What condition results from a chronic lack of oxygen in tissues?

The condition that arises from a chronic lack of oxygen in tissues is hypoxia. Hypoxia occurs when there is insufficient oxygen available to the cells for their metabolic needs, thereby impairing cellular function and leading to damage if the deficiency continues over time. This can stem from various causes, such as inadequate blood flow, respiratory problems, or other factors that reduce oxygen supply to the tissues.

In contrast, cardiomyopathy refers to diseases of the heart muscle, heart failure describes the heart's inability to pump effectively, and an aneurysm involves the abnormal swelling of a blood vessel wall. While these conditions might be associated with or contribute to hypoxia, they are not directly the result of chronic oxygen deficiency in tissues. Hypoxia specifically focuses on the oxygen supply issue, making it the correct term for the given scenario.
