Bariatric Surgery Linked to Reduced Risk of Cardiovascular Death

1 Mins read

In the January 4, 2012, edition of JAMA, researchers at the University of Gothenburg in Sweden determined that bariatric surgery is associated with reduced risk of cardiovascular deaths and events such as heart attack and stroke in obese individuals.  As the researchers note, “this is the first prospective, controlled intervention to our knowledge reporting that bariatric surgery is associated with reduced incidence of cardiovascular deaths and cardiovascular events.”

In the January 4, 2012, edition of JAMA, researchers at the University of Gothenburg in Sweden determined that bariatric surgery is associated with reduced risk of cardiovascular deaths and events such as heart attack and stroke in obese individuals.  As the researchers note, “this is the first prospective, controlled intervention to our knowledge reporting that bariatric surgery is associated with reduced incidence of cardiovascular deaths and cardiovascular events.”

The correlation between obesity and the presence of “co-morbidities” such as type 2 diabetes, hypertension and other conditions has been supported by clinical data, there has been a notable absence of direct data on the association between bariatric surgery and improvements in overall health that reduce the risk of death.  The Gothenburg study confirmed this specifically by studying 2,010 obese patients who underwent bariatric surgery contrasted to a control group of 2,037 obese individuals receiving standard care.

The authors were careful to note that the reduction in risk only correlated with modest weight loss from bariatric surgery and that subsequent, greater weight loss did not further reduce risk.  The authors also note that additional research is needed on any possible correlation between weight loss other than by bariatric surgery and reduction in risk of death.

Below is illustrated the market for various obesity treatment options, with expected product revenues in 2013 and growth to 2019.

About author
I serve the interests of medical technology company decision-makers, venture-capitalists, and others with interests in medtech producing worldwide analyses of medical technology markets for my audience of mostly medical technology companies (but also rapidly growing audience of biotech, VC, and other healthcare decision-makers). I have a small staff and go to my industry insiders (or find new ones as needed) to produce detailed, reality-grounded analyses of current and potential markets and opportunities. I am principally interested in those core clinical applications served by medical devices, which are expanding to include biomaterials, drug-device hybrids and other non-device technologies either competing head-on with devices or being integrated with devices in product development. The effort and pain of making every analysis global in scope is rewarded by my audience's loyalty, since in the vast majority of cases they too have global scope in their businesses. Specialties: Business analysis through syndicated reports, and select custom engagements, on medical technology applications and markets in general/abdominal/thoracic surgery, interventional cardiology, cardiothoracic surgery, patient monitoring/management, wound management, cell therapy, tissue engineering, gene therapy, nanotechnology, and others.
