The high BMI ratio is a correlated risk factor for chronic diseases and a high mortality rate. Analyzing risk factors for CVD of the sample, we observed that HTN is the predominant factor in both sexes, followed by smoking for men and dyslipidemia for women, as shown in table 2. When considering the coronary arteries in the AMI, the anterior descending artery (ADA) is the most prominent, and its revascularization a survival factor. 8 The descriptions of the affected arteries are shown in table 3. The stent implantation has a marked predominance when compared to the use of the balloon, it has being Table 3 - Arteries affected by acute myocardial infarction in diagnosed patients (n = 437), submitted to primary coronary angioplasty, in a hospital in a city in the interior of the state of São Paulo, between the years 2011 to 2013 Artery 2011 2012 2013 Male n% Female n% Male n% Female n% Male n% Female n% ADA 46 44.66% 25 47.16% 40 41.60% 19 40.42% 33 44% 20 36.36% RCA 39 37.86% 21 39.62% 39 37.50% 19 40.42% 27 36% 24 43.63% CA 13 12.62% 5 5.43% 16 15.38% 7 14.89% 10 13.30% 10 13.33% DA 5 4.85% 0 0% 7 6.73% 1 2.12% 0 0% 1 18.18% MA 0 0% 2 3.77% 2 1.92% 1 2.12% 5 6.66% 0 0% ADA: anterior descending artery; RCA: right coronary artery; CA: circumflex artery; DA: diagonal artery; MA: marginal artery. mainly used in 96.62% of the angioplasties performed in 2011, 91.26% in 2012 and 92.3% in 2013. There was a rise in the use of the pharmacological stent, increasing from 3.88% in 2011, to 4.52% in 2012 and to 10.90% in 2013, becoming more and more a priority in hospitals that perform PTCA. Important to be considered is the high cost of the pharmacological stent, since in the sample there is a predominance of patients using SUS, being 73.17% in 2011, 82.25% in 2012 and 89.87% in 2013. Regarding the use of private health, is 27.76% in 2011, 17.87% in 2012 and 10.11% in 2013.
