Drugs for the Treatment of Cardiovascular Disease
Cardiovascular system is one of the most complex organ systems. It includes blood vessels, lymphatic vessels, the heart. The following blood vessels are distinguished: arteries, arterioles, capillaries, venules, veins.
Cardiovascular diseases may affect different organs of the system. According to WHO classification the cardiovascular diseases are divided in the following groups:
- Ischemic hear disease - disease of the blood vessels, which supply the blood to the cardiac muscle
- Disease affecting vessels of the cerebrum
- Diseases affecting peripheral arteries, which supply the blood to the extremities
- Rheumatic heart disease - the disorder of the cardiac muscle and valves as a result of rheumatic attack, caused by streptococcal bacteria
- Hereditary cardiac defect - innate deformation of heart structure
- Deep vein thrombosis and pulmonary embolism - formation of blood clots in lower veins, which may move to the heart or lungs.
Heart attacks and insult to the brain are acute disorders, which develop primarily due to congestion of vessels, which prevent the blood from reaching the hear and brain. The most widespread cause of the above is formation of fat deposits on the internal walls of the blood vessels, which supply the heart and the brain with blood. Hemorrhage in the brain or blood clots may also be the cause of cerebral insult.
