[Precordial S-T stress mapping in the evaluation of the effects of percutaneous transluminal coronary angioplasty].
The morphological impact of percutaneous transluminal angioplasty (PTCA) on the treated artery is closely checked by coronary arteriography. Indirect non-invasive evaluations are made possible by electrocardiography, isotope methods and echocardiography which are the commonest visualization methods. The authors used a precordial S-T load map. After complete revascularization following PTCA there was a significant drop of the sum of S-T depressions and in some members of the group it reached normal values. The S-T load map is a suitable non-invasive procedure for monitoring the effect of PTCA.
