MONDAY, Feb. 14 (HealthDay News) -- Obese men grappling a dramatically higher venture of dying from a hunch attack, regardless of whether or not they hit added known venture factors for cardiovascular disease, a newborn think reveals.

The uncovering stems from an analysis involving roughly 6,000 middle-aged men, and it suggests that there is something most carrying around immoderateness weight that contributes to hunch disease independent of venture factors much as broad murder pressure, diabetes, broad cholesterin and arterial disease.

What just that something is, however, relic unclear, although the researchers suggest that the chronic inflammation that typically accompanies momentous coefficient gain strength be the dynamical obligate behindhand the increased risk.

"Obese, middle-aged men hit a 60 proportionality accumulated venture of dying from a hunch move than non-obese middle-aged men, modify after we cancel out any of the personalty of cholesterol, murder push and added cardiovascular risk factors," noted think communicator Jennifer Logue, a clinical pedagogue of metabolic penalization with the British Heart Foundation's Cardiovascular Research Centre at the University of Glasgow, in Scotland. "This effectuation [that] blubber itself haw be causing mortal hunch attacks through a bourgeois that we hit not ease identified."

Logue and her colleagues report their observations in the Feb. 15 online supply of Heart.

To explore the subject, the authors spent nearly 15 eld tracking 6,082 male patients who were diagnosed with broad cholesterin but had no history of either hunch disease or diabetes.

Over the think period, the investigate aggroup noted 214 hunch disease fatalities, along with added 1,027 hunch attacks and/or strokes that did not termination in death.

The aggroup confirmed the well-established theory that existence fat is linked to a greater quantity for having every of the classic venture factors linked to hunch disease.

That said, modify after judgement out germane variables much as age and smoking history, the venture of modification among fat men -- those with a embody mass index (BMI) between 30 and 39.9 -- was ease 75 proportionality higher than it was for non-obese men.

What's more, modify after also accounting for venture factors much as broad blood push and diabetes (as substantially as medication history), the quantity of experiencing a mortal hunch move was 60 proportionality greater among fat men, as compared with non-obese men.

The digit caveat: in and of itself, existence fat was not linked to a higher venture of experiencing a non-fatal hunch move or stroke.

Logue cautioned that boost investigate is needed to support the findings, and to uncover the literal execution by which blubber itself is a risk bourgeois for mortal hunch attacks.

"Possible reasons include portion chemicals that the fat cells are releasing. Or perhaps it is attendant to the fact that fat people run to have large whist to control with the additional stress of their large size, and this already heavy hunch does not control to move to work during a hunch attack," she said.

"However, it certainly makes me think that we cannot just treat cholesterol, murder push and diabetes in fat men without also considering their weight," Logue added. "We requirement to encounter easier and more effective ways to support people retrograde coefficient and encounter out if losing coefficient can support turn the venture of mortal hunch attacks. We also requirement to dedicate far more resources to preventing blubber in the first place."

Dr. Gregg C. Fonarow, a academic of cardiology at the University of California, Los Angeles, said that the current think "provides boost evidence as to why there needs to be global efforts to preclude and treat obesity though lifestyle modification."

"While blubber is related with elevations in murder pressure, increased venture of diabetes and deviant glyceride levels, it has been inferior clear whether the accumulated venture of mortality related with blubber can be entirely explained by these well-established cardiovascular venture factors or whether added factors attendant to blubber haw also be contributing to immoderateness mortality risk," he noted.

Dr. Murray A. Mittleman, director of the Cardiovascular Epidemiology Research Unit with the Beth Israel Deaconess Medical Center, Harvard Medical School in Boston, agreed.

"It's not astonishing that not every of the venture can be explained by traditional venture factors," he said. "But no digit think is going to definitively answer the question as to what added mechanisms for venture might be. So the primary supply would ease move to be employed towards overall coefficient reduction, to turn the venture for every of the pathways that we already undergo go along with obesity."
