Risk factors Symptoms Signs Investigations Differential Diagnosis Referral Treatment Risk Factors

Smoking DM Obesity Alcohol High total chol:HDL ratio LVH on echo Congenital heart defects

Valvular disorders in elderly Viral myocarditis Family history Drug related Symptoms LVF SOB, Orthopnoea, PND

Decreased exercise tolerance Lethargy Nocturnal cough Wheeze RVF Swelling of ankles Abdominal discomfort due to liver distension

Nausea and Anorexia Fatigue and Wasting Increased weight NYHA Class Class I (Mild) Class II (Mild) Class III (Moderate) Class IV (Severe) Patient Symptoms

No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation, or dyspnoea (shortness of breath). Slight limitation of physical activity. Comfortable at rest, but ordinary physical activity results in fatigue, palpitation, or dyspnoea. Marked limitation of physical activity. Comfortable at rest, but less than ordinary activity causes fatigue, palpitation, or dyspnoea. Unable to carry out any physical activity without discomfort. Symptoms of cardiac insufficiency at rest. If any physical activity is undertaken, discomfort is increased.

FBC, TFT, E&E, creatinine, eGFR, LFTs, glucose and lipids Urinalysis, peak flow, spirometry Echo Natriuretic Peptides Measurement of natriuretic peptide levels helps to determine: The likelihood of the presence of heart failure. The need for referral for specialist assessment and confirmation of the diagnosis by echocardiography. The urgency of the referral. Natriuretic Peptides Two types of natriuretic peptide can be measured: B-type natriuretic peptide (BNP) and N-terminal pro-BNP (NT-proBNP) (Local Lab uses NT-pro-BNP).

NT-proBNP is the inactive prohormone of BNP and is secreted from the ventricles in response to volume expansion and pressure overload (as occurs in heart failure). BNP increases renal excretion of sodium (natriuresis) and water (diuresis) and relaxes vascular smooth muscle, which leads to vasodilation. Natriuretic Peptides Increased levels of BNP or NT-proBNP are present in: left ventricular hypertrophy, myocardial ischaemia, atrial fibrillation, pulmonary hypertension, hypoxia, pulmonary embolism, right ventricular strain, chronic obstructive pulmonary disease, liver failure, sepsis, diabetes, and renal impairment, in people older than 70 years of age and in

women. Levels are lower in people who are obese or are taking drug treatments, such as aldosterone antagonists, angiotensinconverting enzyme inhibitors, angiotensin-II receptor antagonists, beta-blockers, and diuretics. Referral Refer urgently (within 2 weeks) for specialist assessment and echocardiography: People who have had a previous myocardial infarction (MI). People without a history of MI who have high levels of natriuretic peptide N-terminal pro-B-type natriuretic peptide (NT-proBNP) level above 2000 pg/mL (236 pmol/L). People with severe symptoms (if admission is not indicated). Women who are pregnant.

Referral Refer within 6 weeks: People without a history of MI who have a NT-proBNP level between 4002000 pg/mL (47236 pmol/L). If natriuretic peptide levels are normal (NT-proBNP less than 400 pg/mL [47 pmol/L]), a diagnosis of heart failure is unlikely. However, referral may still be needed if: Clinical suspicion of heart failure persists and the person is obese or taking drugs which lower natriuretic peptide levels (diuretics, angiotensin-converting enzyme inhibitors, angiotensin-II receptor antagonists, beta-blockers, or aldosterone antagonists). Another condition is suspected, which requires referral to a

specialist. Differential dx Obesity Respiratory disease

1. ACE-I /ARB 2. beta blockers. How should I manage the person while they are waiting to see a specialist? If possible, stop any drugs that may affect the person's heart failure, such as nonsteroidal anti-inflammatory drugs (including those bought over the counter) or calcium-channel blockers. If symptoms are sufficiently severe to warrant treatment (but not admission), start a loop diuretic: Furosemide 20 mg/day to 40 mg/day. Bumetanide 0.5 mg/day to 1.0 mg/day. Torasemide 5 mg/day to 10 mg/day.

Seek specialist advise for pregnant women before initiating any drug treatments. Complications Arrythmias Stroke

DVT/PE Malabsorption Hepatic congestion Muscle wasting Angela Graves MSc BSc RN Heart Failure Nurse Manager/Nurse Practitioner East Lancashire Heart Failure Nursing Service East Lancashire Hospitals NHS Trust The impact of heart failure The National Heart Failure Audit Report (2010) suggests that heart failure affects one in every hundred here in the UK with this figure rising steeply for those over 75

years to 7%. Cost to the National Health Service of heart failure is approximately 625 million, predominantly due to emergency admissions. NICE (2010) argue that with appropriate diagnosis, treatment and management morbidity and mortality can be greatly improved. Prognosis Prognosis is poor on the whole, with approximately 50% of people with heart failure dying within four years of diagnosis. Within a year of admission to hospital 32% of patients will die The mortality rate in the UK appears to be improving. A

UK study found that the six-month mortality rate for people with heart failure had improved from 26% in 1995 to 14% in 2005. The prognosis for people with heart failure and preserved left ventricular ejection fraction is a little better than the prognosis for people with heart failure and reduced ejection fraction.
