Abstract:
Objective: To explore the clinical and anatomical characteristics of coronary slow lfow (CSF) in relevant patients.
Methods: We summarized the patients without coronary angiography (CAG) proved coronary stenosis (stenosis < 40%) while with TIMI indicated CSF in our hospital from 2013-01 to 2015-01. The patients were divided into 2 groups: CSF group, n=56 patients having at least 1 major coronary artery with TIMI frame counts > 27 and Control group,n=55 patients with normal coronary lfow. The related laboratory indexes were examined and relationship between MCV and CSF was studied by multi-logistic regression analysis.
Results: In CSF group, MCV 90.4 (87.48, 92.65) fL and RDW-CV 12.5 (12.30, 13.18) % were lower than those in Control group 92.3 (90.1, 94.3) fL and 13(12.7, 13.4) %,P<0.05; while MCHC 337 (332, 347) g/L and the number of left circumlfex distal braches involved 3 (2, 4) were higher than those in Control group 327.5 (322, 338) g/L and 2 (2, 3),P<0.05. Multi-logistic regression analysis showed that MCV was negatively related to CSF (partial regression coefficient= -0.138, P=0.015), Spearman rank correlation analysis presented that MCV was negatively related to TIMI frame counts (r= -0.201, P=0.009).
Conclusion: Deformability of red blood cells might be involved in pathogenesis of CSF in relevant patients.
