Underlying Anatomic Abnormalities Causing Heart Failure

Heart failure may result from an abnormality of any one of the anatomical structures of the heart:

Systolic versus Diastolic Heart Failure

Patients may be broadly classified as having heart failure with depressed contractility or depressed relaxation

Systolic Dysfunction

The left ventricular ejection fraction is reduced in systolic dysfunction and there is depressed contractility of the heart.

Disastolic Dysfunciton

The left ventricular ejection fraction is preserved in diastolic dysfunction and there is an abnormality in myocardial relaxation or excessive myocardial stiffness. Systolic and diastolic dysfunction commonly occur in conjunction with each other.

Left, Right and Biventricular Failure

Another common method of classifying heart failure is based upon the ventricle involved (left sided versus right sided).

Left Heart Failure

  • There is impaired left ventricular function with reduced flow into the aorta.

Right Heart Failure

  • There is impaired right ventricular function with reduced flow into the pulmonary artery and lungs.

Biventricular Failure

  • The most common cause of right heart failure is left heart failure, and mixed presentations are common, especially when the cardiac septum is involved.

High Output Versus Low Output Failure

Low Output Failure

High Output Failure

Causes of Acute or Decompensated Heart Failure

Chronic stable heart failure may easily decompensate. This most commonly results from an intercurrent illness (such as pneumonia), myocardial infarction (a heart attack), arrhythmias, uncontrolled hypertension, or a patient's failure to maintain a fluid restriction, diet, or medication.[4] Other well recognized precipitating factors include anemia and hyperthyroidism which place additional strain on the heart muscle. Excessive fluid or salt intake, and medication that causes fluid retention such as NSAIDs and thiazolidinediones, may also precipitate decompensation.[5]

Differential Diagnosis of the Underlying Causes of Chronic Heart Failure

Common Causes of Left Sided Heart Failure

A 19 year study of 13,000 healthy adults in the United States (the National Health and Nutrition Examination Survey (NHANES I) found the following causes ranked by Population Attributable Risk score:[6]

  1. Ischaemic heart disease 62%
  2. Cigarette smoking 16%
  3. Hypertension (high blood pressure)10%
  4. Obesity 8%
  5. Diabetes 3%
  6. Valvular heart disease 2% (much higher in older populations)

Cardiomyopathies and Inflammatory Diseases

Restrictive Cardiomyopathies
Dilated Cardiomyopathies
Inflammatory Cardiomyopathies

Congestive Heart Failure as a Consequence of Valvular Heart Disease

Congestive Hert Failure Secondary to Congenital Heart Disease

A. Causes of Congestive Heart Failure in Adults with Unoperated Congenital Heart Diseases

B. Causes of Congestive Heart Failure in Adults with Operated Congenital Heart Diseases

Right Ventricular Failure

Factors affected right ventricle and to be eliminated during management of congestive heart failure. A. Right ventricular myocardial dysfunction

  1. Right ventricular myocardial infarction
  2. Dilated cardiomyopathy
  3. Right ventricular dysplasia

B. Primary right ventricular pressure overload

  1. Left ventricular failure
  2. Mitral valve disease
  3. Atrial myxoma
  4. Pulmonary veno-occlusive disease
  5. Cor pulmonale
  6. Pulmonic stenosis
  7. Ventricular septal defect
  8. Aortopulmonary communication

C. Primary right ventricular volume overload

  1. Pulmonic regurgitation
  2. Tricuspid regurgitation
  3. Atrial septal defect
  4. Partial anomalous pulmonary venous return

D. Impediment to right ventricular inflow

  1. Tricuspid stenosis
  2. Cardiac tamponade
  3. Constrictive pericarditis
  4. Restrictive cardiomyopathy
