What is the clinical evidence from this study?

Study design: Observational. Population: Patients referred to home-based cardiac rehabilitation (n=280). Intervention: Home-based cardiac rehabilitation vs. Baseline (before starting CR). Primary outcome: Moderate to vigorous physical activity (MVPA) in minutes per week.

What question did this study set out to answer?

To evaluate moderate to vigorous physical activity levels during a home-based cardiac rehabilitation program and determine how demographic and clinical factors moderate physical activity engagement.

Key result

A 3-month home-based cardiac rehabilitation program increased moderate to vigorous physical activity from 88.5 to 191.1 minutes per week, moderated by gender and metabolic syndrome.

Implication

May support home-based programs in select patients; hypothesis-generating and requires randomized confirmation before practice change.

Key Points

To evaluate moderate to vigorous physical activity levels during a home-based cardiac rehabilitation program and determine how demographic and clinical factors moderate physical activity engagement.
Assessed N = 280 cardiac patients (77 female) referred to a 3-month home-based cardiac rehabilitation program following myocardial infarction (34%), percutaneous coronary intervention (32%), or coronary artery bypass graft (17%).
Measured self-reported weekly moderate to vigorous physical activity (MVPA) alongside clinical parameters from medical chart reviews at the beginning and end of the 3-month program.
Conducted multiple regression analyses to identify demographic and clinical determinants of overall MVPA participation and change in MVPA over time.
Average MVPA increased from 88.5 minutes per week before starting the home-based program to 191.1 minutes per week upon completion.
Higher overall MVPA during rehabilitation was predicted by male sex (β = −.11), absence of metabolic syndrome (β = −.14), and meeting baseline MVPA guidelines (β = .25).
Significantly greater increases in MVPA over the 3 months occurred in males (β = −.20), patients without metabolic syndrome (β = −.13), and patients not meeting MVPA guidelines at baseline (β = −.29).

Does a 3-month home-based cardiac rehabilitation program improve moderate to vigorous physical activity in cardiac patients?

Population

280 patients (77 female) referred to home-based cardiac rehabilitation, mainly due to myocardial infarction (34%), coronary artery bypass graft (17%), and percutaneous coronary intervention/stent/atherectomy (32%).

Intervention

3-month home-based cardiac rehabilitation program

Outcome

Moderate to vigorous physical activity (MVPA) measured by questionnaire at the beginning and end of the 3-month programpatient reported

Main Result

Absolute Event Rate: 191.1% vs 88.5%

Home-based cardiac rehabilitation significantly increases moderate to vigorous physical activity, with greater improvements seen in males, those without metabolic syndrome, and those with lower baseline activity levels.
