It is sad that myocardial infarction often affects middle-aged and even young people who are in the prime of physical and creative strength. One of the reasons is insufficient medical literacy of the population, ignorance about the main early manifestations of myocardial infarction, angina pectoris, atherosclerosis, hypertension, ignorance about the prevention of these diseases. But prevention must begin precisely when a person feels good, considers himself healthy, i.e. from a young age.
