Clinical trials update from European Society of Cardiology meeting 2008: TIME‐CHF,BACH, BEAUTIFUL,GISSI‐HF,and HOME‐HF

This article provides information and a commentary on trials relevant to the pathophysiology, prevention and treatment of heart failure presented at the European Society of Cardiology meeting which was held in Munich, Germany from 30th August to 3rd September 2008. Unpublished reports should be considered as preliminary, as analyses may change in the final publication. The TIME‐CHF study failed to show that BNP guided therapy was superior to usual care in patients with heart failure. The BACH study suggested that a new biomarker, MR‐proANP, was as good as BNP for the diagnosis of heart failure in patients presenting with breathlessness. Ivabradine failed to reduce the incidence of cardiovascular events in patients with coronary artery disease and left ventricular systolic dysfunction in the BEAUTIFUL study, but patients with higher heart rates might have benefited. In GISSI‐HF, n–3 PUFA reduced mortality and cardiovascular hospitalisation by a small amount compared to placebo in patients with chronic heart failure, but rosuvastatin had no effect on clinical outcomes. In the HOME‐HF study, telemonitoring support failed to reduce the time to first re‐hospitalisation or death, or days alive and out of hospital, compared with usual care.     

Clinical trials update from Heart Rhythm 2008 and Heart Failure 2008: ATHENA, URGENT, INH study, HEART and CK-1827452

This article provides information and a commentary on trials relevant to the pathophysiology, prevention and treatment of heart failure, presented at the Heart Rhythm Society meeting in San Francisco, USA and the Heart Failure Association meeting of the European Society of Cardiology which was held in Milan, Italy in June 2008. Unpublished reports should be considered as preliminary data, as analyses may change in the final publication. The ATHENA study showed that dronedarone reduced the incidence of the composite outcome of cardiovascular hospitalisation or death, in patients with atrial fibrillation or flutter, 29% of whom had a history of heart failure, compared with placebo. The URGENT study demonstrated that treatment of acute heart failure with standard therapy, including intravenous diuretics and nitrates, leads to a rapid resolution of breathlessness in the sitting position but that orthopnoea often persists. The INH study showed that a disease management programme could reduce mortality compared to usual care but not hospitalisation rates. The HEART study failed to recruit its planned number of patients, although it is the largest randomised trial of revascularisation in heart failure reported to date. At a median follow-up of 5 years no difference in mortality was observed but the study lacked power to provide a conclusive result. The selective myosin activator CK-1827452 produced a concentration dependent increase in systolic ejection time, stroke volume and fractional shortening in patients with heart failure compared to placebo.     

Clinical trials update from the American College of Cardiology Meeting 2011: STICH, NorthStar, TARGET, and EVEREST II

This article provides information and a commentary on key trials relevant to the pathophysiology, prevention, and treatment of heart failure (HF) presented at the annual American College of Cardiology meeting held in New Orleans in 2011. Unpublished reports should be considered as preliminary, since analyses may change in the final publication. The STICH trial failed to show a benefit of revascularization on all‐cause mortality in patients with HF and coronary artery disease; however, cardiovascular deaths were reduced compared with medical therapy alone. Results from the NorthStar study suggest that patients with clinically stable systolic HF, who are on optimal medical therapy, including those with elevated amino‐terminal B‐type natriuretic peptide levels, may not benefit from long‐term follow‐up in an HF clinic. Results from the TARGET study demonstrate that targeted left ventricular lead placement using speckle tracking echocardiography is feasible in patients undergoing implantation of a cardiac resynchronization therapy device and is associated with an enhanced response. Two‐year follow‐up data from EVEREST II show that although a catheter‐based mitral valve repair procedure using the MitraClip^® system was less effective at reducing mitral regurgitation than conventional surgery, similar improvements in clinical outcomes were observed with fewer short‐term adverse events.     

Clinical trials update from the American Heart Association 2007: CORONA, RethinQ, MASCOT, AF-CHF, HART, MASTER, POISE and stem cell therapy

This article provides information and a commentary on trials relevant to the pathophysiology, prevention and treatment of heart failure, presented at the American Heart Association 2007. These should be considered as preliminary data, as analyses may change in the final publication. Rosuvastatin did not reduce mortality compared to placebo in patients with heart failure and left ventricular systolic dysfunction due to ischaemic heart disease in the CORONA study. Results of RethinQ provide equivocal evidence of benefit from CRT in patients with heart failure, echocardiographic dyssynchrony and QRS interval <130 ms. In the MASCOT study, the addition of atrial overdrive pacing did not reduce the incidence of permanent atrial fibrillation in patients receiving CRT. The AF-CHF study failed to show a benefit of rhythm control over rate control in patients with heart failure and atrial fibrillation. Self-management skills training and education had no benefit on the combined outcome of death or heart failure hospitalisation, compared with education alone in heart failure patients in the HART study. Microvolt T-wave alternans testing failed to identify patients at increased risk of life-threatening ventricular arrhythmias in the MASTER study. POISE suggests that initiating metoprolol therapy shortly prior to non-cardiac surgery increases the risk of hypotension, stroke and death, despite reducing the risk of myocardial infarction. Three trials of stem cell therapy in post-MI patients gave conflicting results.     

Clinical trials update from the American Heart Association meeting 2010: EMPHASIS-HF, RAFT, TIM-HF, Tele-HF, ASCEND-HF, ROCKET-AF, and PROTECT

This article provides information and a commentary on key trials relevant to the pathophysiology, prevention, and treatment of heart failure presented at the annual meeting of the American Heart Association held in Chicago in 2010. Unpublished reports should be considered as preliminary, since analyses may change in the final publication. In patients with mild heart failure (HF), EMPHASIS-HF showed that the addition of eplerenone to standard therapy was well tolerated and reduced both the risk of death and hospitalization. The addition of cardiac resynchronization therapy to implantable cardioverter defibrillator (ICD) therapy reduced the incidence of all-cause mortality and HF hospitalizations in patients with NYHA class II-III HF compared with ICD alone in RAFT. Telemonitoring failed to improve outcome compared with a high standard of conventional care in patients with chronic HF (TIM-HF study) and a telephone-based interactive voice response system failed to improve outcome in patients recently hospitalized for HF (Tele-HF study). ASCEND-HF suggested that nesiritide was ineffective but safe in patients with acute decompensated HF. ROCKET-AF suggests that the factor-Xa inhibitor rivaroxaban may be as effective as warfarin in patients with atrial fibrillation. The PROTECT study provided more data to suggest that amino-terminal B-type natriuretic peptide guided therapy may be beneficial in patients with left ventricular systolic dysfunction.     

Clinical trials update from Heart Rhythm 2007 and Heart Failure 2007: CARISMA, PREPARE, DAVID II, SAVE-PACE, PROTECT and AREA-IN-CHF

This article provides information and a commentary on trials relevant to the pathophysiology, prevention and treatment of heart failure, presented at Heart Rhythm 2007 organised by the Heart Rhythm Society which was held in Denver, USA and Heart Failure 2007 organised by the Heart Failure Association of the European Society of Cardiology which was held in Hamburg, Germany. Unpublished reports should be considered as preliminary data, as analyses may change in the final publication. The CARISMA study suggests that non-invasive screening tests may help to identify post-MI patients who may benefit from ICD therapy. Data from the PREPARE study show that more conservative ICD programming can reduce morbidity at the cost of an increased risk of arrhythmic syncope. DAVID II indicates that atrial pacing may be a safe alternative to ventricular back-up pacing in patients with left ventricular dysfunction and standard indications for an ICD. The incidence of persistent atrial fibrillation in patients with sinus node disease in SAVE-PACE was reduced by dual chamber minimal ventricular pacing compared to conventional dual chamber pacing. The pilot phase of the PROTECT studies confirmed 30 mg as the dose of the selective A1 adenosine receptor antagonist KW-3902 to be used in pivotal studies. AREA-IN-CHF failed to show a beneficial effect of canrenone on LV volumes compared to placebo however some beneficial effects on secondary clinical endpoints were observed.     

Clinical trials update from the European Society of Cardiology Meeting 2010: SHIFT, PEARL-HF, STAR-heart, and HEBE-III

This article provides information and a commentary on key trials relevant to the pathophysiology, prevention, and treatment of heart failure (HF) presented at the annual meeting of the European Society of Cardiology held in Stockholm in 2010. Unpublished reports should be considered as preliminary, since analyses may change in the final publication. The SHIFT study supports the use of ivabradine in patients with HF due to left ventricular systolic dysfunction and resting sinus rhythm rate ≥70 b.p.m. despite treatment with beta-blockers or where beta-blockers are contra-indicated. Results from PEARL-HF suggest that the potassium binding polymer RLY5016 may be useful for both prevention and treatment of hyperkalaemia in HF patients with or without concomitant chronic kidney disease. The STAR-heart study provides encouraging observational data about the potential for intracoronary stem cell transplantation in patients with HF. Results from HEBE-III showed no effect of erythropoietin on ejection fraction measured 6 weeks post-MI; although there were fewer cardiovascular events in patients assigned to erythropoietin, the study was too small to provide conclusive evidence of effect.     

Clinical trials update from the Heart Failure Society of America and the American Heart Association meetings in 2008: SADHART-CHF,COMPARE, MOMENTUM,thyroid hormone analogue study,HF-ACTION,I-PRESERVE, β-interferon study,BACH, and ATHENA

This article provides information and a commentary on trials relevant to the pathophysiology, prevention, and treatment of heart failure presented at the Heart Failure Society of America and the American Heart Association meetings in 2008. Unpublished reports should be considered as preliminary, as analyses may change in the final publication. (i) SADHART-CHF showed no difference in outcome for heart failure patients with depression treated with sertraline compared with placebo. (ii) A controlled release carvedilol formulation showed similar LV haemodynamic effects to the standard carvedilol formulation in the COMPARE study. (iii) A post hoc analysis of the MOMENTUM study suggested that patients with less severe heart failure may be more likely to benefit from a continuous aortic flow augmentation device. (iv) A thyroid hormone analogue was poorly tolerated in patients with heart failure. (v) HF-ACTION showed that exercise training is safe and offers modest clinical benefits in patients with heart failure. (vi) Irbesartan failed to improve outcomes in patients with preserved ejection fraction in the I-PRESERVE study. (vii) A phase II study of beta-interferon administration in patients with dilated cardiomyopathy showed encouraging results. (viii) The BACH study showed that mid-regional pro-adrenomedullin was more accurate than BNP or NT-proBNP at predicting outcome at 90 days in patients with acute heart failure. (ix) A secondary analysis from ATHENA showed a reduction in cardiovascular hospitalizations and strokes for patients with atrial fibrillation receiving dronedarone compared with placebo.     

Clinical trials update from the American College of Cardiology meeting 2010: DOSE,ASPIRE, CONNECT,STICH, STOP‐AF,CABANA, RACE II,EVEREST II,ACCORD, and NAVIGATOR

This article provides information and a commentary on trials relevant to the pathophysiology, prevention and treatment of heart failure presented at the annual meeting of the American College of Cardiology held in March 2010. Unpublished reports should be considered as preliminary, since analyses may change in the final publication. Results from DOSE suggest that giving diuretics using a high‐dose, bolus strategy may be better than using lower doses or a continuous infusion for patients with acute decompensated heart failure. In the ASPIRE study, addition of aliskiren to standard therapy failed to attenuate left ventricular remodelling in post‐MI patients and was associated with more adverse events. In CONNECT, remote monitoring reduced the time from CRT‐D‐ or ICD‐detected events to clinical decision and this was associated with fewer clinic visits and shorter hospitalizations. An analysis from STICH testing the effects of surgical ventricular reconstruction showed no benefit in the sub‐group of patients who achieved a greater reduction in LV volume. STOP‐AF and CABANA did not provide convincing evidence of the effectiveness or safety of catheter ablation for the treatment of AF. RACE II suggests that lenient heart rate control might be as effective as strict rate control in patients with permanent atrial fibrillation. In EVEREST II, a catheter‐based mitral valve repair procedure using the MitraClip® system had similar efficacy to traditional surgery but with fewer short‐term adverse effects. Valsartan reduced progression to diabetes in patients with impaired glucose tolerance but had no effect on cardiovascular events in NAVIGATOR. In ACCORD, strict blood pressure control failed to reduce the risk of overall cardiovascular events in high‐risk diabetic patients.     

Clinical trials update from the European Society of Cardiology Meeting 2009: AAA,RELY, PROTECT,ACTIVE‐I,European CRT survey,German pre‐SCD II registry,and MADIT‐CRT

This article provides information and a commentary on trials relevant to the pathophysiology, prevention, and treatment of heart failure presented at the annual meeting of the European Society of Cardiology held in Barcelona in 2009. The AAA study does not support the routine use of aspirin for the prevention of vascular events in patients with asymptomatic atherosclerosis. RELY suggests that dabigatran may be more effective than warfarin for the prevention of stroke in patients with atrial fibrillation. Rolofylline was not superior to placebo in improving outcomes in patients with acute heart failure enrolled in the PROTECT study, but dyspnoea was improved. Data from ACTIVE‐I suggest that irbesartan does not provide additional therapeutic benefit in patients with atrial fibrillation who are well controlled on current therapy. The European cardiac resynchronization therapy (CRT) survey provides interesting epidemiological data on current CRT device usage. The German pre‐SCD II registry identified a low prevalence of patients with a reduced ejection fraction following myocardial infarction. Implantation of CRT‐D rather than an implantable cardioverter defibrillator in patients with mild heart failure and QRS ≥130 ms reduced the risk of hospitalization for heart failure in MADIT‐CRT; mortality was similarly low with each device.     

Clinical trials update from the European Society of Cardiology Heart Failure meeting 2011: TEHAF, WHICH, CARVIVA, and atrial fibrillation in GISSI-HF and EMPHASIS-HF

This article provides information and a commentary on key trials relevant to the pathophysiology, prevention, and treatment of heart failure (HF) presented at the European Society of Cardiology Heart Failure meeting held in Gothenburg, Sweden in May 2011. Unpublished reports should be considered as preliminary, since analyses may change in the final publication. In the TEHAF study, use of the Health Buddy^® monitoring system failed to reduce the number of HF admissions compared with usual care but a subgroup of patients with more recently diagnosed HF may have benefited. In the WHICH study, some reductions in the rate of hospital stay were observed in patients who underwent a nurse‐led home‐based intervention programme following a hospital admission for an acute HF exacerbation, compared with patients who were followed in a specialized outpatient clinic. Results from CARVIVA‐HF suggest that ivabradine alone or in combination with carvedilol is safe and effective for improving exercise capacity and quality of life in HF patients on optimized angiotensin‐converting enzyme inhibitor therapy. In the GISSI‐HF study there was no difference in atrial fibrillation (AF) occurrence between the n‐3 polyunsaturated fatty acids and placebo groups. In EMPHASIS‐HF the incidence of new onset AF or flutter was reduced in patients with mild HF randomized to eplerenone compared with placebo.     

Clinical trials update from the European Society of Cardiology heart failure meeting 2009: CHANCE,B‐Convinced,CHAT, CIBIS‐ELD,and Signal‐HF

This paper provides information and a commentary on trials relevant to the pathophysiology, prevention, and treatment of heart failure presented at the annual meeting of the Heart Failure Association of the European Society of Cardiology held in Nice. The CHANCE study showed a substantial reduction in morbidity and mortality in a randomized controlled trial (RCT) of a multidisciplinary management programme for patients with chronic heart failure in Russia. Data from the B‐Convinced study, also an RCT, suggest that continuation of beta‐blocker (BB) therapy in patients hospitalized with worsening heart failure may be associated with improved outcomes when compared with treatment discontinuation. The CHAT study suggests that telephone support can improve prognosis in heart failure patients living in remote rural locations. CIBIS‐ELD showed that titration of BBs to target doses in older patients with heart failure is more difficult; but tolerance levels were similar for bisoprolol and carvedilol. Signal‐HF randomized elderly heart failure patients to treatment guided by NT‐proBNP levels or usual care, and showed no effect of NT‐proBNP‐guided treatment on outcomes.     

Clinical trials update from the American College of Cardiology 2009: ADMIRE‐HF,PRIMA, STICH,REVERSE, IRIS,partial ventricular support,FIX‐HF‐5, vagal stimulation,REVIVAL‐3, pre‐RELAX‐AHF,ACTIVE‐A,HF‐ACTION,JUPITER, AURORA,and OMEGA

This article provides information and a commentary on trials relevant to the pathophysiology, prevention and treatment of heart failure presented at the American College of Cardiology meeting in 2009. Unpublished reports should be considered as preliminary, since analyses may change in the final publication. ¹²³I‐mIBG myocardial scintigraphy was a good predictor of mortality in patients with heart failure in ADMIRE‐HF. In PRIMA, use of individualized target NT‐proBNP levels failed to improve outcomes compared with usual care in patients hospitalized with symptomatic heart failure. In the STICH trial, additional ventricular reconstruction surgery failed to improve outcomes in patients with ischaemic heart failure undergoing CABG. Cardiac resynchronization therapy may modify disease progression in patients with mild heart failure, according to data from REVERSE. Implantation of a defibrillator early after MI in high‐risk patients in the IRIS study failed to improve outcomes compared with usual care. Cardiac contractility modulation showed some beneficial effects on symptoms and exercise capacity in the unblinded FIX‐HF‐5 study. Data from pre‐RELAX‐AHF show that relaxin may have potential as a treatment for acute heart failure. HF‐ACTION showed that patients who complied with an exercise training regime achieved a better outcome, although this may be confounded by the ability of patients with a good prognosis to exercise for longer.     

Clinical trials update from the European Society of Cardiology Heart Failure Meeting 2010: TRIDENT 1, BENEFICIAL,CUPID, RFA‐HF,MUSIC, DUEL,handheld BNP,phrenic nerve stimulation,CHAMPION and CABG with CRT study

This article provides information and a commentary on key trials relevant to the pathophysiology, prevention and treatment of heart failure (HF) presented at the annual meeting of the Heart Failure Association of the European Society of Cardiology held in Berlin. Unpublished reports should be considered as preliminary, since analyses may change in the final publication. Tonapofylline failed to show efficacy and was associated with an approximately 1% increased risk of seizures in patients with acute decompensated heart failure (ADHF) and renal dysfunction in TRIDENT. Results from BENEFICIAL do not support the use of alagebrium, an advanced glycation end‐product breaker, in clinically stable patients with relatively mild HF symptoms. CUPID showed encouraging preliminary results for augmentation of SERCA2a enzyme activity by gene transfection in patients with severe HF. The RFA‐HF study did not provide convincing evidence for the use of radiofrequency ablation for atrial fibrillation but was underpowered. A wearable, multi‐sensor patch showed potential for detecting impending HF decompensation in MUSIC. A comparison of low‐intensity oral diuretic therapy in patients hospitalized with ADHF suggested that torasemide was superior to furosemide in DUEL. The use of point‐of‐care B‐type natriuretic peptide and echocardiography failed to improve the rate of correct HF diagnosis in primary care. Phrenic nerve stimulation improved symptoms of sleep apnoea in a small study of patients with HF and central sleep apnoea. The use of a novel implantable pulmonary artery pressure monitoring system to guide patient management improved outcomes in the CHAMPION study. A study to evaluate a combined coronary artery bypass grafting (CABG) and epicardial cardiac resynchronization therapy implantation procedure reduced mortality compared with CABG alone.     

Clinical trials update from the American College of Cardiology 2007: ALPHA, EVEREST, FUSION II, VALIDD, PARR-2, REMODEL, SPICE, COURAGE, COACH, REMADHE, pro-BNP for the evaluation of dyspnoea and THIS-diet

This article provides information and a commentary on trials relevant to the pathophysiology, prevention and treatment of heart failure, presented at the American College of Cardiology meeting in March 2007. Unpublished reports should be considered as preliminary data, as analyses may change in the final publication. The ALPHA study suggested that patients with heart failure (HF) due to idiopathic dilated cardiomyopathy who have a negative T-wave alternans test have a good prognosis and are unlikely to benefit from ICD therapy. EVEREST provides some evidence of short-term symptom benefit of tolvaptan in patients with acute decompensated HF but no clinically important long-term benefit. FUSION II failed to show a benefit of nesiritide in patients with chronic decompensated HF. Reducing blood pressure in hypertensive patients improved diastolic dysfunction in VALIDD. Eplerenone did not improve left ventricular remodelling in mild to moderate chronic HF. Selecting HF patients for revascularisation using FDG-PET imaging did not significantly improve outcome. Crataegus extract added to standard HF therapy did not reduce morbidity or mortality in SPICE. The COURAGE study, conducted in patients without HF or major cardiac dysfunction, showed that PCI did not reduce cardiac morbidity or mortality and can be safely deferred in patients with stable coronary disease on optimal medical therapy. The COACH study failed to show that HF nurse-intervention could reduce hospitalisations but did show trends to lower mortality, especially amongst patients with reduced ejection fraction; however, the smaller REMADHE study suggested striking benefits on morbidity and mortality. A large study of BNP provided additional information on its ability to distinguish cardiac and pulmonary breathlessness. The importance of dietary intervention in post-MI patients was highlighted by the findings of THIS-diet study.     

Clinical trials update from the European Society of Cardiology Congress 2007: 3CPO, ALOFT, PROSPECT and statins for heart failure

This article provides information and a commentary on trials relevant to the pathophysiology, prevention and treatment of heart failure, presented at the European Society of Cardiology Congress 2007. Unpublished reports should be considered as preliminary data, as analyses may change in the final publication. In the 3CPO study, non-invasive ventilation produced a more rapid resolution of symptoms in patients hospitalised with acute cardiogenic pulmonary oedema; but had no effect on survival, compared to standard oxygen therapy. The ALOFT study showed that the selective oral renin inhibitor aliskiren reduces plasma BNP levels and is well tolerated in patients with heart failure receiving ACE inhibitors or ARBs, although the study was not powered to show clinical benefit. In the PROSPECT study, no echocardiographic measure of mechanical dyssynchrony was identified that was useful for identifying patients more or less likely to respond to CRT. Low dose atorvastatin reduced the incidence of sudden cardiac death in a small placebo controlled study of patients with advanced chronic heart failure.     

Clinical trials update from the American Heart Association meeting 2009: HEAAL,FAIR‐HF,J‐CHF,HeartMate II,PACE and a meta‐analysis of dose‐ranging studies of beta‐blockers in heart failure

This article provides information and a commentary on trials relevant to the pathophysiology, prevention, and treatment of heart failure presented at the annual meeting of the American Heart Association held in Orlando, Florida in 2009. Unpublished reports should be considered as preliminary, as analyses may change in the final publication. Patients with heart failure randomized to high‐dose losartan treatment (150 mg) in the HEAAL study had a reduced risk of death or heart failure hospitalization compared with patients in the low‐dose (50 mg) group. In FAIR‐HF, patients with heart failure and concomitant iron deficiency but without severe anaemia who received iron supplementation therapy demonstrated an improvement in symptoms at 24 weeks compared with placebo. The J‐CHF study was too small and was stopped too early to provide definitive evidence about the optimal dose of carvedilol for Japanese patients with heart failure. Results from the HeartMate II study suggest that continuous‐flow left ventricular assist devices may offer benefits over pulsatile‐flow devices for long‐term support in patients with advanced heart failure. In the PACE study, atrial synchronized right ventricular pacing induced adverse effects on left ventricular function compared with atrial synchronized biventricular pacing in patients with standard pacing indications and a normal ejection fraction.     

Clinical trials update from the European Society of Cardiology Meeting 2011: ARISTOTLE, SMART-AV: QLV substudy, SHIFT: echocardiography and quality of life substudies, European CRT Survey, and Basic Science Update

This article provides information and a commentary on key trials relevant to the pathophysiology, prevention, and treatment of heart failure presented at the European Society of Cardiology meeting held in Paris, France in August 2011. Unpublished reports should be considered as preliminary, since analyses may change in the final publication. Results from ARISTOTLE suggest that apixaban is more effective than warfarin for the prevention of stroke in patients with atrial fibrillation. Electrical dyssynchrony, measured by the time from onset of electrical activity on the surface ECG to activation of myocardium by intrinsic conduction at the pacing site (QLV), was a strong and independent predictor of improvement in ventricular function after cardiac resynchronization therapy (CRT) in an observational analysis of a subgroup of patients from the SMART-AV study. Subgroup analyses from SHIFT suggest that heart rate reduction with ivabradine causes favourable left ventricular remodelling and improves quality of life in patients with symptomatic systolic heart failure and an increased heart rate. The European CRT Survey reported outcome data.     

Clinical trials update from the Heart Failure Society of America Meeting 2009: FAST,IMPROVE‐HF,COACH galectin‐3 substudy,HF‐ACTION nuclear substudy,DAD‐HF,and MARVEL‐1

This article presents findings and a commentary on late‐breaking trials presented during the meeting of the Heart Failure Society of America in September 2009. Unpublished reports should be considered as preliminary, since analyses may change in the final publication. The FAST trial showed somewhat better performance of intrathoracic impedance for prediction of deterioration in patients with heart failure (HF) when compared with daily weighing. The IMPROVE‐HF study reported the benefits of education on the management of patients with systolic HF. Galectin‐3 appeared a useful method for improving risk stratification of patients with chronic HF in a substudy of the COACH trial. A nuclear substudy of the HF‐ACTION trial failed to demonstrate that resting myocardial perfusion imaging, a measure of myocardial scar and viability, was clinically useful. A small randomized controlled trial (DAD‐HF) suggested that the use of low‐dose dopamine in patients with acutely decompensated HF was associated with less deterioration in renal function and less hypokalaemia. The MARVEL‐1 trial raises further concerns about the safety of myoblast transplantation in ischaemic HF.     

Clinical trials update from the European Society of Cardiology–Heart Failure meeting 2015: AUGMENT‐HF,TITRATION, STOP‐HF,HARMONIZE, LION HEART,MOOD‐HF,and renin–angiotensin inhibitors in patients with heart and renal failure

This article provides an overview on the key trials relevant to the pathophysiology, prevention, and treatment of heart failure (HF) presented at the Heart Failure Association (HFA) of the European Society of Cardiology (ESC) annual meeting held in Seville, Spain in May 2015. Trials reported include AUGMENT‐AF (myocardial injections of calcium‐alginate hydrogel), a propensity score‐matched study of renin–angiotensin system antagonists in patients with HF and severe renal dysfunction, HARMONIZE (sodium zirconium cyclosilicate used to bind potassium), TITRATION, comparing two regimes for introducing LCZ696, STOP‐HF, a trial of intramyocardial stromal cell‐derived factor‐1, MOOD‐HF (escitalopram for patients with heart failure and depression), and LION HEART, a trial of intermittent levosimendan therapy. Unpublished reports should be considered as preliminary, since analyses may change in the final publication.
