Coronary heart disease is the leading cause of death in the United States and many developed countries. Percutaneous coronary intervention (PCI) is an important means to treat coronary heart disease. However, PCI can not eliminate the risk factors of coronary heart disease. As an important auxiliary means of PCI, cardiac rehabilitation can significantly slow down the progress of atherosclerosis, reduce cardiovascular events, improve patients′ exercise tolerance and the quality of life of patients. It have been developing vigorously in developed countries and achieved remarkable results. This paper will review the effects of cardiac exercise rehabilitation and the research on cardiac exercise rehabilitation in different clinical stages.

This study mainly introduces the exploration of the construction and management of multi-level medical training platform in clinical skills center of the Affiliated Hospital of Yangzhou University. Through the construction of a multi-level clinical skills training platform, a reasonable hierarchical training program is formulated by taking the clinical basic skills training platform and the clinical specialist skills training platform as the basic core teaching content. This program adopts various ways to improve the teaching quality, effectively promote students' ability of clinical practice step by step, meet the needs of different levels of medical personnel in different stages, scientifically and effectively cultivate the high-quality medical personals, and give full play to the role of hospital clinical skills center in medical education, which lays a good foundation for the continuous improvement of teaching quality in hospitals.

Objective To investigate the effect of dual track interactive nursing intervention in the management of refractory hypertension.Methods A total of 84 patients with refractory hypertension were randomly divided into control group andexperimental group,with 42 cases in each group.Patients in the control group received conventional therapy and nursing intervention,while patients in the experimental group received dual tract interactive nursing intervention.Medication compliance,blood pressure,and score of self management between the two groups were observed.Results The experimental group had higher medication compliance,and better control of systolic and diastolic blood pressure,and higher score of self management than that in the control group (P ＜0.05).Conclusion Dual tract interactive nursing intervention model is effective in improving the medication compliance of refractory hypertension patients,helping the patients to control blood pressure.
