The clinical outcomes of reni-angiotensin system inhibitors for patients after transcatheter aortic valve replacement: A systematic review and meta-analysis.

AIMS

The objective of our systematic reviews and meta-analysis is to evaluate the clinical outcomes of RAS inhibitors for patients after TAVR.

METHODS AND RESULTS

We performed a comprehensive search for Embase, Pubmed, and Cochrane databases from inception to May 1, 2022. The analysis of all outcomes was performed using the random-effects model. In total, 7 articles with a total of 32,585 patients (RAS inhibitor, = 14,871; Controls, = 17,714) were included in our study. There was a significantly lower rates of all-cause mortality (RR = 0.76, 95%Cl = 0.68 to 0.86, < 0.01), cardiovascular death (RR = 0.66, 95%Cl = 0.59-0.74, < 0.01) and HF readmission (RR = 0.87, 95%Cl = 0.80-0.94, < 0.01) in patients with RAS inhibitors compared with controls. Patients with RAS inhibitors also had lower rates of all-cause mortality (RR = 0.82, 95%Cl = 0.76-0.89, < 0.01) and cardiovascular death (RR = 0.73, 95%Cl, 0.62-0.85, < 0.01) after propensity matching.

CONCLUSIONS

In conclusion, our systematic reviews and meta-analysis demonstrated that RAS inhibitors could improve the clinical outcomes for patients after TAVR. Further large and high-quality trials should be conducted to support the use of RAS inhibitors for patients after TAVR.
