Resumen
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
