Smoking was a factor of great disparity between the two care networks (34% vs 9.3%; p < 0.001). Most patients presented the association of 2 risk factors in both services (35.1% vs 40.7%, p = 0.534) (Table 2). When the characteristics related to the pathological history of both groups were evaluated, a prevalence of factors related to the patients attended by the private service was observed, with them being a previous history of AMI (7.1% vs 16.1%, p = 0.002), and previous angioplasty (4.9% vs 10.2%; p = 0.026), and prior coronary artery bypass grafting (0.8% vs 5.1%, p < 0.001). The prevalence of family history of previous coronary artery disease (29.4% vs 44.1%, p = 0.002) and peripheral vascular disease (5.3% vs 15.3%; p<0.001) (Table 2) are also observed for the patients of the private service. Coronary reperfusion During STEMI, there was a significant disparity between the results obtained by all patients attended at SUS and all those who sought private care regarding the use of PA. For the former, the reperfusion rate was 45.3% while for the latter it was 79.7% (p < 0.001). In both services, the use of conventional and pharmacological stents was analyzed, and in this aspect an important discrepancy was also observed, since there was a predominance of the use of bare metal stents in SUS (89.5%, p < 0.001), and DES in the private network (82.4%, p < 0.001) (Table 3). Coronary reperfusion in diabetic patients In view of the recommendation of guidelines 1,3 for the use of DES in diabetics, with level of evidence A and indication class II, these patients were grouped in a special subgroup to assess if the recommendations for stent placement are being followed during coronary angioplasty. A total of 199 diabetic patients were seen in the public service; of these, 47.7% had access to PA and, in most interventions (91.3%), bare metal stents were used, while only 8.7% used DES (p < 0.001). In the private service, 42 diabetics were attended; of these, 78.6% had access to primary PCI, with placement of drug‑eluting 566
