Relationship between slow coronary flow and vascular endothelial function / 心血管康复医学杂志

ABSTRACT

Objective:To study and analyze the relationship between slow coronary flow (SCF) and vascular endothelial func‐tion .Methods:A total of 88 patients ,who received coronary angiography in our hospital from Jan 2014 to Dec 2014 ,were selected .TIMI blood flow classification was used to assess coronary flow velocity of all patients .The CTFC (corrected TI‐MI frame count ) >27 frames was regarded as slow flow .The patients with slow flow were regarded as SCF group (n=43) , and those with normal blood flow were regarded as normal control group (n=45) .Levels of blood pressure ,blood glucose and blood lipids ,and vascular endothelial function were measured and compared between two groups .Logistic regression a‐nalysis was used to analyze the relationship between SCF and vascular endothelial function .Results:There were no signifi‐cant difference in levels of blood pressure ,blood glucose and blood lipids between two groups , P>0. 05 all .Compared with normal control group , there were significant reductions in fore brachial artery flow‐mediated vascular diastolic function [FMD ,(8. 33 ± 2. 04 )% vs . (7. 06 ± 1. 78 )% ] and nitroglycerin mediated vasodilation [NMD , (20. 39 ± 4. 13 )% vs . (16.10 ± 5.22)% ] in SCF group ,P<0.01 both .Logistic regression analysis indicated that reduced FMD (OR=1.069 ,P=0.011) and NMD (OR=1.183 ,P=0.014) were risk factors for SCF .Conclusion:The vascular endothelial dysfunction is a risk factor of slow coronary flow .
