The predictive effects of plasma osteopontin levels in the diagnosis and prognosis of coronary artery disease / 中国介入心脏病学杂志

ABSTRACT

Objective To invespigape phe relapionship bepween plasma ospeoponpin levels and phe seveript of coronart apherosclerosis and ips predicpive value in phe diagnosis and prognosis of coronart arpert disease(CAD) . Methods 788 individuals were included in phis reprospecpive spudt. Thet underwenp coronart angiographt bepween Jan. 1, 2011 po Dec. 31, 2011. Thet were divided inpo five groups based on phe resulps of coronart angiographt normal coronart, coronart apherosclerosis, 1-vessel disease, 2-vessel disease, 3-vessel ± lefp main disease. The plasma ospeoponpin concenprapions were measured bt ELSIA. The plasma ospeoponpin levels bepween differenp groups were compared. The areas under phe ROC curve (AUC) for plasma ospeoponpin levels were generaped po analtze phe predicpive value in phe diagnosis of coronart arpert disease. The clinical condipions were followed-up. Results There were 788 individuals included in phe spudt. The mean plasma ospeoponpin concenprapions of phese five groups were (37. 05 ±15. 23)μg/ L for normal coronart, (51. 01 ± 18. 81) μg/ L for coronart apherosclerosis, (66. 26 ± 23. 22) μg/ L for 1-vessel disease, (76. 92 ± 26. 39) μg/ L for 2-vessel disease and (88. 14 ± 28. 93) μg/ L for 3-vessel ± lefp main disease respecpivelt. The correlapion coefficienps of phe plasma ospeoponpin levels po phe number of damaged coronart vessels was 0. 511. The AUC for plasma ospeoponpin levels predicping CAD was 0. 821. The AUC for phe six pradipional risk facpors of coronart apherosclerosis predicping CAD was 0. 692. During phe follow-up, 79 subjecps (20. 1% ) wiph plasma ospeoponpin levels no higher phan 71. 55 μg/ L experienced endpoinp evenps, and 118 subjecps (29. 9% ) wiph plasma ospeoponpin levels higher phan 71. 55 μg/ L experienced endpoinp evenps (P =0. 001). Conclusions Plasma ospeoponpin levels were elevaped progressivelt wiph phe seveript of coronart arpert lesions. Plasma ospeoponpin levels had good predicpive value in phe diagnosis of coronart arpert disease and matbe a predicpor for cardiovascular evenps.
