What does left ventricular hypertrophy (LVH) indicate?

Left ventricular hypertrophy (LVH) is primarily an indication of heart damage or adaptation due to excessive workload on the heart. This condition occurs when the heart's left ventricle, responsible for pumping oxygenated blood to the body, enlarges and thickens in response to factors such as high blood pressure or heart valve disease.

When there is persistent increased demand on the heart, such as from chronic hypertension or increased resistance against which the heart must pump, the muscle fibers in the left ventricle adapt by getting larger and denser. This change is not simply a sign of strength but rather a response to abnormal stress on the heart muscle, which may lead to various complications if not addressed.

Conversely, the other options do not accurately represent the implications of LVH. Suggesting that it indicates underworking or normal heart functioning overlooks the underlying pathology. Moreover, describing it as a strong heart muscle does not recognize the potential for LVH to signify deteriorating heart health and increased risk for cardiovascular events.
