70
Why do you do a transthroacic ecocardiogram?
1. Visualise structure and function of heart(can show cause of HF) 2. Can calculate ejection fraction (EF): % of blood present in LV that gets pumped during systole Normal is 50-70%
71
What is HF with EF<40%?
HF with reduced ejection fraction (HFrEF) (previously called systolic HF), indicated inability of ventricle to contract normally)
72
What is HF with EF>50%?
HF with preserved ejection fraction (HFpEF), previously called diastolic HF, indicates inability of ventricle to relax and fill normally
73

75
What is some of the minor criteria?
1. Bilateral ankle oedema 2. Dyspnoea on ordinary exertion 3. Tachycardia 4. Decrease in vital capacity by 1/3 5. Nocturnal cough 6. Hepatosplenomegaly 7. Pleural effusion
76
When do you use diuretics and which ones?
- use if evidence of fluid retention - Loop diuretics e.g. furosemide - Aldosterone antagonists e.g. spironolactone

When do you use hydralazine + nitrates in heart failure?
afro-caribeban patients
78
How does digoxin help with cardiac failure?
positive inotrope (strengthen heart contraction), improve symptoms BUT NOT MORTALITY
79
How is cardiac resynchronisation therapy is used?
aims to improve timings of contraction of atria and ventricles
80
What is the treatment for acute HF?
1. Sit patient upright 2. 60-100% oxygen 3. IV diamorphine 2.5-5mg 4. GTN infusion 5. IV furosemide 40-80mg (can alleviate pulmonary oedema if they have that)
