The effects of bariatric surgery on cardiac function: a systematic review and meta-analysis
Authors' conclusion
Bariatric surgery led to reverse remodelling and improvement in cardiac geometry and function driven by metabolic and haemodynamic factors.

Pooled result
As reported in the abstract
Cardiac geometry and function after surgery
- Decrease in left ventricular (LV) mass index
- 12.2% (95% CI 0.096-0.149; p < 0.001)
- Increase in E/A ratio
- 0.155 (95% CI 0.106-0.205; p < 0.001)
- Decrease in left atrial diameter
- 2.012 mm (95% CI 1.356-2.699; p < 0.001)
- Decrease in LV diastolic dimension
- 1.16 mm (95% CI 0.62-1.69; p < 0.001)
- Increase in LV ejection fraction
- 1.636% (95% CI 0.706-2.566; p < 0.001)
