Cardiovascular risk eutrophic young subjects: influence of corporal fat and sympathetic activity.
Introduction: There is a strong relationship between sympathetic activity and obesity to early development cardiovascular diseases. Heart rate variability analyses the balance sheet vague-sympathetic and it is an important prognostic for cardiopathies. Objective: The study measured cardiac sympathet...

Heart rate variability analyses the balance sheet vague-sympathetic and it is an important prognostic for cardiopathies. Objective: The study measured cardiac sympathetic activation in young eutrophic subjects with minor excess fat through the study of heart rate variability. Methods: Thirty-eight women were available, 21.1±1.8 years, BMI below 25 kg/m2, sedentary and divided into two groups: (1) low fat percentile (≤23%) and (2) high (>23%). The electrocardiogram was registered for 10 minutes at rest and stand. Cholesterol and triglycerides fraction was analysed. Results: HDL-c was lower in group 2 (p < 0.019) and LDL-c higher (p<0.038). Group 1 presented higher percentage of LF band in supine (p<0.13). LF band in group 2 (p<0.001) increased of supine for orthostatic position. Conclusion: Low levels of excess fat in young eutrophic women leads an increased the cardiovascular risk. Introdução: Existe forte relação entre obesidade, atividade simpática e desenvolvimento precoce das doenças cardiovasculares. A variabilidade da frequência cardíaca estuda o balanço vago-simpático, considerado importante fator prognóstico para cardiopatias. Objetivo: Medir ativação simpática cardíaca em jovens eutróficas com menor excesso de gordura pela variabilidade da frequência cardíaca. Método: Trinta e oito mulheres, com 21,1±1,8 anos, IMC abaixo de 25 kg/m2, sedentárias, divididas em dois grupos: (1) Baixo Percentil de Gordura (≤23%) e (2) Alto (>23%). Realizaram-se eletrocardiograma – registrado por 10 minutos, com as voluntárias em supino e em pé –, análises de colesterol e frações e triglicerídeos. Resultados: HDL-c foi menor no grupo 2 (p< 0,019) e LDL-c maior (p<0,038). O grupo 1 apresentou maior porcentagem da banda LF em supino (p<0.13). Houve aumento significativo da banda LF no grupo 2 (p<0,001) de supino para posição em pé. Conclusão: Baixos níveis de excesso de gordura em jovens eutróficas aumentam o risco cardiovascular. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: Portuguese refInfo: holdings: @attributes: islocal: N |
