[Arteriosclerosis--selected aspects]. 
The article summarizes the current knowledge concerning the diagnosis of atherosclerosis and therapeutic objectives.  Atherosclerosis is one of the most common medical problems.  It affects adults as well as children.  It leads to clinically overt cardiovascular diseases (CVD), which are the cause of premature deaths.  During its course, the formation of atherosclerotic plaque takes place, along with local inflammations artery walls.  Gradually growing plaque does not cause clinical symptoms until the stenosis does not exceed 70-80% of the coronary vessel diameter, causing a marked reduction in blood flow to the heart muscle.  The prevention of atherosclerosis and its complications requires an individual assessment of cardiovascular risk.  In people without CVD symptoms, it is recommended to use SCORE risk card for Polish population, assessing the 10-year risk of cardiac death.  A key element in combating atherosclerosis is to eliminate its risk factors by both implementing pro-health policies, as well as working with individual patients.  An important objective is the proper control of blood pressure.  It should not exceed 140/90 mmHg.  A very important role is played by correct approach to patients with moderate or unusual cardiovascular risk.  Despite knowing many facts about the mechanisms of atherosclerosis and its treatment, many issues still remain to be clarified.  Finding methods to influence ongoing immune processes within arteries is of particular interest, which will soon make way to new therapeutic possibilities.
