Changes of hemodynamics.

Table 1 Results were taken immediately at baseline, 1 hour and LAD occlusion. The values of SBP, DBP and HR were all not significantly different between the two groups. DBP, diastolic blood pressure; HR, heart rate; SBP, systolic blood pressure.Changes of hemodynamics.表1的结果采集于基线即刻、1小时以及左前降支动脉（Left Anterior Descending artery, LAD）闭塞即刻。两组的SBP、DBP及HR均无显著组间差异。其中DBP为舒张压（diastolic blood pressure），HR为心率（heart rate），SBP为收缩压（systolic blood pressure）。本部分内容围绕血流动力学变化展开。
