Fatty streak, in medical terminology, refers to the earliest stage of atherosclerosis, which is the accumulation of fatty plaques within the arteries. Atherosclerosis is a chronic condition characterized by the progressive narrowing and hardening of the arteries, primarily caused by the buildup of cholesterol, fats, cellular waste, and calcium on the arterial walls.
The fatty streak represents the initial visible sign of this process, occurring during childhood or adolescence. It is characterized by the accumulation of foam cells, which are macrophages filled with low-density lipoprotein (LDL) cholesterol, a type of harmful cholesterol. The foam cells migrate and adhere to the inner lining of the arteries, causing the formation of yellowish streak-like lesions. These fatty streaks are typically found in the medium and large arteries, such as the aorta and coronary arteries.
While fatty streaks themselves do not cause significant obstruction or damage to the arteries, they are considered the first step in the development of atherosclerosis. Over time, the fatty streaks can progress to more advanced stages, leading to the formation of atherosclerotic plaques that can obstruct blood flow, increase the risk of blood clots, and contribute to various cardiovascular diseases, such as heart attacks, strokes, and peripheral artery disease.
Therefore, identifying and managing fatty streaks early on is crucial for preventing the progression of atherosclerosis and reducing the associated health risks. This involves adopting a healthy lifestyle, including regular physical activity, a balanced diet, and avoiding smoking, as well as medication and medical interventions as necessary.
The etymology of the term "fatty streak" can be understood by examining the origins of each individual word:
