LOWER VITAMIN D HIGHER RISK OF HEART ATTACK SUGGESTS A MEDICAL REPORT
Now it is Vitamin D and the risk of heart attack .It seems like Vitamin D has arrived in the medical spot light. Recently I wrote in healty medical Blog that the Canadian Cancer Society has recommended that many people take Vitamin D and I also scoped out a report that said that women with breast cancer who had low levels of Vitamin D did less well prognosis wise. Now fanning the flames of Vitamin D popularity is a study that says "Low levels of 25(OH)D (Vitamin D) are associated with higher risk of myocardial infarction (heart attack) in a graded manner, even after controlling for factors known to be associated with coronary artery disease" (heart problems related to the coronary arteries that supply the heart muscle itself with blood).
In the report about Vitamin D and the heart they say "Vitamin D deficiency may be involved in the development of atherosclerosis and coronary heart disease in humans".The scientists examined the blood levels of Vitamin D in thousands of men between the ages of 40 and 75. "We assessed prospectively whether (blood) plasma 25-hydroxyvitamin D (25[OH]D) ,(Vitamin D) concentrations are associated with risk of coronary heart disease".
Very few foods in nature contain vitamin D. The flesh of fish (such as salmon, tuna, and mackerel) and fish liver oils are among the best sources. Blood serum concentration of 25(OH)D is the best indicator of Vitamin D status. It reflects vitamin D produced in the skin and that obtained from food and supplements and has a fairly long circulating half-life of 15 days. "A nested case-control study was conducted in 18 225 men in the Health Professionals Follow-up Study; the men were aged 40 to 75 years and were free of diagnosed cardiovascular disease at blood collection. Low levels of 25(OH)D are associated with higher risk of myocardial infarction (heart attack)in a graded manner, even after controlling for factors (that is making adjustments to the calculations for other things that could cause coronary heart problems) known to be associated with coronary artery disease".
