Objective The objective of this study was to evaluate the clinical significance of coronary stenting in patient aged more than 70 years old.Methods The results of coronary stenting (14 with acute myocardiac infarction) were analyzed and compared them to 36 patients aged from 50 to 60 years old. Results The clinical success rate of coronary stenting for elderly group was 96.8%. The reanginal rate during 3 to 44 (21 ± 14) months' follow up of was 23% . No significant difference in the success and reanginal rate...

No significant difference in the success and reanginal rate was observed between the two groups and no death case was found in the 14 elderly patients with acute myocardiac infarction.Conclusion Our data suggest that coronary stenting is a very safe and effective method of coronary revascularization in elderly patients.

目的 研究70岁以上冠状动脉内支架置入术的临床价值。方法 对31例(14例急性心肌梗死)≥70岁和36例50~60岁冠状动脉内置入支架的冠心病患者进行比较。结果 高龄组支架置入术成功率为96.8%,随访3~44(21±14)个月,心绞痛再发率23%,与对照组比较差异无显著性;14例高龄心肌梗死患者急性期冠状动脉内置入支架无一例死亡。结论 高龄患者冠状动脉内支架置入即刻与远期临床效果满意,是冠状动脉血管重建术安全而有效的方法。

AIM:To investigate the ability of stem cell factor(SCF)-mobilized bone marrow stem cells homing to infarcted myocardium and its differentiation in aged rat, and the influence on heart function. METHODS:Left anterior descending coronary arteries were ligated to produce acute myocardial infarction(AMI) model in Wistar rats. Rats were divided into 3 groups: aged MI+mobilized group, aged MI group and young MI+mobilized group. Bone marrow stem cells were mobilized by SCF and home to the site of myocardial infarction....

AIM:To investigate the ability of stem cell factor(SCF)-mobilized bone marrow stem cells homing to infarcted myocardium and its differentiation in aged rat, and the influence on heart function. METHODS:Left anterior descending coronary arteries were ligated to produce acute myocardial infarction(AMI) model in Wistar rats. Rats were divided into 3 groups: aged MI+mobilized group, aged MI group and young MI+mobilized group. Bone marrow stem cells were mobilized by SCF and home to the site of myocardial infarction. Hearts were harvested from 24 hours to 4 weeks after AMI modeling for histopathological examination. Immunohistochemisty,HE stain were used to detect infiltration of CD34~(+)cells and the regeneration of myocytes. The CD34~(+) cell number before and after mobilization was determined with flowcytometry. Four weeks after modeling heart function each group was measured by using the biofunction laboratory system(BL-420E system). RESULTS:The number of CD34~(+)cells increased significantly in peripheral blood after mobilization of stem cells in aged and young MI+mobilized group. There were a great number of monocytes infiltrating with CD34 expression by immunohistochemisty in myocardial infarcted zone in aged and young mobilized rats. Compared with aged MI group, heart function in aged MI+mobilized group was improved significantly, but there were no marked differences between aged MI+mobilized group and young MI+mobilized group. 24 hours after modeling, a large amount of infiltrative monocytes and regenerative myocytes which were CD34 positive expression could be found in the infarction zones of the aged and young mobilized groups, while majority of the infiltrative inflammatory cells in aged MI group were neutrophils and there was less infiltrative cells and myocytes which were CD34 positive expression. 4 weeks after modeling, there were a plenty of scar in aged MI group, but not in aged and young MI+mobilized group. CONCLUSION:In aged rat AMI model, ability of bone marrow stem cells homing to infarcted myocardium increases after mobilization. SCF can mobilize many bone marrow stem cells to home to infarcted zones and differentiate to cardiomyocyte-like cells. The heart function is remarkably improved by regeneration of myocytes and protection of ischemic myocardial structure.
