Selective coronary angiography has shown that typical @entity951 may occur in the absence of @entity3979 . Other causes of these attacks of @entity158 have been found: @entity3361 , @entity4785 or metabolic disturbances of the myocardial cell. Of all the @entity1 undergoing coronary angiography in 1984 at the Centre Cantini, 9 had no classical coronary lesions but delayed filling of the left anterior descending artery. This syndrome was described for the first time in 1972 by Tambe as the "slow @entity450 ". The aim of this study was to analyse the clinical, ECG and haemodynamic profiles of those @entity1 . Five of them also underwent stress Thallium myocardial scintigraphy. An @entity3693 provocation test was performed afterwards under ECG control. @entity245 was appreciated by comparison with the other vessels and also by measuring the filling time which was two or three times longer than in a control series of 9 @entity1 with @entity951 and normal coronary arteries. The difference was statistically significant. These findings were only observed in strictly normal coronary vessels; they were reproducible and unaffected by the administration of @entity1507 derivatives. In our series all 9 @entity1 were @entity1 with an average age of 51.4 years. One @entity1 was asymptomatic and had a history suggestive of @entity583 , and 4 others had typical @entity951 of effort: all had abnormal exercise stress tests. The other 3 @entity1 had spontaneous atypical @entity662 , normal resting ECG and a negative exercise stress test (impossible in one case). The five stress Thallium scintigraphies showed myocardial perfusion defects.(ABSTRACT TRUNCATED AT 250 WORDS)
