Öğe Öğe Coronary slow flow and acute coronary syndrome in a patient with spinal cord injury(2011) Aktoz M.; Tatli E.; Barutcu A.; Ozkalayci F.; Umit E.; Altun A.We report the case of a 55-year-old man who presented with acute coronary syndrome due to coronary slow flow after spinal cord injury. Data regarding the causes and clinical manifestations of coronary slow flow are inconclusive, but the autonomic nervous system is believed to be at least a contributing factor. The predominant vagal activity causes vasodilation and hemostasis, which can lead to acute coronary syndrome. We hereby call attention to hyperactive parasympathetic tonicity, which can lead to coronary slow flow and acute coronary syndrome in acute spinal cord injury patients. © 2011 by the Texas Heart®Institute, Houston.Öğe The longest documented left main coronary artery(2009) Tatli E.; Aktoz M.; Aydin G.; Barutçtu A.[No abstract available]Öğe Macitentaninthetreatmentofpulmonary hypertension in Gaucher's disease(Turkish Society of Cardiology, 2020) Taylan G.; Aktoz M.; Çelik M.; Yılmaztepe M.[No abstract available]Öğe Periprocedural cardiac troponin elevation: A potential indicator of enhanced ventricular threshold in permanent pacemaker recipients(Scientific Publishers of India, 2017) Uçar F.M.; Taylan G.; Yilmaztepe M.A.; Aktoz M.Background and aim: Permanent cardiac pacing is the most efficient treatment for patients with symptomatic bradycardia and high-degree atrioventricular (AV) block. For effective pacing, sensing and pacemaker battery longevity; ventricular pacing threshold (VPT) levels, lead impedance levels and R-wave amplitude levels must be desirable. We aimed to search the association between elevated serum troponin levels and VPT values in patients who has implanted single chamber permanent pacemaker. Materials and methods: We retrospectively analyzed a total of 109 patients (mean age: 78 ± 7.1 years, 53.6% male) who underwent single chamber permanent pacemaker implantation for indications such high-degree atrioventricular block and sick sinus syndrome. Hematological and biochemical parameters were measured prior to pacemaker implantation. Additionally troponin I and high-sensitivity C-reactive protein (hs-CRP) were sampled about 12 hours after pacemaker implantation. Results: Over a median follow-up period of 17.3 months, 32 (29.3%) patients has positive troponin I levels after implantation. Troponin positive group has higher VPT values at the time of implantation (0.94 ± 0.33 vs. 0.71 ± 0.19, p<0.001) and at 30th day of implantation (0.69 ± 0.16 V vs. 0.91 ± 0.31 V, p<0.001). To identify in dependent risk factors for ventricular threshold values, a multivariate linear regression model was conducted and after implantation having positive troponin value (?=0.337, p=0.01) and troponin elevation ratio (?=0.365, p<0.001) were found to be independent risk factors for ventricular threshold. Conclusion: Our results indicate that troponin I elevation after pacemaker implantation is associated with higher VPT values at the time of and the 30th day of implantation. For longevity of pacemaker batteries, low threshold values are preferable. To further extend the life of pacemakers, we recommend following patients more closely who has high troponin levels after permanent pace replacement. © 2017, Scientific Publishers of India.

This study aimed to determine the role of uric acid in predetermining coronary artery disease in youngpatients with acute myocardial infarction (AMI). Methods: This study included 80 of 1612 patients who applied our hospital between January 2000 and December 2005. All of the patients were under 35 years old, diagnosed with AMI by clinical and laboratory findings, and had coronary angiography. The study population was divided into two groups, the first having critical coronary artery disease (group I) and the second having normal coronary arteries (group II). Then we compared these groups with age, body mass index, risk factors, serum protein C, protein S, antithrombin III, creatinine and uric acid levels. Results: Myocardial infarction was located in 65% anterior, 15% inferior, 15% inferiolateral and 5% high lateral, respectively. Forty five % of patients had critical coronary artery disease (group I, n = 36) and 55% had normal coronary arteries (group II, n = 44). There were no differences in the two groups with regard to body mass index, family history, hypertension, smoking, cholesterol level, triglyceride level and creatinine level, lack of protein C, lack of protein S or lack of antithrombin Iff. Serum uric acid levels were found to be higher in group I (7.0 ± ± 1.4 mg/dL) than in group II (4.9 ± 1.1 mg/dL,- p = 0. 003). Conclusions: This study showed that high serum uric acid levels were associated with critical coronary artery disease in young patients (< 35 years) with AMI.
