Distribution of coronary artery disease in acute coronary syndrome patients with diabetes mellitus

Results Leading diagnosis at admission in ACS patients with DM and without DM was STEMI (53%, 55% respectfully). According to the ACC/AHA classification of coronary lesions patients with DM had 56% of type B lesion, 41% of type C lesion and 3% of type A lesion. In our study, the largest number of significant stenosis was observed in the proximal and middle segment of LAD: 74% of patients with DM and 60% in patients without DM. In patients with DM single-vessel CAD was observed in 26%, twovessel in 41% and three-vessel in 32%, whereas in patients without DM, 52% single-vessel CAD, 30% two-vessel and 18 % three-vessel CAD. Conclusion Most of the studies showed that patients with DM are more likely to have diffuse distribution of CAD. Results of studies about the association of DM with the location of the lesion in CAD is also contradictory, in some studies was observed a higher incidence of proximal, and in other distal lesions. In our study, mostly affected was LAD, usually its proximal and middle segment. Also, RCA and ACx were more affected in the proximal and middle segment. The study found a higher prevalence of type C lesions and a higher prevalence of three-vessel CAD in patients with DM which confirms previous findings that patients with DM usually have diffuse CAD.
