Gender differences in acute XXXX , twenty-five years registration.

@entity1 @entity583 @entity580 @entity13675
BACKGROUND/OBJECTIVES: The French-speaking Community of Belgium has set up a register of @entity13675 (1983-2007). The aim consists in analyzing the evolution of fatal and non-fatal acute coronary events rates as well as the 28 days case fatality on a 25-year period and examine sex differences in lethality. METHODS: This register assures a standardized procedure according to the MONICA criteria. For each period, we present attack rates and trends analysis. @entity580 takes again in- @entity1 and community lethality is calculated starting from all the cases. RESULTS: The total attack rate is rather stable between 1983 and 2007 for @entity1 (from 12 to 19 per 10,000 residents). For @entity1 , there is a distinct decline of the total attack rate since 1991 till 1993 (63 to 43 per 10,000 residents). We systematically observe a reduction in risk between @entity1 and @entity1 according to the age. For each 5-year period, this risk decreases significantly with age and this difference is strongest during the periods 1993-1997 and 1998-2002. The analysis shows also a significant decline in lethality between the 1983-1987 and 1993-1997 periods. Among @entity1 , lethality is systematically higher than in @entity1 in spite of the presence or the absence of antecedents of @entity583 . CONCLUSIONS: Favourable evolutions in the attack rates of acute coronary events in the study population appear clearly on the 25-year period of observation. The whole lethality rates decreased during the first 15 years of the register; after that, it stabilized.
