Up until now, the only way to test the efficacy and side effects of heart medicines was to experiment on animals and human patients. A British doctor, Dr. Helen Maddock, has proposed a new method that could eliminate that unneeded testing. The technique involves removing a sample of a live human heart. The specimen is then attached to a “tiny rig,” which keeps it alive. Electrical impulses are sent through the heart sample, causing it to beat.

FierceBiotechResearch wrote in an article that this revolutionary process could potentially “provide the most realistic way to test the cardiovascular effects of drugs without using humans.” You can read the full press release here.

Hopefully, Dr. Maddock’s innovation will lead to better heart medicines. Medicines that could help those who’ve suffered cardiac injuries from prescription testosterone, for instance.
