Sex-based short- and long-term survival in patients following complicated myocardial infarction

Area of Science:

• Cardiology
• Clinical Research
• Sex Differences in Medicine

Background:

• Mortality after acute myocardial infarction (AMI) is higher in women than men.
• Women are typically older and have more comorbidities at the time of AMI.

Purpose of the Study:

• To investigate sex-based differences in the management and prognosis of high-risk patients post-AMI.
• To evaluate short- and long-term outcomes in women versus men following AMI.

Main Methods:

• Analysis of data from the OPTIMAAL trial, including 1575 women and 3902 men with AMI.
• Follow-up period of 2.7+/-0.9 years across seven European countries.
• Comparison of management strategies and mortality rates, adjusting for age and comorbidities.

Main Results:

• Women presented with more symptomatic heart failure, hypertension, and diabetes mellitus.
• Fewer women received thrombolytic therapy compared to men.
• While long-term mortality risk was similar after age adjustment, in-hospital mortality was significantly higher in women, persisting even after adjusting for age and comorbidities.

Conclusions:

• Age-adjusted long-term survival post-AMI is comparable between sexes in high-risk populations.
• Women experience significantly higher in-hospital mortality following AMI.
• These findings suggest a need for more rapid and appropriate management strategies for women presenting with AMI to address short-term risks.
