Within irreversibly injured (infarcted) regions microvascular perfusion can vary from nearly normal to nearly zero, even in the presence of an open infarct-related artery ('no-reflow').
      
Historically, non-invasive assessment of heterogeneous microvascular perfusion within myocardial infarcts has been problematic.

Effect of external counterpulsation(ECP) on cerebral and skin microvascular perfusion were observed in hemorhagic shock canines with Laser Doppler Flowmeter technique. ECP augmented mean aortic pressure and increased cerebral and skin microvascular perfusion obviously in hemorhagic shock canines. After administering all shed blood, though the mean aortic pressures of control and ECP groups were recovered nearly to the basic level, the increase of microvascular perfusion in ECP groups was higher significantly...

Effect of external counterpulsation(ECP) on cerebral and skin microvascular perfusion were observed in hemorhagic shock canines with Laser Doppler Flowmeter technique. ECP augmented mean aortic pressure and increased cerebral and skin microvascular perfusion obviously in hemorhagic shock canines. After administering all shed blood, though the mean aortic pressures of control and ECP groups were recovered nearly to the basic level, the increase of microvascular perfusion in ECP groups was higher significantly than that in control groups. The results indicated that pre-treatment with ECP during the shock period could improve microcirculatory disorder effectively and then be beneficial to microvascular perfusion during the resuscitation.

应用激光多普勒测定微血管血流灌注技术,观察体外反搏提高灌注压力对失血性休克犬大脑皮层及皮肤微血管血流灌注的作用。结果显示,体外反搏可明显提高休克犬主动脉平均压力,增加休克犬大脑皮层及皮肤微血管血流灌注。在回输失血复苏后,对照组和反搏组主动脉平均压力恢复接近失血前水平,但反搏组微血管灌注的回升却明显高于对照组。结果提示体外反搏在犬失血性休克期预处理能改善其微循环障碍,有利于复苏期微血管的灌注

Objectives: Microvascular blood perfusion detected by Laser Doppler Flowmetry (LDF) during reactive hyperaemia was applied to reflect the microvascular diastolic dysfunction and to assess the therapeutic effect of enhanced external counterpulsation(EECP) on the dysfunction in patients with coronary artery disease(CAD). Methods: Laser Doppler Flowmetry (LDF) was used to measure the microvascular blood perfusion of forearm skin in subjects (n=58) with known coronary artery disease, hypercholesterolaemia and smoking before and during reactive hyperaemia (with increased flow causing endothelium-dependent dilation). The increased microvasular perfusion against basic level during reactive hyperaemia was used to evaluate microvacular diastolic function. Results: The microvascular diastolic function was much reduced in patients with known CAD and decreased in hypercholesterolaemic subjects and smokers for comparison with control group(1 83±0 37, 2 63±0 51,3 19±0 56 to 3 56±0 36 P<0 01, 0 01, 0 05) The dysfunction was improved in patients with CAD after the treatment of EECP than that before the treatment (2 45±0 43 to 1 83±0 37, P<0 01). Conclusion: The results showed that LDF could test the different microvascular dysfunction in patients with CAD, hypercholesterlaemic subjects and smoker. The treatment of EECP could improve microvascular diastolic dysfunction in patients with CAD.

Objective: This study assess the different pattern of coronary micro-vascular perfusion estimated by myocardial per-fusion using second harmonic myocardial contrast echocardiography by injecting leviosl from venous. Methods: 36 individuals underwent coronary artery angiography and myocardial contrast echocardiography(MCE) . The diseased arteries were Classified as three groups according to the perfusion score. Results: There were significant difference between the myocardial perfusion score index and coronary artery stenosis rate among three groups.when coronary stenosis were less than 75%,the myocardial perfusion was normal,but when coronary stenosis increased,myocardial perfusion become abnormal.There are 8 total occluded arteries, the myocardial perfusion were different because of different collateral circulation. Conclusions: MCE was an effective method for detecting myocardial perfusion which showed the different coronary perfusion and the integrity of coronary micro-vascular structure. So it aid to detect the myocardial perfusion supplied by microvascular perfusion which could not showed by coronary angiography. When myocardial perfusion was damaged, MCE can suggest coronary artery disease and its severity, but one should be careful about coronary colleteral circulation, this may affect the accuracy of estimating coronary artery disease. When coronary artery angiography showed diseased coronary artery, MCE could be used to evaluate the collateral circulation.

目的:本文获取冠状动脉血流变化所致的心肌灌注类型,以了解冠脉的微血管血流灌注变化。方法:36人先后完成冠状动脉造影,静脉注射声学造影剂利声显(Levovist),通过超声二次谐波技术获取心肌灌注图像,按心肌灌注积分指数将病人分为三组。结果:三组病人的冠状动脉狭窄程度、心肌灌注积分指数明显差异(P<0.001),冠状动脉狭窄度<75%者,病人心肌灌注多为正常,随着冠状动脉狭窄程度加重,出现不同程度的心肌灌注异常。8例完全阻塞的冠状动脉有不同的冠状动脉侧支循环表现为不同的心肌灌注类型。结论:静脉心肌声学造影是反映心肌灌注的有效方法,能够反应冠状动脉血流的改变及微循环结构的完整性变化,从而弥补冠状动脉造影仅能显示心外膜下的冠状动脉而无法观察毛细血管水平的心肌灌注之缺限。当心肌灌注不良时,MCE能提示冠状动脉病变的存在,及其严重性,但要注意侧支循环对心肌灌注之影响,可影响对冠脉病变程度判断的精确性。冠状动脉造影确定某支冠脉病变时,MCE心肌灌注有助于评价侧支循环状态。
