Abstract
PURPOSE Recent trials suggest glucagon-like peptide-1 receptor agonists (GLP-1RAs) may have a cardioprotective role by reducing major adverse cardiac events, stroke mortality and heart failure-related hospitalisations. We examined whether and how GLP-1RAs affect cardiac function in cardiovascular and metabolic diseases including type 2 diabetes, heart failure and post-myocardial infarction. METHODS In this PRISMA-adherent systematic review and meta-analysis, three databases were searched from inception to July 2021 and registered on PROSPERO (CRD42021259661). RESULTS 20 reports of 19 randomized placebo-controlled trials including 2062 participants were meta-analyzed. Among type 2 diabetes patients, GLP-1RA resulted in improved systolic function measured by circumferential strain (mean difference [MD]= -5.48; 95% CI: -10.47 to -0.49; P= 0.03; I2= 89%) and diastolic dysfunction measured by E / A (MD= -0.15; 95% CI: -0.25 to -0.05; P= 0.003; I2= 0%). For post-myocardial infarction patients, GLP-1RA reduced infarct size (g) (MD= -5.36; 95% CI: -10.68 to -0.04; P= 0.05; I2= 78%). Liraglutide, but not exenatide, demonstrated improved systolic function, by increasing left ventricular ejection fraction (MD= 4.89; 95% CI: 3.62 to 6.16; P< 0.00001; I2= 0%) and reducing left ventricular end-systolic volume (MD= -4.15; 95% CI: -7.49 to -0.81; P = 0.01; I2= 0%). Among heart failure patients, no significant changes were noted. CONCLUSION GLP-1RA drugs may improve systolic and diastolic function in type 2 diabetes and reduce infarct size post-acute myocardial infarction with no demonstrable effect on cardiac function in heart failure. Tailored recommendations for the use of GLP-1RAs for cardioprotection should be considered for each patient's condition.

Abstract
Heart failure with reduced ejection fraction (HFrEF) and nonalcoholic fatty liver disease (NAFLD) are two common comorbidities that share similar pathophysiological mechanisms. There is a growing interest in the potential of targeted therapies to improve outcomes in patients with coexisting HFrEF and NAFLD. This manuscript reviews current and potential therapies for patients with coexisting HFrEF and NAFLD. Pharmacological therapies, including angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, mineralocorticoids receptor antagonist, and sodium-glucose cotransporter-2 inhibitors, have been shown to reduce fibrosis and fat deposits in the liver. However, there are currently no data showing the beneficial effects of sacubitril/valsartan, ivabradine, hydralazine, isosorbide nitrates, digoxin, or beta blockers on NAFLD in patients with HFrEF. This study highlights the importance of considering HFrEF and NAFLD when developing treatment plans for patients with these comorbidities. Further research is needed in patients with coexisting HFrEF and NAFLD, with an emphasis on novel therapies and the importance of a multidisciplinary approach for managing these complex comorbidities.

Abstract
BACKGROUND Heart rate (HR) control is important in heart failure (HF) patients with reduced ejection fraction, and ivabradine is indicated for patients with chronic HF and sinus rhythm. However, ivabradine is limited in initiation of ivabradine at acute stage of HF. MATERIALS AND METHODS This multi-institutional retrospective study enrolled 30,639 patients who were admitted for HF from January 01, 2013 to December 31, 2018 at Chang Gung Memorial Hospitals. After applying selection criteria, the eligible patients were divided into ivabradine and non-ivabradine groups according to the initiation of ivabradine at the index hospitalization. HR, clinical outcomes including HF hospitalization, all-cause hospitalization, mortality, the composite of cardiovascular (CV) death or HF hospitalization and newly developed atrial fibrillation, and left ventricular ejection fraction (LVEF) and left atrium size were compared between the ivabradine and non-ivabradine groups after inverse probability of treatment weighting (IPTW) analysis after 12 months. RESULTS The HR at admission in the ivabradine group (n = 433) was 99.04 ± 20.69/min, compared to 86.99 ± 20.34/min in the non-ivabradine group (n = 9,601). After IPTW, HR was lower in the ivabradine group than that in the non-ivabradine group after 12 months (74.14 ± 8.53 vs. 81.23 ± 16.79 bpm, p = 0.079). However, there were no significant differences in HF hospitalization (HR = 1.02; 95% CI, 0.38-2.79), all-cause hospitalization (HR = 0.95; 95% CI, 0.54-1.68), mortality (HR = 0.87; 95% CI, 0.69-1.08), the composite of CV death or HF hospitalization (HR = 0.87; 95% CI, 0.69-1.08) and newly developed AF between the two groups. In addition, LVEF increased with time in both groups, but there were no significant differences during the observation period. CONCLUSION Ivabradine was beneficial in controlling HR when initiated in patients with acute stage of HF, but it did not seem to provide any benefits in reducing HF hospitalization, all-cause hospitalization, and mortality in 1 year after discharge.

Abstract
BACKGROUND Comorbidity of obstructive sleep apnea (OSA) and heart failure (HF) is becoming increasingly common. This is a global analysis of positive airway pressure (PAP) efficacy for the cardiovascular outcomes in those HF Patients with comorbid OSA. METHODS Related randomized controlled trials were included. Analysed indicators covered primary outcomes (cardiac function, motor ability and life quality) and secondary outcomes (blood pressure and OSA-accompanying symptoms). Weighted mean difference was used to analyse the PAP-control difference in different experimental phases and the baseline-post difference in different groups. RESULTS Compared with control group, PAP was associated with a 3.48% increase in left ventricle ejection fraction (LVEF) (p < .00001) and little decrease in heart rate (HR) (p = .67). Over 6 h of mean nighttime use was associated with a greater increase in LVEF of 5.21% (p = .0002) and a significant reduction in HR of 3.81 bpm (p = .03). There was no significant difference between PAP and control group in their association with change in motor ability and life quality. Besides, PAP was associated with a 13.08 mm Hg decrease in systolic blood pressure and great improvements in OSA-accompanying symptoms: Apnea-Hypopnea Index, -23.73 e/h; mean oxygen saturation, 1.86%; minimum oxygen saturation, 8.78%; Epworth Sleepiness Scale, -1.39 point; arousal index, -16.41 e/h. There was also no significant difference in diastolic blood pressure. CONCLUSIONS Positive airway pressure treatment improves cardiac function in HF patients with comorbid OSA, but the improved magnitude is associated with the duration of nighttime use rather than the duration of treatment.

Abstract
Heart failure (HF) remains one of the cardiovascular diseases (CVDs) associated with a high unmet medical need due to high morbidity and mortality rates and lack of efficacious interventions. HF is closely related to cardiometabolic diseases such as diabetes, obesity and chronic kidney disease, and strategies that address most or all these intertwined conditions are desirable. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are approved for type 2 diabetes (T2D), and some are also indicated for reduction of the risk of atherosclerotic CVD in T2D and for weight management. As we summarise in this concise review, preliminary evidence suggests that the cardioprotective benefits of GLP-1 RAs may also extend to HF. The most robust clinical evidence arguably originates from the large cardiovascular outcomes trials (CVOTs) completed for most GLP-1 RAs, of which the latest showed a significant relative risk reduction (RRR) of 39% (HR) with once-weekly efpeglenatide on HF requiring hospitalisation, corroborating a meta-analysis which found a significant RRR across eight GLP-1 RA CVOTs of 11%. Further, although incompletely described, multiple studies are available to provide insights into the mechanistic underpinnings, which appear to be associated mostly with indirect cardioprotective benefits owing to the ability of GLP-1 RAs to address hyperglycaemia, and reduce body weight, and, amongst others, inflammation. In sum, current evidence positions GLP-1 RAs as a potential cardioprotective strategy in HF, with HF with preserved ejection fraction emerging as the clinically most relevant phenotype for the drug class, especially when occurring in people with obesity with and without diabetes.

Abstract
BACKGROUND Higher resting heart rate (HR) in patients with heart failure (HF) and sinus rhythm (SR) is associated with increased mortality. In patients hospitalized for HF, the aim herein, was to assess the use and dosage of guideline-recommended HR lowering medications, HR control at discharge and predictors of HR control. METHODS In the present study, were Polish participants of the European Society of Cardiology HF Long-Term (ESC-HF-LT) Registry. Those selected were hospitalized for HF, with reduced ejection fraction (HFrEF) and SR at discharge (n = 236). The patients were divided in two groups ( < 70 and ≥ 70 bpm). Logistic regression was used to identify the predictors of HR ≥ 70 bpm. RESULTS Of patients with HFrEF and SR, 59% had HR ≥ 70 bpm at hospital discharge. At discharge, 96% and only 0.5% of the patients with HFrEF and SR received beta-blocker and ivabradine, respectively. In the HF groups < 70 and ≥ 70 bpm, only 11% and 4% of patients received beta-blocker target doses, respectively. There was no difference in the use of other guideline-recommended medications. Age, New York Heart Association class, HR on admission and lack of HR lowering medications were predictors of discharge HR ≥ 70 bpm. CONCLUSIONS Heart rate control after hospitalization for HFrEF is unsatisfactory, which may be attributed to suboptimal doses of beta-blockers, and negligence in use other HR lowering drugs (including ivabradine).

Abstract
Aims Ivabradine has been used in patients who have chronic heart failure (HF) with reduced ejection fraction (HFrEF) and concomitant sinus heart rate ≥70 bpm. This administration for acute HFrEF remains a concern. This study used a real‐world multicentre database to investigate the effects of ivabradine among patients with acute decompensated HFrEF before discharge. Methods and results This study retrospectively identified patients with acute decompensated HFrEF who were administered ivabradine at discharge from two multicentre HF databases. Propensity score matching was performed to adjust for confounders. Cardiovascular mortality, all‐cause mortality, and recurrent HF rehospitalization risks were then compared between those with and without ivabradine treatment. After 1:2 propensity score matching, 876 patients (age, 60.7 ± 14.6 years; female, 23.2%; left ventricular ejection fraction, 28.2% ± 7.8%; and heart rate at discharge, 84.3 ± 13.8 bpm) were included in the final analysis, including 292 and 584 patients with and without ivabradine treatment at discharge, respectively. No significant differences were observed in baseline characteristics between the two groups. At 1 year follow‐up, patients in the ivabradine group had significantly lower heart rates (77.6 ± 14.7 vs. 81.1 ± 16.3 bpm; P = 0.005) and lower HF severity symptoms (New York Heart Association Functional class, 2.1 ± 0.7 vs. 2.3 ± 0.9; P < 0.001) than those from the non‐ivabradine group. Ivabradine users had significantly lower risks of 1 year cardiovascular mortality (5.8 vs. 12.2 per 100‐person year; P = 0.003), all‐cause mortality (7.2 vs. 14.0 per 100‐person year; P = 0.003), and total HF rehospitalization (42.3 vs. 72.6 per 100‐person year; P < 0.001) than non‐ivabradine users. Following multivariate analysis, the predischarge prescription of ivabradine remained independently associated with lower 1 year all‐cause mortality (hazard ratio, 0.45; 95% confidence interval, 0.28–0.74; P = 0.002) and cardiovascular mortality (hazard ratio, 0.41; 95% confidence interval, 0.24–0.72; P = 0.002). Conclusions The current study findings suggest that ivabradine treatment is associated with reduced risks of cardiovascular mortality, all‐cause mortality, and HF rehospitalization within 1 year among patients with acute decompensated HFrEF in real‐world populations.

Abstract
Heart rate modulation therapy using ivabradine reduces mortality and morbidity in patients with systolic heart failure, whereas too reduced heart rate seems to worsen the clinical outcome. The optimal heart rate during heart rate modulation therapy remains unknown. Consecutive patients with left ventricular ejection fraction < 50% who received echocardiographic assessments and simultaneous heart rate measurements were retrospectively investigated. Theoretically ideal heart rate was calculated using a previously proposed formula: 93 - 0.13 × (deceleration time [msec]). Impacts of heart rate on the 1-year echocardiographic left ventricular reverse remodeling were compared among the three groups stratified by the heart rate status: optimal heart rate group (within 10 bpm of ideal heart rate), below-optimal heart rate group (< 10 bpm of ideal heart rate), and above-optimal heart rate group (> 10 bpm of ideal heart rate). A total of 75 patients (70 years old, 60 men) were included. There were no significant differences in the baseline characteristics among the three groups, except for the higher prevalence of tolvaptan use and higher plasma B-type natriuretic peptide level in the below-optimal heart rate group. Left ventricular end-diastolic diameter (from 55 to 54) and left ventricular ejection fraction (from 39 to 46) improved significantly only in the optimal heart rate group at 1-year follow-up (p < 0.05 for both). Optimal heart rate, which was calculated using a formula consisting of deceleration time, was associated with cardiac reverse remodeling in patients with systolic heart failure. Prospective study to investigate the implication of deceleration time-guided aggressive heart rate optimization is the next concern.

[PMID: 33470302 PMCID: PMC8133726 DOI: 10.36660/abc.20190090] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2019] [Revised: 09/12/2019] [Accepted: 10/23/2019] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Studies have shown that heart failure (HF) patients with heart rate (HR) < 70 bpm have had a better clinical outcome and lower morbidity and mortality compared with those with HR > 70 bpm. However, many HF patients maintain an elevated HR. OBJECTIVE To evaluate HR and the prescription of medications known to reduce mortality in HF patients attending an outpatient cardiology clinic. METHODS We consecutively evaluated patients seen in an outpatient cardiology clinic, aged older than 18 years, with diagnosis of HF and left ventricular ejection fraction (LVEF) < 45%. Patients with sinus rhythm were divided into two groups - HR ≤ 70 bpm (G1) and HR > 70 bpm (G2). The Student's t-test and the chi-square test were used in the statistical analysis, and a p-value < 0.05 was considered statistically significant. The SPSS software was used for the analyses. RESULTS A total of 212 consecutive patients were studied; 41 (19.3%) had atrial fibrillation or had a pacemaker implanted and were excluded from the analysis, yielding 171 patients. Mean age of patients was 63.80 ± 11.77 years, 59.6% were men, and mean LVEF 36.64±7.79%. The most prevalent HF etiology was ischemic (n=102; 59.6%), followed by Chagasic (n=17; 9.9%). One-hundred thirty-one patients (76.6%) were hypertensive and 63 (36.8%) diabetic. Regarding HR, 101 patients had a HR ≤70 bpm (59.1%) and 70 patients (40.93%) had a HR >70 bpm (G2). Mean HR of G1 and G2 was 61.5±5.3 bpm and 81.8±9.5 bpm, respectively (p<0.001). Almost all patients (98.8%) were receiving carvedilol, prescribed at a mean dose of 42.1±18.5 mg/day in G1 and 42.5±21.1mg/day in G2 (p=0.911). Digoxin was used in 5.9% of patients of G1 and 8.5% of G2 (p=0.510). Mean dose of digoxin in G1 and G2 was 0.19±0.1 mg/day and 0.19±0.06 mg/day, respectively (p=0,999). Most patients (87.7%) used angiotensin converting enzyme inhibitors (ACEI) or angiotensin II receptor blockers (ARB), and 56.7% used spironolactone. Mean dose of enalapril was 28.9±12.7 mg/day and mean dose of ARB was 87.8±29.8 mg/day. The doses of ACEI and ARB were adequate in most of patients. CONCLUSION The study revealed that HR of 40.9% of patients with HF was above 70 bpm, despite treatment with high doses of beta blockers. Further measures should be applied for HR control in HF patients who maintain an elevated rate despite adequate treatment with beta blocker. (Arq Bras Cardiol. 2020; 115(6):1063-1069).

Abstract
BACKGROUND Resting heart rate is a risk factor of adverse heart failure outcomes; however, studies have shown controversial results. This meta-analysis evaluates the association of resting heart rate with mortality and hospitalization and identifies factors influencing its effect. METHODS AND RESULTS We systematically searched electronic databases in February 2019 for studies published in 2005 or before that evaluated the resting heart rate as a primary predictor or covariate of multivariable models of mortality and/or hospitalization in adult ambulatory patients with heart failure. Random effects inverse variance meta-analyses were performed to calculate pooled hazard ratios. The Grading of Recommendations, Assessment, Development and Evaluation approach was used to assess evidence quality. Sixty-two studies on 163,445 patients proved eligible. Median population heart rate was 74 bpm (interquartile range 72-76 bpm). A 10-bpm increase was significantly associated with increased risk of all-cause mortality (hazard ratio 1.10, 95% confidence interval 1.08-1.13, high quality). Overall, subgroup analyses related to patient characteristics showed no changes to the effect estimate; however, there was a strongly positive interaction with age showing increasing risk of all-cause mortality per 10 bpm increase in heart rate. CONCLUSIONS High-quality evidence demonstrates increasing resting heart rate is a significant predictor of all-cause mortality in ambulatory patients with heart failure on optimal medical therapy, with consistent effect across most patient factors and an increased risk trending with older age.

Abstract
With worsening epidemiological trends for both the incidence and prevalence of type 2 diabetes mellitus (T2DM) and heart failure (HF) worldwide, it is critical to implement optimal prevention and treatment strategies for patients with these comorbidities, either alone or concomitantly. Several guidelines and consensus statements have recommended glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter type 2 inhibitors as add-ons to lifestyle interventions with or without metformin in those at high atherosclerotic cardiovascular disease risk. However, these recommendations are either silent about HF or fail to differentiate between the prevention of HF in those at risk versus the treatment of individuals with manifest HF. Furthermore, these documents do not differentiate among those with different HF phenotypes. This distinction, even though important, may not be critical for sodium-glucose cotransporter type 2 inhibitors in view of the consistent data for benefit for both atherosclerotic cardiovascular disease– and HF-related outcomes that have emerged from the regulatory-mandated cardiovascular outcome trials for all sodium-glucose cotransporter type 2 inhibitors and the recent DAPA-HF trial (Dapagliflozin in Patients with Heart Failure and Reduced Ejection Fraction)demonstrating the benefit of dapagliflozin on HF-related outcomes in patients with HF with reduced ejection fraction with or without T2DM. However, the distinction may be crucial for glucagon-like peptide-1 receptor agonists and other antihyperglycemic agents. Indeed, in several of the new statements, glucagon-like peptide-1 receptor agonists are suggested treatment not only for patients with T2DM and atherosclerotic cardiovascular disease, but also in those with manifest HF, despite a lack of evidence for the latter recommendation. Although glucagon-like peptide-1 receptor agonists may be appropriate to use in patients at risk for HF, mechanistic insights and observations from randomized trials suggest no clear benefit on HF-related outcomes and even uncertainty regarding the safety in those with HF with reduced ejection fraction. Conversely, theoretical rationales suggest that these agents may benefit patients with HF with preserved ejection fraction. Considering that millions of patients with T2DM have HF, these concerns have public health implications that necessitate the thoughtful use of these therapies. Achieving this aim will require dedicated trials with these drugs in both patients who have HF with reduced ejection fraction and HF with preserved ejection fraction with T2DM to assess their efficacy, safety, and risk-benefit profile.

Abstract
Background: Heart failure (HF) is increasing in prevalence worldwide. This systematic review was conducted to inform understanding of its humanistic and economic burden. Methods: Electronic databases (Embase, MEDLINE®, and Cochrane Library) were searched in May 2017. Data were extracted from studies reporting health-related quality of life (HRQoL) in 200 patients or more (published 2007–2017), or costs and resource use in 100 patients or more (published 2012–2017). Relevant HRQoL studies were those that used the 12- or 36-item Short-Form Health Surveys, EuroQol Group 5-dimensions measure of health status, Minnesota Living with Heart Failure Questionnaire or Kansas City Cardiomyopathy Questionnaire. Results: In total, 124 studies were identified: 54 for HRQoL and 71 for costs and resource use (Europe: 25/15; North America: 24/50; rest of world/multinational: 5/6). Overall, individuals with HF reported worse HRQoL than the general population and patients with other chronic diseases. Some evidence identified supports a correlation between increasing disease severity and worse HRQoL. Patients with HF incurred higher costs and resource use than the general population and patients with other chronic conditions. Inpatient care and hospitalizations were identified as major cost drivers in HF. Conclusions: Our findings indicate that patients with HF experience worse HRQoL and incur higher costs than individuals without HF or patients with other chronic diseases. Early treatment of HF and careful disease management to slow progression and to limit the requirement for hospital admission are likely to reduce both the humanistic burden and economic impact of HF.

ESC Heart Fail 2020; 7:3049-3058. [PMID: 32757485 PMCID: PMC7524238 DOI: 10.1002/ehf2.12931] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2020] [Revised: 07/12/2020] [Accepted: 07/20/2020] [Indexed: 11/25/2022] Open
Abstract
Aims Current guidelines recommend beta‐blocker therapy in chronic heart failure with reduced ejection fraction (HFrEF) titrated according to tolerated target dose. The efficiency of this strategy to obtain adequate heart rate (HR) control remains unclear in clinical practice. The aim of this study was to determine, in a real‐world setting, the proportion of HFrEF patients who fail to achieve beta‐blocker target doses, whether target doses of beta‐blockers have a relationship with the adequacy in reducing resting HR over time. Methods and results Beta‐blocker dose and resting HR of consecutive ambulatory patients with a diagnosis of HFrEF (ejection fraction ≤ 35%) in sinus rhythm were reviewed at the first outpatient contact in the Cleveland Clinic Health System from the year 2000 to 2015. Patients who did not receive beta‐blocker therapy, have congenital heart disease and hypertrophic cardiomyopathy, were not in sinus rhythm, or have a history of heart transplant were excluded. Patients were followed up until their last known visit at the Cleveland Clinic. Median resting HR was 71 b.p.m. [inter‐quartile range (IQR) 60–84 b.p.m.] in 8041 patients (median age 65; 68% male) with 67% on carvedilol, 32% on metoprolol succinate, and 1% on bisoprolol. In 3674 subjects (56%), resting HR was ≥70 b.p.m. At final follow‐up after a median of 21 months (IQR 0.1–7.2 years), resting HR was 72 b.p.m. (IQR 60–84 b.p.m.) in the subset of patients with persistently low ejection fraction ≤ 35%. HR ≥ 70 b.p.m. was observed in 55% of this group. Beta‐blocker target dose was achieved in 19%, 5%, and 15% of those receiving carvedilol, metoprolol succinate, and bisoprolol, respectively. In the subset of patients who experienced beta‐blocker up‐titration, reduced mortality or hospitalization due to heart failure was observed in patients who experienced the lowest HR after titration. Conclusions In our single‐centre experience, the majority of patients with chronic HFrEF treated with beta‐blocker therapy did not achieve target doses over time, and a substantial proportion had inadequate control of resting HR. There was no relationship between achieved beta‐blocker target dose and resting HR control.

ESC Heart Fail 2020; 7:2894-2903. [PMID: 32729678 PMCID: PMC7524131 DOI: 10.1002/ehf2.12899] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2020] [Revised: 06/03/2020] [Accepted: 06/24/2020] [Indexed: 11/12/2022] Open
Abstract
AIMS The aim of this study was to investigate whether the readmission of heart failure (HF) patients has decreased over time and how it differs among HF with preserved ejection fraction (EF) (HFpEF) vs. reduced EF (HFrEF) and mid-range EF (HFmrEF). METHODS AND RESULTS We evaluated HF patients index hospitalized from January 2004 to December 2011 in the Swedish Heart Failure Registry with 1 year follow-up. Outcome measures were the first occurring all-cause, cardiovascular (CV), and HF readmissions. A total of 20 877 HF patients (11 064 HFrEF, 4215 HFmrEF, and 5562 HFpEF) were included in the study. All-cause readmission was the highest in patients with HFpEF, whereas CV and HF readmissions were the highest in HFrEF. From 2004 to 2011, HF readmission rates within 6 months (from 22.3% to 17.3%, P = 0.003) and 1 year (from 27.7% to 23.4%, P = 0.019) in HFpEF declined, and the risk for 1 year HF readmission in HFpEF was reduced by 7% after adjusting for age and sex (P = 0.022). Likewise, risk factors for HF readmission in HFpEF changed. However, no significant changes were observed in all-cause or CV readmission rates in HFpEF, and no significant changes in cause-specific readmissions were observed in HFrEF. Time to the first readmission did not change significantly from 2004 to 2011, regardless of EF subgroup (all P-values > 0.05). CONCLUSIONS Declining temporal trend in HF readmission rates was found in HFpEF, but all-cause readmission still remained the highest in HFpEF vs. HFrEF and HFmrEF. More efforts are needed to reduce the non-HF-related readmission in patients with HFpEF.

The Effect of Ivabradine on the Human Atrial Myocardial Contractility in an In Vitro Study. Cardiol Res Pract 2019; 2019:7512318.

Abstract
Purpose Ivabradine has emerged as a new antiarrhythmic agent that could compete with the traditional ones, such as beta-blockers. This experimental study aims to ascertain whether ivabradine directly interferes with the myocardial contractility in an in vitro environment. Methods Myocardial tissues from the right atrial appendages of patients undergoing cardiac surgery were dissected to obtain 40 specimens from 20 patients (length: 3 mm), which were exposed to electrical impulses at a frequency of 75 bpm for 30 min to reach a steady state. Specimens were then categorised into four groups (each including five patients). The first group was the control, whereas the second, third, and fourth were treated with 60 nM, 200 nM, and 2 μM ivabradine, respectively. We assessed five different contraction parameters before and after a 15 min treatment and calculated their relative changes, which were then compared to the control group. Results Ivabradine has affected the force of contraction significantly in vitro (p=0.009). However, force of contraction decreased in both the control group (93.5 ± 4.7%) and the second group (94.1 ± 4.5%, p=0.8) and force of contraction remained unchanged in the third group (101.0 ± 4.1%, p=0.24) and increased significantly in the fourth group (108.9 ± 11.6%, p=0.008). There was no change in other contraction parameters, such as passive tension force (97.1 ± 5.1%, p=0.368), duration of contraction (99.1 ± 4.3%, p=0.816), time to peak (96.6 ± 3.0%, p=0.536), and time to relaxation (101.2 ± 7.0%, p=0.564). Conclusions Ivabradine did not interfere with the contractile behaviour of human atrial tissue when it was used in therapeutic dosages in vitro. However, it increased the contractility slightly, when it was used in supratherapeutic dosage.

Abstract
BACKGROUND Heart failure with reduced ejection fraction (HFrEF) is a progressive, chronic, and burdensome cardiovascular condition. It is associated with limiting symptoms, such as dyspnea and fatigue; a decline in functional capacity; and premature mortality and hospitalization. In heart failure (HF) management, heart rate is commonly assessed yet frequently overlooked as a modifiable risk factor and a predictor of mortality. An elevated heart rate increases myocardial demand and decreases diastolic filling time. Hospitalized patients with HFrEF who have a heart rate greater than 70 beats per minute at discharge were found to have lower survival rates. PURPOSE The aims of this study were to review the association between heart rate and clinical outcome in patients with HF and discuss the contribution of heart rate to HFrEF pathophysiology. Medications currently used to modulate heart rate in patients with HF are also reviewed. CONCLUSIONS In patients with HFrEF, an elevated heart rate contributes to HF progression, and it is both a prognostic and modifiable risk factor. Medications such as an evidence-based β-blockers, digoxin, and ivabradine are recommended for modulation of heart rate in patients with HFrEF. CLINICAL IMPLICATIONS Nurses play a pivotal role in managing HFrEF and must understand current evidence of the pathophysiology of elevated heart rate, risks, and management strategies. Early recognition of elevated heart rate and application of guideline-directed pharmacologic treatment for patients with HFrEF and an elevated heart rate remains key to improving patient outcomes.

Abstract
OBJECTIVE To investigate the no reflow risk factors after percutaneous coronary intervention in ST elevation myocardial infarction patients. METHOD Sample size, mean±standard deviation (SD) or frequencies (percent) of normal and no reflow groups were extracted from each study. RESULTS Of 27 retrospective and prospective studies, we found that increasing risks of no reflow were associated with advanced age, male, family history of coronary artery disease, smoking, diabetes mellitus, hypertension, delayed reperfusion, killip class ≥2, elevated blood glucose, increased creatinine, elevated creatine kinase (CK), higher heart rate, decreased left ventricular ejection fraction (LVEF), collateral flow ≤1, longer lesion length, multivessel disease, reference luminal diameter, initial thrombolysis in myocardial infarction (TIMI) flow, and high thrombus burden. Moreover, initial TIMI flow ≤1 and high thrombus burden had the greater impact on no reflow (OR95%CI=3.83 [2.77-5.29], p<0.0001 and 3.69 [2.39-5.68], p<0.0001, respectively). CONCLUSION Our meta-analysis reveals that initial TIMI flow ≤1 and high thrombus burden are the most impacted no reflow risk factors.

Abstract
BACKGROUND Hospitalization is an opportunity to optimize heart failure (HF) therapy. As optimal treatment for hospitalized HF patients in sinus rhythm with heart rate≥70bpm is unclear, we investigated the impact of combined beta-blocker (BB) and ivabradine versus BBs alone on short and longer term mortality and rehospitalization. METHODS AND RESULTS A retrospective analysis was performed on 370 hospitalized HF patients with heart rate≥70bpm (150 BB+ivabradine, 220 BB alone) in the Optimize Heart Failure Care Program in Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Russia, Ukraine, and Uzbekistan, from October 2015 to April 2016. RESULTS At 1month, 3months, 6months and 12months, there were fewer deaths, HF hospitalizations and overall hospitalizations in patients on BB+ivabradine vs BBs alone. At 12months, all-cause mortality or HF hospitalization was significantly lower with BB+ivabradine than BBs (adjusted hazard ratio [HR] 0.45 (95% confidence interval [CI] 0.32-0.64, P<0.0001). Significantly greater improvement was seen in quality of life (QOL) from admission to 12months with BB+ivabradine vs BBs alone (P=0.0001). With BB+ivabradine, significantly more patients achieved ≥50% target doses of BBs at 12months than on admission (82.0% vs 66.6%, P=0.0001), but the effect was non-significant with BBs alone. CONCLUSIONS Heart rate lowering therapy with BB+ivabradine started in hospitalized HF patients (heart rate≥70bpm) is associated with reduced overall mortality and re-hospitalization over the subsequent 12months. A prospective randomized trial is needed to confirm the advantages of this strategy.

Abstract
Although elevated resting heart rate is related to poor outcomes in heart failure (HF) with reduced ejection fraction, the association in HF with preserved ejection fraction (HFpEF) remains inconclusive. Therefore, we conducted a dose-response meta-analysis to examine the prognostic role of heart rate in patients with HFpEF.We searched PubMed and Embase databases until April 2017 and manually reviewed the reference lists of relevant literatures. Random effect models were used to pool the study-specific hazard ratio (HR) of outcomes, including all-cause death, cardiovascular death, and HF hospitalization.Six studies with 7 reports were finally included, totaling 14,054 patients with HFpEF. The summary HR (95% confidence interval [CI]) for every 10 beats/minute increment in heart rate was 1.04 (1.02-1.06) for all-cause death, 1.06 (1.02-1.10) for cardiovascular death, and 1.05 (1.01-1.08) for HF hospitalization. Subgroup analyses indicated that these positive relationships were significant in patients with sinus rhythm but not in those with atrial fibrillation. There was also evidence for nonlinear relationship of heart rate with each of the outcomes (All P for nonlinearity < .05).Higher heart rate in sinus rhythm is a risk factor for adverse outcomes in patients with HFpEF. Future trials are required to determine whether heart rate reduction may improve the prognosis of HFpEF.

Effect of renal function status on the prognostic value of heart rate in acute ischemic stroke patients. Atherosclerosis 2017; 263:1-6. [PMID: 28550709 DOI: 10.1016/j.atherosclerosis.2017.05.020] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2017] [Revised: 05/05/2017] [Accepted: 05/17/2017] [Indexed: 11/22/2022]
Abstract
BACKGROUND AND AIMS The association between heart rate and prognosis of ischemic stroke remains debatable, and whether renal function status influences the relationship between them is still not elucidated. METHODS A total of 3923 ischemic stroke patients were included in this prospective multicenter study from the China Antihypertensive Trial in Acute Ischemic Stroke (CATIS). The primary outcome was a combination of death and major disability (modified Rankin Scale score ≥3) at 3 months after stroke. Secondary outcomes were, separately, death and major disability. RESULTS The association between heart rate tertiles and primary outcome was appreciably modified by renal function status (pinteraction = 0.037). After multivariate adjustment, high heart rate was associated with increased risk of primary outcome in patients with abnormal renal function (odds ratio, 1.61; 95% confidence interval, 1.02-2.54; ptrend = 0.039) but not in patients with normal renal function (odds ratio, 0.96; 95% confidence interval, 0.75-1.23; ptrend = 0.741), when two extreme tertiles were compared. Each 10 bpm increase of heart rate was associated with 21% (95% CI: 1%-44%) increased risk of primary outcome, and a linear association between heart rate and risk of primary outcome was observed among patients with abnormal renal function (p for linearity = 0.002). CONCLUSIONS High heart rate may be merely a strong predictor of poor prognosis in acute ischemic stroke patients with abnormal renal function, suggesting that heart rate reduction should be applied to ischemic stroke patients with abnormal renal function to improve their prognosis.

Abstract
OBJECTIVE The introduction of the Hospital Readmission Reduction Program (HRRP) has led to renewed interest in developing strategies to reduce 30 day readmissions among patients with heart failure (HF). In this study, a model was developed to investigate whether the addition of ivabradine to a standard-of-care (SoC) treatment regimen for patients with HF would reduce HRRP penalties incurred by a hypothetical hospital with excess 30 day readmissions. RESEARCH DESIGN A model using a Monte Carlo simulation framework was developed. Model inputs included national hospital characteristics, hospital-specific characteristics, and the ivabradine treatment effect as quantified by a post hoc analysis of the Systolic Heart failure treatment with the If inhibitor ivabradine Trial (SHIFT). RESULTS The model computed an 83% reduction in HF readmission penalty payments in a hypothetical hospital with a readmission rate of 22.95% (excess readmission ratio = 1.056 over the national average readmission rate of 21.73%), translating into net savings of $44,016. A sensitivity analysis indicated that the readmission penalty is affected by the specific characteristics of the hospital, including the readmission rate, size of the ivabradine-eligible population, and ivabradine utilization. CONCLUSIONS The results of this study indicate that the addition of ivabradine to an SoC treatment regimen for patients with HF may lead to a reduction in the penalties incurred by hospitals under the HRRP. This highlights the role ivabradine can play as part of a wider effort to optimize the care of patients with HF.
