Diabetic cardiomyopathy refers to a unique set of heart-specific pathological variables induced by hyperglycemia and insulin resistance. Given that cardiovascular disease (CVD) is the leading cause of death in the world, and type 2 diabetes incidence continues to rise, understanding the complex interplay between these two morbidities and developing novel therapeutic strategies is vital. Two hallmark characteristics specific to diabetic cardiomyopathy are diastolic dysfunction and cardiac structural mal-adaptations, arising from cardiac cellular responses to the complex toxicity induced by hyperglycemia with or without hyperinsulinemia...

OBJECTIVES: Prolonged activation of the β-1 adrenergic receptor (ADRB1) is associated with receptor desensitization. This process has been suggested to have important pathophysiological and clinical implications in conditions such as congestive heart failure. The contribution of genetic factors to this process is a patient of ongoing research. We have previously shown that the ADRB1 389 polymorphism affects the response to incremental dose infusion of the ADRB agonist dobutamine. The aim of the current study was to determine whether the ADRB1 389 polymorphism affects the hemodynamic response to constant dose infusion of dobutamine in healthy patients...

Evidence from large multicentre exercise intervention trials in heart failure patients, investigating both moderate continuous aerobic training and high intensity interval training, indicates that the 'crème de la crème' exercise programme for this population remains to be found. The 'aerobic/resistance/inspiratory (ARIS) muscle training hypothesis in heart failure' is introduced, suggesting that combined ARIS muscle training may result in maximal exercise pathophysiological and functional benefits in heart failure patients...

KEY POINTS: Diaphragmatic fatigue (DF) elicits a sympathetically mediated metaboreflex resulting in increased heart rate, blood pressure and limb vascular resistance. Women may be more resistant to DF compared to men and therefore, it was hypothesised that women would experience an attenuated inspiratory muscle metaboreflex during inspiratory pressure-threshold loading (PTL) performed to task failure. At the time of PTL task failure, the severity of DF was not different between sexes; however, inspiratory muscle endurance time was significantly longer in women than men...

OBJECTIVES: The authors sought to confirm a subgroup analysis of the prior FIX-HF-5 (Evaluate Safety and Efficacy of the OPTIMIZER System in Subjects With Moderate-to-Severe Heart Failure) study showing that cardiac contractility modulation (CCM) improved exercise tolerance (ET) and quality of life in patients with ejection fractions between 25% and 45%. BACKGROUND: CCM therapy for New York Heart Association (NYHA) functional class III and IV heart failure (HF) patients consists of nonexcitatory electrical signals delivered to the heart during the absolute refractory period...

BACKGROUND: Despite more than 200 years of clinical experience and a pivotal trial, recently published research has called into question the safety and efficacy of digoxin therapy in heart failure (HF). METHODS: HF-ACTION (ClinicalTrials.gov Number: NCT00047437) enrolled 2331 outpatients with HF and an EF ≤35% between April 2003 and February 2007 and randomized them to aerobic exercise training versus usual care. Patients were grouped according to prevalent digoxin status at baseline...

AIM: Myocardial Na+ /H+ exchanger-1 (NHE-1) hyperactivity and oxidative stress are interrelated phenomena playing pivotal roles in the development of pathological cardiac hypertrophy and heart failure. Exercise training is effective to convert pathological into physiological hypertrophy in the spontaneously hypertensive rats (SHR) and IGF-1 -key humoral mediator of exercise training- inhibits myocardial NHE-1, at least in normotensive rats. Therefore, we hypothesize that IGF-1 by hampering NHE-1 hyperactivity and oxidative stress should exert a cardioprotective effect in the SHR...

REVIEW

INTRODUCTION: Altitude is associated with a decrease in partial pressure of oxygen. Hypoxia induces pulmonary vasoconstriction with subsequent fixed increase in pulmonary artery pressure, and eventual right heart failure. CURRENT KNOWLEDGE: High altitude exposure is associated with an increase in pulmonary artery pressure that is proportional to initial vasoconstriction. Echocardiographic evaluations on a large number of subjects show that the altitude-induced increase in pulmonary pressure is generally modest and does not exceed the 25mmHg that are diagnostic of pulmonary hypertension...

OBJECTIVES: To investigate whether enrolment of patients in management programs after hospitalisation for heart failure (HF) reduces the likelihood of post-hospital adverse outcomes. DESIGN: Cohort study in which associations between adverse outcomes at 30 and 90 days for people hospitalised for HF and baseline clinical, socio-demographic and blood pathology factors, and with post-discharge management strategies, were assessed. Setting, participants: 906 patients with HF were prospectively enrolled in five Australian states at cardiology departments with expertise in treating people with HF...

Although often clinically unrecognized, the pulmonary circulation is frequently affected in patients with chronic obstructive pulmonary disease (COPD), and the presence of pulmonary vascular disease is associated with poor prognosis and frequent exacerbations. In most cases the presenting pulmonary hypertension (PH) is relatively mild, but in a subset of COPD patients, the presence of certain clinical features supports the existence of a "pulmonary vascular phenotype". Such a phenotype would be characterized by severe pre-capillary PH with strongly elevated pulmonary vascular resistance, moderate airflow limitation, severely decreased diffusion capacity for carbon monoxide, normo- or hypocapnia, circulatory exercise limitation and progressive right heart failure...

BACKGROUND: In patients with kidney failure requiring hemodialysis (HD) treatment, intradialytic exercise (IDEX) has been advocated for its feasibility and effectiveness in improving important health outcomes. However, IDEX as an adjunct therapeutic strategy is infrequently implemented, in part due to potential risks of IDEX, especially in patients with chronic volume overload. This study was performed to evaluate the safety of IDEX performed at different time points by examining its effect on intradialytic cardiovascular hemodynamics...

Introduction: Atrial septal defect (ASD) is the most common congenital cardiac anomaly diagnosed in adults. It often remains asymptomatic until the fourth or fifth decade of life. Significant left-to-right interatrial shunting is associated with the risk of heart failure, pulmonary hypertension and atrial fibrillation. Percutaneous ASD closure is a recognized method of treatment. Aim: To evaluate the clinical outcomes and physical capacity in patients undergoing transcatheter closure of ostium secundum ASD...

BACKGROUND/OBJECTIVE: Recent studies have indicated that cardiac autonomic dysfunction is an early sign of cardiovascular impairment in rheumatoid arthritis (RA). Previous studies have mainly focused on resting assessments; however, analysis of heart rate (HR) responses to exercise might provide additional information on cardiac autonomic dysfunction in this disease. Thus, we aimed to assess the HR responses during and after a maximal graded exercise test in patients with RA and healthy controls (CONs)...

BACKGROUND: Interleukin-1 (IL-1) blockade appears to improve anaerobic exercise in patients with systolic heart failure through improved left ventricular systolic performance. However, it is unclear whether IL-1 blockade affects left ventricular systolic performance. METHODS: We pooled data from two clinical trials of patients with systolic heart failure who were randomized to IL-1 blockade or placebo. We estimated changes in left ventricular systolic performance (left ventricular ejection fraction [LVEF] and end-systolic elastance [LVEes]) and pressure-volume area, a surrogate of oxygen consumption, after 14 days of treatment...

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...

Anthracycline is a standard drug for the treatment of breast cancer. However, anthracycline has great cardiotoxicity. Some patients stop chemotherapy during severe chemotherapy and even undergo serious heart failure. At the same time, there is lack of clinical study on whether aerobic exercise can reduce the cardiotoxicity of chemotherapy drugs. The purpose of this study is to investigate the effects of aerobic exercise on the cardiac function of patients with breast cancer after anthracycline therapy. The results showed that the control group LVEF decreased significantly...
