Abstract
BACKGROUND: <0.001 for trend for each) between 2000-2008, adjusted rates of decline varied by region (annual declines ranging from 2.9-6.1%). Widening geographic disparities, as measured by percent change of between-state variance from 2000-2008, were observed for MI incidence (37.6% increase, P=0.03) and percutaneous coronary intervention rates (31.4% increase, P=0.06). Significant declines in risk-adjusted 30-day mortality were observed in all regions, with the fastest declines observed in states with higher baseline mortality rates.ConclusionsIn a large contemporary analysis of geographic trends in MI epidemiology, the incidence of MI and associated mortality declined significantly in all US Census Divisions between 2000-2008. Although geographic disparities in MI incidence may have increased, regional differences in MI-associated mortality have narrowed.
