The heart is unable to pump
blood at a rate that meets the
metabolic requirements of
the peripheral tissue;
inadequate cardiac output is
usually accompanied by
increased congestion of the
relevant venous circulation.
Classification
Left-sided versus right-sided failure
Left ventricular failure and right ventricular failure
can occur independantly or together as congestive
cardiac failure
RVH
LVF
Pulmonary stenosis
Lung disease
Symptoms
Peripheral edema
Ascites
Nausea
Facial engorgement
Pulsation in neck and face
Epistaxis
LVH
Dyspnea
Poor exercise tolerance
fatigue
Orthopnea
PND
Nocturnal cough
Wheeze
Muscle wasting
Weight loss
Cold peripheries
Nocturia
Low-output versus high-output failure
High-output heart failure
Output is normal or
increased with increased
needs. Failure occurs when
cardiac output fails to
meet these needs. Occ- urs
with a normal heart but
ear- lier if there is heart
disease.
Consequence
Initially features of
RVF, then LVF becomes
evident
Causes
Anemia
pregnancy
Hyperthyroidism
Paget's disease
Low-output heart failure
Cardiac output is decreased and fails to
increase normally with exertion.
Causes
Pump failure
Systolic ordistolic
Heart failure
decreased HR
Excessive overload
MR
fluid overload
Chronic excessive after load
AS
Hypertension
Systolic versus diastolic
failure
Systolic failure
Inability of the ventricle to
contract normally, resulting in
decreased cardiac output.
Ejection fraction is <40%.
Causes
IHD
MI
DCM
myocarditis
Diastolic Failure
Inability of the ventricle to
relax and fill normally
causing increased fillinf
pressures. Ejection fraction
> 50%.
Causes
Constrictive pericarditiS
Tamponade
Restrictive cardiomyopathy
Hypertension
Acute versus chronic heart
failure
Acute heart failure
Is often used exclusively to mean
new onset acute or
decompensation of chronic heart
failure characterised by
pulmonary and/or peripheral
edema with or without signs of
peripheral hypoperfusion.
Chronic Heart failure
Develops or progresses
slowly, venous congestion
is common but arterial
pressure is well
maintained until very late.
prognosis
Poor with 25 - 50% of patients dying
within 5 years of diagnosis.
Diagnosis
Routine laboratory Test
biomarkers
Echocardiography
ECG
Recommended test in all heart failure patients.
CXR
Cardiomegaly
Dilated prominent
upper lobe vessels
pleural
effusion
Kerley B lines
Alveolar Edema
Bat wisngs
Interstitial edema
ECG in CHF can show abnormalities as
arrhythmias, ischemia, MI, LVH, conduction
abnormalities such as PVCs, LBBB.
Symptoms
Risk factors
Tobacco use
Hyperlipidemia
Hypercholestremia
Diabetes
Management
Non-pharmacological
Limiting salt intake for all HF patients
Limiting fluid intake for those with
hyponatremia, high diuretics intake
and severe HF
Exercise for those with stable heart
and stable volume levels
Monitoring all HF patients
Pharmacological
Drugs used
Decreased load on the heart
Diuretics
ACE inhibitors
ARBs
Vasodilators
Increase the function of the heart
Beta-blockers
Adrenergics
Inotropic-cardiotonic drugs
Digoxin
Phosphodiestrase inhibitors
Dobutamine
Adrenaline
