Clinical Biomarkers of Cardiac Injury: Cardiac Troponins and Natriuretic Peptides

Cardiac natriuretic peptides for cardiac health.

The cardiac natriuretic peptides, ANP (atrial natriuretic peptide) and BNP (brain natriuretic peptide), are secreted by the heart in proportion to cardiac transmural pressures. They possess a wide range of effects in multiple tissues facilitating overall pressure/volume homoeostasis. The close relationship between plasma concentrations of these peptides and 'cardiac load' has led to their use a...

Cardiac troponins.

Cardiac troponins

Objective: To review the use of cardiac troponins as biomarkers for myocardial injury in human and veterinary medicine. Data sources: Data sources included scientific reviews and original research publications. Human data synthesis: Cardiac troponins have been extensively studied in human medicine. Finding an elevated cardiac troponin level carries important diagnostic and prognostic informatio...

Natriuretic peptides in cardiac and renal failure

linkage essential for receptor binding. ANP and BNP are cardiac hormones mainly secreted from the atrium and the ventricle respectively, whereas CNP is of endothelial origin. ANP and BNP bind to the natriuretic peptide A-receptor (NPR-A) and mediate the biological actions of natriuresis, vasodilatation and renin inhibition. In contrast, CNP lacks renal actions but causes vasodilatation via bind...

Cardiac Natriuretic Peptides, Hypertension and Cardiovascular Risk

Prevalence of cardiovascular (CV) disease is increasing worldwide. One of the most important risk factors for CV disease is hypertension that is very often related to obesity and metabolic syndrome. The search for key mechanisms, linking high blood pressure (BP), glucose and lipid dysmetabolism together with higher CV risk and mortality, is attracting increasing attention. Cardiac natriuretic p...
