Exercise-induced ST-segment changes 3 months after angioplasty sometimes
may show a false-positive result, We therefore analyzed the ST changes
observed during the exercise tests performed before and 3 months after
angioplasty in 118 patients with single-vessel coronary artery disease.
Ninety-two (78%) of the 118 patients had ST changes in the same lead
before and after angioplasty whereas the remaining 26 (22%) patients
had ST changes in other leads in the postangioplasty exercise test when
compared with the preangioplasty test. Restenosis was found in 44 (48%)
of the 92 patients with ST changes in the same lead but in only 4 (15%)
of the 26 patients with ST changes in other leads. We conclude that
exercise-induced ST segment changes are not reliable markers of
restenosis 3 months after angioplasty. ST segment changes observed in
other leads after angioplasty may show a false-positive result when
compared with the preangioplasty exercise test.
