Meta-Analysis of Cardiac Rehabilitation Outcomes by BMI Categories

A systematic review and meta-analysis of 18 studies examining the impact of baseline body mass index on cardiac rehabilitation outcomes. The analysis, conducted by Siwei Tu and published on figshare in 2026, compares outcomes like exercise capacity and lipid profiles across BMI categories. The primary outcome was change in metabolic equivalents, with secondary outcomes including BMI, cholesterol, heart rate, and blood pressure.

Use Cases

• Evaluate the effect of BMI on exercise capacity improvements based on changes in metabolic equivalents.
• Compare lipid profile outcomes between BMI groups based on total cholesterol, HDL, and triglyceride data.
• Analyze heterogeneity in study results across different CR protocols and obesity definitions.
• Inform clinical guidelines for cardiac rehabilitation by synthesizing evidence on patient baseline factors.

Strengths

• Includes 18 studies sourced from four major databases (Web of Science, Embase, PubMed, Scopus).
• Analyzes multiple clinical outcomes: exercise capacity, BMI, lipid profile, heart rate, and blood pressure.
• Registered with PROSPERO (CRD420251153489), indicating a structured review protocol.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• High heterogeneity was noted in most analyses, which may limit the certainty of conclusions.
