Unstable angina involves complex cardiac conditions. Identifying the specific cause, such as plaque disruption or extracardiac factors, is crucial for effective treatment and prognosis in patients with coronary artery disease.

Area of Science:

  • Cardiology
  • Internal Medicine

Background:

  • Unstable angina describes a complex set of cardiac conditions with varied causes and outcomes.
  • Understanding the underlying mechanisms of acute myocardial ischemia is vital for patient prognosis and treatment decisions.

Purpose of the Study:

  • To outline the diverse pathogenetic mechanisms contributing to unstable angina.
  • To emphasize the importance of identifying specific mechanisms for tailoring patient therapy.

Main Methods:

  • Review of established knowledge on the pathogenesis of acute myocardial ischemia.
  • Categorization of potential causes including extracardiac factors, plaque disruption, and atherosclerotic progression.

Main Results:

  • Identified key mechanisms: extracardiac factors, plaque disruption (thrombosis, dissection, constriction), and plaque healing.

  • Highlighted that not all mechanisms may be identifiable in every case.

    • Conclusions:

    • Accurate diagnosis of the specific pathogenetic mechanism is essential for selecting appropriate and individualized therapy for unstable angina.
    • Clinical assessment should focus on determining the cause to guide treatment strategies effectively.
