Why the study?
What are the preprocedural determinants of exercise-induced ST-segment depression in patients without restenosis after successful coronary angioplasty?
What are the preprocedural determinants of exercise-induced ST-segment depression in patients without restenosis after successful coronary angioplasty?
In patients without restenosis after LAD angioplasty, exercise-induced ST-segment depression is strongly associated with preprocedural regional ventricular dysfunction that has recovered by follow-up.
No takes yet. Share an insight, caveat, or question.
Preprocedural anterior hypokinesis may explain post-angioplasty exercise-test positivity without restenosis; leaves open causal mechanisms and need for prospective validation.
Beregi et al. (1994) studied this question.
