RESUMO:

Cardiac measures used as reference in CMR were obtained mainly from studies done in north-American and European populations. Objective: The objective of this study was to obtain 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 and also to assess differences between sex and age groups. Methods: 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. Results: The means and standard deviations of the parameters of the LV and RV were respectively: LVDD = 47 + / - 0.5 mm; LVSD = 30±0.5 mm; LVDV = 128.4±26 ml; LVSV = 45.1±16 ml; LVEF = 65.5±6.6%; LV mass = 95.1±27.1 g; RVDD = 38±1.1 mm; RVSD = 25±0.5 mm; RVDV = 126.4±30.8 ml; RVSV = 53.5±18.9 ml; RVEF = 58.3±7.6% and RV mass = 26.1±7.6 g. The masses and volumes were higher in men (p <0.01), except for the LVSV. The EF were higher in women and in higher age groups (p <0.01). The oldest age group had the smallest diameters and volumes (p <0.01), except for the LVSD and LVSV. Conclusion: This study describes for the first time benchmarks for cardiac measurements obtained by CMR among Brazilians and demonstrated differences according to age and sex.
