ABSTRACT
BACKGROUND/OBJECTIVE:
Nowadays, increasing clinical evidence on metabolic and weight-loss effects of bariatric surgery on improving cardiac structure in obese patients, but its application in improving the cardiac function of HF (heart failure) patients remains controversial. The objective of this meta-analysis was to assess the effects of BS on cardiac function by quantifying the changes of LVEF (left ventricular ejection fraction) and NYHA (New York Heart Association classification) after operations in non-HFpEF (heart failure and preserved ejection fraction) patients.METHODS:
Articles were searched using PubMed and Embase from inception to December 9, 2022, and the Minors scale was used for quality assessments. The included patients should be non-HFpEF and clinically severely obese, and their pre-operative and post-operative values of LVEF or NYHA should be reported.RESULT:
Nine studies involving 146 patients were eventually included with a final result showing that the cardiac functional parameters were improved in non-HFpEF patients. After a weighted mean follow-up time of 15.8 months, the mean NYHA decreased by 0.59 (I2 = 0; 95% CI 0.27 ~ 0.92; p = 0.003), and the mean LVEF increased by 7.49% (I2 = 0; 95% CI - 9.99 ~ - 4.99; p < 0.00001).CONCLUSION:
Bariatric surgery offers beneficial cardiac effects on non-HFpEF patients with obesity but failed to show a significant improvement in the pooled analysis for the changes of cardiac parameters. The improving degree may be related to the baseline BMI, the extent of BMI loss, and the baseline age. Future studies should focus on finding out the influencing factors of effectivenesses and defining the suitable crowd.Palavras-chave
