Objective: To study the cardiac sympathetic nerve block in different cause of heart failure. Methods: Froty eight cases of dilated ardiomyopathy=16 cases (group A) and ischemic cardiomyopathy=16 cases (group B), valvular disease (group C-16 cases) in patients with heart failure heart were treated with cardiac sympathetic nerve block treatment for 28 days.Results: Eeach index in C group after treatment obviously improved compared with A, B two groups, each index in group A versus in group B also had significant differences, (P<0.01). (Left ventricular ejection fraction (LVEF) increased significantly (P<0.01), left ventricular end-diastolic diameter (LVEDD) significantly reduced (P<0.01), N-terminal brain natriuretic peptide precursor (NT-proBNP) levels significantly decreased (P<0.01). total effective rate of group C was 100%, which was significantly higher than that of A (93.75%) and B (81.25%) groups.Conclusion: Cardiac sympathetic nerve block in patients with severe heart failure therapy is of remarkable help, whose effect is the best in valvular disease, followed by dilated ardiomyopathy and then ischemic cardiomyopathy. |
