Abstract
Objective To investigate the ambulatory electrocardiography(AECG)characteristics of coronary slow flow(CSF)phenomenon,and analyze its related influencing factors.Methods The clinical data of 108 patients with suspected coronary heart disease(CHD)who had undergone coronary angiography were retrospectively analyzed.According to the TIMI flow grade,patients were divided into a slow flow group(grade ≤2,n=58)and a normal flow group(grade 3,n=50).All patients underwent 24-hour AECG monitoring to analyze the AECG characteristics of CSF and related influencing factors.Results There were no statistically significant differences between the two groups in age,hypertension,diabetes,history of alcohol consumption,or the use of dual antiplatelet agents,lipid-lowering drugs,ACEI/ARB,calcium channel blockers,beta-blockers or isosorbide mononitrate(all P＞0.05).The proportions of males,smokers,and hyperuricemia were significantly higher in the slow flow group than those in the normal flow group(all P＜0.05).There were no statistically significant differences in the incidence of paroxysmal atrial tachycardia,paroxysmal ventricular tachycardia,atrial premature beats,premature ventricular contraction,T-wave changes,left or right bundle branch block,or atrioventricular block between the two groups(all P＞0.05).No statistically significant differences were observed in pNN50,SDANN or rMSSD(all P＞0.05).The maximum heart rate and SDNN were significantly lower in the slow flow group than those in the normal flow group(both P＜0.05).There were no statistically significant differences in hemoglobin,total cholesterol,triglycerides,alanine aminotransferase,aspartate aminotransferase,albumin,thrombin time,or D-dimer levels between the two groups(all P＞0.05).Hematocrit was significantly higher in the slow flow group than that in the normal flow group(P＜0.05).Five factors related to general information,AECG findings,and blood test results that affected the CSF phenomenon were selected for multivariate Logistic regression analysis.It showed that male,smoking history,hyperuricemia,low maximum heart rate,and low SDNN were independent influencing factors for CSF phenomenon.Conclusion Male sex,smoking history,hyperuricemia,low maximum heart rate,and low SDNN are independent related factors for coronary slow flow phenomenon and hold significant value in predicting CSF in patients with coronary heart disease.关键词
