  coronary
These proteins may be involved in cardiovascular injury, and could play an important role in the treatment of coronary heart disease.
      
Evaluation of the effect of myocardial perfusion after percutaneous coronary intervention in coronary artery disease by using in
      
Detection of abnormal myocardial perfusion is crucial to the prognosis of patients with coronary artery disease (CAD) after they have undergone percutaneous coronary intervention (PCI).
      
No difference was found in CTFC between the coronary artery stenosis group and the normal group.
      
Thus, the IC-MCE method is of great value to coronary artery disease (CAD) patients undergoing PCI, especially for those with acute myocardial infarction (AMI).

Eight patients with congenital coronary A-V fistula were operated during 1957-1979.

本文报告8例先天性冠状动脉瘘的手术治疗,5例症状完全消失,2例症状明显减轻,1例失访。对冠状动脉瘘的诊断、病理解剖、手术指征及方法进行了讨论。

Using self-designed counterpulsator,24 paired experiments were performed in 9mongrel dogs.The aortic and left atrial pressures were monitored,and coronary sinuswas cannulated via right atrium for measuring blood flow and for blood sampling.Each paired experiment included 30 min normal heart beating which served as con-trol and 30 min of counterpulsation.After counterpulsation,the average decrease oftension time index was 1044.30±221.47 mmHg.sec/min,and the average increase ofdiastolic pressure time index(DPTI)was...

Using self-designed counterpulsator,24 paired experiments were performed in 9mongrel dogs.The aortic and left atrial pressures were monitored,and coronary sinuswas cannulated via right atrium for measuring blood flow and for blood sampling.Each paired experiment included 30 min normal heart beating which served as con-trol and 30 min of counterpulsation.After counterpulsation,the average decrease oftension time index was 1044.30±221.47 mmHg.sec/min,and the average increase ofdiastolic pressure time index(DPTI)was 660.56±158.31 mmHg.sec/min.The incrementof endocardial viability ratio was 0.94±0.12.The coronary sinus blood flow wasincreased from 20.38±1.77 to 24.50±1.70 ml/min/100g and myocardial oxygen con-sumption increased from 2.41±0.28 to 2.98±0.32 ml/min/100g.The mean incrementof myocardial lactate extraction was 0.58±0.27 mg/min/100g.The coefficient of cor-relation(r)between DPTI and coronary sinus flow was 0.41.All these were statisticallysignificant.The data suggested that arterial counterpulsation could increase coronaryblood flow,activate heart function depressed by surgical stress and prevent subendoeardialischemia

本文报道用助搏反搏器对9只狗作动脉反搏,观察全麻下正常动物心脏在反搏前后的血液动力学与代谢变化。在反搏后,张力时间指数下降,舒张压时间指数增加,心内膜活力比率增加,冠状窦流量增加,心肌耗氧量增加,经统计均有显著意义,心肌乳酸摄取量亦有增加。实验结果提示反搏可使正常心脏冠状血流量增加,心肌细胞摄取更多的氧和乳酸,使受抑制的心肌细胞功能恢复;有利于防止手术时心内膜下缺血等并发症。

IABP was carried out in 7 dogs with our own made balloon and an improved home-made counterpulsation pumping device. The hemodynamio parameters taken just before and during IABP in each dog were compared and treated statistically. The results of our studies showed that balloon pumping caused (1) a highly significant elevation in the mean aortic diastolic pressure (MADP) of 19.9 mmHg (P< 0.001) and a 19.6% increase of blood flow in the circumflex branch of the left coronary artery (P<0.001); (2) a highly...

IABP was carried out in 7 dogs with our own made balloon and an improved home-made counterpulsation pumping device. The hemodynamio parameters taken just before and during IABP in each dog were compared and treated statistically. The results of our studies showed that balloon pumping caused (1) a highly significant elevation in the mean aortic diastolic pressure (MADP) of 19.9 mmHg (P< 0.001) and a 19.6% increase of blood flow in the circumflex branch of the left coronary artery (P<0.001); (2) a highly significant lowering of 8 mmHg in the peak aortic systolic pressure (P<0.001), and of 20.1 mmHg in the peak left ventricular systolic pressure (P<0.001) and a 12.9% reduction in the peak rate of change of left ventricular pressure (dp/dt max) (P<0.001); (3) a highly significant reduction of 3.5 mmHg in the left ventricular end diastolic pressure (P<0.01); (4) a significant increase of 25.3 ml/min in the cardiac output (P<0.05); and (5) a 78% increase in the collateral blood flow in the ischemico myocardium distal to the ligation (P< 0.05).It was concluded that IABP in dogs with our device increases coronary perfusion pressure and coronary arterial blood flow. It also improves the collateral circulation distal to the occluded coronary artery, and lessens the left ventricular after load.The hemodynamic effects of IABP observed in this experiment were comparable with those reported in the literature. The safety of IABP with this device has also been testified.

本文总结了用国产装置对7头犬进行主动脉内气囊反搏的实验研究。通过反搏和停反搏的对比观察,表明用该装置进行反搏能提高冠状动脉的灌注压和血流量,改善受阻冠状动脉远端的侧支循环,并能减轻左室后负荷。其血液动力学效应与国外文献报道相仿。同时证明该装置的安全性能良好。
