According to the statistics of the World Health Organization, the mortality from cardiovascular diseases is several times higher than the total mortality from all other significant causes: pneumonia, cancer, liver cirrhosis, diabetes mellitus and chronic lung diseases
Diseases of the heart are divided into:
- hypertonic disease
ischemic heart disease
- congenital heart diseases
- rheumatic heart diseases
- Syphilitic heart diseases
There are also some heart diseases that do not fall into one of the above groups:
- Atrial flutter (sufficiently accelerated atrial contraction, beyond which the ventricles of the heart do not have time)
- thrombosis of the coronary vessels (usually occurs as a result of atherosclerosis)
- atrial fibrillation (strongly accelerated contraction of some muscle fibers of the atria, while full reduction does not occur)
- acute dilatation of the heart (occurs as a result of an overload with a large volume of blood of a weak cardiac muscle, while the heart greatly increases, is filled with blood and stretched)
- Myocardial infarction (as a consequence of insufficient supply of blood, necrosis of a certain area of the heart muscle occurs)
- heart failure is the end result of any heart disease
Most of the cardiovascular disease develops as a result of an incorrect lifestyle, which leads to a gradual clogging of the arteries. As a result of the accumulation of cholesterol, fats and triglyceride, the walls of the arteries become denser, resulting in atherosclerosis, cardiac asthma, various myocarditis, stenocardia, cardiosclerosis and other cardiovascular diseases.
The heart is perhaps the most reliable and durable organ that can work even in the event of brain death. Therefore, if it is well nourished with oxygen and necessary nutrients, and not poisoned with alcohol and nicotine, it can function smoothly up to one hundred and fifty years.
