Supplemental Vitamins and Minerals for Cardiovascular Disease Prevention and Treatment
The objective of this study is to explore the current literature supporting the use oral multivitamins and multi/minerals (OMVMs) for cardiovascular diseases (CVD) treatment and prevention.Recent FindingsData on multivitamins, vitamin C and D, coenzyme Q, calcium, and selenium, has showed no consistent benefit for the prevention of CVD, myocardial infarction, or stroke, nor was there a benefit for all-cause mortality to support their routine supplementation. Folic acid alone and B vitamins with folic acid, B6 and B12, reduce stroke, whereas niacin and antioxidants are associated with an increased risk of all-cause mortalit...

Physiological and pathophysiological significance of vitamin B9. Summary on the occasion of the 30-year introduction of folic acid as a dietary supplement.
Abstract Vitamin B9, also known as folate, can be found in natural and synthetic forms, mostly in vegetables or folic acid containing food supplements. By participating in the proper cell development and division, its presence is indispensable for certain basic metabolic processes. The decreased folate level of the body, mainly caused by environmental and hereditary factors as well as aging, can lead to genetic, epigenetic and metabolic changes. It can be related to the development of megaloblastic anemia, various cardiovascular diseases (such as atherosclerosis, stroke) obstetrical complications (such as abruptio...

A Novel Homozygous Non-sense Mutation in the Catalytic Domain of MTHFR Causes Severe 5,10-Methylenetetrahydrofolate Reductase Deficiency
Conclusion: We identified a novel non-sense mutation in MTHFR gene in a single Egyptian family with severe MTHFR deficiency. The present investigation is clinically important, as it adds to the growing list of MTHFR mutations, which might help in genetic counseling of families of affected children and proper genotype-phenotype correlation. Background Severe 5,10-Methylenetetrahydrofolate reductase (MTHFR; OMIM 236250) deficiency is a rare inborn error of metabolism and inherited in an autosomal recessive fashion. It is a very common disorder of folate metabolism and is clinically characterized with low plasma methion...

A genetic deficiency in folic acid metabolism impairs recovery after ischemic stroke.
Abstract Stroke is a leading cause of disability and death world-wide and nutrition is a modifiable risk factor for stroke. Metheylenetetrahydrofolate reductase (MTHFR) is an enzyme involved in the metabolism of folic acid, a B-vitamin. In humans, a polymorphism in MTHFR (677C→T) is linked to increased risk of stroke, but the mechanisms remain unknown. The Mthfr+/- mice mimic a phenotype described in humans at bp677. Using this mouse model, the aim of this study was to investigate the impact of MTHFR deficiency on stroke outcome. Male Mthfr+/- and wildtype littermate control mice were aged (~1.5-year-old) and tr...

The current status of homocysteine as a risk factor for cardiovascular disease: a mini review.
Authors: Chrysant SG, Chrysant GS Abstract INTRODUCTION: Hyperhomocysteinemia has been considered as a risk factor for systemic atherosclerosis, cardiovascular disease (CVD) and stroke and many epidemiologic and case-controlled studies have demonstrated its association with these complications. In addition, treatment of hyperhomocysteinemia with folic acid ± B vitamins prevents the development of atherosclerosis, CVD and strokes. However, subsequent prospective, randomized, placebo- controlled trials have not shown an association of high homocysteine levels or their lowering with treatment with the incidence of at...

Most vitamin, mineral supplements not shown to lower heart disease risk
(American College of Cardiology) Current research does not show enough evidence that vitamin or mineral supplements are beneficial for preventing or treating heart disease, with the exception of folic acid for reducing stroke risk, according to a review article published in the Journal of the American College of Cardiology. Current recommendations to adopt healthy diets that are heavy in plant-based foods from which these vitamins are derived naturally should be reinforced.

Influence of renal function on the association between homocysteine level and risk of ischemic stroke.
We examined whether the association between total homocysteine (tHCY) and risk of ischemic stroke (IS) varies depending on renal function to gain insight into why tHCY-lowering vitamins do not reduce the incidence of cardiovascular disease in clinical trials. We analyzed data from 542 IS patients with large artery atherosclerosis (LAA) or small artery occlusion (SAO) after stratification by estimated glomerular filtration rate (eGFR) to evaluate renal function. We found that tHCY level was positively associated with the occurrence of IS in both LAA (OR: 1.159, 95% CI: 1.074-1.252, P<0.001) and SAO (OR: 1.143, 95% CI: 1....

A specific dietary intervention to restore brain structure and function after ischemic stroke
Occlusion of the middle cerebral artery (MCAo) is among the most common causes of ischemic stroke in humans. Cerebral ischemia leads to brain lesions existing of an irreversibly injured core and an ischemic boundary zone, the penumbra, containing damaged but potentially salvageable tissue. Using a transient occlusion (30 min) of the middle cerebral artery (tMCAo) mouse model in this cross-institutional study we investigated the neurorestorative efficacy of a dietary approach (Fortasyn) comprising docosahexaenoic acid, eicosapentaenoic acid, uridine, choline, phospholipids, folic acid, vitamins B12, B6, C, and E, and seleni...

Homocysteine-lowering interventions for preventing cardiovascular events.
CONCLUSIONS: In this third update of the Cochrane review, there were no differences in effects of homocysteine-lowering interventions in the form of supplements of vitamins B6, B9 or B12 given alone or in combination comparing with placebo on myocardial infarction, death from any cause or adverse events. In terms of stroke, this review found a small difference in effect favouring to homocysteine-lowering interventions in the form of supplements of vitamins B6, B9 or B12 given alone or in combination comparing with placebo.There were uncertain effects of enalapril plus folic acid compared with enalapril on stroke; approxima...

B vitamins in stroke prevention: time to reconsider
Publication date: September 2017 Source:The Lancet Neurology, Volume 16, Issue 9 Author(s): J David Spence, Qilong Yi, Graeme J Hankey B vitamin therapy lowers plasma total homocysteine concentrations, and might be a beneficial intervention for stroke prevention; however, cyanocobalamin (a form of vitamin B12) can accelerate decline in renal function and increase the risk of cardiovascular events in patients with impaired renal function. Although early trials did not show benefit in reduction of stroke, these results might have been due to harm in participants with impaired renal function. In patients with diabetic nephro...
