BNP in Heart Failure

� In the Breathing Not Properly Study, a BNP cutoff of 100 pg

⁄mL was 76% specific and 90% sensitive for the diagnosis of

acute HF in patients presenting to the emergency department

with dyspnea.

� In Acute Shortness of Breath Evaluation (BASEL) study

documented that in acute decompensated HF patients

assessment of BNP levels can lead to rapid diagnosis and

early treatment.

� The utility of BNP in gauging the severity of disease has

been documented through its relationship to left ventricular

end-diastolic pressure

� The N-terminal pro-BNP (NT-proBNP), is

released into the circulation and its

measurement has diagnostic and prognostic

value in HF.

� NT-proBNP has been found to be useful in

the evaluation of a patient presenting with

dyspnea in the acute setting

Both BNP and NT-proBNP assays have a high degree of diagnostic accuracy and clinical relevance for both acute and chronic heart

failure.

Causes of elevated natriuretic peptide levels in the

acute setting •acute coronary syndrome

•atrial or ventricular arrhythmias

•pulmonary embolism

•severe chronic obstructive pulmonary disease with elevated right heart pressures,

renal failure, and sepsis

Causes of an elevated natriuretic level in the non-

acute setting •old age (>75 years)

•atrial arrhythmias

•left ventricular hypertrophy

•chronic obstructive pulmonary disease

•chronic kidney disease

Daniels et al. Am Heart J 2006;151:999 –1005.

• Recently midregional pro-atrial natriuretic peptide (MR-pro-ANP) has rendered prognostic significance

• Midregional epitopes of pro-hormones may be more stable to degradation by exoproteases, unlike epitopes in the N- or C-terminals of pro-ANP used in previous immunoassays.

• In patients after acute myocardial infarction, a lower readmission rate for HF in those in the lower 3 quartiles of MR-pro-ANP and the highest HF readmission rates in those with both biomarkers (MR-pro-ANP and NT-pro-BNP) elevated in the highest quartile.

•• OtherOther

� Inflammatory mediators have pathogenetic role and

contribute to the progression and clinical

presentation of HF giving rise to the “cytokine

hypothesis” according to which the progression of

HF is due, at least in part, to the destructive action

of pro-inflammatory cytokines

� Levels of TNF-α are related with echocardiographic indexes

of both systolic and diastolic left ventricular function.

� Activated macrophages are the main source of TNF-a

production

� The failing heart can also produce TNF-a, which in excessive

levels can promote left ventricular remodelling and can have

negative inotropic effects

Chrysohoou C et al. Heart Vessels 2009;24(1):22-6.

• Other cytokines implicated in the pathogenesis of

CHF are IL-1 and IL-6.

• Plasma adhesion molecules are increased in patients

with heart failure

• High levels of soluble vascular cell adhesion

molecule-1 and P selectin have been shown to

correlate with the severity of heart failure

� Circulating cytokines may contribute to reduced synthesis

and release of NO

� TNF-a is able to impair the stability of eNOS and to down

regulate eNOS expression

� Inflammatory mediators are also implicated in the

endothelial dysfunction observed in HF as cytokines induce

the production of adhesion molecules from the endothelium,

alter the balance between endogenous vasodilators (such as

NO) and vasoconstrictors (e.g. endothelin-1), causing a state

of vasoconstriction

� CRP has central role in the inflammatory cataract

� Framingham Heart Study shown that patients free

from ischemic heart disease and increase levels of

CRP (serum CRP level ≥5 mg/dL) had 2.8 times

increased risk of development of HF during a

follow-up period of approximately 5 years

compared to subjects with normal CRP levels.

� The ST2 is a member of the interleukin-1

receptor family

� Concentrations of ST2 have been reported to

be elevated in patients with HF.

� Increased ST2 plasma concentrations are

independently and strongly associated with

one-year all-cause mortality in HF.

•• OtherOther

� About 1 g of myocardial mass corresponding to 64 million cells is being lost

per year in the human heart

� Additional myocardial damage from necrosis or apoptosis due to acute or

chronic heart failure is believed to be responsible for higher cardiac troponins

in HF patients.

� Several studies have confirmed the increased levels of cardiac troponins in

patients with acute or chronic HF regardless of the cause (ischemic vs.

nonischemic)

� The presence of plasma troponin in HF patients is considered a condition

associated with poor prognosis in HF according to the European Society of

Cardiology guidelines

� An increase in cardiac troponins may indicate an acute coronary event,

myocarditis or an episode of HF decopensation, thus monitoring of cardiac

troponins is useful in assessing the seriousness of the disease and in directing

the appropriate treatmentKawahara C et al. Am Heart J 2011;162(4):639-45.

•• OtherOther

� MPO is elevated in HF patients, while levels of MPO are positively

correlated with NYHA stage.

� In patients with HF intermediate NT-pro-BNP, MPO has an additive

predictive value on mortality.

� Similarly, a prospective study of 667 patients presenting to the

emergency department with dyspnea concluded that although the

diagnostic accuracy of MPO for acute HF was limited, MPO

concentrations above the lowest tertile (MPO>99 pmol/L) were

associated with significantly increased 1-year mortality and its predictive

value is additive to BNP.

� Recently, it was also shown that combining high sensitivity CRP and

MPO measurements provided distinct and complementary prognostic

value in chronic systolic HF.

•• OtherOther

� Plasma ET-1 concentrations are generally increased in

patients with HF

� Plasma ET-1 appears to be related to the severity of the HF,

correlating positively with NYHA class and plasma

angiotensin II, and negatively with left ventricular ejection

fraction and exercise capacity.

� C-terminal pro-endothelin-1 (CT-proET-1) constitutes a

novel predictor of increased 12-month cardiovascular

mortality in patients with congestive HF. High CT-proET-1

together with high NT-pro-BNP enable to identify patients

with congestive HF and particularly unfavorable outcomes.

� Imbalance between the activity of MMPs and their tissue inhibitors

(TIMPs) contribute to myocardial remodeling.

� MMP-2 and -9 levels were significant predictors of diastolic HF in

hypertensive patients.

� TIMPs, are also elevated in HF patients.

� Levels of TIMP-1 were predictive of diastolic HF in hypertensive

patients

� Although, absolute values of MMPs and TIMPs are of prognostic

significance in HF patients sometimes their ratio is more important.

Serum MMP-1/TIMP-1 ratio was inversely correlated with ejection

fraction and directly correlated with left ventricular end-diastolic

diameter in hypertensive HF subjects.

� A variety of biomarkers reflecting different pathophysiologic

states of HF syndrome and different stages in the progression

of the disease have been evaluated for their ability to predict

morbidity, mortality and future cardiovascular events in HF

patients.

� Only NP and cardiac troponins are used in clinical practice

as the majority of the rest biomarkers are not easily available,

are expensive, or their predictive value is low.

� In addition future research in the combination of several

biomarkers is needed to strengthen the predictive value of

established biomarkers in HF patients.
