| Popis: | We experienced a patient in whom coronary spasms were induced by an ergonovine provocation test during coronary angiography at the sites of coronary artery ectasia. The patient was a 45-year-old male with chest pain at rest, which promptly disappeared when given sublingual nitroglycerin. Similar attacks occurred frequently even with the administration of drugs after admission, but no significant changes were observed in electrocardiography (ECG) during the attacks or by repeated Holter ECG. The results of exercise ECG and provocation tests such as Valsalva maneuver, hyperventilation, and cold pressor test were negative. Coronary angiography showed ectatic changes in the left coronary artery, and the coronary spasms were induced by ergonovine administration at the ectatic portion of the left anterior descending artery and left circumflex artery, and right coronary artery with chest symptoms similar to those observed during spontaneous attacks. However, there were no significant changes in ECG. This rare case suggests an involvement of spasms in the pathogenic mechanism of myocardial ischemia in coronary artery ectasia. |
