Abstract: | The state of coronary arteries was assessed by means of angiography, and coronary-bed tendency to spastic response was assessed by the ergometrin test in 76 patients with angina of new onset (several days to 2 months since the first symptoms). It is suggested that coronary spasm as well as the rate and extent of development of collateral anastomoses in response to stenosing events in the coronary arteries are as important as the anatomical factor in the pathogenesis of angina. Aorto-coronary shunting is possible in most of such patients. |
