Unstable angina that occurs in the early postinfarction period is associated with an increased incidence of unfavorable cardiac events despite aggressive medical therapy. We examined the results of coronary angioplasty in 47 consecutive patients with postinfarction unstable angina who were referred for the procedure 12.9 ± 7 days following myocardial infarction, 14 of which were Q wave and 33 of which were non‐Q‐wave. Coronary angioplasty was performed on a total of 55 arteries with a mean predilatation stenosis of 95 ± 8%. These included 46 infarct‐related arteries and nine noninfarct arteries. Double‐vessel angioplasty was performed in eight patients. Successful coronary angioplasty (greater than 30% reduction of predilatation stenosis) was achieved in 43 patients (91%), with a mean residual stenosis of 33 ± 28%. There was one in‐hospital death, one patient required emergency bypass surgery, and two patients had early reocclusion resulting in myocardial infarctions. The 39 patients who had successful angioplasty procedures and who were discharged from the hospital without an unfavorable outcome were followed for 16.3 ± 7 months, and repeat coronary angioplasty was required in five patients from 45 to 105 days after the initial procedure. Two patients had subsequent elective bypass surgery, one had a recurrent myocardial infarction, and one patient had a noncardiac death. For selected patients with suitable coronary anatomy, coronary angioplasty appears to offer an efficacious therapeutic option for early postinfarction unstable angina.
