Heart
Although medical advances over recent years have seen the majority of people surviving heart attacks, the damage done to the heart muscle is irreversible. As a result, most patients eventually succumb to congestive heart failure, the most common cause of death in developed countries. Stem cells offer hope for achieving what the human body can’t do: mending broken hearts. Now researchers have built a scaffold that supports the growth and integration of stem cell-derived cardiac muscles cells. The scaffold supports the growth of cardiac cells in the lab and encourages blood vessel growth in living animals. Read More
A combination of nanotechnology and adult stem cells has been shown to destroy arterial plaque (atherosclerosis) in the heart of pigs. Pigs that received stem cells also showed signs of new blood vessel growth and restoration of artery function according to the study reported at the American Heart Association's Basic Cardiovascular Sciences 2010 Scientific Sessions – Technological and Conceptual Advances in Cardiovascular Disease.

When rest is important to a patient, being rigged up to a heart monitor or disrupted whilst they sleep and having a cold stethoscope placed on their chest isn’t ideal. To get around this problem, a team of scientists at the University of Sussex, UK have successfully developed sensors that are able to detect a heartbeat up to a meter away. The Electric Potential Sensors (EPS) are the world’s first electrical sensors able to monitor heartbeats accurately whilst patients relax in their bed, or rest at home. This breakthrough device gives medical teams and health workers the chance to administer patient-friendly monitoring with minimum impact on mobility or personal space. Read More
Sure, LED tattoos might look cool, but now scientists have found an even better use for flexible silicon technology. In what represents the first use of such technology for a medical application a team of cardiologists, materials scientists, and bioengineers has created and tested a new type of implantable device for measuring the heart’s electrical output that the team says is a vast improvement over current devices and could also mark the beginning of a new wave of surgical electronics.

The problem with a heart attack – apart from the obvious of course – is that you have very little time to get to an emergency room or doctor. A medical diagnosis in the first few hours - usually by undergoing an ECG – is critical to determine the severity of the arrhythmia or ischemia (heart attack) episode. Rather than dealing with crowded emergency rooms and overstretched MD’s, this simple to use pocked-sized device can give you an ECG reading on-the-spot. Read More
A portable magnetometer being developed at the University of Leeds could dramatically simplify and improve the process of diagnosing heart conditions. Its creators say its unprecedented sensitivity to magnetic fluctuations will allow the innovative cardiac scanner to detect a number of conditions, including heart problems in fetuses, earlier than currently available diagnostic techniques such as ultrasound, ECG (electrocardiogram) and existing cardiac magnetometers. It will also be smaller, simpler to operate, able to gather more information and significantly cheaper than other devices currently available. Read More
Stopping a heart from beating during surgery is a complicated and risky procedure. Robotic technology that predicts the movement of the heart as it beats, thereby enabling surgical tools to move in concert with each beat, could help cut the risks of such surgery by allowing surgeons to operate on a beating heart as if it were stationary.

Heart disease is the leading cause of death in many parts of the world, including the U.S., England and Canada, so it's not surprising that bioengineers at Duke University are excited by what they believe could be an important first step toward growing a living “heart patch” to repair damaged heart tissue. In a series of experiments using mouse embryonic stem cells, the bioengineers used a novel mold of their own design to fashion a three-dimensional "patch" made up of heart muscle cells, known as cardiomyocytes. The new tissue exhibited the two most important attributes of heart muscle cells - the ability to contract and to conduct electrical impulses. Read More
Finally, video-gamers whose parents told them that playing games would never help them get a job can point to research that proves them wrong – well, sort of, anyway. A new study by a University of Warwick researcher has demonstrated that scientists trying to model a range of processes could ‘borrow’ an Xbox chip to get all the power and capabilities they need, saving thousands of dollars on parallel processing hardware and/or countless man-hours.
