Objective:To understand the current situation and influencing factors of exercise intention among patients after percutaneous coronary artery stent implantation (CASI) , so as to promote patients to actively participate in exercise.Methods:Using the convenient sampling method, 165 patients with CASI who revisited in the cardiology department of a Class Ⅲ Grade A hospital in Shandong Province from May to August 2020 were selected as the research objects. General information questionnaire, Exercise Intention Scale, Exercise Self-efficacy Scale and Exercise Social Support Scale were used for investigation.Results:In this study, 165 questionnaires were distributed and 154 valid questionnaires were returned, with an effective recovery rate of 93.33%. The score of Exercise Intention Scale for 154 patients after CASI was (12.46±4.05) . The results of multiple linear regression analysis showed that age, moderate-intensity activity in the past week, classification of cardiac function, exercise self-efficacy and exercise social support were influencing factors of exercise intention among patients after CASI ( P<0.05) , which explained 47.6% of the total variation. Conclusions:The exercise intention of patients after CASI needs to be further improved and there are many factors that affect exercise intention of patients. Family members of patients and medical staff should provide more exercise support to improve their exercise self-efficacy.

Percutaneous coronary intervention (PCI) has become an important means of revascularization for patients with coronary heart disease (CHD) . Exercise therapy is the core content of cardiac rehabilitation for patients after PCI. Baduanjin, one of the traditional exercise methods of traditional Chinese medicine that spreads widely and enjoys obvious fitness effects, shows a positive impact on the rehabilitation of patients after PCI. This article reviews the effects of Baduanjin on the cardiopulmonary function, psychological status, quality of life, physical and chemical indicators, and adverse cardiovascular events in patients after PCI from different perspectives, in order to provide a reference for the practice and research of Baduanjin in the rehabilitation of patients after PCI.

Objective:To investigate the predictive value of total cholesterol / high density lipoprotein cholesterol ratio (TC/HDL) for ischemic stroke in patients with coronary heart disease (CHD) .Methods:A total of 1 983 inpatients with CHD in the Affiliated Hospital of Jining Medical University from January 1, 2017 to December 31, 2017 were selected as subjects by cluster sampling method. The clinical data were collected and followed up prospectively for 2 years.Results:During the 2-year follow-up period, 36 cases of ischemic stroke occurred in patients with CHD, and the incidence rate was 1.82% (36/1 983) . There was a curvilinear relationship between TC/HDL and ischemic stroke in male patients with CHD, and the tipping point was 3.84.When TC / HDL was less than 3.84, TC / HDL was negatively correlated with the incidence of ischemic stroke. The incidence of ischemic stroke decreased by 72% for each additional unit of TC/HDL ( P=0.049) . When TC/HDL was over 3.84, there was no correlation between TC / HDL and the incidence of ischemic stroke ( P=0.267) . There was a curvilinear relationship between TC/HDL and ischemic stroke in female patients with CHD, and the tipping point was 2.81. When TC / HDL was less than 2.81, TC / HDL was negatively correlated with the incidence of ischemic stroke. The incidence of ischemic stroke decreased by 99% for each additional unit of TC/HDL ( P=0.019) . When TC/HDL was over 2.81, there was no correlation between TC / HDL and the incidence of ischemic stroke ( P=0.110) . Conclusions:TC/HDL has different thresholds in predicting ischemic stroke in CHD patients with different genders, which has a certain clinical significance in predicting the prognosis of patients with coronary heart disease.
