It is an insidious disease because it does not give any noticeable symptoms at the initial stage. It brings with it limitations which hinder everyday functioning, which translates into a decrease in the quality of life of patients affected by this disease. This is why preventive action and preventing the development of cardiovascular diseases is so important. The aim of the study.
