Quantitation of myocardial fibrosis and its relation to function in essential XXXX and @entity1121 .

@entity1 @entity101 @entity82 @entity1121
Myocardial @entity82 is an important microscopic feature of @entity1121 . To determine whether @entity82 in @entity1121 and essential @entity101 differ in quality or quantity, and to determine whether @entity82 affects cardiac function directly, we measured the percentage of @entity82 in @entity1 of both categories and compared the severity of @entity82 with several cardiac functions. Left and right ventricular endomyocardial biopsies were performed in 25 @entity1 with essential @entity101 and in 19 @entity1 with @entity1121 . Interstitial @entity82 was classified into four different microscopic types, and the percentage of total and of each type was calculated using the point-counting method. Although the percentage of total @entity82 was similar between the two groups, the type of @entity82 was different. There was no correlation between the percentage of total @entity82 and the mean size of myocytes in either group. Although there was a significant correlation between the percentage of total @entity82 and the thickness of the interventricular septum in @entity1121 , such correlation was lacking in @entity101 . There was no correlation between the percentage of total @entity82 and the ejection fraction, cardiac index, or left ventricular end-diastolic pressure in either group. We concluded that the amount of myocardial @entity82 in @entity1121 is no greater than that in essential @entity101 , but the type of @entity82 is different. Furthermore, in subjects in whom the ejection fraction is normal or only slightly decreased, @entity82 does not influence global cardiac functions.
