接受 ECP 治疗并心导管监测者65例,其中27例主动脉根部测压显示反搏时舒张早期主动脉内压显著增高,可达15.6—17.6kPa,主动脉收缩压可降低0.667～3.33kPa。65例 Swan-Ganz 导管监测显示反搏后 PASP、PADP、PAWP、RAP 均有不同程度下降。以上表明 ECP可提高冠脉灌注压,减低心脏后负荷,改善心脏功能。19例急性心梗及7例陈旧性心梗者反搏过程亦具有同样效果。26例 ECP 时进行 ANF 监测,显示反搏30分钟时 ANF 浓度即有显著性增高,反搏60分钟时达峰值,停止反搏后仍高于反搏前。
ECP treatment and cardiac catheterization in 65 patients, of which 27 cases of aortic root pressure measurement shows that the early diastolic early aortic pressure during counterpulsation was significantly increased up to 15.6-17.6kPa, aortic systolic blood pressure can be reduced 0.667 ~ 3.33kPa. 65 cases of Swan-Ganz catheter monitoring showed that PPC, PADP, PAWP and RAP decreased with different degrees after counterpulsation. The above shows that ECP can improve coronary perfusion pressure, reduce cardiac afterload, improve cardiac function. 19 cases of acute myocardial infarction and 7 cases of old myocardial infarction counterpulsation process also have the same effect. ANF monitoring was performed in 26 cases of ECP, which showed that the concentration of ANF was significantly increased at 30 minutes of EECP. The peak value of EEC at 60 minutes was still higher than that before EECP.
