Abstract
Cardiovascular diseases are the leading cause of death worldwide. Numerical simulation is an important way for studying cardiovascular pathology and testing cardiovascular devices. The arterial physiological characteristics of the human body vary greatly at different exercise levels. It is difficult to accurately simulate the physiological characteristics of arteries in different exercise states. This paper presents an accurate simulation method of motion states using the Proximal Policy Optimization algorithm based on a pneumatic ventricular numerical model. The results show that the proposed method can reproduce arterial pressure and flow at different motion levels with high accuracy. The simulation accuracy is more than 98%. The proposed accuracy simulation method for exercise states can be used for studying cardiovascular physiopathology and testing of cardiovascular devices.
