Interventional Techniques in the Management of Unstable Angina Pectoris

Just as unstable angina may be viewed as part of a continuous clinical spectrum between stable angina and myocardial infarction, the syndrome of unstable angina comprises a spectrum of pathophysiological states. Depending on the definition used, angina may be considered unstable because of a worsening of symptoms two months previously [1], ], or it may be an acute syndrome refractory to medical therapy requiring hospitalization in a coronary care unit. Management strategies necessarily differ according to the urgency of the clinical problem. Myocardial revascularization provides excellent symptomatic relief for patients with anginal syndromes, and recently percutaneous coronary angioplasty has been used as a definitive treatment for patients with unstable angina. Success rates have been high and complication rates acceptable as summarized in the article by Drs Johnson and Ports.
