Previous issue date: 2013-05-06 / Funda??o de Amparo a Pesquisa do Estado de S?o Paulo / There is no data about cardiac measurements em Brazilians obtained by CMR.
This a muldisciplinary study with the objective of obtaining measurements of the
left ventricle (LV) and right ventricle (RV) diastolic diameter (Dd), systolic
diameter (Ds), diastolic volume (Dv), systolic volume (Sv), ejection fraction (EF)
and myocardial mass in Brazilians. One hundred and seven (54 men and 53
women, mean age of 43.4 ? 13.1 years) asymptomatic individuals without heart
disease were submitted to cardiac magnetic resonance (cMR) studies using
steady state free precession technique. The means and standard deviations of
the parameters of the LV and RV were respectively: LVDD = 4,8 ? 0,5 cm;
LVSD = 3,0?0,6 cm; LVDV = 128,4?29,6 ml; LVSV = 45,2?16,6 ml; LVEF =
65,5?6,3%; LV mass = 95,2?30,8.1 g; RVDD = 3,9?1,3 cm; RVSD = 2,5?0,5
cm; RVDV = 126,5?30,7 ml; RVSV = 53.6?18,4 ml; RVEF = 58.3?8,0.0% and
RV mass = 26,1?6,1 g. The masses and volumes were significantly higher in
men, except for the LVSV. The RV EF was significantly higher in women. There
was inverse correlation between RV systolic volume and with age, being more
significant in men. This study describes for the first time benchmarks for cardiac
measurements obtained by CMR among asymptomatic Brazilians individuals
without heart disease and demonstrated differences according to sex and age / N?o h? dados nacionais sobre medidas card?acas obtidas por Resson?ncia
Magn?tica Card?aca (RMc). Esse trabalho multidisciplinar teve como objetivo
obter medidas do di?metro diast?lico (Dd), di?metro sist?lico (Ds), volume
diast?lico final (VdF), volume sist?lico final (VsF), fra??o de eje??o (FE) e da
massa mioc?rdica dos ventr?culos esquerdo (VE) e direito (VD) em brasileiros.
Cento e sete (107) indiv?duos, 54 homens e 53 mulheres, com idade m?dia de
43,4 ? 13,1 anos, assintom?ticos e sem cardiopatias, foram submetidos ? RMc,
utilizando t?cnica de precess?o livre em estado de equil?brio. As m?dias e os
desvios padr?es dos par?metros do VE e VD foram respectivamente: Dd VE =
4,8 ? 0,5 cm; Ds VE = 3,0 ? 0,6 cm; VdF VE = 128,4 ? 29,6 ml; VsF VE = 45,2 ?
16,6 ml; FEVE = 65,5 ? 6,3%; massa do VE = 95,2 ? 30,8 g; Dd VD = 3,9 ? 1,3
cm; Ds VD = 2,5 ? 0,5cm; VdF VD = 126,5 ? 30,7 ml; VsF VD = 53,6 ? 18,4 ml;
FEVD = 58,3 ? 8,0% e massa do VD = 26,1 ? 6,1 g. As massas e volumes
foram significativamente maiores nos homens, exceto para o VsF do VE. A
fra??o de eje??o do VD foi significativamente maior nas mulheres. Houve
correla??o significativa e inversa do Vs do VD com o aumento da idade, sendo
mais significativo nos homens. Esse estudo descreve, pela primeira vez,
medidas card?acas obtidas pela RMc em brasileiros, as quais revelam
diferen?as de acordo com o sexo e a idade
