NT-proBNP levels of 95 pregnant women (severe preeclampsia [n = 26], mild preeclampsia [n = ...

Elevated B-type natriuretic peptide (BNP) is a marker of poor outcomes in heart failure, acute coronary syndromes, and sepsis. Elevated cardiac troponin I (cTnI) is associated with adverse outcomes in infective endocarditis. It was hypothesized that elevated BNP would be associated with increased rates of morbidity and mortality in patients ...

Current guidelines recommend right heart catheterisation (RHC) in symptomatic patients at risk of pre-capillary pulmonary hypertension (PH) with echocardiographic systolic pulmonary artery pressures ≥36 mmHg. Growing awareness for PH, a high prevalence of post-capillary PH and the inability to distinguish between pre- and post-capillary PH by echocardiography have led to ...

Recently, concerns have been raised about a possible lack of sensitivity of biomarkers to detect left ventricular (LV) dysfunction in patients with myopathies. We examined the ability of the N-terminal brain natriuretic peptide (NT-proBNP) to detect LV or right ventricular (RV) dysfunction in patients with lamin A/C (LMNA) gene mutations. ...

Dyspneic emergency department (ED) patients present a diagnostic dilemma. The S3, although highly specific for acute heart failure (AHF) and predicting death and readmission, is often difficult to auscultate. The HEart failure and Audicor technology for Rapid Diagnosis and Initial Treatment (HEARD-IT) multinational trial evaluated the S3 via acoustic cardiography ...

Aneuploidy is a very common prognostic factor in multiple myeloma (MM). Nonhyperdiploidy including near-tetraploidy (NT) is a poor prognostic indicator, compared to hyperdiploidy in multiple myeloma (MM). NT results from endoduplication of hypodiploidy. We report of a 55-year-old female patient diagnosed with advanced stage MM with hyperdiploidy and t(8;14)(q24;q32). The ...

To assess the role of cardiac troponin T (cTnT) levels on admission using a new, highly sensitive assay (hsTnT) in the risk assessment of normotensive patients with acute pulmonary embolism (PE). We prospectively studied 156 consecutive normotensive patients with confirmed PE. The prognostic value of hsTnT at baseline was compared ...

Diastolic dysfunction in patients with heart failure has prognostic relevance, possibly because of its relationship with worsening haemodynamic status. In the quest for simpler indexes of haemodynamic status in patients, brain natriuretic peptide (BNP) levels have been proposed as a surrogate of diastolic function. To date, the value of combining ...

It is still unclear whether circulating levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP) reflect cardiac filling and function in the critically ill patient, particularly during sepsis and a proinflammatory response that may induce NT-proBNP release from the heart. We prospectively evaluated the value of NT-proBNP as a marker of cardiac ...

REVEAL (the Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management) is the largest US cohort of patients with pulmonary arterial hypertension (PAH) confirmed by right-sided heart catheterization (RHC), providing a more comprehensive subgroup characterization than previously possible. We used REVEAL to analyze the clinical features of patients ...

Elevated brain natriuretic peptide (BNP) and tumour marker antigen carbohydrate 125 (CA125) levels have shown to be associated with higher risk for adverse outcomes in patients with acute heart failure (AHF). Nevertheless, no attempt has been made to explore the utility of combining these two biomarkers. We sought to assess ...

Pseudoaneurysms are characterized by extravascular circulation and therefore may lead to an activation of the coagulation cascade. We investigated d-dimer levels in patients with and without postcatheterization femoral pseudoaneurysms and hypothesized that d-dimer levels correlate with the presence of pseudoaneurysms at the vascular access site. Patients with clinical suspected groin ...

Pulmonary hypertension (PH) is a common complication of haemolytic anaemia. Intravascular haemolysis leads to nitric oxide (NO) depletion, endothelial and smooth muscle dysregulation, and vasculopathy, characterized by progressive hypertension. PH has been reported in patients with paroxysmal nocturnal haemoglobinuria (PNH), a life-threatening haemolytic disease. We explored the relationship between haemolysis, ...
