Predisposition to stroke is determined by our genes, scientists believe. Most frequently an ischemic stroke develops when the tissue dies due to insufficient blood flow in it. Even a temporary lack of blood to part of the brain leads to necrosis, tells NDTV.
Scientists investigated the composition of the genomes of thousands of patients with a previous stroke and revealed a number of regularities. The data obtained the researchers compared with the control group.
One of the found genes, scientists believe, is directly related to the stroke. The presence of variation leads to premature atherosclerosis of large vessels, which is one of the main factors of development of ischemic stroke. If doctors learn how to influence gene, occurrence of diseases of the cardiovascular system will decrease significantly.
