Abstract
A working hypothesis on pathogenesis of ischemic heart damage has been proposed. According to this hypothesis, a crucial role in conversion of reversible damage into irreversible damage is played by cardiomyocyte membrane destruction caused by the so-called “lipid triad”. The latter comprises activation of lipid peroxidation, activation of phospholipases, and the degergentlike action of excessive amounts of free fatty acids and lysophospholipids. Marked activation of lipid peroxidation in experimental myocardial infarction, as well as reoxygenation following transitory ischemia, have been demonstrated. The proposed hypothesis and experimental data underly successful application of synthetic free radical scavengers (antioxidants) for heart protection against experimental myocardial infarction, transitory ischemia, and emotional, painful stress. In der vorliegenden Studie wird eine Arbeitshypothese zur Pathogenese der ischämischen Herzschädigung aufgestellt. Nach dieser Hypothese ist ein entscheidender Faktor für den Übergang von der reversiblen zur irreversiblen Schädigung eine Membrandestruktion der Herzmuskelzellen, welche durch sog. Lipid-Triaden verursacht wird. Letztere beinhaltet eine Aktivierung der Lipid-Peroxidation und der Phospholipase sowie eine Detergenz-ähnliche Wirkung exzessiver Mengen von freien Fettsäuren und Lysophospholipiden. Eine ausgepräge Aktivierung der Lipid-Peroxidation beim experimentellen Herzinfarkt sowie eine Reoxigenierung nach vorübergehender Ischämie wurden demonstriert. Die vorgelegte Hypothese und die experimentellen Daten legen eine Anwendung von Radialfängern (Antioxidantien) nahe für die Protektion des Herzens gegen experimentellen Myokardinfarkt, vorübergehende Ischämie und emotionalen Streß bei Schmerzsituationen.Keywords
