Intravenous ferric carboxymaltose for iron repletion following acute heart failure in patients with and without diabetes: a subgroup analysis of the randomized AFFIRM-AHF trial.

BACKGROUND: In AFFIRM-AHF, treatment of iron deficiency with intravenous ferric carboxymaltose (FCM) reduced the risk of heart failure (HF) hospitalization and improved quality of life (QoL) vs placebo in patients stabilized following an acute HF (AHF) episode, with no effect on cardiovascular (CV) death. Diabetes and iron deficiency frequently accompany AHF. This post hoc analysis explored the effects of diabetes on outcomes in AFFIRM-AHF patients. METHODS: Patients were stratified by diabetes yes/no at baseline. The effects of FCM vs placebo on primary (total HF hospitalizations and CV death) and secondary (total CV hospitalizations and CV death; CV death; total HF hospitalizations; time to first HF hospitalization or CV death; and days lost due to HF hospitalizations or CV death) endpoints at Week 52 and change vs baseline in disease-specific QoL (12-item Kansas City Cardiomyopathy Questionnaire [KCCQ-12]) at Week 24 were assessed by subgroup. For each endpoint, the interaction between diabetes status and treatment outcome was explored. RESULTS: Of 1108 AFFIRM-AHF patients, 475 (FCM: 231; placebo: 244) had diabetes and 633 (FCM: 327; placebo: 306) did not have diabetes. Patients with diabetes were more commonly male (61.5% vs 50.9%), with a higher frequency of ischemic HF etiology (57.9% vs 39.0%), prior HF history (77.7% vs 66.5%), and comorbidities (including previous myocardial infarction [49.3% vs 32.9%] and chronic kidney disease [51.4% vs 32.4%]) than those without diabetes. The annualized event rate/100 patient-years with FCM vs placebo for the primary endpoint was 66.9 vs 80.9 in patients with diabetes (rate ratio [RR]: 0.83, 95% CI 0.58-1.81) and 51.3 vs 66.9 in patients without diabetes (RR: 0.77, 95% CI 0.55-1.07), with no significant interaction between diabetes status and treatment effect (pinteraction = 0.76). Similar findings were observed for secondary outcomes. Change from baseline in KCCQ-12 overall summary score was numerically greater with FCM vs placebo at almost all time points in both subgroups, with no interaction between diabetes and treatment effect at Week 24. CONCLUSIONS: The clinical and QoL benefits observed with intravenous FCM in patients with iron deficiency following stabilization from an AHF episode are independent of diabetes status.

Antidepressants and the Risk of Cardiovascular Events in Elderly Affected by Cardiovascular Disease: A Real-Life Investigation From Italy.

PURPOSE: The purpose of this study was to assess the possible relation between use of antidepressant (AD) drugs, that is, tricyclic ADs, selective serotonin reuptake inhibitors (SSRIs), and atypical ADs (AAs), and the risk of hospitalization for cardiovascular (CV) events among older patients with previous CV diseases. METHODS: A nested case-control study was carried out among patients aged 65 years and older from 5 Italian health care territorial units who were discharged for CV disease during 2008 to 2010. The cohort was composed by 344,747 individuals, and of these, 97,739 (28%) experienced hospital admission for CV events (myocardial infarction, arrhythmia, stroke, heart failure) during follow-up (until 2014) and were included as cases. Up to 5 controls were randomly selected and matched to each. A conditional logistic regression was fitted to estimate the risk of CV events associated with ADs past or current use. A within-patient comparison was performed by the case-crossover design to account the effect of depression. FINDINGS: Current users of SSRIs and AAs were at increased risk of CV events with odds ratios of 1.25 (95% confidence interval, 1.21-1.29) and 1.31 (1.25-1.37), respectively. An increased risk of arrhythmia and stroke was associated with current use of SSRIs and AAs, whereas an increased risk of heart failure was detected with current use of any ADs. The results were confirmed by the case-crossover approach. IMPLICATIONS: Evidence that AD use is associated with an increased risk of CV events in accordance with specific mechanisms of action among older people with CV disease was added by this study.

Frailty in patients with heart failure.

The importance of frailty in heart failure (HF) patients has been increasingly recognized because of its high prevalence and its significantly adverse impact on prognosis and quality of life. Due to the impact of frailty on both prognosis and treatment of HF patients, all patients with HF, regardless of their chronological age, should be evaluated for the presence of, or the risk for developing frailty. However, although several instruments are available, there is still no consensus as to which is the best method to assess frailty in patients with HF. Therefore, a validated and easy to apply instrument to assess frailty in HF patients in daily practice is warranted.

Assess frailty but avoid frailtyism.

The assessment of frailty in heart failure patients can help clinicians to build a tailored care plan, aimed at improving the selection of patients likely to benefit from one treatment vs. another, thereby improving outcomes. Although progress has been made in the 'operationalization' of frailty assessment, there is still the need to provide an improved instrument to assess frailty that is easy, quick and at the same time predictive within the setting of a busy clinical practice. Using such an ideal instrument, clinicians would be able to optimize the use of limited health care resources and avoid what has been termed 'frailtyism'. This term, similar to ageism, can be defined as prejudice or discrimination based on the presence of frailty.

Care plans for the older heart failure patient.

Heart failure (HF) professionals are managing an older population with multiple, often interconnected comorbidities. The average age of the HF patient has increased substantially and many have a number of comorbidities. For the older HF patient, diligent planning of care has the potential to reduce hospitalization, improve quality of life and mortality; nevertheless, this vital component is often overlooked. Frailty, cachexia, sarcopenia, and cognitive impairment are all common in the older HF patient and require special care considerations. Many older HF patients live for many years with troublesome symptoms that could be better addressed through the incorporation of a palliative approach to care. Effective care plans can help patients maximize their health potential through both lifestyle and pharmacological interventions. However, current evidence remains scarce on what constitutes an optimal plan, therefore further studies are urgently needed. We review the care that could be implemented for the complex older HF patient with comorbidities.

Who approves/pays for additional monitoring?

Major considerations in the provision of healthcare are availability, affordability, accessibility, and appropriateness, especially in the setting of heart failure where disease burden is growing, developments have been rapid and newer biomarkers, diagnostic and imaging techniques, monitoring systems, devices, procedures, and drugs have all been developed in a relatively short period of time. Many monitoring and diagnostic systems have been developed but the disproportionate cost of conducting trials of their effectiveness has limited their uptake. There are added complexities, in that the utilization of doctors for the supervision of the monitoring results may be optimal in one setting and not in another because of differences in the characteristics of organization of healthcare provision, making even interpretation of the trials we have had, still difficult to interpret. New technologies are continuously changing the approach to healthcare and will reshape the structure of the healthcare systems in the future. Mobile technologies can empower patients and carers by giving them more control over their health and social care needs and reducing their dependence on healthcare professionals for monitoring their health, but a significant problem is the integration of the multitude of monitored parameters with clinical data and the recognition of intervention thresholds. Digital technology can help, but we need to prove its cost/efficacy and how it will be paid for. Governments in many European countries and worldwide are trying to establish frameworks that promote the convergence of standards and regulations for telemedicine solutions and yet simultaneously health authorities are closely scrutinizing healthcare spending, with the objective of reducing and optimizing expenditure in the provision of health services. There are multiple factors to be considered for the reimbursement models associated with the implementation of physiological monitoring yet it remains a challenge in cash-strapped health systems.

Drug therapy in elderly heart failure patients.

Although heart failure (HF) is considered as a cardiogeriatric syndrome, elderly and very elderly patients are under-represented in the vast majority of clinical trials investigating novel drugs and therapies in this population. The homoeostatic systems of elderly subjects are very fragile, and the management of HF accompanied by numerous comorbidities requires a holistic approach towards the patient, with special emphasis not only on psychosomatic problems but also on the individual (including social) needs of each particular patient, along with the support for the family and/or caregivers. In this article, we summarize current evidence regarding pharmacotherapy of elderly patients with HF and summarize the clinical problems occurring in this population.

NSAIDs utilization for musculoskeletal indications in elderly patients with cerebro/cardiovascular disease.

OBJECTIVES: To describe NSAID utilization for musculoskeletal conditions in a large cohort of Italian elderly with cerebro/cardiovascular disease, a population in which NSAIDs should be generally avoided due to the prothrombotic potential. METHODS: Administrative data from five Italian geographic areas were analyzed. Patients aged ≥ 65 with a cerebro/cardiovascular event recorded between 2008 and 2011 (cohort entry) were selected. Prescription NSAIDs reimbursed for musculoskeletal conditions and dispensed during 1 year follow-up were retrieved to describe (i) prevalence of use, (ii) average amount of defined daily doses of NSAIDs claimed by users per day of follow-up, and (iii) distribution of the received daily dose (RDD) among patients with ≥ 2 dispensings. Among new users, i.e., patients without NSAID dispensings during 2 years before cohort entry, the first dispensed NSAID molecule was observed. RESULTS: Overall, 511,989 patients were selected. Across the five geographic areas, prevalence of use ranged from 48 to 21% and average consumption ranged between 30 and 67 DDD/1000 users/day. Around 10% of patients in the overall cohort had a RDD > 1. Nimesulide (9.6%) and diclofenac (7.5%) had the highest prevalence of use. The most consumed NSAIDs were nimesulide and coxibs with 10.6 and 7.5 DDD/1000 users/day, respectively. Among new users recruited in 2011, 30% had diclofenac or a coxibs as the first prescription. CONCLUSIONS: NSAID use was common in the study cohort, particularly in central-southern areas. In contrast with current recommendations, coxibs and diclofenac were among the most prescribed active principles, even in new users. Interventions to promote appropriateness of use are warranted.

Exposure to statins is associated to fracture risk reduction in elderly people with cardiovascular disease: evidence from the AIFA-I-GrADE observational project.

PURPOSE: Conflicting findings were observed from clinical trials and observational studies evaluating the association between the use of statins and the risk of fracture. A case-control study nested into a cohort of elderly patients on treatment with statins for cardiovascular secondary prevention was performed on this issue. METHODS: The cohort was formed by 13 875 individuals aged ≥65 years from several Italian health units receiving statins after hospital discharge for cardiovascular outcomes. From this cohort, 964 patients who experienced fracture were identified (i.e., cases). Up to five controls were randomly selected for each case from the underlying cohort. Conditional logistic regression was used to model the risk of fracture associated with adherence to statins, which was measured from the proportion of days covered (PDC) by treatment. A set of sensitivity analyses was performed in order to account for sources of systematic uncertainty. RESULTS: Compared with patients with low adherence (PDC ≤ 40%), those on intermediate (PDC 41-80%) and high (PDC > 80%) adherence exhibited a risk reduction of 21% (95% confidence interval 6% to 23%) and 25% (7% to 40%). Similar effects were observed among patients younger and older than 80 years, as well as among men, while there was no evidence that adherence to statins affected the risk of fracture among women. Sensitivity analyses revealed that the associations were consistent and robust. CONCLUSIONS: Use of statins for secondary cardiovascular prevention is associated with fracture risk reduction in elderly people. Further studies are required to better clarify the statin-fracture association in postmenopausal women. Copyright © 2017 John Wiley & Sons, Ltd.

Need for streamlined use of DPP-4 inhibitors in the treatment of type 2 diabetes.

Regulatory agencies request an assessment of cardiovascular safety for all "new" oral anti-diabetic drugs in order to avoid possible negative effects on cardiovascular events. Dipeptidyl peptidase 4 inhibitors have emerged as a new therapeutic alternative for the treatment of type 2 diabetes mellitus, but the several large post-marketing clinical trials have shown only a modest effect in glycaemic control and, more importantly, a neutral effect on total and cardiovascular events. Conversely a recent trial with empagliflozin, a sodium-glucose co-transporter 2 inhibitor, has shown significant effect on overall and cardiovascular mortality. Although glycaemic control is an important aspect of diabetes management, the results of the EMPA-REG outcome trial suggest that it is possible to develop anti-diabetic drugs that may exert an overall beneficial effect beyond the mere improvement of glycaemic control. While the regulatory hurdles should not be increased, there is the need for evaluation of the net clinical impact and cost effectiveness of all anti-diabetic agents. Therefore, a better collaboration among all stakeholders is needed in order to develop studies with endpoints that will be both clinically meaningful including appropriate follow-up, and economically relevant in patients with type 2 diabetes mellitus.

Role of Coronary Microvascular Dysfunction in Takotsubo Cardiomyopathy.

Takotsubo cardiomyopathy (TTC) is a relatively frequent acute cardiac condition, but its pathogenesis has not been established as yet. Since the first descriptions of TTC, microvascular dysfunction has been advocated as a possible pathophysiological mechanism underlying the left ventricular wall motion abnormalities that characterize the syndrome. Several noninvasive and invasive methods have confirmed the involvement of coronary microvascular abnormalities in the pathogenesis of TTC, but whether microvascular dysfunction is the primary cause or a secondary phenomenon is still debated. The greater prevalence of TTC among postmenopausal women, along with the relationship identified between physical and emotional triggers and other "neuro-cardiac" mechanisms, suggest that increased microvascular reactivity, possibly sympathetically mediated, may play a pathogenic role in susceptible individuals. This review critically evaluates the possible role of microvascular dysfunction in the development of TTC.

Pharmacological Management of Chronic Stable Angina: Focus on Ranolazine.

Percutaneous coronary intervention and anti-anginal medications have similar prognostic effectiveness in patients with chronic stable angina. The choice of optimal medical therapy for the management of chronic angina is of pivotal importance in patients with stable ischemic heart disease. The most commonly used anti-anginal agents have demonstrated equivalent efficacy in improving patient reported ischemic symptoms and quantitative exercise parameters. With regards to mortality, beta-blockers are beneficial only in the setting of depressed left ventricular systolic function after a recent myocardial infarction. Recent evidence suggests the lack of any benefit of beta-blockers in patients with preserved systolic function, even in the setting of prior myocardial infarction.Ranolazine is a non-haemodynamic anti-anginal agent. It is effective as adjunctive therapy in patients with chronic stable angina whose symptoms are un-adequately controlled by conventional treatment. The clinical development program of ranolazine has shown that the drug improves exercise performance, decreases angina and use of sublingual nitrates, compared to placebo. Ranolazine is well tolerated with neutral effect on haemodynamics. Besides its role in chronic stable angina, ranolazine has the potential for development in a number of other cardiovascular and non-cardiovascular conditions in the future.

Membrane lipid rafts and estrogenic signalling: a functional role in the modulation of cell homeostasis.

It has become widely accepted that along with their ability to directly regulate gene expression, estrogens also influence cell signalling and cell function via rapid membrane-initiated events. Many of these signalling processes are dependent on estrogen receptors (ER) localized to the plasma membrane. However, the mechanisms by which ER are able to trigger cell signalling when targeted to the membrane surface have to be determined yet. Lipid rafts seem to be essential for the plasma membrane localization of ER and play a critical role in their membrane-initiated effects. In this review, we briefly recapitulate the localization and function of ER in different cell types and mostly discuss the possible role of lipid rafts in this context. Further studies in this field may disclose new promising therapeutic avenues by the disruption of lipid rafts in those diseases in which membrane ER activation has been demonstrated to play a pathogenetic role.

Comparison of the pharmacodynamic effects of ranolazine versus amlodipine on platelet reactivity in stable patients with coronary artery disease treated with dual antiplatelet therapy : The ROMAN (RanOlazine vs. aMlodipine on platelet reactivity in stable patients with CAD treated with dual ANtiplatelet therapy) study.

Amlodipine, commonly used for relief of ischemic symptoms in coronary artery disease (CAD), may affect clopidogrel-induced antiplatelet effects. It remains unknown if ranolazine, an antianginal drug that constitutes a pharmacologic alternative to calcium channel blockade, interferes with clopidogrel-induced antiplatelet effects. The aim of the ROMAN study was to compare the pharmacodynamic effects of ranolazine versus amlodipine on platelet reactivity in clopidogrel treated patients with CAD. A prospective, randomized, cross-over, open-label study conducted in a total of 210 CAD patients on aspirin (100 mg/q.d.) and clopidogrel (75 mg/q.d.) 1 month following percutaneous coronary intervention. Patients were randomly assigned to amlodipine (10 mg p.d., n = 105) or ranolazine (750 mg b.i.d., n = 105) for 15 days, and after a 1-week wash-out period, crossed-over treatment for 15 days. P2Y12 reaction units (PRU) were assessed at baseline and after each treatment sequence. High on-treatment platelet reactivity (HPR) was defined as a PRU > 208. Amlodipine was associated with higher PRU than ranolazine (182 ± 75 vs. 167 ± 64, p = 0.028). As compared with baseline, PRU increased significantly after treatment with amlodipine (p = 0.018), but was not different after ranolazine therapy (p = 0.871). Changes in platelet reactivity following amlodipine therapy appeared to depend on baseline HPR status, as PRU levels significantly increased only among HPR subjects. In stable CAD patients treated with dual antiplatelet therapy after PCI, concomitant treatment with amlodipine, but not ranolazine, interferes with clopidogrel-induced antiplatelet effects.

The effect of peroxynitrite decomposition catalyst MnTBAP on aldehyde dehydrogenase-2 nitration by organic nitrates: role in nitrate tolerance.

Bioconversion of glyceryl trinitrate (GTN) into nitric oxide (NO) by aldehyde dehydrogenase-2 (ALDH-2) is a crucial mechanism which drives vasodilatory and antiplatelet effect of organic nitrates in vitro and in vivo. Oxidative stress generated by overproduction of free radical species, mostly superoxide anions and NO-derived peroxynitrite, has been suggested to play a pivotal role in the development of nitrate tolerance, though the mechanism still remains unclear. Here we studied the free radical-dependent impairment of ALDH-2 in platelets as well as vascular tissues undergoing organic nitrate ester tolerance and potential benefit when using the selective peroxynitrite decomposition catalyst Mn(III) tetrakis (4-Benzoic acid) porphyrin (MnTBAP). Washed human platelets were made tolerant to nitrates via incubation with GTN for 4h. This was expressed by attenuation of platelet aggregation induced by thrombin (40U/mL), an effect accompanied by GTN-related induction of cGMP levels in platelets undergoing thrombin-induced aggregation. Both effects were associated to attenuated GTN-induced nitrite formation in platelets supernatants and to prominent nitration of ALDH-2, the GTN to NO metabolizing enzyme, suggesting that GTN tolerance was associated to reduced NO formation via impairment of ALDH-2. These effects were all antagonized by co-incubation of platelets with MnTBAP, which restored GTN-induced responses in tolerant platelets. Comparable effect was found under in in vivo settings. Indeed, MnTBAP (10mg/kg, i.p.) significantly restored the hypotensive effect of bolus injection of GTN in rats made tolerants to organic nitrates via chronic administration of isosorbide-5-mononitrate (IS-5-MN), thus confirming the role of peroxynitrite overproduction in the development of tolerance to vascular responses induced by organic nitrates. In conclusion, oxidative stress subsequent to prolonged use of organic nitrates, which occurs via nitration of ALDH-2, represents a key event in GTN tolerance, an effect counteracted both in vitro and in vivo by novel peroxynitrite decomposition catalyst.

Pharmacodynamic comparison of pitavastatin versus atorvastatin on platelet reactivity in patients with coronary artery disease treated with dual antiplatelet therapy.

BACKGROUND: Levels of platelet reactivity in patients on dual antiplatelet therapy (DAPT) can be influenced by concomitant treatment with statins. We verified if the pharmacodynamic effects of CYP3A4-metabolized statins (atorvastatin) and non-CYP3A4-metabolized statins (pitavastatin) differ in patients with coronary artery disease (CAD) treated with DAPT. METHODS AND RESULTS: A total of 155 CAD patients receiving DAPT (clopidogrel 75mg plus aspirin 100mg) entered the PORTO trial. Patients were randomly assigned to atorvastatin (20mg day) or pitavastatin (4mg day) for 30 days, and then switched to the other drug for 30 days. Platelet reactivity was expressed as VerifyNow P2Y12 platelet response units (PRU) before and after each 30-day treatment period. High platelet reactivity was defined as PRU >208. As compared with pretreatment (192±49), PRU was significantly higher after 30-day atorvastatin (210±56; P=0.003), but was unchanged after 30-day pitavastatin (199±47 PRU, NS). In the 48 patients with PRU >208 at baseline (232±44), PRU increased significantly after 30-day atorvastatin (258±41, P=0.004), but not after 30-day pitavastatin (237±43, NS). In the 107 patients with PRU <208 at baseline (174±52), PRU did not change significantly with respect to baseline either after 30-day atorvastatin (188±61, NS) or after 30-day pitavastatin (181±59, NS). CONCLUSIONS: Pitavastatin, a non-CYP3A4-metabolized statin, does not affect clopidogrel's response as compared with atorvastatin in patients who are borderline or poor responders to DAPT.

Precision Cardiology: Phenotype-targeted Therapies for HFmrEF and HFpEF.

Heart failure with mid-range ejection fraction (HFmrEF) and preserved ejection fraction (HFpEF) represent over half of heart failure cases but lack proven effective therapies beyond sodium-glucose cotransporter 2 inhibitor and diuretics. HFmrEF and HFpEF are heterogeneous conditions requiring precision phenotyping to enable tailored therapies. This review covers concepts on precision medicine approaches for HFmrEF and HFpEF. Areas discussed include HFmrEF mechanisms, anti-inflammatory and antifibrotic treatments for obesity-related HFpEF, If inhibition for HFpEF with atrial fibrillation, and mineralocorticoid receptor antagonism for chronic kidney disease-HFpEF. Incorporating precision phenotyping and matched interventions in HFmrEF and HFpEF trials will further advance therapy compared to blanket approaches.

The role of multimorbidity in patients with heart failure across the left ventricular ejection fraction spectrum: Data from the Swedish Heart Failure Registry.

AIMS: The aim of this analysis was to provide data on the overall comorbidity burden, both cardiovascular (CV) and non-CV, in a large real-world heart failure (HF) population across the ejection fraction (EF). METHODS AND RESULTS: Patients with HF from the Swedish HF Registry between 2000 and 2021 were included. Of 91 463 patients (median age 76 years [interquartile range 67-82]), 98% had at least one among the 17 explored comorbidities (94% at least one CV and 85% at least one non-CV comorbidity). All comorbidities, except for coronary artery disease (CAD), were more frequent in HF with preserved EF (HFpEF). Patients with multiple comorbidities were older, more likely female, inpatients, with HFpEF, worse New York Heart Association class and higher N-terminal pro-B-type natriuretic peptide levels. In a multivariable Cox model, 12 comorbidities were independently associated with a higher risk of death from any cause. The highest risk was associated with dementia (hazard ratio [HR] 1.55, 95% confidence interval [CI] 1.45-1.65), chronic kidney disease (HR 1.37, 95% CI 1.34-1.41), chronic obstructive pulmonary disease (HR 1.32, 95% CI 1.28-1.35). Obesity was associated with a lower risk of all-cause death (HR 0.81, 95% CI 0.79-0.84). CAD and valvular heart disease were associated with a higher risk of all-cause and CV mortality, but not non-CV mortality, whereas cancer and musculo-skeletal disease increased the risk of non-CV mortality. A significant interaction with EF was observed for several comorbidities. Occurrence of CV and non-CV outcomes was related to the number of CV and non-CV comorbidities, respectively. CONCLUSION: The burden of both CV and non-CV comorbidities was high in HF regardless of EF, but overall higher in HFpEF. Multimorbidity was associated with a high risk of death with a different burden on CV or non-CV outcomes.

Multidisciplinary care of peripartum heart failure: A scientific statement of the Heart Failure Association of the ESC.

Heart failure is the most common cardiovascular complication during pregnancy and the postpartum period. It is associated with increased risk of maternal morbidity and mortality as well as potentially life-threatening foetal pathology. Management of heart failure in pregnancy requires expert knowledge of cardiovascular disease as well as obstetrics which underscores the importance of multidisciplinary cardio-obstetrics teams in order to optimize diagnosis, treatment and outcome. This includes counselling of women at risk before and during the course of pregnancy in order to strengthen the relationship between medical specialists and patients, as well as to allow patient-centred delivery of care and improve quality of life.

How to tackle therapeutic inertia in heart failure with reduced ejection fraction. A scientific statement of the Heart Failure Association of the ESC.

Guideline-directed medical therapy (GDMT) in patients with heart failure and reduced ejection fraction (HFrEF) reduces morbidity and mortality, but its implementation is often poor in daily clinical practice. Barriers to implementation include clinical and organizational factors that might contribute to clinical inertia, i.e. avoidance/delay of recommended treatment initiation/optimization. The spectrum of strategies that might be applied to foster GDMT implementation is wide, and involves the organizational set-up of heart failure care pathways, tailored drug initiation/optimization strategies increasing the chance of successful implementation, digital tools/telehealth interventions, educational activities and strategies targeting patient/physician awareness, and use of quality registries. This scientific statement by the Heart Failure Association of the ESC provides an overview of the current state of GDMT implementation in HFrEF, clinical and organizational barriers to implementation, and aims at suggesting a comprehensive framework on how to overcome clinical inertia and ultimately improve implementation of GDMT in HFrEF based on up-to-date evidence.
