    ABSTRACT: To compare intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) serum levels between patients with stable (SAP) and unstable angina pectoris (USAP) undergoing coronary angiography (CAG), investigate effects of CAG on ICAM-1, VCAM-1 levels in SAP, USAP patients; probable different effects of non-ionic radiocontrast media (RCM), iso-osmotic iodixanol and low osmolar iopamidol, on these adhesion molecules (AM). In this randomized, prospective study, 2 groups consisting of patients with SAP (n=22) and USAP (n=22) undergoing CAG were included. For halves of each group iopamidol, for the other halves iodixanol were used as RCM, in turn for randomization. The patients were divided into 4 subgroups according to clinical presentations and used RCM(SAP-iodixanol, SAP-iopamidol USAP-iodixanol, USAP-iopamidol). ICAM-1, VCAM-1 levels were measured just before and 12 hours after CAG. Repeated measurements were compared with two-way ANOVA test. Baseline VCAM-1 concentration was higher in USAP group than SAP group (p=0.001). ICAM-1, VCAM-1 concentrations increased significantly following CAG in SAP, USAP groups. ICAM-1, VCAM-1 concentration increments; didn't reach statistical significance in SAP-iodixanol subgroup, reached a borderline significance in SAP-iopamidol subgroup (p=0.06, p=0.06). In USAP-iodixanol subgroup; only VCAM-1 (p<0.001), in USAP-iopamidol subgroup; ICAM-1 (p=0.009), VCAM-1 (p=0.006) levels increased significantly following CAG. No complication was observed. To our knowledge, this is the first study indicating ICAM-1, VCAM-1 inducing effect of CAG in patients with SAP, USAP and differential effects of iodixanol and iopamidol on ICAM-1, VCAM-1 serum levels. Further studies are needed to clarify the effects of CAG and different RCM on vascular inflammation, vessel injury, serum AM levels and their clinical significance. This study should be taken as a pilot, hypothesis-generating study.

    ABSTRACT: Aneurysm of the sinus of Valsalva is an uncommon cardiac abnormality; however, the most common complication is rupture into the right heart chambers or rarely towards the left chambers. A ruptured aneurysm typically leads to an aortocardiac shunt and progressively worsening heart failure. We report a case of a 21-year-old male who suffered an aneurysm of the sinus of Valsalva rupture into the right atrium who underwent successful surgical repair.

    ABSTRACT: OBJECTIVE: This cross-sectional, observational study investigated prevalence and clinical features of atrial fibrillation (AF) in diabetic patient groups with or without autonomic neuropathy. METHODS: One hundred and fourteen consecutive patients with pharmacologically treated type-II diabetes mellitus were enrolled for this study in our institution between January 2010 and December 2010. All patients underwent 12-lead electrocardiography on the day of enrollment for AF detection. All diabetic patients underwent neurologic examination for the presence of diabetic autonomic neuropathy (DAN). Following clinical evaluation, sympathetic skin responses (SSR) and RR interval variability (RRIV) analysis were used for the detection of autonomic neurologic involvement. Patients were divided into two groups according to presence (Group 1) or absence (Group 2) of DAN. Patient groups with or without DAN were compared for AF occurrence. Continuous and categorical data were compared with independent samples t- test and Chi-square statistical tests respectively. RESULTS: Atrial fibrillation prevalence was 24% (n=29) in study population. Diabetic autonomic neuropathy was diagnosed in 47 (39%) patients. Basal characteristics of patients with or without DAN were comparable except glycosylated hemoglobin A (HbA1c) levels. HbA1c levels were found significantly higher in patients with DAN. Atrial fibrillation was diagnosed in 14 patients in Group 1 and in 15 patients in Group 2. Significantly increased AF prevalence (31.9% vs. 20.8%, p=0.014, in groups with and without DAN respectively) was observed in patient group with diabetic autonomic neuropathy. CONCLUSION: The results of this study demonstrated an increased prevalence of AF in patients with diabetic autonomic neuropathy compared with non-neuropathic, diabetic patients. Further investigation of this relation with prospective studies is needed to demonstrate a causal relationship between diabetic autonomic neuropathy and AF.

    ABSTRACT: This study investigated the proportion of silent venous obstruction in patients who underwent pacemaker or lead reimplantation for various reasons. We also investigated independent predictors or risk factor of venous obstruction in this patient population. Seventy-three patients who underwent pacemaker pulse generator and/or lead reimplantation in our institution between 2007 and 2010 were enrolled for this retrospective case-control study. Prior to procedure, patients underwent ipsilateral venography. Patients' venographies were classified as non-significant obstruction (stenosis ≤70%, including normal venogram), significant obstruction (stenosis >70%) and complete obstruction. Continuous and categorical data were compared with Mann-Whitney U test and Chi-square statistics respectively. Logistic regression analysis was used to identify independent predictors of venous obstruction. Complete or significant silent central venous obstruction (CVO) proportion was detected as 9.5% (n=7). Basal characteristics of patients with or without CVO were comparable. Significantly increased pacemaker pocket erosion incidence (57% vs 0%, p=0.001, in groups with and without CVO respectively) and significantly higher mean pacemaker age (15.3 ± 10.2 years vs 10.4 ± 5.1 years, p=0.047, in groups with and without CVO respectively) were found in group with CVO. Pacemaker pocket erosion (OR 3.00; 95% CI 1.024-9.302; p=0.001), higher pacemaker age (OR 1.33; 95% CI 1.026-1.733; p=0.02) were found as independent CVO predictors in multiple logistic regression analysis. Correlation analysis also revealed a significant correlation between previous or current pacemaker pocket erosion and CVO (r=0.80, p=0.001). Ipsilateral venography is a useful procedure prior to pacemaker or lead reimplantation to detect CVO. In addition to the increased pacemaker age, current or past history of erosion and infection at pacemaker pocket are probable clinical conditions related to CVO. These clinical conditions create a predisposition to CVO with unknown mechanisms, according to the results of this preliminary study.

    ABSTRACT: Tricuspid annular movement and velocities before and after thrombolytic therapy were investigated for the detection of right ventricular (RV) involvement in RCA (right coronary artery)-related acute inferior myocardial infarction (IMI). Patients with RCA-related acute IMI were evaluated for this pilot prospective cohort study. Annular movement was measured by TAPSE (tricuspid annular plane systolic excursion), and annular velocities were measured by tissue Doppler echocardiography. Data collected before and after thrombolysis and angiography. Diagnosis of RV myocardial infarction (RVMI) was defined by co-presence of electrocardiographic and angiographic criteria. Chi-square and Student's t-tests were used in statistical analysis. Thirty-one patients were included. Before thrombolysis, annular velocities and TAPSE were found significantly higher in patients without RVMI than in patients with RVMI. Comparison of tricuspid systolic velocity (Sa) and movement before and after thrombolytic therapy in patients without RVMI revealed no significant difference (21.6±2.1 mm vs. 21.8±2.0 mm p>0.05 and 136.1±8.8 mm/s vs. 137.5±9.0 mm/s p>0.05, for TAPSE and Sa respectively). Contrarily, in patients with RVMI, TAPSE and systolic velocity increased significantly after thrombolysis compared with pre-thrombolysis (16.2±2.0 mm vs. 17.6±1.8 mm p=0.001 and 110.0±12.6 mm/s vs. 113.08±12.7 mm/s p=0.027 for TAPSE and Sa respectively). Diastolic velocities did not change significantly after thrombolysis in patients with RVMI. Conclusion: Tricuspid annular movement and velocity measurement by echocardiography may contribute to echocardiographic diagnosis of RV involvement in RCA-related IMI. Patients without RVMI have significantly higher annular velocities and TAPSE than in patients with RVMI before thrombolysis. Only in IMI patients with RVMI, significant increases in TAPSE and Sa were observed after thrombolysis.

    ABSTRACT: In this study, we evaluated the possibility that, levels of circulating adhesion molecules following direct stent implantation may be a marker of restenosis. This prospective, observational study investigated levels of circulating intercellular (ICAM-1), and vascular cell (VCAM-1) adhesion molecules in 15 patients with stable angina pectoris before and after coronary stent implantation for single vessel-single lesion disease in proximal left anterior descending artery. All patients received bare-metal stents. Patients underwent repeat coronary angiography for detection of restenosis at 6 month. Continuous data between patients with and without restenosis were compared using Mann-Whitney U test. Repeated measurements were compared using Wilcoxon T test. Categorical data were compared using Chi-square statistics. Baseline ICAM-1 and VCAM-1 concentrations before percutaneous coronary intervention (PCI) were 4.89±2.28 and 46.35±22.96 ng/ml respectively. Levels of ICAM and VCAM increased nonsignificantly 24 hours after PCI (5.01±2.35 ng/ml and 52.57±19.40 ng/ml, respectively). Six patients (40%) developed restenosis within 6 months. Mean stent length, mean stent diameter, and mean dilatation pressure were comparable in patient groups with and without restenosis. Levels of plasma VCAM-1 measured before and after PCI did not change significantly in patients without restenosis. However, these levels increased significantly in the group of restenosis. At 6 months, patients who developed restenosis, had higher VCAM-1 levels, as compared to baseline values (from 45.1±21.0 to 57.2±14.3 ng/ml, p=0.05). Plasma levels of pre and post PCI ICAM-1 did not differ significantly between groups with and without restenosis. These results suggest a more dominant role for VCAM-1, but not for ICAM-1 in development of restenosis following coronary stent implantation.

    ABSTRACT: This prospective observational study investigated predictive power of interatrial conduction time (IACT) and P wave dispersion (PWD), in addition to other atrial fibrillation (AF) predictors, in patients undergoing coronary artery bypass surgery (CABG). Eighty-one patients undergoing CABG were enrolled. Before surgery, IACT and PWD were measured. Time interval from electrocardiographic P wave to echocardiographic transmitral a wave was defined as IACT. Rhythm monitorization was used for AF detection. Continuous and categorical data were compared with independent samples t test and Chi-square statistics. Multiple logistic regression analysis was used to identify independent AF predictors. During a follow-up period of 6.4 ± 2.1 days, AF developed in 14 patients (17%). There were no significant differences between patients with or without AF according to age, gender, number of bypass grafts, cross-clamp duration, systolic function, and left atrial diameter. Significantly increased PWD and IACT were found in AF group (PWD: 37 ± 9 ms vs 24 ± 8 ms, p=0.005 and IACT: 129 ± 11 ms vs 117 ± 11 ms, p=0.01) as compared to group without AF. Increased PWD (OR 1.17; 95% CI 1.04-1.31; p=0.02), absence of beta-blocker treatment (OR 8.88; 95% CI 1.62-48.45; p=0.01), diabetes (DM) and hypertension (HT) combination (OR 1.45; 95% CI 1.15-4.22; p=0.01) were independent AF predictors. However, IACT predictive power had borderline significance (OR 1.03; 95% CI 0.95-1.12; p=0.06). Increased PWD, absence of beta-blocker therapy, HT-DM combination were independent AF predictors following CABG. There was significant difference between groups according to IACT, however predictive value of IACT was nonsignificant. Other studies are needed to establish predictive power of IACT.
