After long years of using warfarin for atrial fibrillation, new oral anticoagulants (NOACs) became available for decreasing the risk of ischemic stroke. Our aim was to observe the physicians prescribing patterns of NOACs. This prospective observational study included patients using NOACs applying consecutively to our outpatient clinic. Physical examination was performed, and patient history, electrocardiogram, transthoracic echocardiography, and biochemical results were collected. Bleeding and ischemic stroke risk scores (HAS-BLED and CHA2DS2-VASc scores) were calculated. We evaluated patients' characteristics, risk factors, concomitant drug usage, and physicians' choices. The study consisted of 174 patients using NOACs (dabigatran 113 patients, rivaroxaban 61 patients), with a mean age of 70.7 ± 8.8 years. The mean HAS-BLED score was 1.74 ± 0.9 and the mean CHA2DS2-VASc score was 3.7 ± 1.2. Fifty-three (30.4%) patients were prescribed low-dose NOAC according to the optimal dose, and 12 (6.8%) patients were prescribed high-dose NOAC according to the optimal dose. We compared optimal dose and undertreatment groups to find out if there was any predicting factor for physicians to use low dose of NOACs, but there was no significant difference between the two groups for age, sex, concomitant chronic disease, and CHA2DS2-VASc and HAS-BLED scores. NOACs were prescribed to patients mostly with high CHA2DS2-VASc score and low HAS-BLED score. Low-dose NOAC usage according to the optimal dose was frequent. Frequent coagulation monitoring and drug incompliance are big deficiencies at atrial fibrillation in use of warfarin. NOACs overcome these difficulties; however, physicians' hesitation to use NOACs with the optimal dosage may be another limitation in real-world practice.

Resistin, which is derived from the gene of RSTN, belongs to a family of cysteine-rich secretory proteins called resistin-like molecules (RELMs). Increased serum resistin levels are associated with coronary artery disease (CAD) and the risk of cardiovascular death. Patients (n = 214) with an initial diagnosis of stable angina pectoris, unstable angina pectoris, and myocardial infarction without ST-segment elevation and referred to catheter laboratory for coronary angiography were enrolled in the study. We aimed to investigate the relationship between increased serum resistin level and CAD. The severity of CAD was calculated by the Gensini scoring system. In conclusion, we established a significant correlation between serum resistin levels and CAD (P = .010). Also, serum resistin levels correlated with the Gensini score that represents the severity of CAD angiographically (P = .010).

Objective:Pulmonary artery hypertension (PAH) is characterized by remodeling of the small pulmonary arteries, leading to a progressive increase in pulmonary vascular resistance and right ventricular failure. In this study, we aimed to share our 10 years of experience dealing with pulmonary hypertension (PH) and provide information in real-life settings in terms of demographics, clinical course, PH subgroup distribution, and treatment patterns in patients with PAH in a tertiary center.Methods:In this retrospective, single-center, observational study, we screened the patients who applied to PH outpatient clinic of İstanbul University Institute of Cardiology due to the suspicion of PAH between 2008 and 2017. While group 1, 4, and 5 PH patients were included, group 2 and 3 PH patients were excluded from the study.Results:Our study group comprised 162 patients (115 females, 71%). The female: male ratio was 2.4. The mean age was 52±16 years. Most (86.4%) of the patients were in group 1 PH (PAH). The rest (13.6%, n=22) of the patients were in group 4 PH (chronic thromboembolic PH). In group 1 PH, 45.7% of patients (n=64) were classified as having idiopathic PAH (IPAH) after excluding the alternative diagnosis using PH diagnostic algorithm. The remaining 54.3% of group 1 PH patients (n=76) had various diseases that caused PAH, which is called associated PAH (APAH); APAH group included PAH associated with congenital heart diseases (n=70), connective tissue disorders (scleroderma, n=4) and portal hypertension (n=2).Conclusion:Our data provides important information in real-life settings in terms of demographics, clinical course, PH subgroup distribution, and treatment patterns in patients with PAH in a reference tertiary center in Turkey.
