Obesity, diabetes, and sedentary lifestyle of the urban population has escalated the percentage of population suffering cardiac arrest. While healthcare equipment manufacturers have managed to develop tissue patches that can fix the damaged part, the longevity of the products has always been doubted since FDA approved it.
Now, biomedical engineers at the Duke University have managed to crease a completely functional artificial human heart muscle that is strong, big enough, and as electrically active as a healthy adult cardiac tissue.
According to biomedical engineering doctoral student at the University, Ilya Shadrin, nearly every therapy currently available is aimed at reducing the symptoms from the damage that the heart has already suffered, but very little to nothing is done by these approaches to replace the muscle that was lost as a result of the cardiac arrest. The newly engineered patch can ideally replace the lost muscle with the bioengineered tissues.
Growing Number of Cases of Heart Failure Prompted the Invention
Nearly 12 million patients who have gone through the surgery suffer from heart failure across the world but the new therapies developed at the Duke University. This study goes beyond a number of clinical trials currently underway that inject stem cells that are derived from bone marrow, heart, or blood, as less than one percent of injected cells survive to become cardiac muscle cells.
The newly developed heart patches can be installed over the deal muscle and promises to remain active for a much longer period of time, providing strength and smoothness for the electrical signals sent by the heart.
