A small number of cardiac stem cells that express the c-Kit and Nanog biomarkers can be differentiated into myocardial cells, which suggests that these stem cells may be able to repair damage and provide an internal reserve for tissue regeneration. It is unknown, however, whether the levels of myocardial stem cells are altered after heart failure (HF), and whether HF affects the myocardial regenerative ability. In this study, to address this question, we developed a rat model of chronic HF induced by Adriamycin, and examined the morphological changes in c-Kit and Nanog-expressing stem cells in heart tissue of normal and HF rats...

INTRODUCTION: Although it has been suggested that increased concentrations of activated platelet biomarkers are associated with increased risk of incident cardiovascular disease (CVD) in the general population, evidence for this association is still controversial. Thus, we tested the hypothesis that activated platelets, measured by higher concentrations of β-thromboglobulin, are associated with increased risk of incident CVD (coronary heart disease, heart failure ischemic stroke, and atrial fibrillation)...

BACKGROUND: Matrix metalloproteinase 9 (MMP9) has recently emerged as a risk predictor in patients with cardiovascular diseases. However, little is known about the significance of increased plasma MMP9 in patients with perioperative myocardial injury. We aimed to investigate the role of MMP9 in the occurrence of myocardial injury during off-pump coronary artery bypass grafting (OPCAB). METHODS: A total of 34 consecutive patients with coronary artery diseases (CAD) were recruited in this prospective, observational study...

Heart failure with preserved ejection fraction (HFpEF) is a common disease with high incidence and increasing prevalence. Patients suffer from functional limitation, poor health-related quality of life, and reduced prognosis. A pilot study in a smaller group of HFpEF patients showed that structured, supervised exercise training (ET) improves maximal exercise capacity, diastolic function, and physical quality of life. However, the long-term effects of ET on patient-related outcomes remain unclear in HFpEF. The primary objective of the Exercise training in Diastolic Heart Failure (Ex-DHF) trial is to investigate whether a 12 month supervised ET can improve a clinically meaningful composite outcome score in HFpEF patients...

AIMS: Whereas guidelines recommend the routine use of natriuretic peptides (NPs) in heart failure (HF) care, the clinical relevance and prognostic potential of midregional pro-adrenomedullin (MR-proADM) is less well established. We aimed to compare the prognostic potential of MR-proADM after acute decompensation for systolic HF with that of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and midregional pro-atrial NP (MR-proANP), to investigate the significance of high/rising MR-proADM, and to evaluate the incremental prognostic yield of repeat measurements...

Quantifying myocardial fibrosis (MF) with myocardial extracellular volume measures acquired during cardiovascular magnetic resonance promises to transform clinical care by advancing pathophysiologic understanding and fostering novel therapeutics. Extracellular volume quantifies MF by measuring the extracellular compartment depicted by the myocardial uptake of contrast relative to plasma. MF is a key domain of dysfunctional but viable myocardium among others (eg, microvascular dysfunction and cardiomyocyte/mitochondrial dysfunction)...

Cardiac dysfunction that develops during or after completion of cancer therapy is a growing health concern that should be addressed in a multidisciplinary setting. Cardio-oncology is a new discipline that focuses on screening, monitoring and treating cardiovascular disease during and after cancer treatment. A baseline cardiovascular risk assessment is essential. For high-risk patients, a tailored and detailed plan for cardiovascular management throughout treatment and beyond should also be established. Anthracycline and/or trastuzumab-containing chemotherapy and chest-directed radiation therapy are well known cardiotoxic cancer therapies...

BACKGROUND: How obesity or sex may affect the gene expression profiles of human cardiac hypertrophy is unknown. We hypothesized that body-mass index (BMI) and sex can affect gene expression profiles of cardiac hypertrophy. RESULTS: Human heart tissues were grouped according to sex (male, female), BMI (lean<25 kg/m(2), obese>30 kg/m(2)), or left ventricular hypertrophy (LVH) and non-LVH non-failed controls (NF). We identified 24 DE genes comparing female to male samples...

BACKGROUND: Despite left ventricular (LV) dysfunction contributing to mortality in chronic heart failure (HF), the molecular mechanisms of LV failure continues to remain poorly understood and myocardial biomarkers have yet to be identified. The aim of this pilot study was to investigate specific transcriptome changes occurring in cardiac tissues of patients with HF compared to healthy condition patients to improve diagnosis and possible treatment of affected subjects. METHODS: Unlike other studies, only dilated cardiomyopathy (DCM) (n = 2) and restrictive cardiomyopathy (RCM) (n = 2) patients who did not report family history of the disease were selected with the aim of obtaining a homogeneous population for the study...

Importance: Phosphodiesterase-5 inhibition with sildenafil compared with a placebo had no effect on the exercise capacity or clinical status of patients with heart failure with preserved ejection fraction (HFpEF) in the PhosphodiesteRasE-5 Inhibition to Improve Clinical Status and Exercise Capacity in Diastolic Heart Failure with Preserved Ejection Fraction (RELAX) clinical trial. Metabolic impairments may explain the neutral results. Objective: To test the hypothesis that profiling metabolites in the RELAX trial would clarify the mechanisms of sildenafil effects and identify metabolites associated with clinical outcomes in HFpEF...

INTRODUCTION: Despite the widespread use of the mouse transverse aortic constriction heart failure model, there are no reports on the characterization of the standard-of-care agent carvedilol in this model. METHODS: Left ventricular pressure overload was produced in mice by transverse aortic constriction between the innominate and left common carotid arteries. Carvedilol was administered at multiple dose levels (3, 10 and 30 mg/kg/day per os; yielding end-study mean plasma concentrations of 0...

Cardiovascular disease (CVD) is the leading cause of death and disability worldwide. The primary prevention of CVD is dependent upon the ability to identify high-risk individuals long before the development of overt events. This highlights the need for accurate risk stratification. An increasing number of novel biomarkers have been identified to predict cardiovascular events. Biomarkers play a critical role in the definition, prognostication, and decision-making regarding the management of cardiovascular events...

Combined pulmonary insufficiency (PI) and stenosis (PS) is a common long-term sequela after repair of many forms of congenital heart disease, causing progressive right ventricular (RV) dilation and failure. Little is known of the mechanisms underlying this combination of preload and afterload stressors. We developed a murine model of PI and PS (PI+PS) to identify clinically relevant pathways and biomarkers of disease progression. Diastolic dysfunction was induced (restrictive RV filling, elevated RV end-diastolic pressures) at 1 month after generation of PI+PS and progressed to systolic dysfunction (decreased RV shortening) by 3 months...

OBJECTIVES: Preeclampsia (PE) is strongly associated with heart failure (HF) later in life. During preeclamptic pregnancy the left ventricle (LV) remodels in a concentric way. This aberrant remodelling often persists after delivery. The concentric remodelling during PE can induce molecular signatures that may explain the associated increased risk of HF. This signature may be evaluated in terms of microRNAs (miRNAs). This review evaluates existing literature on miRNA expression data in concentric remodelling on the one hand and PE on the other to generate a list of overlapping miRNA expression patterns in both...

Disturbances of collagen metabolism may alter the myocardial collagen network and contribute to cardiac remodeling and prognosis in heart failure (HF). Collagen type I synthesis and degradation can be assessed indirectly by the circulating biomarkers carboxy-terminal propeptide (PICP) and carboxy-terminal telopeptide (CITP), respectively. We examined the associations between PICP and CITP and long-term mortality in patients with HF. The Optimizing Congestive Heart Failure Outpatient Clinic (OPTIMAL) project studied patients aged ≥60 years with New York Heart Association class II to IV and HF with reduced ejection fraction (EF) hospitalized with acute HF during 1996 to 1999...

Background.: Uraemic cardiomyopathy, a process mainly associated with increased myocardial fibrosis, is the leading cause of death in chronic kidney disease patients and can be prevented by vitamin D receptor activators (VDRAs). Since some microRNAs (miRNAs) have emerged as regulators of the fibrotic process, we aimed to analyse the role of specific miRNAs in VDRA prevention of myocardial fibrosis as well as their potential use as biomarkers. Methods.: Wistar rats were nephrectomized and treated intraperitoneally with equivalent doses of two VDRAs: calcitriol and paricalcitol...

BACKGROUND: B-type natriuretic peptide (BNP) and the N-terminal fragment of pro-BNP (NT-pro-BNP) are established biomarkers of heart failure. Increased levels of natriuretic peptide (NP) have been associated with poor outcomes in acute exacerbation of COPD (AECOPD); however, most studies did not address the conditions that can also increase NT-pro-BNP levels. We aimed to determine if NT-pro-BNP levels correlate with outcomes of AECOPD in patients without heart failure and other conditions that can affect NT-pro-BNP levels...
