Restriction of isoproterenol-induced myocardial Ca uptake and necrotization in rats by a new Ca-antagonistic compound (ethyl-4-(3,4,5-trimethoxycinnamoyl) piperazinyl acetate (Vascordil)).

Abstract

As shown in previous investigations overdoses of isoproterenol produce an abundant myocardial Ca uptake, followed by high energy phosphate breakdown, mitochondrial damage and, eventually, cardiac fibre necrotization. Conversely Ca antagonistic compounds such as verapamil, D 600 or prenylamine which reduce the transmembrane Ca influx into the heart muscle… (More)
