INTRODUCTION Monitoring treatment efficacy and assessing outcome by serial measurements of natriuretic peptides in acute decompensated heart failure (ADHF) patients may help to improve outcome. METHODS This was a prospective multi-center study of 171 consecutive patients (mean age 80 73-85 years) presenting to the emergency department with ADHF. Measurement of BNP and NT-proBNP was performed ...
BACKGROUND It is unclear whether coronary artery stenosis affects the secretion of N-terminal pro-brain natriuretic peptide (NT-proBNP) and brain natriuretic peptide (BNP) from the heart independent of ventricular dysfunction. Therefore, this study evaluated the relationship between BNP and NT-proBNP secretion, plasma levels and the severity of coronary artery stenosis in patients with stable c...
AIM Cardiac troponins and natriuretic peptides are established for risk stratification in light-chain amyloidosis. Data on cardiac biomarkers in transthyretin amyloidosis (ATTR) are lacking. METHODS AND RESULTS Patients (n = 1617) with any of the following cardiac biomarkers, BNP (n = 1079), NT-proBNP (n = 550), troponin T (n = 274), and troponin I (n = 108), available at baseline in the Tran...
سابقه و هدف: با توجه به فراوانی بیماران مبتلا به نارسایی قلبی با روند رو به افزایش و عوارض و پیامدهای شناخته شده این بیماری و اهمیت شاخص های نشان دهنده تشخیص و درمان و پیش آگهی بیماران و وجود گزارش های مبنی بر تغیرات میزان پلاسمائی nt- pro bnp در این گروه از بیماران و نیز عدم گزارشی از تجربه آن در کشور این تحقیق بر روی بیماران نارسایی قلبی مراجعه کننده به بیمارستان طالقانی انجام شد. مواد و روش ...
BACKGROUND The role of N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) as a prognostic factor in patients admitted to the intensive care unit (ICU) is not yet fully established. We aimed to determine whether NT-pro-BNP is predictive of ICU mortality in a multicenter cohort of critically ill patients. METHODS A total of 1440 patients admitted to 22 ICUs (medical, 14; surgical, six; mult...
BACKGROUND We compared the diagnostic accuracy of brain natriuretic peptide (BNP) and amino-terminal proBNP (NT-proBNP) for diagnosis of preclinical and mild heart failure (HF). METHODS We assayed plasma NT-proBNP and BNP in 182 healthy controls and in a prospective cohort of 820 HF patients divided according to the American Heart Association/American College of Cardiology classification. The...
BACKGROUND We investigated the relationship between NT-pro-BNP, glomerular filtration rate (GFR), and all-cause mortality rates in a cohort of older people discharged from an internal medicine unit after admission for dyspnoea. PATIENTS AND METHODS NT-pro-BNP was evaluated in serum samples of 134 patients aged 80 ± 6 years who presented to a single academic centre with worsening dyspnoea. His...
Previous reports have shown that N-terminal pro-brain natriuretic peptide (NT-Pro-BNP) is a predictive marker for mortality in both peritoneal dialysis (PD) and hemodialysis (HD) patients. The aim of the present study was to clarify whether NT-Pro-BNP reflects a specific status in PD patients. We analyzed 40 stable PD patients, allocating them to one of two groups (20 each) according to the med...
BACKGROUND Persistent atrial fibrillation (AF) leads to electrical, structural and neurohormonal remodelling of the atria, including increased plasma B-type natriuretic peptide (BNP) level. AIM To assess the clinical value of plasma BNP or NT-proBNP concentrations in patients with persistent AF measured before and after sinus rhythm restoration following direct-current cardioversion. METHOD...
BACKGROUND AND OBJECTIVES B-type natriuretic peptide (BNP) and amino-terminal pro-B-type natriuretic peptide (NT-proBNP) are biomarkers of cardiovascular disease that is common in patients with chronic kidney disease (CKD). Conflicting data on the influence of glomerular filtration rate (GFR) on BNP and NT-proBNP levels in CKD may stem from failure to account fully for the effects of coexistent...
