Abstract
Collagen is an essential part of the cardiac interstitium. Collagen subtypes, their location, total amount and the architecture of the fibrillar network are of functional importance. Architecture in terms of density of the fibrillar network is assumed to be reflected by the intensity of immunohistochemical staining of collagen. The aim of this study was to evaluate a video-based microdensitometric method for quantifying density expressed as absorbance of collagen subtypes I and III stained with an indirect immunoperoxidase method in myectomy specimens of patients with hypertrophic obstructive cardiomyopathy. Various factors influencing the immunohistochemical staining product and the technical properties of the image analysis system were investigated. Linearity between collagen concentration and the absorbance of the immunohistochemical staining product was demonstrated for collagen I using a dot-blot technique. Immunohistochemical collagen staining and density measure ment were easily reproducible. The cardiac disability of the patients was assessed according to the New York Heart Association (NYHA) criteria. There was a significant increase in collagen type I density with higher NYHA class, whereas no significant association was found for total collagen area fraction. Thus, video-based microdensitometry gives further insight into the structural remodelling of myocardial collagens and reveals their significance in the process of heart failure in hypertrophic cardiomyopathy.
