Atrial fibrillation related stroke risk assessment method and device and storage medium

Abstract

The invention discloses an atrial fibrillation-related stroke risk assessment method and device and a storage medium, and relates to the technical field of risk assessment. The atrial fibrillation-related stroke risk assessment method comprises the following steps: acquiring a heart image of a patient; obtaining a left atrium model according to the heart image, wherein the left atrium model comprises a left atrium body, a mitral valve ring, a pulmonary vein vestibule, a left atrial appendage and the like; calculating blood flow parameters of the left atrium according to the left atrium model, wherein the blood flow parameters comprise at least one of particle residence time and blood shear rate; and evaluating a first risk index of stroke occurrence of the patient according to the blood flow parameters. The problem that the prediction capability of risk assessment in the prior art is weak is solved, and the effects of performing individualized prediction on the stroke risk according to the heart image of the patient and improving the prediction accuracy are achieved.

Description

technical field [0001] The invention relates to a tremor-related stroke risk assessment method, device and storage medium, and belongs to the technical field of risk assessment. Background technique [0002] Atrial fibrillation (abbreviated as atrial fibrillation) is the most common sustained cardiac arrhythmia. It is characterized by a fast and irregular heartbeat. As of 2010, there were estimated to be about 33.5 million patients with atrial fibrillation worldwide, with a high incidence and prevalence. The risk of ischemic stroke in patients with atrial fibrillation is extremely high, which is 4 to 5 times that of people without atrial fibrillation. How to assess stroke risk associated with AF has become an important topic. [0003] In existing schemes, the CHA2DS2-VASc score is mainly used to assess stroke risk associated with atrial fibrillation. However, the above method is based on very common clinical experience factors, such as age, hypertension and diabetes, and ...
