Experiments were performed on isolated coronary arteries to determine whether or not lidoflazine, an agent reported to be beneficial in the treatment of angina pectoris, is effective in antagonizing coronary vasoconstriction. Segments of canine circumflex and right coronary arteries were suspended

1. Canine coronary arteries with intact endothelium respond to hypoxaemia or serotonin infusion with dilatation, but when the endothelium is injured or dysfunctional, these stimuli can cause constriction. The present studies investigated whether or not regional ischaemia and reperfusion alter

Spontaneous phasic activity of isolated human coronary arteries.

The functional behaviour and pharmacological responses of ring segments of large coronary arteries removed from five patients undergoing cardiac transplantation were studied in vitro. All segments showed spontaneous rhythmic contractions which were markedly dependent on external calcium and were

The role of intimal hyperplasia in arterial spasm.

Ní féidir ach le húsáideoirí cláraithe ailt a aistriú
Logáil Isteach / Cláraigh
It has been postulated that even moderate spasm in an artery with intimal hyperplasia can produce organ hypoxia because there is an excessive reduction in the diameter of the lumen. To test this hypothesis we created intimal hyperplasia in one femoral artery in five pigs and then induced arterial
An animal model of coronary artery spasm-coronary thrombosis-acute myocardial infarction (CAS-CATH-AMI) was obtained by injecting ergonovine(0.22 mg/kg) directly into the left coronary artery (LCA) of 17 dogs under general anesthesia. Various parameters of the experimental group were compared with
