A Meta-Analysis of eHealth Interventions on Ischaemic Heart Disease Health Outcomes

Area of Science:

• Cardiology
• Digital Health
• Public Health

Background:

• Electronic Health (eHealth) interventions are increasingly utilized for secondary prevention in ischaemic heart disease (IHD) patients.
• These interventions aim to empower patients in health decision-making and behavior modification.
• A growing body of evidence supports the efficacy of eHealth interventions in managing chronic conditions.

Approach:

• A systematic meta-analysis was conducted following PRISMA guidelines, searching major databases for randomized controlled trials (RCTs) published between 2011 and 2021.
• Included studies focused on eHealth interventions for IHD patients, assessing various physical and non-physical health outcomes.
• Data analysis involved RevMan 5.4 for meta-analysis and risk of bias assessment, GRADE software for physical outcomes, and SWiM for non-physical outcomes.

Key Points:

• The meta-analysis included 10 studies, with six RCTs (895 participants) analyzed for physical health outcomes.
• eHealth interventions demonstrated a significant improvement in lowering low-density lipoprotein (LDL) cholesterol levels in IHD patients after 12 months (SMD -0.26, p=0.01).
• Significant improvements were also observed in medication adherence, physical activity, and dietary behavior, though other behavioral, psychological, and quality of life outcomes were inconclusive.

Conclusions:

• eHealth interventions show long-term effectiveness in reducing LDL cholesterol for IHD patients.
• The benefits of eHealth interventions for other physical and non-physical health outcomes in IHD patients are not yet conclusive.
• Future research should focus on integrating sustainable patient empowerment strategies with advanced eHealth interventions using appropriate frameworks.
