Prediction method and system for survival rate of acute myocardial infarction patients within 5 years

Abstract

The invention relates to a prediction method and system for the survival rate of an acute myocardial infarction patient within 5 years. The method comprises the steps: acquiring clinical data of the acute myocardial infarction patient during hospital admission; establishing a prediction model according to the clinical data, establishing a column diagram of the survival rate within 5 years, calculating a total risk score, and then calculating a prediction value of the survival rate of the patient within 5 years; and outputting a predicted value of the survival outcome occurrence probability ofthe patient within 5 years. External verification proves that the method is suitable for Chinese people, statistical analysis is carried out by combining various potential risk factors influencing poor prognosis such as hospitalization baseline vital signs of acute myocardial infarction patients, operations and drug intervention, laboratory examination and imaging examination, factors related to the survival rate within 5 years are screened out, a prediction system for the survival rate of the acute myocardial infarction patient within 5 years is established, and a risk quantitative value is provided for clinicians to predict the survival rate of the acute myocardial infarction patient within 5 years more comprehensively and accurately.

Description

technical field [0001] The present invention relates to the technical field of clinical medicine, more specifically, to a method and system for predicting the 5-year survival rate of patients with acute myocardial infarction. Background technique [0002] In recent decades, with economic and social development and population aging, cardiovascular disease has gradually become one of the most important factors threatening human health around the world. Acute myocardial infarction (AMI) is the most serious form of coronary artery disease, manifested as myocardial cell necrosis caused by acute and persistent coronary ischemia and hypoxia. It causes more than 2 million people to survive every year in the United States, and more than 4 million people to survive every year in Europe and northern Asia. It is the main cause of survival worldwide. In recent decades, with the establishment of chest pain centers, more patients have been treated in a timely manner, and with changes in t...

Problems solved by technology

[0005] Different scoring systems have different application values. The GRACE score, KAMIR score, and Gensini score are mainly used to analyze the short-term prognosis of patients with acute coronary syndrome, and there are few studies on the long-term prognosis of patients with acute coronary syndrome.
