Space travel disrupts normal rhythm in heart cells

Heart tissue samples that spent 30 days at the International Space Station appear to have been weakened by the low gravity conditions in space. This finding has implications for the heart health of astronauts.

Stroke specialists raise another $50M thanks to late investment from Novo Holdings

California-based Route 92 Medical previously announced a funding round worth more than $31 million in November. Now, however, a massive addition from Novo Holdings makes the round worth closer to $82 million. 

A majority of medical devices involved in Class I recalls were never required by the U.S. Food and Drug Administration (FDA) to undergo premarket or postmarket clinical testing, according to new research published in Annals of Internal Medicine.[1]

Most recalled cardiovascular devices gained FDA approval with little to no clinical evidence

Why are so many cardiovascular devices involved in Class I recalls? One possible reason could be the large number of devices hitting the market without undergoing much premarket clinical testing. 

Researchers have found that homemade play-putty can effectively capture electrocardiogram (ECG) signals at a level comparable to commercially available electrodes. The play-putty is made with a simple mix of flour, water, salt, cream of tartar and vegetable oil—but the potential is much more than one may expect.

Homemade electrodes made of putty capture heart data as well as some commercial devices

The putty, made with basic ingredients found around the house, can effectively capture ECG measurements.
