目的探讨右室心肌梗死对急性下后壁心肌梗死预后的影响。方法对比分析自2002年2月-2006年2月在我院住院治疗的42例合并右室心肌梗死的急性下后壁心肌梗死(IWMI合并RVMI组)的患者与40例单纯下后壁心肌梗死(IWMI组)的患者,在住院期间及出院后病死率及心衰、心律失常等并发症发生率的差异。结果经研究得出急性下后壁心肌梗死合并右室心肌梗死时与单纯急性下后壁心肌梗死对比,患者院内病死率(29%对5%,P〈0.01)及心律失常、心衰、心源性休克等主要并发症的发生率(67%对29%,P〈0.01)均明显高于单纯急性下后壁心肌梗死的患者。经1-4年随访,合并右室心肌梗死的患者出院后病死率(35%对16%,P〈0.05)及心衰、心律失常等并发症的发生率(75%对36%,P〈0.05)均明显增高。结论合并右室心肌梗死的急性下后壁心肌梗死患者预后不良。 相似文献

目的 探讨飞行员冠状动脉痉挛(coronary artery spasm,CAS)致急性心肌梗死(acute myocardial infarction,AMI)的临床特征、诱发因素、诊断、治疗及医学鉴定. 方法 分析1例直升机飞行员冠状动脉痉挛致急性心肌梗死的病史、临床诊断、治疗过程及医学鉴定结论,并进行相关文献复习. 结果 本例飞行员有大量饮酒、吸烟、高血脂、疲劳等多种诱发因素;临床表现为心前区疼痛,胸闷,左肩及左臂发麻,出汗;心电图及心肌酶谱符合急性心肌梗死演变过程;冠状动脉造影未见粥样硬化狭窄,造影过程中发生左冠状动脉全程僵硬,左前降支中段95%狭窄,右冠状动脉僵硬;左、右冠状动脉内推注硝酸甘油后僵硬及狭窄缓解,考虑为冠状动脉痉挛,痉挛血管与心肌梗死部位吻合,证实心肌梗死由CAS所致.该飞行员病后无明显并发症,心电图大致正常,超声心动图正常.经积极控制诱发因素,其病情稳定,未再出现心前区不适等症状,能正常参加体能训练,地面观察半年后复查心电图正常,心功能等指标良好,最后结论:飞行合格.安全飞行1年余无任何不适. 结论 CAS可发生于冠状动脉无粥样硬化狭窄基础上,可引起心绞痛、心律失常、急性心肌梗北等;CAS与冠状动脉内皮功能受损有关,其发作往往有饮酒、吸烟、疲劳等诱因,对高危人群应采取积极预防措施. 相似文献

急性心肌梗死( acute myocardial infarction ,AMI)属急性冠脉综合征的严重类型,是由于冠状动脉狭窄或闭塞引起的心肌缺血和坏死。近年来随着冠脉介入的推广,对引起AMI的病因研究也越发深入。本文报道的AMI是由临床上较为少见的冠状动脉瘤(coronary artery aneurysm,CCA)的血管构型异常所诱发,故在该急症的诊断及治疗中也与以往传统的诊治有所区别。 相似文献

A patient presented with chest pain and S-T segment elevation in the anterior chest leads diagnostic of acute anterior myocardial infarction (MI). The non-invasive imaging studies showed no evidence of left ventricular anterior MI but showed a right ventricular MI. Coronary angiography showed an isolated right coronary artery obstruction. Occasionally, the ECG in acute right ventricular myocardial infarction may resemble an anterior MI. The differentiation is important from a therapeutic viewpoint. 相似文献

To identify high-risk subgroups of inferior myocardial infarction, 75 patients presenting with their first inferior infarction were investigated by sequential gated blood pool scans. The patients were divided into four groups based on the right ventricular function (RVF) and anterior wall motion (AWM) of the left ventricle by scan at the time of admission. A second blood pool scan was performed at ten days to evaluate RV and LV function. Thirty-eight patients had cardiac catheterization before discharge and all patients were followed up for one year to determine their clinical outcome. Depressed RVF and reduced AWM were observed in 26 (35%) (Group A); depressed RVF and normal AWM were found in 20 (27%) (Group B); reduced AWM and normal RVF in 10 (13%) (Group C); and normal RVF and AWM in 19 (25%) (Group D). The mean values of biventricular function (LVEF, RVEF) in groups A, B, C, and D were (44.9 +/- 8.4%, 32.5 +/- 9.9%), (59.9 +/- 8.6%, 34.5 +/- 8.0%), (44.9 +/- 15.7%, 48.2 +/- 3.3%), and (60.4 +/- 9.1%, 51.6 +/- 10.6%), respectively, at admission. In serial measurements, LVEF did not change significantly in any group, however, RVEF improved nearly 10 points in groups A and B at 10 days. Group A also had the highest incidence (82%) of left anterior descending coronary artery involvement, and the highest mean creatine phosphokinase levels (762 +/- 318 U/l): Furthermore, group A had a high incidence of major complications during their hospital course and high mortality during the one-year follow-up. These data clearly identified group A as a high-risk subgroup of patients with inferior infarction. 相似文献
