What is left ventricular hypertrophy? The pumps blood out of the heart through to the body. The right ventricle pumps blood to the lungs, picking up oxygen before returning to the heart to be pumped out from the left ventricle. When a condition causes the heart to work harder to supply the body with oxygenated blood, the left ventricle walls can become thicker — similar to how other muscles can become bigger from lifting weights or other exercises. This extra work results in LVH. Less commonly, LVH results from the space within the left ventricle expanding due to an abnormal increase in blood volume traveling through the heart. Having LVH can lead to life threatening complications, including heart failure and stroke, if it’s not treated effectively. (责任编辑：) |
