Objectives The neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) are measures of systemic inflammation. Heart rate recovery (HRR) after exercise is influenced by autonomic function. The aim of this study was to ascertain whether HRR and the Duke Treadmill Score (DTS) values are related to NLR and PLR in patients with cardiac syndrome X (CSX). Methods A total of 350 participants were enrolled in the study. Complete blood counts and high-sensitivity C-reactive protein (hsCRP) were obtained. All participants underwent an exercise test. HRR and DTS were calculated after exercise. Abnormal HRR was defined as 12 beats/min or less. Results CSX and coronary artery disease (CAD) groups had higher NLR, PLR, and hsCRP, and lower HRR and DTS values than the control group (for all, P<0.05). In both CSX and CAD groups, HRR was positively correlated with DTS (r=0.468, P<0.001 and r=0.491, P<0.001, respectively) and negatively correlated with NLR (r=-0.519, P<0.001 and r=-0.612, P<0.001, respectively), PLR (r=-0.422, P<0.001 and r=-0.438, P<0.001, respectively), and hsCRP (r=-0.553, P<0.001 and r=-0.521, P<0.001, respectively). NLR and hsCRP were important two predictors of the presence of lower HRR in both CSX [NLR: odds ratio (OR), 0.395; 95% confidence interval (CI), 0.168-0.925; P=0.032 and hsCRP: OR, 0.748; 95% CI, 0.591-0.945; P=0.015], and CAD groups (NLR: OR, 0.115; 95% CI, 0.026-0.501; P=0.004 and hsCRP: OR, 0.637; 95% CI, 0.455-0.892; P=0.009). Conclusion CSX patients have higher NLR and PLR and slower HRR and lower DTS, similar to CAD patients, suggesting that CSX patients may be at a higher risk for developing cardiovascular events in the future. NLR may predict autonomic imbalance assessed by HRR in CSX. (C) 2014 Wolters Kluwer Health vertical bar Lippincott Williams & Wilkins.
Neutrophil-To Ratio May Predict Subclinical Atherosclerosis in Patients With Psoriasis
(Wiley, 2014) Yurtdas, Mustafa; Yaylali, Yalin T.; Kaya, Yuksel; Ozdemir, Mahmut; Ozkan, Ilker; Aladag, Nesim
Background: Systemic inflammation beyond the skin may provide an explanation of the increased cardiovascular risk observed in psoriasis. It was hypothesized that neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are potential predictors of subclinical atherosclerosis measured by aortic velocity propagation (AVP) and carotid intima-media thickness (CIMT) in psoriasis. Methods: Fifty-one patients with psoriasis taking no antipsoriatic therapy and 37 age- and sex-matched healthy controls were prospectively enrolled. The Psoriasis Area and Severity Index (PASI) was calculated. Complete blood counts were obtained. Measurements of AVP and CIMT were performed. Results: The baseline clinical and demographic features, and white blood cell, platelet, neutrophil, lymphocyte, monocyte, and PLR were similar in both groups. NLR and high-sensitivity C-reactive protein (hs-CRP) were higher in the psoriasis group than the control group (P = 0.001, P < 0.001; respectively). The psoriasis group had lower AVP and higher CIMT values than those of controls (AVP: 48.9 +/- 18.1 vs. 64.3 +/- 14.5 cm/sec; P < 0.001, CIMT: 0.84 +/- 0.29 vs. 0.63 +/- 0.27 mm; P = 0.001, respectively). PASI was positively correlated with NLR and hs-CRP (r = 0.423, P = 0.002; r = 0.315, P = 0.024, respectively). There was an inverse association between AVP and CIMT (r = -0.749, P < 0.001). Binary logistic regression analysis demonstrated that NLR was the only variable able to predict lower AVP (= 41 cm/sec) and higher CIMT (>0.9 mm) values (P = 0.024 and 0.023; respectively). Conclusion: NLR is potentially an unrecognized predictor of subclinical atherosclerosis in patients with psoriasis. Future studies assessing the prognostic significance of NLR on cardiovascular event rates in psoriasis patients would be of great interest.
