RESULTS Data were collected for 1068 enrolled patients undergoing coronary angiography for clinical indications during the period of April 1^(st),2013 to March 30^(th),2014. Ethnicities of spouses were available only for male patients. Of those enrolled,687 were married men and constituted the cohort for the present analysis. Intra-ethnic marriages were reported in 70% and inter-ethnic marriages in 30%. After adjusting for baseline differences,interethnic marriage was associated with lower odds of having significant CAD [adjusted odds ratio 0.52(95%CI:0.33,0.81)] or multi-vessel disease(MVD) [adjusted odds ratio 0.57(95%CI:0.37,0.86)]. The adjusted association with left main disease showed a similar trend,but was not statistically significant [adjusted odds ratio 0.74(95%CI:0.41,1.32)]. The association between interethnic marriage and the presence of significant CAD and MVD was not modified by number of concurrent wives(P interaction > 0.05 for both).CONCLUSION Among married men undergoing coronary angiography,inter-ethnic,as compared to intra-ethnic,marriage is associated with lower odds of significant CAD and MVD.展开更多
