BACKGROUND The aim of this investigation was to assess the incidence of elevated N-terminal fragment of pro-B-type natriuretic peptide (NT-proBNP) and its relation to outcome defined as perioperative adverse cardiac events and all-cause mortality in high-risk patients undergoing non-elective surgery for hip fracture. METHODS A cohort of patients with hip fractures were extracted from a prospe...
BACKGROUND: The potential cardiotoxicity of antipsychotic drugs is well known. The N-terminal fragment of B-type natriuretic peptide (NT-proBNP) is considered to be a possible biomarker in clinical practice for the diagnosis and prognosis in patients with suspected heart failure. This pilot evaluation tests the influence of antipsychotic drugs on NT-proBNP concentration in view of the hypothesi...
BACKGROUND Preoperative NT-proBNP has been shown to predict adverse cardiac outcomes, although recent studies suggested that postoperative NT-proBNP determination could provide additional information in patients submitted to noncardiac surgery. OBJECTIVE To evaluate the prognostic value of perioperative NT-proBNP in intermediate and high risk cardiovascular patients undergoing noncardiac surg...
OBJECTIVE To determine preoperative ventricular function in vascular amputees by measuring N-terminal pro-brain natriuretic peptide (NT-proBNP) and to analyse the relationship between NT-proBNP levels and 30-day postoperative mortality. DESIGN Prospective pilot study. SUBJECTS AND METHODS In 19 patients planned for a lower limb amputation for non-reconstructable peripheral arterial disease ...
BACKGROUND Brain-type natriuretic peptide (BNP) and the amino-terminal fragment of its prohormone (NT-proBNP) are known predictors of cardiovascular outcomes in patients with coronary heart disease; however, the relative prognostic value of these 2 biomarkers for secondary events remains unclear. METHODS AND RESULTS In 983 participants with stable coronary heart disease, we evaluated the asso...
BACKGROUND Recent studies have shown that plasma levels of the biologically inactive prohormone for brain natriuretic peptide (proBNP) are increased in patients with heart failure. This can contribute to a reduction in the effectiveness of circulating BNP and exacerbate heart failure progression. The precise mechanisms governing the increase in proBNP remain unclear, however. METHODS AND RESU...
BACKGROUND AND OBJECTIVES Recently, the prognostic value of N-terminal brain natriuretic peptide (NT-proBNP) in acute coronary syndrome has been demonstrated in many studies. However, NT-proBNP levels are influenced by various factors such as sex, age, renal function, heart failure severity, and obesity. NT-proBNP concentrations tend to decrease with higher body mass index (BMI). The aim of thi...
BACKGROUND The routine use of natiuretic peptides in severely dyspneic patients has recently been called into question. We hypothesized that the diagnostic utility of Amino Terminal pro Brain Natiuretic Peptide (NT-proBNP) is diminished in a complex elderly population. METHODS We studied 502 consecutive patients in whom NT-proBNP values were obtained to evaluate severe dyspnea in the emergenc...
The aim of this study was to determine how body mass index (BMI) influences the N-terminal pro-B-type natriuretic peptide (NT-proBNP) level in patients with significant coronary artery disease (CAD). A total of 348 patients (61.5 +/- 9.2 years, male 67.5%) who had normal left ventricular systolic function were enrolled. All patients underwent percutaneous coronary intervention. We excluded pati...
INTRODUCTION AND OBJECTIVES NT-proBNP is useful in the diagnosis of heart failure and ventricular dysfunction. Left atrioventricular plane displacement (AVPD) is a consolidated index of ventricular function. Our objective was to carry out a multicenter population-based study to establish the relationship between plasma NT-proBNP levels with AVPD values. PATIENTS AND METHOD We studied 215 subj...
