The XXXX registry: results of a five-year hospital-based study.

The advent and wide application of new technology, especially noninvasive techniques, has enabled physicians to more completely investigate and clarify the etiopathogenic mechanisms of @entity64 . Such data have not been available until recently for Southeastern Europe. In addition, during the last decades, strategies for the modification of risk factors and primary prevention may have changed the prevalence of each subgroup of @entity64 as well. We investigated 1, 042 consecutive @entity1 who had first @entity64 , during a period of 5 years (from June 1992 to May 1997) and classified them prospectively based on etiopathogenic mechanisms. @entity1 with transient @entity63 attacks and @entity510 were excluded. There were 613 male and 429 female @entity1 , with a mean age of 70.2 +/- 11.9 years. Forty-six percent of the @entity1 arrived within 3 h from @entity64 onset. The probable mechanisms were: large-artery @entity731 , 156 (15%); lacunes, 177 (17%); cardioembolic, 335 (32.1%); @entity1188 of unknown cause, 182 (17.5%); miscellaneous causes, 35 (3.3%), and @entity1779 ( @entity1779 ), 157 (15.1%). In the cardioembolic group, nonvalvular @entity955 (NVAF) was the probable cause in 225 @entity1 , especially in @entity1 older than 75 years (65%). The overall hospital mortality was 15.2% (from 0.6% for @entity64 to 34% for @entity1779 ). In our population, cardioembolism is the most frequent subtype of @entity64 . NVAF is the most likely source, especially in older @entity1 .
