Severe sepsis, new-onset AF associated with increased risk of hospital stroke, death

14.11.2011
A recent study led by researchers at Boston University School of Medicine (BUSM) shows an increased risk of stroke and mortality among patients diagnosed with severe sepsis and new-onset atrial fibrillation (AF) during hospitalization.

Allan J. Walkey, MD, assistant professor of medicine at BUSM and a pulmonologist at Boston Medical Center (BMC), is the lead author of the study, which will be published in the Journal of the American Medical Association. Walkey also will present the findings at the American Heart Association's annual Scientific Sessions in Orlando, Fla., on Sunday, Nov. 13, at 4:45 p.m. ET.

Severe sepsis is the 10th leading cause of death in the United States, and atrial fibrillation affects one in four people over the age of 40. While both are common illnesses, and chronic atrial fibrillation is a known risk factor for stroke and death, very little is known about new-onset atrial fibrillation during severe sepsis.

"The purpose of our retrospective study was to examine if a new-onset atrial fibrillation diagnosis in patients with severe sepsis was associated with an increased the risk of stroke and mortality in a hospital setting," said Walkey.

The researchers examined data, provided by the Agency for Healthcare Research and Quality, from more than three million hospitalized patients. Looking at the risks of stroke and mortality, patients with new- onset atrial fibrillation during severe sepsis had three times the risk of having a stroke and a seven percent increased risk of death during hospitalization. Almost three percent of patients with new-onset atrial fibrillation during severe sepsis had a stroke during hospitalization compared to less than one percent of those not diagnosed with the condition during severe sepsis.

The data also showed that 56 percent of patients with severe sepsis and new-onset atrial fibrillation died, whereas 39 percent of patients with severe sepsis who did not develop new-onset atrial fibrillation did not. Additionally, six percent of patients with severe sepsis developed new-onset atrial fibrillation compared to less than one percent of patients who did not have severe sepsis and were hospitalized for another reason. Furthermore, among all patients with or without severe sepsis, 14 percent of all new-onset atrial fibrillation cases occurred in patients with severe sepsis.

"It is projected that one million Americans will have severe sepsis this year, and based on our data, approximately 60,000 people will develop new-onset atrial fibrillation," said Walkey. "There are currently no guidelines on how best to care for these specific patients, but this study is a call to action that this under-recognized potential complication of severe sepsis requires further investigation on how to treat these critically ill patients."

This research was funded by that National Institutes of Health's National Heart Lung and Blood Institute.

About Boston University School of Medicine

Originally established in 1848 as the New England Female Medical College, and incorporated into Boston University in 1873, Boston University School of Medicine today is a leading academic medical center with an enrollment of more than 700 medical students and more than 800 masters and PhD students. Its 1,246 full and part-time faculty members generated more than $335 million in funding in the 2009-2010 academic year for research in amyloidosis, arthritis, cardiovascular disease, cancer, infectious disease, pulmonary disease and dermatology among others. The School is affiliated with Boston Medical Center, its principal teaching hospital, the Boston and Bedford Veterans Administration Medical Centers and 16 other regional hospitals as well as the Boston HealthNet.

Im Focus: Optical Nanoscope Allows Imaging of Quantum Dots

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.

Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
