Öğe Association of pulmonary artery obstruction index with elevated heart-type fatty acid binding protein and short-term mortality in patients with pulmonary embolism at intermediate risk(Turkish Soc Radiology, 2012) Gul, Enes Elvin; Can, Ilknur; Guler, Ibrahim; Yesildag, Ahmet; Abdulhalikov, Turyan; Kayrak, Mehmet; Ozdemir, KurtulusPURPOSE Heart-type fatty acid binding protein (H-FABP) is a sensitive marker of myocardial injury and predictor of worse prognosis in patients with pulmonary embolism (PE). Assessment of right ventricular dysfunction and pulmonary artery obstruction index (PAOI) with computed tomography (CT) has been reported as a predictor of mortality in PE. Therefore, we aimed to assess the correlation between H-FABP and CT angiographic PAOI in PE patients at intermediate risk. MATERIALS AND METHODS Sixty-one patients (28 males; mean age, 62 +/- 17 years) with diagnosis of PE were included in this study. CT was performed in all patients, and the following parameters were evaluated: right ventricle/left ventricle ratio (RV/LV), pulmonary artery axial diameter, superior vena cava axial diameter, and PAOI determined with Qanadli score. Blood samples were assessed for H-FABP and troponin levels. Patients were followed for 30 days after discharge. RESULTS Mean PAOI was 57 +/- 18%. Eleven patients died during the follow-up period due to PE (18% mortality rate). H-FABP was positive in 21 patients (35%). There was no difference in CT parameters between patients with positive H-FABP and negative H-FABP. In addition, CT parameters were similar between patients who survived and those who did not. RV/LV ratio correlated with PAOI score. Among the biomarkers, troponin levels correlated with both RV/LV ratio and PAOI. H-FABP was an independent predictor of mortality. PAOI and RV/LV ratio did not predict 30-day mortality. CONCLUSION Although H-FABP positivity confers a bad prognosis on PE patients at intermediate risk, PAOI did not predict mortality in this group.Öğe Case Report: An Unusual Heart Rhythm Associated with Organophosphate Poisoning(Humana Press Inc, 2012) Gul, Enes Elvin; Can, Ilknur; Kusumoto, Fred M.Organophosphate pesticides have emerged as a common cause of poisoning, particularly in developing countries. The most common electrocardiographic abnormalities observed in organophosphate poisoning are sinus tachycardia, QT interval prolongation, and, very rarely, ventricular arrhythmias. We report a case of organophosphate poisoning associated with atrial fibrillation, right bundle branch block, QT interval prolongation, and intermittent narrow QRS complexes that were most likely due to automaticity from the region of the left posterior fascicle.Öğe Inappropriate sensing events revealing electrocautery-induced implantable cardioverter-defibrillator lead failure(Turkish Soc Cardiology, 2015) Can, Ilknur; Aribas, Alpay; Dereli, Yuksel; Tholakanalli, Venkatakrishna[Abstract Not Availabe]Öğe Pyridostigmine treatment in postural orthostatic tachycardia syndrome(Turkish Soc Cardiology, 2014) Can, Ilknur; Tholakanahalli, VenkatakrishnaA 34-year-old female patient was admitted with the complaints of inability to stand upright, palpitations, dizziness, and fatigue in the upright posture for the last one year. She was found to stand upright for less than one minute without symptoms. Tilt table testing showed that, compared to baseline her heart rate increased 55 beats/min in the fifth minute of the test with the symptoms of palpitations, fatigue and sweating without any signifcant change in her blood pressure. Postural orthostatic tachycardia syndrome was diagnosed, and pyridostigmine treatment was started. Four months after treatment her symptoms were relieved so that she was able to function as a nurse.Öğe Thrombolysis in patients with pulmonary embolism and elevated heart-type fatty acid-binding protein levels(Springer, 2014) Gul, Enes Elvin; Can, Ilknur; Kayrak, Mehmet; Abdulhalikov, Turyan; Erdogan, Halil Ibrahim; Altunbas, Gokhan; Ozdemir, KurtulusRecent studies have reported that a novel cardiac biomarker, heart-type fatty acid-binding protein (h-FABP), significantly predicts mortality inpatients with pulmonary embolism (PE) at intermediate risk. The aim of this study was to evaluate the effect of thrombolytic therapy on prognosis of the intermediate risk acute PE patients with elevated levels of h-FABP. This is non-interventional, prospective, and single-center cohort study where 80 patients (mean age 62 +/- A 17 years, 32 men) with confirmed acute PE were included. Only patients with PE at intermediate risk (echocardiographic signs of right ventricular overload but without evidence for hypotension or shock) were included in the study. h-FABP and other biomarkers were measured upon admission to the emergency department. Thrombolytic (Thrl) therapy was administered at the physician's discretion. Of the included 80 patients, 24 were h-FABP positive (30 %). 14 patients (58 %) with positive h-FABP had clinical deterioration during the hospital course and required inotropic support and 12 of these patients died. However, of 56 patients with negative test, only 7 patients worsened or needed inotropic support and five patients died during the hospital stay. Mortality of patients with PE at intermediate risk was 21 %. The 30-day mortality rate was significantly higher in h-FABP(+) patients compared to h-FABP(-) patients (9 vs. 50 %, p < 0.001). Multivariate analysis revealed h-FABP as the only 30 day mortality predictor (HR 7.81, CI 1.59-38.34, p = 0.01). However, thrl therapy did dot affect the survival of these high-risk patients. Despite, h-FABP was successful to predict 30-days mortality in patients with PE at intermediate risk; it is suggested to be failed in determining the patients who will benefit from thrl therapy.
