[Undesirable outcome of percutaneous transluminal coronary angioplasty including irreversible damage and re-stenosis of dilated lesions].
To clarify the prognostic implications due to the limitations of coronary angioplasty, 564 newly-dilated lesions were analyzed for the prevalence of irreversible damage (sudden deaths, myocardial infarction, re-stenotic lesions and occlusion unsuitable for or unsuccessful following repeated angioplasty) and re-stenosis after re-dilatation. Re-stenosis occurred in 170 of the 564 newly-dilated lesions, and in 36 of the 135 re-dilated lesions. After repeated angioplasty, up to three times, 449 lesions (89.9%) were eventually patent angiographically, while irreversible damage was observed in 21 lesions. Re-stenosis after re-dilatation was observed more often in variant angina and in lesions exceeding 15 mm in length. Irreversible damage occurred more often in elderly patients and in patients with lesions of the right coronary artery.
