AIMS: Vitamin D deficiency is prevalent in heart failure (HF), but its relevance in early stages of heart failure with preserved ejection fraction (HFpEF) is unknown. We tested the association of 25-hydroxyvitamin D [25(OH)D] serum levels with mortality, hospitalizations, cardiovascular risk factors, and echocardiographic parameters in patients with asymptomatic diastolic dysfunction (DD) or newly diagnosed HFpEF. METHODS AND RESULTS: We measured 25(OH)D serum levels in outpatients with risk factors for DD or history of HF derived from the DIAST-CHF study...

BACKGROUND: Intracerebral haemorrhage (ICH) is a devastating condition, with more than half of patients dying or becoming dependent after such an event. Natriuretic peptides, frequently used in the management of heart failure, have been shown to correlate with disease severity and prognosis in brain disorders. The aim of this study was to test the hypothesis that NT-pro-BNP correlates with disease severity and is an independent prognostic marker for non-traumatic ICH patients. METHODS: A consecutive sample of 201 non-traumatic ICH patients, who were non-comatose on admission and medically treated in a stroke unit, were evaluated for in-hospital mortality and three-month functional dependency (modified Rankin Scale >2)...

Serum thrombospondin-2 (TSP-2) is a glycoprotein expressed in the extracellular matrix (ECM), which increases during tissue remodeling. It has been shown in recent studies that TSP-2 is a useful predictor of cardiovascular death in patients with heart failure (HF). However, the clinical importance of serum TSP-2 levels in a general population is still unknown. Therefore, we aimed to clarify the association between TSP-2 and clinical risk factors. A periodic epidemiological survey was performed in a community dwelling in the town of Uku, Nagasaki, Japan...

OBJECTIVES: Changes in the levels of serum creatinine and N-terminal of prohormone brain natriuretic peptide (NT-proBNP) are useful risk markers after cardiac resynchronization therapy (CRT). The diagnostic value of changes in serum uric acid levels has been established in chronic heart failure, but no data are available on the prognostic value of hyperuricemia in a CRT population. DESIGN: We measured markers of renal function [creatinine, blood urea nitrogen (BUN) and uric acid] and NT-proBNP levels of 129 heart failure patients undergoing CRT in a prospective, observational study...

The mechanistic target of rapamycin complex-1 (mTORC1) coordinates regulation of growth, metabolism, protein synthesis and autophagy1 . Its hyperactivation contributes to disease in numerous organs, including the heart1,2 , although broad inhibition of mTORC1 risks interference with its homeostatic roles. Tuberin (TSC2) is a GTPase-activating protein and prominent intrinsic regulator of mTORC1 that acts through modulation of RHEB (Ras homologue enriched in brain). TSC2 constitutively inhibits mTORC1; however, this activity is modified by phosphorylation from multiple signalling kinases that in turn inhibits (AMPK and GSK-3β) or stimulates (AKT, ERK and RSK-1) mTORC1 activity3-9 ...

BACKGROUND: The aetiology of perioperative myocardial injury is poorly understood and not clearly linked to pre-existing cardiovascular disease. We hypothesised that loss of cardioprotective vagal tone [defined by impaired heart rate recovery ≤12 beats min-1 (HRR ≤12) 1 min after cessation of preoperative cardiopulmonary exercise testing] was associated with perioperative myocardial injury. METHODS: We conducted a pre-defined, secondary analysis of a multi-centre prospective cohort study of preoperative cardiopulmonary exercise testing...

Estrogen has been demonstrated to protect the heart against cardiac remodelling and heart failure in women. G protein-coupled estrogen receptor 1 (GPER1) is a recently discovered estrogen receptor (ER) that is expressed in various tissues. However, the mechanisms by which estrogen protects the heart, especially the roles played by ERs, are not clear. In this study, we explored the effect of GPER1 activation on angiotensin II (Ang II)-induced cardiomyocyte hypertrophy and the involved signalling pathways and mechanisms...

Despite many recent advances in medicine, cardiogenic stroke is still a health problem with a high mortality rate. Cardiac biomarkers have been reported to be useful indicators for cardiogenic stroke and subsequent cerebrovascular events. However, there are no data directly comparing the cardiac biomarkers in stroke patients. We measured atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), N-terminal pro-brain natriuretic peptide (NT-proBNP), and high-sensitivity troponin T (hsTnT) levels and performed transthoracic and transesophageal echocardiography in 282 stroke patients...

Heart failure (HF) and chronic obstructive pulmonary disease (COPD) are important causes of morbidity and mortality worldwide. The association between the two conditions have significant systemic effects and a chronic, progressive evolution, affecting exercise tolerance and quality of life. The diseases share common risk factors, such as smoking, advanced age, and low-grade systemic inflammation. The majority of symptoms and physical signs, such as dyspnoea, orthopnea, nocturnal cough, exercise intolerance, muscle weakness may coexist in both pathologies...

Cardiac hypertrophy is widely diagnosed in clinical cardiac disorders. The pathophysiology of hypertrophy is complex and multifactorial, a series of molecular and cellular changes are participated, such as activation of different signaling pathways, a switch of fetal gene program in the myocardium, and apoptosis. Some biomarkers have been applied to assess cardiac hypertrophy including atrial natriuretic peptides (ANP), brain/B-type natriuretic peptides (BNP), and α- or β- Myosin Heavy Chain (MHC) in addition to others...

Pulmonary exposure to silver nanoparticles (AgNPs) revealed the potential of nanoparticles to cause pulmonary toxicity, cross the alveolar-capillary barrier, and distribute to remote organs. However, the mechanism underlying the effects of AgNPs on the cardiovascular system remains unclear. Hence, we investigated the cardiovascular mechanisms of pulmonary exposure to AgNPs (10 nm) with varying coatings [polyvinylpyrrolidone (PVP) and citrate (CT)], concentrations (0.05, 0.5 and 5 mg/kg body weight), and time points (1 and 7 days) in BALB/C mice...

Since mitochondria are energy-generating micro-organisms, most of the disorders in patients with mitochondrial diseases (mt-disease) are considered secondary to defects in ATP synthesis, although some other factors such as reactive oxygen species may be involved. A simultaneous oral administration of febuxostat and inosine was reported to elevate both hypoxanthine and ATP levels in peripheral blood. Based on those results, we attempted co-administration of febuxostat and inosine in two patients with mitochondrial disease: one patient with mitochondrial cardiomyopathy and the other patient with mitochondrial diabetes...
