Figure 3 Endomyocardial tissue from one normotensive patient (A and D), one hypertensive patient with diastolic heart failure (B and E), and one hypertensive patient with systolic heart failure (C and F). Sections were immunostained with an antibody anti-MMP-1 (A, B, and C) or an antibody anti-TIMP-1 (D, E, and F), and these molecules were identified in brown within the cardiomyocytes. Arrows highlight specific points. (Magnification: x100.) Abbreviations as in Figure 2.
