  • Title: Effect of chloroquine in experimental myocardial ischaemia.
    Author: Fazekas T, Szekeres L.
    Journal: Acta Physiol Hung; 1988; 72(2):191-9. PubMed ID: 3227859.
    Abstract:
    The cardiac effects of the phospholipase A2 inhibiting agent chloroquine were studied in dogs, rats and cats. During left anterior descending coronary artery occlusion produced in anaesthetized mongrel dog, chloroquine pretreatment considerably reduced the epicardial ST-segment elevation in the ischaemic area, as well as the number of premature ventricular contractions. In conscious male Sprague-Dawley CFY rats it diminished the duration and prolonged the latency of appearance of the early post-infarction arrhythmias and increased the survival rate following coronary artery ligation. Chloroquine failed to affect the ventricular fibrillation threshold in the normoxic cat heart. The cardioprotective action of chloroquine could be explained at least partly by its antiphospholipase activity.
