Accidental Cerebrovascular in Villages Situated at Great Altitudes. Revisions and Analysis of the Risk Factors

Abstract:

Despite our understanding about cerebrovascular accident, also known as stroke, its risk factors, treatment and prevention, it remains the leading cause of death of both men and women worldwide. Several risk factors have been associated with higher incidence of stroke such as systolic or diastolic hypertension, diabetes, hypercholesterolemia, cigarette smoking or obesity. Other such as cocaine abuse, heavy alcohol consumption, AIDS, Vitamin D and protein C deficiency are also important non traditional risk factors, associated with increased prevalence of stroke. Nevertheless, high altitude exposure and potential impact of hypoxia as a stroke risk factor–in people living or visiting high altitude environments–has not been clearly established yet. This review will analyze the available evidence concerning about the association of risk factors with higher prevalence of stroke during acute or chronic high altitude exposure, either in high altitude dwellers or new sojourners.
