TUESDAY, Jan. 9, 2018 -- High doses of vitamin D seem to keep arteries more flexible and pliable, potentially warding off future heart disease, heart attacks and strokes, preliminary research suggests.
In just four months, vitamin D supplements reduced arterial stiffness in a group of 70 young black men and women, according to results from a small-scale clinical trial.
WEDNESDAY, Dec. 27, 2017 -- Powerful magnetic fields created during an MRI scan were thought to play havoc with some pacemakers, but a new study says these scans are safe for people with the heart devices.
Researchers tested the safety of MRIs on more than 1,500 people who had older pacemakers or implantable defibrillators -- called legacy devices -- that the U.S. Food and Drug Administration does not consider safe for MRIs. The result: No long-term adverse effects were found.
