Systolic heart failure Flashcards
Anatomical structures
usually LV- but can be RV
Structural abnormalities
Ventricles often dilated due to heart’s attempt to pump more blood
Valve regurgitation
Mitral or tricuspid valve regurgitation may result from ventricular dilation due to stretching of the valve ring
Physiological abnormalities
Heart loses ability to pump enough blood
The heart loses its pumping reserve
Prior events
Most common: MI
Viral myocarditis
Chemotherapy
Experienced symptoms
Tiredness, breathlessness (dyspnoea),
breathlessness when lying flat (orthopnoea),
sudden breathlessness in the night (paroxysmal nocturnal dyspnoea),
passing excess urine at night (Nocturia),
ankle swelling
signs
Tachypnoea (rapid respiration), oedema, high jugular venous pressure Tachycardia Hypotension Cachexia (loss of skeletal muscle mass) Anorexia
Abnormal test results
Echocardiogram- dilated heart chambers which contract weakly- valves may be leaky
Blood test of hormone BNP (Brain Natiuretic Peptide) raised
ECG abnormal due to underlying problem
Medical/ surgical intervention
Weigh themselves daily- detect changes in fluid retention
Loop diurectic e.g. furosemide
Potassium retaining diuretic e.g. spironolactone
ACE-inhibitor e.g. ramipril
Beta blocker
Some patients- special pacemaker that ‘resynchronises’ the R and L ventricle systolic contraction
