BACKGROUND: Diabetes is a common disease in heart failure and its prevalence ranges from 10 to 30%. ST-2 is a novel biomarker of myocardial fibrosis and remodelling in heart failure and may be involved in the inflammatory process of diabetes mellitus. In this study, we sought: to evaluate levels of ST-2 and B-type natriuretic peptide (BNP) in groups with acute heart failure with and without diabetes; to analyse the prognostic impact of ST-2 over a 6-month follow-up period. METHODS: We performed an echocardiographic examination and measured ST-2 and BNP within 24 h of hospital admission...

BACKGROUND: Right heart failure (RHF) after left ventricular assist device (LVAD) implantation is associated with high morbidity and mortality. Existing risk scores include semiquantitative evaluation of right ventricular (RV) dysfunction. This study aimed to determine whether quantitative evaluation of both RV size and function improve risk stratification for RHF after LVAD implantation beyond validated scores. METHODS AND RESULTS: From 2009 to 2015, 158 patients who underwent implantation of continuous-flow devices who had complete echocardiographic and hemodynamic data were included...

INTRODUCTION/OBJECTIVES: Patients with rheumatoid arthritis (RA) are at increased risk for congestive heart failure (CHF) and left ventricular diastolic dysfunction (LVDD), as compared to the general population. High disease activity is to be associated with higher incidence of cardiovascular disease (CVD), CHF, and mortality in RA patients. LVDD is not anticipated in RA patients without CVD symptoms and may be underdiagnosed especially in those with low disease activity. METHOD: The study group consisted of 70 RA patients (54 women, 16 men) with no CVD and 33 healthy controls, of comparable age...

Background: Transplant renal vein thrombosis (TRVT) is a severe vascular complication and is caused by various factors, including recipient factors, donor factors, immunosuppression regimens, and surgical techniques. Despite adequate interventions, including thrombolytic therapy or surgical thrombectomy, successful salvage of the allograft is often difficult. We observed a case of TRVT induced by compression of the renal vein immediately after intraoperative abdominal closure. Case presentation: A 41-year-old male underwent ABO-compatible living kidney transplantation...

KEY POINTS SUMMARY: Type 1 diabetes mellitus increases cardiovascular risk: hypertension amplifies this risk. Pressure natriuresis regulates long-term blood pressure. We induced type 1 diabetes in rats by streptozotocin injection and after three weeks demonstrated a substantial impairment of pressure natriuresis: acute increases in blood pressure did not increase renal medullary blood flow, and tubular sodium reabsorption was not downregulated. Proximal tubule sodium reabsorption, measured by lithium clearance, was unaffected...

Increase in saturated fatty acid (SFA) content in membrane phospholipids dramatically affects membrane properties and cellular functioning. We sought to determine whether exogenous SFA from the diet directly affects the degree of membrane phospholipid unsaturation in adult hearts and if these changes correlate with contractile dysfunction. Although both SFA-rich high fat diets (HFDs) and monounsaturated FA (MUFA)-rich HFDs cause the same degree of activation of myocardial FA uptake, triglyceride turnover, and mitochondrial FA oxidation and accumulation of toxic lipid intermediates, the former induced more severe diastolic dysfunction than the latter, which was accompanied with a decrease in membrane phospholipid unsaturation, induction of unfolded protein response (UPR), and a decrease in the expression of Sirt1 and stearoyl-CoA desaturase-1 (SCD1), catalyzing the conversion of SFA to MUFA...

One of the leading causes of morbidity and mortality in patients with heart failure is right ventricular (RV) dysfunction, especially if it is due to pulmonary hypertension. For a better understanding and treatment of this disease, precise hemodynamic monitoring of left and right ventricular parameters is important. For this reason, it is essential to establish experimental pig models of cardiac hemodynamics and measurements for research purpose. This article shows the induction of ARDS by using oleic acid (OA) and consequent right ventricular dysfunction, as well as the instrumentation of the pigs and the data acquisition process that is needed to assess hemodynamic parameters...

BACKGROUND: CD4+ T cells are key players in regulating the inflammatory processes and physiological repair mechanisms engaged after acute myocardial infarction (AMI). Although signaling through the CD27-CD70 co-stimulatory pathway are known to be important in CD4+ T cell activation and proliferation in certain contexts, the role of the CD27-CD70 pathway in AMI remains unclear. METHODS AND RESULTS: A total of 43 control subjects, 42 unstable angina patients, and 90 AMI patients were enrolled in the present study...

An 8-month-old Hanoverian gelding was presented with a history of cardiac murmurs that were not apparent as a foal nor reported at the time of castration. Major echocardiographic findings included mitral valvular thickening, functional stenosis, and mitral regurgitation of sufficient severity to cause diastolic and systolic cardiac murmurs, left-sided volume overload, and pulmonary hypertension. Due to the hemodynamic severity of the lesion and poor prognosis for future performance and longevity, euthanasia was elected...

Aims: Heart failure (HF) with mid-range ejection fraction (HFmrEF) shares similar diagnostic criteria to HF with preserved ejection fraction (HFpEF). Whether left atrial (LA) function differs between HFmrEF and HFpEF is unknown. We, therefore, used 2D-speckle-tracking echocardiography (2D-STE) to assess LA phasic function in patients with HFpEF and HFmrEF. Methods and results: Consecutive outpatients diagnosed with HF according to current European recommendations were prospectively enrolled...

In diabetic cardiomyopathy, left ventricular (LV) diastolic dysfunction is one of the earliest signs of cardiac involvement prior to the definitive development of heart failure (HF). We aimed to explore the LV diastolic function using electrocardiography (ECG)-gated 18 F-fluorodeoxyglucose positron emission tomography (18 F-FDG PET) imaging beyond the assessment of cardiac glucose utilization in a diabetic rat model. ECG-gated 18 F-FDG PET imaging was performed in a rat model of type 2 diabetes (ZDF fa/fa) and ZL control rats at age of 13 weeks (n = 6, respectively)...
