Targeted Micro-Bubbles Detect Artery Inflammation

Dec 17, 2012

A procedure involving targeting micro-bubbles to detect artery inflammation in pigs has proven to be beneficial for humans, as well. Isabelle Masseau, an assistant teaching professor in the MU College of Veterinary Medicine, says that this procedure may help detect patients with heart disease or who are at risk for strokes before those ailments become too serious by monitoring artery inflammation, as that is an early warning sign of health problems. She says this procedure may also help monitor the effectiveness of artery inflammation treatments. Masseau’s research has contributed to the Mizzou Advantage initiative One Health, One Medicine.

Heart disease is a leading cause of death throughout the world. Doctors say that it is important to detect heart disease early before it becomes too serious. Now, researchers at the University of Missouri have found a way that they believe could help detect heart disease before it progresses too far as well as identify patients who are at risk for strokes.

In a study published in Medicine and Science in Sports and Exercise, Isabelle Masseau, an assistant teaching professor in the MU College of Veterinary Medicine, found that she could use targeted micro-bubbles to detect artery inflammation in pigs. She says that this procedure may help detect patients with heart disease or who are at risk for strokes before those ailments become too serious by monitoring artery inflammation, as that is an early warning sign of health problems. She says this procedure may also help monitor the effectiveness of artery inflammation treatments.

“It can be very difficult to detect early signs of heart disease, especially without the use of invasive procedures,” Masseau said. “Doctors often have to wait until serious symptoms occur, such as chest pain or heart attacks, before they are aware of a problem, and many times that is too late. Targeted micro-bubbles have the potential to be able to detect early signs of heart disease very non-invasively.”

Early signs of heart disease include inflammation on the insides of arteries, which leads to plaque buildup that could eventually result in heart attacks. Masseau was able to attach specific antibodies to tiny bubbles and then inject those bubbles into pigs with heart disease. The antibodies were able to seek out the inflammation in the pigs’ arteries and attach themselves, along with the micro-bubbles, to the inflammatory sites. Then, using an ultrasound machine, Masseau was able to detect the targeted micro-bubbles that had gathered in the arteries of pigs. She says this is the first time the procedure has been successful in large animals. More…
