Abstract

The effect of reoxygenated coronary effluent of an isolated guinea-pig heart on a sequentially perfused second heart, right auricle trabecula and arterial vessel rings was studied after 20 min ischaemia of the first heart. It has been shown that a factor released after myocardial ischemia/reperfusion stimulates arrhythmia, decreases myocardial contractility of the second heart and depresses tonical tension of the right auricle trabecula and arterial vessel rings. Storage of the coronary effluent up to 24 h did not modify its effects. These results suggest stable factor released from an isolated heart after ischaemia at reperfusion to exert humoral effect not only on a myocardial contractility and coronary circulation but on the peripheral vessels tonus.
