Abstract:

Objective

To compare the clinical outcomes of patients with heart dysfunction treated with extracorporeal membrane oxygenation (ECMO).

Methods

PubMed, the Cochrane Library, Embase and Web of Science were searched from January 1, 1970 to December 31, 2020. Statistical analysis were performed using comprehensive meta-analysis statistical software, version 2.0.

Results

After screening for the relevant studies, 18 studies with 729 patients meeting the inclusion criteria were ultimately included. The results of the meta-analysis revealed that in patients with heart dysfunction who received ECMO intervention, the 1-month mortality rate was 36.7% (95%CI: 0.034-0.905), and in-hospital mortality was 39.8% (95%CI: 0.256-0.560). In addition, 3-month survival rate was 72.8% (95%CI: 0.621-0.814), 6-month hospitalization survival rate was 65.4% (95%CI: 0.522-0.767), and overall survival rate was 67.4% (95%CI: 0.485-0.820). Substantial heterogeneity was observed, however, sensitivity analysis showed the combined estimates were robust. No obvious publication bias existed.

Conclusion

The mid-term survival rates of patients with heart dysfunction treating by ECMO are about 60%. Future studies based on controlled trials are warranted. Subgroup analyses by different ventricular assistant device are also suggested.
