Association between neutrophil to lymphocyte ratio and severity of coronary artery disease.

The aim of this study is to investigate the association between neutrophil to lymphocyte ratio (NLR) and severity of coronary atherosclerosis. A total of 172 patients undergoing coronary angiography were included in the study. Control group consisted of patients with normal coronary arteries. Patients with coronary stenosis were divided into 2 groups by use of Gensini scores. The NLR was higher in severe atherosclerosis group compared with mild atherosclerosis and control groups (P < .001). In correlation analysis, NLR showed significant correlation with Gensini score. A cutoff value of 2.5 for NLR predicted severe atherosclerosis with a sensitivity and specificity of 62% and 69%, respectively. After multivariate analysis, high levels of NLR were independent predictors of severe atherosclerosis together with glucose and high-density lipoprotein. Our study suggests that the NLR is a predictor of severe atherosclerosis that may be useful for cardiac risk stratification in patients with coronary artery disease.

Platelet Count and Mean Platelet Volume in Patients With In-Hospital Deep Venous Thrombosis

Aim: To investigate the relationship between mean platelet volume (MPV) and in-hospital deep venous thrombosis (DVT). Material and methods: 147 patients with the diagnosis of DVT and 149 control participants were included in the study. For all participants, clinical risk factors, smoking status, and other demographic data were recorded from hospital registries. The data of patients with DVT were compared with the control participants. Results: Mean MPV was significantly higher in patients with DVT than the control group (8.91 ± 1.86 vs 7.86 ± 0.9; P < .001). Body mass index, smoking frequency, hematocrit, and platelet count were significantly correlated with MPV. Independent predictors of in-hospital DVT were MPV (odds ratio [OR] = 1.5; 95% confidence interval [CI] = 1.2-1.87; P ≤ .001), body mass index (OR = 1.17; 95% CI = 1.04-1.34; P = .012), and smoking (OR = 1.83; 95% CI = 1.09-3.08; P = .023). Conclusion: Mean platelet volume was significantly higher in patients with DVT, and it is an independent predictor of in-hospital DVT.

Mean platelet volume in predicting short- and long-term morbidity and mortality in patients with or without ST-segment elevation myocardial infarction

Abstract Mean platelet volume (MPV) is a marker of platelet activation. An increased MPV is associated with acute myocardial infarction (AMI) and long-term mortality. The aim of this study was to compare MPV in patients with ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI). Also, we investigated the value of MPV on in-hospital mortality and long-term prognosis of patients with STEMI and NSTEMI. We studied 429 patients with AMI (70.4% male, 61.9 ± 12.4 years; 279 patients with STEMI, 150 patients with NSTEMI). MPV and platelet count were similar in both groups. Elevated MPV increased the risk of death by 3.1-fold (p < 0.001) in STEMI group during the hospitalization. However, increased MPV was not associated with in-hospital mortality in NSTEMI group. The area under the receiver operating characteristic curve of MPV was 0.868 (95% CI, 0.830–0.907) for predicting two-year mortality. A cut-off point of 11.1 fL showed a sensitivity of 81% and a specifity of 77% for prediction of two-year mortality. Kaplan-Meier survival curve showed two-year mortality rate of 12.5% in patients with MPV >11.1 fL versus 9.9% in patients with MPV <11.1 fL (p < 0.001). Cox regression analysis showed MPV to be an independent predictor of two-year mortality (Hazard ratio 1.7; 95% CI 1.5–1.9; p < 0.001). An increased MPV is an independent predictor of in-hospital mortality in patients with STEMI. However, elevated levels of MPV did not predict in hospital mortality in NSTEMI group. The increase in MPV values was independently correlated with two-year mortality in all study patients.

Relationship between mean platelet volume and varicocele: a preliminary study.

OBJECTIVE To examine the relationship between the mean platelet volume (MPV) and varicocele to clarify the etiopathogenesis of varicocele. METHODS MPV levels were measured in 60 varicocele subjects (group I) and 57 healthy controls (group II) from 2009-2010. Ages were similar between the 2 groups. The diagnosis of varicocele was based on the findings from both physical examination and color Doppler ultrasound. RESULTS The average patient age at the time of examination was 28.12 ± 6.4 years in group I and 28.10 ± 5.8 in group II. MPV levels were statistically significantly higher in group I than in group II (P < .001). Positive correlations were found between MPV and varicocele grade as between MPV and diameter of left spermatic vein (P < .05). CONCLUSION The increase in MPV is independent of the disease, and the increase in varicocele grade is associated with higher MPV in varicocele patients. On the basis of the importance of the vascular component in the pathophysiology of varicocele, we would suggest conducting more studies with platelets in varicocele patients.

The Relationship Between Serum Levels of Zn and Cu and Severity of Coronary Atherosclerosis

The essential trace elements play important roles in the maintainance of the normal structure and physiology of cells. Several research groups have demonstrated that they also play important roles in states of cardiovascular diseases. Our aim is to investigate whether there is a relationship between trace elements (Zn and Cu) and the degree of atherosclerosis. The sample consisted of 67 patients with coronary artery disease and 26 clinically healthy individuals. Ninety-three subjects were separated into four groups according to their Gensini scores, the number of diseased vessels, the presence of acute coronary syndrome, and ejection fraction. Each group was divided into three subgroups, and serum zinc and copper levels were measured for each individual. The serum levels of zinc and copper were found to be significantly lower in patients with atherosclerosis than in the control group, but there were no significant differences in the serum levels of Cu and Zn between severe atherosclerosis and mild atherosclerosis. In Spearman’s rank correlation, the zinc and copper levels were correlated with the Gensini score and the number of diseased vessels. The present study revealed a relationship between the serum levels of zinc and copper and atherosclerosis, but not between these levels and the severity of the disease.

Romano-Ward sendromunda KCNQ1 geninde bir duplikasyon mutasyonu

Long QT syndrome (LQTS), a rare congenital cardiac condition associated with life‐threatening ventricular arrhythmias is characterized by a prolonged QT interval on electrocardiograph corrected for heart rate [corrected QT (QTc)]. LQTS has been historically categorized into the autosomal dominant Romano–Ward syndrome (RWS) and the autosomal recessive Jervell and Lange‐Nielsen syndrome (JLNS). JLNS is associated with prelingual sensorineural deafness. Both types of LQTS can be caused by mutations in channel genes (e.g. KCNQ1) responsible for potassium homeostasis in cardiac myocytes and cochlea. Autosomal dominant mutations often cause the RWS phenotype and homozygous or compound heterozygous mutations contribute to JLNS. Two First Nations communities in northern British Columbia are affected disproportionately with LQTS largely due to the V205M mutation in KCNQ1, however, the pathology and phenotypic expression for those V205M homozygous has been unknown. Here, we show that four V205M homozygous individuals have a significantly higher ‘peak’ QTc, and a more severe cardiac phenotype compared with 41 V205M heterozygous carriers and 57 first to third degree relatives without mutations. Given the lack of prelingual deafness the homozygous V205M LQTS patients present with a phenotype more typical of RWS than JLNS.

Assessment of the neutrophil/lymphocyte ratio in patients with supraventricular tachycardia.

Objective: The neutrophil/lymphocyte ratio (NLR) has been evaluated as a new predictor of cardiovascular risk. Inflammation has been shown to be associated with various arrhythmias including supraventricular tachycardias (SVTs). In this study, we aimed to investigate the relation between NLR and SVT in patients with a documented atrial tachyarrhythmia. Methods: The study used a retrospective cross-sectional design. Patients who had SVT but were otherwise healthy were included. The exclusion criteria included drug use (except antiarrhythmic agents), morbid obesity, acute or chronic infection, inflammatory diseases, systemic diseases, and cancer. Total and differential leukocyte counts and routine biochemical tests were performed before the ablation procedure. Results: The study included 150 patients with SVT and 98 healthy controls. The biochemical and hematological parameters were comparable between the groups, except neutrophil and lymphocyte counts. The neutrophil count was significantly higher (4.7±1.5×103/µL versus 4.1±1.0×103/µL; p<0.001) and lymphocyte count was significantly lower (2.2±0.6×103/µL versus 2.5±0.6×103/µL; p=0.001) in the SVT group than in the control group. As a result, the SVT group had significantly higher NLR values than the control group (2.2±0.9 versus 1.7±0.5; p<0.001). In addition, NLR values were higher in patients in whom tachycardia was induced during an electrophysiological study (EPS) (2.3±0.9 versus 2.0±0.8; p=0.02). The association between NLR and SVT remained significant after multivariate analysis (odds ratio: 1.5, 95% confidence interval: 1.001-2.263, p=0.049). Conclusion: Our study indicated that NLR values were significantly higher in patients with documented SVT than in control subjects. Inducibility of SVT during EPS was associated with higher NLR values.

Myocardial infarction secondary to unintentional ingestion of hydrogen peroxide

Ingestion of acid-containing household products, either accidentally or as a suicide attempt, is a common form of intoxication. A clear and odorless liquid, hydrogen peroxide is an oxidizing agent found in most households and many industrial environments. Cardiovascular manifestations of hydrogen peroxide ingestion are extremely rare. Here we report a 60 year-old woman with acute inferolateral myocardial infarction (MI) after hydrogen peroxide ingestion, who had no history of coronary artery disease. Physicians dealing with hydrogen peroxide ingestion in the emergency department should be aware of the probability of MI and obtain an electrocardiogram, even if the patient has no cardiac complaint.

Unusual metastatic localization of osteosarcoma in a teenager with ventricular tachycardia

Most malignant tumors of the heart are metastatic. Metastatic cardiac tumors are usually associated with Wilms tumor, neuroblastoma, and non-Hodgkin lymphoma in children (Br J Radiol 71:336-339). Osteosarcoma rarely metastasizes to the heart. Twenty-four cases have been reported in the literature so far. The right side of the heart is more commonly involved than the left, and the pericardium and/or myocardium is more frequently involved than the endocardium (Br J Radiol 71:336-339). We report a rare case of osteogenic sarcoma of the right femur with left ventricular metastases presenting with ventricular tachycardia that has not been reported previously. Cardiac tumors are extremely rare, found at a frequency of only 0.001% to 0.28% at autopsy series. The incidence of secondary cardiac tumors is much higher than that of primary cardiac tumors [1]. Secondary intracardiac neoplasms arise most frequently from renal cell carcinoma, bronchogenic carcinoma, Wilms tumor, chondrosarcoma, and osteogenic sarcoma [2]. There are several reports of metastatic childhood osteosarcoma involving the cardiac chambers. However, endocardial left cardiac chamber Fig. 1 Electrocardiogram prese 0735-6757/
