Background: Acute ischemic cardiovascular and cerebrovascular diseases are a kind of diseases with high incidence, rapid progression, poor prognosis and high mortality and disability rate of the circulatory system, mainly including acute myocardial infarction, acute ischemic stroke and acute limb ischemia, which place a heavy burden on individuals, families and society due to their severe prognosis and high medical costs. At present, the diagnosis and treatment of ischemic cardiovascular and cerebrovascular diseases mainly focus on single organ diagnosis and treatment of target organs, lacking of indicators to comprehensively evaluate the body's pathophysiology. As ischemic disease of the circulatory system, ischemic cardiovascular and cerebrovascular diseases have common pathophysiological basis such as ischemia, hypoxia and inflammation. These common pathophysiological basis suggests that different acute ischemic cardiovascular and cerebrovascular diseases can be monitored and evaluated from an integrated perspective, it suggests the possibility of comprehensive diagnosis, evaluation and treatment guidance. At present, the "circulatory integration" therapy represented by the combined treatment of heart and brain has achieved certain results, but there is no corresponding evaluation system to provide accurate guidance. Therefore, with the concept of "circulation integration", it is an urgent problem to find the common indicators of the circulation system and construct the hierarchical diagnosis and subsequent evaluation system of acute cardiovascular and cerebrovascular integration. The development of efficient and comprehensive stratified diagnosis and prognosis evaluation system is of great significance in clinical, market and social aspects. At the early stage of the efforts our team, it was found that Dan Shen Su-(±)-3, 4-dihydroxyphenylacetic acid (DSS) could be detected in the plasma and urine of patients with acute myocardial infarction and ischemic stroke through metabolomics. It has been proved that it can be generated by the transformation of dihydroxyphenylalanine by proteus mirabilis, and its structure is consistent with the water-soluble component of salvia miltiorrhiza, which is related to the body's states of ischemia, hypoxia and inflammation. The findings provide a material basis for the "circulatory integration" assessment of acute ischemic cardiovascular and cerebrovascular diseases. Objectives: This study aims at acute ischemic cardiovascular and cerebrovascular diseases, with the concept of "circulatory integration", to build a hierarchical diagnosis and prognosis evaluation system with DSS as the core, in order to improve the diagnosis rate and cure rate, improve the prognosis and reduce mortality of ischemic cardiovascular diseases. Methods: The project included 500 patients with acute myocardial infarction, 300 patients with acute ischemic stroke, 300 patients with acute lower limb ischemia, and 200 healthy controls in the Affiliated Hospital of Xi'an Jiaotong University, Xi'an, Shaanxi, Peoples R China. Plasma and urine were collected during the disease process. Various relevant clinical indicators including DSS level were included, COX model was applied to analyze the influence of multiple factors on the prognosis of the above diseases, and the indicators were screened and the integrated stratified diagnosis and prognosis evaluation system of acute ischemic cardio-cerebrovascular system with DSS as the core were established. The newly established integrated stratified diagnosis and prognosis assessment system was used to evaluate 200 patients with each of the three diseases, and the sensitivity and specificity of the new assessment system were tested. And a simple, rapid and accurate method for detecting DSS was developed.

Incidence of disease recurrence
Incidence of disease recurrence，including acute myocardial infarction, ischemic stroke and acute lower limb ischemia.
12 months after admission
Incidence of cardiac death
All deaths were considered to have been from cardiac causes unless a explicit noncardiac cause could be documented.
12 months after admission
Incidence of all-cause death
All deaths were taken into account unless there is a definite cause of accidental death.
12 months after admission
700 patients with AMI;several demographics, clinical and analytical parameters were collected, and peripheral blood and morning urine were collected from the patients and the volunteers after admission on the first, second, third and seventh days for DSS detection.Observe the dynamic changes of DSS level in acute ischemic cardiovascular disease of different severity. Adverse events (survival outcome) were observed and recorded in the hospital and at 1, 3, 6, and 12 months after discharge. Major adverse events mainly include disease recurrence, cardiac death and all-cause death. The newly established "circulatory integration" diagnosis and treatment evaluation system of acute ischemic cardiovascular with DSS as the core was used to predict the prognosis of patients with acute ischemic cardiovascular diseases.
