Objective To investigate the application of best evidence for phase I cardiac rehabilitation in transcatheter aortic valve replacement（TAVR） patients into clinical practice and to evaluate its effectiveness. Methods The best evidence for phase I cardiac rehabilitation in patients with TAVR was summarized using an evidence-based care approach,and an evidence-based practice protocol was developed. The best evidence application strategy was constructed after a baseline review and analysis of barriers,and it was implemented in the cardiology department of a tertiary care hospital in Zhejiang Province from September 30 to December 31,2020. The indicators of patients before and after the application of evidence and the implementation rate of the reviewed entries were compared. Results The length of stay of patients after TAVR was shortened from 5（1,7） d at the baseline review to 3（1,6） d（P=0.016）. The percentage of cardiac function of New York Heart Association（NYHA） class I at 30 days postoperatively increased from 31.63% to 72.09%（P<0.001）,and the Katz index also improved（P=0.032）. After the application of best evidence,the rates of review indicators increased from 0~77.55% to 59.30%~100%,with a statistically significant difference（P<0.001）. Conclusion Best evidence application for phase I cardiac rehabilitation in patients undergoing TAVR can shorten patient length of stay,improve patient clinical outcomes,and standardize nurse behaviors.

Cardiovascular disease risk perception is the basis for individuals to adopt health promotion behaviors,and it is crucial to implement the primary prevention strategy of cardiovascular disease and reduce the incidence of cardiovascular disease. This paper reviews the content,characteristics and application of risk perception assessment tools for cardiovascular disease at home and abroad from the perspectives of their universality and specificity. On the basis of further defining the concept of risk perception,it is suggested to develop risk perception assessment tools for cardiovascular disease and conduct localized validation studies,providing a basis for follow-up risk communication and risk intervention by medical staff.

Objective To design a modular embedded storage device and explore its effect. Methods Quasi-experimental design was used in this study. Nurses from a cardiology department of our hospital used the modular embedded storage device to prepare supplies for nursing operation items（in an experimental group）,while nurses from a neurology department used general storage cabinets to prepare nursing products（in a control group）. Researchers tracked time spent on preparing 5 high-frequency nursing operation items in the 2 groups for 3 months. The preparation time of nursing supplies,the quantity and cost of out-of-date stock,and the satisfaction of nurses were compared between the 2 groups. Results Compared with it in the control group,the material preparation time in the experimental group was significantly shortened,and the difference was statistically significant（P<0.001）. The total satisfaction score of the experimental group was higher than that of the control group,and there were statistical differences in time-saving,comfort,convenience,safety and accuracy of picking goods（P<0.05）. There were 13 539 nursing materials expired in the control group in a year while only 3 invalid items in the experimental group,which were equivalent to 13,089 RMB and 45 RMB respectively. Conclusion The modular embedded storage device is useful to facilitate cost efficiency of the nursing supply chain,improve quality and safety of the working system,and improve nurses’ satisfaction. It is worth promoting.

To summarize the perioperative nursing of a patient with hypertrophic obstructive cardiomyopathy who underwent chemical ablation and radiofrequency ablation with Liwen operation. Nursing points include preoperative psychological nursing care,preoperative preparation,and emergency plan. Postoperative attention should be paid to volume management,hemodynamic monitoring,early implementation of stage I cardiac rehabilitation,active prevention of the occurrence of complications,and discharge guidance. After careful treatment and nursing care,the patient was discharged from the hospital on the 8th day.
