Genetic Predisposition to High Blood Calcium Linked to Increased Heart Disease Risk

observational studies have noted an association between blood calcium levels and heart disease risk, leading Uppsala University's Karl Michaëlsson and his colleagues to wonder how calcium supplementation might affect disease risk. Using genetic predisposition to increased calcium levels as a proxy, they used a Mendelian randomization approach to examine the link between calcium and heart disease and heart attack risk in about 184,000 individuals. As they reported JAMA, they found an increased risk of disease among people genetically predisposed to higher blood calcium levels.
