Abstract P454: The Predictors of Non-adherence of Regular Physical Activity After Coronary Revascularization

Abstract

Background: Coronary heart disease the leading cause of mortality worldwide and regular physical activity is a comprehensive management strategy for these patients. We investigated the parameters that influence regular physical activity in patients with a history of coronary revascularization. Methods: We included outpatients who had a history of coronary revascularization at least 6 months prior to enrollment. A questionnaire was filled out with each patient to collect the data of engagement in regular physical activity, demographics, clinical characteristics, and dietary adherence. Results: We enrolled 202 consecutive outpatients (age 61.3±11.2 years, 73% males). The median duration after revascularization was 60 months. One hundred and 4 (51%) patients had previous percutaneous coronary intervention, 67 (33%) patients had coronary by-pass graft surgery, and 31 (15%) patients had both of the revascularization procedures. Of all, 46 (23%) patients were engaging in regular physical activity with a median of 2 days per week. Patients were classified into two subgroups according to their physical activity habits. There was no significant difference in age, comorbid conditions or revascularization type between subgroups. In the univariate regression analysis, absence of regular physical activity was associated with female gender, low education level, unemployment, low household income, implantation of bare metal stent (vs. drug eluted stent) and absence of regular follow-up visits. Stepwise multivariate regression analysis concluded that low education level (p=0.01, OR=3.26, 95%CI: 1.31 -8.11), and absence of regular follow-up visits (p=0.04, OR=2.95, 95%CI: 1.01-8.61) were independent predictors of non-adherence of regular physical activity in study subjects. Conclusion: Regular physical activity rates were lower in outpatients with a history of previous coronary revascularization. Education level and regular follow-up visits could influence physical activity adherence in these patients.
