Strong Support
In rats with diabetes, when their heart relaxes better between beats, it’s more because the heart muscle itself becomes less stiff from changes in a protein called titin—not because there’s less scar tissue from collagen.

The study found that in diabetic rats, better heart relaxation was more tied to changes in a spring-like protein called titin than to scar tissue (collagen), and this was seen when the rats did aerobic exercise — which supports the idea that titin matters more than collagen for heart stiffness in diabetes.
