Percutaneous transluminal coronary angioplasty in silent ischemia.
The short- and long-term outcome of percutaneous transluminal coronary angioplasty were analyzed in 34 patients who had documented coronary artery disease without symptoms. Of the 34 patients, 33 had abnormal stress tests before angioplasty. Angioplasty was successful in 31 patients (91%). Follow-up was 100% for a mean period of 36 +/- 15 months. Follow-up exercise test was normal or improved in 29 of the 31 patients who had successful angioplasty. Follow-up catheterization was performed in 24 of the 31 patients (77%). Restenosis of the previously dilated segment was found in seven patients. Actuarial cardiac survival at 3 years was 100%. Freedom from myocardial infarction, bypass surgery, angioplasty for a new lesion, and death was 87%. We conclude that although the most effective treatment for silent ischemia remains to be determined, our data suggest that coronary angioplasty is a therapeutic option in these patients.
