Atherosclerosis is a chronic disease of the blood vessels in which cholesterol, lipids, and other substances gradually accumulate within the arterial walls, forming atherosclerotic plaques. As the disease progresses, the lumen of the vessels can narrow, limiting normal blood flow and increasing the risk of serious cardiovascular complications.
The main causes of atherosclerosis
The development of atherosclerosisis associated with a combination of factors. Among the most common causes are elevated blood cholesterol, high blood pressure, smoking, insufficient physical activity, and a diet high in saturated fat.
Age also plays a role, as arterial walls undergo structural changes over time. Additional risk factors include excess body weight, glucose metabolism disorders, and a family history.
How the disease develops:
In the early stages, damage to the inner lining of the artery promotes lipid accumulation. Gradually, a plaque composed of fatty deposits, inflammatory cells, and connective tissue forms in the vascular wall.
As the plaque grows, the artery's lumen can become narrower. If the surface of an unstable plaque is damaged or ruptured, the body can form a thrombus. This can dramatically reduce or completely block blood flow.
Symptoms of atherosclerosis:
In its early stages, atherosclerosis often proceeds without noticeable symptoms. Clinical manifestations depend on which vessels are affected.
Coronary artery disease can cause chest pain or discomfort, shortness of breath, and decreased exercise tolerance. Cerebral atherosclerosis can be associated with speech, vision, and coordination problems, as well as other neurological symptoms.
If the arteries of the lower extremities are affected, pain in the legs while walking, weakness, or coldness in the extremities may occur. In some cases, the condition is only discovered after a medical examination.
To assess
the cardiovascular system, a doctor may consider a medical history, risk factors, and physical examination results. Depending on the situation, blood tests to determine a lipid profile, blood pressure measurements, electrocardiography, vascular ultrasound, and imaging techniques may be used.
The choice of diagnostic procedures depends on the symptoms and the suspected location of the vascular lesion.
Prevention:
Prevention of atherosclerosis is largely associated with controlling modifiable risk factors. A balanced diet, regular physical activity, quitting smoking, and maintaining a healthy weight can help reduce cardiovascular risk.
It's also important to monitor blood pressure, cholesterol, and blood glucose levels. People at increased risk should undergo regular medical examinations and follow their doctor's recommendations.
Modern treatment approaches
Treatment tactics depend on the severity of the disease, the location of vascular lesions, and individual risk factors. A doctor may recommend lifestyle changes and drug therapy to control cholesterol, blood pressure, or other conditions that increase cardiovascular risk.
In cases of severe arterial narrowing, interventional or surgical methods of restoring blood flow may be considered in certain clinical situations.
