Background and Purpose-There is scant information available on the incidence of transient ischemic attack (TIA) in a defined population.
This study defines incidence rates of first TIA and subtypes of TIA during 1985-1989 and compares the incidence to that obtained from a 1960-1972 cohort study.
Methods-Medical records of all residents of Rochester with potential diagnosis of TIA during 1985-1989 were screened to determine whether the case met the criteria for TIA.
All available data were used to determine the vascular distribution of the TIA.
Average annual age-and sex-adjusted incidence rates were calculated for 1985-1989, and results were compared with incidence rates determined in a Rochester-based 1960-1972 cohort study.
Two hundred two cases of first TIA or amaurosis fugax occurred among Rochester residents during 1985-1989.
The age-and sex-adjusted incidence rate for any TIA was 68/100 000 population.
Incidence of amaurosis fugax was 13/100 000 ; anterior circulation (cerebral) TIA, 38/100 000 ; and vertebrobasilar distribution TIA, 14/100 000.
Rates were similar to those determined from a 1960-1972 cohort study.
Conclusions-The incidence rate of TIA is 41% that of stroke incidence.
TIA incidence in Rochester, Minn, is higher than has been previously reported for other sites throughout the world. (...)
