Background Physiology Uses of NT-proBNP Case discussions Conclusions Questions Presentation
Heart Failure Common condition with high morbidity and mortality. Leads to hospital admissions and readmissions Can be difficult to diagnose Evidence based treatment available for heart failure which help improves symptoms, prognosis and reduces hospital admissions
Symptoms and Signs of Heart Failure Typical symptoms: Dyspnoea, Fatigue, Oedema Typical signs: Raised JVP, Displaced Apex Beat, Gallop Rhythm, Crepitations, Effusions, Hepatomegaly, Ascites, and Oedema
NICE Chronic Heart Failure Guidelines Chronic heart failure: management of chronic heart failure in adults in primary and secondary care Clinical guidelines, CG108 - Issued: August 2010 http://www.nice.org.uk/cg108
Key steps for better HF outcomes Early and accurate diagnosis Mechanism of heart failure Prompt and appropriate treatment Optimising treatment Monitoring
NICE HF cost savings per 100, 000 patients using BNP
Heart Failure costs In 2002, 716 million (1.8% of total NHS budget) Hospital in-patient stay 250 per day Echocardiography 60 Cardiology out-patient 160 NT-proBNP 20

HF treatment available for East Suffolk Advice & Support: Heart Failure & Rehab team Medication: Diuretics, ACE inhibitors, ARBs, B-blockers, Aldosterone antagonists, Digoxin, Ivabradine, Hydralazine, Nitrates Devices: ICD, CRT-P, CRT-D
HF treatment available for East Suffolk Cardiac Intervention and Surgery: PCI, CABG, Valvular Surgery Advanced Heart Failure: Inotropes, Haemofiltration, LVAD, Artificial Heart, Transplant End stage Heart Failure: Palliative care
The heart as an endocrine organ An endocrine organ secrete hormones directly into the circulatory system to be carried towards a distant target organ Natriuretic Peptides released by the heart Causes vasodilatation, diuresis and sodium excretion Pro Atrial Natriuretic Peptide Pro Brain Natriuretic Peptide
BNP and NT-proBNP
Brain Natriuretic Peptide Released by the ventricular myocardium in response to increased intracardiac volume and/or pressure BNP secretion controlled at the transcription level so sustained stimulus is required Causes include LVSD, volume overload, LVH, and ischaemia BNP levels increase with age and renal failure
Brain Natriuretic Peptide BNP levels higher than normal in patients with HF BNP levels decrease with diuretics and ACE Inhibitors. BNP levels initially increase with B-Blockers and then decrease. BNP levels decrease with spironolactone and ARBs
Diagnosing HF with BNP In one study a NT probnp of 300pg/ml: Sensitivity 94% Specificity 61% Positive Predictive Value 44% Negative Predictive Value 97% Therefore an excellent rule out test Improves diagnostic accuracy
HF prognosis and monitoring with BNP Higher the BNP levels the worse the prognosis. Helps identifies patients at most concern. BNP levels fall as HF treated. Levels can be rechecked for exacerbations of HF.
History: HF Clinical Evaluation To formulate diagnosis and to monitor response to treatment Age, Gender, Ethnicity, Symptoms (inc. Duration and Severity), PMH of IHD or HTN, Respiratory Disease, Medication, Allergies, Smoker? Alcohol?, Family history of IHD or Cardiomyopathy
Aetiology of Heart Failure Heart Failure can occur due to many different causes. Identification of the cause guides treatment.
Causes of Heart Failure Ischaemic heart disease (most common cause) Hypertensive heart disease Cardiomyopathy (Dilated, Hypertrophic, Restrictive, Peripartum) Valvular heart disease Congenital Heart Disease Arrhythmia
Causes of Heart Failure Viral and other infection (Chagas disease) Alcohol and Drugs Chronic lung disease (Cor Pulmonale/Pulmonary Hypertension) Pericardial Disease Hyperdynamic Circulation disease (Anaemia, Thyrotoxicosis, AV malformations) Connective Tissue Disease
Medical Treatment of LVSD HF Loop Diuretics: Improve symptoms Frusemide and Bumetanide ACE inhibitors: Improves symptoms and prognosis. Maximise dose Ramipril, Perindopril, Lisinopril ARBs: Improves symptoms and prognosis. Maximise dose. Candesartan, Losartan, Valsartan B-Blockers: Improves symptoms and prognosis. Maximise dose. Bisoprolol, Carvedilol, Nebivolol, and Metoprolol CR/XL
Medical Treatment of LVSD HF Spironolactone and Eplerenone: Improves symptoms and prognosis. Hydralazine and Nitrate: Improves symptoms and prognosis. Up-titrate dose. In place of ACE inhibitors/arbs in Renal Failure Ivabradine: Reduces Hospitalisation. In Sinus rhythm >70/min and B-blocker intolerant/insufficient. Digoxin: Reduces Hospitalisation. In Sinus rhythm or AF and B-blocker intolerant/insufficient.
Classification of HF symptom severity New York Heart Association(Little, Brown & Co; 1994) Class 1: previous symptoms now no limitation with ordinary activity, Class 2: slight limitation with activity, Class 3: marked limitation with activity, Class 4: symptoms at rest or unable to carry out any activity without symptoms.
Treatment of LVSD HF in NYHA Class 1 Beta blockers (Metoprolol, Carvedilol, Bisoprolol, Nebivolol), ACE inhibitors, and Angiotensin receptor blockers (Candesartan, Losartan, and Valsartan). Maximise beta blocker and ACE inhibitor to highest tolerated dose.(heart rate >55, Blood pressure >90mmHg systolic)
Treatment of LVSD HF in NYHA Class 2 Loop Diuretics, Beta blockers, ACE inhibitors, ARBs, Eplerenone (EF<30%), Digoxin Ivabradine (EF<35%, HR>70, sinus), ICD (EF<35%), CRT-D (EF<35% & QRS>120ms),
Treatment of LVSD HF in NYHA Class 3 Loop Diuretics, Beta blockers, ACE inhibitors, ARBs, Spironolactone (EF<35%), Digoxin, Metolazone, Hydralazine and Nitrate, ICD (EF<35%), CRT-D (EF<35% & QRS>120ms),
Treatment of LVSD HF in NYHA Class 4 Loop Diuretics, Beta blockers, ACE inhibitors, ARBs, Spironolactone (EF<35%), Digoxin, Metolazone, Hydralazine and Nitrate (EF<35%), CRT-P (EF<35% & QRS>120ms), (Inotropes, LVAD, Artificial Heart, Heart Transplant) Palliative Care
