Collagen in cardiac hypertrophy and dilation
WebThe mechanisms of cardiac remodeling, particularly those underlying the transition from stable hypertrophy to cardiac dilatation and ultimately to overt HF, remain unclear. WebEnlargement of the cardiac silhouette (Figure 6-46) can be seen with pericardial effusion, myocardial hypertrophy or inflammation, chamber dilatation, cardiac or pericardial masses, and aneurismal dilatation. j A rounded, globoid cardiac silhouette is suggestive of pericardial effusion, but accurate confirmation and differentiation between ...
