Abstract | OBJECTIVE: METHODS: Forty-seven AMI patients who underwent PCI within 12 hours of onset and MBG was 0 - 1 were randomized to receive standard therapy [group B, n = 23, 18 males, mean age (62.72 +/- 11.48) years] or standard therapy plus intracoronary administration of anisodamine [200 microg/ml, group A, n = 24, 18 males, mean age (64.23 +/- 12.27) years]. The left ventriculography (LVG) was performed immediately and 6 months after PCI to measure the ventricular volume, LVEDP and wall motion score (WMS). Equilibrium radionuclide angiography (ERNA) was performed 1 week and 6 months after PCI to determine the parameters of left ventricular regional, global systolic function and systolic synchrony. Incidence of major adverse cardiac events ( MACE) during the follow-up was analyzed. RESULTS:
Anisodamine [(2530 +/- 340) microg/person)] was well tolerated by patients. The MBG remained unchanged in group B and significantly increased from grade 0.74 +/- 0.32 to grade 2.33 +/- 0.28 10 min after anisodamine injection in group B. Six months post PCI, LVESVI [(40.53 +/- 8.12) ml/m(2) vs. (50.32 +/- 8.26) ml/m(2)], LVEDVI [(80.13 +/- 9.74) ml/m(2) vs. (87.17 +/- 10.25) ml/m(2)], WMS [(8.24 +/- 1.31) vs. (10.23 +/- 1.82)] and LVEDP [(13.36 +/- 4.21) vs. (16.38 +/- 3.21) mm Hg, 1 mm Hg = 0.133 kPa] were significantly lower in group A compared with that in group B (all P < 0.05) while LVEF [(44.02 +/- 5.86)% vs. (38.52 +/- 5.18)%], PER [(1.86 +/- 0.09) EDV/s vs. (1.61 +/- 0.09) EDV/s] and PFR [(2.19 +/- 0.32) EDV/s vs. (1.78 +/- 0.17) EDV/s] measured by ERNA were significantly increased in group A compared with that in group B (all P < 0.05). (2) LrEF(2)-LrEF(8) in group A were higher by 13.96%, 25.02%, 30.36%, 22.86%, 27.67%, 22.07% and 18.71% respectively compared with that in group B. (3) Phase analysis showed that the left ventricular systolic synchrony parameters PS [(46.04 +/- 8.93) degrees vs. (53.19 +/- 162) degrees ], FWHM [(23.02 +/- 6.27) degrees vs. (25.02 +/- 5.31) degrees ] and PSD [(7.92 +/- 4.12) degrees vs. (11.76 +/- 4.11) degrees ] were also significantly lower in group A than that in group B (all P < 0.05). (4) During the 6 months of follow-up, the incidence of MACE in group A was significantly lower than that in group B (P < 0.05). CONCLUSION:
