Objective: To explore the relationship between the ratio of neutrophil/lymphocyte (NLR) and in-hospital major adverse cardiac events (MACE) in patients with acute ST-elevation myocardial infarction (STEMI) at early admission.
Methods: A total of 420 acute STEMI patients admitted and received primary PCI in our hospital from 2010-01 to 2014-12 were retrospectively studied. The patients were divided into 2 groups:In-hospital MACE group, n=47 and Normal discharged group, n=373. Uni-and multivariate analyses were conducted to assess whether high NLR is the independent predictor for in-hospital MACE occurrence.
Results: Univariate regression analysis indicated that the occurrence rate of in-hospital MACE in high NLR patients were higher than those in low NLR patients (OR=3.19, 95%CI 1.55-2.65, P=0.012). Multivariate regression analysis showed that high NLR was the independent risk factor for in-hospital MACE occurrence in STEMI patients (OR=3.05, 95%CI 1.59-10.54, P=0.015).
Conclusion: High NLR is the independent risk factor for in-hospital MACE occurrence in STEMI patients at the early admission.

Objective To analyze the risk factors of paroxysmal atrial fibrillation (PAF) in very olderly hypertensive patients. Methods According to the electrocardiograph (ECG) and history data, two hundred and six older old-hypertensive patients were divided into PAF group (n=66) and sinus rhythm (SR) group (n=140). Data of age, gender, body mass index (BMI), the use of angiotension-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs) and statin drug history, 24-hour ambulatory blood pressure monitoring (ABPM), echocardiography, pulse wave velocity (PWV), blood lipid profile and renal function were recorded in two groups. Logistic regression analyses of the relevant factors were compared between groups. Results Data of age, the diameter of the left atrium (LAD), the 1eft ventricular mass index (LVMI) and the PWV were significantly higher in PAF group than those of SR group [(88.92±3.42) years old vs. (86.36±4.67) years old, (39.00±6.66) mm vs. (33.54±7.77) mm, (132.49±14.83) g vs. (119.00±11.35) g, (13.45±4.85) m/s vs. (9.89±2.74) m/s, respectively]. Values of three acyl glycerin (TG), blood pressure smoothing index (SI) were lower in PAF group than those of SR group [(1.33±0.91) mmol/L vs. (1.95±1.29) mmol/L, 0.75±0.06 vs. 0.79±0.04, respectively]. Results of two classification Logistic regression analyses showed that the reduced SI, the enlarged LAD and LVMI and the increased PWV were the risk factors of PAF in very olderly hypertensive patients. Conclusion Unstable blood pressure, left atrial enlargement, left ventricular hypertrophy and arterial stiffness are the risk factors of PAF in very olderly hypertensive patients.
