CCF Flashcards
What is dyspnoea?
Refers to a state where the subject is uncomfortably aware of his/her breathing. Associated with reduced lung compliance or increased respiratory rate.
What are features of RHF?
Ascites, peripheral oedema (up to thighs, sacrum and abdominal wall), hepatomegaly, raised JVP, nausea, anorexia, facial engorgement, epistaxis
What are features of LHF?
dyspnoea, PND, orthopnoea, poor exercise tolerance, fatigue, nocturnal cough, wheeze, nocturia, cold peripheries, weight loss
What is the ‘a’ wave in the jugular venous wave
Right atrial contraction
What causes the c wave in the jugular venous wave?
bulging of the tricuspid valve in ventricular systole
What causes the v wave?
increased blood in the RA from venous return
What is a grade 4 murmur?
A loud murmur with a palpable thrill.
When should a follow-up assessment take place following discharge?
within 2 weeks
What tests and imaging are used to diagnose HF? (5)
Blood test - FBC, haematinics, U&E, TFT, glucose, BNP, Trop-I, LFTs ABGs ECG CXR Transthoracic echo
Why is an echo performed?
establish the presence or absence of cardiac abnormalities.
How is acute HF initially managed?
IV diuretic therapy or IV nitrates
When should non-invasive ventilation be offered?
A patient with severe dyspnoea and acidaemia
What is the NICE definition of heart failure?
a complex syndrome that can result from any structural or functional cardiac disorder that impairs the ability of the heart to function as a pump to support a physiological circulation
What is the most common cause of HF?
Ischaemic heart disease
What is systolic failure?
Inability of the ventricle to contract normally, resulting in reduced cardiac output. Ejection fraction (EF) is <40%.
What is diastolic failure?
inability of the ventricle to relax and fill normally, causing increased filling pressures. Typically EF is >45%, this is termed HFpEF (heart failure with preserved EF).
What are the main causes of RV failure?
LVF, pulmonary stenosis, lung disease
What is acute HF?
new-onset acute or decompensation of chronic heart failure characterised by pulmonary and or peripheral oedema
What is chronic HF?
HF that develops or progresses slowly. Venous congestion is common.
What is the scale used for dyspnoea?
NYHA
What is NYHA stage 4?
Symptoms at rest
What is NYHA?
Marked limitation in activity due to symptoms
What is used to diagnose CCF?
Framingham Diagnostic criteria. Two major or one major and two minor required.
What are the major criteria for CCF? (7)
Acute pulmonary oedema, cardiomegaly, hepatojugular reflux, neck vein distension, PND or orthopnoea, rales/crackles, S3 gallop
