A Study of Cardiovascular Hemodynamics in Obese Patients Assessed by Echocardiography and Nuclear Scintigraphic Tests and Using a Mathematical Model

We studied hemodynamics characteristics at the heart level for a lot of 15 obese patients. We investigated echocardiographic and multigated radionuclide parameters correlating with the body mass index (BMI) or left ventricular ejection fraction (LVEF). Furthermore, the linear relationship obtained by plotting end-systolic volume (ESV) against end-diastolic volume (EDV) can be more useful than the relation between stroke volume (SV) and EDV (Starling curve) in the analysis of a multitude of different ventricles. In order to assess left ventricular diastolic function, besides of the Doppler transmitral velocity curve, we used a mathematical model of mitral flow; the model equations were solved using Matlab-Simulink.
