The connections between key words in research papers produced by the SHB and its collaborators. On the left, we cover a wide range of forms of heart failure (blue boxes), myocardial repair and regenerations (red) the impact of atrial fibrillations (orange), and oxidative stress (lilac). These are compared to a wide range of healthy donor heart (black). On the right, we list research topics we focus on keywords arising from all >80 SHB publications (listed in the Supplementary reference) over the past two decades. The topics include changes in and modifications of sarcomeric protein (purple), cytoskeletal proteins (blue-green), and defects in myocardial membranes (green)
