The study analyzed the results of eight major research trials involving nearly 20,000 patients who underwent interventional heart procedures, such as balloon angioplasty or stent placement. Patients with peripheral arterial disease (PAD), which mainly includes blockages in leg arteries, were found to be more than twice as likely to die within a week after interventional heart procedures compared with patients free of PAD.
This doubling in mortality rates persisted at 30-day and later follow-up. At one year following the heart procedure, 5 percent of patients with PAD had died versus 2.1 percent of patients without PAD. However, while nearly half of Americans 65 or older are expected to have the condition by 2050, only a quarter of PAD patients presently receive treatment. Further, patients with PAD undergoing heart interventions were also more at risk for other complications, including blood clots and bleeding requiring a transfusion.
The study was authored by 13 internationally recognized cardiology researchers, including Dr. David J. Moliterno, Gill Heart Institute medical director and professor and chief of cardiovascular medicine in the UK College of Medicine Department of Internal Medicine, and Dr. Steven R. Steinhubl, associate professor and director of cardiovascular education and clinical research at UK.
"Peripheral arterial disease is prevalent in Kentucky and throughout much of the United States, yet it is strikingly under diagnosed and certainly under treated. It is undeniably easy to ask patients if their legs cramp when they walk, and if so to take a blood pressure recording in not only their arms but also their legs. These steps could be life-saving," Moliterno said.
While the study does not indicate that patients with PAD should avoid interventional procedures, it is a strong reminder that extra precaution should be taken when treating these patients.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
