Arterial stiffness is one of the major risk factors and markers of cardiovascular disease (CVD). An increase in the arterial stiffness is influenced by various factors such as age, lifestyle, genetics and the presence of other cardiovascular risks such as obesity and diabetes. Arterial stiffness is a consistent thread in this thesis. This thesis investigates the effects of exercise-based management programmes for CVD and risk factors with a focus on carotid-radial applanation tonometry which is a specific non-invasive technique for measuring arterial stiffness. Erectile dysfunction is a marker of CVD and is associated with endothelial dysfunction that leads to arterial stiffness. The effects of centrebased, supervised and exercise-based cardiac rehabilitation (CR) programmes were studied on the changes in arterial stiffness, erectile dysfunction and quality of life of patients with CVD. Despite the effectiveness of CR programmes, there is poor attendance at these programmes and unsupervised home-based, IT (information technology)-supported programmes could improve patient participation and cost effectiveness. Moreover, earlier identification of risks and appropriate management can reduce the incidence of CVD. There are no such programmes for early stages of CVD in practice, especially in developing countries such as India. A 12-week, IT-supported home-based exercise programme in India, for patients with metabolic syndrome was developed and studied. In general, arterial stiffness was improved in both centre-based and home-based exercise programmes. There were acute increases in arterial stiffness following exercise in healthy Caucasians and South Asians as well as people with metabolic syndrome. Carotid-radial pulse wave analysis could be a simple and reliable prognostic tool in exercise based rehabilitation programmes.
