Risk of second @entity173 persists for years after initial XXXX .

BACKGROUND: Secondary prevention often targets @entity1 who suffer from higher rates of second @entity173 than @entity1 , especially in the early years after first @entity174 . Yet, the occurrence of second @entity173 by certain times also depends on the death rate, which is higher in @entity1 than @entity1 . We compared the risk of sustaining second @entity173 by a certain time between @entity1 and @entity1 remaining alive at that time. METHODS: We retrieved 38,383 hospitalization records of @entity1 aged 60years or older, who were discharged alive after admission for @entity173 surgery between 1990 and 2005 in British Columbia, Canada. The outcome variable was the time to a subsequent @entity173 . RESULTS: During ten years of follow-up, 2,902 (8%) @entity1 sustained a second @entity173 , and 21,428 (56%) died before sustaining a second @entity173 . The risk of second @entity173 in the surviving post- @entity174 @entity1 was higher in @entity1 than in @entity1 : 2% vs 2%, 5% vs 4%, 9% vs 7%, 15% vs 13%, and 35% vs 30% at 1, 2, 3, 5, and 10years after initial @entity130 , respectively, crude @entity15498 (95% CI: 1.13-1.39). However, the risk did not differ between @entity1 and @entity1 after adjustment, OR=1.09 (95% CI: 0.98-1.21). CONCLUSIONS: The risk of second @entity173 persists for at least ten years among @entity173 survivors, and therefore secondary prevention should continue beyond an early post- @entity174 period. @entity1 and @entity1 have similar risks of second @entity173 and both should be considered for secondary prevention.
