Difference Between ANP and BNP

In normal human heart, ANP is mainly synthesized in and secreted from the cardiac atrium, whereas BNP is predominantly in the cardiac ventricle (7–9). In normal human adults, the plasma BNP concentration is 1–2 fmol/ml, which is about one-sixth of the plasma ANP concentration (7–9).

What is ANP and BNP?

ANP and BNP are endogenously generated peptides activated in response to atrial and ventricular volume/pressure expansion. ANP and BNP are released from the atria and ventricles, respectively, and both promote vasodilation and natriuresis. ... ANP and BNP are elevated in chronic heart failure.

What effects do ANP and BNP have?

The major physiological effects of ANP and BNP are vasodilation, natriuresis, and inhibition of the renin-angiotensin-aldosterone (RAA) and the sympathetic nervous systems; all of which are supposed to suppress the progression of heart failure.

What is the function of BNP?

Brain natriuretic peptide (BNP) is a peptide hormone that is released in response to volume expansion and the increased wall stress of cardiac myocytes. BNP helps to promote diuresis, natriuresis, vasodilation of the systemic and pulmonary vasculature, and reduction of circulating levels of endothelin and aldosterone.

What is the difference between BNP and proBNP?

The diagnostic performance of BNP and NT‐proBNP is comparable and there is no meaningful difference between them. They reflect haemodynamic myocardial stress independent of the underlying pathology, thus they are not specific for a distinct pathology such as heart failure but for cardiovascular diseases in general.

What triggers BNP release?

The release of these peptides by the heart is stimulated by atrial and ventricular distension, as well as by neurohumoral stimuli, usually in response to heart failure. The main physiological actions of natriuretic peptides is to reduce arterial pressure by decreasing blood volume and systemic vascular resistance.

What BNP level indicates heart failure?

BNP levels go up when the heart cannot pump the way it should. A result greater than 100 pg/mL is abnormal. The higher the number, the more likely heart failure is present and the more severe it is. Sometimes other conditions can cause high BNP levels.

Is BNP always elevated in heart failure?

Levels goes up when heart failure develops or gets worse, and levels goes down when heart failure is stable. In most cases, BNP and NT-proBNP levels are higher in patients with heart failure than people who have normal heart function.

How does BNP affect blood pressure?

The physiologic actions of BNP are similar to those of ANP and include decrease in systemic vascular resistance and central venous pressure as well as an increase in natriuresis. The net effect of these peptides is a decrease in blood pressure due to the decrease in systemic vascular resistance and, thus, afterload.

What is the effect of atrial natriuretic peptide?

Atrial natriuretic peptide (ANP) is a cardiac hormone that regulates salt-water balance and blood pressure by promoting renal sodium and water excretion and stimulating vasodilation. ANP also has an anti-hypertrophic function in the heart, which is independent of its systemic blood pressure-lowering effect.

What are the 4 signs your heart is quietly failing?

Heart failure signs and symptoms may include:

• Shortness of breath (dyspnea) when you exert yourself or when you lie down.
• Fatigue and weakness.
• Swelling (edema) in your legs, ankles and feet.
• Rapid or irregular heartbeat.
• Reduced ability to exercise.
• Persistent cough or wheezing with white or pink blood-tinged phlegm.

What are the 4 stages of heart failure?

There are four stages of heart failure (Stage A, B, C and D). The stages range from "high risk of developing heart failure" to "advanced heart failure," and provide treatment plans.

How long can you live with high BNP?

The surprising thing is that the short-term and long-term risk of death at an extremely high BNP value were significantly increased: 53.8% mortality in 3 months, 69.2% in 2 years and all patients died in 5 years, which was observably higher than the other groups.
