There are few published data on the incidence of fatal and non-fatal stroke in American Indians. The aims of this observational study were to determine the incidence of stroke and stroke risk factors among American Indians. This report is based on 4549 participants aged 45–74 at enrollment in the Strong Heart Study, the largest longitudinal, population-based study of cardiovascular disease and its risk factors in a diverse group of American Indians. At baseline examination in 1989–1992, 42 participants (1132/100,000, adjusted to the age and sex distribution of the U.S. adult population in 1990) had prevalent stroke. Through December 2004, 306 (6.8%) of 4507 participants without prior stroke suffered a first stroke at a mean age of 66.5 years. The age- and sex-adjusted incidence was 679/100, 000 person-years. Non-hemorrhagic cerebral infarction occurred in 86% of participants with incident strokes; 14% suffered hemorrhagic stroke. Overall age-adjusted 30-day case-fatality from first stroke was 18%, with a one-year case-fatality of 32%. Age, diastolic blood pressure, fasting glucose, HbA1C, smoking, albuminuria, hypertension, pre-hypertension and diabetes were risk factors of incident stroke. Compared to U.S. white and black populations, American Indians have a higher incidence of stroke. The case-fatality rate for first stroke is also higher in American Indians than in the U.S. white or black population in the same age range. Our findings suggest that blood pressure and glucose control and smoking avoidance may be important avenues for stroke prevention in this population.
