The efficacy of mindfulness-based intervention for heart diseases: A meta-analysis of randomized controlled trials.
Study Goal
The researchers aimed to determine the impact of mindfulness-based intervention on heart diseases through a systematic review and meta-analysis of randomized controlled trials.
Results Summary
Mindfulness-based intervention significantly improved 6-minute walking test results, reduced heart rate and stress scores, but showed no significant impact on anxiety scores or respiratory rates in patients with heart diseases.
Population
458 patients with heart diseases across five randomized controlled trials.

| Intervention | Direction | Endpoint | Population | Dosage | Impact | Claim # |
|---|---|---|---|---|---|---|
mindfulness-based intervention | increase | 6 minute walking test | patients with heart diseases | mean difference (MD) = 14.74; 95% confidence interval (95% CI) = 2.50-26.97; P = .02 | significantly increased | #1 |
mindfulness-based intervention | decrease | heart rate | patients with heart diseases | mean difference (MD) = -2.54; 95% confidence interval (95% CI) = -4.76 to -0.31; P = .03 | decreased | #2 |
mindfulness-based intervention | decrease | stress score | patients with heart diseases | mean difference (MD) = -2.31; 95% confidence interval (95% CI) = -4.23 to -0.38; P = .02 | decreased | #3 |
mindfulness-based intervention | no change | anxiety score | patients with heart diseases | mean difference (MD) = -3.48; 95% confidence interval (95% CI) = -7.98 to 1.03; P = .13 | shows no obvious impact | #4 |
mindfulness-based intervention | no change | respiratory rate | patients with heart diseases | mean difference (MD) = -0.42; 95% confidence interval (95% CI) = -1.31 to 0.46; P = .35 | shows no obvious impact | #5 |
INTRODUCTION: The efficacy of mindfulness-based intervention for heart diseases remains controversial. We conduct a systematic review and meta-analysis to explore the impact of mindfulness-based intervention on heart diseases. METHODS: We have search PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through August 2020 for randomized controlled trials (RCTs) assessing the effect of mindfulness-based intervention versus usual care on heart diseases. This meta-analysis is performed using the random-effect model. RESULTS: Five RCTs involving 458 patients are included in the meta-analysis. Overall, compared with control group for heart diseases, mindfulness-based intervention is associated with significantly increased 6 minute walking test [mean difference (MD) = 14.74; 95% confidence interval (95% CI) = 2.50-26.97; P = .02], decreased heart rate (MD = -2.54; 95% CI = -4.76 to -0.31; P = .03) and stress score (MD = -2.31; 95% CI = -4.23 to -0.38; P = .02), but shows no obvious impact on anxiety score (MD = -3.48; 95% CI = -7.98 to 1.03; P = .13) or respiratory rate (MD = -0.42; 95% CI = -1.31 to 0.46; P = .35). CONCLUSIONS: Mindfulness-based intervention can provide additional benefits to heart diseases.
