Alternative News:

  • Vitamin D Status at ICU Admission May Predict A-Fib and Bedsores - Medscape, 2/28/17 - "Patients with Vitamin D levels below 20 ng/mL were nearly four times as likely to develop new-onset atrial fibrillation, with an odds ratio of 3.59 (95% CI, 1.01–12.70). On regression analysis, the risk for the condition decreased by 15% for each unit increase in vitamin D ... A second study of 402 surgical ICU patients found that 11 percent developed hospital-acquired pressure ulcers. Patients with vitamin D levels below 20 ng/mL were more than twice as likely to develop the ulcers (OR 2.51; 95% CI, 1.06–5.97). On regression analysis, the risk of ulcers fell by 11% with each unit increase in vitamin D" - See vitamin D at Amazon.com.
  • Vitamin C may decrease risk of atrial fibrillation after cardiac surgery - Science Daily, 2/1/17 - "The single study on the recurrence of AF after a successful cardioversion, which was carried out in Greece, found that vitamin C decreased the risk of AF recurrence by 87% ... In the non-US cardiac surgery trials, vitamin C decreased the length of hospital stay by 12.6% and intensive care unit stay by 8.0% ... Oral administration of vitamin C decreased the occurrence of post-operative AF by 73%, whereas intravenous administration decreased it by 36%. On the other hand, oral administration shortened the length of hospital stay by only 7% (0.4 days), whereas intravenous administration decreased it by 16% (1.5 days). Thus, the effect of intravenous vitamin C administration was greater for the length of hospital stay, but less for the occurrence of post-operative AF" - See American Health Products - Ester C W/Citrus Bioflavonoids, 1000 mg, 180 veg tablets at Amazon.com.
  • Metformin and Lower AF Risk Among Patients With T2DM - Medscape, 10/13/14 - "After adjusting for co-morbidities and medications, metformin independently protected the diabetic patients from new-onset AF with a hazard ratio of .81 (95% confidence interval 0.76–0.86, p < 0.0001). Metformin significantly decreased the extent of pacing-induced myolysis and the production of reactive oxygen species" - [Abstract] - See metformin at IAS.
  • U-shaped curve revealed for association between fish consumption and atrial fibrillation - Science Daily, 6/24/13 - "The study found a U-shaped association between consumption of marine n-3 polyunsaturated fatty acids (n-3 PUFA) and the risk of developing AF, with people who have both low and high intakes found to suffer more from AF than those with median intakes. The lowest risk of AF was found in those who consumed around 0.63 g marine n-3 PUFA per day, which corresponds to around two servings of fatty (oily) fish per week ... Earlier studies have reported that regular consumption of fish can exert beneficial effects in preventing the development of AF. Notably, in the Cardiovascular Health study², which included 4,815 participants, a 28% lower risk of AF was observed among people who consumed fish one to four times per week compared with those who ate fish less than once per month. However, such observed associations have not been confirmed in all cohort studies"
  • CKD and Low Magnesium: Pay Attention - Medscape, 2/6/13 - "When adjusted for differences in age and sex among quartiles, the lowest magnesium group had the highest incidence of new atrial fibrillation events (9.4 episodes per 1000 person-years). The rates for the other 3 quartiles were quite similar (6.9, 7.1, and 6.3 events per 1000 person-years for the second, third, and fourth quartiles, respectively). In multivariable models controlled for the multiple potential differences including glomerular filtration rate, those with the lowest levels of magnesium continued to be at highest risk for the development of atrial fibrillation (hazard ratio, 1.48; 95% confidence interval, 1.02- 2.14; P = .04)" - See magnesium supplements at Amazon.com.
  • Low Serum Magnesium and the Development of Atrial Fibrillation in the Community: The Framingham Heart Study - Circulation. 2012 Nov 21 - "We studied 3,530 participants (mean age, 44 years; 52% women) from the Framingham Offspring Study who attended a routine examination, and were free of AF and cardiovascular disease ... 20 years of follow-up ... The age- and sex-adjusted incidence rate of AF was 9.4 per 1,000 person-years (95% confidence interval, 6.7 to 11.9) in the lowest quartile of serum magnesium (≤1.77 mg/dl), compared with 6.3 per 1,000 person-years (95% confidence interval, 4.1 to 8.4) in the highest quartile (≥1.99 mg/dl). In multivariable-adjusted models, individuals in the lowest quartile of serum magnesium were approximately 50% more likely to develop AF (adjusted hazard ratio, 1.52, 1.00 to 2.31; P=0.05), compared with those in the upper quartiles ... Because hypomagnesemia is common in the general population, a link with AF may have potential clinical implications" - See Jarrow Formulas, Magnesium Optimizer Citrate, 100 Easy-Solv Tablets at iHerb.
  • Association of Plasma Phospholipid Long-Chain Omega-3 Fatty Acids with Incident Atrial Fibrillation in Older Adults: The Cardiovascular Health Study - Circulation. 2012 Jan 26 - "In multivariable Cox models adjusted for other risk factors, the RR in the top versus lowest quartile of total n-3 PUFA (EPA+DPA+DHA) levels was 0.71 (95%CI=0.57-0.89, P-trend=0.004); and of DHA levels, 0.77 (95%CI=0.62-0.96, P-trend=0.01). EPA and DPA levels were not significantly associated with incident AF. Evaluated non-parametrically, both total n-3 PUFA and DHA showed graded and linear inverse associations with incidence of AF" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.
  • Effect of Dietary Fish Oil on Atrial Fibrillation After Cardiac Surgery - Am J Cardiol. 2011 Jul 13 - "Two hundred patients were randomized to receive fish oil (providing 4.6 g/day of long-chain ω-3 fatty acids) or a control oil starting 3 weeks before surgery; 194 subjects completed the study, with 47 of 97 subjects in the control group and 36 of 97 subjects in the fish oil group developing AF (odds ratio 0.63, 95% confidence interval [CI] 0.35 to 1.11). There was a nonstatistically significant delay in time to onset of AF in the fish oil group (hazard ratio 0.66, 95% CI 0.43 to 1.01). There was a significant decrease in mean length of stay in the intensive care unit in the fish oil group (ratio of means 0.71, 95% CI 0.56 to 0.90). In conclusion, in a mixed cardiac surgery population, supplementation with dietary fish oil did not result in a significant decrease in the incidence of postsurgical AF. However, there was a significant decrease in time spent in the intensive care unit" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.
  • Slowing a Speedy Heart Rate? - Dr. Weil, 4/29/10
  • Influence of coffee and caffeine consumption on atrial fibrillation in hypertensive patients - Nutr Metab Cardiovasc Dis. 2010 Feb 16 - "Coffee and caffeine consumption influence spontaneous conversion of atrial fibrillation. Normotensive non-habitual coffee consumers are more likely to convert arrhythmia within 48h from the onset of symptoms. Hypertensive patients showed a U-shaped relationship between coffee consumption and spontaneous conversion of AF, moderate coffee consumers were less likely to show spontaneous conversion of arrhythmia. Patients with left ventricular hypertrophy showed a reduced rate of spontaneous conversion of arrhythmia"
  • Omega-3 fatty acid supplementation reduces one-year risk of atrial fibrillation in patients hospitalized with myocardial infarction - Eur J Clin Pharmacol. 2008 Feb 29 - "N-3 PUFA reduced the relative risk of the hospitalization for AF [hazard ratio (HR) 0.19, 95% CI 0.07-0.51] and was associated with a further and complementary reduction in all-cause mortality (HR 0.15, 95% CI 0.05-0.46)" - See Mega Twin EPA at Amazon.com.
  • N-acetylcysteine for the prevention of postoperative atrial fibrillation: a prospective, randomized, placebo-controlled pilot study - Eur Heart J. 2008 Feb 8 - "The result of this study indicates that NAC treatment decreases the incidence of postoperative AF" - See n-acetyl cysteine at Amazon.com.
  • Recurrence of Atrial Fibrillation Reduced With Alpha-Linolenic Acid-Enriched Diet - Doctor's Guide, 10/17/07 - "The survival rate was 25.52% in the control group versus 63.09% in the ALA group at the end of the 12-month period" - Note:  ALA is the shorter chain omega-3 found in vegetable sources such as flaxseed.
  • Fish Intake and Risk of Incident Atrial Fibrillation - Circulation. 2004 Jul 19 - "Among elderly adults, consumption of tuna or other broiled or baked fish, but not fried fish or fish sandwiches, is associated with lower incidence of AF"
  • Fish Containing N-3 Fatty Acids Reduce Risk of AF - Medscape, 7/19/04 - "Intake of fatty fish containing N-3 fatty acids reduces the risk of atrial fibrillation (AF), but fish sandwiches or fried fish are not protective" - See Mega Twin EPA at Vitacosticon or iHerb.
