BACKGROUND: Myocardial apoptosis is important in the pathogenesis and progression
of myocardial infarction-induced heart failure (MI-HF). Renal sympathetic
denervation (RDN) has become a promising therapeutic strategy for the treatment
of HF. Previous studies have shown that RDN could improve heart function Yao et
al. (Exp Ther Med 14:4104-4110, 2017). However, whether and how RDN regulates
myocardial apoptosis in MI-HF is unclear. This study sought to evaluate the
effects of RDN on cardiac function and apoptosis-related gene expression in MI-HF
dogs. METHODS: Eighteen healthy mongrel dogs were randomly divided into control
group(n?=?6), model group(n?=?6) and treatment group(n?=?6). MI-HF was
established in model group and treatment group by anhydrous alcohol embolization,
after heart failure dogs in the treatment group and model group proceeded
bilateral renal artery ablation and bilateral renal arteriography, respectively.
The cardiac function parameters were evaluated by echocardiographic; the serum
NT-BNP level was detected by ELISA; the degree of myocardial fibrosis was
observed through masson staining; the expression of MMP-2, MMP-9 in the cardiac
were got by immunohistochemistry. TUNEL method was used to observe cardiomyocyte
apoptotsis and calculate the apoptosis index (AI). Relative expression of Bcl-2
and Bax, Caspase3 and GRP78 were detected using RT-PCR and Western Blot. Renal
artery H&E staining and serum creatinine were conducted to access the efficacy
and safety of RDN. RESULTS: Four weeks after RDN, the LVEDD, LVESD and LVEDP
decreased, and the LVEF and LVSP increased in the treatment group compared with
those in the control group (all P?0.05). Moreover, NT-BNP, an indicator of
cardiac function was decreased. Additionally, MMP-2 and MMP-9 levels in the
myocardium decreased significantly in the treatment group. Furthermore, the
levels of Bax, and caspase 3 decreased, while the level of Bcl-2 increased. Thus,
myocardial apoptosis was attenuated in RDN treated dogs. We also found that the
level of GRP78 which is activated in response to endoplasmic reticulum (ER)
stress, was decreased. However, serum creatinine levels were not significantly
different between the RND-treated dogs and the control dogs. CONCLUSION: Cardiac
function was improved by RDN treatment through regulating apoptosis and ER stress
in cardiomyocytes in dogs after MI.
