Presenting characteristics, treatment, and clinical outcome data were obtained by chart review. At time of hospitalization, 7353 (6.4%) women reported current use of HRT, defined as use of estrogen, progestin, or estrogen\/progestin for reasons other than contraception. Unadjusted mortality was 7.4% in users of HRT and 16.2% in nonusers (odds ratio 0.41, 95% confidence interval 0.36 to 0.43). After adjustments were made for prior medical history, clinical characteristics, treatments received in-hospital, and likelihood of receiving HRT, HRT remained associated with an improved rate of survival (odds ratio 0.65, 95% confidence interval 0.59 to 0.72). Significant association of HRT with decreased mortality after myocardial infarction was observed in all age strata.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>\n                <jats:bold>\n                  <jats:italic>Conclusions<\/jats:italic>\n                <\/jats:bold>\n              <\/jats:italic>\n            <\/jats:bold>\n            Postmenopausal HRT appears to be associated with reduced mortality after myocardial infarction.
