Stroke in rural Ecuador: a three-phase, door-to-door survey

The authors carried out a three-phase door-to-door survey in Atahualpa, Ecuador to assess epidemiologic and pathogenetic mechanisms of stroke. They found 10 stroke patients among 1,568 individuals aged > or =15 years (crude prevalence, 638 per 100,000). There was only one incident case (incidence, 64 per 100,000). Six of the 10 patients had hypertensive arteriolopathy (five with ischemic and one with hemorrhagic stroke). Additional work is needed to increase knowledge on stroke in developing countries.
