Abstract:
Objective:The goal of this study was to analyze the clinical significance of relationship between myocardial collateral and the levels of hypoxia‐inducible factor 1‐alpha (HIF‐1α) and vascular endothelial growth factor A (VEGF‐A) in patients with coronary chronic total occlusion lesion .Methods:89 patients with coronary chronic total occlusion lesion confirmed by clin‐ical data and coronary angiography were identified .The levels of HIF‐1αand VEGF‐A were measured by ELISA ,and the rela‐tive expression of VEGF‐A of peripheral blood mononuclear cell (PBMC) were measured by real‐time PCR .The results were statistically analyzed by the statistical programme for social sciences (SPSS version 18 .0) and software SAS JMP 9 .0 .Results:Compared to Rentrop 0‐1 grade group (18/38 ,47 .4% ) ,Rentrop 2 (11/31 ,35 .5% ) and Rentrop 3 (3/20 ,15 .0% ) grade group had fewer diabetes mellitus .Rentrop 2 [(6 .67 ± 1 .41) mmol/L] and Rentrop 3 [(5 .48 ± 1 .26) mmol/L] grade group had low‐er fasting blood glucose than Rentrop 0‐1 grade group [(7 .24 ± 1 .39) mmol/L] .Rentrop 2 (12/31 ,38 .7% ) and Rentrop 3 (3/20 ,15 .0% ) grade group had fewer clinical heart failure (NYHA Ⅱ ~ Ⅳ grade) than Rentrop 0‐1 grade group (20/38 , 52 .6% ) .Rentrop 2 [(85 .5 ± 27 .7) pg/mL ,(139 .5 ± 42 .1) pg/mL] and Rentrop 3 [(103 .3 ± 30 .2) pg/mL ,(162 .6 ± 43 .3) pg/mL] grade group had higher levels of HIF‐1αand VEGF‐A than Rentrop 0‐1 grade group [(42 .0 ± 16 .1) pg/mL ,(76 .5 ± 32 .2) pg/mL] .Rentrop 2 (1 .31 ± 0 .46) and Rentrop 3 (1 .38 ± 0 .44) grade group had higher level of relative expression of VEGF‐A in PBMC than Rentrop 0‐1 grade group (1 .00 ± 0 .28) .Conclusions:Chronic and consistent ischemia and hypoxia in‐duced the increase of expression of HIF‐1αand VEGF‐A is important for establishment of coronary collateral ,increasing blood supply and improving the heart function and prognosis .
