Abstract:
Objective: To explore the relationship between slow coronary lfow (SCF) and characteristics of coronary lumen condition in relevant patients.
Methods: We retrospectively summarized 2117 patients who received coronary angiography (CAG) in Weifang people’s hospital from 2012-08 to 2014-04 and 2 groups of patients were enrolled in our study. SCF group, according to TIMI frame count, the patients had coronary stenosis<50%, without coronary thrombosis, expansion and dissection,n=110. Control group, the patients had normal CAG at meanwhile,n=49. The diameters of left main (dLM), left anterior descending proximal section (dLADp) and middle section (dLADm), left circumlfex (dLCXp) and dLCXm, right coronary artery (dRCAp) and dRCAm were measured; the ratios of dLADp/dLADm, dLCXp/dLCXm, dRCAp/dRCAm were compared between 2 groups.
Results: The ratios of dLADp/dLADm, dLCXp/dLCXm, dRCAp/dRCAm were similar between 2 groups,P>0.05. Compared with Control group, SCF group had increased dLM, increased dLADp and dLADm, dLCXp and dLCXm, dRCAp and dRCAm, allP<0.05. Pearson correlation analysis showed that coronary TIMI frame counts were positively related to the diameters of distal and middle sections of each vessel, the correlation coefifcients in LAD were 0.036 and 0.204, in LCX were 0.368 and 0.183, in RCA were 0.253 and 0.209, allP<0.05. Left coronary TIMI frame count was positively related to the diameter of LM, the correlation coefifcient was 0.501,P<0.05.
Conclusion: Elevated coronary TIMI frame count was related to increased vessel diameter, the expended diameter of left and right coronary arteries may promote SCF development in relevant patients.
