    Effect of Post-Transplant Cardiac Angiographic Procedures on Post-Transplant Renal Function
    (2022) Keskin, Suzan; Ciftci, Orcun; Soy, Ebru Ayvazoglu; Muderrisoglu, Haldun; Haberal, Mehmet; 0000-0002-0993-9917; 0000-0002-3462-7632; 35918191; AAC-5566-2019; AAJ-8097-2021
    Background. Cardiac interventions often are performed before and after renal transplant for coronary artery disease. The aim of this study was to investigate whether post-transplant cardiac coronary procedures affect post-transplant renal function. Method. We retrospectively included renal transplant recipients who underwent renal transplant procedures at Baskent University between April 28, 1997 and January 20, 2020. We analyzed the effect of cardiac catheterization in renal transplant recipients between 6 and 12 months post-transplant with post-transplant renal function assessed by glomerular filtration rate (GFR). We compared the effect of the type of coronary intervention on GFR change in group 1, whereby group 1 was divided into 2 subgroups (coronary artery bypass grafting [CABG] and stenting). Group 1 included patients who underwent cardiac intervention, whereas group 2 included those who had not undergone cardiac intervention. Results. In all, 108 patients underwent coronary angiography; 45 (41.7%) had normal coronaries or minimal coronary artery disease (CAD); 37 (34.3%) underwent stent implantation; 26 (24.1%) underwent CABG. The mean post- transplantation GFR of all patients after cardiac catheterization was 84.26+25.91 (mL/min/1.73 m(2)). The final, after 12 months mean GFR of all patients was 69.55+27.05. The final GFR was significantly lower than the initial post-renal GFR value in patients who underwent cardiac intervention but not in non-intervened patients. Conclusion. Invasive cardiac revascularization procedures showed a negative effect on posttransplant renal function in renal transplant recipients. All renal transplant recipients who underwent cardiac intervention survived the intervention, and there was no mortality. The reason for this outcome was assumed to be because of the short follow-up period.

    Acute Coronary Syndrome In Geriatric Patients In An Intensive Care Unit
    (2021) Keskin, Suzan; Akgun, Arzu Neslihan; Ciftci, Orcun; Muderrisoglu, Ibrahim Haldun
    Objective: The advancing age of acute coronary syndrome and the ageing population are leading to an increase in the number of elderly patients with acute coronary syndrome in our clinical practice. In our study, we aimed to investigate the effect of acute coronary syndrome in the geriatric patient group. Materials and Method: We retrospectively included geriatric patients who were in intensive care units because of different diagnoses, who also showed an acute coronary syndrome, and who had been diagnosed using the sequential organ failure assessment score. This score is used to describe the condition of a patient with sepsis and the extent of organ damage during treatment in an intensive care unit. We reviewed patients who were at Baskent University Faculty of Medicine between 25 March 2015 and 12 March 2020. Results: We included 63 patients aged 77.27 +/- 7.65 years. There were 40 (63.5%) males and 23 (36.5%) females. A total of 42 (89.4%) patients died in the first 5 months, one (2.1%) died between the 6th and 10th months, two (4.3%) between the 11th and 20th months, and two (4.3%) between the 21st and 30th months. We found a significant relationship between the sequential organ failure assessment score and mortality rate (p<0.05). The sequential organ failure assessment score was reliable in predicting mortality in geriatric patients with acute coronary syndrome, with 57% sensitivity and 75% specificity. Conclusion: Mortality of geriatric patients with acute coronary syndrome can be significantly determined using the sequential organ failure assessment scores.

    The Effect of Renal Transplantation on Cardiac Functions
    (2020) Yilmaz, Kerem Can; Akgun, Arzu Neslihan; Keskin, Suzan; Ciftci, Orcun; Moray, Gokhan; Muderrisoglu, Haldun; Haberal, Mehmet; 0000-0002-3462-7632; 0000-0001-8926-9142; 33229768; AAJ-8097-2021; W-5233-2018; AAJ-1331-2021
    Chronic renal failure is a well-known risk factor for cardiovascular poor outcome. Despite advances in dialysis and renal transplantation, these patients still have high cardiovascular morbidity and mortality. The aim of our study was to evaluate the changes in blood parameters and echocardiographic parameters of patients undergoing renal transplantation in our center. One hundred and eighty-three patients who underwent renal transplantation between September 2012 and January 2016 were included in the study. Pre- and postoperative hemoglobin values, lipid profiles, ejection fractions, presence of left ventricular hypertrophy, presence of diastolic dysfunction, and valve pathologies were retrospectively scanned. Data were obtained from all patients in terms of blood parameters, but we compared 92 patients' echocardiographic data because of lack of both pre- and postoperative echocardiography records. In our study, 124 patients (67.8%) were male, and the mean age was 42.6 +/- 14.4 years. Hemoglobin levels (11.2 +/- 1.98, 12.7 +/- 2.2 mg/dL, P <0.001) and high-density lipoprotein (HDL) values (37.6 +/- 10.5, 46.6 +/- 13.6 mg/dL, P <0.001) were found to be different significantly. In echocardiographic evaluation, there was no difference between pre- and postoperative ejection fractions in 92 patients. However, patients with preoperative ejection fraction <50% had a significant increase in postoperative ejection fraction (40.1 +/- 6.2, 48.4% +/- 9.4%, P = 0.012). Renal transplantation can improve left ventricle ejection fraction in patients with basal ejection fraction less than 50% and also provide a significant increase in hemoglobin and HDL levels in all patients. This suggests that renal transplantation may reverse the process for dilated cardiomyopathy and may improve cardiac function in patients with low ejection fraction. However, transplantation should be performed as early as possible in these patients.
