“…Em um estudo retrospectivo que objetivou avaliar as diferenças entre homens e mulheres após IAM, o DM foi o fator de risco menos prevalente, presente em cerca de 10% dos pacientes, de ambos os sexos (17) . Porém, em um outro estudo retrospectivo realizado na Bahia com população de características semelhantes, o DM foi mais freqüente nos grupos biarterial e multiarterial, 63% e 36% respectivamente (18) .…”

Our purpose is to characterize the profile of patients with Acute Coronary Syndrome (ACS) assisted in an emergency service in Porto Alegre. The characterization of the profiles focus on risk factors. This prevalence study was carried out from August, 2007 to February 2008. To collect the data, we developed a questionnaire, checked bedside assessment and measured anthropometric evaluation. 152 patients had their ACS evaluated, of which 63.8% were males, with an average age of 61 +/- 10.26 years. 50.7% had acute myocardial infarction non-ST elevation, 14.5% acute myocardial infarction with-ST elevation, and 34.9% unstable Angina. Risk factors were sedentariness (86.8%); overweightness and obesity (77%); systemic arterial hypertension (75.7%); family history (56.6%); stress (52.6%); dyslipidemia (44.7%); diabetes mellitus (40.1%); tobacco smoking (39.5%); and alcohol consumption (14.4%). A high prevalence of risk factors for ACS was verified, indicating a necessity of health education programs to reduce morbimortality.

“…[29] These results confirm the importance of hypertension as a risk factor for the occurrence of ACS. [1] In earlier descriptive and retrospective studies, in Brazil south [1] such as in Bahia, [22] DM was present in about 40% of patients. In the present study, DM was recorded at 37.8% (p = 0.001) of patients going against the expectations.…”

Background: Ischemic heart disease is an important death cause in Brazil. The Acute Coronary Syndrome is a subset of signs and symptoms which represents an acute complication of ischemic heart disease. Many of these patients have common risk factors, including renal dysfunction. The analysis of the importance of this commitment in the event of outcomes is still little explored in our midst. Objective: To study the associantion betweent renal dysfunction and the occurrence of deaths in patients with Acute Coronary Syndrome, Methods: This is a analytical study, with patients admitted to the Coronary Care Unit of a Tertiary Hospital (Salvador / BA) diagnosed with acute coronary syndrome, in the period from 2011 to 2014. The patients were divided into three groups according to renal function and two groups according to clinical diagnosis. Results: We identified six hundred seventy-four (n = 674) individuals. Mean age was 69.6 ± 12.4 years and 50.7% (n = 342) were male. Regarding the clinical diagnosis, 49% of patients (n = 331) were diagnosed with Unstable Angina and 50.9% (n = 342) with Acute Myocardial Infarction. The average value of creatinine clearence rate was 63.2 ± 29.3 ml / min (p = 0.001). Conclusion: The severe renal dysfucntion is an important prognostic factor for development of coronary artery disease and was associated with bad prognosis of patients with ACS. The variables DM, hypertension and dyslipidemia were often associated in theses patients.

“…In 2016, 1,131 coronary angiographies were performed in the institution in patients with ACS. Considering the expected frequency of 83.6% for ≥50% stenosis, 16 the minimum sample size calculated was 178 patients, with 95%CI and sample error of 5%. To make sure the sample size was enough to ensure good accuracy, in the second analysis, assuming an area under the Receiver Operating Characteristic (ROC) curve of 0.65, 144 patients (103 without complex disease and 41 with complex disease) would be required to provide a statistical power of 80% and reject the null hypothesis of an area of 0.50, with an alpha of 0.05.…”

Background: Although much is known about the prognostic value of the GRACE risk score, there are few studies investigating how it relates with the angiographic complexity of coronary artery disease. For this reason, in this study, we aimed to assess the predictive capacity of the GRACE score in acute coronary syndrome in respect to the angiographic complexity based on the SYNTAX score. Methods: A cross-sectional study of patients with acute coronary syndrome undergoing coronary angiography during hospitalization, with at least one ≥50% stenotic lesion in vessels ≥1.5mm in diameter. Complex coronary artery disease was defined as SYNTAX ≥23. Results: This study investigated 183 patients. A positive correlation was observed between the GRACE and the SYNTAX scores (p=0.005), however the association was weak (r=0.20). The GRACE score showed discriminatory capacity between patients with and without complex coronary artery disease, however the relevance was low, with an area under the ROC curve of 0.59 (95%CI: 0.51-0.67; p=0.042). Conclusion:The GRACE risk score is not a sufficiently accurate predictor of angiographic complexity in acute coronary syndrome.
