528 Bachur et al. Angiographic characteristics of patients with AMI Int J Cardiovasc Sci. 2018;31(5)527-531 Original Article prophylaxis of distal embolization and prevention of complications (mechanical disorders, arrhythmias and heart failure) are necessary. 2 In the face of the advances of the last decades inmedical procedures, such as the use of the stent in angioplasty procedures, the mortality rate in cases of AMI in the world fell from 50% in the 1950s to the current 6-10% in the 1980s. 3 Percutaneous transluminal coronaryangioplasty (PTCA) or salvage coronary angioplasty is used for the immediate treatment of AMI. Percutaneous revascularization is performed without previous use of thrombolytic agents, and may or may not implant the stent. 4,5 Stents generated more predictable and long-term results in the short and long terminpercutaneous intervention scenarios thatwhen operated with balloon angioplasty. 6 The present study aimed to verify the incidence of patients diagnosed with AMI undergoing primary angioplasty, to characterize the anthropometric and angiographic variables and to identify the risk factors for CVD in this population. Methods This is a cross-sectional, observational, retrospective study in which secondary data were collected from medical records of patients diagnosed with AMI undergoing PTCA in a hospital in a city in the interior of the state of São Paulo. The majority of the interventions was carried out by the Unified Public Health System (SUS), from 2011 January to 2013 December. From the medical records were collected the variables as: anthropometric data, risk factors for ischemic heart disease: arterial hypertension (HA), diabetes mellitus (DM), dyslipidemia, smoking, sedentary lifestyle, heredity and obesity; angiographic data: location of the coronary lesion; ACTP, stent implantation and implanted type. The hemodynamic and cineangiocardiographic studywas performed through left cardiac catheterization, puncture of the right radial artery and puncture of the right femoral artery, under local anesthesia (lidocaine 2%). The cineangiocardiographic films and reports were interpreted by hemodynamicist cardiologists experienced in the area. Inclusion criteria were: patients submitted to PTCA during the first 24 hours of the diagnosis of AMI. Medical records improperly filled up were excluded. This study was approved by the research ethics committee, CAAE nº 35527714.0.0000.5495 in accordance with the Directives and Norms Regulating Researches involving Human Beings. The results will be presented in the form of absolute and relative numbers in percentages. Results The total sample comprised 437 individuals, 282males and 155 females, whose anthropometric characteristics can be observed in table 1. According to the Obesity Guidelines 2010, 7 the sample is included in the classification of pre-obese, defined by Table 1 - Anthropometric features of patients diagnosed with acute myocardial infarction (n = 437) that underwent primary coronary angioplasty at a hospital in a city in the interior of the state of São Paulo between the years 2011 to 2013 Year n Age (years) m / sd Weight (kg) m / sd Height (cm) m / sd BMI m / sd Male 2011 103 59.50 ± 10.69 80.28 ± 14.63 1.71 ± 0.07 27.40 ± 4.01 2012 104 60.03 ± 11.04 78.77 ± 16.62 1.71 ± 0.07 26.77 ± 4.96 2013 75 60.09 ± 10.86 82.16 ± 14.74 1.72 ± 0.05 27.75 ± 4.33 Female 2011 53 59.83 ± 14.32 69.8 ± 13.9 1.60 ± 0.06 27.3 ± 4.46 2012 47 64.36 ± 11.85 70 ± 14.3 1.59 ± 0.08 27.4 ± 4.94 2013 55 64.89 ± 10.48 68.60 ± 12.53 1.60 ± 0.06 26.61 ± 4.36 M: mean; sd: standard deviation.
