Unstable angina involves complex plaques causing platelet activation. Therapies like nitrates, beta blockers, aspirin, and heparin improve outcomes, with surgery beneficial for some patients with reduced ejection fraction.

Area of Science:

  • Cardiology
  • Vascular Medicine
  • Pharmacology

Background:

  • Unstable angina pathophysiology involves complex atherosclerotic plaques.
  • These plaques trigger platelet activation and fibrin deposition in coronary arteries.

Purpose of the Study:

  • To review current understanding of unstable angina pathophysiology.
  • To discuss the efficacy of various therapeutic strategies.

Main Methods:

  • Literature review of recent advancements in unstable angina.
  • Analysis of pharmacological and surgical treatment options.

Main Results:

  • Nitrates, beta blockers, calcium channel blockers, aspirin, and heparin demonstrate therapeutic benefits.
  • Coronary artery bypass graft surgery improves survival in specific patient groups.

  • Percutaneous transluminal coronary angioplasty is a potential alternative for select cases.

    • Conclusions:

    • Current therapies effectively manage unstable angina symptoms and reduce adverse events.
    • Surgical intervention offers survival benefits for patients with reduced ejection fraction.
    • Further trials are needed to establish the role of percutaneous transluminal coronary angioplasty.
