Implication

Normalized post-PTCA exercise ECG identifies low restenosis risk; leaves open whether routine angiography can be safely omitted.

Key Points

Determine whether normal exercise electrocardiography results can identify patients who do not require routine repeat coronary angiography following successful angioplasty.
Cohort evaluation of 398 patients undergoing comparable workload exercise ECGs before, immediately after, and within 6 months post-angioplasty.
Tracked exercise-induced ST-segment depression and anginal symptoms to assess indications for repeat coronary angiography and repeat angioplasty.
In patients with normalized exercise ECGs (n = 166), restenosis occurred in 16.3% and repeat angioplasty was indicated in 6.6%, decreasing to 3.2% if patients also remained free of angina.
Renewed ST-segment depression (n = 77) was associated with a 67.5% restenosis rate and a 52.0% rate of indication for repeat angioplasty.
Patients with unchanged exercise tests across all time points (n = 155) had a restenosis rate of 25.8%, with repeat angioplasty recommended in 14.2%.

Structured PICO

Does exercise ECG predict the occurrence of restenosis and the need for repeat PTCA in patients after successful PTCA?

Population

398 patients who underwent successful transluminal coronary angioplasty (PTCA) and had exercise tests of comparable workload before, immediately after, and within 6 months after PTCA

Intervention

Exercise ECG testing before, immediately after, and within 6 months after PTCA

Outcome

Occurrence of restenosis and indication for repeat PTCAsurrogate

A normalized exercise ECG combined with the absence of angina after successful PTCA identifies patients at very low risk for needing repeat intervention, potentially avoiding routine angiographic restudy.
