Abstract Background Previous studies highlighted the importance of adequate heart rate control in heart failure patients, and suggested under-treatment with beta-blockers especially in women. However, data on women achieving effective heart rate control during beta-blocker therapy optimization are lacking. Methods The wearable cardioverter defibrillator (WCD) allows continuous monitoring of heart rate (HR) trends during WCD use. In the current study, we assessed resting HR trends (nighttime: midnight-7am) in women, both at the beginning of WCD use and at the end of WCD use to assess the adequacy of beta-blockade following a typical 3 months of therapy optimization with beta-blockers. An adequate heart rate control was defined as having a nighttime HR <70 bpm at the end of the 3 months. Results There were a total of 21,453 women with at least 30 days of WCD use (>140 hours WCD use on the first and last week). The mean age was 67 years (IQR 58–75). The mean nighttime heart rate was 72 bpm (IQR 65–81) at the beginning of WCD use, that decreased to 68 bpm (IQR 61–76) at the end of WCD use with therapy optimization. Women had an insufficient heart rate control with resting heart rate ≥70 bpm in 59% at the beginning of WCD use that decreased to 44% at the end of WCD use, but still remained surprisingly high. Interestingly, there were 21% of the women starting with HR ≥70 bpm at the beginning of use (BOU) who achieved adequate heart rate control by the end of use (EOU). Interestingly, 6% of women with adequate heart rate control at the start of therapy optimization ended up having higher heart rates >70 bpm at the end of the therapy optimization time period (Figure). Figure 1 Conclusions A significant proportion of women with heart failure and low ejection fraction do not reach an adequate heart rate control during the time of beta blocker initiation/titration. The wearble cardioverter defibrillator is a monitoring device that has been demonstrated in this study to appropriately identify patients with inadequate heart rate control at the end of the therapy optimization period. The WCD could be utilized to improve management of beta-blocker therapy in women and improve the achievement of adequate heart rate control in women.

The novel first-in-class If channel antagonist, Ivabradine, is effective in improving clinical outcomes and functional capacity, in patients with HF, as well as demonstrating useful anti-anginal and protective anti-ischaemic effects. It can help improve heart rate control and can be usefully co-administered with beta blockers on HFrEF patients with residually elevated resting sinus rhythm heart rate. We review the clinical trial evidence for the benefits of Ivabradine in the treatment of heart failure.

Abstract Background Whether discharge heart rate for hospitalized heart failure (HF) patients with coexisted atrial fibrillation (AF) is associated with long-term clinical outcomes and whether this association differs between patients with and without beta-blockers have not been well studied. Purpose We investigated the associations between discharge heart rate and clinical outcomes in hospitalized HF patients with coexisted AF, while stratified to beta-blockers at discharge. Methods The study cohort included 1631 HF patients hospitalized primarily with AF, which was from the China PEACE Prospective Heart Failure Study. Clinical outcome was 1-year combined all-cause mortality and HF hospitalization after discharge. We analyzed association between outcome and heart rate at discharge with restricted cubic spline and Cox proportional hazard ratios (HR). Results The median age was 68 (IQR: 60- 77) years, 41.9% were women, discharge heart rate was (median (IQR)) 75 (69- 84) beats per minute (bpm), and 60.2% received beta-blockers at discharge. According to the result of restricted cubic spline plot, the relationship between discharge heart rate and clinical outcome may be nonlinear (P&lt;0.01). Based on above result, these patients were divided into 3 groups: lowest &lt;65 bpm, middle 65–86 bpm and highest ≥87 bpm, clinical outcomes occurred in 128 (64.32%), 624 (53.42%) and 156 (59.32%) patients in the lowest, middle, and highest groups respectively. In the Cox proportional hazard analysis, the lowest and highest groups were associated with increased risks of clinical outcome compared with the middle group (HR: 1.289, 95% confidence interval (CI): 1.056 - 1.573, p=0.013; HR: 1.276, 95% CI: 1.06 - 1.537, p=0.01, respectively). And a significant interaction between discharge heart rate and beta-blocker use was observed (P&lt;0.001 for interaction). Stratified analysis showed the lowest group was associated with increased risks of clinical outcomes in patients with beta-blockers (HR: 1.584, 95% confidence interval (CI): 1.215–2.066, p=0.001). Conclusion There may be a U-curve relationship between discharge heart rate and clinical outcomes in hospitalized HF patients with coexisted AF. They may have the best clinical outcomes with heart rates of 65 - 86 bpm. And strict heart rate control (&lt;65 bpm) may be avoided for patients who discharge with beta-blockers.
