[Retracted] Improved Cardiac Function and Attenuated Inflammatory Response by Additional Administration of Tirofiban during PCI for ST-Segment Elevation Myocardial Infarction Patients

Table 2

Myocardial perfusion and ST-segment elevation changes were compared to reflect immediate efficacy of PCI between the PCI + tirofiban and PCI groups prior to and post-PCI.

	PCI + tirofiban group	PCI group
TIMI grade (n (%))	56 (90.32%)	59 (95.16%)	0.300
No-reflow (n (%))	3 (4.84%)	7 (11.29%)	0.187
Total CTFC (mean ± s.d.)	15.88 ± 5.11	22.47 ± 6.26	<0.001
CTFC of LAD (mean ± s.d.)	17.12 ± 5.75	22.14 ± 6.25	<0.001
CTFC of LCX (mean ± s.d.)	13.97 ± 2.10	21.01 ± 4.89	<0.001
CTFC of RCA (mean ± s.d.)	15.76 ± 2.19	20.54 ± 4.22	<0.001
TMPG3 (n (%))	42 (67.74%)	31 (50.00%)	0.047
ST-segment depression > 50%	50 (80.65%)	44 (70.97%)	0.208

A total of 124 patients with STEMI were randomly assigned to PCI + tirofiban and PCI groups, 62 cases per groups. TIMI, thrombolysis in myocardial infarction; CTFC, corrected TIMI frame count; LAD, left anterior descending artery; LCX, left circumflex artery; RCA, right coronary artery; TMPG, TIMI myocardial perfusion grade.
