[Cardiac output and central-hemodynamic parameter under bencyclan (author's transl)].

In 17 patients with peripheral arterial occlusive disease the influence of intra-veinously applicated Bencyclane (Fludilat) on cardiac output and central-hemodynamic parameter has been investigated. While 100 mg (n = 8) of Bencyclane almost do not influence cardiac output, 200 mg (n = 9) cause a significant decrease of minute-volume of the heart by-17.22% and of heartfrequency by-8.85%. With either dose there is also a significant increase of aortic pressure, pulmonary arterial pressure and pulmonary vessel resistance to be seen. These results correlate with the animal-experimental proof of a negative inotropy under Bencyclane, and they have to be considered in therapeutical use.
