Viagra helps ailing hearts to recover in a surprising way – by making them less stiff, scientists have learned.

The impotency drug causes too-rigid heart chamber walls to become more elastic.

The research explains how Viagra might benefit patients with diastolic heart failure. People with the condition have abnormally inflexible ventricles, the heart’s major pumping chambers, that do not fill sufficiently with blood. This leads to blood ”backing up” in the lungs and breathing difficulties…

Scientists found that Viagra activates an enzyme that causes a protein in heart muscle cells to relax…

The drug’s active ingredient, sildenafil, inhibits an enzyme involved in the mechanism that regulates blood flow. However, the enzyme is slightly different in different parts of the body.

But, then, you already knew that.
