We have examined the role of the nonlinear elastic properties of the arterial wall on the human aortic input impedance obtained at different heart rates and different pressure and flow wave shapes. Pressure and flow were taken from a computer model that pr ...
Motivated by the growing wealth of biological data and the increasing pathophysiological knowledge at different scales, spectacular progress have been made in comprehensive modeling to understand the complex nature of biological organs, such as the heart. ...
The vitamin D(3) and nicotine (VDN) model is a model of isolated systolic hypertension (ISH) due to arterial calcification raising arterial stiffness and vascular impedance similar to an aged and stiffened arterial tree. We therefore analyzed the impact of ...
Echocardiography is a widely used imaging technique to examine myocardial function in patients with known or suspected heart disease. The analysis of ventricular wall motion and deformation, in particular, allows to assess the extent of myocardial ischemia ...
The electronic miniaturization and the computer evolution (microprocessor, transputer) have contributed to the use of electric drives in a lot of applications. Because of its flexibility, the electric drive becomes an essential element to work out new conc ...
In this thesis we study ventricular-arterial coupling in rodents under the influence of arterial stiffening and myocardial infarction (MI), combination of the two considered as a novel cardiovascular research model for diseased hearts pumping against an ag ...
