Abnormal Plasma/Serum Magnesium, Copper, and Zinc Concentrations Associate with the Future Development of Cardiovascular Diseases.

Background/

Objectives

Cardiovascular diseases (CVDs) are the leading cause of global mortality. Major adverse cardiovascular events (MACEs)-such as acute myocardial infarction, stroke, and heart failure-are critical endpoints in the clinical research. The existing research has shown metal ions are important regulators of cardiovascular functioning, and defective metal handling may be associated with an increased risk of CVD. This study examines the association of the plasma/serum levels of magnesium, copper, and zinc with MACE incidence and the prevalence of circulatory system diseases, by using electronic health records from a subset of the Scottish population.

Methods

We categorised individuals by high, low, or normal plasma/serum metal levels, and calculated the percentage of those who subsequently developed a MACE, identified using related International Classification of Diseases, 10th Revision codes from hospital admission records. Logistic regression was employed to analyse the association between pre-event metal ion levels and the development of specific circulatory system disease subgroups.

Results

This study found abnormal magnesium, high copper, and low zinc were associated with a higher risk of developing MACEs. Low magnesium, high copper, or low zinc were associated with increased risks of various circulatory diseases, with specific variations, like low copper increasing venous and lymphatic disease risk.

Conclusions

Our findings suggest abnormal plasma metal profiles are associated with the development of MACEs and circulatory disease events, underscoring the importance of monitoring plasma metal levels for cardiovascular risk management and prevention.
