The major pumping chamber of the heart is the left ventricle. This heart chamber pumps oxygenated blood into the aorta, the large blood vessel that delivers blood to the body's tissues. If the left ventricle has to work too hard, its muscle enlarges and becomes thick. This is called left ventricular hypertrophy (LVH). Because of the increased thickness, blood supply to the muscle itself may become inadequate. This can lead to cardiac ischemia, myocardial infarction or heart failure.

Heart failure develops over time as the heart's pumping action grows weaker. The condition can affect the right side of the heart only, or it can affect both sides of the heart.
