Obesity strongly linked to pulmonary embolism and deep venous thrombosis

12.09.2005


Since 1927, obesity has been thought to be a risk factor for fatal pulmonary embolism (PE). Because of the high proportion of obesity in the general population, previous studies have not determined whether obesity is an independent risk factor for PE or deep venous thrombosis (DVT). In an extensive study published in the September issue of The American Journal of Medicine, researchers from St. Joseph Mercy Oakland Hospital, Pontiac, Michigan; Wayne State University, Detroit, Michigan; and Oakland University, Rochester, Michigan; analyzed over 20 years of patient records compiled by the National Hospital Discharge Survey (NHDS) to further investigate the potential risk of obesity in venous thromboembolism. The investigators concluded that obesity is a risk factor for venous thromboembolic disease in men as well as women, particularly those under age 40.



The NHDS is comprehensive in its scope including data on patients of all races and ages obtained annually from 181,000 to 307,000 sampled patient abstracts from 400 to 494 non-Federal short-stay hospitals in 50 states and the District of Columbia. There were more than 12,000,000 obese patients and almost 700,000,000 non-obese patients in the sampled data.

The relative risk of DVT, comparing obese patients with non-obese patients, was 2.50. The relative risk of PE was 2.21. Obese females had a greater relative risk for DVT than obese males, 2.75 versus 2.02. Obesity had the greatest impact on patients aged less than 40 years, in whom the relative risk for PE in obese patients was 5.19 and the relative risk for DVT was 5.20. In females aged less than 40 years, the relative risk for DVT comparing obese with non-obese patients was 6.10. In males less than 40 years of age, the relative risk for DVT was 3.71.


Paul D. Stein, MD, writes "Now that we know with certainty that obesity is a risk factor for PE, particularly in men and women under age 40, the presence of obesity may alert physicians to a possibility of the diagnosis. The diagnosis of PE is frequently missed even though PE is the third most common acute cardiovascular disease after myocardial infarction and stroke."

Im Focus: Data storage using individual molecules

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.

Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: An energy-efficient way to stay warm: Sew high-tech heating patches to your clothes

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
