Abstract

The present application provides a method, device and storage medium for acquiring blood vessel evaluation parameters based on physiological parameters. The method for acquiring coronary artery evaluation parameters based on physiological parameters includes: acquiring physiological parameters; acquiring blood flow velocity v; acquiring a real-time aortic pressure waveform changing with time; The above physiological parameters were used to obtain the evaluation parameters of coronary arteries. According to blood flow velocity v, aortic pressure waveform, and physiological parameters, the application obtains coronary artery assessment parameters, and performs personalized measurement of coronary artery assessment parameters for patients with different genders and differentiated disease histories. It improves the accuracy of the measurement of coronary artery vascular assessment parameters.

Description

technical field [0001] The present invention relates to the technical field of coronary arteries, in particular to a method, a device, a coronary artery analysis system and a computer storage medium for obtaining evaluation parameters of coronary arteries based on physiological parameters. Background technique [0002] According to the statistics of the World Health Organization, cardiovascular disease has become the "number one killer" of human health. In recent years, the use of hemodynamics to analyze the physiological and pathological behavior of cardiovascular diseases has also become a very important means for the diagnosis of cardiovascular diseases. [0003] Blood flow and flow velocity are very important parameters of hemodynamics. How to measure blood flow and flow velocity accurately and conveniently has become the focus of many researchers. [0004] Coronary artery evaluation parameters include: coronary artery diastolic blood flow velocity CAIFR, and coronary a...
