Coronary artery disease (CAD) is prevalent in patients with PAD and it is known that PAD is under diagnosed in the primary care setting, but a new study found that it is often overlooked even in patients with known heart disease who are under a cardiologist’s care. The study was published in the May issue of Catheterization and Cardiovascular Interventions, the official journal of The Society for Cardiovascular Angiography and Interventions (SCAI).
Led by Dr. Issam D. Moussa of New York Presbyterian Hospital/Weill Cornell Medical Center, the study involved nearly 800 patients with ischemic heart disease who were to undergo coronary angiography and/or intervention and were either at least 70 years old, or between the ages of 50 and 69 and had a history of diabetes mellitus and/or tobacco use. Researchers determined if patients had PAD by calculating the Ankle-Brachial Index, the ratio of the blood pressure in the lower legs to blood pressure in the arms, which is normally the first test administered to patients in cases where PAD is suspected. Patients also answered questionnaires on PAD awareness and functional status.
The results showed that approximately one out of six patients had previously unrecognized PAD, despite being under the care of a cardiovascular specialist. The researchers point out that this includes only those with previously undiagnosed PAD and does not represent the total prevalence of PAD in patients with heart disease, which is actually much higher. Most patients with PAD did not limp or have leg pain, two symptoms of the disease. “The combination of physician lack of awareness and lack of symptoms among patients results in failure to diagnose PAD, even in patients who are at high risk,” the researchers state. “Furthermore, clinical evaluation alone often lacks the sensitivity and specificity to optimally identify PAD particularly in less advanced stages and in hospitalized patients with CAD.”
The study also found that previously missed PAD was more frequent in older patients and women, which goes against the conventional wisdom that PAD is more prevalent in men and suggests that PAD is more frequently overlooked in women than men in outpatient settings. In addition, the study showed that patients with PAD had a more severe form of CAD, which may account for the worse outcome of heart patients who also have PAD compared to those who do not. The authors note that “making a diagnosis of PAD in a patient with CAD should prompt the clinician to be more aggressive with risk factor intervention, foot protection and a high clinical index of suspicion for progressive PAD symptoms,” adding that these patients should be viewed as exceptionally high risk.
They also note that establishing an early diagnosis of PAD promotes the preservation of functional status in the lower limbs, which is particularly important in patients CAD, since PAD may limit active participation in cardiovascular rehabilitation following coronary interventions. Many physicians cite the lack of space, time and resources as barriers to implementing a systematic PAD screening program, however new guidelines by the American Heart Association and the American College of Cardiology advocate screening for PAD in patients with CAD. The authors conclude that their findings present a compelling argument that screening for PAD should become standard of care in these patients.

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
