Primary endpoints of the study were changes in muscle sympathetic nerve activity (MSNA) and peripheral chemosensitivity measured as ventilatory response to hypoxia from baseline to 1 month post-CB resection. Safety analysis included analysis of arterial blood gas and oxygenation at night through 2 months post-procedure and adverse events assessed up to 12 months. At the 1-month visit, CB resection was associated with a significant decrease both in MSNA (86.6 \u00b1 3.1 vs. 79.7 \u00b1 4.2 bursts\/100 beats, P = 0.03) and in peripheral chemosensitivity (1.35 \u00b1 0.19 vs. 0.41 \u00b1 0.17 L\/min\/SpO2, P = 0.005). It also resulted in improved exercise tolerance. Amongst some patients with bilateral CB resection, there was a trend towards worsening of oxygen saturation at night, which in one case required therapy with non-invasive ventilation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>We present first-in-man evidence that CB resection in patients with systolic heart failure is associated with a decrease in sympathetic activity.
