High Calcium Levels Linked to the Higher Risk of Heart Attack
A new study from Karolinska Institutet in Stockholm suggests that high calcium levels in the bloodstream increase the risk of developing coronary artery disease (CAD) and heart attack.
For the study, the researchers analyzed publicly available data collected from 184,305 persons, 60,801 of whom had been diagnosed with CAD. Among these 60,801 individuals, 70% also experienced a heart attack. The scientists discovered that a higher risk of CAD and heart attack was linked to a genetic predisposition to a higher calcium concentration in blood.
Dr. Susanna C. Larsson, the author of the study, says: “Whether the risk of CAD associated with lifelong genetic exposure to increased serum calcium levels can be translated to a risk associated with short-term to medium-term calcium supplementation is unknown.”
