NORMAL VALUES FOR DIMENSIONS OF THE HEART BY ECHOCARDIOGRAPHY IN NORMAL EGYPTIAN ADULTS

Abstract

Objective: To define the normal values of cardiac dimensions and its relation to
BMI, BSA among healthy Egyptian adults living in Sohag Governorate.
Methodology: The study included 663 normal adults, ranging from 18 years to
35 years old who underwent full echocardiographic study (M- mode, two-
Dimensional echocardiography, Doppler echocardiography to exclude any
cardiac abnormalities).
Results: The IVS was 0.82 and 0.90, PWT was 0.80 and 0.90 ,LVIDD was 4.58
and 4.90, LVIDS was 2.90 and 3.12, LAD was 2.56 and 2.72, AO root was 2.38
and 2.52, RV was 2.46 and 2.56 in patients with BMI less and more than 25
respectively. The EF was 69.80 and 68.52 in BMI less than and more than 25
respectively (p=0.13). There was significant difference between BSA<1.8 and
BSA> 1.8 as regards IVS, PWT, LVIDD, LVIDS, LAD, AO root, RV and EF. The IVS
was 0.80 and 0.94, PWT was 0.80 and 0.91, LVIDD was 4.58 and 4.93, LVIDS
was 2.88 and 3.17, LAD was 2.57 and 2.72, AO root was 2.39 and 2.50, RV was
2.46 and 2.58 in patients with BSA less than 1.8 and more than 1.8 respectively.
Conclusion: We reported statistically significant difference in adult Egyptian
population for echocardiographic cardiac dimensions with respect to body mass
index and body surface area. It also varies from standards of normalcy of
populations of other countries. More studies are needed in various governments
of Egypt to get normal Egyptian cardiac dimensions in adults.
