Abstract

Objective: To determine whether patients who subsequently drop out of a structured cardiac rehabilitation programme could be prospectively distinguished from those who remain in the programme based upon their initial baseline characteristics. Design: A cohort study. Setting: A referral rehabilitation department in a cardiovascular research and training institute. Subjects: One thousand one hundred and fifteen coronary heart disease patients including patients with ischaemic heart disease, and those undergoing bypass surgery or percutaneous coronary interventions. Interventions: Demographic characteristics, coronary heart disease risk factors, ejection fraction, functional capacity and laboratory tests were considered at baseline. Main measures: Patients who completed all 24 sessions of the cardiac rehabilitation programme were compared with drop-out cases who did not. Results: Four hundred and ninety-nine patients (44.8%) completed the whole cardiac rehabilitation programme. Women (adjusted odds ratio (AOR) 1.817, P < 0.001), older patients (AOR 1.015, P = 0.047), patients with lower risk of coronary heart disease (AOR 1.573, P = 0.008) or lower body mass index (BMI) (AOR 0.945, P = 0.001) and higher waist-to-hip ratio (AOR 12.871, P = 0.009) and those who were non-smokers (AOR 1.779, P = 0.001) were significantly more likely to complete cardiac rehabilitation. Conclusions: Developing interventions to address special needs of young, obese, smoker male patients who have a lower waist-to-hip ratio and higher clinical risk may be important, especially in attempts to retain this high-risk group in cardiac rehabilitation therapy. © 2007 Sage Publications.
