[Mortality of cerebral infarction with auricular fibrillation. Results of a population study].
To evaluate the relationship between atrial fibrillation (AF) and mortality of the cerebral infarction, we have studied in a population survey, 540 cerebral infarctions, whose 162 were with AF (30%) and 378 without AF (70%). The group with AF differs significantly from that without AF, by the higher frequency of women (62% versus 35%), older subjects (75.4 +/- 10.2 years old versus 69.1 +/- 9.7 years old), a severe loss of consciousness, a more frequent subcortical infarction on CT-Scan. During a period of 24 months, 139 patients died, 64 among the 162 patients with AF (40%), 75 among the 378 patients without AF (20%). Rates of death are different in the 2 groups with, in the group with AF, at 1, 6, 18 and 24 months a rate of 20, 24, 37 and 40 percent. To the opposite, in the group without AF, the rates are 8, 12, 16 and 20 percent. The authors try to research the factors that may explain the mortality linked to AF, and they insist on the necessity to look for AF on admission for a stroke, to identify a subgroup of stroke patients with a high risk of death.
