Management protocols for chronic heart failure in India

MicroRNA-30a-5p Promotes Chronic Heart Failure in Rats by Targeting Sirtuin-1 to Activate the Nuclear Factor-κB/NOD-Like Receptor 3 Signaling Pathway

OBJECTIVE

MicroRNA-30a-5p (miR-30a-5p) has been identified as a marker of heart failure; however, its functional mechanisms in chronic heart failure (CHF) remain unknown. We aim to investigate the role of miR-30a-5p targeting sirtuin-1 (SIRT1) in myocardial remodeling in CHF via the nuclear factor-κB/NOD-like receptor 3 (NF-κB/NLRP3) signaling pathway.

METHODS

CHF rat models were established using aortic coarctation. The expression of miR-30a-5p, SIRT1, and the NF-κB/NLRP3 signaling pathway-related factors in CHF rats was determined. The CHF rats were then respectively treated with altered miR-30a-5p or SIRT1 to explore their roles in cardiac function, myocardial function, inflammatory response, pathological changes, and cardiomyocyte apoptosis. The binding relation between miR-30a-5p and SIRT1 was confirmed.

RESULTS

MiR-30a-5p was upregulated whereas SIRT1 was downregulated in myocardial tissues of CHF rats. MiR-30a-5p inhibition or SIRT1 overexpression improved cardiac and myocardial function, and suppressed the inflammatory response, alleviated pathological changes and inhibited cardiomyocyte apoptosis in CHF rats. MiR-30a-5p targeted SIRT1 to regulate the NF-κB/NLRP3 signaling pathway. In CHF rats, downregulated miR-30a-5p and silenced SIRT1 could reverse the beneficial effects of downregulated miR-30a-5p.

CONCLUSION

Inhibited miR-30a-5p inhibits CHF progression via the SIRT1-mediated NF-κB/NLRP3 signaling pathway.

Impact of Mineralocorticoid Receptor Antagonists in the Treatment of Heart Failure: Targeting the Heart Failure Cascade

Epidemiological data from the Indian subcontinent on the burden of Heart failure (HF) is scarce. Mineralocorticoid receptor antagonists (MRAs) are usually used in the management of HF and hypertension. A consortium of experts reviewed and opined on the pathophysiological role of aldosterone in HF and its cascading effects on the heart in terms of cardiac fibrosis, cardiac hypertrophy, and remodeling, increased propensity to cause arrhythmias in addition to its effect on sodium and water retention. This expert opinion document highlights the various mechanisms of action of MRAs. It provides clinical experience and practice-based expert opinion on the use of spironolactone and eplerenone in patients with HF. The role of MRAs in diabetic patients with HF has also been profiled.

Noninvasive assessment of pulmonary congestion in heart failure: Need of the hour

Early pulmonary congestion detection and surveillance in acute heart failure patients can prevent decompensation, minimize hospitalizations, and improve prognosis. In India, the warm and wet types of HF are still the most common types and residual congestion at discharge is still a significant concern. Thus, there is an urgent need for a reliable and sensitive means of identifying residual and subclinical congestion. Two such monitoring systems are available and approved by US FDA. These include CardioMEMS HF System (Abbott, Sylmar, California) and ReDS System (Sensible Medical Innovations, Ltd., Nanya, Israel). CardioMEMS is a wireless pressure-sensitive implantable device, while ReDS is a wearable noninvasive device for measurement of the lung fluid and hence direct detection of PC. This review discusses the role of noninvasive assessment in PC monitoring in patients with heart failure and its implications from an Indian perspective.

The Potential Role of Torsemide in Optimizing Loop Diuretic Therapy for Heart Failure Patients

Heart failure is associated with an increased frequency of hospitalization, reduced life span, and greater risk to public health, thus posing a challenge. In India, torsemide is one of the commonly used loop diuretics for decongestion in heart failure. However, this use of torsemide, including its dosing, and up/down titration, is based on practical experience. Loop diuretic therapy for heart failure patients poses several dilemmas due to the lack of robust evidence based on which treatment decisions can be made. To guide physicians on the optimal use of torsemide in heart failure patients with or without renal impairment, a panel of expert cardiologists and nephrologists from India convened to develop this expert opinion document for the use of torsemide. This expert opinion on torsemide will pave the way for optimal management with loop diuretic therapy in real-world heart failure patients.

The National List of Essential Medicines of India 2022 (NLEM 2022): Tommy, Toe the Line

India recently released its fifth National List of Essential Medicines 2022 (NLEM 2022). A critical analysis of the list was performed and was compared with the WHO 22nd Model List of Essential Medicines published in 2021. The Standing National Committee, since its inception, have taken four years to finalise a list. The analysis identified that all the available formulations and strengths of the selected drugs are included in the list, which must be avoided. Furthermore, the antibacterial agents are not categorised as access, watch and reserve (AWaRe) and this list is not aligned with the national programs, standard treatment guidelines and nomenclature. There are a few factual errors and some typographic errors. These problems in the list need to be rectified immediately so that the document would be able to serve the community more effectively as a true model list.

Epidemiology of heart failure in rural Chhattisgarh, India

Background Cardiovascular diseases, including heart failure (HF), are leading causes of death and disability in India. However, most studies in India only include urban populations or rural regions with improved access and may not represent the poorest patients or regions. We studied the epidemiology of HF patients admitted to a secondary care hospital in rural Chhattisgarh, India. Methods We did a retrospective chart review of patients hospitalized with HF in 2018 to obtain their demographic data and risk factors for developing HF. We reviewed echocardio-grams to assign patients to their most probable HF category. Results We studied 88 HF patients with a mean age of 42 years including 55 (62.5%) women. The most common categories of HF were cardiomyopathy (36.8%), rheumatic heart disease (RHD; 25.3%) and right heart failure (RHF; 18.4%). Prior tuberculosis was more prevalent in patients with RHF compared with other types of HF (43.8% v. 13.9%). Conclusions HF patients in this study from rural central India were young and predominantly women. Cardiomyopathy, RHD and RHF due to past tuberculosis were common causes of HF in this population. Further studies are needed to expand upon these single centre findings to better understand the risk factors and outcomes of HF among the rural poor.

Management, clinical outcomes, and its predictors among heart failure patients admitted to tertiary care hospitals in Ethiopia: prospective observational study

BACKGROUND

Heart failure is a global pandemic, as it affects approximately 64.34 million people worldwide with a $346.17 billion global economic burden. The prevalence of heart failure has increased from 43.4 to 46.5% in the last 10 years in lower and middle-income countries. Most of the studies conducted in Ethiopia were retrospective cross-sectional, with limited study participants, and conducted in a single setting that commonly addresses the prevalence and pattern of heart failure rather than clinical outcome, associated factors, and specific management in different areas. Hence, this study aimed to assess management, clinical outcomes and their predictors among heart failure patients admitted to tertiary care hospitals in Ethiopia.

METHODS

A prospective observational study design was conducted on heart failure patients admitted at two tertiary care hospitals in Ethiopia from September 2020 to May 2021. Using semi-structured questionnaires relevant data were collected from patients' medical records and face-to-face interviewing. Data were analyzed using SPSS version 23.0. A multivariate Cox regression model was performed to identify independent predictors of 90-day all-cause mortality. Variables with P values < 0.05 were considered statistically significant.

RESULTS

Out of 283 patients enrolled in this study, 52.3% were male and the mean (± SD) age was 52.4 ± 17.9 years. The most common medications prescribed during hospitalization and discharge were diuretics (98.9% vs 95.6%), angiotensin I converting enzyme inhibitors/angiotensin II receptor blockers (48.8% vs 67.3%), and beta-blockers (46.6% vs 64.7%), respectively. In the present study, the 90-day all-cause mortality was 10.2%. Hypertension (HR = 3.7, 95% CI 1.2-11.6), cardiogenic shock (HR = 8.7, 95% CI 3.2-20.8), alcohol drinking (HR = 2.8, 95% CI 1.1-7.8), absence of angiotensin I converting enzyme inhibitors/angiotensin II receptor blockers (HR = 0.02, 95% CI 0.0-0.2), and reduced ejection fraction (HR = 1.5, 95% CI 1.1-3.8) were predictors of 90-day all-cause mortality.

CONCLUSION

High 90-day all-cause mortality was observed among heart failure patients in the present study. In the current study, the majority of heart failure patients were treated with diuretics. Alcohol drinking, hypertension, cardiogenic shock, reduced ejection fraction, and absence of angiotensin I converting enzyme inhibitors/angiotensin II receptor blockers drugs were predictors of poor treatment outcomes for whom restriction of alcohol consumption, early management of hypertension, reduced ejection fraction, cardiogenic shock, and providing angiotensin I converting enzyme inhibitors/angiotensin II receptor blockers drugs for all heart failure patients would be recommended to improve these poor treatment outcomes.

Quality of the Indian clinical practice guidelines for the management of cardiovascular conditions

To assess the quality of Indian clinical practice guidelines (CPG)s for the management of cardiovascular conditions, MEDLINE, Embase, Google Scholar and websites of relevant medical associations and government organisations were searched, from inception until August 2020, to identify Indian CPGs for the management of cardiovascular disease (CVD) conditions, produced in or between 2010 and 2019. Excluded were CPGs that were not specific to India, focused on alternative systems of medicine, of non-CVD conditions (even if they included a component of CVD), and those related to the electronic devices, cardiac biomarkers, or diagnostic procedures. Quality of the each included CPG was assessed using the AGREE II tool by four reviewers in duplicate, independently. Each AGREE II domain score and overall quality score was considered low (≤40%), moderate (40.1%-59.9%), and high (≥60%). Of the 23 CPGs included, six (26%) were reported to be adapted from other CPGs. Fourteen (61%) CPGs were produced by medical associations, six (26%) by individual authors and three (13%) by government agencies. Based on the AGREE II overall quality score, two (9%) CPGs were of high quality, four (17%) and seventeen (74%) CPGs were of moderate and low quality, respectively. Except for scope and purpose, and clarity of presentation all other domains were rated low. The quality of most Indian CPGs for managing CVD conditions assessed using the AGREE II tool was moderate-to-low. Combined efforts from different stakeholders are needed to develop, disseminate and implement high-quality CPGs while identifying and addressing barriers to their uptake to optimize patient care and improve outcomes.

Clinical Utility of Three-Dimensional Speckle-Tracking Echocardiography in Heart Failure

Heart failure (HF) is an extremely major health problem with gradually increasing incidence in developed and developing countries. HF may lead to cardiac remodeling; thus, advanced imaging techniques are required to comprehensively evaluate cardiac mechanics. Recently, three-dimensional speckle-tracking echocardiography (3D-STE) has been developed as a novel imaging technology that is based on the three-dimensional speckle-tracking on the full volume three-dimensional datasets. Three-dimensional speckle-tracking echocardiography allows a more accurate evaluation of global and regional myocardial performance, assessment of cardiac mechanics, detection of subclinical cardiac dysfunction, and prediction of adverse clinical events in a variety of cardiovascular diseases. Therefore, this review summarizes the clinical usefulness of 3D-STE in patients with HF.

Medikamentöse Therapie der HFrEF – früher Nutzen von Synergien und individuelle Konzepte

Die aktuellen Leitlinien zur Pharmakotherapie der Herzinsuffizienz mit reduzierter Pumpfunktion empfehlen den frühzeitigen und möglichst simultanen Beginn mit einem Betablocker (BB), SGLT2-Inhibitor (SGLT2i), Mineralokortikoidrezeptor-Antagonisten (MRA) und ACE-Hemmer (ACEi) bzw. alternativ einem Angiotensin-Rezeptor-Neprilysin-Inhibitor (ARNI). Dabei wird die Sequenz des Therapiestarts der empfohlenen Wirkstoffklassen und deren Erweiterung und Dosissteigerung im Verlauf unter Berücksichtigung der individuellen Patientenmerkmale und Komorbiditäten bewusst dem behandelnden Arzt überlassen. Somit wird das bisherige Stufenschema mit einer sequenziellen Initiierung der verschiedenen Wirkstoffklassen verlassen, da diese primär auf der Historie der zugrunde liegenden klinischen Endpunktstudien basieren und nicht den frühzeitigen und synergistischen prognoseverbessernden Effekt der Wirkstoffklassen berücksichtigen. Die Empfehlung zur Dosissteigerung auf die in den klinischen Studien verwendeten Zieldosen von BB, SGLT2i, MRA und ACEi bzw. ARNI bleibt aber erhalten. Die Erweiterung um weitere Wirkstoffklassen sollte in Abhängigkeit von Komorbiditäten, klinischen Parametern, Progress der Herzinsuffizienz und Evidenzlage aus klinischen Studien erfolgen.

Effectiveness of self-care educational programme on clinical outcomes and self-care behaviour among heart failure peoples-A randomized controlled trial: Study protocol

AIM

To evaluate the effectiveness of a self-care education programme on clinical outcomes, self-care behaviour and knowledge on heart failure (HF) among peoples with HF.

DESIGN

Randomized controlled trial.

METHODS

The participants (N = 160) will be randomly assigned (1:1) to the intervention and the control arms using block randomization. The participants assigned to the intervention arm will receive educational intervention on HF self-care comprising video-assisted teaching with teach-back technique, tailored teaching at discharge and a guide on self-care followed by telephonic calls and text messages after discharge for 6 months along with standard care. The participants in the control arm will receive only a guide on self-care with standard care. The clinical outcomes such as health-related quality of life, hospital readmissions, N-terminal pro-brain natriuretic peptide levels, symptom perception, functional status, left ventricular ejection fraction, Seattle HF score, self-care behaviour and knowledge on HF will be measured at the baseline, after 1 and 6 months of the intervention.

DISCUSSION

Several studies conducted on self-care education interventions have shown positive effects, whereas few studies have shown no effect on the people outcomes. Providing the printed self-care guide alone may not improve behaviour associated with self-care and clinical outcomes. These peoples need continuous reinforcement on self-care. If this self-care educational intervention shows beneficial effects, it will contribute to the clinical practice and improve clinical outcomes.

IMPACT

This research will contribute to the evidence on the effectiveness of an educational intervention on self-care among peoples with HF. The results would assist the nurses caring for peoples with HF. They can also implement this intervention for improving the peoples' self-care behaviour.

TRIAL REGISTRATION

The trial is registered with the Clinical Trial Registry India and the reference ID number CTRI/2019/10/021724.

Efficacy and Safety of Ivabradine Once-Daily Prolonged-Release versus Twice-Daily Immediate-Release Formulation in Patients with Stable Chronic Heart Failure with Systolic Dysfunction: A Randomized, Double-Blind, Phase 3 Non-Inferiority (PROFICIENT) Study

Introduction

Dosing frequency is an important factor influencing medication compliance in patients with heart failure (HF), which in turn is imperative in achieving the desired therapeutic outcome. Here we assessed the efficacy and safety of ivabradine prolonged-release (PR) once-daily (test) vs. ivabradine immediate-release (IR) twice-daily (reference) formulations in patients with stable chronic HF with systolic dysfunction.

Methods

Patients with sinus rhythm and heart rate (HR) ≥ 50 bpm, left ventricular ejection fraction ≤ 40% (HF with reduced ejection fraction), on guideline-based standard care, receiving a stable dose of ivabradine IR 5/7.5 mg twice daily for ≥ 1 month were enrolled in this randomized, double-blind, phase 3 non-inferiority study. Patients were randomly assigned 1:1 to ivabradine PR (10 mg/15 mg) based on the ivabradine IR dosage or continued ivabradine IR (5 mg/7.5 mg). The primary endpoint was change in resting ECG HR from baseline to the end of 3 months, assessed by 12-lead ECG. Safety assessments and 24-h Holter HR monitoring (in a subgroup of patients) were also performed. Non-inferiority was concluded if the upper limit of the 95% CI of the difference between the test and reference was less than the margin of 6.5 bpm in the per-protocol set.

Results

A total of 169 out of 180 randomized patients (93.9%) completed the study (PR = 84; IR = 85). The least-square mean (standard error [SE]) for change in HR from baseline to 3 months was 0.76 (1.188; 95% CI −1.59:3.11) in ivabradine PR vs. ivabradine IR, which was within the pre-specified margin of 6.5 bpm, confirming the non-inferiority of ivabradine PR. The change from baseline to 3 months was comparable between the treatment groups for 24-h Holter ECG monitoring (p = 0.3701), mean HR awake (p = 0.3423), and mean HR asleep (p = 0.1501). Thirty-nine treatment-emergent adverse events (TEAEs) were reported; the majority in both groups were of mild or moderate severity and were subsequently resolved. Seven serious adverse events were reported (ivabradine PR = 2; ivabradine IR = 5), of which one was fatal (ivabradine IR group). The bradycardia events reported were comparable between groups.

Conclusion

Ivabradine PR was found to be non-inferior to ivabradine IR in the management of patients with stable CHF, with a comparable safety profile. Once-daily ivabradine PR effectively maintained the HR in patients shifted from the ivabradine IR twice-daily regimen, and thus may aid in improving treatment compliance.

Consensus and development of document for management of stabilized acute decompensated heart failure with reduced ejection fraction in India

Aim

Ensuring adherence to guideline-directed medical therapy (GDMT) is an effective strategy to reduce mortality and readmission rates for heart failure (HF). Use of a checklist is one of the best tools to ensure GDMT. The aim was to develop a consensus document with a robust checklist for stabilized acute decompensated HF patients with reduced ejection fraction. While there are multiple checklists available, an India-specific checklist that is easy to fill and validated by regional and national subject matter experts (SMEs) is required.

Methodology

A total of 25 Cardiology SMEs who consented to participate from India discussed data from literature, current evidence, international guidelines and practical experiences in two national and four regional meetings.

Results

Recommendations included HF management, treatment optimization, and patient education. The checklist should be filled at four time points- (a) transition from intensive care unit to ward, (b) at discharge, (c) 1st follow-up and (d) subsequent follow-up. The checklist is the responsibility of the consultant or the treating physician which can be delegated to a junior resident or a trained HF nurse.

Conclusion

This checklist will ensure GDMT, simplify transition of care and can be used by all doctors across India. Institutions, associations, and societies should recommend this checklist for adaptability in public and private hospital. Hospital administrations should roll out policy for adoption of checklist by ensuring patient files have the checklist at the time of discharge and encourage practice of filling it diligently during follow-up visits.

Consensus document: management of heart failure in type 2 diabetes mellitus

Type 2 diabetes mellitus (T2DM) is a known predisposing factor for heart failure (HF). The growing burden of these two conditions and their impact on health of the individual and on society in general needs urgent attention from the health care professionals. Availability of multiple treatment choices for managing T2DM and HF may make therapeutic decisions more complex for clinicians. Recent cardiovascular outcome trials of antidiabetic drugs have added very robust evidence to effectively manage subjects with this dual condition. This consensus statement provides the prevalence trends and the impact of this dual burden on patients. In addition, it concisely narrates the types of HF, the different treatment algorithms, and recommendations for physicians to comprehensively manage such patients.

Effect of Baduanjin exercise on patients with chronic heart failure: protocol for a systematic review and meta-analysis

INTRODUCTION

Chronic heart failure (CHF) is defined when the heart is unable to pump sufficiently to maintain blood flow to meet the body's needs, and it is caused by various cardiopulmonary diseases. CHF is a common, lifelong and costly condition. Baduanjin exercise (BDJE), a form of traditional Chinese regimen, has been integrated into China's clinical practice in recent years and has shown promise in cardiac rehabilitation of CHF patients. However, the efficacy of BDJE on CHF patients has not been fully statistically evaluated. In this study, we aim to systematically examine the efficacy and safety of BDJE for CHF patients.

METHODS AND ANALYSIS

A systematic literature search for articles up to October 2018 will be conducted in the following databases: Web of Science, Pubmed, Embase, Cochrane Library, Chinese Science and Technology Periodicals Database, Chinese National Knowledge Infrastructure and Wanfang Database. We will also search other resources. Randomised controlled trials that examined treatment of CHF patients with BDJE will be selected. Results will be analysed by assessing the quality of life of patients using the Minnesota living with heart failure questionnaire, and measurement of distance walked over a span of 6 min in the 6 min walk test. RevMan 5.3 will be used for data synthesis, sensitivity analysis, meta-regression analysis, subgroup analysis and risk of bias assessment. A funnel plot will be developed to evaluate reporting bias, and Begg and Egger tests will be used to assess funnel plot symmetries. Grading of recommendations assessment, development and evaluation system will be utilised to assess the quality of evidence.

ETHICS AND DISSEMINATION

This systematic review will be submitted to a peer-reviewed journal.

Efficacy of ivabradine for heart failure: A protocol for a systematic review of randomized controlled trial

BACKGROUND

Previous clinical trials have reported that ivabradine can effectively treat heart failure (HF). However, no systematic review has explored its efficacy and safety for HF. This systematic review will aim to evaluate the efficacy and safety of ivabradine for the treatment of patients with HF.

METHODS

We will search the literature from the following electronic databases from inception to the January 31, 2019: Cochrane Central Register of Controlled Trials, EMBASE, MEDILINE, Web of Science, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine Database, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, VIP Information, and Wanfang Data. All randomized controlled trials (RCTs) of ivabradine for HF will be fully considered for inclusion without any restrictions. Additionally, grey literature including clinical trial registries, dissertations, and reference lists of included studies, conference abstracts will also be searched. Two researchers will review these literatures, extract data, and assess risk of bias of included RCTs separately. Data will be pooled by either fixed-effects model or random-effects model, and meta-analysis will be conducted if it is appropriate.

RESULTS

The primary outcome is all-cause mortality. The secondary outcomes comprise of change in body weight, urine output, change in serum sodium, and all adverse events.

CONCLUSIONS

The results of this study will summary provide up-to-dated evidence for assessing the efficacy and safety of ivabradine for HF.

ETHICS AND DISSEMINATION

It is not necessary to acquire ethical approval for this systematic review, because no individual patient data will be used in this study. The results of this systematic review will be published through peer-reviewed journals.
