Even in the era of percutaneous reperfusion therapy, left ventricular (LV) remodeling after myocardial infarction (MI) leading to heart failure remains a major health concern. Contractile dysfunction of the infarcted myocardium results in an increased pressure load, leading to maladaptive reshaping of the LV. Several percutaneous transcatheter procedures have been developed to deliver devices that restore LV shape and function. The purposes of this review are to discuss the spectrum of transcatheter devices that are available or in development for attenuation of adverse LV remodeling and to critically examine the available evidence for improvement of functional status and cardiovascular outcomes...

Measuring the level of B-type natriuretic peptide (BNP), as a guide to pharmacotherapy, can increase the survival of patients with heart failure. This study is aimed at systematically reviewing the studies conducted on the cost-effectiveness of BNP-guided care in patients with heart failure. Using the systematic review method, we reviewed the published studies on the cost-effectiveness of BNP-guided care in patients with heart failure during the years 2004 to 2017. The results showed that all studies clearly stated the time horizon of the study and included direct medical costs in their analysis...

Anti-apoptotic therapy for cardiomyocytes could be an effective strategy for preventing or treating heart failure. Notably, however, morphological evidence definitively demonstrating cardiomyocyte apoptosis has been very rare in actual heart diseases such as acute myocardial infarction and heart failure. By contrast, within the postinfarction heart, interstitial noncardiomyocytes such as granulation tissue cells do die via apoptosis to form scar tissue. Blockade of this apoptosis improves survival and mitigates ventricular remodeling and dysfunction during the chronic stage...

Acute heart failure (AHF) is a major burden disease, with a complex physiopathology, unsatisfactory diagnosis, treatment and a very poor prognosis. In the last two decades, a number of drugs have progressed from preclinical to early and late clinical development, but only a few of them have been approved and added to a stagnant pharmacological armamentarium. We have reviewed the data published on drugs developed for AHF since early 2000s, trying to recognise factors that have worked for a successful approval or for the stoppage of the program, in an attempt to delineate future trajectories for AHF drug development...

Transcatheter alcohol septal ablation (ASA) treatment of symptomatic patients with hypertrophic obstructive cardiomyopathy (HOCM) is based on the existence and degree of intraventricular obstruction. Patients with significant gradient and symptoms who do not respond to optimal medical therapy are eligible to gradient reduction through a surgical (septal myectomy) or a transcatheter (alcohol septal ablation) septal reduction. The latter encompasses occlusion of a septal branch perfusing the hypertrophied septum, which is involved in the generation of obstruction, by injecting ethanol into the supplying septal branch(es)...

Postmortem imaging is increasingly used in forensic practice as good complementary tool to conventional autopsy investigations. Over the last decade, postmortem cardiac magnetic resonance (PMCMR) imaging was introduced in forensic investigations of natural deaths related to cardiovascular diseases, which represent the most common causes of death in developed countries. Postmortem CMR application has yielded interesting results in ischemic myocardium injury investigations and in visualizing other pathological findings in the heart...

Type 2 diabetes mellitus (T2DM) is a major risk factor for several cardiovascular (CV) conditions, including heart failure (HF). However, until recently, no therapy to treat patients with diabetes could also reduce CV risks related to HF. The EMPA-REG OUTCOME trial with empagliflozin was the first to demonstrate significant cardioprotective benefits in this population. Its impressive 35% reduction in hospitalizations for HF drew the attention of the scientific community to the possibility that pharmacologic sodium-glucose cotransporter 2 (SGLT2) inhibition could be part of the armamentarium for treating patients with HF, with and without diabetes...

Elevated heart rate has been associated with worse prognosis both in the general population and in patients with heart failure. Heart rate is finely modulated by neurohormonal signals and it reflects the balance between the sympathetic and the parasympathetic limbs of the autonomic nervous system. For this reason, elevated heart rate in heart failure has been considered an epiphenomenon of the sympathetic hyperactivation during heart failure. However, experimental and clinical evidence suggests that high heart rate could have a direct pathogenetic role...

Glucagon-like peptide-1 (GLP-1) agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors produce some beneficial and deleterious effects in diabetic patients not mediated by their glycemic lowering effects, and there is a need for better understanding of the molecular basis of these effects. They possess antioxidant and anti-inflammatory effects with some direct vasodilatory action (animal and human trial data) that may indirectly influence heart failure (HF). Unlike GLP-1R agonists, signaling for HF adverse effects was observed with two DPP-4 inhibitors, saxagliptin and alogliptin...

Iron overload cardiomyopathy (IOC) is a major cause of death in patients with diseases associated with chronic anemia such as thalassemia or sickle cell disease after chronic blood transfusions. Associated with iron overload conditions, there is excess free iron that enters cardiomyocytes through both L- and T-type calcium channels thereby resulting in increased reactive oxygen species being generated via Haber-Weiss and Fenton reactions. It is thought that an increase in reactive oxygen species contributes to high morbidity and mortality rates...

Heart failure (HF) is often associated with different valve diseases, predominantly functional mitral and tricuspid regurgitation. However, the association between HF and aortic stenosis, particularly low-flow low-gradient aortic stenosis, is not infrequent. Severe mitral and tricuspid regurgitations, as well as aortic stenosis, in HF patients worsen prognosis and left ventricular dilatation and induce further reduction in left ventricular ejection fraction. Transcatheter edge-to-edge mitral and tricuspid valve repair and transcatheter aortic valve implantation could be an important therapeutic option with a satisfactory long-term outcome in HF patients with comorbidities and even in patients with severely depressed ejection fraction...

There have been increasing concerns about the unexpected effects of right ventricular (RV) pacing. We aimed to systematically evaluate the effect of biventricular (BiV) versus RV pacing on clinical events in patients with impaired AV conduction. We searched PubMed, EMBASE, and Cochrane Library for studies comparing BiV pacing with RV pacing in patients with AV block, through April 2017. We selected randomized controlled trials (RCTs) reporting data on mortality, hospitalization for heart failure (HF), and/or 6-min walk distance (6MWD)...

Exercise rehabilitation in heart failure patients has been shown to improve quality of life (QoL) and survival. It is also recommended in clinical practice guidelines for ventricular assist device (VAD) recipients. However, there have only been two meta-analyses on the effects of exercise rehabilitation in VAD patients, on only two outcomes. The objective of the review was to quantitatively evaluate the effect of exercise rehabilitation in VAD recipients on functional capacity, exercise physiology parameters, chronotropic responses, inflammatory biomarkers and neurohormones, heart structure and function, and clinical outcomes...

Heart failure with preserved ejection fraction (HFpEF) is an entity that still raises many questions. The agreement about definition, pathophysiology, and therapeutic approach is still missing. Arterial hypertension is present in majority of patients with HFpEF, and it is still not clear if it represent a risk factor or "sine qua non" condition for HFpEF development. The underlying mechanisms of hypertension and HFpEF involve the same biohumoral systems: renin-angiotensin-aldosterone, sympathetic nervous system, and oxidative stress...

Heart failure is a complex disease process, the manifestation of various cardiac and noncardiac abnormalities. General treatment approaches for heart failure have remained the same over the past decades despite the advent of novel therapies and monitoring modalities. In the same vein, the readmission rates for heart failure patients remain high and portend a poor prognosis for morbidity and mortality. In this context, development and implementation of improved algorithms for assessing and treating HF patients during hospitalization remains an unmet need...

Cardiac fibrosis is defined as excess deposition of extracellular matrix (ECM), resulting in tissue scarring and organ dysfunction. In recent years, despite the underlying mechanisms of cardiac fibrosis are still unknown, numerous studies suggest that epigenetic regulation of cardiac fibrosis. Cardiac fibrosis is regulated by a myriad of factors that converge on the transcription of genes encoding extracellular matrix protein, a process the epigenetic machinery plays a pivotal role. Epigenetic modifications contain three main processes: DNA methylation, histone modifications, and noncoding RNAs...

In patients with heart failure, increased sympathetic activity is associated with a positive chronotropic stimulation leading to accelerated resting heart rate. Elevated heart rate (HR) is a risk factor for cardiovascular events, both in the general population and in patients with heart failure. Ivabradine is a pure HR-lowering agent, and it does not affect myocardial contractility, blood pressure, intracardiac conduction, or ventricular repolarization. In clinical trials such as BEAUTIFUL, CARVIVA HF, SHIFT, and INTENSIFY in patients with systolic left ventricular dysfunction, heart rate reduction with ivabradine brought positive outcomes...

Heart failure (HF) and atrial fibrillation (AF) frequently coexist, and they can beget one another due to similar factors and shared pathophysiology. These pathophysiologic changes promote the episodes of AF, while they in turn predispose to the exacerbation of HF. In this review, we will discuss pathophysiological mechanisms shared by AF and HF. Patients with concomitant HF and AF are at a particularly high risk of thromboembolism, which contribute to even worse symptoms and poorer prognosis. Vitamin K antagonists (VKA) (warfarin) were the traditional medication in AF patients for the prevention of stroke, whereas the advance of novel non-VKA oral anticoagulants (NOACs) (dabigatran, apixaban, rivaroxaban, and edoxaban) is challenging these standard prescriptions...

While in adults major advances in heart failure therapy in patients with dilated cardiomyopathy were documented in the last two decades, research on the mechanism and therapies of heart failure in children with left ventricular dilated cardiomyopathy has lagged behind. Despite the lack of sufficient randomized prospective studies, ACE inhibitors are first line and ß-receptor antagonists are second-line strategies in children. Following the adult guidelines, without having data concerning the pediatric population, mineral corticoids are also accepted in the treatment of pediatric heart failure, while diuretics should only be used to achieve a euvolemic status...

Infectious myocarditis is the result of an immune response to a microbial infection of the heart. The blood vessels of the heart, both the intramyocardial microvasculature and the large epicardial coronary arteries, play an important role in the pathogenesis of infectious myocarditis. First of all, in addition to cardiomyocytes, endothelial cells of the cardiac (micro)vasculature are direct targets for infection. Moreover, through the expression of adhesion molecules and antigen presenting Major Histocompatibility Complex molecules, the blood vessels assist in shaping the cellular immune response in infectious myocarditis...
