Left ventricular hypertrophy changes both the structure and function of the chamber:

  • The enlarged muscle loses elasticity and stiffens, preventing the chamber from filling properly and leading to increased pressure in the heart.
  • The enlarged muscle tissue compresses its own blood vessels (coronary arteries) and may restrict its own supply of blood.
  • The overworked muscle weakens.

Complications that can occur as a result of these problems include:

  • Inability of your heart to pump enough blood to your body (heart failure)
  • Abnormal heart rhythm (arrhythmia)
  • Insufficient supply of oxygen to the heart (ischemic heart disease)
  • Interruption of blood supply to the heart (heart attack)
  • Sudden, unexpected loss of heart function, breathing and consciousness (sudden cardiac arrest)
