Abstract：Objective To analyses the effects on left ventricular remodeling and heart function of primary and delayed PCI in acute myocardial infarction by contrast. Method The clinical data of 108 patients with acute myocardial infarction in our hospital from January 2012 to December 2015 was collected. All patients were divided into three groups according to treatments: the primary group(n=38) with primary PCI treatment; the delayed group(n=34) with delayed PCI treatment; the control group(n=36) with conservative treatment. The LAd, ESV, EDV, LVEF of the three groups in one week and 6 months after therapy were detected and compared. Then hemodynamic parameters, such as mPAP and mMPG of the three groups in one week and 6 months after therapy were collected, and recurrence of the three groups in 6 months after therapy were evaluated. Result In primary group and delayed group at 6 months after therapy, the LAd, ESV, EDV were apparently lower then these in control group, and LAd(34.04±5.10 mm), ESV(46.01±15.40 ml), EDV(114.24±25.68 ml) of primary group were lower then these of delayed group, P<0.05; The LVEF of primary group and delayed group in 6 months after therapy were statistically higher then these in control group, and LVEF(60.41±10.06%) of primary group were higher then that of delayed group, P<0.05; The mPAP and mMPG of primary group and delayed group in 6 months after therapy were markedly lower then these in another group, and mPAP(4.36±0.51 P/kD) and mMPG(0.98±0.36 P/kD) of primary group were remarkably lower then these of delayed group, P<0.05; Recurrences of AMI(7.89%) and heart failure(2.63%) of primary group were evidently lower then these of control group, P<0.05. Conclusion The primary and delayed PCI both can improve left ventricular remodeling and heart function of acute myocardial infarction, and the primary PCI can get better effects.
