comparison of lv function with myocardial structure ( endomyocardial biopsies ) has shown that in patients with compensated lv function and those with left heart failure ( ef less than 57 % , lvedp greater than 20 mm hg and/or cardiac index less than 2.5 l/min/m2 ) interstitial fibrosis ( if ) was increased to a similar extent ( 16 and 18 % ; normal less than 5 % ) , whereas muscle fiber diameter ( mfd ; normal less than or equal to 20 mu ) was larger ( p less than 0.05 ) in the patients with failure ( 30 mu ) than in those with preserved function ( 27 mu ) .
