Modelling blood pressure in stenosed coronary arteries

Abstract

In this paper a 1D model is presented for the simulation of blood ow in stenosed coronary arteries. The model was developed by implementing a special boundary counditions in a previously published arterial blood ow model. The stenosis as well as the arterioles were modelled as linear resistances. Using patient-specific parameters, blood ow can be calculated for different inlet ow rates. The model was used to simulate blood pressure waveforms of 5 patients diagnosed with coronary stenosis. Simulation results show good agreement with measurement data.
