摘要目的：了解经皮冠状动脉介入治疗( percutaneous coronary intervention,PCI)术后患者体力活动状况,分析体力活动水平的影响因素,探究体力活动与PCI术后再狭窄的关系。方法于2015年1—12月选择哈尔滨市某三级甲等医院成功行 PCI 治疗并再次行冠状动脉造影复查的冠心病患者230例为研究对象,采用一般资料调查表、国际体力活动问卷( International physical activity questionnaire, IPAQ)为研究工具,评估PCI术后患者的体力活动状况,并分析研究对象体力活动不足的影响因素以及体力活动与PCI术后再狭窄的关系。结果 PCI术后患者体力活动处于较低水平,体力活动不足者占总人数的70.4％。居住地为城市是体力活动不足的危险因素,有配偶及术后10~12个月为体力活动不足的保护因素。再狭窄组与非再狭窄组的体力活动水平不同,差异有统计学意义( P＝0.013)。结论 PCI术后患者体力活动水平较低,低水平体力活动与术后再狭窄密切相关,城市居住、无配偶、术后6~9个月及12个月以上的患者应重点干预。

abstractsObjective To investigate the physical activity status of patients after percutaneous coronary intervention (PCI) and to determine its potential influencing factors, then analyze the relationship between physical activity and the development of restenosis in patients with PCI.Methods A cross-sectional study was conducted among 230 patients who underwent coronary angiography review again after PCI in a tertiary hospital of Harbin, to collect their information on physical activity by using general information questionnaire and international physical activity questionnaire (IPAQ). Patients′ physical activity status was accessed; the influential factors that affect the physical activity and the relation between physical activity and restenosis in patients with PCI were analyzed.Results The physical activity of patients after PCI was in low level, and patients with inadequate physical activity accounted for 70. 4%. As a residence, city is a risk factor for lack of physical activity;married status and 10-12 months after PCI are the protective factor for lack of physical activity. The level of physical activity in restenosis group was significantly different from that in the non-restenosis group (P=0.013).Conclusions The level of physical activity in patients with PCI is low, and low-level physical activity is closely related with the restenosis. Intervention measures are warranted in patients who are living in cities, unmarried, underwent PCI for 6-9 months or 12 months.
