(ie, higher NYHA functional class)2,42; however, the results are not consistent and the majority of studies demonstrated no difference.2,9,14,43–45For example, in one of the larger cohorts, Edelmann et al2investigated 2785 patients with HFrEF compared with 1294 patients with HFpEF and ...
CRT results in improved HRV, increased levels of sympathetic nerve growth factor, and improved presynaptic sympathetic nerve function in patients with HFrEF, in addition to improvements in NYHA class, 6-min walk, and LVEF [60]. The sympathetic inhibition induced by chronic CRT is acutely reversed...
The majority of patients treated with CCM have HFrEF with an LVEF ≤ 35%, thus most of them have also been supported with an ICD. The devices have to be implanted in two separate procedures, as currently there is no device which combines both therapies. Implanting a CCM on top of an ...
The importance of QRS duration regarding the indication for BiV-CRT in patients with heart failure and reduced ejection fraction (HFrEF) must be explicitly emphasized, since CRT has the ability to widen an existing narrow QRS-complex by creating artificial dyssynchrony [48]: In 2013, two studies...

(3)醛固酮受体拮抗剂:推荐在使用 ACEI/ARB/ARNI、β 受体阻滞剂的基础上加用醛固酮受体拮抗剂(Ⅰ,A),可使 NYHA 心功能分级Ⅱ ~ Ⅳ级的 HFrEF 患者获益,降低全因死亡、心血管死亡、猝死和心衰住院风险 [181]。 (4)利尿剂:利尿剂的应用可以减轻水钠潴留,有效缓解心衰患者的呼吸困难及水肿,改善...

Results from this study suggest that sacubitril/valsartan is not associated with worse cognitive outcomes as initially hypothesized on the basis of theoretical concerns about NEP inhibition in the brain, but that, in fact, it may be beneficial for cognitive function among patients with HFrEF.
