Assessment on blood flow velocity at left ventricle for diastolic function diagnosis

There are many diseases related to the left ventricle due to the responsibility for pumping oxygenated blood to tissues all over the body. By using ultrasound machine with pulse wave Doppler, it could determine the potential of measurement blood flow velocity in left ventricle between the normal and abnormal reading of blood flow. This work aims to assess the velocity parameter of early diastole, E wave (Ew), end diastole, A wave (Aw), Deceleration time (Dct). E/A ratio, E/e' (medial), E/e' (lateral) for the blood flow vector at left ventricle with the assist of the Pulsed Wave (PW) for detection of blood flow circulatory in heart. All the measurement is taken using ultrasound cursor and tracer. The result is then analyzed based on a few categorizes; Body Mass Index, Smoker and Non-smoker, Exercise and Non-exercise, and Daily diet eating. This study shows that result for the blood flow of `Underweight BMI', `Normal BMI', `Non-smoker', `Regular Exercise', and `Healthy Diet' have a standard E/A value below 2.0 which are 1.85±0.06, 1.83±0.06, 1.71±0.05, 1.84±0.05, and 1.82±0.05, respectively. Therefore, the measurement of blood flow in left ventricle is very important to detect either the blood flow is normal or abnormal for the diagnosis of heart disease.
