MicroRNAs could heal broken hearts

Researchers in Italy have found microRNAs (miRNAs), tiny fragments of genetic material, that regenerate tissue in mouse hearts.

Doctors overuse invasive heart test, study says

Doctors use a 50-year-old invasive heart imaging test known as a left ventriculography or left ventriculogram much too often, a Stanford University School of Medicine study concludes.

Gene discovered that regulates the timing of our tickers

A scientist with the Gladstone Institutes, a nonprofit biomedical research foundation affiliated with University of California, San Francisco, has discovered how a gene regulator controls a mechanism

Carbon nanotube patch could regenerate heart tissue after attack

Time again to consider the carbon nanotube, that seemingly magical material that has been put forth as an answer to everything from semiconductor interconnects to drug delivery devices to

Heart failure progression is in the PINK1 gene

Heart failure, the most-common cause of hospitalization in North American adults, might be turned on by simply flicking a switch--a "pink" one. It's actually a protein switch called PINK1, and it can

Cardiac gene names get a heart-y laugh

Nicholas Wade of The New York Times has a little fun with the names scientists give genes when they're discovered in lab animals. Hippo, Warts, Merlin, Yorkie, Scalloped, Shaggy, Frizzled,

Stem cells shrink enlarged hearts, rejuvenate scar tissue

Songwriters may think that only love can mend a heart, but University of Miami cardiologists found that stem cell therapy can do it, too. In a small, preliminary human study, the researchers used

Scientists generate lab-dish human heart model

Potential heart treatments could be tested on human cells in a lab dish, rather than in mice, thanks to new stem cell technology. Stanford University researchers used skin cells from children with

Investigators use microthread to stitch stem cells into place

Investigators at the Worcester Polytechnic Institute have devised a new approach to delivering stem cells right where they are needed, raising the possibility of success for treating damaged cardiac

Stem cell patch heals a broken heart

Chalk up another victory for stem cells: a study shows they can mend a broken heart--literally. According to researchers at the University of Cincinnati the recipe calls for infusing a patch with
