Refference Normal Values Of Morphologic And Functional 2d-echocardiographic Parameters Evaluated In A Group Of Young Healt Adults Authors: Al.Andritoiu, N.Gavrila Military hospital CRAIOVA Romania

Introduction Despite an over two decades experience in echocardiography, Romanian cardiology do not knows some reference studies involving health people and also differing by age category Romanian military cardiology also, needs some modern studies based by evaluation with an actual US- technique of the principal morphologic and functional parameters, specific to the young adult age

Objectives determination by ultrasonographic investigation of principal morphologic and functional cardiac parameters, in a group of young adults without heart diseases need of reference standard values for our own echo- laboratory and also in Romanian cardiology literature

Method SIEMENS SONOLINE Versa Plus-echocardiograph 2.5 MHz- electronic ultrasound probe Standard approach - left parasternal LAX- view - apical - 4 C and apical 5- C views the pacient positioned in left- lateral decubitus at an angle of 90 degrees the measurements were made in 2D-Echo ASE recommendations were respected Spectral Doppler (PWD) with theta angle correction

The Study Group N = 80 Males Mean age (yr.)…….. 21.35+/-1.76 (18 - 29) Height (cm)……….….175+/-6.35 (163 - 189) Weight (kg)…………..72+/-13.75 ( 53 - 117) BS Area (m2)...…..…1.86+/- 0.17 (1.56 - 2.41) BMI (kg/m2)………..22.66+/- 3.68 ( 21 - 37 )

Statistics The results were represented as: - Mean value - Standard deviation - Maximal value - Minimal value The correlations were determined by Pearson equation

Results 1. Morphologic Parameters Aor Aov IVSd PWd LVd LVs 0.85 LA RA 3.1 2. 2 2.62 3.28 Mean 1.94 2.85 0.84 Sd 0.17 0.26 0.06 0.06 0.36 0.38 0.33 0.42 0.32 Max 2.17 2.9 1 1 5.5 4.2 3 3.9 3.8 Min 1.6 2.1 0.7 0.7 3.4 2.5 1.6 1.9 2.8 Results are expressed in cm. 4.45 RD

Results 2. Lv Mass Indicators LV Mass(g) =1.04((LVd+IVSd+PWd)3-LVd)3-14 (Devereux) Mean LV mass = 134 +/- 27,4 g Max. LV mass = 235 g Min. LV mass = 70 g LV Mass Index = LV Mass (g) / BSA(m2) Mean LVMIx = 71,54+/-14.2 g/m2 Max. LVMIx = 110 g/m2 Min. LVMIx = 45 g/m2

Results 3. LV Diastolic Function Pick E (m/s) Pick A (m/s) E/A IVRT (ms) EF-S (mm/s) Mean 0.91 0.51 1.91 64.86 121.4 Sd 0.17 0.13 0.36 9.04 19.6 Max. 1.37 0.79 2.6 90 165 Min. 0.56 0.25 1.13 50 75

Results 4. LV Systolic Function (Evaluation by PWD in LV Ejection Tract) Vmx (m/s) ACC (m/s) AT (ms) VTI (cm) LVET (ms) Mean 1.11 15.81 75.14 19.4 Sd 0.19 2.02 8.22 3.7 28.36 Max. 1. 8 21.5 90 28 300 Min. 0. 8 12.12 50 14.5 180 267.5

Statistical Corelations BSA vs LV Mass ; r = 0.51 (p<0.01) BMI vs LV Mass ; r = 0.42 (p<0.01)

Conclusions The morphologic parameters found in our study group are similar with the literature data; they are related with somatic indicators of the subjects which were studied In young adults, LV systolic and diastolic functional parameters appear with high amplitudes in comparison with the values reported in health adults and olds; these data are useful in a correct estimation of LV hemodynamic performance
