与缺血性心肌病不同,非缺血性心肌病是指并非由冠状动脉(冠脉)管腔狭窄导致心肌缺血引起,而是由诸如感染、免疫系统异常、毒素损伤、血流动力学相关机制、先天性遗传因素引起心肌病变,最终出现临床心力衰竭(心衰)表现的一类疾病。由于其病因复杂、发病机制并不明确,诊断也较为困难,且目前对于这类患者心功能持续恶化的机制尚不明确,临床上也无很好的治疗和预防手段。现有研究认为,冠脉微循环障碍在心肌病患者心衰进展过程中可能起到至关重要的作用。这类患
Unlike ischemic cardiomyopathy, non-ischemic cardiomyopathy is caused by myocardial ischemia not caused by stenosis of the coronary (coronary) lumen, but rather by conditions such as infection, abnormalities in the immune system, toxin damage, hemodynamics Related mechanisms, congenital genetic factors cause cardiomyopathy, eventually appear clinical heart failure (heart failure) performance of a class of diseases. Due to its complex etiology, the pathogenesis is not clear, the diagnosis is also more difficult, and at present, the mechanism of these patients with worsening cardiac function is not yet clear and there is no good clinical treatment and preventive measures. Existing research suggests that coronary microcirculation disorders may play a crucial role in the progression of heart failure in patients with cardiomyopathy. Such suffering
