Pathological features of biopsied myocardium in patients clinically diagnosed with peripartum cardiomyopathy.
The etiology of peripartum cardiomyopathy (PPCM) is unknown. Therefore, we evaluated the etiology of patients clinically diagnosed with PPCM using endomyocardial biopsy. We studied five patients diagnosed with PPCM following endomyocardial biopsy (age, 28-42 years; mean age, 35 years). Biopsied samples were evaluated using microscopy, including immunostaining and electron microscopy. The pathological findings were as follows: myocardial hypertrophy, myocardial fibrosis, and cell infiltration. Two patients were diagnosed with lymphocytic myocarditis, one with eosinophilic myocarditis, one with hypertensive heart disease, and one with a combination of hypertension and myocarditis. Endomyocardial biopsy suggested that the causes of PPCM were varied and related to myocarditis and myocardial overload due to hypertension.
期刊介绍：
Medical Molecular Morphology is an international forum for researchers in both basic and clinical medicine to present and discuss new research on the structural mechanisms and the processes of health and disease at the molecular level. The structures of molecules, organelles, cells, tissues, and organs determine their normal function. Disease is thus best understood in terms of structural changes in these different levels of biological organization, especially in molecules and molecular interactions as well as the cellular localization of chemical components. Medical Molecular Morphology welcomes articles on basic or clinical research in the fields of cell biology, molecular biology, and medical, veterinary, and dental sciences using techniques for structural research such as electron microscopy, confocal laser scanning microscopy, enzyme histochemistry, immunohistochemistry, radioautography, X-ray microanalysis, and in situ hybridization.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
