Introduction:Since there are many manufacturers of cardiac troponin I assays, the true incidence of a false positive result is unknown. The authors report a case of an 18-year-old patient with previous history of recurrent myopericarditis and admitted to hospital twice again with a suspicious of myopericarditis.Conclusion:Troponin I was found to be a false positive and alkaline phosphatase interference was proved to have been the responsible for this.

Introduction: Disease prevention should begin in childhood and lifestyles are important risk determinants of cardiovascular disease. Awareness and monitoring of risk is essential in preventive strategies. Aim: To characterize cardiovascular risk and the relationships between certain variables in adolescents. Methods: In a cross-sectional study, 854 adolescent schoolchildren were surveyed, mean age 16.3±0.9 years. Data collection included questionnaires, physical examination, charts for 10-year relative risk of mortality, and biochemical assays. In the statistical analysis continuous variables were studied by the Student's t test and categorical variables by the chi-square test and Fisher's exact test, and each risk factor was entered as a dependent variable in logistic regression analysis. Results: Physical activity was insufficient in 81% of students. The daily consumption of soup, salad or vegetables, and fruit was, respectively, 37%, 39% and 21%. A minority (6%) took ≤3 and 77% took ≥5 meals a day. The prevalence of each risk factor was as follows: overweight 16%; smoking 13%; hypertension 11%; impaired glucose metabolism 9%; hypertriglyceridemia 9%; and hypercholesterolemia 5%. Out-of-school physical activity, hypertension and overweight were more prevalent in males (p<0.001). Females had higher levels of cholesterol (p<0.005) and triglycerides (p<0.001). A quarter of the adolescents had a relative risk score for 10-year cardiovascular mortality of ≥2. Overweight showed a positive association with blood pressure, changes in glucose metabolism and triglycerides, and a negative association with number of daily meals. * Corresponding author.

A colheita de dados incluiu questionários, exame físico, tabela do risco relativo da mortalidade cardiovascular a dez anos, doseamentos bioquímicos. A análise estatística incide sobre variáveis contínuas e categoriais e fatores de risco como variáveis dependentes (regressão logística). Resultados: Atividade física insuficiente 81%. Consumo diário de sopa, salada/legumes e frutas caracterizou 37, 39 e 21% dos alunos. Uma minoria (6%) fazia diariamente ≤3 refeições e 77% ≥5 refeições. Prevalência dos fatores de risco: excesso de peso 16%; tabagismo 13%; hipertensão arterial 11%; anomalias do metabolismo da glicose 9%; hipertrigliceridemia 9%; hipercolesterolemia 5%.
