- AimsEarly start and patient profile-oriented heart failure (HF) management has been recommended. In this post hoc analysis from the SHIFT trial, we analysed the treatment effects of ivabradine in HF patients with systolic blood pressure (SBP) < 110 mmHg, resting heart rate (RHR) & GE; 75 b.p.m., left ventricular ejection fraction (LVEF) & LE; 25%, New York Heart Association (NYHA) Class III/IV, and their combination. Methods and resultsThe SHIFT trial enrolled 6505 patients (LVEF & LE; 35% and RHR & GE; 70 b.p.m.), randomized to ivabradine or placebo on the background of guideline-defined standard care. Compared with placebo, ivabradine was associated with a similar relative risk reduction of the primary endpoint (cardiovascular death or HF hospitalization) in patients with SBP < 110 and & GE;110 mmHg [hazard ratio (HR) 0.89, 95% confidence interval (CI) 0.74-1.08 vs. HR 0.80, 95% CI 0.72-0.89, P interaction = 0.34], LVEF & LE; 25% and >25% (HR 0.85, 95% CI 0.72-1.01 vs. HR 0.80, 95% CI 0.71-0.90, P interaction = 0.53), and NYHA III-IV and II (HR 0.83, 95% CI 0.74-0.94 vs. HR 0.81, 95% CI 0.69-0.94, P interaction = 0.79). The effect was more pronounced in patients with RHR & GE; 75 compared with <75 (HR 0.76, 95% CI 0.68-0.85 vs. HR 0.97, 95% CI 0.81-0.1.16, P interaction = 0.02). When combining these profiling parameters, treatment with ivabradine was also associated with risk reductions comparable with patients with low-risk profiles for the primary endpoint (relative risk reduction 29%), cardiovascular death (11%), HF death (49%), and HF hospitalization (38%; all P values for interaction: 0.40). No safety concerns were observed between study groups. ConclusionsOur analysis shows that RHR reduction with ivabradine is effective and improves clinical outcomes in HF patients across various risk indicators such as low SBP, high RHR, low LVEF, and high NYHA class to a similar extent and without safety concern.

- Abstract Aims This study aims to explore possible associations between self‐efficacy and healthcare and drug expenditures (i.e. direct costs) in patients with chronic heart failure (CHF) or chronic obstructive pulmonary disease (COPD) in a study investigating the effects of person‐centred care delivered by telephone. Methods and results This exploratory analysis uses data from an open randomized controlled trial conducted between January 2015 and November 2016, providing remote person‐centred care by phone to patients with CHF, COPD, or both. Patients hospitalized due to worsening of CHF or COPD were eligible for the study. Randomization was based on a computer‐generated list, stratified for age ≥ 75 and diagnosis. At a 6 month follow‐up, 118 persons remained in a control group and 103 in an intervention group. The intervention group received person‐centred care by phone as an addition to usual care. Trial data were linked to register data on healthcare and drug use. Group‐based trajectory modelling was applied to identify trajectories for general self‐efficacy and direct costs. Next, associations between self‐efficacy trajectories and costs were assessed using regression analysis. Five trajectories were identified for general self‐efficacy, of which three indicated different levels of increasing or stable self‐efficacy, while two showed a decrease over time in self‐efficacy. Three trajectories were identified for costs, indicating a gradient from lower to higher accumulated costs. Increasing or stable self‐efficacy was associated with lower direct costs ( P = 0.0013). Conclusions The findings show that an increased or sustained self‐efficacy is associated with lower direct costs in patients with CHF or COPD. Person‐centred phone contacts used as an add‐on to usual care could result in lower direct costs for those with stable or increasing self‐efficacy.

- Ivabradine has been approved in heart failure with reduced ejection fraction (HFrEF) and elevated heart rate despite guideline-directed medical therapy (GDMT) to reduce cardiovascular (CV) death and hospitalization for worsening HF. The median value of 77 b.p.m. is the lower bound selected for the regulatory approval in Canada, South Africa, and Australia. Patient-reported outcomes (PROs) including symptoms, quality of life, and global assessment are considered of major interest in the global plan of care of patients with HF. However, the specific impact of GDMT, and specifically ivabradine, on PRO remains poorly studied. In the subgroup of patients from the Systolic Heart failure treatment with the If inhibitor ivabradine Trial (SHIFT) who had heart rate above the median of 77 b.p.m. (pre-specified analysis) and for whom the potential for improvement was expected to be larger, we aimed (i) to evaluate the effects of ivabradine on PRO (symptoms, quality of life, and global assessment); (ii) to consolidate the effects of ivabradine on the primary composite endpoint of CV death and hospitalization for HF; and (iii) to reassess the effects of ivabradine on left ventricular (LV) remodelling.Comparisons were made according to therapy, and proportional hazards models (adjusted for baseline beta-blocker therapy) were used to estimate the association between ivabradine and various outcomes. In SHIFT, n = 3357 (51.6%) patients had a baseline heart rate > 77 b.p.m. After a median follow-up of 22.9 months (inter-quartile range 18-28 months), ivabradine on top of GDMT improved symptoms (28% vs. 23% improvement in New York Heart Association functional class, P = 0.0003), quality of life (5.3 vs. 2.2 improvement in Kansas City Cardiomyopathy Questionnaire overall summary score, P = 0.005), and global assessment [from both patient (improved in 72.3%) and physician (improved in 61.0%) perspectives] significantly more than did placebo (both P < 0.0001). Ivabradine induced a 25% reduction in the combined endpoint of CV death and hospitalization for HF (hazard ratio 0.75; P < 0.0001), which translates into a number of patients needed to be treated for 1 year of 17. Patients under ivabradine treatment demonstrated a significant reduction in LV dimensions when reassessed at 8 months (P < 0.05).In patients with chronic HFrEF, sinus rhythm, and a heart rate > 77 b.p.m. while on GDMT, the present analysis brings novel insights into the role of ivabradine in improving the management of HFrEF, particularly with regard to PRO (ISRCTN70429960).

- Aims Angiotensin receptor blockers have been shown to reduce heart failure hospitalization and cardiovascular mortality in men and women with heart failure with reduced ejection fraction (HFrEF). It is unknown whether there are differences between men and women in achieved dose and treatment discontinuation due to adverse events of candesartan. Methods and results We conducted a post hoc analysis of the Candesartan in Heart failure: Assessment of Reduction in Mortality and morbidity (CHARM) programme. A total of 3172 men and 1106 women with HFrEF [left ventricular ejection fraction (LVEF) <= 40%] in New York Heart Association class II-IV were randomized to candesartan or placebo. Every 2 weeks, patients were up-titrated from 4 or 8, to16, to 32 mg once daily, unless a higher dose was contraindicated or not tolerated. Women were older (66 vs. 64 years), had a higher LVEF (29.9% vs. 28.6%), and had more hypertension (54% vs. 47%) than men. The mean achieved dose of candesartan was 21.5 +/- 12.6 mg in men and 20.7 +/- 12.9 mg in women (P = 0.19). In both the candesartan and placebo groups, cardiovascular death and heart failure hospitalizations were higher in men and women who achieved lower dose levels. Event rates for achieved dose levels of 0, 4 or 8, 16, and 32 mg candesartan were 20.8, 17.2, 14.0, and 10.1 per 100 person-years in men, respectively, and 23.6, 13.7, 14.0, and 9.1 per 100 person-years in women, respectively. In each of the achieved dose levels, there was no sex difference in the proportion of patients with an event, neither in the candesartan group nor in the placebo group (P-value for all > 0.05). There was no significant interaction between sex and treatment-related discontinuation for hypotension (P = 0.520), an increase in creatinine (P = 0.102), and hyperkalaemia (P = 0.905). Conclusions In a randomized clinical trial in patients with HFrEF, men and women achieved similar doses of candesartan. Primary event rates and treatment-related discontinuation due to adverse events were also similar between men and women.

- Aims Little is known about patient characteristics, outcomes, and the effect of treatment in relation to duration of heart failure (HF). We have investigated these questions in PARADIGM-HF. The aim of the study was to compare patient characteristics, outcomes, and the effect of sacubitril/valsartan, compared with enalapril, in relation to time from HF diagnosis in PARADIGM-HF. Methods and results HF duration was categorized as 0-1, >1-2, >2-5, and >5 years. Outcomes were adjusted for prognostic variables, including N-terminal pro-brain natriuretic peptide (NT-proBNP). The primary endpoint was the composite of HF hospitalization or cardiovascular death. The number of patients in each group was as follows: 0-1 year, 2523 (30%); >1-2 years, 1178 (14%); >2-5 years, 2054 (24.5%); and >5 years, 2644 (31.5%). Patients with longer-duration HF were older, more often male, and had worse New York Heart Association class and quality of life, more co-morbidity, and higher troponin-T but similar NT-proBNP levels. The primary outcome rate (per 100 person-years) increased with HF duration: 0-1 year, 8.4 [95% confidence interval (CI) 7.6-9.2]; >1-2 years, 11.2 (10.0-12.7); >2-5 years, 13.4 (12.4-14.6); and >5 years, 14.2 (13.2-15.2);P < 0.001. The hazard ratio was 1.26 (95% CI 1.07-1.48), 1.52 (1.33-1.74), and 1.53 (1.33-1.75), respectively, for >1-2, >2-5, and >5 years, compared with 0-1 year. The benefit of sacubitril/valsartan was consistent across HF duration for all outcomes, with the primary endpoint hazard ratio 0.80 (95% CI 0.67-0.97) for 0-1 year and 0.73 (0.63-0.84) in the >5 year group. For the primary outcome, the number needed to treat for >5 years was 18, compared with 29 for 0-1 year. Conclusions Patients with longer-duration HF had more co-morbidity, worse quality of life, and higher rates of HF hospitalization and death. The benefit of a neprilysin inhibitor was consistent, irrespective of HF duration. Switching to sacubitril/valsartan had substantial benefits, even in patients with long-standing HF.
