摘      要：BACKGROUND Left ventricular hypertrophy(LVH)is prevalent in obese ***,both of LVH and obesity is as-sociated with subclinical LV *** study aims to investigate the interplay between body fat and LVH in relation to all-cause death in patients with coronary artery disease(CAD).METHODS In this retrospective cohort study,a total of 2243 patients with angiographically proven CAD were *** fat and LV mass were calculated using established *** were grouped according to body fat percentage and pres-ence or absence of ***-proportional hazard models were used to observe the interaction effect of body fat and LVH on all-cause *** Of 2243 patients enrolled,560(25%)had a higher body fat percentage,and 1045(46.6%)had *** a median follow-up of 2.2 years,the cumulative mortality rate was 8.2%in the group with higher body fat and LVH,2.5%in those with lower body fat and no LVH,5.4%in those with higher body fat and no LVH,and 7.8%in those with lower body fat and LVH(log-rank P0.001).There was a statistically significant interaction between body fat percentage and LVH(P interaction was 0.003).After correcting for confounding factors,patients with higher body fat and LVH had the highest risk of all-cause death(HR=3.49,95%CI:1.40-8.69,P=0.007)compared with those with lower body fat and no LVH;in contrast,patients with higher body fat and no LVH had no statistically significant difference in risk of death compared with those with lower body fat and no LVH(HR=2.03,95%CI:0.70-5.92,P=0.195).CONCLUSION A higher body fat percentage was associated with a different risk of all-cause death in patients with CAD,strat-ified by coexistence of LVH or *** body fat was significantly associated with a greater risk of mortality among patients with LVH but not among those without LVH.
