FN: Chronic Heart Failure Flashcards
1
Q
Diagnosis of CCF
A
Famingham Criteria
2 major criteria or 1 major + 2 minor
2
Q
Major criteria
A
PND \+ve abdominojugular reflux Neck vein distension S3 Basal creps Cardiomegaly Acute pulmonary oedema Increase CVP (>16cm h20) Wt. oss >4.5 kg in 5d secondary to treatment
3
Q
Minor criteria
A
Bila ankle oedema SOBOE Increased HR >120 Nocturnal cough Hepatomegaly Pleural effusion 30% reduced vital capacity
4
Q
Investigations
A
Bloods
CXR
ECG
Echo
5
Q
Bloods included
A
FBC U ad E TFTs Glucose lipids BNP or NTproBNP
6
Q
CXR
A
ABCDE A - alveolar shadowing Kerly B lines Cardiomegaly (cardiothoracic ratio >50%) Upper lobe Diversion Effusions Fluid in the fissures
7
Q
ECG
A
Ischaemia
Hypertrophy
AF
8
Q
Echo
A
The key investigation
- Global systolic and diastolic function - ejection fraction normally - 60%
- Focal/global hypokinesia
- Hypertrophy
- Valve lesions
- Intracardiac shunts
9
Q
B-ype Natriuretic Peptide: BNP or NtproBNP secreted from
A
Ventricles in response to Increase pressure - stretch Tachycardia Glucocorticoids Thyroid hormones
10
Q
B-ype Natriuretic Peptide: Actions
A
- Increase GFR and reduced renal Na reabsorption
2. Redcued preload by relaxing smooth muscle
11
Q
BNP is a biomaker of
A
Heart Failure
12
Q
BNP markers
A
Increased BNP (>100) better than any other variable and clinical judgement in diagnosing heart failure
13
Q
BNP correlates with
A
LV dysfunction
i.e. increase most in decompensated heart failure
Increased BNP = increased mortality
14
Q
BP <100 exlcudes
A
heart failure (96% NPV)
15
Q
BNP also increases in
A
RHF: cor pulmonale, PE
