A RARE FORM OF PROGRESSION OF SPASTIC ANGINA WITH NORMAL CORONARY-ARTERIES

The authors report the case of a 65-year-old woman smoker monitored for spastic angina. A first coronary arteriogram in 1986 failed to reveal any significant coronary lesion and was complicated by reversible occlusive spasm of the anterior interventricular artery. A second coronary arteriogram 6 years later because of recurrence of angina revealed the development of 70 % stenosis of the coronary segment affected by the spasm. Such an outcome is rarely reported in the literature and raise the question of a possible link between spasm and the progression of atheroma.
