Long-Term Clinical Impact of Diabetes Mellitus In Patients With STEMI Treated by PPCI • More extensive coronary artery disease • More comorbid conditions (advanced age, renal failure, peripheral vascular disease) • Basal and post-PPCI abnormal myocardial perfusion (endothelial dysfunction, diminished coronary flow reserve, impaired ischemic pre-conditioning) • Excessive delay from symptom onset to presentation • Post PPCI high rates of restenosis and coronary lesions progression No diabetes vs. NID: Chi-Square: 2.3, p = 0.131 50 46% No diabetes vs. ID: Chi-Square: 28.1, p = 0.000 ID vs. NID: Chi-Square: 11.1, p = 0.001 40 30 27% Mortality % 20 19% 10 Insulin-dependent diabetes (ID) (n=62) Non Insulin-dependent diabetes (NID) (n=198) Non insulin-dependent diabetes (NID) (n=198) 0 No diabetes (n=1061) 0 300 600 900 1200 Time (days) Ortolani P et Al.

Conclusions • Although the evidence showing efficacy and safety of DES in PPCI patients is growing, however due to safety issues, currently indiscriminate DES use in STEMI pts with diabetes may not be recommended • BEST INDICATIONS: • - Lesions at high risk for restenosis: long-lesions, small • vessels • - High probability of viable myocardium (early onset) • - No contraindications to dual antiplatelet therapy • - After thrombo-aspiration • - After proper assessment of the vessel size (nitrates injection)

Secondary end points – Restenosis, TLR, MACE (149 pts) Angiographic restenosis, TLR, and overall MACE were significantly reduced. (Reduction in overall MACE was primarily due to the reduction in TLR – rates of cardiac death and MI were not significantly different between the two groups.) p =<0.001 p=<0.0001 p =<0.0001 % Sabatè M et al.
