Left ventricular hypertrophy changes the structure and working of the heart. The enlarged left ventricle can:

  • Weaken
  • Stiffen and lose elasticity, preventing the chamber from filling properly and increasing pressure in the heart
  • Compress the chamber's blood vessels (coronary arteries) and restrict its supply of blood

As a result of these changes, complications of left ventricular hypertrophy include:

  • Interruption of blood supply to the heart
  • Inability of the heart to pump enough blood to your body (heart failure)
  • Abnormal heart rhythm (arrhythmia)
  • Irregular, often rapid heartbeat (atrial fibrillation) that decreases blood flow to the body
  • Insufficient supply of oxygen to the heart (ischemic heart disease)
  • Enlargement of a section of the aorta (aortic root dilation)
  • Stroke
  • Sudden, unexpected loss of heart function, breathing and consciousness (sudden cardiac arrest)
