Complications

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:

• Reduced 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 that increases the risk of stroke
• Insufficient supply of oxygen to the heart (ischemic heart disease)
• Stroke
• Sudden, unexpected loss of heart function, breathing and consciousness (sudden cardiac arrest)
