Diseases of heart and vessels

Complex and harmonious work of the staff of the circulation and respiration of the human body is another obvious evidence that between man and nature even in our civilized world there is a close relationship.
This relationship long before we were born. During the life of the fetus, the fetus receives maternal blood rich in oxygen, which in light of the fruit enters the left heart, and through the blood vessels and capillary system is delivered to all organs, tissues and cells, providing continuous metabolic process that underlie life. As a result of this ongoing process in the internal environment of the fetus accumulate carbon dioxide and metabolites, which are transported to the lungs, kidneys, skin and go through the umbilical cord in the venous system of the mother's blood.
The relationship between the fetus and the mother set via the placenta (infant beds), including arterial and venous vessels that supply the fruit of plastic and energy materials.
At the first breath of a child at the time of his birth received in the light air provides the body with oxygen; carbon dioxide, which accumulate, displayed to the outside world. The mechanism of this exchange complex. To some extent it is based on physical laws perfusion gases through the cell membrane and is carried out with the help of erythrocytes (red blood cells) in the blood. These cells contain hemoglobin (dye), which is at the junction of the finest pulmonary alveoli captures oxygen and creates an unstable connection, forming oxyhemoglobin. Proceeding through the capillary network in the intercellular space, the blood contains red blood cells with oxyhemoglobin, it oxygen, which are involved in the metabolic processes of the cell. The accumulated as a result of these processes in the cell carbon dioxide is connected after the bestowal of oxygen from hemoglobin red blood cells and creates new legkobetonnyh connection - carboxyhemoglobin. These red blood cells, getting through the pulmonary artery to the lungs by the same laws for gases, give carbon dioxide and again saturated with oxygen.
This uninterrupted exchange of gases indicates a permanent connection between the external and internal environment of the body. Once this exchange is terminated or even temporarily reduced sharply decreases the redox potential of the organism and for a complete cessation of exchange of these gases develops severe hypoxia of the brain, heart, lungs, liver, kidneys and, if it persists, ultimately leads to death.
The heart and its vessels, which are constantly circulating blood, constitute a single system, providing the link between the organism and the environment not only by gas exchange, but with the help of the mechanisms underlying revenues from the gastrointestinal tract main energy (carbohydrates, and fats) and plastic (proteins) materials, as well as microelements and vitamins, mineral salts and water, which in the result of the smooth blood circulation provide vital activity of an organism. When you encounter various circulatory obstacles in the body due to diseases of the cardiovascular system or blood system or liver disease or portal system for transport or any other causes significantly reduced activity of the organism and restore it is very difficult.
Doubtless interest is a complex transformation in the body, lying in the basis of development of various diseases of heart and vessels, methods of their prevention and treatment.
How often now meet these diseases? How can they be prevented? If 100 years ago coronary system attack occurred very rarely, but now, in the age of scientific and technological progress, not only are they widely accepted, but more than 50% of cases end in death. Currently in the world of high mortality and premature disability in cardiovascular diseases. So, according to the who, in the USA from these diseases annually dies 600 thousand people. Economic losses are estimated by many billions of dollars a year. In the USSR 10-12 years ago, during one year from myocardial infarction died 100 thousand people. There is virtually no age group, especially the male population, wherever it was noted the increase in mortality from coronary heart disease.
Epidemiological studies in the USSR showed that coronary heart disease in General was detected in 21,7% of cases, and from the total number of patients mass screenings at 40.3% of the disease was installed for the first time, including angina (attacks of angina pectoris due to physical force) occurred in 44%, myocardial infarction - 23.4%, and painless form of myocardial infarction - half of the patients. Within 5 years of observation frequency of coronary heart disease per 1000 persons in Finland amounted to 120, USA - 80, Japan 20 cases.
The above statistics show that the frequency of diseases of the cardiovascular system in different countries varies and is determined by the degree of urbanization and industrial development of these countries, climate-geographical peculiarities of each region and the nature of power, professional activities and others
