Area of Science:

  • Cardiology
  • Emergency Medicine

Background:

  • Unstable angina is a severe acute coronary syndrome.
  • It stems from atherosclerotic plaque rupture, platelet aggregation, thrombus formation, and coronary spasm.
  • Postinfarction angina patients are a high-risk group with increased mortality and infarct extension risk.

Purpose of the Study:

  • To outline the pathophysiology and clinical management of unstable angina.
  • To highlight the importance of early intervention in high-risk patients.

Main Methods:

  • Review of clinical presentation and pathological mechanisms.
  • Discussion of current therapeutic strategies, including medical management and revascularization.

Main Results:

  • Unstable angina requires prompt identification and management of exacerbating factors.

  • Medical therapy includes nitrates, beta-blockers, calcium channel blockers, aspirin, and heparin.
  • Thrombolytic therapy can rapidly stabilize patients.
  • Percutaneous transluminal coronary angioplasty and coronary artery bypass grafting are options for refractory or indicated cases.

    • Conclusions:

    • Effective management of unstable angina involves a multi-faceted approach.
    • Timely medical and interventional therapies are essential to reduce mortality and morbidity.
