Association Between Bifurcation Angle and Coronary No-reflow Following Primary Percutaneous Coronary Intervention in Patients

Objective:Percutaneous coronary intervention (PCI) has become the treatment method for patients presenting with ST elevation myocardial infarction (STEMI). One of the well-known complications of PCI is no-reflow. Studies demonstrated a relationship between endothelial dysfunction and disturbed vascular flow due to angulation of vascular tree. Although the relationship between hemodynamic alterations and coronary angulation is evident, there is a lack of detailed analysis in terms of hemodynamic changes between vascular geometry and coronary no-reflow. We aimed to elucidate the relationship between vascular geometry and coronary no-reflow.Method:We reviewed PCI database of our hospital and enrolled a total of 120 patients with STEMI, who developed no-reflow following PCI, and sex and age matched 80 patients with normal flow. For each group, demographic and clinical characteristics, laboratory values and two dimensional quantitative coronary angiography measurements were evaluated.Results:Patients with no-reflow had a higher prevalence of hypertension and diabetes mellitus. In addition, serum C-reactive protein levels were higher in patients with no-reflow compared to patients with normal flow (p<0.001). On the other hand, serum hemoglobin levels were significantly lower in patients with no-reflow compared to patients with normal flow (p<0.001). With respect to 3 dimensional coronary measurements, calculated bifurcation angle of left anterior descending artery (LAD) and circumflex artery (CX) was significantly wider in the no-reflow group than in the control group [110.9° (21.8°) vs. 85.9° (15.8°), p<0.001].Conclusion:Our data showed that a strong association existed between bifurcation angle of LAD-CX and no-reflow phenomenon in STEMI patients who underwent PCI

Avrupa Birliği’nin Otoriterlik Sınavı: Macaristan Örneği

As of 2010, there is an increasing authoritarian political structure in Hungary. Winning the elections, the Fidesz government led by Prime Minister Viktor Orbán makes constitutional amendments in line with the party's purposes, guides the media outlets according to its interests, and silences the opponents. The West, which supports democracy even in other countries, has had to struggle with rising authoritarianism within itself. In this study, the rising authoritarianism in Europe and the position of the EU is examined. The study deals with the issue of authoritarianism in Hungary after evaluating the literature on authoritarianism. In the present study, which includes some comparisons with Turkey, a case study has been carried out. It has been conducted through document analysis method, taking into account the reports published by the Venice Commission and Council of Europe. As a result, it is emphasized how the EU remains weak in preventing authoritarianism and that authoritarianism can be not only in non-Western countries but also in the West

The prevalence of microalbuminuria and relevant cardiovascular risk factors in Turkish hypertensive patients.

Objectives: A growing body of data illustrates the importance of microalbuminuria (MAU) as a strong predictor of cardiovascular risk in the hypertensive population. The present study was designed to define the prevalence of MAU and associated cardiovascular risk factors among Turkish hypertensive outpatients. Study design: Representing the Turkish arm of the multinational i-SEARCH study involving 1,750 sites in 26 countries around the world, a total of 1,926 hypertensive patients from different centers were included in this observational and cross-sectional survey study. Patients with reasons for a false-positive MAU test were excluded. The prevalence of MAU was assessed using a dipstick test, and patients were inquired about comorbidities, comedication, and known cardiovascular risk factors. Results: The overall prevalence of MAU was 64.7% and there was no difference between genders. Most of the patients (82.5%) had uncontrolled hypertension, 35.6% had dyslipidemia, and 35.5% had diabetes, predominantly type 2. Almost one-third of the patients (26.4%) had at least one cardiovascular-related comorbidity, with 20.3% having documented coronary artery disease (CAD). Almost all patients (96.8%) had one or more risk factors for cardiovascular disease in addition to hypertension, including family history of myocardial infarction or CAD, diabetes, dyslipidemia, lack of physical exercise, and smoking. A trend towards higher MAU values in the presence of CAD was determined. Conclusion: Microalbuminuria tests should be routinely used as a screening and monitoring tool for the assessment of subsequent cardiovascular morbidity and mortality among hypertensive patients. © 2011 Turkish Society of Cardiology
