Chronic HF Flashcards
What is the main clinical sign in chronic heart failure?
Pulmonary eodema
What is HFrEF and HFpEF?
Heart failure with reduced ejection fraction = when the ejection fraction is less than 50%.
Heart failure with preserved ejection fraction = when someone has the clinical features of heart failure but an ejection fraction greater than 50%. This is the result of diastolic dysfunction, where there is an issue with the left ventricle filling with blood during diastole (the ventricle relaxing).
What are the causes of chronic HF? (5)
• Ischaemic heart disease
• Valvular heart disease (commonly aortic stenosis)
• Hypertension
• Arrhythmias (commonly atrial fibrillation)
• Cardiomyopathy
What are the key symptoms of chronic HF? (6)
• Breathlessness, worsened by exertion
• Cough, which may produce frothy white/pink sputum
• Orthopnoea, which is breathlessness when lying flat, relieved by sitting or standing (ask how many pillows they use)
• Paroxysmal nocturnal dyspnoea (more detail below)
• Peripheral oedema
• Fatigue
What signs on examination are seen in chronic HF? (8)
• Tachycardia (raised heart rate)
• Tachypnoea (raised respiratory rate)
• Hypertension
• Murmurs on auscultation indicating valvular heart disease
• 3rd heart sound on auscultation
• Bilateral basal crackles (sounding “wet”) on auscultation of the lungs, indicating pulmonary oedema
• Raised jugular venous pressure (JVP), caused by a backlog on the right side of the heart, leading to an engorged internal jugular vein in the neck
• Peripheral oedema of the ankles, legs and sacrum
What symptom would a patient describe if they have paroxysmal nocturnal dyspnea?
suddenly waking at night with a severe attack of shortness of breath, cough and wheeze.
may describe having to sit on the side of the bed or walk around the room, gasping for breath. They may feel suffocated and want to open a window to get fresh air. Symptoms improve over several minutes.
What are the 3 possible causes of paroxysmal nocturnal dyspnea?
Fluid settling across lungs
Respiratory centres in brain become less responsive
Less adrenalin therefore reduced cardiac output
What are the 3 main investigations in chronic HF?
ProBNP
ECG
ECHO
What is the New York heart association classification?
used to grade the severity of symptoms related to heart failure
What is class I of the New York heart association classification?
No limitation on activity
What is class II of the New York heart association classification?
Comfortable at rest but symptomatic with ordinary activities
What is class III of the New York heart association classification?
Comfortable at rest but symptomatic with any activity
What is class IV of the New York heart association classification?
Symptomatic at rest
What are the 5 principles of management of chronic HF?
• R – Refer to cardiology
• A – Advise them about the condition
• M – Medical treatment
• P – Procedural or surgical interventions
• S – Specialist heart failure MDT input, such as the heart failure specialist nurses, for advice and support
Patient has chronic heart failure and BNP is between 400-2000. When should they have their echo?
Within 6 weeks
