To describe the patterns of recurrence and survival of patients following their first acute myocardial infarction (AMI).
A retrospective follow-up study based on the population of Nova Scotia and Saskatchewan from 1981-85.
The analyses were performed on patients aged 25 to 75 years (n = 2083) who had been admitted to hospital with their first AMI during 1981 from the provinces of Nova Scotia and Saskatchewan.
The rate of recurrence of AMI was 10% in men and 7% in women, regardless of age. Median time to recurrence was 13 to 15 months in men and seven months in women. After the first AMI, mortality rates were higher in women one week and one month after the initial infarction, reaching statistical significance (only in the 55- to 74-year-old age group)--P < 0.01 and P < 0.02, respectively. Five-year mortality rates were significantly higher in the older age groups (P < 0.01), but were similar in men and women.
Reinfarction occurs more quickly in women, who also appear to be at a higher risk of death during the first month, and especially during the first week, postinfarction.
描述首次急性心肌梗死（AMI）患者的复发模式和生存情况。
基于1981 - 1985年新斯科舍省和萨斯喀彻温省人群的回顾性随访研究。
对1981年期间因首次AMI入住新斯科舍省和萨斯喀彻温省医院的25至75岁患者（n = 2083）进行分析。
无论年龄大小，男性AMI复发率为10%，女性为7%。男性复发的中位时间为13至15个月，女性为7个月。首次AMI后，女性在初始梗死发生后1周和1个月时的死亡率较高，具有统计学意义（仅在55至74岁年龄组）——分别为P < 0.01和P < 0.02。老年组的五年死亡率显著更高（P < 0.01），但男性和女性相似。
女性再梗死发生得更快，且在梗死发生后的第一个月，尤其是第一周，死亡风险似乎也更高。
