Abstract:

Objective To systematically review the correlations among coronary artery calcification score(CACS), coronary artery disease and all-cause mortality. Methods The databases of Pubmed, The Cochrane Library, EMbase, CKNI and WanFang Data were electronically searched to collect cohort studies on the correlations between CACS, CAD and all-cause mortality from the inception of databases to June 2020. Meta analysis was performed with Stata 14.0 software when two data clerks independently screened literatures, they extracted data and assessed risk of bias of included studies. Results A total of 11 cohort studies were included, including 59 143 cases. The Meta results showed that CACS≤100 group [HR=2.46,95%CI(1.77,3.41),P=0.000,I2=55.5%],100<CACS≤400 group[HR=3.62,95%CI(2.24,5.83),P=0.000,I2=42.2%] and CACS>400 group [HR=5.09,95%CI(2.02,12.84),P=0.001,I2=70.7%] are more likely to occur CAD and all-cause deaths compared to CACS<10 group. Conclusion There is a higher risk of coronary artery disease and all-cause mortality for patients with CAC.
