atrial natriuretic peptide

Atrial natriuretic peptide, also known as atrial natriuretic peptide or atrial peptide, is mainly synthesized, stored and released by cardiomyocytes, and distributed in peripheral tissues and organs such as heart, pituitary, lung and adrenal gland. Atrial natriuretic peptide is also present in the central nervous system and in some peripheral ganglion cells (the atrial natriuretic peptide in the central nervous system is self-synthesized, not from blood). Atrial natriuretic peptide has the effects of inhibiting vasopressin and angiotensin, and can regulate the release of pituitary hormones and metabolism of catecholamines, diuretic, sodium excretion, dilation of blood vessels, lower blood pressure, etc., and participate in body water and salt metabolism. Conditioning substance. Basic Information Specialist classification: cardiovascular examination classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Tips: Follow the doctor's instructions. Normal value 30 to 70 ng / L (radioimmunoassay). Clinical significance Reduced in hyperthyroidism, atrial fibrillation, uremia after dialysis. Increased in primary hypertension, renal insufficiency, coronary heart disease, myocardial infarction and heart failure, premature beats, cirrhosis, supraventricular tachycardia, cerebral infarction, cerebral hemorrhage, primary aldosteronism. Low results may be diseases: high results of hyperthyroidism in the elderly may be diseases: essential hypertension, myocardial infarction in the elderly In patients with heart failure, the level of atrial natriuretic peptide is positively correlated with the severity of heart failure, and the worse the cardiac function, the higher the atrial natriuretic peptide level. Inspection process Radioimmunoassay. Not suitable for the crowd No taboos. Adverse reactions and risks Risk of infection: If you use an unclean needle, you may be at risk of infection.
