RESUMOO objetivo do estudo foi determinar se a Gordura intra Abdominal medida pela Ultra-Sonografia (GAUS) em homens e mulheres tem associação com os fatores de risco cardiovascular, comparar essa medida com a circunferência abdominal e diâmetro sagital para precisar qual destes métodos é o melhor preditor de risco cardiovascular (CV), e tentar encontrar um ponto de corte para GAUS que possa definir maior risco de doença CV. Cento e noventa e um homens sadios e 231 mulheres sadias foram submetidas à medidas antropométricas, medidas de pressão arterial sistêmica e dosagens laboratoriais para colesterol, HDL, triglicerídeos e glicemia. A ultra-sonografia intra-abdominal foi realizada para medir espessura visceral. A amostra foi dividida em três grupos de acordo com a presença dos seguintes fatores de risco cardiovascular: 1) grupo de moderado risco -presença de dois ou mais dos fatores: col > 200mg/dL, HDL-colesterol < 45mg/dL, TG > 200mg/dL, Glic > 126mg/dL, PAs > 140mmHg, PAd > 90mmHg; 2) grupo de alto risco com dois ou mais dos fatores: total col > 240mg/dL, HDL-colesterol < 35mg/dL, TG > 200mg/dL +HDL < 35mg/dL, Glic > 126mg/dL, PAs > 140mmHg, PAd > 90mmHg; 3) grupo sem risco: com um ou nenhum dos fatores de risco presentes. Os resultados mostraram que a GAUS tem associação com todos os fatores de risco cardiovascular e tem melhor especificidade e acurácia que a circunferência abdominal e o diâmetro sagital. O valor de 7cm para ambos os sexos foi o ponto de corte para GAUS para predizer risco moderado; 8 e 9cm foram os pontos de cortes obtidos para GAUS para predizer alto risco CV em homens e mulheres, respectivamente. A GAUS é um método útil de determinar espessura visceral e parece ser capaz de predizer risco cardiovascular. ABSTRACTThe objective of our study was to determine if Intra Abdominal Thickness measured by Ultrasonography (IATU) has correlation with cardiovascular risk factors, and if it is a better predictor of cardiovascular risk than waist circumference and sagittal diameter. Finally we tried to find a cut off point for abdominal thickness measured by Ultrasonography to predict cardiovascular disease (CVD). One hundred ninety one healthy men and 231 healthy women were submitted to anthropometric evaluation and blood pressure measure. Blood samples were drawn for total plasma cholesterol, HDL, triglyceride and glucose determination. Intra-abdominal Ultrasonography was performed to measure abdominal thickness. The population was divided in three groups according to the presence of CVD risk factors: 1) moderately risk group (MR) with two or more of the following: total chol > 200mg/dL, HDL-cholesterol < 45mg/dL, TRIG > 200mg/dL, Glu > 126mg/DI, SBP > 140mmHg, DBP > 90mmHg; 2) high risk group (HR) with two or more of the indicated: total chol > 240mg/dl, HDLcholesterol < 35mg/dl, TRIG > 200mg/dl + HDL-cholesterol < 35mg/dl, Glu
The results suggest that insulin detemir has a greater effect on glycaemic control in subjects with poor glycaemic control using NPH; can reduce or maintain body weight in obese patients; and obtains perceptive stability for patients with unstable glycaemic control.
