Electrophysiological Characterization of Cardiac Veins in Humans

BACKGROUND: The coronary sinus is a complex structure with a surrounding myocardial coat and muscle bundles that course within it. The purpose of this study was to evaluate the electrical activity of the coronary sinus (CS), great cardiac vein (GCV) and related structures, such as the Vein of Marshall (VOM). METHODS AND RESULTS: Data obtained from adult ( n = 114) and pediatric patients ( n = 16) were analyzed. The width of atrial electrograms (EGMs) within the CS at a basic pacing cycle length of 600 ms was 46 +/- 7.4 ms (mean +/- SD) vs. 29.7 +/- 6.3 ms in the GCV ( p < 0.01). With decremental pacing the width of the EGM within the CS at 300 ms increased to 66.6 +/- 8.5 ms ( p < 0.1 compared to CS EGM at pacing cycle length of 600 ms). The width of the EGM within the GCV increased from 29.7 +/- 6.3 ms at a pacing cycle length of 600 ms to 34.6 +/- 6.0 at 300 ms ( p = NS). There were no significant differences in the atrial EGM width between CS and GCV in the pediatric patients. CONCLUSIONS: We conclude that atrial electrograms are wider in the CS but not in the GCV. This finding can be explained by the presence of a myocardial coat around the CS. The rate response characteristics of the atrial electrograms within the CS are consistent with a lack of tight coupling between muscle bundles and the CS musculature. Further, the absence of such differences in pediatric patients could partly explain relative differences in types of supraventricular arrhythmias seen in different age groups.     

Serum gamma-glutamyl transferase activity increased in patients with coronary artery ectasia

BACKGROUND: Serum gamma-glutamyl transferase (GGT) activity, an enzyme responsible for the extracellular catabolism of antioxidant glutathione, may directly take part in atherogenesis and evolve as a potential biochemical risk indicator of cardiovascular morbidity and mortality. An important characteristic of coronary artery ectasia (CAE) is the fact that in 85% of the cases, atherosclerotic coronary disease accompanies it. The relation between CAE and serum GGT activity has not been studied so far. Hence, we decided to investigate the serum GGT level in patients with CAE. METHODS: We measured serum GGT activity in 88 consecutive patients (48 males) with isolated CAE and 86 patients with coronary artery disease (CAD) and 84 controls. CAE was defined as being without any stenotic lesions with a visual assessment of the coronary arteries showing a luminal dilatation 1.5-fold or more of the adjacent normal coronary segments. Four subgroups were created in accordance with the CAE extension in coronary arteries. RESULTS: There were no statistically significant differences in serum GGT activity among CAE and CAD groups. Serum GGT activity was found significantly increased in patients in both CAE and CAD groups, compared with those in control group (P<0.001, P<0.001, respectively). According to the CAE severity, there were no statistically significant differences in CAE among these subgroups. CONCLUSION: We have shown for the first time that patients with CAE have higher serum GGT activity compared with controls with normal coronary angiograms. Hence, serum GGT activity can be used as a follow-up marker in patients with CAE.

Objectives

The authors sought to evaluate the accuracy of instantaneous wave-Free Ratio (iFR) pullback measurements to predict post-percutaneous coronary intervention (PCI) physiological outcomes, and to quantify how often iFR pullback alters PCI strategy in real-world clinical settings.

Transthoracic Echocardiographic Documentation of Disappearance of Massive Pulmonary Artery Thromboemboli after Fibrinolytic Therapy

In this paper, we report two cases of acute massive pulmonary thromboemboli with pulmonary artery thrombus, in which disappearance of thrombus followed fibrinolytic therapy were documented at transthoracic echocardiographic follow-up. Data from these limited experiences suggest that, transthoracic echocardiography might be useful as a first diagnostic screening in cases of suspect pulmonary thromboembolism and thrombolytic therapy might be considered in patients with pulmonary artery thrombus with pulmonary embolism.     

Lung cancer in women: clinical features and factors related to survival

Lung cancer in women is increasing in worldwide. This process beginning with the difference on the susceptibility of lung cancer in women smokers may be different from men in the prognosis. In this study, it was aimed to evaluate the clinical features, and prognostic factors of female patients with lung cancer diagnosed between January 2000-December 2005. The data of 109 patients data was evaluated. The mean age was 59.40 +/- 11.56 and 17 (15.6%) patients were smokers. In 20 patients (18.3%) having a family history of cancer, 55% of them had a relative with lung cancer. In admission, cough (81.7%), dyspnea (78.9%), chest pain (40.3%) were the most frequent presenting symptoms. The most common site of tumoral lesion in bronchoscopy were right upper lobe (16.5%). In the study group histopathological diagnosis were as follows; adenocarcinoma (44.9%), small cell lung cancer (SCLC) (19.3%), squamous cell (10.1%), non-small cell lung cancer (NSCLC) --undefined (22.0%), carsinoid tumors (2.8%), in non-smokers adenocarcinoma was significantly higher than smokers (44.9%/17.7%) (p< 0.001). 61.9% of NSCLC patients and 57.1% of SCLC patients had a stage IV disease at the initial evaluation. The most common sites of metastasis were bone (28.4%), liver (22.9%), and brain (11.9%), there were multiple metastasis in 10 patients. Median survival time was found as 288 days. In univariate analysis, comorbidity, primary tumor stage, bone metastasis, advanced disease stage, ECOG performance score >or= 2 and supportive care alone were poor prognostic factors. In multivariate analysis, poor performance status (p= 0.003), advanced disease stage (p= 0.002) and bone metastasis (p= 0.04) were negatively related to survival. In women, the definition of the clinical features, disease course and survival related factors may contribute to our future treatment approaches based on our national data.

目的探讨聚焦超声经心外膜的环肺静脉消融(CPVa)和左房盒式消融(BOXa)两种不同术式对心房颤动(简称房颤)的影响。方法成年杂种犬20只,随机分为两组,建立肺静脉起源的阵发性房颤模型后,直视下分别行CPVa和BOXa。测定消融前、后左房有效不应期(LAERP)、计算房颤诱发率、房颤持续时间,术毕行组织学检查。结果所有犬均能诱发出肺静脉起源的阵发性房颤,房颤终止后的LAERP较基线水平显著缩短(CPVa组:140±10msvs102±10ms;BOXa组:139±11msvs105±8ms;P均<0.01),但消融前后的LAERP并无显著性差异。消融后两组的房颤诱发率均较消融前显著降低(CPVa组:98%vs28%;BOXa组:97%vs14%;P均<0.01),房颤持续时间均显著缩短(CPVa组:233±40svs70±29s;BOXa组:240±41svs34±22s;P均<0.01);部分犬可见肺静脉-心房双向电传导阻滞;消融后BOXa组房颤诱发率和房颤持续时间低于/短于CPVa组(P<0.05)。消融后焦域内的组织呈凝固性坏死。结论经心外膜聚焦超声CPVa可显著降低房颤诱发率和缩短房颤持续时间,而BOXa则可进一步提高成功率。     

The prevalence of Helicobacter pylori and related factors among university students in Turkey

The frequency and risk factors for contamination of Helicobacter pylori infection was investigated among Sakarya University students. Two-hundred students randomly chosen from among those who volunteered for the study and met its criteria were included. Data were obtained by a questionnaire. H. pylori positivity was checked with the monoclonal H. pylori stool antigen test. Statistical analysis was done with chi-square test. The average age of the subjects was 21.14 +/- 2.06, and 76% of them were female. Monthly family income was below 575 Euros in 69.5% of them, and 56% were living in state dormitories. H. pylori positivity was found to be as high as 63% in our group. According to the qustionnaire (age, gender, blood groups, family income, crowded family living conditions, smoking, alcohol and caffeine consumption, the presence of gastric symptoms, family history, and hygienic behaviors), no statistical differences were found between the H. pylori positive and negative students. These data support the finding that personal and environmental conditions in adults did not affect H. pylori infectivity, and that H. pylori might be acquired in childhood.
