In experimental ischemia/reperfusion porcine model, the development of ventricular fibrillation (VF) after reperfusion is very difficult to prevent by pre-treatment with anti-arrhythmic agent. In the present study, we tested propafenone, procainamide, metoprolol and its combination to prevent reperfusion VF. The hypothesis is that combined drug therapy may have greater anti-VF efficacy than either alone The proximal LAD was occluded for twenty minutes by intra-coronary balloon inflation.

In experimental ischemia/reperfusion porcine model, the development of ventricular fibrillation (VF) after reperfusion is very difficult to prevent by pre-treatment with anti-arrhythmic agent. In the present study, we tested propafenone, procainamide, metoprolol and its combination to prevent reperfusion VF. The hypothesis is that combined drug therapy may have greater anti-VF efficacy than either alone The proximal LAD was occluded for twenty minutes by intra-coronary balloon inflation. Drug prophylaxis was initated 20 minutes prior to LAD occlusion in each group. In 85 close chest anesthetized pigs, divided into seven groups, ①control, ②propafenone (1 mg/kg). ③metoprolol (4 mg/kg), ④combined propafenone and metoprolol, ⑤proeainamide (20 mg/kg iv within 2 min as initial dose follwed by 0.1 mg/kg/min as a maintenance dose over the entire experiment), ⑥combined procainamide and metoprolol, ⑦combined procainamide and propafenone with 12 pigs in each group except the control (n=13). Significant protection against reperfusion VF occurred only in group 2 (metoprolol) and group 4 (propafenone+metoprolol). In comparing with control, propafenone with metoprolol was found to be more effective in anti VF (0/12 vs 7/ 13, p<0.02) than the group of Metoprolol (1/12 vs 7/13, p<0.05) alone. Only 2 cases of reperfusion VF occurred in group 7 (propafenone with proeainamide).

以闭胸式冠状动脉缺血—再灌注实验模型,探讨普罗帕酮(Ic)、美托洛尔(Ⅱ)、普鲁卡因胺(Ia)及其联合用药对实验性再灌注心律失常的预防价值。85头猪分为7组:①对照组;②普罗帕酮(1 mg/kg);③美托洛尔(4 mg/kg);④普罗帕酮+美托洛尔;⑤普鲁卡因胺(20 mg/kg为冲击量,0.1mg·kg~(-1)/min为维持量);⑥普鲁卡因胺+美托洛尔;⑦普罗帕酮+普鲁卡因胺。除对照组为13头猪外,其余各组均为12头。实验结果:①单剂美托洛尔(1/12比7/13,P<0.05)和美托洛尔、普罗帕酮联合(0/12比7/13,P<0.02),有明显降低猪再灌注心室颤动的作用。②普鲁卡因胺和普罗帕酮联合仅发生2例再灌注心室颤动。③各组均未能制止再灌注持续室性心动过速和缺血性心室颤动。

Three cases of intra-coronary artery stenting were reported for acute closure or threatened closure in PTCA. The indications included:(1)Coronary artery closure or nearly closure with reduced flow and vessel wall abnormalities (dissection,intimal tears and irregular filling defects),(2)ECG ST segment elevation or depression,LVEDP increased and ABP depression,(3)chest pain.Two patients were implanted with Gianturco-Roubin stents,the other one with Palmaz- Schatz stent.All procedures were successful.None had acute thrombosis or other severe complica- tions.The authors also described the whole procedure in detail and discussed the clinical significance and special features of the intra-coronary artery stenting.The authors believe that intra-coronary artery stenting is very effective to manage acute closure in PTCA and that anticoagulant therapy is very important to the success of this technique.

作者报告了3例冠状动脉血管成形术(PTCA)术中发生急性血管闭塞,或严重内膜剥脱致血管夹层,形成威胁性闭塞时,采用冠状动脉内支架置入术治疗的结果。3例病人均为术中决定置人冠脉内支架,经快速抗凝等准备,一次放置成功。支架置入后残余狭窄为0~10%,获得了满意的管径增大效果。3例病人均无急性或慢性血栓形成的严重并发症,术后无心绞痛发作,临床经过顺利。作者认为冠脉内支架置入术,是处理PTCA术中急性血管闭塞的有效而快速安全的手段。作者还讨论了紧急情况下冠脉内支架置入术的具体操作及注意事项,认为充分适度的抗凝治疗是保证支桑置入成功的关键。

The purpose of this study was to determine the changes in coronary artery diameter (D), cross-sectional area ( CSA), blood velocity (V) and flow(F), using computer-assisted method after intra-coronary papaverine, and to assess the clinical significance of coronary flow reserve (CFR) in patients with essential hypertension and left ventricular hypertrophy. CFR was assessed as the velocity of the leading edge of the contrast medium moving down a coronary artery which approximates the velocity of coronary...

The purpose of this study was to determine the changes in coronary artery diameter (D), cross-sectional area ( CSA), blood velocity (V) and flow(F), using computer-assisted method after intra-coronary papaverine, and to assess the clinical significance of coronary flow reserve (CFR) in patients with essential hypertension and left ventricular hypertrophy. CFR was assessed as the velocity of the leading edge of the contrast medium moving down a coronary artery which approximates the velocity of coronary flow. F=CSA×V. CFR = F (after intracoronary pa-paverine)/F(before intracoronary papaverine). In 14 patients with hypertension and left ventricular hypertrophy, the F of the left anterior descending artery (LAD) and V and F of the right coronary artery (RCA) were higher than in 26 normal controls before papaverine administration. After intracoronary papaverine, the V and F increased for the two arteries and did not differ from those in normal controls. The CFR was lower in patients with hypertension (LAD: 2. 42±1. 24; RCA:2. 65±0. 50) than in normal controls (LAD:3. 91±2. 10; RCA: 5. 54±1. 97). Thus the reduced coronary flow reserve in patients with hypertension and left ventricular hypertrophy may be ascribed to the baseline increase in coronary blood perfusion.

用电子计算机分析造影剂前缘移动平均速度和冠脉内径测定冠脉血流,发现高血压伴左室肥厚组(14例)静息时左前降支血流量和右冠脉血流速度、血流量高于血压正常对照组(26例)。注射罂粟碱后,高血压组两支血管的血流速度和血流量与对照组相似,但血流储备明显减低。因此,高血压左室肥厚患者的冠脉血流储备减低,可能与这些患者静息时冠脉血流增高有关。
