Abstract:
Background Coronary slow flow(CSF)phenomenon is characterized by delayed opacification of coronary vessels in normal coronary angiogram.Although clinical and pathological features have been previously described,its pathogenesis remains unclear.Objective To explore the risk factors related to coronary slow flow.Methods Thirty three patients with documented coronary slow flow which were defined according to TIMI frame count method(TFC)and 33 patients with normal coronary flow were enrolled.Clinical data and biochemical parameters were determined.Results Baseline data analysis showed that CSF group had higher baseline level of platelets count [(149.2?41.5)?109 vs(128.1?38.7)?109,P=0.037] and serum uric acid [(328.1?85.2)vs(282.8?82.4)?mol/L,P=0.032],while other variables were similar between the two groups.After adjustment for BMI,total cholesterol,urea,logistic regression showed that blood platelets count(?2=8.350,?=0.026,P=0.004),2-hour postprandial blood glucose(?2=4.920,?=0.289,P=0.026)and serum uric acid level(?2=5.305,?=0.009,P=0.021)were independent predictors for CSF.Conclusion These data suggest that elevated blood platelets count,2-hour postprandial blood glucose and serum uric acid level may predisposed to coronary slow flow.
