A latest research from UiB reveals that elevated plasma methylmalonic acid predicts elevated threat of acute myocardial infarction and mortality in sufferers with suspected or verified coronary coronary heart illness.
Methylmalonic acid (MMA) is a substance produced from the breakdown of amino acids, odd-chain fatty acids and ldl cholesterol within the physique. MMA focus in blood is reported to be elevated in sufferers with coronary heart illnesses and kidney impairment, and better plasma MMA is taken into account a marker of vitamin B12 deficiency.
In our research, we analyzed the affiliation of plasma MMA with the chance of acute myocardial infarction and loss of life in 7662 members of two massive, unbiased cohorts of sufferers evaluated for both suspected coronary coronary heart illness or verified coronary coronary heart illness.”

They discovered that throughout each cohorts greater MMA in plasma was related to lowered renal perform and low B12 standing at baseline. Nonetheless, greater plasma MMA predicted elevated long-term threat of acute myocardial infarction and complete and cardiovascular deaths unbiased of renal perform and B12 standing.
“This may increasingly recommend that threat relationship between MMA and outcomes will not be defined by vitamin B12 standing or kidney perform alone2, says Dhar.
One other essential discovering findings from this analysis was the optimistic affiliation between plasma MMA and threat of dying as a consequence of non-cardiovascular causes primarily in sufferers evaluated for suspected coronary coronary heart illness, thus warranting additional analysis to discover MMA in a wider perspective past cardiovascular illnesses.
“Future research must also examine the potential position of MMA as an essential regulator of power and lipid metabolism”, Dhar concludes.
