OBJECTIVE N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a marker of cardiac dysfunction and has been linked to various indices of large vessel disease. However, it remains unclear whether NT-proBNP also relates to microvascular damage. In a community-dwelling population, we studied the association between NT-proBNP and retinal microvascular damage. APPROACH AND RESULTS From the pop...
سابقه و هدف: با توجه به شیوع و روند رو به افزایش مراجعه بیماران با تنگی‌نفس و ابتلای آنها به نارسایی قلبی، در دسترس نبودن همیشگی اکو خصوصاً در مراقبت اولیه، عدم امکان انجام دقیق اکوکاردیوگرافی در بعضی شرایط جسمانی بیمار و مطرح شدن مارکر NT-ProBNP در تشخیص نارسایی قلبی در این افراد، این تحقیق به منظور تعیین ارزش تشخیصی NT-ProBNP نسبت به اکوکاردیوگرافی در تشخیص نارسایی قلبی در بیمارستان شهید مدرس ...
We examined the effect of renal dysfunction on B-natriuretic peptide (BNP), N-terminal (NT)-proBNP, and their molar ratio at varying severities of cardiac function in 94 Thai patients with chest pain (52 men; 32 women), also measuring creatinine and left ventricular ejection fraction (LVEF). Renal function was classified into 5 stages by estimated glomerular filtration rate. The molar NT-proBNP...
BACKGROUND N-terminal pro-brain natriuretic peptide (NT-proBNP) is associated with an increased risk of cardiac insufficiency, which possibly leads to heart failure. However, the relationship between resting heart rate and NT-proBNP is unclear. OBJECTIVE This study focuses on this relativity between resting heart rate and plasma NT-proBNP levels in a surveyed community-based population. MET...
INTRODUCTION Several reports confirmed the prognostic value of the N-terminal fragment of B-type natriuretic peptide prohormone (NT-proBT) in various patient populations. Patients with medical indications for implantation of an artificial cardiac pacemaker are at high risk of cardiovascular events. There is limited data assessing the prognostic value of NT-proBNP in this group. OBJECTIVES The...
BACKGROUND High circulating concentrations of N-terminal fragments of A- and B-type natriuretic peptides (NT-proANP and NT-proBNP) identify patients with impaired cardiac function. ProANP-derived peptides are particularly sensitive to increased preload of the heart and proBNP-derived peptides to increased afterload; therefore, combining the information from the ANP and BNP systems into a single...
هدف: مطالعات بالینی حاکی از آن هستند که نوع فعالیت ورزشی ممکن است اثرات متفاوتی بر عملکرد قلب و سلامت آن داشته باشد. اثر ورزشهای قدرتی و استقامتی بر سلامت قلب به‌واسطه پروتئینهای آزادشده از آن به‌درستی مشخص نیست. بنابراین، هدف پژوهش حاضر مقایسه سطح گالکتین-3 و NT proBNP در مردان ورزشکار قدرتی و استقامتی نخبه بود. روش‌شناسی: در تحقیق حاضر 15 اندام‌پرور (میانگین ± انحراف معیار سن 4/1 ± 0/23 و ...
INTRODUCTION N-terminal pro-B-type natriuretic peptide (NT-proBNP) predicts adverse cardiac outcome in patients undergoing vascular surgery. However, several conditions might influence this prognostic value, including anemia. In this study, we evaluated whether anemia confounds the prognostic value of NT-proBNP for predicting cardiac events in patients undergoing vascular surgery. METHODS A d...
OBJECTIVE To analyze the relationship between N-terminal pro-brain natriuretic peptide (NT-proBNP) and renal function, and compare the ability and cut-off thresholds of NT-proBNP to detect chronic heart failure (CHF) and predict mortality in elderly Chinese coronary artery disease (CAD) patients with and without chronic kidney disease (CKD). METHODS The study included 999 CAD patients older t...
