Abstract:Objective: To explore the correlation between serum magnesium levels and coronary artery disease (CAD) complicated with diabetes. Methods: A total of 467 eligible inpatients with suspected CAD from January 2015 to June 2017 in our hospital were consecutively enrolled in the study. All of them were divided into CAD diabetes (n=129), CAD non-diabetes (n=201), non-CAD diabetes (n=33), and non-CAD non-diabetic group (n=104). Clinical data was collected and total coronary artery calcification (CAC) score was calculated. Multivariate logistic regression model was used to analyze the risk factors of CAD complicated with diabetes. Results: Dyslipidemia, pulse pressure≥60mmHg, CAC score>400, EF<50% and serum magnesium≤0.77mmol/L are all risk factors for CAD with diabetes, serum magnesium≤0.77mmol/L being the highest risk. The risk of serum magnesium decreased in CAD with diabetes group was 2.806 times higher than control group (P<0.05). Conclusion: Serum magnesium decreased is an independent risk factor of CAD complicated with diabetes, which can be used as a biomarker of reference for clinical diagnosis.
