Epidemiology of Stroke
Stroke may become the most usual cause of death throughout the world. It is the second high cause of death in the western countries, ranking before cancer and after heart disease, and leading to 10% of death in the world. According to the observed geographic dispatities, southeastern United States is included in a “stroke belt”, while the causes of the disparities have not been explained.
The etiology of stroke varies by age, and incidence increases exponentially from 30-year of age. Senile age is one of the most important stroke risk factors. People with the age of 45 and older suffer storke often, which 95% of storkes is around this range, while 2/3 of strokes occur in those over 65. However, stroke can occur at any age, fetuses included.
Family members may share a lifestyle that contributes to stroke, or have a genetic tendency for stroke. Higher levels of Von Willebrand factor are more ordinary among people who have had ischemic stroke for the first time. The results of the study showed that the only important genetic factor was the person’s blood type. Having had a stroke in the past increases one’s risk of future strokes greatly.
Men are 25% more likely to have strokes occurred than women, yet 60% of deaths from stroke are women. This is because that women live much longer, they are older on average of the stroke age and thus more often killed. Some risk factors for stroke only present among women. Primary of these are pregnancy, childbirth, menopause and the related treatment.
