What is the pro-pnb test and what is the effect on our body if our pro pnb is above the limit?
Dec 12, 2014

Dr. Zakia Dimassi Pediatrics
BNP or pro-BNP may be used to help detect, diagnose, and evaluate the severity of heart failure. This test is ordered if a person has symptoms such as swelling in the legs (edema), difficulty breathing, shortness of breath, and fatigue. It can be used, along with other cardiac biomarker tests, to detect heart stress and damage and/or along with lung function tests to distinguish between causes of shortness of breath. Chest X-rays and an ultrasound test of the heart (echocardiography) may also be done in parallel.
Heart failure can be confused with other conditions, and it may co-exist with them. BNP and NT-proBNP levels can help your doctor distinguish between heart failure and other problems, such as lung disease.
A BNP or NT-proBNP test may be ordered under these circumstances:
- If a person has symptoms that could be due to heart failure.
- If a person is in crisis and/or has symptoms that could be due to heart failure and doctors need to quickly determine if a person is suffering from heart failure or some other medical problem.
- To follow up on treatment effectiveness in cases of heart failure

Higher-than-normal results suggest that a person has some degree of heart failure, and the level of BNP or NT-proBNP in the blood is related to its severity. Higher levels of BNP or NT-proBNP are often associated with a worse prognosis for the person.
Normal results indicate that the person's symptoms are likely due to something other than heart failure.

BNP and NT-proBNP levels are expected to decrease in most people who are taking drug therapies for heart failure, such as ACE inhibitors, beta blockers, and diuretics, whereas they are known to increase with age, or in persons with kidney disease.
Although BNP is usually used to recognize heart failure, an increased level in people with acute coronary syndrome (ACS) indicates an increased risk of recurrent events. Thus, a doctor may use BNP to evaluate risk of a future cardiac event in someone with ACS.
