American Heart Association reports Clinic Readings may underestimate Blood Pressure during Daily Activities
December 6, 2016
American Heart Association Rapid Access Journal Report
Dallas, TX – Around the clock monitoring during daily activity revealed masked, or undetected, high blood pressure among otherwise healthy adults who had normal readings in the clinic, according to new research in the American Heart Association’s journal Circulation.
The reverse of “white coat hypertension” (higher blood pressure readings at the doctor’s office than outside the clinic setting), “masked hypertension” is normal blood pressure in the doctor’s office but high readings outside of the office.
Healthcare providers should be aware that normal blood-pressure tests in the clinic may not rule out high blood pressure among otherwise healthy patients. (American Heart Association)
Technique to stimulate heart cells may lead to light-controlled Pacemakers
August 12, 2011
Dallas, TX – A new technique that stimulates heart muscle cells with low-energy light raises the possibility of a future light-controlled pacemaker, researchers reported in Circulation: Arrhythmia & Electrophysiology, a journal of the American Heart Association.
“Electronic cardiac pacemakers and defibrillators are well established and successful technologies, but they are not without problems, including the breakage of metal leads, limited battery life and interference from strong magnetic fields,” said Emilia Entcheva, Ph.D., senior author of the study and associate professor of biomedical engineering at Stony Brook University in Stony Brook, New York. “Eventually, optical stimulation may overcome some of these problems and offer a new way of controlling heart function.” [Read more]
