Trapping Enzyme Inhibitors in a Responsive Hydrogel (image) University of Pennsylvania Share Print E-Mail Caption Each patient responds to heart attacks differently and damage can vary from one part of the heart muscle to another. Penn researchers have developed a way to address this variation via a material that can be applied directly to damaged heart tissue. Using a gel that degrades away in the presence of damaging enzymes, releasing inhibitors to quell their overactivity, the researchers demonstrated promising in vivo results for limiting the onset of the tissue degradation that leads to congestive heart failure.
