Abstract:
Objective To investigate the effect of renal sympathetic denervation (RSD) on the activity of renalase in dogs with chronic heart failure (CHF).Methods After induced by abdominal aorta constriction,dogs were divided into three groups according to whether they underwent double renal artery ablation:2 dogs in control group,2 dogs in sham-operated group (no renal artery ablation),and 5 dogs in RSD group (renal artery ablation).Plasma noradrenaline (NE),B-type natriuretic peptide (BNP),and renalase were determined in 5 dogs with RSD (RSD group),2 control dogs (control group),and 2 shamoperated dogs (sham-operated group).Results NE,BNP and heart rate were significantly higher and renalase was lower in CHF group than those in control group (all P ＜ 0.05).Compared to the control dogs with CHF,the levels of renalase were significantly increased in 6 weeks after RSD [(1 948.78 ±49.19) ng/ml vs (1 847.35 ±20.72)ng/ml,P =0.029],and NE [(166.30 ±7.68)pg/ml vs (181.29 ±8.57)pg/ml],and BNP [(75.10 ± 5.58)lμg/ml vs (89.79 ± 2.04) μg/ml] were decreased in 8 weeks after RSD (all P ＜ 0.05).An decreased trend of the levels of renalase was observed in 8 weeks than in 6 weeks in CHF dogs after RSD,without significant difference (P ＞ 0.05).Conclusions The activity of renalase in dogs with CHF can be affected by RSD.
