title: [Angiographic results of "atypical" chest pain].
abstract: OBJECTIVE
  Coronary angiography permits evaluation of coronary artery morphology and coronary pathology. It represents an accurate method of defining stenotic coronary lesions. Chest pain may be caused by coronary artery disease as well as by other cardiac and noncardiac disorders. However, sensitivity of clinical evaluation and noninvasive diagnostic assessment in detection of coronary artery disease 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 patients with the referral diagnosis of "atypical" chest pain with inconsistent noninvasive testing or impossibility to perform noninvasive assessment.
  
  
  METHODS
  We analyzed records of 1,000 consecutive patients (625 men, 375 women, mean age 63.1 years), who underwent coronary angiography at our institution from January 5, 1998 to May 5, 1998.
  
  
  RESULTS
  49 patients (17 women, 32 men; mean age 59 years) were referred due to "atypical" chest pain. 21 (42.9%, nine women, twelve men) of these 49 patients had normal coronary arteries at angiography. 21 (42.9%) patients showed coronary artery disease with a diameter stenosis > 50%. In seven (14.2%) patients, coronary sclerosis with a diameter stenosis < 50% could be observed. Only five (29.4%) of the 17 women but 16 of the 32 men (50%) had coronary artery disease with a diameter stenosis > 50% (p < 0.01).
  
  
  CONCLUSIONS
  In unselected patients referred for coronary angiography due to "atypical" chest pain and inconsistent noninvasive testing or impossibility to perform noninvasive assessment. 42.9% had coronary artery disease with a diameter stenosis > 50%. Angiographic evaluation of symptomatic patients with "atypical" signs and symptoms and inconsistent noninvasive testing seems to be appropriate.
