Recent Trends in Hospital Mortality of Acute Myocardial Infarction—the Worcester Heart Attack Study

摘要: Background: While age-related differences in patterns of care for acute myocardial infarction have been demonstrated, temporal trends clinical outcome patients different age groups not carefully examined. Methods: We analyzed data collected as part an ongoing communitywide study 5480 hospitalized with validated Worcester, Mass, during 7 selected years spanning a 15-year period (1975 through 1990). Patients were stratified into three groups: less than 65 (n=2220), 74 (n=1595), and 75 or older (n=1665). Within each group, the odds in-hospital death determined by year, adjustments demographic, clinical, hospital characteristics. Results: For years, dying phase reduced all relative to reference year (1975), reaching their lowest level 1990 (adjusted ratio [OR], 0.16; 95% confidence interval [CI], 0.06 0.48). aged declined among 1978 OR, 0.71; CI, 0.39 1.29) 1981 0.36; 0.19 0.66) but remained essentially unchanged subsequent 1990. older, 1984 0.42; 0.25 0.72) increased over following years: 1986, 1988, Conclusions: risk has recently age, improvements realized groups. Current management require reexamination. (Arch Intern Med. 1994;154:2202-2208)
