[Modification of the isoprenaline-induced myocardial necrosis using trapidil].
Trapidil increases the isoprenalin-induced necrosis of the myocardium in the rat. In the paper is referred to the importance of the term of application in relation to the application of the infarcting noxa. Trapidil has a particularly unfavourable effect, if it is given after isoprenalin. The shift of the relation from the oxygen requirement to the oxygen supply by beta-adrenergic stimulation is regarded as an equivalent for the acute ischaemia. The authors see a connection between the phosphodiesterase-inhibiting activity of trapidil and the influence of the size of necrosis after the application of isoprenalin in the rat. These findings have also clinical importance, as the area of indication explicitly includes the application after fresh myocardial infarction and in acute pectanginous attack.
