Heart Failure
Investigation And Management
By: Ismah Haron
Diagnosis
• Framingham criteria• Simultaneous presence of at least 2
major criteria or 1 major criterion plus 2 minor criteria.
Framingham criteria
PND Acute pulmonary edema JVP Hepatojugular reflux S3 gallop Crackles in lung fields Cardiomegaly on CXR CVP (>160 cmH2O at RA) Weight loss >4.5 kg in 5
days in response to Rx of HF
Major Nocturnal cough Dyspnea on ordinary
exertion Bilateral ankle edema Tachycardia (HR >120/min) Hepatomegaly Pleural effusion Decrease in vital capacity
by 1/3rd
Minor
Quiz
• For Framingham criteria: simultaneous presence of at least ……. or …… plus ……..
ECG
• No specific changes• AF • Tachy / bradyarrhythmias• Previous MI • Cardiac ischemia • Ventricular hypertrophy
Plasma BNP
• Secreted by ventricular myocardium• Closely related to LV pressure • Reflect myocyte stretch • Highest in decompensated heart failure • Diagnosis of HF if BNP >100ng/L
CXR
Alveolar oedema (Bat’s
wing)
Kerley B line
Pleural Effusion
Dilated prominent upper
lobe vessel
Cardiomegaly
Echocardiogram
• Resting LV size and function• Absence/presence of LV dysfunction• To detect valvular disease, pericardial
or myocardial disease
Acute managementSit the patient
uprightO2 100%
IV access and monitor ECG.
Treat any arrhythmias
Ix whilst continuing treatment
Diarmorphine 2.5 to 5mg IV
slowly.
Furosemide 40-80mg IV
slowly
GTN spray 2 puffs SL or 2 X 0.3mg tablets
SL
Necessary ix, examination and history
If BP ≥100mmHg, start nitrate
infusion If SBP
<100mmHg treat as
cardiogenic shock
Management outline • Confirm diagnosis• Ascertain the severity of symptoms and
presenting features• Determine the etiology of HF• Identify the exacerbating factors and any
concomitant illness• Estimate prognosis• Anticipate complications• Counsel patient and relatives• Choose appropriate management• Monitor progress and manage accordingly
Chronic management
• Change in lifestyle: smoking. Salty foods. Weight and nutrition.
• Treat the cause• Treat exacerbating factors• Avoid exacerbating factors• Drugs
QuizFollowing is/are true regarding heart failure:
A. Framingham criteria can be used to diagnose HF
B. Hepatomegaly is the major point in Framingham criteria
C. CXR in HF will shows dilated prominent lower lobe vessels
D. The higher the BNP, the lower the cardiovascular mortality
E. Usage of Digoxin is absolutely contraindicated in heart failure
