Atherosclerosis plays an important role in the etiopathogenesis of coronary artery ectasia (CAE). Inflammation markers may play a part in the pathogenesis of CAE. We aimed to assess the association between the CAE and the neutrophil-lymphocyte (N/L) ratio. Consecutive eligible patients (n = 181) were divided into 3 groups: patients with CAE, those with newly diagnosed coronary artery disease (CAD), and those with a normal coronary angiogram. The N/L ratio and mean platelet volume (MPV) were measured as part of the automated complete blood count. There were no statistically significant differences in N/L ratio and MPV between the CAE and the CAD groups. The N/L ratio and MPV were significantly higher in patients in both CAE and CAD groups compared to those in the control group (P < .01). An increased N/L ratio may play a role not only in the pathogenesis of CAD but also in the pathophysiology of CAE.

High levels of circulating Von Willebrand factor (vWf) and increased neutrophil to lymphocyte (N/L) ratio may reflect vascular inflammation in hypertensive patients. In present study, we aimed to investigate the effects of valsartan as an angiotensin II receptor antagonist and amlodipine as a calcium channel blocker on the vWf levels and N/L ratio in patients with essential hypertension. Patients were randomized to one of the following intervention protocols: calcium channel blocker (amlodipine, 5-10 mg/day) as group A (n = 20 mean age = 51.85 ± 11.32 y) and angiotensine II receptor blocker (valsartan, 80-320 mg/day) as group B (n = 26 mean age = 49.12 ± 14.12 y). Endothelial dysfunction and vascular inflammation were evaluated with vWf levels and N/L ratio in hypertensive patients before treatment and after treatment in the 12th week. No statistically significant differences were found among the groups in terms of age, sex, and body mass index (BMI). There was a significant decrease in vWf levels (P < .001) and N/L ratio after treatment (P = .04, P < .001, respectively) in both the groups. Von Willebrand factor levels and N/L ratio are very important markers having a role in vascular inflammation and antihypertensive treatment with amlodipine and valsartan may improve cardiovascular outcomes by decreasing these biomarkers.

Serum sTREM-1, IL-6, endocan levels, and I/T ratio increased in septic neonates. However, the diagnostic accuracy of circulating sTREM-1 seemed to be better than endocan and I/T ratio, but lower than IL-6.

The NL ratio is significantly associated with reduced coronary blood flow, and elevated N/L ratio might be an independent predictor for the presence of SCF.

Atherosclerosis plays an important role in the etiopathogenesis of coronary artery ectasia (CAE). The relationship between total bilirubin (TBil) and carotid intima media thickness (cIMT) in patients with CAE has not been fully investigated. Hence, we evaluated the relationship between TBil levels and cIMT in 142 consecutive eligible patients with CAE, newly diagnosed coronary artery disease (CAD), and normal coronary arteries. There were no significant differences in TBil (P = .772) and cIMT (P = .791) between the CAE and CAD groups. Bilirubin levels were significantly lower in both CAE and CAD groups compared to the controls (P < .01). The cIMT was significantly higher in both CAE and CAD groups compared to control participants (P < .01). A negative correlation between cIMT and TBil was found in all the groups (P < .01, r = .354). We show for the first time that patients with CAE and CAD have lower TBil and greater cIMT compared to controls with normal coronary angiograms.
