Heart Failure

Heart Failure is a condition in which heart muscles cannot pump enough blood to meet the body’s requirements. It usually occurs because the heart has become too weak or stiff. It’s sometimes called congestive heart failure.

Causes of Heart Failure

  • Coronary artery disease- In this condition plaque accumulates in the arteries which causes reduced blood flow and can lead to heart attack.
  • Hypertension (High blood pressure)- This can make the heart muscle too stiff or too weak to effectively pump blood.
  • Damaged or diseased heart valves- A damaged valve forces the heart to work harder, which can lead to weakening of heart.
  • Cardiomyopathy- (damage to the heart muscle).
  • Myocarditis (inflammation of heart muscle)- It can lead to left-sided heart failure.
  • Congenital heart defects
  • Diabetes
  • HIV
  • Alcohol & drug use
  • Obesity

Signs & symptoms of Heart Failure

  • Shortness of breath (dyspnea)
  • Fatigue and weakness
  • Swelling in the legs, ankles, feet & abdomen
  • Irregular heartbeat
  • Persistent cough or wheezing
  • Increased need to urinate at night
  • Fluid retention
  • Lack of appetite and nausea
  • Difficulty in concentrating
  • Sudden severe shortness of breath
  • Chest pain

Diagnosis of Heart Failure

  • Blood tests- They are done to look for signs of diseases that can affect the heart.
  • Chest X- ray- It helps the doctor to see condition of the lungs and heart.
  • Electrocardiogram (ECG)- This test records the electrical activity of the heart through electrodes that are placed on the skin.
  • In this a video image of the heart is created with the help of sound waves.
  • CT scan
  • MRI
  • Coronary Angiogram
  • Myocardial Biopsy- A small, flexible biopsy cord is inserted into a vein in the neck or groin to collect small pieces of the heart muscle

Types of Heart Failure

  • Left-sided heart failure- It involves the accumulation of fluids in the lungs leading to shortness of breath.
  • Right-sided heart failure- It involves the accumulation of fluids in the abdomen, legs & feet leading to swelling.
  • Systolic heart failure- In this condition, the left ventricle cannot contract leading to a pumping problem.
  • Diastolic heart failure- In this condition, the left ventricle can’t relax or fill fully, leading to a filling problem.
