About

Mainly studying the correlation between the abundance of Prevotella copri （P.copri） in the gut microbiome and the progression of clinical coronary atherosclerotic heart disease（CAD） patients, and confirming that an increase in P.copri abundance will accelerate the occurrence and development of CAD disease, accompanied by an increase in serum Branched chain amino acid（BCAA）, lipopolysaccharide（LPS）, and serotonin; For people who mainly consume a high carbon water diet, blood sugar is a stronger risk factor for AS compared to blood lipids; Explore the KAP status（Study composes of Knowledge, attitude, and practice） of coronary heart disease patients and their caregivers regarding coronary heart disease and diet, and investigate whether the popularization of science after KAP investigation can change the treatment effect of patients.

Full description

Confirming the progression of coronary heart disease in patients and the proportion of P.copri in the gut microbiome; Confirming that due to the increased abundance of P.copri, factors related to blood glucose metabolism disorders are more associated with the progression of CAD disease compared to lipid factors; Confirming that P.copri induces insulin resistance and inflammation in the body while altering intestinal permeability through the synthesis of BCAA, LPS, and serotonin;; Through controlled experiments conducted at our center, investigators effectively popularized disease science to patients and their caregivers, promoted their participation in disease treatment, and confirmed that the KAP survey method can optimize patient treatment effectiveness, improve doctor-patient relationships, and enhance patient hospitalization experience. Through this research project, investigators explore the application of KAP research in the form of a questionnaire in this discipline. Through KAP research, investigators aim to popularize knowledge about dietary patterns and coronary heart disease among multi center coronary heart disease patients and their caregivers. investigators also investigate the "knowledge", "belief", and "behavior" of current coronary heart disease patients and their caregivers regarding coronary heart disease diagnosis and treatment knowledge, and conduct a knowledge lecture, Establish a new model for mastering, attitudes, and actions related to the diagnosis and treatment of coronary heart disease among patients and their accompanying caregivers through data push and other forms, while also providing theoretical and practical basis for subsequent related research. Through this project, investigators will discuss the feasibility of KAP survey in increasing patients' subjective initiative, improving doctor-patient relationships, and promoting the effectiveness of patient treatment. investigators will also discuss its promotion and inclusion in routine diagnostic and treatment methods.

---

200 participants in 4 patient groups

Coronary heart disease group

No Intervention group

Description:

16SrDNA sequencing and ELISA test were carried out for patients over 50 years old who reported coronary atherosclerosis after coronary angiography or coronary angiography with CT examination to detect the abundance of Prevotella in their intestines, the concentration of 5-hydroxytryptamine, branched chain amino acids and lipopolysaccharide in their blood

Non coronary heart disease group

No Intervention group

Description:

For patients over 50 years old who reported no coronary atherosclerosis after coronary angiography or CTA examination, 16SrDNA sequencing and ELISA tests were carried out to detect the abundance of Prevotella in the intestinal tract, the concentration of 5-hydroxytryptamine, branched chain amino acids and lipopolysaccharide in the blood

KAP group

Experimental group

Description:

Conduct a survey on the relationship between coronary heart disease and dietary patterns among hospitalized patients in the form of KAP Popular Science Research. After the survey, conduct scientific popularization of relevant knowledge, conduct a satisfaction questionnaire survey after surgery, and collect data on preoperative and postoperative examinations and laboratory tests

Non KAP group

Sham Comparator group

Description:
