Life expectancy and long-term survival of patients after myocardial infarction

In order to study the life expectancy and survival of patients who have suffered a myocardial infarction (MI), depending on the gender and age at which the first MI occurred, a retrospective analytical study was conducted, which included data on 907 patients who had MI. Mortality data is obtained from the medical information system of the Omsk region. The end point was "death from all causes" as of 05.10.2024. The life expectancy and long-term survival of patients who underwent MI were evaluated, depending on the gender and age at which the patient underwent the first MI. Results. The average life expectancy of patients was 68.3 years, while 88% of patients lived to the age of 60, 60% to the age of 70, and 32% to the age of 80. Women suffer their first MI at the age of 6.6 years older than men. For patients with MI under the age of 50, the median survival after MI was 20 years, while less than 25% lived to the age of 70, their 5-year survival was 93%, 10-year survival was 78%, 15-year survival was 63%, 20-year survival was 48%, 30-year survival was 31%. For patients with MI aged 50–59 years, the median survival after MI was 16.5 years, while 50% lived to the age of 70, 13% to the age of 80, their 5-year survival rate was 87%, 10-year – 70%, 15-year – 53%, 20-year – 33%, 30-year – 12%. For patients with MI aged 60 years and older, the median survival after MI was 9 years, while 82% lived to the age of 70, 50% to the age of 80, their 5-year survival was 66%, 10-year – 44%, 15-year – 29%, 20-year – 19%, 30-year – less than 10%. Conclusion. The survival rate of patients after MI depends on the age at which the patient underwent the first MI in his life.
