Abstract
ABSTRACT
Background
Healthy cardiac function is evaluated by echocardiography in the non-invasive
cardiology department. Cardiac functional and structural evaluation is assessed by
cardiologists based on a physiologically defined normal range. We want to compute
the physiological value of variables in the healthy population.
Objective
To compute and compare the recorded echocardiographic parameters among
apparently healthy patients.
Method
This is a retrospective study and a total of 544 subjects whose standard reference
range was within the normal limit are included for computational study. 268 males
(52.8%) and 240 females (47.2%) were studied for the size of the aortic root, size of
the left atrium, left ventricular internal diameter during diastole (LVIDd) and systole
(LVIDs), interventricular septum during diastole and systole (IVSd and IVSs), left
ventricular posterior wall during diastole (LVPWd) and systole (LVPWs) and ejection
fraction (EF).
Result
Ejection fraction (EF) is not significantly different (p=0.14) between genders,
Mean±SD; 70.45±6.7 for females and Mean±SD; 68.34±7.18 for males. The mean
age of examined female patients is Mean±SD; 36.88±12.6 which is not significantly
different with male patients age Mean±SD; 38.28±12.5. Males have larger left
ventricular internal diameter in diastole, Mean±SD; 43.90±6.4 than females
Mean±SD; 41.37±8.08. Ejection fraction for females is Mean±SD; 70.45±6.7, for
males is Mean±SD; 68.34±7.18 with p=0.14.
Conclusion
Absolute echocardiographic measurements vary physiologically between apparently
healthy genders yet the ejection fraction is not significantly different between both
the genders in the examined Nepali population.
