Representative tracings showing the effects of intracerebroventricular (ICV) TACE inhibitor TAPI-1 on blood pressure (BP), heart rate (HR) and renal sympathetic nerve activity (RSNA) in (A) sham-operated (Sham) and (B) heart failure (HF) rats. BP, mmHg; HR, beats/min (bpm): RSNA, windowed (spikes/s) and integrated (mV) activity. (C), Grouped data showing the change (Δ) from baseline in mean blood pressure (MBP, mmHg), HR (bpm) and RSNA (%) elicited by ICV TAPI-1 in Sham and HF rats. Integrated RSNA was used for data analysis. Values are expressed as means ± SEM (n=6 in each group). * p<0.05, compared with baseline; † p<0.05 compared with Sham.
