New approach for assessing and managing patients with sepsis

Each year over a million people suffer from sepsis, a condition caused by an infection spreading through the body. If sepsis develops into severe sepsis then the death rate can rise to nearly 30 - 50%, equalling the number of deaths caused by a heart attack.

New perspective on coronary disease thanks to ultrasound

Compared to other techniques, Intravascular Ultrasound (IVUS) is much better at monitoring the increase or decrease of atherosclerosis in the coronary arteries. Can the method even be used to predict the odds of a heart attack or other cardiovascular event? Studies indicate this may be the case, states Professor Clemens von Birgelen in his inaugural address at the University of Twente.
