By Mayo Clinic staffLeft 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)
