目的目的观察并发有肺水肿的右冠状动脉闭塞患者的临床特点,并对其发病机制进行探讨。方法以文献研究法总结现有文献对该疾病发病机制的研究成果,以此为基础选取该疾病患者病例。针对其影像学检查结果、临床表现等进行分析。结果果所选患者病情进展速度较快,以抗心衰疗法治疗无明显改善。无心室间隔运动异常以及心室扩张现象,左冠状动脉狭窄程度较轻,而右侧几近闭塞,有严重的肺水肿症状;其发病机制与交感神经兴奋过度以及炎性反应有关。结论导致并发肺水肿的原因与肺泡上皮细胞被炎性因子损伤,以及交感神经释放儿茶酚胺相关。
Objective To observe the clinical characteristics of patients with right coronary artery occlusion complicated by pulmonary edema and to explore its pathogenesis. Methods To summarize the research results of the existing literature on the pathogenesis of this disease based on the literature research method, and to select the patients with this disease based on this research. For its imaging findings, clinical manifestations and other analysis. Results Results Selected patients progress faster, no significant improvement with anti-heart failure therapy. No ventricular septal motion abnormalities and ventricular dilatation, left coronary artery stenosis less, while the right side of the nearly occlusion, severe pulmonary edema; its pathogenesis and sympathetic hyperactivity and inflammatory response. Conclusions The causes of pulmonary edema complicated by the inflammation of the alveolar epithelial cells are inflamed as well as the sympathetic release of catecholamines.
