Objective To evaluate the value of acoustic densitometry (AD) in detecting myocardium damage of the left ventricle secondry to hypoxic pulmonary hypertension (PH).
目的探讨声学密度定量（AD）技术定量评价缺氧肺动脉高压（PH）后左室心肌损害的应用价值。
Result: To the viable myocardium of left ventricle, parameters of integrated backscatter have improved at the 3th day after operation , and have statistical significant ;
结果：左室存活心肌背向散射积分参数值于术后3天就有了改善，与术前相比有统计学意义；
A left ventricle perfusion model is proposed for studying time-dependent blood distribution in ischemic myocardium and its dependence on coronary perfusion pressure.
为了研究在舒张期提高冠脉灌注压对缺血区血流时相分布的影响，建立了一个左心室壁血流灌注仿真模型。
