    Heart Valve Disease Predict Mortality in Hemodialysis Patients: A Single Center Experience
    (2019) Ozelsancak, Ruya; Tekkarismaz, Nihan; Torun, Dilek; Micozkadioglu, Hasan; 0000-0002-0788-8319; 30421548
    Our aim is to investigate the clinical and laboratory findings affecting the mortality of the patients in 3 years follow-up who underwent hemodialysis at our center. In this retrospective, observational cohort study, 432 patients who underwent hemodialysis at our center for at least 5 months were included. The first recorded data and subsequent clinical findings of patients who died and survived were compared. Two hundred and ninety patients survived, 142 patients died. The mean age of the patients who died was higher (63.4 +/- 12.3 years, vs. 52 +/- 16.1 years, P = 0.0001), 60.5% of them had coronary artery disease (P = 0.0001), 93.7% of them had a heart valve disease. Duration of hemodialysis (survived 57 [21-260] months; died 44 [5-183] months, P = 0.000) was lower in patients who died. Serum potassium level before dialysis (5.1 +/- 0.6; 4.9 +/- 0.7 mEq/L, P = 0.030), parathyroid hormone (435 [4-3054]; 304 [1-3145] pg/mL, P = 0.0001), albumin (3.9 +/- 0.4; 3.8 +/- 0.4 mg/dL, P = 0.0001) and Kt/V (1.48 +/- 0.3; 1.40 +/- 0.3, P = 0.019) levels were lower, C-reactive protein (5[1-208]; 8.7[2-256] mg/L, P = 0.000) levels were higher in patients who died. Logistic regression analysis showed age (OR = 1.1), coronary artery disease (OR = 1.7) and more than one heart valve disease (OR = 2.4) are independent risk factors for mortality. Potassium level before dialysis (OR = 0.60), parathyroid hormone (OR = 0.99), and higher Kt/V (OR = 0.28) were found to be an advantage for survival. Age, coronary artery disease and especially pathology in more than one heart valve are risk factors for mortality. Heart valve problems might develop because of malnutrition and inflammation caused by the chronic renal failure.

    Preoperative Cardiac Risk Assessment in Renal Transplant Recipients: A Single-Center Experience
    (2019) Yilmaz, Kerem Can; Akgun, Arzu Neslihan; Ciftci, Orcun; Muderrisoglu, Haldun; Sezer, Siren; Moray, Gokhan; Haberal, Mehmet; 0000-0002-9635-6313; 29025386; AAG-8233-2020
    Objectives: Cardiovascular disease is the major cause of morbidity and mortality in patients on renal replacement therapy and in kidney transplant recipients. There are no specific recommendations for preoperative cardiac risk assessment before renal transplant. The aim of our study was to analyze preoperative cardiac test frequencies, test results, patient characteristics, and relations between cardiac stress test results and severe coronary artery disease. Materials and Methods: We retrospectively examined patients who underwent renal transplant between December 2011 and December 2016 in our hospital (Ankara, Turkey). Our study group included 216 patients. All patients had preoperative echocardiography. We recorded results of exercise stress tests, myocardial perfusion scintigraphy, and coronary angiography. For all patients, preoperative complete blood cell count, creatinine, high-density lipoprotein, triglycerides, low-density lipoprotein, and red cell distribution width values were obtained and recorded. Results: We classified patient groups according to presence or absence of severe coronary artery disease. Fourteen of 66 patients had severe coronary artery disease. In univariate analyses, age, having a history of familial coronary artery disease, diabetes mellitus, presence of coronary artery disease, and triglyceride levels were risk factors for severe coronary artery disease. In multivariate analysis, diabetes mellitus, presence of coronary artery disease, and having a history of familial coronary artery disease were statistically significant. Conclusions: Renal transplant recipients are a special patient population, and there must be specific suggestions for this population. If patients present with more than 1 risk factor, a stress test should be performed to evaluate cardiovascular risk. In some patients, especially those whose risk factors include prior cardiovascular disease or diabetes mellitus, stress tests should be skipped and patients should directly undergo coronary angiography to look for severe coronary artery disease.
