OBJECTIVES: To investigate the prevalence of risk factors for cardiovascular disease (CVD), estimate the cardiovascular risk, acoording to the Framingham and Systematic Coronary Risk Evaluation (SCORE) risk models, and evaluate the agreement between both risk models in middleaged breast cancer survivors (BCS). 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.
