Article Synopsis
  • Cardiac rehabilitation (CR) is crucial for patients with cardiovascular disease (CVD), but many struggle to participate due to accessibility issues; home-based CR (HBCR) offers a promising alternative.
  • A study surveyed 189 patients with heart issues, revealing that only 26.5% engaged in adequate exercise, with a preference for individual or family workouts, particularly walking and resistance exercises done at home or outside.
  • Major barriers to exercise included fatigue, poor health self-perception, and low fitness levels, highlighting the need for personalized HBCR programs that accommodate individual preferences and challenges.
