Aim. To investigate factors associated with intact coronary arteries identification in two categories of patients — with suspected coronary artery disease (CAD) and after previous myocardial infarction (MI). Material and methods. 457 case records of patients who were in clinic of Kemerovo Cardiology Center for the period from April 1 to May 31 2014 were retrospectively analyzed. All patients underwent routine coronarography. Based on the indications for coronarography 2 groups were formed: Group 1 — patients with suspected coronary artery disease (n=248), group 2 — patients with history of myocardial infarction (n=209). Results. It was noted that absence of occlusive and stenotic changes and non-significant coronary lesion (stenosis <60%) prevailed among patients with suspected coronary artery disease (42.7 and 17.3%) in relation to patients with MI history — 12.9 and 8.1%, respectively (p<0.001 and p=0.004). More severe coronary disorders (stenosis ≥70%) were significantly more often seen in patients with previous myocardial infarction — 76.6 and 36.3% (p<0.001). A typical clinical picture of angina was diagnosed with equal frequency in both groups — 59.3 and 54.6% (p=0.309), while atypical clinical angina and cardialgia prevailed in group of  suspected coronary artery disease (p=0.002 and p<0.001). Pre-test probability of coronary artery disease was 68 and 77% (p=0.007). Atypical angina was independent predictor of intact coronary arteries in patients with suspected coronary artery disease. At the same time, frequency of coronary lesion absence decreased in males and in older age patients (p<0.001). Atypical angina was the factor associated with intact coronary arteries in patients with history of myocardial infarction. Male gender conversely increased the likelihood of atherosclerotic coronary lesion. Conclusion. According to elective coronary angiography coronary lesion was observed in 42.7% of patients with suspected coronary artery disease and in 12.9% of patients with a history of MI. The probability of intact coronary arteries was associated with atypical angina clinical picture. Male gender and advanced age were independent predictors of atherosclerotic coronary lesion.
