title: Comparison of hospital versus out of hospital coronary death rates in women and men.
abstract: Young women hospitalized with acute myocardial infarction (MI) have greater in-hospital mortality than young men. However, the reasons for this difference have not been well characterized. We analyzed the data from 423,067 patients (247,701 men and 175,366 women) who were discharged with the diagnosis of MI from nonfederal hospitals in New Jersey and 355,569 coronary heart disease (CHD) deaths in New Jersey from 1990 to 2004 in 4 age strata: 35 to 54, 55 to 64, 65 to 74 and > or =75 years. Of the patients hospitalized for MI, young (35 to 54 years) women had greater in-hospital mortality than young men (5.2% vs 2.5%, adjusted odds ratio 1.64, 95% confidence interval 1.48 to 1.81, p <0.0001). However, in a community-wide analysis, when the total out-of-hospital CHD deaths in New Jersey were examined, young women had a lower out-of-hospital death rate than young men (11 vs 55/100,000). Statewide, young women were 4 times less likely to be hospitalized for MI (78 vs 297/100,000, relative risk 0.26), but they were only 1/2 as likely to die from MI in the hospital (7 vs 17/100,000, relative risk 0.41). Thus, women had a greater odds ratio for in-hospital mortality but a lower odds ratio for out-of-hospital CHD death than men. In conclusion, the greater in-hospital mortality of young women hospitalized for MI compared to young men could be explained in part by the finding that young men were more likely to have out-of-hospital CHD death.
