Aim: To estimate changes of ECG-12 in patients with STEMI/Unstable angina after facilitated or primary PCI LAD.

Materials and methods: 26 patients with STEMI and 2 patients with unstable angina survived facilitated or primamry PCI (with or without stenting), were devided into 2 groups according to whether tromolisis was perforemed before PCI: first group - 14 patients (13 patients with STEMI and 1 patient with unstable angina) survived facilitated PCI; second group - 14 patients (13 paients with STEMI and 1 patient with unstable angina) survived primary PCI. ECG-12 was analised before PCI (during 1-6 hours after onset of anginal (chest) pain) and 3 hours later after PCI. We analised ECG-12: decrease of ST-segment elevation, algebraic sum of R waves (excluding R wave in avR lead) and number of leads with pathologic Q wave and QS wave.

Results: Patients with facilitated PCI presented a rapid positive dynamics of ST-segment (decrease of ST-segment elevation in the secong point to 15,2 mm) compare to the second group (ST-segment elevation decreased to 8,5 mm). The dynamics of R waves was opposite: decrease of agebraic sum of R-waves in the first group was more evident compare to the second group, however those changes were less significant. There was no significant variability in dynamics of number of leads with pathologic Q-waves and QS-waves.

Conclusions: Facilitated PCI significantly accelerate dynamics of focal ischemic changes, reducing diameter of pereinfarction zone (more rapid ST-segment dynamic). Facilitated or primary PCI has no sagnificant effect on the size of necrozis.
