METHODS: A cross-sectional study was conducted between august 2002 and june 2003, including 67 breast cancer survivors. Participants were recruited from the Menopause and Breast Cancer Outpatient Facilities ( Universidade Estadual de Campinas - UNICAMP), ranging in age from 45 – 65 years, who underwent complete oncologic treatment and were not users of hormone replacement therapy, tamoxifen or aromatase inhibitors in the last six months. Evaluated risk factors for CVD like us: dyslipidemia, obesity, arterial hypertension, diabetes and smoking, and risk of CVD. The risk of CVD was estimated according to the Framingham and SCORE models. The risk of CVD was classified as low ( < 10%) , moderate ( 10 -20%) and high ( > 20%), according to Framingham function, and low ( < 3%), moderate ( ≥ 3% and < 5%) and high ( ≥ 5%), according to SCORE model. A descriptive analysis with absolute and relative frequencies, means and standard deviations (SD) was carried out. To investigate agreement between both risk models, the kappa coefficient was calculated with is respective 95% confidence interval (CI). RESULTS: The mean age of the participants was 53.2± 6.0 years and body mass index (BMI) was 27.8 ± 5.7 Kg/m². Obesity and arterial hypertension occurred in 27% and 34% of participants, respectively. Ninety percent of participants had at least one type of dyslipidemia. The most prevalent dyslipidemias were: high total cholesterol levels (≥ 200 mg/dl) in 70%, high LDL-C (≥ 130 mg/dl) in 51% and high non-HDL-C (≥ 160 mg/dl) in 48% of the participants. The risk of CVD, according to the Framingham model, was classified as low (45%), moderate (33%) and high (22%); and low (96%) and moderate (4%) according to the SCORE equation. The agreement between Framingham and SCORE models was poor (kappa coefficient of 0.122 with 95% CI: 0.013 to 0.231). CONCLUSIONS: The prevalence of risk factors for cardiovascular disease was high. Dyslipidemia was common in this cohort. The majority of participants had low to moderate cardiovascular risk. The agreement between both risk models was poor. These data indicate that the prevention of CVD in middle-aged breast cancer survivors is necessary and close attention should be focused on adequate control of serum lipid levels. KEYWORDS: breast cancer, dyslipidemia, disease cardiovascular, score of cardiovascular risk. / OBJETIVOS: Investigar a prevalência de fatores de risco de doença cardiovascular (DCV), estimar o risco cardiovascular de acordo com os modelos de Framingham e Systematic Coronary Risk Evaluation (SCORE), e avaliar a concordância entre esses dois modelos de risco em mulheres de meia-idade com câncer de mama. METODOLOGIA: Conduziu-se estudo de corte transversal entre agosto de 2002 a julho de 2003, incluindo 67 mulheres do Ambulatório de Menopausa e Ambulatório de Oncologia Mamária da Universidade Estadual de Campinas (UNICAMP), com idade entre 45-65 anos, não usuárias de terapia hormonal, tamoxifeno ou inibidores de aromatase nos últimos seis meses. Avaliou-se a prevalência de fatores de risco cardiovascular tais como: dislipidemia, diabetes, obesidade, tabagismo e hipertensão arterial e o risco de DCV. O risco de DCV foi calculado de acordo com os modelos de Framingham e SCORE. O risco de DCV foi classificado em baixo (<10%), moderado (10-20%) e alto (>20%) de acordo com a função de Framingham, e em baixo (< 3%), moderado (≥3% e < 5%) e alto (≥ 5%), segundo o modelo SCORE. Realizou-se análise descritiva dos dados com cálculo das frequências absoluta e relativa, média e desvio padrão. Para investigar a concordância entre os dois modelos de risco cadiovascular calculou-se o coeficiente kappa (k) com seu respectivo intervalo de confiança (IC) de 95%. RESULTADOS: A média de idade das participantes foi de 53,2±6,04 anos e do índice de massa corpórea (IMC) de 27,8±5,7Kg/m². A prevalência de obesidade e hipertensão foi 27% e 34%, respectivamente. Noventa porcento das participantesapresentaram pelo menos um tipo de dislipidemia. As anormalidades mais frequentes no perfil lipídico foram: colesterol total elevado (≥200 mg/dL) em 70%, alto LDL-C (≥ 130 mg/dL) em 51% e alto não-HDL-C ( (≥ 160mg/dL) em 48% das participantes. O risco de DCV, segundo o modelo de Framingham, foi classificado como baixo (45%), moderado (33%) e alto (22%), e, segundo a equação SCORE, como baixo (96%) e moderado (4%). A concordância entre os modelos Framingham e SCORE foi ruim ( kappa: 0,122; IC 95%: 0,013-0,231), considerando populações de alto risco de DCV. CONCLUSÕES: A prevalência de fatores de risco de DCV foi elevada. Dislipidemia foi comum nessa coorte. A maior parte das participantes apresentou risco baixo a moderado de DCV. A concordância entre os dois modelos de risco foi ruim. Esses dados indicam a necessidade de incluir na rotina de seguimento de mulheres com câncer de mama a avaliação do perfil lipídico e do risco de DCV, atentando-se para o adequado controle dos níveis séricos de lipídios. PALAVRAS-CHAVES: câncer de mama, dislipidemia, doença cardiovascular, modelos de risco cardiovascular.
