Cardiovascular diseases are the scourge of our time. The most common heart disease now is coronary artery disease, which is manifested by attacks of angina pectoris, and, like many other diseases, angina pectoris is rapidly becoming “younger”. Most often, the cause of ischemia is atherosclerotic changes in the blood vessels of the heart and the stressful rhythm of life. Atherosclerosis occurs when cholesterol metabolism is disrupted. This word is heard by many, but how many people know what cholesterol is, why it rises and what to do to prevent this from happening, and if it does happen, to stop the process? Separate chapters will be devoted to cholesterol and stress, as two main factors in the development of ischemia, because it is known that the disease is easier to prevent than to treat later. In addition, the book will tell you what examinations are carried out if ischemia is suspected and why these examinations are necessary, and what drug treatment is used. Folk recipes for combating this disease, diet, therapeutic exercises and methods of providing first aid for attacks are given.
