Correlation analysis between serum calcium level and severity of coronary artery disease

Objective:To analyze the relationship between the severity of coronary atherosclerotic plaque and serum calcium level.Methods:The patients with coronary atherosclerotic heart disease diagnosed by coronary arteriography were divided into the acute myocardial infarction(AMI) group,unstable angina pectoris group(UA) and stable angina group(ASP),and the normal coronary artery was set as the control group.The severity of coronary artery lesion was assessed using SYNTAX scoring system.Results:The serum calcium content in angina group was significantly lower than that in control group(P<0.05),and the serum calcium level in AMI group was significantly lower than that in UA group and ASP group(P<0.05).The serum calcium level was positive correlation with TG(P<0.05),significantly negative correlation with SYNTAX score.The serum levels of K⁺,Na⁺ and Ca²⁺ were positive correlation with EF value(P<0.05 to P<0.01).The low level of serum calcium is the main one factor of coronary heart disease(P<0.05).Conclusions:The lower the serum calcium content,the higher the incidence rate of coronary atherosclerotic plaques is,and the more serious the lesion is.
