BACKGROUND AND AIMS: Coronary angiography permits evaluation of coronary artery morphology and coronary pathology. It represents an accurate method of defining stenotic coronary lesions. @entity662 may be caused by @entity453 as well as by other @entity299 . However, sensitivity of clinical evaluation and noninvasive diagnostic assessment in detection of @entity453 is limited. Noninvasive diagnostic strategies give inconsistent results in about 10-30%. Here coronary angiography is regarded as an accurate method for appropriate diagnosis. Ist sophisticated apparatus, cost, and invasiveness necessitate well-considered application of this procedure. Therefore, it appears important to analyze coronary angiograms in @entity1 with the referral diagnosis of "atypical" @entity662 with inconsistent noninvasive testing or impossibility to perform noninvasive assessment. @entity1 AND METHODS: We analyzed records of 1,000 consecutive @entity1 (625 @entity1 , 375 @entity1 , mean age 63.1 years), who underwent coronary angiography at our institution from January 5, 1998 to May 5, 1998. RESULTS: 49 @entity1 (17 @entity1 , 32 @entity1 ; mean age 59 years) were referred due to "atypical" @entity662 . 21 (42.9%, nine @entity1 , twelve @entity1 ) of these 49 @entity1 had normal coronary arteries at angiography. 21 (42.9%) @entity1 showed @entity453 with a diameter stenosis > 50%. In seven (14.2%) @entity1 , @entity301 with a diameter stenosis < 50% could be observed. Only five (29.4%) of the 17 @entity1 but 16 of the 32 @entity1 (50%) had @entity453 with a diameter stenosis > 50% (p < 0.01). CONCLUSIONS: In unselected @entity1 referred for coronary angiography due to "atypical" @entity662 and inconsistent noninvasive testing or impossibility to perform noninvasive assessment. 42.9% had @entity453 with a diameter stenosis > 50%. Angiographic evaluation of symptomatic @entity1 with "atypical" signs and symptoms and inconsistent noninvasive testing seems to be appropriate.
