PET slightly overestimate extent of necrosis myocardium and can't distinguish transmural necrosis from subendocardial necrosis. PET高估心肌坏死范围,且不能判断心肌梗死的透壁程度。
Clinical analysis on acute left ventricular failure as the first manifestations of acute subendocardial myocardial infarction of 20 cases 急性左心衰竭为首发表现的急性心内膜下心肌梗死20例临床分析
The total dose of microspheres injected into the LCX of every dog was ( 3.43 ± 0.38) × 104. Finally, subendocardial infarction confirmed by TTC staining occurred in 16 segments of these abnormal perfusion segments. 结果冠脉回旋支平均累积注射(3.43±0.38)×104微球后,心肌造影发现18节段左室壁内膜下心肌灌注异常,其中16节段发生内膜下梗死。
Nursing of the patients with acute subendocardial myocardial infarction 急性心内膜下心肌梗塞患者的护理特点
Relation between subendocardial myocardial blood flow reserve and regional wall motion abnormalities at rest and during stress in dogs with chronic coronary stenoses 慢性冠状动脉狭窄犬静息和负荷时室壁运动异常与心内膜下心肌血流储备的关系
Purpose: This study was designed to investigate the value of myocardial contrast echocardiography ( MCE) for measuring the coronary blood flow reserve and subendocardial perfusion. 目的:探讨心肌声学造影定量冠脉血流储备及心内膜下心肌灌注的意义。
Experimental Study of Assessing Coronary Blood Flow Reserve and Subendocardial Perfusion by MCE 心肌声学造影估测冠脉血流储备及心内膜下心肌灌注的实验研究
Under normal condition, the density of steady state outward potassium currents of subepicardial myocytes was significantly greater than that of subendocardial myocytes; 在正常条件下,心外膜下心室肌细胞稳态外向钾流密度显著大于心内膜下心室肌细胞。
CTD was introduced to observe subendocardial myocardial VG at baseline, during ischemia and with DOB infusion. 以CTD观察心内膜下心肌缺血及应用DOB后心内膜下心肌的VG变化。
Under ischemia condition, the notch of action potentials of subepicardial myocytes disappeared and the APD was shortened even more, compared with that of subendocardial myocytes; 在缺血条件下,心外膜下的心室肌细胞动作电位复极1期后切迹消失,且APD缩短程度明显大于心内膜下的心室肌细胞。
Conclusions Acute subendocardial ischemia/ infarction in dogs could be successfully induced by intracoronary injection of PVA microspheres with standard catheterization technique under ultrasound guidance. 结论超声引导下经导管冠脉注射PVA微球可以诱发犬急性内膜下心肌缺血和梗死。
Ultrastructural Changes of Subendocardial in Diabetic Patients 糖尿病患者心内膜下心肌的超微结构改变
Influence of valve prosthesis type on the recovery of ventricular dysfunction and subendocardial ischaemia following valve replacement for aortic stenosis 主动脉瓣狭窄瓣膜置换术后,生物瓣膜类型对改善心室功能不全和心内膜下缺血的影响
Conclusions In presence of chronic coronary stenosis, RWMA during rest and stress is related to subendocardial MBF reserve. 结论在慢性冠状动脉狭窄中,静息和负荷时RWMA与心内膜下MBF储备有关。
Although indomethacin and humic acid did not improve intestinal reperfusion damage, they significantly alleviated the subendocardial damage after ischemic intestinal reperfuison; 消炎痛和黄腐酸虽不能改善缺血小肠的再灌注损伤,但显著减轻了缺血小肠再灌注后的心内膜下出血;
Results: In normal adult goat ventricle, subendocardial type ⅰ bundle cells proliferated and evolved into Type ⅱ bundle cells or cardiomyocyte forming unit ( CMFU). 结果:正常成体羊心室内膜下Ⅰ型束细胞分裂增生为Ⅱ型束细胞团或心肌生成单位。
Clinical and pathological features of patients with repeated attacks of subendocardial myocardial infarction 反复心内膜下心肌梗塞的临床和病理特点
The HE staining showed that the ischemia and necrosis area in the subendocardial myocardium present weak staining, and mainly focused on the left ventricular wall and the interventricular septum which near the endocardium and the inner layer of myocardium, especially the cardiac apex. HE染色显示心内膜下出现心肌细胞缺血坏死区,HE染色呈浅染区。主要集中于左心室壁和室间隔靠近心内膜及内层心肌处,尤以心尖部为重。
