The recently published guideline of the European Society of Cardiology for the management of patients with ventricular arrhythmias and the prevention of sudden cardiac death updates the guideline from 2015. Overall, the current guideline is characterised by a great practical relevance: Illustrative algorithms, e.g., for diagnostic evaluation, and tables make the guideline a user-friendly reference book. In the diagnostic evaluation and risk stratification of sudden cardiac death, cardiac magnetic resonance imaging and genetic testing are significantly upgraded. In long-term management, the optimal treatment of the underlying disease is essential, and recommendations for heart failure therapy are adapted to current international guidelines. Catheter ablation is upgraded especially for patients with ischaemic cardiomyopathy and recurrent ventricular tachycardia, as well as in the management of symptomatic idiopathic ventricular arrhythmias. Criteria for primary prophylactic defibrillator therapy remain controversial. In the context of dilated cardiomyopathy, imaging, genetic testing, and clinical factors are given special weight in addition to left ventricular function. Additionally, revised diagnostic criteria for a large number of primary electrical diseases are provided.

This clinical consensus statement reviews the use of inotropic support in patients with advanced heart failure. The current guidelines only support use of inotropes in the setting of acute decompensated heart failure with evidence of organ malperfusion or shock. However, inotropic support may be reasonable in other patients with advanced heart failure without acute severe decompensation. The clinical evidence supporting use of inotropes in these situations is reviewed. Particularly, patients with persistent congestion, systemic hypoperfusion, or advanced heart failure with need for palliation, and specific situations relevant to implantation of left ventricular assist devices or heart transplantation are discussed. Traditional and novel drugs with inotropic effects are discussed and use of guideline-directed therapy during inotropic support is reviewed. Finally, home inotropic therapy is described, and palliative care and end-of-life aspects are reviewed in relation to management of ongoing inotropic support (including guidance for maintenance and weaning of chronic inotropic therapy support).

Creation of an algorithm that includes the most important parameters (history, clinical parameters, and anamnesis) that can be linked to heart failure, helping general practitioners in recognizing heart failure in an early stage and in a better follow-up of the patients.
The algorithm was created using a consensus-based Delphi panel technique with fifteen general practitioners and seven cardiologists from Belgium. The method comprises three iterations with general statements on diagnosis, referral and treatment, and follow-up. Consensus was obtained for the majority of statements related to diagnosis, referral, and follow-up, whereas a lack of consensus was seen for treatment statements. Based on the statements with good and perfect consensus, an algorithm for general practitioners was assembled, helping them in diagnoses and follow-up of heart failure patients. The diagnosis should be based on three essential pillars, i.e. medical history, anamnesis and clinical examination. In case of suspected heart failure, blood analysis, including the measurement of NT-proBNP levels, can already be performed by the general practitioner followed by referral to the cardiologist who is then responsible for proper diagnosis and initiation of treatment. Afterwards, a multidisciplinary health care process between the cardiologist and the general practitioner is crucial with an important role for the general practitioner who has a key role in the up-titration of heart failure medication, down-titration of the dose of diuretics and to assure drug compliance.
Based on the consensus levels of statements in a Delphi panel setting, an algorithm is created to help general practitioners in the diagnosis and follow-up of heart failure patients.

The prognosis of patients with idiopathic dilated cardiomyopathy (DCM) has improved remarkably in recent decades with guideline-directed medical therapy. Left ventricular (LV) reverse remodeling (LVRR) is one of the major therapeutic goals. Whether myocardial fibrosis or inflammation would reverse associated with LVRR remains unknown.
A total of 157 prospectively enrolled patients with DCM underwent baseline and follow-up cardiovascular magnetic resonance examinations with a median interval of 13.7 months (interquartile range, 12.2-18.5 months). LVRR was defined as an absolute increase in LV ejection fraction of >10% to the final value of ≥35% and a relative decrease in LV end-diastolic volume of >10%. Statistical analyses were performed using paired t test and student t test, logistic regression analysis, and linear regression analysis.
Forty-eight (31%) patients reached LVRR. At baseline, younger age, worse New York Heart Association class, new-onset heart failure, lower LV ejection fraction, absence of late gadolinium enhancement, lower myocardial T2, and extracellular volume were significant predictors of LVRR. During the follow-up, patients with and without LVRR both showed a significant decrease of myocardial native T1 (LVRR: [baseline] 1303.0±43.6 ms; [follow-up] 1244.7±51.8 ms; without LVRR: [baseline] 1308.5±80.5 ms; [follow-up] 1287.6±74.9 ms, both P<0.001), matrix and cellular volumes while no significant difference was observed in T2 or extracellular volume values after treatment.
In patients with idiopathic DCM, the absence of late gadolinium enhancement, lower T2, and extracellular volume values at baseline are significant predictors of LVRR. The myocardial T1, matrix, and cell volume decrease significantly in patients with LVRR after guideline-directed medical therapy.

Inotropes aim at increasing cardiac output by enhancing cardiac contractility. They constitute the third pharmacological pillar in the treatment of patients with decompensated heart failure, the other two being diuretics and vasodilators. Three classes of parenterally administered inotropes are currently indicated for decompensated heart failure, (i) the beta adrenergic agonists, including dopamine and dobutamine and also the catecholamines epinephrine and norepinephrine, (ii) the phosphodiesterase III inhibitor milrinone and (iii) the calcium sensitizer levosimendan. These three families of drugs share some pharmacologic traits, but differ profoundly in many of their pleiotropic effects. Identifying the patients in need of inotropic support and selecting the proper inotrope in each case remain challenging. The present consensus, derived by a panel meeting of experts from 21 countries, aims at addressing this very issue in the setting of both acute and advanced heart failure.

Prescriber adherence to guideline-recommended medication in patients with heart failure (HF) in clinical practice is suboptimal. We analyzed how evolving guideline recommendations influenced medication profiles after a first HF hospitalization. We extracted medication profiles from the Dutch PHARMO Database Network for 22,476 patients with a diagnosis of HF at hospital discharge between 2001 and 2015. The percentage of patients prescribed the combination of a beta-blocker (BB) and an angiotensin-converting-enzyme inhibitor (ACEI) or angiotensin-receptor blocker (ARB) increased from 24 to approximately 45% within this 15-year period. The percentage of patients who also used a mineralocorticoid-receptor antagonist (MRA) reached approximately 20%. The probability of being prescribed these combinations decreased with increasing age. As a consequence of the policy change in the ESC guideline 2001, the use of BB increased from less than 40% in 2001 to about 70% by 2015. The percentage of patients prescribed an ACEI and/or an ARB, an MRA, or a diuretic was about stable, at respectively 63%, 37%, and 82%. Although the 2012 ESC guideline also advised MRA in the New York Heart Association (NYHA) class II, there was no increase in MRA prescriptions. Compliance with the ESC guidelines varied for the individual recommendations. Remarkably, there was no significant increase in MRA prescriptions. At the same time, developments were demonstrated, which were not instigated by the guidelines, like the shift from ACEI to ARB. Although the exact HF classification of our patients was unknown, given a relatively stable case mix, our data provide insight into \"real-world\" pharmacological management.

This study sought to summarize all available evidence on sex differences in adverse drug reactions (ADRs) to heart failure (HF) medication.
Women are more likely to experience ADRs than men, and these reactions may negatively affect women\'s immediate and long-term health. HF in particular is associated with increased ADR risk because of the high number of comorbidities and older age. However, little is known about ADRs in women with HF who are treated with guideline-recommended drugs.
A systematic search of PubMed and EMBASE was performed to collect all available information on ADRs to angiotensin-converting enzyme inhibitors, β-blockers, angiotensin II receptor blockers, mineralocorticoid receptor antagonists, ivabradine, and digoxin in both women and men with HF.
The search identified 155 eligible records, of which only 11 (7%) reported ADR data for women and men separately. Sex-stratified reporting of ADRs did not increase over the last decades. Six of the 11 studies did not report sex differences. Three studies reported a higher risk of angiotensin-converting enzyme inhibitor-related ADRs in women, 1 study showed higher digoxin-related mortality risk for women, and 1 study reported a higher risk of mineralocorticoid receptor antagonist-related ADRs in men. No sex differences in ADRs were reported for angiotensin II receptor blockers and β-blockers. Sex-stratified data were not available for ivabradine.
These results underline the scarcity of ADR data stratified by sex. The study investigators call for a change in standard scientific practice toward reporting of ADR data for women and men separately.
