RESUMEN
The aim of the study was to assess the factors associated with the anticoagulation treatment in patients with atrial fibrillation (AF). A total of 2242 consecutive patients who had been admitted with AF on their electrocardiogram were included in the study. After excluding valvular AF, 1745 patients with nonvalvular AF were analyzed. Mean CHA2DS2-VASc score [cardiac failure, hypertension, age ≥ 75 (doubled), diabetes, stroke (doubled), vascular disease, age 65 -74 and sex category (female)], frequency of persistent/permanent AF, hypertension, diabetes mellitus (DM), stroke history, body mass index, and left atrial diameter were significantly higher in patients receiving anticoagulant therapy. Stroke history, persistent/permanent AF, hypertension, DM, age, heart failure, and left atrial diameter were independent predictors of warfarin prescription. Labile international normalized ratio was the only independent negative predictor of effective treatment with warfarin. In this study, we demonstrated that stroke history, persistent/permanent AF, hypertension, DM, and left atrial diameter were positive predictors, whereas advanced age and heart failure were negative predictors of oral anticoagulant use in patients with nonvalvular AF.

BACKGROUND: AFTER (Atrial Fibrillation in Turkey: Epidemiologic Registry) is a prospective, multicenter study designed with the aim of describing the prevalence and epidemiology of AF practice in Turkey. This study aims to evaluate stroke risk in non-valvular atrial fibrillation (AF) and anticoagulant drug utilization within conformity to AF guidelines. METHODS: Patients were recruited in 17 referral hospitals reflecting all the population of 7 geographical regions of Turkey. 2242 consecutive patients who had been admitted with AF on ECG were included in the study. 1745 of these patients, who had non-valvular AF, were included in the statistical evaluation. Stroke risk was evaluated with the CHA2DS2-VASc score. RESULTS: The average age of participants was determined to be 69.2 ± 11.5 years (56% female). Persistent-permanent AF was found to be the most common type of non-valvular AF (78%). The most common comorbid disorder was hypertension (73%). It was found that oral anticoagulant therapy was used by 40% of all patients, 37% of whom had effective INR (2.0-3.0). Upon multivariate analysis, age was found to be the only independent predictor of stroke among the variables' effects on thromboembolic events that created CHA2DS2-VASc abbreviations (OR 1.026, p < 0.001). CONCLUSIONS: These results suggest that stroke risk scores should be thoroughly heeded based on guidelines, and that anticoagulation must be applied according to their guidance.

OBJECTIVES: Although atrial fibrillation (AF) is one of the most common rhythm disorders observed in clinical practice, a multicenter epidemiological study has not been conducted in our country. This study aimed to assess our clinical approach to AF based upon the records of the first multicenter prospective Atrial Fibrillation in Turkey: Epidemiologic Registry (AFTER) study. STUDY DESIGN: Taking into consideration the distribution of the population in our country, 2242 consecutive patients with at least one AF attack determined by electrocardiographic examination in 17 different tertiary health care centers were included in the study. Inpatients and patients that were admitted to emergency departments were excluded from the study. Epidemiological data of the patients and the treatment administered were assessed. RESULTS: The mean age of the patients was determined as 66.8 ± 12.3 years with female patients representing 60% of the study population. While the most common AF type in the Turkish population was non-valvular AF (78%), persistent/permanent AF was determined in 81% of all patients. Hypertension (%67) was the most common co-morbidity in patients with AF. While a stroke or transient ischemic attack or history of systemic thromboembolism was detected in 15.3% of the patients, bleeding history was recorded in 11.2%. Also, 50% of the patients were on warfarin treatment and 53% were on aspirin treatment at the time of the study. The effective INR level was detected in 41.3% of the patients. The most frequent cause of not receiving anticoagulant therapy was physician neglect. CONCLUSION: These results demonstrate the necessity for improved quality of physician care of patients with AF, especially with regards to antithrombotic therapy.

BACKGROUND: To evaluate whether ambroxol administered orally during the perioperative period has a protective effect against postoperative pulmonary dysfunction in on-pump coronary artery bypass surgery. METHODS: Fifty younger patients without known pulmonary disease were randomly assigned into 2 groups. In ambroxol group (n = 25), patients were given ambroxol for a week before and after the elective coronary artery bypass grafting. In control group (n = 25), placebo was given. Groups were compared with respect to pulmonary function tests (PFTs), lecithin/sphingomyelin (L/S) ratio in the bronchoalveolar lavage fluid, arterial blood gases, and incidence of perioperative morbidity. PFTs were performed before medication and repeated on the postoperative seventh day. Bronchoalveolar lavage fluid was obtained just before cardiopulmonary bypass and within the first postoperative hour. Room air arterial blood gases were checked before and 2 days after the operation. RESULTS: Postoperative lecithin/sphingomyelins were significantly lower than the preoperative values in both groups, but differences between the groups in either preoperative or postoperative measurements were not significant. Although preoperative PaO2 in both groups was similar, it was significantly lower in control group on postoperative second day (62.4 +/- 7.1 vs. 55.2 +/- 6.4 mm Hg, P < 0.05). In either groups, postoperative forced vital capacity and forced expiratory volume in 1 second were significantly lower than preoperative values with a more prominent decrease in control group. Perioperative morbidity was similar. CONCLUSIONS: In on-pump coronary artery bypass grafting, ambroxol improves postoperative PFTs and PaO2 levels without any significant clinical implication, and it exerts these effects possibly in ways other than surfactant modulation.

OBJECTIVE: Genetic bases for novel prothrombotic, inflammatory risk factors may play a role in the early onset of coronary artery disease. METHODS: Twenty-one patients below 35 years of age who underwent coronary bypass grafting between 2002 and 2004 constituted the study group and were compared with 50 healthy, age and sex-matched controls. Gene analysis for genetic polymorphisms of angiotensin-converting enzyme, prothrombin G20210A, tumour necrosis factor-alpha G308A, factor V Leiden and interleukin-6 genes was carried out. RESULTS: The control group was 98% homozygous for the factor V Leiden GG allele and 2% heterozygous for the GA allele. On the other hand, the study group was 76.2% homozygous for the GG allele, and 23.8% heterozygous for the GA allele (P<0.05). Homozygosity for factor V Leiden mutation (AA) was not encountered in either group. With regard to interleukin-6, 70.0% of the control group demonstrated homozygosity for the GG allele and 30.0% showed heterozygosity (GC). The study group was 52.4% homozygous for the GG allele and heterogenicity was similar in this group (28.6% GC). On the other hand, 19.0% of this group demonstrated CC homogenicity (P<0.05). No difference was observed with regard to gene polymorphisms. CONCLUSIONS: Gene polymorphisms with regard to prothrombotic factor V Leiden mutation and inflammatory marker interleukin-6 may play a role in the pathogenesis of early-onset coronary artery stenosis in patients below 35 years of age.
