Coronary Angioplasty in Impending and Evolving Myocardial Infarction
The clinical syndrome of unstable angina causes great concern to clinicians because of the perceived high risk of progression to myocardial infarction or death. The various options among pharmacological treatment and surgery have led to one consensus. It is now common practice to initially stabilize the acute ischemic symptoms with intensive medical treatment first and to reserve bypass surgery for those refractory to medical treatment. Since PTCA has gained acceptance as an alternative form of revascularization, patients with unstable angina pectoris, although initially not thought suitable as candidates, because of their instability, have successfully undergone this procedure [1, 2]. Now that investigator experience has grown and as significant advances have been made in catheter technology, it was considered timely to present our experience with emergency PTCA, with a steerable dilatation catheter, as an alternative to CABG.
