Cardiac natriuretic peptide (CNP) measurement can provide clinicians with a basis for the pathology and physiology of some diseases (especially cardiovascular diseases), as well as for diagnosis and treatment.
Cardiac natriuretic peptide, also known as atrial natriuretic peptide, is synthesized and secreted by the atria, and has the effects of diuresis and sodium excretion, vasodilatation, and antagonism to the adrenaline, renin-angiotensin-aldosterone system. When the level of cardiac natriuretic peptide is elevated, it often suggests that the patient himself is experiencing cardiac insufficiency and heart failure due to prolonged damage to the heart.
In addition, the degree of elevation of cardiac natriuretic factor is positively correlated with the severity of heart failure, and the plasma level of cardiac natriuretic factor can be used to identify cardiac dyspnea, as well as to assess the effectiveness of treatment for heart failure and to determine the prognosis of heart failure treatment.
If the natriuretic factor is abnormal, the cause of the abnormality should be clarified, and the doctor should provide appropriate treatment.
