Background Exercise-induced ST-segment changes 3 months after
angioplasty may sometimes show a false-positive result.
Methods 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.
Results 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 test when
compared with the preangioplasty exercise test. Restenosis was found in
44 (48%) of the 92 patients with ST changes in the same lead but in
only four (15%) of the 26 patients with ST changes in other leads.
Conclusions Exercise-induced ST-segment changes are not reliable markers
of restenosis 3 months after angioplasty. ST-segment changes observed in
other leads after angioplasty compared with the preangioplasty exercise
test may show a false-positive result.
