Aterosklerose

Atherosclerosis is a medical condition characterized by the gradual buildup of plaque within the arteries. Plaque is composed of cholesterol, fat, calcium, and other substances found in the blood. This buildup narrows the arteries, restricting blood flow to vital organs like the heart and brain. Over time, this narrowing can lead to serious health problems.

The exact cause of atherosclerosis is not fully understood, but several risk factors are known to contribute to its development. These include high cholesterol levels, high blood pressure, smoking, diabetes, obesity, and a lack of physical activity. Genetics and age also play a role.

Symptoms of atherosclerosis vary depending on the affected artery and the severity of the blockage. If it affects the arteries supplying the heart, it can cause chest pain (angina) or a heart attack. Blockages in the arteries leading to the brain can result in a stroke. Atherosclerosis in the legs can cause leg pain during exercise, known as claudication.

Diagnosis typically involves a physical examination, review of medical history, and diagnostic tests such as blood tests, electrocardiograms (ECG), and imaging studies like angiography.

Treatment aims to slow the progression of the disease, manage risk factors, and prevent complications. This often involves lifestyle changes such as a healthy diet, regular exercise, and smoking cessation. Medications may be prescribed to lower cholesterol, blood pressure, and prevent blood clots. In some cases, surgical procedures like angioplasty or bypass surgery may be necessary to restore blood flow.
