Heart Chambers

The inside of a normal heart is divided into four chambers:
  • The right atrium
  • The left atrium
  • The right ventricle
  • The left ventricle.
Types of heart diseases that can affect the heart chambers include:


    • Diastolic dysfunction
    • Systolic dysfunction


  • Cor pulmonale (also known as pulmonary heart disease), which is an enlarged right ventricle.

Heart Muscle

The heart is a muscle about the size of a fist. Its job is to pump blood through a network of blood vessels. These vessels form a loop, which starts at the heart, goes out through your body, and then ends back at the heart again. Heart diseases that can affect the muscle itself include:
  • Cardiomyopathy, including:


    • Dilated cardiomyopathy
    • Hypertrophic cardiomyopathy
    • Restrictive cardiomyopathy


  • Myocarditis, which is an inflammation of the heart muscle.

Heart Valves

In a healthy heart, there are valves that keep blood flowing in one direction. When they open, they only allow the right amount of blood through, and then they close to keep blood from flowing backward in between beats. Types of heart diseases that can affect the heart valves (valvular heart disease) include:
