Brain natriuretic peptide (BNP), also known as B-type natriuretic peptide, is a hormone secreted by cardiomyocytes in the heart ventricles in response to stretching caused by increased ventricular blood volume. [5] BNP is one of the three natriuretic peptides, in addition to atrial natriuretic peptide and C-type natriuretic peptide . [6]
A pseudothrombocytopenia false-positive result may occur when automated platelet counting devices are used. As a means of double checking the results, the patient's blood sample is often examined under a microscope. If the clumping is visible and the number of platelets appears normal, pseudothrombocytopenia may be concluded.
There is no level of BNP that perfectly separates patients with and without heart failure. [14]In screening for congenital heart disease in pediatric patients, an NT-proBNP cut-off value of 91 pg/mL could differentiate an acyanotic heart disease (ACNHD) patient from a healthy patient with a sensitivity of 84% and specificity of 42%.

An auscultatory gap, also known as the silent gap, [1] is a period of diminished or absent Korotkoff sounds during the manual measurement of blood pressure.It is associated with peripheral blood flow caused by changes in the pulse wave. [2]
Natriuretic peptide-binding receptors and ligand selectivity. [1] A natriuretic peptide is a hormone molecule that plays a crucial role in the regulation of the cardiovascular system. These hormones were first discovered in the 1980s and were found to have very strong diuretic, natriuretic, and vasodilatory effects.
Atrial natriuretic peptide (ANP) or atrial natriuretic factor (ANF) is a natriuretic peptide hormone secreted from the cardiac atria that in humans is encoded by the NPPA gene. [5] Natriuretic peptides (ANP, BNP , and CNP ) are a family of hormone/paracrine factors that are structurally related. [ 6 ]
On the other hand, a PCR test can rarely be a false positive, says Dr. Watkins, but “in an asymptomatic person without known close contact with an infectious individual, especially in a low ...
Unsuppressed ADH causes a physiologically inappropriate increase in solute-free water being reabsorbed by the tubules of the kidney to the venous circulation leading to hypotonic hyponatremia (a low plasma osmolality and low sodium levels). [2] The causes of SIADH are commonly grouped into categories including: central nervous system diseases ...
