Long-term risk factor control after a cardiac rehabilitation programme.

Area of Science:

• Cardiology
• Public Health
• Rehabilitation Medicine

Background:

• Myocardial infarction (MI) survivors require long-term management of cardiovascular risk factors.
• Cardiac rehabilitation (CR) programs aim to improve patient outcomes and reduce future cardiac events.
• Understanding the long-term benefits of CR beyond the initial program is crucial for patient care.

Purpose of the Study:

• To compare long-term (18-36 months post-MI) risk factor control, self-rated health, and return to work rates between Phase II cardiac rehabilitation participants (CRP) and non-participants (NP).
• To evaluate the effectiveness of a Phase II CR program in Australia on sustained patient outcomes.

Main Methods:

• A comparative study was conducted involving participants and non-participants of a Phase II cardiac rehabilitation program.
• Data on total cholesterol, exercise habits, blood pressure control, self-rated health perception, and return to work were collected and analyzed.
• Statistical analysis was performed to determine significant differences between the CRP and NP groups.

Main Results:

• CRP demonstrated significantly better long-term control for total cholesterol levels (TC < = 6.5 mmol/L) compared to NP (7% vs. 28%, p = 0.006).
• CRP were more likely to engage in regular exercise (79% vs. 61%, p = 0.038).
• No significant differences were observed between CRP and NP in achieving blood pressure targets, return to work rates, or self-rated health perception.

Conclusions:

• Phase II cardiac rehabilitation participants exhibited superior long-term management of specific cardiovascular risk factors, notably cholesterol levels and exercise adherence, compared to non-participants.
• While CR improved certain risk factor controls, its impact on blood pressure, return to work, and perceived health was comparable between participants and non-participants.
• The study highlights the value of CR in promoting sustained risk factor modification and provides a basis for ongoing outcome assessments in Australian CR programs.
