The haemodynamic significance of asymptomatic ST segment depression has been assessed in patients with coronary artery disease by direct measurement of left ventricular end-diastolic pressure (LVEDP) or pulmonary artery end-diastolic pressure (PADP). Both techniques have demonstrated a rise in pressure during such episodes of ST segment depression recorded in the Coronary Care Unit, cardiac catheter and exercise laboratories or during ambulant activity. Thus silent or asymptomatic ST segment depression is associated with similar haemodynamic changes to that seen during angina pectoris and has considerable therapeutic implications.
通过直接测量左心室舒张末期压力（LVEDP）或肺动脉舒张末期压力（PADP），已对冠心病患者无症状ST段压低的血流动力学意义进行了评估。这两种技术均已证实在冠心病监护病房、心导管检查和运动实验室记录的此类ST段压低发作期间，或在日常活动期间，压力会升高。因此，静息性或无症状性ST段压低与心绞痛发作时所见的血流动力学变化相似，具有重要的治疗意义。
