Adherence to an Exercise and Healthy Diet Program in Patients With Coronary Heart Disease Aged ≥ 60 Years

Long-term adherence to a healthy lifestyle that promotes heart health (e.g. physical activity, healthy diet, non-smoking) is not yet sufficiently achieved in patients with coronary artery disease (≥ 60 years). Individuals in this study will participate in a 3-month multimodal intervention program. The program includes group and individual sessions with a focus on exercise training and healthy nutrition. Positive views on ageing have been shown to be associated with a healthier lifestyle. Therefore, it seems important to consider views on ageing as part of a lifestyle intervention. The intervention program starts with a group session containing information on (i) views on ageing and its association to lifestyle and (ii) how to cope with the diagnosis of coronary heart disease in everyday life.The physical exercise training and nutrition intervention will be carried out at least twice a week for at least 60 minutes each and for a period of 3 months. During this time, participants will receive instructions to exercise regularly and adjust their nutrition according to the recommendations. The physical exercise training and nutritional recommendations should be implemented at home. Study participants who smoke tobacco will be motivated to participate in a smoking cessation program. If they are not willing to do this, short, motivating interviews on smoking cessation will be offered. A pilot study will be conducted using a pre-post design. Patients will be followed over time and data will be collected on anthropometrics, blood samples, cardiopulmonary exercise tests, and 7-day accelerometry at baseline and at 3- and 12-month follow-ups.
