Under-Recognized Condition Important In Treatment of High Blood Pressure

31.08.2004


An under-recognized and usually asymptomatic condition called subclavian artery stenosis – an obstruction of arteries located under the clavicle, or collarbone – is important in the diagnosis and treatment of high blood pressure, according to a study by researchers at the University of California, San Diego (UCSD) School of Medicine and Northwestern University’s Feinberg School of Medicine in Chicago.



Published in the August 4, 2004 issue of the Journal of the American College of Cardiology, the study investigated the prevalence of subclavian artery stenosis (SS) in 4,223 individuals, and determined risk factors.

SS was found in approximately 2 percent of individuals without cardiovascular problems and in 7 percent of those currently under a doctor’s care for cardiovascular conditions. Patients most at risk were those with current or past smoking histories, higher than normal systolic blood pressure, lower levels of HDL cholesterol, and the presence of peripheral arterial disease (PAD), which is characterized by narrowing of the arteries in the legs and arms due to build-up of atherosclerotic plaque on vessel walls. Patients with PAD were found to be at a fivefold greater risk of having SS.


Michael H. Criqui, M.D., M.P.H., UCSD School of Medicine professor of family and preventive medicine and one of the study’s primary authors, noted that bilateral arm blood pressure measurements should routinely be performed in patients with an elevated risk profile, both to screen for SS and to avoid missing a hypertension or PAD diagnosis. A PAD diagnosis is made using blood pressure measurements from both the arm and the ankle.

In addition to Criqui, the study included first author Ramin Shadman, B.A., a fourth year UCSD medical student; Mary M. McDermott, M.D., Feinberg School of Medicine, Northwestern University; Warner P. Bundens, M.D. and Arnost Fronek, M.D., UCSD Department of Surgery; and Julie O. Denenberg, M.A. and Anthony C. Gamst, Ph.D., UCSD Department of Family and Preventive Medicine. The study was funded by the National Institutes of Health, and the UCSD Stein Institute for Research on Aging.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
