Research summary
Cardiovascular Disease (CVD) is the leading cause of mortality and morbidity globally (World Health Organization, 2019). Following a myocardial infarction (MI), an individual is at an increased risk of a secondary event (20-50% higher risk post MI), compared to those with no prior CVD (Kerr et al., 2009). Independent of physical activity levels, high amounts of daily sitting is a risk factor for CVD, of which sitting is typically used as an indicator for sedentary behaviour (Bailey et al., 2019). Sedentary behaviour is defined as a waking energy expenditure of less than 1.5 METs (metabolic task equivalent) while in a seated, reclined or lying posture (Tremblay et al., 2017).
Currently, there is little knowledge regarding the prevalence of sedentary behaviour ischaemic heart disease. The aim of this study is therefore to measure activity levels of an individual following a diagnosis of ischaemic heart disease, alongside its association to cardiac function and cardiovascular risk factors. Sitting patterns and physical activity will be monitored 24 h/day during each condition using an activPAL activity monitor (PAL Technologies, Glasco, Scotland). This will measure changes in posture and level of activity by cadence.REC name
