OBJECTIVE: To evaluate gender-specific and age-specific differences in the occurrence of unstable @entity951 (UAP) caused admissions. DESIGN: Population-based retrospective registry study in Finland. @entity1 : All consecutive @entity1 aged >= 30   years hospitalised with a primary diagnosis of UAP in 22 hospitals with a coronary catheterisation laboratory during 5/2000-10/2009. PRIMARY OUTCOME MEASURES: Gender-specific and age-specific differences and trends in occurrence of UAP admissions. RESULTS: The study period included 27   282 admissions caused primarily by UAP. Of these, 61.9% occurred to @entity1 and 38.1% to @entity1 with age-adjusted relative risk (RR) of 1.85 (CI 1.61 to 2.14) for the male gender (p<0.0001). The standardised incidence rate of UAP during the whole study was 92.8 (CI 91.8 to 93.9)/100   000 @entity1 -years. The incidence rate increased gradually from 1.3 in the population aged 30-34   years to 268.0/100   000 in the population aged 75-84   years. @entity1 had a 2.4-fold risk for UAP admission compared with @entity1 in the general population (incidence rate ratio 2.39; CI 2.24 to 2.56; p<0.0001). Gender difference was present in all age groups. UAP caused 22.4% of @entity1187 admissions and 4.7% of all cardiovascular admissions. UAP was more likely to be the cause of cardiovascular admission in male @entity1 (RR=1.25; CI 1.21 to 1.30, p<0.0001 compared with female @entity1 ), but there was no gender difference in @entity1187 admissions. The incidence rate of UAP hospitalisations in the general population declined by an estimated 8% per study-year (p<0.0001). Declining incidence was evident regardless of gender and age. CONCLUSIONS: @entity1 have a 2.4-fold overall RR for UAP admission compared to @entity1 in the general population. Admissions due to UAP have a declining incidence trend across the adult Finnish population.
