Abstract

The invention provides an aortic pressure waveform image generation method and a storage medium. The aortic pressure waveform image generation method comprises the steps of obtaining aortic pressure Pa data; extracting a stable pressure waveform according to the aortic pressure Pa; setting a display interval of the stable pressure waveform; setting a data range of the stable pressure waveform; andgenerating an aortic pressure waveform image according to the display interval, the data range and the stable pressure waveform. According to the method, the aortic pressure waveform image can be rapidly, accurately and automatically generated from the original aortic pressure data by means of the heartbeat cycle and the pressure transmission rate.

Description

technical field [0001] The invention relates to the technical field of coronary artery medicine, in particular to a method for generating an aortic pressure waveform image and a storage medium. Background technique [0002] The deposition of lipids and sugars in human blood on the blood vessel wall will form plaques on the blood vessel wall, which in turn will lead to vascular stenosis; especially the vascular stenosis near the coronary artery of the heart will lead to insufficient blood supply to the myocardium and induce coronary heart disease , angina pectoris and other diseases pose a serious threat to human health. According to statistics, there are about 11 million patients with coronary heart disease in my country, and the number of patients treated with cardiovascular interventional surgery is increasing by more than 10% every year. [0003] Conventional medical detection methods such as coronary angiography (CAG) and computed tomography (CT) can show the severity o...
