Slow breathing increases arterial baroreflex sensitivity in patients with chronic heart failure

It is well established that a depressed baroreflex sensitivity may adversely influence the prognosis in patients with chronic heart failure (CHF) and in those with previous myocardial infarction. We tested whether a slow breathing rate (6 breaths/min) could modify the baroreflex sensitivity in 81 pa...

Description
Summary:It is well established that a depressed baroreflex sensitivity may adversely influence the prognosis in patients with chronic heart failure (CHF) and in those with previous myocardial infarction. We tested whether a slow breathing rate (6 breaths/min) could modify the baroreflex sensitivity in 81 patients with stable (2 weeks) CHF (age, 58+/-1 years; NYHA classes I [6 patients], II [33], III [27], and IV [15]) and in 21 controls. Slow breathing induced highly significant increases in baroreflex sensitivity, both in controls (from 9.4+/-0.7 to 13.8+/-1.0 ms/mm Hg, P
