New methods needed to ID cardiac catheterization candidatesIt is to reconsider time, as patients are selected for cardiac catheterization, say doctors at Duke University Medical Center, according to the report in a new study that the invasive procedure found no significant coronary artery disease in nearly 60 % of chest pain patients without heart disease. Our data show that up to two thirds of patients invasive coronary angiography are found no significant obstructive disease have , Manesh Patel, a cardiologist says the Duke Heart Center . He is the main author of the study, the 11th – Released March edition of the New England Journal of Medicine. – We spend a lot of energy and money to breast pain, often leading to a cardiac catheterization, now now is, often, the patient noted no significant obstructive disease, says Patel. Our research shows that our methods for identifying patients at risk for obstructive disease need significant improvement. Four year More than 10 million Americans experience chest pain each year and many undergo as cardiac catheterization to determine whether test blocked arteries of the perpetrators , it is standard care for a heart attack or a heart attack or unstable chest pain Invasive test is not cheap, it is not risk risk, but it allows doctors the vessels and arteries to visualize the heart. The researchers identified two million people the cardiac catheterization at 663 hospitals underwent nationwide over a four-year period. About one fifth of patients had stable chest pain without prior diagnosis of heart disease, most of them a noninvasive a noninvasive test before catheterization, to the role. Percent of patients proved to have significant obstructive disease.

Mouse is used. Out The Jet Lag Jet LagEveryone hates to the jetlag – the nocturnal wakefulness, loss of appetite, decreased alertness, and depressed mood – the accompanied Get to places across different time zones. The symptoms of on jetlagged carried shift from of a person internal clock and exterior causes times. Gregor Eichele and its colleagues at the Max Planck Institute for Biophysical Chemistry, Germany, new insights in the molecular mechanisms involved provided for resetting the the internal the circadian system in to the mouse is used. One of their key observations shows that modulation speed at which that the adrenal gland his rhythmic output on glucocorticoid hormones with the new light / dark cycle governs resetting the whole interior body clock. The authors believe that its data suggest new potential treatment at overcome jet lag.
