(Baishideng Publishing Group inc, 2013) Ilhan, Erkan; Kaplan, Abdullah; Guvenc, Tolga Sinan; Biteker, Murat; Karabulut, Evindar; Isikli, Serhan
Aim: To analyze electrocardiographic features of patients diagnosed with posttraumatic stress disorder (PTSD) after the Van-Ercis earthquake, with a shock measuring 7.2 on the Richter scale that took place in Turkey in October 2011. METHODS: Surface electrocardiograms of 12 patients with PTSD admitted to Van Ercis State Hospital (Van, Turkey) from February 2012 to May 2012 were examined. Psychiatric interviews of the sex and age matched control subjects, who had experienced the earthquake, confirmed the absence of any known diagnosable psychiatric conditions in the control group. RESULTS: A wide range of electrocardiogram (ECG) parameters, such as P-wave dispersion, QT dispersion, QT interval, Tpeak to Tend interval, intrinsicoid deflection durations and other traditional parameters were similar in both groups. There was no one with an abnormal P wave axis, short or long PR interval, long or short QT interval, negative T wave in lateral leads, abnormal T wave axis, abnormal left or right intrinsicoid deflection duration, low voltage, left bundle branch block, right bundle branch block, left posterior hemiblock, left or right axis deviation, left ventricular hypertrophy, right or left atrial enlargement and pathological q(Q) wave in either group. CONCLUSION: The study showed no direct effect of earthquake related PTSD on surface ECG in young patients. So, we propose that PTSD has no direct effect on surface ECG but may cause electrocardiographic changes indirectly by triggering atherosclerosis and/or contributing to the ongoing atherosclerotic process.

False Positive Troponin Levels Due To Heterophil Antibodies in a Pregnant Woman
(Elsevier Science Bv, 2015) Kaplan, Abdullah; Orhan, Nuri; Ilhan, Erkan
Positive troponin test results in peripheral blood can be detected either during myocardial injury or from falsely positive test results. In this report, we present the positive results of a troponin test in a 24-year-old pregnant woman referred to the emergency department with atypical chest pain, and the clinical algorithm that we used to make the correct diagnosis. This patient presented with the same complaint of chest pain at different times while positive troponin levels were detected. In the absence of signs of myocardial injury, we suspected that heterophil antibodies were playing a major role. Further examinations revealed heterophil antibodies that could cross react with the troponin tests in peripheral blood.
Incidence, Risk Factors, and Outcomes of Perioperative Acute Kidney Injury in Noncardiac and Nonvascular Surgery
(Excerpta Medica inc-elsevier Science inc, 2014) Biteker, Murat; Dayan, Akin; Tekkesin, Ahmet Ilker; Can, Mehmet M.; Tayci, Ibrahim; Ilhan, Erkan; Sahin, Gulizar
BACKGROUND: The aim of this study was to determine the incidence rate, identify the risk factors, and describe the clinical outcome of perioperative acute kidney injury (AKI) in patients undergoing noncardiac, nonvascular surgery (NCS). METHODS: A total of 1,200 adult consecutive patients undergoing NCS were prospectively evaluated. Patients with pre-existing renal dysfunction were excluded. The primary outcome of this study was perioperative AKI defined by the RIFLE (risk, injury, failure, loss of function, and end-stage kidney disease) criteria. RESULTS: Eighty-one patients (6.7%) met the AKI criteria. Multivariate analysis identified age, diabetes, revised cardiac risk index, and American Society of Anesthesiologists physical status as independent predictors of AKI. Patients with AKI had more cardiovascular (33.3% vs 11.3%, P < .001) complications and a higher in-hospital mortality rate (6.1% vs 0.9%, P = .003) compared with patients without AKI. CONCLUSIONS: Several preoperative predictors are found to be associated with AKI after NCS. Perioperative AKI is an independent risk factor for outcome after NCS. (C) 2014 Elsevier Inc.

Outcome of Noncardiac and Nonvascular Surgery in Patients With Mechanical Heart Valves
(Excerpta Medica inc-elsevier Science inc, 2012) Biteker, Murat; Tekkesin, Ahmet Ilker; Can, Mehmet Mustafa; Dayan, Akin; Ilhan, Erkan; Turkmen, Funda Muserref
There is a tendency to avoid noncardiac surgery in patients with mechanical heart valves (MHVs) owing to the increased risk of perioperative thromboembolism, infective endocarditis, and bleeding. We aimed to determine the risk of cardiac and noncardiac complications in patients with MHVs who underwent noncardiothoracic, nonvascular surgery. A total of 140 patients with MHVs (77 aortic, 46 mitral, and 17 double valve) and 1,200 patients with native valves (control group) were prospectively followed up for a minimum of 3 months after noncardiothoracic and nonvascular surgery. Patients with bioprostheses were excluded. Those patients aged >18 years who underwent an elective, non-outpatient, open surgical procedure were enrolled. Subcutaneous enoxaparin 1 mg/kg, twice daily, was used as bridging anticoagulation. The demographics, co-morbidities, and preoperative (medications, echocardiographic findings, laboratory results) and postoperative data were evaluated for their association with the occurrence of perioperative adverse events. The incidence of perioperative adverse cardiovascular (10.8% vs 10.7%, p = 0.985) and non-cardiovascular (11.9% vs 11.4%, p = 0.989) events was similar in those patients with and without MHVs. Bleeding (18.6% vs 14.2%, p = 0.989), thromboembolism (3.6% vs 2%, p = 0.989), and mortality at 3 months (1.4% vs 1.3%, p = 0.825) were also similar for the 2 groups. In conclusion, with close follow-up and strict adherence to the guidelines, patients with MHVs and patients with native heart valves undergoing noncardiac and nonvascular surgery have a similar risk of mortality and morbidity.

Predictive Value of Red Cell Distribution Width in Intrahospital Mortality and Postintervention Thrombolysis in Myocardial Infarction Flow in Patients With Acute Anterior Myocardial Infarction
(Lippincott Williams & Wilkins, 2012) Ilhan, Erkan; Guvenc, Tolga S.; Altay, Servet; Cagdas, Metin; Calik, Ali N.; Karaca, Mehmet; Tayyareci, Gulsah
Objectives Recent studies have reported a strong independent association between increased red cell distribution width (RDW) and the risk of adverse outcomes in patients with heart failure, stable coronary disease, and acute coronary syndromes. However, in this study we aimed to determine the impact of an elevated RDW level on the postinterventional thrombolysis in myocardial infarction (TIMI) flow and intrahospital mortality in patients with acute anterior myocardial infarction (AMI). Methods A total of 763 patients with acute AMI undergoing a primary percutaneous coronary intervention were evaluated retrospectively. Upon admission, the RDW level was measured by an automated complete blood count. Postinterventional TIMI flow and intrahospital mortality was documented for all patients from hospital registries. The patients were classified according to the RDW level. RDW more than 14.8% was defined as elevated RDW. All groups were compared statistically according to the preinterventional characteristics. Results Elevated RDW was found to be an independent predictor of increased intrahospital mortality in multivariate regression analysis (hazard ratio: 3.677, 95% confidence interval: 1.228-11.008, P=0.02). Other independent predictors for intrahospital mortality were diabetes mellitus (hazard ratio: 6.743, 95% confidence interval: 1.941-23.420, P=0.003), smoking (hazard ratio: 6.779, 95% confidence interval: 1.505-30.534, P=0.013), and creatinine more than 0.8 mg/dl (hazard ratio: 7.982, 95% confidence interval: 1.759-36.211, P=0.007). However, there were no independent predictors for TIMI including elevated RDW. Conclusion A high admission RDW level in patients with acute AMI undergoing a primary percutaneous coronary intervention was associated with an increased risk for intrahospital cardiovascular mortality, but was not associated with worse postinterventional TIMI flow.
