病毒性心肌炎和心肌病在临床上并不少见,国内自从开展心内膜心肌活检以来有关病理报告逐渐增多,为临床诊断和治疗提供了依据。但对其中伴有小血管病变者报道较少。本文报告3例伴有冠状动脉小血管病变的心肌病,其中1例为急性病毒性心肌炎,1例围产期心肌病和1例慢性病毒性心肌炎,均有心内膜心肌活检报告,并就其病理生理意义作一探讨。 Viral myocarditis and cardiomyopathy are not uncommon in clinic. Since the endocardial biopsy has been carried out in our country, pathological reports have been gradually increased, providing the basis for clinical diagnosis and treatment. However, there are fewer reports of small vessel lesions. This article reports 3 cases of coronary heart disease associated with coronary artery disease, including 1 case of acute viral myocarditis, 1 case of perinatal cardiomyopathy and 1 case of chronic viral myocarditis, endomyocardial biopsy were reported, and its pathological Physiological significance to make a discussion.
