  1. Investigating the effectiveness of a Stage IVCardiac Rehabilitation Programme A collaborative project between Heartbeat NW and UCLan

  2. What is the context? • Stage IV programmes seek to improve risk factor profile, fitness and general health. • Phase I-III well documented in literature. • Little information relating to late stage (phase IV) cardiac rehabilitation. • Efficacy

  3. What did we do? • Graduate intern employed to review existing data. • Supervisory team will complete the review. • Many, many pages of numbers to review!

  4. Key research question? • How effective was the Heartbeat intervention? • Body mass index (BMI) • Risk factor score, derived from the Framingham methodology (D'Agostino et al. 2000). • Maximal oxygen consumption (VO2 max) determined using a graded exercise test. • Pre- and post- stage IV intervention. • Average duration of the programme was 48±18 wks. • Programme consisted of formal exercise classes (2 per week) and health education sessions.

  5. What did we find?

  6. Implications? • Risk factor score reduced significantly in both genders (p=0.001, ES = 0.99) VO2 max scores improved significantly in both genders (p=0.02, ES = 0.72) • A non-significant reduction in BMI was also observed (p>0.05). • Remove the jargon, Heartbeat intervention did see a significant effect. • Structured exercise/education based cardiac rehabilitation programme successfully improved risk factor profile and aerobic fitness. • Similar findings by gender group. • Multi-faceted improvements in health and wellness. • Supporting evidence that engagement with stage IV programme reduced smoking behaviors.

  7. Where do we go now? • Further investigation of follow up, post cessation of the programme. • Assessment of relatively meager changes in body mass index/body size. • More detailed examination/verification of risk factor score. • Comparisons with more suitable QRISK instruments (Hippisley-Cox et al. 2007). • More data crunching! • Develop a strong evidence-based approach. • Interest nationally (Evidence Live)
