Abstract

The invention provides a method, medium and equipment for acquiring coronary microvascular resistance index. The coronary microvascular resistance index acquisition method includes: acquiring coronary images, the coronary images include images obtained by continuous multiple scans within a period of time after injecting a contrast agent into the target object; The start frame and end frame of the coronary image; calculate the contrast agent transit time according to the start frame and the end frame and scan parameters; obtain the aortic pressure and calculate the epicardial coronary distance according to the aortic pressure end pressure; coronary microvascular resistance index was obtained according to the epicardial coronary distal end pressure and the contrast agent transit time. The coronary microvascular resistance index acquisition method is simple to implement, does not rely on complex high-value consumables and does not require complicated operations by doctors, and is conducive to the large-scale application of IMR indicators in clinical practice.

Description

technical field [0001] The invention belongs to the field of heart and blood vessel measurement, and relates to a method for obtaining a microvascular resistance index, in particular to a method, medium and equipment for obtaining a coronary microvascular resistance index. Background technique [0002] The blood supply of the myocardium comes from the left and right coronary arteries at the root of the aorta, through coronary branches, coronary microvessels, and venules, and finally enters the right atrium through the coronary sinus or precardiac veins, and the coronary arteries in the epicardium often have vertical branches Branches medially through the myocardium, or branches perpendicularly through the myocardium in the endocardium. In recent years, with the rapid development of evidence-based medicine and interventional cardiology, the clinical significance of coronary microvascular disease has been paid more and more attention. In the process of diagnosis and treatment...
