Personalized Cardiac Rehab Ups Survival in HF With Reduced EF


The study covered in this summary was published in medRxiv.org as a preprint and has not yet been peer reviewed.

Key Takeaways

  • Enrollment in a personalized, home-based multidisciplinary heart failure (HF) outreach program was associated with a significant reduction in all-cause mortality at a median of 2.6 years’ follow-up.

  • Participants also had fewer and shorter HF hospitalizations, and were more likely to be on guideline-directed medical therapy.

Why This Matters

  • HF is a global pandemic affecting at least 26 million people worldwide, and is increasing in prevalence.

  • HF survival remains worse than that of prostate, bowel, and breast cancers.

  • Previous research had demonstrated that multimodal, multidisciplinary cardiac rehabilitation programs are safe and improve exercise capacity and quality of life, but have not shown a significant, consistent reduction in mortality.

Study Design

  • This was an observational, registry-based study of adults with HF with reduced ejection fraction (<50%) treated for an episode of symptomatic HF at any hospital within the South Western Sydney Local Health District, Australia, and invited to participate in the HF outreach service between March 2011 and January 2016.

  • A total of 470 patients were enrolled in the outreach program and 348 were not.

  • The multidisciplinary intervention, led by a specialist HF nurse, included: regular home visits consisting of physical examination, fluid status assessment, and medication review; consistent education on medication compliance, side effects management, and support; dietary advice and education, including dietician home visits; prescribed physical exercises performed under supervision and tailored to individual patient needs.

  • Researchers examined all-cause mortality, rate of optimal medical therapy, HF hospitalizations, and total lengths of stay over a median of 978 days.

Key Results

  • The primary outcome of all-cause mortality was lower among enrolled vs non-enrolled patients (26% vs 38.2%; P < .001).

  • Enrolled patients had fewer recurrent HF admissions (>3 admissions; 16.2% vs 35.6%; P < .001).

  • Enrolled patients had reduced median admission days (14.5 vs 22 days; P < .001).

  • Enrolled patients were more likely to be on guideline-directed medical therapy (76.6% vs 56.6%; P < .001).

  • Enrollment status was the strongest independent predictor of survival (odds ratio [OR], 0.606; P = .003), followed by statin therapy (OR, 0.682; P = .019).

Limitations

  • The analysis lacked randomization and was retrospective.

  • The non-enrolled cohort could have declined enrollment due to multiple factors, such as complex medical conditions, psychological and behavioral factors, and poor health literacy and adherence, which could have independently led to the observed worse outcomes.

  • Mortality data were collected from multiple sources, possibly introducing slight inaccuracies.

  • The outreach service is a labor- and expertise-intensive program that works well within its setting but could be difficult to replicate in other health systems with different economic structures, limiting the generalizability of the findings.
