[Abstract] Objective To systematically assess the curative eff
ect of thyroxine in patients with heart failure complicating low T3 syndrome.
Methods Retrieving
databases including Pubmed, Web of Science, Cochrane Library, CBM, WanFang datab
ase and VIP database. The retrieval time limited from the foundation of databas
e to June 2013. Meantime, references of articles were searched. According to t
he inclusion criterion, relevant articles were screened. After extracting data,
quality of data was assessed, and meta_analysis was performed by RevMan 5.2.
Results A total of 11 RCTs involving 662 patients were included
. The result of meta_an
alyses showed that, compared with the control group, after short_term treatment
with thyroxine, left ventricular ejection fraction (LVEF) and cardiac output (C
O) of the treatment group obviously increased (MD=5.16, 95%CI=3.11~7.21, P
<0.01; MD=0.55, 95%CI=0.33~0.7 P<0.01). Besides, the evaluation ind
ex of ventricular diastolic function E/A was improved and left ventricular end d
iastolic diameter (LVDD) was decreased (MD=0.22, 95%CI=0.09~0.34,P<0.01
; MD=-4.14, 95%CI=-6.66~-1.61,P<0.01).
Conclusions Thyroxine based on routine treatment can improve
the heart ejection function and the ventricular diastolic function for patients
with heart failure complicating low T3 syndrome.endprint
