Objective To describe the change trajectory of cardiac rehabilitation information needs and self-management in patients undergoing percutaneous coronary intervention （PCI） at different time points，and to explore the correlation between them. Methods A longitudinal study was conducted. From June 2021 to January 2022，186 PCI patients who met the criteria were enrolled in the cardiology ward and cardiovascular clinic of a tertiary A hospital in Jiangxi Province. General information questionnaire，the Cardiac Rehabilitation Information Needs Scale and Coronary Heart Disease Self-Management Behavior Rating Scale were employed for follow-up at 1 day before surgery，3 days after surgery，and 1，3，and 6 months after discharge to evaluate the patients’ cardiac rehabilitation information needs and self-management behavior. Results 165 cases were finally included. The total demand for cardiac rehabilitation information and the scores of each dimension in perioperative PCI patients showed an overall upward trend，but the demand for diagnosis and treatment reached the peak before surgery and within 1 month after discharge，showing a dynamic change overall. Within 6 months after discharge，the total demand for cardiac rehabilitation information，self-management and scores of each dimension of PCI patients showed an overall downward trend，but the demand for risk factor management showed an upward trend within 3 months after discharge. Within 6 months after discharge，self-management，daily life management and medical disease management of PCI patients showed a downward trend，while emotional cognitive management showed an upward trend. There was a positive correlation between them at 1 month after discharge（r=0.185，P<0.05），and a negative correlation between them at 6 months after discharge（r=-0.174，P<0.05）. Conclusion The information needs，self-management and dimensions of cardiac rehabilitation in patients with PCI change dynamically during perioperative period and within 6 months after discharge. The self-management of PCI patients was positively correlated with the total demand for cardiac rehabilitation information at 1 month after discharge，and negatively correlated at 6 months after discharge. It is suggested that medical staff should strengthen the follow-up management of patients and meet the needs of patients in all aspects of disease rehabilitation，which can further improve the self-management ability of patients and help to reduce the rate of cardiovascular events and readmission.

Objective To construct a program for elderly patients with polypharmacy after percutaneous coronary intervention，and to ensure the safety of patients’ polypharmacy throughout the process. Methods Based on evidence-based methods to retrieve domestic and foreign literature，and guided by the 4R crisis management theory，the first draft of the medication management program was formulated by the research group，and the final program was revised and established according to the experts’ opinions by Delphi method from January to July 2022. Results 15 experts participated in 2 rounds of consultations，and the effective recovery rate of questionnaire was 100%. The expert authority scores of 2 rounds were 0.90，and the importance and operability of the second round of expert opinions Kendall harmony were 0.216 and 0.289. The final program contained 4 primary indicators，7 secondary indicators and 23 tertiary indicators. Conclusion The constructed medication management program for elderly patients with polypharmacy after percutaneous coronary intervention is scientific and comprehensive，which can provide a theoretical basis and practical direction for the management of patients.

Objective To retrieve，evaluate and summarize the evidence of self-management of patients with chronic heart failure，and to provide evidence-based bases for medical staff to conduct self-management health education and standardize patients’ self-management behavior. Methods We searched UpToDate，BMJ Best Practice，Joanna Briggs Institute（JBI），National Institute for Health and Clinical Excellence（NICE），Guidelines International Network（GIN），National Guideline Clearinghouse（NGC），Scottish Intercollegiate Guidelines Network（SIGN），Cochrane Library，PubMed，SinoMed，CNKI，Wanfang Database to collect relevant clinical decisions，evidence summaries，syste-matic reviews，guidelines，expert consensuses and original articles published from the databases establishment to July 14，2022. There were 3 researchers who evaluated the quality of the literature that met the quality standards，and 2 researchers extracted and integrated evidence. Results A total of 18 pieces of literature were included，including 1 clinical decision，10 guidelines，2 systematic reviews，3 randomized controlled trials and 2 expert consensuses. Finally，39 pieces of evidence were summarized in 9 aspects，including multidisciplinary team cooperation，learning disease-related knowledge，medication management，symptom monitoring，exercise training，dietary and nutrition，lifestyle，psychological adjustment，medical treatment and follow-up. Conclusion This study summarizes the best evidence of self-management of patients with chronic heart failure，which can provide references for clinical medical staff to guide self-management of patients with chronic heart failure in a more comprehensive and scientific way.

Objective To construct a volume management program based on Information-Knowledge-Attitude-Practice（IKAP） theory and to discuss its application effect for patients with heart failure in vulnerable phase. Methods The 4 process and capacity management architecture based on IKAP theory were constructed by the expert group discussion method. Using the convenience sampling method,94 patients with heart failure from May to October 2021 were selected as the experimental group,and the same number of patients from May to October 2020 were selected as the control group,both of whom were admitted to a tertiary first-class hospital in the city of Nanchang. The experimental group received the volume management program based on IKAP theory,and the control group received the routine care of the department. Finally,we evaluated the effect of the intervention. Results 94 patients in the experimental group and 92 patients in the control group were finally collected. There were statistically significant differences in self-care ability,weight management ability,B-type natriuretic peptide level,dry body mass compliance rate and readmission rate between 2 groups after the intervention（P<0.05）. Conclusion The volume management program based on IKAP theory can improve self-care ability,weight management ability and dry body mass compliance rate of vulnerable patients with heart failure,and reduce B-type natriuretic peptide level and readmission rate in vulnerable phase.

Objective To investigate the relationship between the changes of blood pressure and palmar swelling during radial artery compression in patients with radial artery percutaneous coronary intervention (PCI). Methods The patients who underwent radial artery PCI in the coronary heart disease unit of a tertiary general hospital in Nanchang from May 2018 to December 2020 were selected as the study subjects. The general data and the related indexes of decompression were analyzed retrospectively,and the blood pressure fluctuation during radial artery compression was described. Univariate regression analysis was used to analyze the influencing factors of palmar swelling on the operative side,and the blood pressure during radial artery compression was divided into nodes. The effects of different blood pressure on operative side palm swelling were analyzed by stratification,and the corresponding range of blood pressure at the highest risk of operation side palm swelling was further analyzed by trend regression. Results A total of 788 patients with radial artery PCI were included. Based on the analysis of patients’ baseline data,it was found that history of diabetes,history of hypertension,signs of heart failure and high average systolic blood pressure during radial artery compression were the risk factors of operative palmar swelling. However,multivariate stratified analysis of risk factors showed that systolic blood pressure ≥130 mmHg during radial artery compression increased the risk of ipsilateral palm swelling in patients with diabetic history (OR=1.09,P<0.001). In patients with or without heart failure signs and hypertension history,when the systolic blood pressure during radial artery compression was more than 130 mmHg,the 2 groups increased the risk of palmar swelling on the operative side. Furthermore,trend regression analysis showed that the average systolic blood pressure during radial artery compression was between 130 and 149 mmHg. Every 10 mmHg increase in systolic blood pressure had increased the risk of palmar swelling by 3.52 times[95%CI (1.37,13.22) ]. Conclusion During the period of radial artery compression,the average systolic blood pressure of patients is 130-149 mmHg,and the risk of palmar swelling on the operative side is the highest. It is suggested that clinical nurses should comprehensively consider the changes of systolic blood pressure when formulating the prevention plan for complications of palmar swelling on the operative side.
