Almost 30 years ago, the protein, atrial natriuretic peptide, was identified as a heart-secreted hormone that provides a peripheral signal from the myocardium that communicates to the rest of the organism to modify blood pressure and volume under conditions of heart failure. Since then, additional peripheral factors secreted by the heart, termed cardiokines, have been identified and shown to coordinate this interorgan cross talk. In addition to this interorgan communication, cardiokines also act in an autocrine/paracrine manner to play a role in intercellular communication within the myocardium...

BACKGROUND: Subclinical left ventricular (LV) dysfunction has been inconsistently associated with early cognitive impairment, and mechanistic pathways have been poorly considered. We investigated the cross-sectional relationship between LV dysfunction and structural/functional measures of the brain and explored the role of potential mechanisms. METHOD AND RESULTS: A total of 1338 individuals (69±6 years) from the Southall and Brent Revisited study underwent echocardiography for systolic (tissue Doppler imaging peak systolic wave) and diastolic (left atrial diameter) assessment...

BACKGROUND: Cardiac hypertrophy is highly prevalent in patients with type 2 diabetes mellitus (T2DM). Experimental evidence has implied that pregnant women with T2DM and their children are at an increased risk of cardiovascular diseases. Our previous mouse model study has revealed that maternal T2DM induces structural heart defects in their offspring. OBJECTIVE: The present study aims to determine whether maternal T2DM induces embryonic heart hypertrophy in a murine model of diabetic embryopathy...

BACKGROUND: Cerebral endothelial dysfunction occurs in a spectrum of neurodegenerative diseases. Whether biomarkers of microvascular endothelial dysfunction can predict dementia is largely unknown. We explored the longitudinal association of midregional pro-atrial natriuretic peptide (MR-proANP), C-terminal endothelin-1 (CT-proET-1) and midregional pro-adrenomedullin (MR-proADM) with dementia and subtypes among community-dwelling older adults. METHODS: A population-based cohort of 5,347 individuals (men, 70%; age, 69±6 years) without prevalent dementia provided plasma for determination of MR-proANP, CT-proET-1 and MR-proADM...

Objectives: To define the role of single or serial measurement of endothelin 1 (ET-1) for prognostication beyond traditional and modern markers of risk in heart failure (HF). Methods: In total, 115 patients with chronic systolic HF were followed for 10 months. Clinical assessment and ET-1, N-terminal pro-B-type natriuretic peptide (NT-proBNP), highly sensitive troponin I (hsTnI), soluble ST2 (sST2), and galectin 3 were measured at each visit. Results: Elevated ET-1 was associated with worse HF, lower right ventricular function, higher pulmonary pressure, and higher left atrial volume index despite similar left ventricular function...

OBJECTIVE: To assess the incidence, possible risk factors and prognosis of pulmonary arterial hypertension (PAH) in critically ill elderly patients. METHODS: We selected 122 cases admitted to the ICU, ages 60-93 years old. An echocardiography examination was performed within four days after admission to the ICU. PAH is usually suspected if the patient's pulmonary artery systolic pressure ≥ 40 mmHg. We collected echocardiography data, relevant clinical data and routine laboratory data; we then used a statistical method to analyze the risk factors for PAH in critically ill elderly patients and examined its impact on the prognosis...

Background -Current strategies for cardiovascular disease (CVD) risk assessment among adults without known CVD are limited by suboptimal performance and a narrow focus on only atherosclerotic CVD (ASCVD). We hypothesized that a strategy combining promising biomarkers across multiple different testing modalities would improve global and atherosclerotic CVD risk assessment among individuals without known CVD. Methods -We included participants from the Multi-Ethnic Study of Atherosclerosis (MESA, n=6621) and Dallas Heart Study (DHS, n=2202) who were free from CVD and underwent measurement of left ventricular hypertrophy by electrocardiogram (ECG-LVH), coronary artery calcium (CAC), N-terminal pro B-type natriuretic peptide (NT-proBNP), high-sensitivity cardiac troponin T (hs-cTnT) and high-sensitivity C-reactive protein (hs-CRP)...

Fasting reduces glucose levels and protects mice against chemotoxicity, yet drugs that promote hyperglycemia are widely used in cancer treatment. Here, we show that dexamethasone (Dexa) and rapamycin (Rapa), commonly administered to cancer patients, elevate glucose and sensitize cardiomyocytes and mice to the cancer drug doxorubicin (DXR). Such toxicity can be reversed by reducing circulating glucose levels by fasting or insulin. Furthermore, glucose injections alone reversed the fasting-dependent protection against DXR in mice, indicating that elevated glucose mediates, at least in part, the sensitizing effects of rapamycin and dexamethasone...

BACKGROUND: Atrial natriuretic peptide (ANP) and its prohormone activating enzyme are associated with central obesity, suggesting there may be a potential relationship between proANP1-98 and central obesity. However, the association is still lack of population-based evidence. We explored the association in a general population of China. METHODS: We measured plasma proANP1-98, waist circumference and other traditional biomarkers in 2203 participants aged≥30y. Multivariate logistic regression models were used to determine the association between plasma proANP1-98 and central obesity, and odds ratio (OR) and 95% confidence interval (CI) were calculated...

BACKGROUND: Metabolic profiles have been shown to provide prognostic information in patients with heart failure (HF). Galectin-3 (Gal-3), indicating cardiac fibrosis, is a documented biomarker of prognosis in HF. It is unknown whether metabolic profiles provide prognostic value better than Gal-3. METHODS AND RESULTS: This study analyzed 212 hospitalized HF patients, measuring metabolic score (composed by butyrylcarnitine, dimethylarginine/arginine ratio, spermidine, and total essential amino acids) and Gal-3...

Hyponatremia, serum sodium < 135 mEq/L, is the most common electrolyte abnormality and is in a state of flux. Hyponatremic patients are symptomatic and should be treated but our inability to consistently determine the causes of hyponatremia has hampered the delivery of appropriate therapy. This is especially applicable to differentiating syndrome of inappropriate antidiuresis (SIAD) from cerebral salt wasting (CSW) or more appropriately, renal salt wasting (RSW), because of divergent therapeutic goals, to water-restrict in SIAD and administer salt and water in RSW...

Cardiac hypertrophy is an early hallmark during the clinical course of heart failure and regulated by various signalling pathways. Recently, we observed that mouse embryonic fibroblasts from CD38 knockout mice were significantly resistant to oxidative stress such as H2 O2 -induced injury and hypoxia/reoxygenation-induced injury. In addition, we also found that CD38 knockout mice protected heart from ischaemia reperfusion injury through activating SIRT1/FOXOs-mediated antioxidative stress pathway. However, the role of CD38 in cardiac hypertrophy is not explored...

PURPOSE: sST2 (soluble suppression of tumorigenicity 2), a member of the interleukin-1 family, has been suggested to play a role in cardiac remodeling and inflammatory signaling. We assessed the association between sST2 in patients with stable coronary heart disease (CHD) with multiple cardiovascular outcomes and total mortality, simultaneously controlling for a large number of potential confounders. METHODS: Plasma concentrations of sST2 (ELISA, Critical Diagnostics) were measured at baseline in a cohort of 1081 patients...

Diabetic cardiomyopathy (DCM) is highly prevalent in type 2 diabetes (T2DM) patients. Zinc is an important essential trace metal, whose deficiency is associated with various chronic ailments, including vascular diseases. We assessed T2DM B6.BKS(D)-Leprdb/J (db/db) mice fed for six months on a normal diet containing three zinc levels (deficient, adequate, and supplemented), to explore the role of zinc in DCM development and progression. Cardiac function, reflected by ejection fraction, was significantly decreased, along with increased left ventricle mass and heart weight to tibial length ratio, in db/db mice...
