left @entity64 without signs of negative cardiodepression at a cardiac index of more than 3.0 l/min . m2. At a cardiac index of less than 3.0 l/min . m2 a haemodynamically detrimental lowering of cardiac index to ranges of insufficiency of 2.0 l/min . m2 on average occurred. Thus cardiac index is an important factor for the decision of use of beta-blocking agents in acute @entity583 . Indiscriminate use of beta-blocking substances should not be accepted.
