A 3D-printed patch could help you recover from a heart attack

  A 3D-printed patch could help you recover from a heart attack Scientists have dreamed of easily patching up heart tissue in the wake of heart attacks, but there are always gotchas: for example, it's no mean feat to replicate the complex structures of real tissue. After the team tested its patch on a mouse, the rodent's heart saw a "significant increase" in functional capacity in the space of 4 weeks. Moreover, it eventually absorbed into the heart -- the team didn't have to perform follow-up operations to make sure it was a good fit.

Each year, more than 700,000 people suffer myocardial infarction, aka a heart attack. Thanks to medical advances, there are myriad ways for a doctor to get the blood properly pumping and save a person’s life. A cardiologist might give a patient medication to clear or loosen blockages.

Thanks to medical advances, there are myriad ways for a doctor to get the blood properly pumping and save a person’s life. A cardiologist might give a patient medication to clear or loosen blockages. Or a doctor might insert a catheter to remove the clot, or place stents in the artery so it stays open.

These interventions have vastly improved survival rates, but they don’t heal the damage caused by a cardiac event. The heart is really just one big muscle, and trauma to any muscle does some damage, which becomes scar tissue. Scar tissue on the heart means it functions far less optimally, which eventually leads to heart failure.

Short of a transplant, there isn’t a long-term option to fix a damaged ticker. But a team of researchers say they’ve come up with a high-tech solution that could revolutionize cardiology. Using 3-D printing technology, Brenda Ogle, an associate professor of biomedical engineering at the University of Minnesota-Twin Cities, has created a patch a doctor could apply to mend a patient’s broken heart.

“The concept is to imprint proteins that are native to the body,” says Ogle. “We’ve used stem cell–derived cardiac muscle—cardiac myocytes—and actually mixed those with other cell types needed for blood vessels.” This, she says, prevents what would otherwise happen naturally: The formation of a different type cells known as fibroblasts, which secrete scar tissue.

Ariana Grande Is ‘Broken’ After Concert Bombing: ‘From the Bottom of My Heart, I Am So Sorry’

  Ariana Grande Is ‘Broken’ After Concert Bombing: ‘From the Bottom of My Heart, I Am So Sorry’ Suspected terror attack at Manchester Arena in England killed 19 and injured at least 50 others."Broken. from the bottom of my heart, i am so so sorry. i don't have words," the singer tweeted.

No, this isn't another silly love song; new technology may help transform cardiology. Each year, more than 700,000 people suffer myocardial infarction, aka a heart attack. Thanks to medical advances, there are myriad ways for a doctor to get the blood properly pumping and save a person’s life.

Xkelet says its 3 D printed splint for fractures reduces muscle loss, peeling, and itching, and allows the patient to bathe. Using that concept, they decided to create a prototype and a company to market the eventual product, which they christened Xkelet, a 3 D - printed splint for helping heal broken bones.

Ogle and her team of 3-D printing experts, clinical cardiologists and stem cell engineers have successfully tried the patch on mice. First, the team induced cardiac arrest in the rodents. When they then placed the cell patch on a mouse, researchers saw a significant increase in the functional capacity of the organ after just four weeks. “We generated the continuous electric signal across the patch, and we can pace it: We can increase the frequency of beating up to three hertz, which is similar to a mouse heart,” says Ogle who, this past January, published the findings of their experiment in Circulation Research, a journal from the American Heart Association.

The results of the experiment were so inspiring that in June 2016 the National Institutes of Health awarded her team a grant of more than $3 million, so they can now give pigs heart attacks and fix them with the patch. However, it will take some time to see their innovation in surgical departments, since using biological products such as cells requires a long regulatory process and, of course, quality assurance.

“The replacement of muscle has been the holy grail for some time,” says Ogle. “Now we finally have the ability to take stem cells out of the body and develop the protocols to do that.”

Louis Tomlinson's mum begged him to mend friendship with Zayn Malik before she died .
Louis Tomlinson has revealed his mother's dying wish was for him and former One Direction bandmate Zayn Malik to be friends again. Johannah Deakin lost her battle with leukaemia in December (16) and now her singer son tells British tabloid The Sun, she desperately wanted him to reach out to Zayn, telling him "life is too short" to stay mad at old pals. Louis reveals he had not spoken to Zayn since he quit One Direction on tour in 2015. "My mum said, 'You’ve got to get back in contact with Zayn. Life’s too f**king short," Tomlinson recalls. "A mother’s intuition is just f**king crazy. It always felt supernatural to me. My mum always knew what I was feeling and what I wanted." "I can’t stand to hold a grudge with anyone. It doesn’t sit with me right," he tells the tabloid. Johannah, who was just 43 when she died, knew in her heart that Louis needed a jolt to pick up the phone and speak to Zayn. "I met up with him and it was nice," he explains. "Zayn was always good for me in the band because he was my go-to if I wanted to p**s around, lark around. I would always see the good in Zayn and also watch him shoot himself in the foot with some of his decisions, but he’s just a little misunderstood." Louis and Zayn were at the forefront on the biggest scandal surrounding the boy band - when they were caught puffing from a joint in an online video and joking about marijuana use.
