Normal values of echocardiographic measurements. A population-based study

Abstract

Objective -To describe echocardiographic measurements and left ventricular mass in a population sample of healthy adults inhabitants of the urban region of PortoAlegre. Methods -

Geographic variation in left ventricular mass and mass index: a systematic review

“…Of the 24 cohorts that report both indexed and unindexed mass, nine still exceeded the upper ASE reference limit for LVMI ( ± 5 g m À2 ) [13][14][15]17,21,[30][31][32][33] and five had ranges up to 29 g m À2 below the upper ASE reference limit. 12,19,25,27,29 Women In women, the range of measured LVM was compatible with the ASE reference range in a greater number of studies than in men; however, LVM from eight cohorts (seven studies) still exceeded the upper ASE reference value by 11-92 g (mean 40 g) (Figure 2b). [15][16][17]22,31,32,34 A greater proportion of the range of mass exceeded the upper ASE reference limit than it did in men, with the most extreme situation being in Jordanian women, where mean LVM was above the upper ASE reference limit.…”

“…A cohort of American Blacks included in the development of the ASE Systematic review of left ventricular mass KK Poppe et al reference ranges were 25 g less, 12 another study from the US was up to 41 g less, 29 and two cohorts from Brazil were 15 g less. 27,28 These results suggest that LVM well outside the normal range is required in these populations before meeting the threshold for LVH. Indexation of mass by BSA did not remove the disparity between studies and the reference ranges (Figure 3a).…”

“…[13][14][15][16][17] The LVM from eight cohorts matched the upper ASE reference limit ( ± 10 g) 12,[18][19][20][21][22][23][24] (two studies included subjects from the cohorts used to create the reference range, 12,22 and one appears to be the study on which the twodimensional reference ranges were based 23 ), and LVM from seven cohorts was less than the upper ASE reference limit. 12,[25][26][27][28][29][30] Of those that were less than the upper ASE reference limit, three studies from Asia 25,26,30 had upper values on average 38 g less than the ASE reference limits for m-mode or two-dimensional measurements. A cohort of American Blacks included in the development of the ASE Systematic review of left ventricular mass KK Poppe et al reference ranges were 25 g less, 12 another study from the US was up to 41 g less, 29 and two cohorts from Brazil were 15 g less.…”

Women Have Higher Left Ventricular Ejection Fractions Than Men Independent of Differences in Left Ventricular Volume

“…16 A more recent study from Brazil has reported that EF is not different in men and women. 17 In contrast, most studies with larger cohorts have shown that the prevalence of systolic dysfunction (ie, low LVEF) is more than 2-fold higher in men than in women. 3,18 -22 Additionally, the mean LVEF in women has been found to be 1% to 5% higher [3][4][5][6] and to persist in multivariable models.…”

P4.53 Immediate Effects of Submaximal Effort on Pulse Wave Velocity in Patients With Marfan Syndrome

“…The eligibility criteria required patients to have either a normal aorta or minimal dilatation (less than 37 mm, as determined by an echocardiogram), with no prior dissection, a recent echocardiogram (previous 6 months), the absence of signs and symptoms of cardiac ischemia, neurological or motor disorders, and not having undergone heart surgery. Echocardiogram measures were obtained on the root of the aorta (Valsalva sinus) and were carried out by a single examiner not involved in the study, using the methodology and reference values of the Echocardiography Sector, Cardiology Division, UNIFESP, and previous studies (10,11).…”
