Abstract/OtherAbstract:
We investigated whether coexisting renal insufficiency (RI) is associated with elevated sympathetic activity in patients with heart failure (HF). Resting muscle sympathetic nerve activity (MSNA) was determined in 101 patients with HF (ejection fraction<0.45) and 8 patients with RI but without HF (RI group). Diagnosis of RI was made of glomerular filtration rates <60ml/min/1.73m(2) estimated using the simplified Modification of Diet in Renal Disease equation. Of 101 patients, 45 had RI (HFRI group) and 56 did not (HF group). HFRI group was older (p<0.05) and given loop diuretics more frequently (p<0.05), and had a lower specific activity scale (p<0.05) than HF group. HFRI group exhibited significantly greater MSNA indices than either HF group or RI group (burst rate, p<0.05; burst incidence, p<0.01). Univariate analysis showed that RI, age, specific activity scale level and dose of furosemide were significant predictors of increased burst incidence of MSNA in patients with HF. Notably, multivariate analysis revealed that RI was the only independent factor for increased MSNA indices. These findings suggest that coexisting RI is associated with elevated sympathetic activity in patients with HF.
