[Combined use of cold (chloroethyl) and ergometry tests in the diagnosis of vasospastic angina]

The study was undertaken to examine the informative value of cold (chloroethyl) and ergometrine tests in the diagnosis of vasospastic angina. A total of 36 patients with clinical and electrocardiographic signs of vasospastic angina were studied. They underwent coronary ventriculography, Holter monitoring, bicycle ergometry with continuously increasing or single submaximum exercise, pulmonary hyperventilation, cold, ergometrine, and chloroethyl tests. The examinations have shown that cold and ergometrine tests are of informative value in the diagnosis of vasospastic angina.
