AIMS: Although inflammation plays an important role in the pathogenesis of heart failure (HF), the precise pathophysiological role of inflammation in HF with preserved left ventricular ejection fraction (HFpEF) still remains unclear. Hence, we examined the clinical significance of plasma neopterin, an inflammatory biomarker, in HFpEF patients. METHODS AND RESULTS: In the present study, we recruited consecutive HFpEF patients hospitalized in Kumamoto University Hospital, and further measured plasma neopterin by high-performance liquid chromatography and serum derivatives of reactive oxidative metabolites (DROM), a new biomarker of reactive oxygen species...

Catestatin (CST) is a proteolytic fragment of Chromogranin A with a broad spectrum of activities in the cardiovascular system. The level of plasma CST increases in chronic heart failure patients, but its potential relationship to patient prognosis is unknown. In this study, we measured plasma CST levels in 202 chronic heart failure patients and followed them for a median of 52.5 months. The plasma CST level was higher in patients with all-cause death and cardiac death than in survivors. According to univariate COX regression, higher plasma CST levels predicted increased risk of all-cause and cardiac death...

BACKGROUND: Although several new drugs have been approved in recent years, pulmonary arterial hypertension (PAH) remains a rapidly progressive disease with a poor prognosis. Ambrisentan, a selective endothelin type A antagonist, has been approved for treatment of PAH. This open label study assessed the efficacy and safety of ambrisentan in Chinese subjects with PAH. METHODS: Eligible patients with PAH (World Health Organisation [WHO] functional class [FC] II orIII) were enrolled and received Ambrisentan (5 mg) once daily for a 12-week preliminary evaluation period, and a 12-week dose-adjustment period (dose titration to 10 mgallowed)...

Functional mitral regurgitation (MR) is common in patients with heart failure and left ventricular (LV) dysfunction. MitraClip (MC) is a novel therapeutic option for patients with high-risk MR. Similar to LV dysfunction, right ventricular dysfunction (RVD) is an important predictor of patients with heart failure. We aimed to clarify the effect of RVD on outcomes of functional MR and LV dysfunction after MC implantation. We examined 117 patients with severe functional MR and reduced LV ejection fraction (≤40%) treated with MC...

BACKGROUND: Diverse cardiovascular signaling routes have been considered critical for Chagas cardiomyopathy caused by the protozoan parasite Trypanosoma cruzi. Along this line, T. cruzi infection and endothelin-1 (ET-1) have been shown to cooperatively activate the Ca(2+)/NFAT cascade in cardiomyocytes, leading to cyclooxygenase type 2 (COX-2) induction and increased release of prostanoids and prohypertrophic peptides. PURPOSE: To determine whether the well-known cardioprotective and anti-inflammatory effects of curcumin (Cur) could be helpful to interfere with this key machinery for pathogenesis of Chagas myocarditis...

Bronchopulmonary dysplasia (BPD) is often complicated by pulmonary hypertension (PH). We investigated three biomarkers potentially suitable as screening markers for extremely preterm infants at risk of BPD-associated PH. In this prospective observational cohort study conducted in a tertiary neonatal intensive care unit, 83 preterm infants with BPD born <28 weeks gestation and still inpatients at 36 weeks corrected age received an echocardiogram and blood tests of B-type natriuretic peptide (BNP), troponin I, and YKL-40...

BACKGROUND: Diabetes has been linked epidemiologically to increased cancer incidence and mortality. Growth differentiation factor 15 (GDF-15) is increased in patients with diabetes and has recently been linked to the occurrence of cancer. We investigated whether circulating GDF-15 concentrations can predict the incidence of malignant diseases in a diabetic patient cohort already facing increased risk for cancer. METHODS: We prospectively enrolled a total of 919 patients with type 2 diabetes and no history of malignant disease, who were clinically followed up for 60 months...

Brain natriuretic peptide (BNP), also known as a B-type natriuretic peptide, is one of the important biomarkers with a proven role in the diagnosis of congestive heart failure (CHF). Researchers from the different clinical field have researched into the performance features of BNP testing in the acute care set-up to assist and improve in diagnosing CHF and in predicting future morbidity and mortality rates. The potency of BNP has also been researched into in cases like myocardial ischemia and infarction, cor pulmonale, and acute pulmonary embolism (PE)...

OBJECTIVE: Primary aldosteronism (PA) represents the most common cause of secondary hypertension. A higher risk of cardiovascular events has been reported in patients with PA than in otherwise similar patients with essential hypertension (EH). So far, only a few studies investigated the levels of plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in PA patients compared to EH patients. DESIGN AND METHOD: We studied 385 consecutive patients with PA and 385 with EH individually matched for age, gender, body mass index (BMI), blood pressure values and duration of hypertension...

The burden of cardiovascular diseases (CVD) in general and heart failure (HF) in particular continues to increase worldwide. CVD are major contributors to death and morbidity and recognized as important drivers of healthcare expenditure. Chronic overactivity of the renin-angiotensin-aldosterone system (RAAS) plays a key role in human hypertension and HF pathophysiology. RAAS is fundamental in the overall regulation of cardiovascular homeostasis through the actions of hormones, which regulate vascular tone, and specifically blood pressure through vasoconstriction and renal sodium and water retention...

Atrial natriuretic peptide (ANP) and B-type natriuretic peptide (BNP) are the cardiac natriuretic peptides (NP), true "cardiometabolic" hormones well known for their renal, endocrine and cardiovascular activities leading to reduced sodium reabsorption and arterial blood pressure. These effects are mainly mediated by the second messenger cGMP that also stimulates lipolysis, mitochondriogenesis and a thermogenic program with potency similar to catecholamines. Two distinct NP receptors modulate the final response to cardiac NP: the cGMP-signaling receptor NPRA and the clearance receptor NPRC...

OBJECTIVE: Loss of the nocturnal blood pressure (BP) drop is a risk factor for cardiovascular outcomes. However, clinical parameters that predispose to changes in nocturnal BP are currently uncertain. Given the possible involvement of salt sensitivity in nocturnal BP levels, we investigated a hypothesized association between plasma B-type natriuretic peptide (BNP) levels - a marker of body fluid retention - and nocturnal BP in a general population. METHODS: Study participants were 1020 general individuals...

OBJECTIVE: Psychological constructs are associated with cardiovascular health, but the biological mechanisms mediating these relationships are unknown. We examined relationships between psychological constructs and markers of inflammation, endothelial function, and myocardial strain in a cohort of post-acute coronary syndrome (ACS) patients. METHODS: Participants (N = 164) attended study visits 2 weeks and 6 months after ACS. During these visits, they completed self-report measures of depressive symptoms, anxiety, optimism, and gratitude; and blood samples were collected for measurement of biomarkers reflecting inflammation, endothelial function, and myocardial strain...

TOPCAT was a multinational clinical trial of 3,445 heart failure with preserved ejection fraction (HFpEF) patients that enrolled in 233 sites in six countries in North America, Eastern Europe and South America. Patients with a heart failure hospitalization in the last 12 months or an elevated B-type natriuretic peptide (BNP) were randomized to the mineralocorticoid receptor antagonist spironolactone vs. placebo. Sites in Russia and the Republic of Georgia provided the majority of early enrollment, primarily based on the hospitalization criterion since BNP levels were initially unavailable there...
