Öğe The effect of thyroid functions on contrast-induced nephropathy in patients undergoing coronary angiography and percutaneous coronary intervention(Pakistan Medical Assoc, 2019) Gurdogan, Muhammet; Ari, HasanObjective: To investigate the effects of thyroidism on the development of contrast-induced nephropathy in patients undergoing coronary angiography and percutaneous coronary intervention. Methods: The prospective, observational study was conducted at Trakya University Faculty of Medicine, Edirne, Turkey, from October 1, 2016, to October 1, 2017, and comprised patients with hypothyroidism, hyperthyroidism and euthyroid patients. Thyroid and renal functions were evaluated from blood samples taken before the procedure. The definition of contrast-induced nephropathy included absolute (0.5 mg/dL) or relative increase (25%) in serum creatinine 48-72 h after exposure to a contrast agent compared with baseline serum creatinine values. SPSS 10 was used for data analysis. Results: Of the 162 patients, 58(35.8%) had hypothyroidism, 47(29%) hyperthyroidism and 57(35.2%) euthyroid. Contrast-induced nephropathy was significantly higher in hypothyroid and hyperthyroid subjects compared to euthyroid group (p<0.001 each). Univariate analysis showed contrast volume, procedure, albumin value, hypothyroidism and hyperthyroidism to be independent predictors of contrast-induced nephropathy (p<0.05 each), but multivariate analysis only showed hypothyroidism and the hyperthyroidism as the independent predictors (p<0.01 each). Conclusion: Contrast-induced nephropathy rate was increased in patients with malfunctioning thyroid, Hypothyroidism and hyperthyroidism were found to be independent predictors of contrast-induced nephropathy.Öğe Levels of awareness of occupational and general cardiovascular risk factors among metal industry employees(Turkish Soc Cardiology, 2015) Gurdogan, Muhammet; Gurdogan, Eylem Pasli; Ari, Hasan; Erturk, Mehmet; Genc, Ahmet; Ucar, Mehmet FatihObjective: Long-term exposure to physical, chemical, ergonomic and psychosocial environmental factors may lead to occupational cardiovascular disease in metal industry employees. This study aimed to determine levels of knowledge levels regarding occupational and cardiovascular risk factors among metal industry employees. Methods: The study was conducted between 2nd and 6th June 2014 with the participation of 82 employees. All were working in a medium-sized workplace in the metal industry. Data were collected by means of a questionnaire, which included sociodemographic characteristics and occupational cardiovascular risk factors, and a scale developed by Arikan et al. to measure awareness levels of risk factors for cardiovascular diseases (CARRF-KL). Results: The mean age of employees was 39.97 +/- 8.44. Of the participants, 58.5% stated that they had knowledge on cardiac disease risk factors. The mean CARRF-KL score was found to be 18.65 +/- 4.04. The percentage of employees stating that they had no knowledge on the occupational risks for such diseases was 79.3%, while 19.5% stated that job stress caused cardiac diseases. One individual (1.2%) stated that one of the chemical solvents used in the working environment was a risk factor. Conclusion: Although awareness among metal industry employees of cardiovascular risk factors was above average, it was determined that they do not have adequate information on occupational risk factors. Prolonged and unprotected levels exposure to environmental factors constitute a risk for cardiovascular disease. This information is important for the development of preventive cardiology.Öğe Should Bioprosthetic Valves be Implanted in Patients with Aortic Stenosis having a Low Surgical Risk?
