Modern acute myocardial infarction (MI) management has significantly reduced mortality through antithrombotic therapy and timely reperfusion. Challenges remain in applying evidence to all patients and addressing global cardiovascular disease trends.

Area of Science:

  • Cardiology
  • Clinical Medicine
  • Evidence-Based Practice

Background:

  • Acute myocardial infarction (MI) management has evolved over 30 years, significantly reducing mortality and morbidity.
  • Success relies on integrating antithrombotic therapy with timely reperfusion strategies (PCI or fibrinolysis for STEMI; invasive care for NSTEMI).
  • Risk stratification and optimized care systems are crucial for effective MI management.

Purpose of the Study:

  • To discuss the pathophysiology, diagnosis, risk stratification, and management of myocardial infarction.
  • To highlight the evolution of MI care based on clinical evidence.
  • To address challenges in translating evidence to diverse patient populations and global health trends.

Main Methods:

  • Review of clinical evidence from studies over the past three decades.

  • Analysis of diagnostic advancements, including troponin assays and the universal definition of MI.
  • Discussion of therapeutic strategies, including antithrombotic therapy, reperfusion, and revascularization.
  • Main Results:

    • Substantial reduction in mortality and morbidity associated with acute MI.
    • Improved understanding of MI pathophysiology through troponin assays and universal classification.
    • Emerging awareness of adverse events like bleeding and disparities in care.

    Conclusions:

    • Effective MI management integrates antithrombotic therapy with timely reperfusion and risk stratification.
    • Challenges include equitable evidence translation for underrepresented groups (elderly, renal failure) and global health shifts.
    • Future demands on healthcare systems will increase due to diabetes, obesity, and the rise of cardiovascular disease in developing nations.
