Seniors With Insufficient Levels Of Vitamin D At Increased Risk Of Dying From Heart Disease - 0 views

  •  
    A new study by researchers at the University of Colorado Denver and Massachusetts General Hospital (MGH) shows vitamin D plays a vital role in reducing the risk of death associated with older age. The research, just published in the Journal of the American Geriatrics Society, evaluated the association between vitamin D levels in the blood and the death rates of those 65 and older. The study found that older adults with insufficient levels of vitamin D die from heart disease at greater rates that those with adequate levels of the vitamin.

Smoking trumps omega-3s to drive up atherosclerosis rates in Alaskan Eskimos - theheart.org - 0 views

  •  
    "July 10, 2008 | Shelley Wood New York, NY - Despite eating a diet rich in omega-3 fatty acids, Alaskan Eskimo are developing subclinical atherosclerosis at an early age, likely due in large part to heavy smoking, a new study shows [1]. According to investigators, in a paper published online July 10, 2008 in Stroke, rates of carotid atherosclerosis in the mostly young to middle-aged subjects participating in the Genetics of Coronary Artery Disease in Alaska Natives (GOCADAN) study were significantly higher than those reported in US population-based studies of other ethnic groups. But as Dr Alexis Cutchins (Weill Cornell Medical College, New York, NY) and colleagues report, rates of current smoking among the Eskimo population studied were also four to six times higher than that of other US populations in similar studies. "I don't think there's anything very surprising here, but I guess what is novel is that the findings relate to a population that has not been studied much, if at all, in this regard," study coauthor Dr Mary J Roman (Weill Cornell Medical College) told heartwire. "And I think that the message is one that has public-health implications for everybody else: this is basically a reiteration of the fact that smoking is a very potent cardiovascular risk factor, and I think the indoctrination that most of us have received about the ills of smoking have clearly not penetrated the Alaska Eskimo population.""

Effects Of Vitamin D Deficiency Amplified By Shortage Of Estrogen - 0 views

  •  
    "Researchers at Johns Hopkins are reporting what is believed to be the first conclusive evidence in men that the long-term ill effects of vitamin D deficiency are amplified by lower levels of the key sex hormone estrogen, but not testosterone. In a national study in 1010 men, to be presented Nov. 15 at the American Heart Association's (AHA) annual Scientific Sessions in Orlando, researchers say the new findings build on previous studies showing that deficiencies in vitamin D and low levels of estrogen, found naturally in differing amounts in men and women, were independent risk factors for hardened and narrowed arteries and weakened bones. Vitamin D is an essential part to keeping the body healthy, and can be obtained from fortified foods, such as milk and cereals, and by exposure to sunlight.

Vitamin D Deficiency Lead to Disease - Dr. Weil's Weekly Bulletin - 0 views

  •  
    "If you're running low on vitamin D - as an estimated 70 percent of the U.S. population is - your immune system may not be functioning as well as it should. As a result, you may be more vulnerable to infectious diseases than you would if your vitamin D levels were optimal. Worse, you could be at higher than normal risk of a long list of diseases including heart disease and several kinds of cancer. A report recently published journal, Future Microbiology, highlighted research at the Linus Pauling Institute at Oregon State University, which has shown that vitamin D induces expression of an antimicrobial peptide gene called cathelicidin that is the "first line of defense" in the immune system's response to minor wounds, cuts and bacterial and viral infections. The regulation of cathelicidin by vitamin D could help explain its vital role in immune function. The report noted that vitamin D is a key cofactor in reducing inflammation, in blood pressure control and helping to protect against heart disease. Author Adrian Gombart explains that there is still much to explore about D's mechanisms of action, the potential use of synthetic analogs of it in new treatments, and its duty in fighting infection."

Vegetables, Nuts And Mediterranean Diet Better For Heart, Research Review - 0 views

  •  
    Scientists in Canada reviewing the research so far on links between different diets and heart disease found strong evidence that diets high in vegetables and nuts, and those that follow a Mediterranean pattern rich in fruit, vegetables and fish were strongly associated with lower heart disease risk than those that rely on food with a high glycemic index or high in trans-fatty acids. High glycemic index food includes rice, pasta and refined carbohydrates like white bread, and foods high in trans-fatty acids include fried foods, baked goods and snacks.

JUPITER: Low LDL and low CRP best for reducing events in primary prevention - theheart.org - 0 views

  •  
    "March 29, 2009 | Michael O'Riordan Orlando, FL - Reducing LDL cholesterol and high-sensitivity C-reactive protein (hs-CRP) in primary-prevention patients treated with rosuvastatin (Crestor, AstraZeneca) results in better event-free survival than when neither of these targets are achieved or when LDL cholesterol alone is reduced, a new analysis shows [1]. Presenting the results of the Justification for the Use of Statins in Primary Prevention: An Intervention Trial Evaluating Rosuvastatin (JUPITER) study during an afternoon press conference at the American College of Cardiology 2009 Scientific Sessions, investigators say that initial interventions for low-risk primary-prevention patients remains lifestyle and dietary modifications, but for those choosing drug therapy, "reductions in both LDL cholesterol and hs-CRP are indicators of the success of treatment with statin therapy.""

Vitamin D: A potential role in cardiovascular disease prevention - theheart.org - 0 views

  •  
    "November 24, 2009 | Lisa Nainggolan Orlando, FL - Inadequate levels of vitamin D are associated with an increase in the risk of cardiovascular disease and death, a new observational study has found. Dr Tami L Bair (Intermountain Medical Center, Murray, UT) reported the findings here at the American Heart Association 2009 Scientific Sessions. Bair and colleagues followed more than 27 000 people 50 years or older with no history of cardiovascular disease for just over a year and found that those with very low levels of vitamin D (30 ng/mL). Those deficient in vitamin D were also twice as likely to develop heart failure as those with normal levels. "We concluded that even a moderate deficiency of vitamin D was associated with developing coronary artery disease, heart failure, stroke, and death," said coauthor Dr Heidi May (Intermountain Medical Center). However, "it is not known whether this is a cause and effect relationship," she told heartwire. Because this study was observational, more research is needed "to better establish the association between vitamin D deficiency and cardiovascular disease," she noted."

Does Eating Fewer Calories Improve the Brain?: Scientific American - 0 views

  •  
    Hara hatchi bu, the Okinawan people's habit of eating only till they are 80 percent full, is thought to be one of the secrets of their extraordinary health and longevity. In addition to one of the highest percentages of people in the world who live past 100, Okinawans appear to be less prone to heart disease, diabetes and obesity. Indeed, ever since it was discovered in the 1930s that laboratory rats fed a caloric-restricted (CR) diet lived almost twice as long as their well fed counterparts, scientists have pursued caloric restriction research in the hopes of finding novel strategies for extending human life and preventing disease. Given the growing older population at risk for memory problems and the rising rates of obesity, the role of diet in maintaining peak brain performance has taken on added importance.

Japan EPA Lipid Intervention Study (JELIS) - Дискуссионный Клуб Русского Медицинского Сервера - 0 views

  •  
    "18 645 patients with a total cholesterol of 6·5 mmol/L or greater were recruited from local physicians throughout Japan between 1996 and 1999. Patients were randomly assigned to receive either 1800 mg of EPA daily with statin (EPA group; n=9326) or statin only (controls; n=9319) with a 5-year follow-up. The primary endpoint was any major coronary event, including sudden cardiac death, fatal and non-fatal myocardial infarction, and other non-fatal events including unstable angina pectoris, angioplasty, stenting, or coronary artery bypass grafting. Analysis was by intention-to-treat. Findings At mean follow-up of 4·6 years, we detected the primary endpoint in 262 (2·8%) patients in the EPA group and 324 (3·5%) in controls-a 19% relative reduction in major coronary events (p=0·011). Post-treatment LDL cholesterol concentrations decreased 25%, from 4·7 mmol/L in both groups. Serum LDL cholesterol was not a significant factor in a reduction of risk for major coronary events. Unstable angina and non-fatal coronary events were also significantly reduced in the EPA group. Sudden cardiac death and coronary death did not differ between groups. In patients with a history of coronary artery disease who were given EPA treatment, major coronary events were reduced by 19% (secondary prevention subgroup: 158 [8·7%] in the EPA group vs 197 [10·7%] in the control group; p=0·048). In patients with no history of coronary artery disease, EPA treatment reduced major coronary events by 18%, but this finding was not significant (104 [1·4%] in the EPA group vs 127 [1·7%] in the control group; p=0·132)."

Medical News: AHA: Trans Fats Raise Cholesterol Regardless of Source - in Meeting Coverage, AHA from MedPage Today - 1 views

  •  
    NEW ORLEANS, Nov. 10 -- Gram for gram, trans fatty acid from milk and meat may be as bad for the heart as it is from processed foods, Dutch researchers found. In a randomized trial, a diet containing a high quantity of trans fats significantly increased cholesterol levels across the board whether from natural or "industrial" sources (P=0.014 to P<0.001), Ingeborg A. Brouwer, Ph.D., of VU University Amsterdam, and colleagues reported here at the American Heart Association meeting.
