Association of the lymphocyte-to-monocyte ratio, mean diameter of coronary arteries, and uric acid level with coronary slow flow in isolated coronary artery ectasia

Abstract Background The pathophysiology of isolated coronary artery ectasia (CAE) with the slow flow (CSF) phenomenon is still unclear. purpose this study was to investigate risk factors for CAE complicated CSF. Methods A total 126 patients were selected retrospectively. grouped into no CSF (NCSF) group (n = 55) and 71) according corrected thrombolysis in myocardial infarction (TIMI) frame count (CTFC). Data on demographics, laboratory measurements, left ventricular ejection fraction (LVEF), end-diastolic diameter (LVEDd), CTFC diameters three arteries collected. Results proportions males (84.5% vs. 61.8%, p 0.004) a smoking history (63.4% 43.6%, 0.021) higher than NCSF group. neutrophil-to-lymphocyte ratio (NLR) (2.08(1.68–3.21) 1.89 ± 0.58, 0.001), mean (mean D) (5.50 0.85 5.18 0.91, < uric acid (URIC) level (370.78 109.79 329.15 79.71, 0.019) significantly group, while lymphocyte-to-monocyte (LMR) (4.81 1.66 5.96 1.75, 0.001) albumin (ALB) (44.13 4.10 45.69 4.11, 0.036) lower. Multivariable logistic analysis showed that LMR (odds ratio: 0.614, 95% CI: 0.464–0.814, D 2.643, 1.54–4.51, URIC 1.006, 1.001–1.012, 0.018) independent predictors CAE. Conclusions negative predictor CAE, positive predictors.
