arteriosklerose

Arteriosklerose, commonly known as hardening of the arteries, is a medical condition characterized by the thickening and stiffening of artery walls. This process occurs due to the buildup of plaque, a deposit of cholesterol, fat, calcium, and other substances, on the inner lining of the arteries. As plaque accumulates, it narrows the arteries, restricting blood flow. This narrowing can affect arteries throughout the body, including those supplying the heart, brain, and limbs.

The exact causes of arteriosclerosis are not fully understood, but several risk factors are strongly associated with its development. These include high blood pressure, high cholesterol levels, smoking, diabetes, obesity, a sedentary lifestyle, and a family history of heart disease. Age is also a significant factor, as the risk of developing arteriosclerosis increases with advancing years.

The consequences of arteriosclerosis depend on which arteries are affected. If the coronary arteries, which supply blood to the heart, become narrowed, it can lead to angina (chest pain) or a heart attack. Blockages in the arteries supplying the brain can cause a stroke. Narrowing of the arteries in the legs can result in peripheral artery disease, causing pain and cramping during physical activity.

Diagnosis typically involves a review of medical history, physical examination, and various diagnostic tests such as blood tests to check cholesterol and blood sugar levels, blood pressure measurement, electrocardiogram (ECG), and imaging studies like ultrasound or angiography. Treatment focuses on managing risk factors and may include lifestyle modifications, medications to lower blood pressure and cholesterol, and in some cases, surgical procedures to open blocked arteries.
