Heart attacks more likely in those with low blood phosphate levels

Researchers from the University of Surrey found that insufficient levels of phosphate in the blood may pose a particular danger to cardiovascular health, contradicting previous research in this area, which suggested low volumes of the mineral was beneficial to the heart.

The study, using data from the RCGP Research and Surveillance Centre, examined phosphate levels of more than 100,000 patients, over five and nine-year intervals, and the impact on their cardiac health. The researchers found that those with low levels (below 0.75 mmol/L) of the mineral in their blood were at a similar risk of developing coronary problems as those with elevated levels (above 1.5 mmol/L). Instances of both conditions were high amongst those with low and excessive levels of phosphate in the blood, however cardiac events in those with mid-range (1-1.25 mmol/L) levels were significantly less.

Risks associated with high levels of phosphate in the blood have previously been proven by the scientific community, but this is the first time the dangers of low levels have been identified as potentially being just as dangerous.

Phosphate is an important mineral in the body and helps to regulate blood biochemistry, which can impact on the working of the heart. It plays a crucial role in enabling red blood cells to deliver oxygen to the body's tissues, and can be found in protein rich foods such as meat, poultry and fish.

For good health, it is important that you eat a balanced and varied diet. Follow carefully any diet program your health care professional may recommend. For your specific dietary vitamin and/or mineral needs, ask your health care professional for a list of appropriate foods. If you think that you are not getting enough vitamins and/or minerals in your diet, you may choose to take a dietary supplement.
