    ABSTRACT: Recent efforts have reduced the mortality from coronary artery disease (CAD), with the consequent increase in heart failure with reduced left ventricular function, referred to as ischaemic cardiomyopathy (ICM). As ischemic left ventricular (LV) dysfunction may be partially or completely reversible by revascularization in the presence of viable myocardium, the assessment of myocardial viability is central to the management of ICM. Decades of observational analyses have provided positive evidence for the role of revascularization in hibernating myocardium in improving survival. However, recently the Surgical Treatment for Ischaemic Heart Failure (STICH) trial has challenged this notion, highlighting the noninferiority of optimal medical therapy (OMT) over revascularization and OMT. In this review, we discuss noninvasive imaging modalities to assess myocardial viability and the impact of myocardial viability on revascularization. We critically appraise the STICH trial and suggest an algorithm for viability testing before revascularization in patients with ICM and significant LV dysfunction.

    ABSTRACT: Most cardiovascular implantable electronic devices (CIEDs) require a ventricular lead to be placed across the tricuspid valve. Tricuspid regurgitation (TR) is an understudied clinical complication of right ventricular lead implantation and its clinical significance is unknown. We review the incidence, predictors, and current management of TR as a complication of ventricular lead implantation. Emerging technologies, including leadless pacing devices and subcutaneous systems, offer the benefit of little or none tricuspid valve disruption.

    ABSTRACT: Heart failure (HF) is a major healthcare concern. Acute HF carries a high mortality and a high rehospitalisation rate. HF has a variety of detrimental effects on other organs. In recent years, the interactions between heart failure and the kidney have been the subject of significant investigations; this interaction, defined as “cardiorenal syndrome”, is relatively well characterized. We describe here another interaction between the heart and the liver, the “cardiohepatic syndrome”, in acute HF patients. Recent publications have shown that liver function test (LFT) abnormalities were associated with AHF severity. Clinical signs of systemic congestion were found to be associated with cholestasis, when signs of hypoperfusion were associated with liver cytolysis. Defining the LFT profile in AHF may play an important role in the future management of AHF patients.

    ABSTRACT: Growth differentiation factor 15 (GDF-15) is a stress-responsive cytokine expressed in the cardiovascular system. GDF-15 is emerging as a biomarker of cardiometabolic risk and disease burden. GDF-15 integrates information from cardiac and extracardiac disease pathways that are linked to the incidence, progression, and prognosis of heart failure (HF). Increased circulating levels of GDF-15 are associated with an increased risk of developing HF in apparently healthy individuals from the community. After an acute coronary syndrome, elevated levels of GDF-15 are indicative of an increased risk of developing adverse left ventricular remodeling and HF. In patients with established HF, the levels of GDF-15 and increases in GDF-15 over time are associated with adverse outcomes. The information provided by GDF-15 is independent of established risk factors and cardiac biomarkers, including BNP. More studies are needed to elucidate how the information provided by GDF-15 can be used for patient monitoring and formulating treatment decisions. Further understanding of the pathobiology of GDF-15 may lead to the discovery of new treatment targets in HF.

    ABSTRACT: Anemia is a common comorbidity in heart failure (HF), and is associated with increased morbidity and mortality. However, it remains unclear whether anemia is merely a marker of poor prognosis or whether anemia itself confers risk. The pathogenesis of anemia in HF is multifactorial. Iron deficiency also confers risk in HF, either with or without associated anemia, and treatment of iron deficiency improves the functional status of patients with HF. An ongoing large clinical trial studying the use of darbepoetin–alfa in patients with anemia and systolic HF is expected to provide information that should improve our understanding of anemia in HF.

    ABSTRACT: Limited donor availability for orthotopic cardiac transplantation has led surgeons to develop surgical alternatives to treat congestive heart failure as a result of ischemic cardiomyopathy. Coronary revascularization plays a clear role in patients with ischemic cardiomyopathy, substantial viable myocardium subtended by coronary stenoses, and presence of anginal symptoms. It is unclear whether patients with heart failure symptoms but no angina benefit from bypass surgery. Some of these patients present with left ventricular dilatation and akinetic/dyskinetic scars, and are therefore candidates for surgical ventricular restoration. Current evidence is lacking as to whether ventricular reconstruction should be performed along with coronary revascularization. Functional mitral regurgitation is often seen in patients with end-stage cardiomyopathy, and its presence portends decreased survival. Mitral valve repair has been shown to improve quality of life, functional class, and to contribute to left ventricle reverse remodeling; however, it has been insufficient in improving survival.

    ABSTRACT: Echocardiography is the most important imaging tool for managing heart failure patients. With the advent of cardiac resynchronization therapy (CRT), its role has been broadened by data pertaining to patient selection, optimization of device settings, and outcome assessment. Beyond ejection fraction determination, echocardiographic methods that measure tissue velocity and strain may have the capability to determine degree of mechanical dyssynchrony and possibly predict likelihood of benefit with CRT. After implantation (as the ventricles are fully paced, adjusting the atrioventricular delay [atrioventricular optimization]), the timing of the right ventricular and left ventricular lead stimulation (ventricular-ventricular optimization) to achieve maximal cardiac filling or ejection may be clinically important. Atrioventricular and ventricular-ventricular optimization rely on echocardiography to determine optimal values. In long-term follow-up, serial measurement of left ventricular volume has significant correlation with mortality and is a reasonable measure of successful CRT; echocardiography is uniquely suited for this purpose.

    ABSTRACT: More than half of patients with heart failure (HF) have a normal ejection fraction (EF). These patients are typically elderly, are predominantly female, and have a high incidence of multiple comorbid conditions associated with development of ventricular hypertrophy and/or interstitial fibrosis. Thus, the cause of HF has been attributed to diastolic dysfunction. However, the same comorbidities may also impact myocardial systolic, ventricular, vascular, renal, and extracardiovascular properties in ways that can also contribute to symptoms of HF by way of mechanisms not related to diastolic dysfunction. Accordingly, the descriptive term HF with normal EF has been suggested as an alternative to the mechanistic term diastolic HF. In this article, we review the current understanding of nondiastolic mechanisms that may contribute to the HF with normal EF syndrome to highlight potential pathways for research that may lead to new targets for therapy.

    ABSTRACT: Cardiogenic shock complicates up to 7% of ST-segment elevation myocardial infarctions and 2.5% of non-ST-segment elevation myocardial infarctions, with an associated mortality of 50% to 70%. Primary cardiac pump failure is followed by secondary vital organ hypoperfusion and subsequent activation of various cascade pathways, resulting in a downward spiral leading to multiple organ failure and, ultimately, death. Immediate restoration of cardiac output by means of percutaneous ventricular assist devices restores hemodynamic stability and is an important advance in the management of patients with severe left ventricular dysfunction and cardiogenic shock. This article reviews available evidence supporting the use of percutaneous ventricular assist devices in patients suffering from cardiogenic shock.

    ABSTRACT: Atrial fibrillation (AF) and congestive heart failure (CHF) are common cardiac conditions that frequently coexist. There is a complex interplay between the two conditions, with each increasing the morbidity and mortality associated with the other. The management of AF in patients with CHF requires special care because of the increased risk of antiarrhythmic drug therapy in the group. This report reviews current treatment options and assesses the role of the newer therapies of biventricular pacing for CHF and radiofrequency ablation for AF. It also discusses results of the AF-CHF study, which were reported in November 2007.

    ABSTRACT: Cardiac resynchronization therapy (CRT) improves clinical outcome and survival in advanced heart failure. However, some patients do not respond clinically or show improvement in left ventricular function. Our focus has turned to why such “nonresponders” exist. Follow-up of CRT has led to several explanations, varying by individual patient, and has shown the importance of device programming in CRT in heart failure. The failing heart displays delayed contraction in the ventricle, also referred to as mechanical dyssynchrony. Simply pacing both ventricles simultaneously might not be adequate to optimize systolic function. Individually tailoring the atrioventricular (AV) timing can improve left ventricular filling and cardiac output, and adjusting the interventricular (VV) pacing delay has also been shown to improve hemodynamics. Increasing evidence regarding AV and VV optimization is emerging. This article reviews the current data on optimization, including the physiology, numerous approaches, and current issues.

    ABSTRACT: As part of the recommended modern post-myocardial infarction (MI) management, including reperfusion strategies, antiplatelet therapy, and beta-blockers, we may wonder whether the impact of early inhibition of the renin-angiotensin system (RAS) is as important as it was 20 years ago. This review demonstrates that significant clinical benefit can be derived from angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) even when added to other currently recommended treatment strategies in post-MI patients. Moreover, the effects of RAS inhibition extend far beyond the early post-MI neurohormonal activation and left ventricular remodeling phases. The favorable effects of RAS inhibition on important prognostic markers such as atrial fibrillation, renal function, and diabetes have recently been unraveled. Post-MI RAS inhibition also benefits all age groups, including elderly patients.

    ABSTRACT: Heart transplantation remains the gold standard treatment for "end-stage" dilated cardiomyopathy. However, its epidemiologic impact on the heart failure problem continues to be small due to limited donor organ availability and contraindications. Therefore, several "conventional" surgical procedures have been developed to reverse the vicious cycle of ventricular remodeling that accompanies systolic heart failure and to improve symptoms and survival of the patients. This review discusses indications, results, and limitations of the most common surgical methods currently used to arrest or reverse cardiac remodeling.

    ABSTRACT: Studies suggest that cardiac transfer of stem and progenitor cells can have a favorable impact on tissue perfusion and contractile performance after acute myocardial infarction (AMI). Although the mechanistic background of stem cell therapy is still intensely debated, stem cell therapy has been introduced into the clinical setting, where the first randomized, controlled trials indicate that it is feasible and safe in patients. Preliminary efficacy data indicate that stem cells have the potential to enhance myocardial perfusion and/or contractile performance in patients with AMI. The field now is rapidly moving toward intermediate-size, double-blind trials to gather more safety and efficacy data and the first insights into clinical end points. Ultimately, large outcome trials will be needed. At the same time, continued basic research is needed to elucidate the underlying mechanism of stem cell therapy.
