(2023) Yildirir, Aylin; Turan, Sevgi; 0000-0001-8750-5287; 37288861; A-4947-2018
Background: Workplace-based assessment methods are essential in the assessment and evaluation of competency-based cardiology residency training. This study aims to deter- mine the assessment and evaluation methods used in cardiology residency training in Turkiye and to reach the opinions of the institutions on the applicability of the workplace-based assessments. Methods: In this descriptive study, a Google Survey was sent to the heads/trainers of resi- dency educational centers and their opinions about the currently used assessment and evaluation methods, applicability of cardiology competency exams, and the workplace-based assessments were asked. Results: Responses were received from 65 (76.5%) of 85 training centers. Of the centers, 89.2% reported using resident report cards, 78.5% case-based discussion, 78.5% direct observation of procedural skills, 69.2% multiple-choice questions, 60% traditional oral exams, and less commonly other exam types. About 74% of responders gave a positive opinion on the requirement of being successful in the Turkish Cardiology Competency knowledge exam before specialty. Case-based discussion was the most common work- place-based assessments that the centers think could be applied as suggested by the current literature. A common idea was the adaptation of workplace-based assessments based on international standards and our national norms. The trainers supported a nationwide examination for all training centers to ensure standardization. Conclusion: In Turkiye, it was promising to see that the trainers are positive about the applicability of workplace-based assessments, but they commonly thought that the pro- posed workplace-based assessments should be adapted before nationwide applicability. Medical educators and field experts need to work together on this issue. ORIGINAL

Aims: Contrast-induced nephropathy (CIN) is one of the most common causes of hospital-acquired acute renal failure. Oxidative stress and vasoconstriction might play key roles in its pathogenesis. In a few experimental models, antioxidant properties of carvedilol have been documented. The aim of this study was to analyze and compare the effects of carvedilol and metoprolol on the development of CIN in patients undergoing coronary angiography. Methods: One hundred patients currently taking metoprolol and 100 patients currently taking carvedilol were enrolled into the study. Venous blood samples were obtained before and 48 h after contrast administration. Cystatin C and malondialdehyde values were examined and compared. CIN was defined as a creatinine increase of at least 25% or 0.5 mg/dl from the baseline value. Results: Seven patients in the carvedilol group (7%) and 22 patients in the metoprolol group (22%) developed CIN (p = 0.003). In the metoprolol group, the median cystatin C concentration increased significantly from 978 to 1,086 ng/ml (p = 0.001) 48 h after radiocontrast administration. In the carvedilol group, the median cystatin C concentration did not change significantly (1,143 vs. 1,068 ng/ml; p = 0.94). In the metoprolol group, the mean malondialdehyde concentration increased significantly from 7.09 +/- 1.48 to 8.38 +/- 2.6 nmol/l (p < 0.001). In the carvedilol group, the mean serum malondialdehyde concentration did not change significantly (7.44 +/- 1.21 vs. 7.56 +/- 1.11 nmol/l; p = 0.59). Conclusion: When compared to metoprolol, carvedilol might decrease oxidative stress and subsequent development of CIN. (C) 2015 S. Karger AG, Basel

(2015) Altin, Cihan; Kanyilmaz, Suleyman; Koc, Sahbender; Gursoy, Yusuf Cemil; Bal, Ugur; Aydinalp, Alp; Yildirir, Aylin; Muderrisoglu, Haldun; 25502334
INTRODUCTION The incidence of coronary artery anomalies (CAAs) varies from 0.2% to 8.4%. Knowledge of such anatomical variations is important as coronary procedures are regularly performed these days. We aimed to find the coronary dominance pattern, intermediate artery (IMA) frequency and CAA incidence in our clinic, and compare them to those in the literature. METHODS The medical reports of 5,548 patients who had undergone coronary angiography (CAG) between 2005 and 2009 were retrospectively investigated. Dominance pattern and presence of IMA and CAA were recorded. CAAs were described using two different classifications: Angelini and Khatami's classification, and a new modified classification that was derived from Angelini and Khatami's classification. Some procedural details and clinical features of the patients with CAA were also investigated. RESULTS Coronary dominance pattern was: 81.6% right coronary artery, 12.2% circumflex artery and 6.2% co-dominant. IMA was present in 613 (11.0%) patients. The incidences of overall anomaly were 2.7% and 1.4%, according to the different classifications. Absent left main coronary artery, which was the most common anomaly in the present study, was found in 51 (0.9%) patients. Incidences of myocardial bridge, coronary arteriovenous fistulae and aneurysms were 1.1%, 0.2% and 0.3%, respectively. CONCLUSION CAAs are generally asymptomatic, isolated lesions. Some may lead to anginal symptoms, myocardial infarction or sudden death. We found that CAA was associated with increased radiation and contrast exposure in patients who underwent CAG. This risk could be reduced if appropriate catheters were designed and training programmes on ostial cannulation were developed.

Objective: Increased red blood cell distribution width (RDW) is associated with severity of coronary artery disease (CAD). The aim of the present study was to retrospectively evaluate the relationship between CAD detected by coronary computed tomography angiography (CCTA) and RDW. Methods: Records of 291 patients who underwent 16-slice CCTA due to the presence of angina-like chest pain were retrospectively evaluated. Exclusion criteria were applied. Clinical characteristics, risk factors for CAD, and RDW values on CCTA were noted. Results: RDW levels in patients with CAD were significantly higher than in those with normal coronary arteries (NCAs) (15.50 +/- 1.57 compared to 14.80 +/- 1.41, p=0.001). Diabetes mellitus, hypertension, and history of smoking were significantly more common in the CAD group (p=0.018, p=0.007, and p=0.013, respectively). On multivariate logistic regression analysis, RDW (p=0.009 [odds ratio (OR): 1.352; 95% confidence interval (CI): 1.081-1.683]), age (p<0.001 [OR: 1.063; 95% CI 1.031-1.090]), and history of smoking (p=0.003 [OR: 2.672; 95% CI: 1.360-5.232]) were shown to be independent predictors for CAD detected by CCTA. Conclusion: The present results suggest that higher RDW levels are independently associated with presence of CAD detected by CCTA in patients without known CAD. Further studies are warranted to clarify the exact role of RDW in risk stratification.

(2014) Bal, Ugur Abbas; Yildirir, Aylin; Aydinalp, Alp; Kaynar, Gamze; Kanyilmaz, Suleyman; Murat, Koza; Muderrisoglu, Ibrahim Haldun; https://orcid.org/0000-0002-9446-2518; https://orcid.org/0000-0001-8750-5287; https://orcid.org/0000-0002-3761-8782; 25233494; AAK-4322-2021; A-4947-2018; AAD-5841-2021
Objective: The aim of this study was to investigate the factors associated with coronary stent restenosis and if there is an association between plasma asymmetric dimethylarginine (ADMA) levels and stent restenosis. Methods: Ninety-one patients, who had a history of coronary bare metal stent implantation due to any cause in the last one year period, were admitted to this observational cross-sectional study. Coronary angiography was performed to all patients and quantitative angiography was used to determine the presence of stent restenosis. Laboratory parameters and angiographic features that contribute to stent restenosis were evaluated. Plasma ADMA levels were measured by using high performance liquid chromatography. Logistic regression analysis was used to determine the independent factors of stent restenosis. Results: Angiographic restenosis was found in 35 patients (38.5%). Stent diameter (p=0.038) and left ventricular ejection fraction (p=0.023) were lower and stent implantation history due to acute coronary syndrome (p=0.029), plasma ADMA level (5.0 +/- 1.8x10(-4) mmol/L vs. 3.9 +/- 1.0x10(-4) mmol/L, p=0.001), C-reactive protein concentration (p=0.016), white blood cell count (p=0.044) and stent length (p=0.005) were higher in patients with restenosis. Plasma ADMA level (beta=0.536; OR: 1.710; CI: 1.022-2.861; p=0.041), C-reactive protein concentration (beta=0.062; OR: 1.064; CI: 1.003-1.129; p=0.041), stent diameter (beta=-3.047; OR: 0.048; CI: 0.007-0.313; p=0.002) and length (beta=0.165; OR: 1.179; CI: 1.036-1.343; p=0.013) were found to be the independent predictors of stent restenosis in logistic regression analysis. Conclusion: We conclude that plasma ADMA levels may be used as a novel marker for stent restenosis beyond the classic stent restenosis markers.

(2015) Bal, Ugur Abbas; Atar, Ilyas; Oktem, Mesut; Zeyneloglu, Hulusi Bulent; Yildirir, Aylin; Kuscu, Esra; Muderrisoglu, Haldun; 25430415
Objective: In healthy women, there is a progressive age-related increase in myocardial mass that is not seen in their male counterparts and occurs primarily in postmenopausal women. Raloxifene is a selective estrogen receptor modulator that has estrogenic actions on bone and the cardiovascular system. The aim of this study was to investigate the effect of raloxifene on myocardial hypertrophy in postmenopausal patients. Methods: A total of 22 postmenopausal osteoporotic women were included in this open-label, randomized, prospective, controlled study. Patients were randomized into two groups: 11 of the patients (group 1) were treated with raloxifene 60 mg/day, and the other 11 patients (group 2) were defined as the control group. Quantitative 2-dimensional and M-mode echocardiographic examination was performed in all patients at the beginning and repeated at the end of the 6-month follow-up period. Left ventricle mass (LVM) and left ventricle mass index (LVMI) were calculated for all patients. Results: The mean age of the patients was 57.2 +/- 3.9 years, and baseline clinical characteristics and echocardiographic parameters were similar between the two groups. After 6 months of raloxifene treatment, there was no difference in echocardiographic parameters of LVM and LVMI compared with the control group (201.2 +/- 25.9 gr vs. 169.7 +/- 46.2 gr, p=0.14 and 120.4 +/- 25.9 gr/m(2) vs. 105.5 +/- 26.3 gr/m(2), p=0.195, respectively). There was also no significant difference in LVM and LVMI in the within-group analysis of both groups. Conclusion: Raloxifene therapy does not affect myocardial hypertrophy in postmenopausal women after 6 months of treatment.
Effects of Short Term Mild L-Thyroxine Suppression Therapy on Myocardial Functions, and Its Assessment with Tissue Doppler Imaging
(2016) Bozkus, Yusuf; Sunger, Ahmet; Yildirir, Aylin; Bascil Tutuncu, Neslihan; 0000-0001-8750-5287; 0000-0002-6976-6659; 0000-0002-1816-3903; 25389951; A-4947-2018; AAA-5419-2021; ABG-5027-2020
BACKGROUND: While adverse effects of overt hyperthyroidism on the cardiovascular system are well-known, the effects of subclinical hyperthyroidism are not clear. The aim of the study was to investigate the effects of short term mild L-thyroxine (LT4) suppression therapy on myocardial functions in a group of premenopausal women with goiter, by using echocardiographic methods and tissue Doppler imaging (TDI). METHODS: Sixteen participants with goiter received LT4 suppression therapy to keep TSH levels between 0.1-0.4 mu IU/mL. After baseline and 1st month assessment, 6-weeks follow-up were scheduled until 6th month assessment to adjust the medication dose during study period. All TSH levels decreased below 0.4 mu IU/mL by the end of first month and stayed below this level throughout study period. At the beginning of the study and at month 6, the thyroid ultrasonography, Holter monitorization test, stress test, electrocardiograms and echocardiograms of participants were assessed. This was followed by a comparison of baseline and 6th month data. RESULTS: Baseline and 6th month 2-D echocardiography measurements of participants revealed that mean left ventricle diameter in diastole (4.1 +/- 0.3 vs 3.8c0.2 mm) and posterior wall thickness in diastole (0.9 +/- 0.1 vs. 0.8 +/- 0.1 mm) decreased (P<0.05); while stroke volume (41.9 +/- 9.9 vs. 48 +/- 8.2), stroke volume index (25.6 +/- 5.4 vs. 29.4 +/- 4.7), cardiac output (3.5 +/- 1.4 vs. 3.9 +/- 0.9) and cardiac index (2.2 +/- 0.8 vs. 2.4 +/- 0.5) increased (P<0.05). Other 2D echocardiography parameters did not change significantly. The pulse wave Doppler examination, stress test and Holier monitorization of participants did not reveal any difference between baseline and 6th month measurements. No statistically significant difference was observed in measurements of TDI except decreased septum S velocity. CONCLUSIONS: Short term mild LT4 suppression treatment did not cause systolic or diastolic dysfunction, or conduction defect in the heart; therefore may be safe in premenopausal females with not known cardiac disease.

(2015) Bal, Zeynep; Bal, Ugur; Okyay, Kaan; Yilmaz, Mustafa; Balcioglu, Serhat; Turgay, Ozge; Hasirci, Senem; Aydinalp, Alp; Yildirir, Aylin; Sezer, Siren; Muderrisoglu, Haldun; 0000-0002-8342-679X; 0000-0001-6134-8826; 0000-0002-6731-4958; 0000-0002-9635-6313; 0000-0002-3761-8782; 0000-0002-9446-2518; 0000-0001-8750-5287; 0000-0002-2557-9579; 26246038; AAK-7805-2021; AAK-7355-2020; GPX-1387-2022; AAG-8233-2020; AAD-5841-2021; AAK-4322-2021; AAZ-5795-2021; A-4947-2018; S-6973-2016
Aside from traditional factors (e.g., diabetes, age, and hypertension), some hematological parameters, such as neutrophil-to-lymphocyte ratio (NLR), red blood cell distribution width (RDW), and mean platelet volume (MPV), have increasingly been reported as measures of systemic inflammation and atherosclerosis in patients with end-stage renal disease (ESRD). This study aimed to determine whether there is an association between these hematological parameters and the extent of coronary artery disease (CAD) in patients with ESRD. A total of 149 consecutive ESRD patients (66 % males) without established CAD were studied. NLR, RDW, and MPV values in all patients were calculated from the complete blood count before coronary angiography. Angiographic views were assessed by an experienced interventional cardiologist, and the extent of CAD was evaluated by the Gensini score. The patients were divided into quartiles of the Gensini score. Age, time on dialysis, calcium-phosphorus product, C-reactive protein levels, NLR, and MPV were significantly different among the groups (all p < 0.05). The Gensini score was correlated with age, time on dialysis (both p < 0.001), NLR (p = 0.004), and C-reactive protein levels (p = 0.034) and inversely correlated with left ventricular ejection fraction (p = 0.023). Multivariate regression analysis showed that age (p = 0.001), time on dialysis (p < 0.001), NLR (p = 0.001), and MPV (p = 0.005) were independent predictors of the extent of CAD. Aside from the well-known traditional factors, NLR and MPV are independent predictors of the extent of CAD in patients with ESRD.
Is there a relationship between resistin levels and left ventricular end-diastolic pressure?
(2018) Yildirir, Aylin; Yildirim, Ozge Turgay; Sade, Leyla Elif; Hasirci, Senem Has; Kozan, Hatice; Ozcalik, Emre; Okyay, Kaan; Bal, Ugur Abbas; Aydinalp, Alp; Muderrisoglu, Haldun; 0000-0002-9635-6313; 0000-0002-6731-4958; 29615544; AAK-7355-2020; AAG-8233-2020
Objective: Resistin, a cysteine-rich peptide, is associated with atherosclerosis and diabetes. Resistin levels increase corresponding to coronary artery disease (CAD) and heart failure severity. Since resistin level tends to elevate with symptomatic heart failure, it is expected to be associated with left ventricular end-diastolic pressure (LVEDP). However, there is no relevant literature on the relationship between resistin levels and LVEDP. We aimed to evaluate the association between resistin levels and LVEDP, severity of CAD, carotid intima-media thickness (CIMT), and echocardiographic diastolic dysfunction parameters. Methods: For this study, 128 euvolemic patients with creatinine clearance >50 mg/dL and without acute coronary syndrome, who had typical chest pain or were stress test positive, were enrolled. Resistin level was measured by Enzyme-linked immunosorbent assays (ELISA) method. Severe CAD is defined as >= 50% stenosis in one of the major coronary arteries. LVEDP was measured during left heart catheterization. Results: After coronary angiography, 60 patients (46.9%) had severe CAD. The mean LVEDPs were similar for patients with and without severe CAD (p=0.480). The resistin levels did not differ between the groups (p=0.154). The resistin levels did not correlate with LVEDP (r=-0.045, p=0.627), ejection fraction (EF; r=0.110, p=0.228), the Gensini score (r=-0.091, p=0.328), and CIMT (r=0.082, p=0.457). No significant correlation was found between the echocardiographic diastolic dysfunction parameters and resistin levels. Conclusion: There was no significant correlation between resistin level and LVEDP, CAD severity, echocardiographic diastolic dysfunction parameters, and CIMT. Further studies are warranted to determine the efficacy of resistin in clinical use.
Learning in the Digital Age: E-Learning in Cardiology Specialization Training
(2020) Altun, Armagan; Yildirir, Aylin; 0000-0002-3233-8263; ABB-5844-2020
Digital cardiologists are cardiologists who can use digital media in clinical practice, education, and interaction with patients. Although digital tools are supportive of education, they cannot replace human thoughts and feelings. On the other hand, it is useful to arrange the core training program of cardiology in a way to train digital cardiologists of the future. Educators lacking this opportunity during their training should adapt quickly to e-learning. Blended use of e-learning and face-to-face learning seems to be the most effective way. in this way, the trainer will transfer his experiences on one hand and on the other hand, he will enable the learner to acquire lifelong learning habit by supporting the self-learning activity with the e-learning opportunities.

(2018) Yilmaz, Kerem Can; Bal, Ugur Abbas; Karacaglar, Emir; Okyay, Kaan; Aydinalp, Alp; Yildirir, Aylin; Muderrisoglu, Haldun; 0000-0002-2538-1642; 0000-0002-9446-2518; 0000-0002-9635-6313; 0000-0002-3761-8782; 0000-0001-8750-5287; 0000-0001-6134-8826; 0000-0003-3320-9508; 28841817; ABI-6723-2020; AAJ-1331-2021; AAK-4322-2021; AAG-8233-2020; AAD-5841-2021; A-4947-2018; AAK-7355-2020
Objective: Osteopontin is a component of atherosclerotic lesions, secreted by monocytes, macrophages and endothelial and vascular smooth muscle cells, which together are responsible for neointimal proliferation. We examined whether elevated plasma osteopontin concentration was associated with in-stent restenosis in patients with coronary artery disease. Subjects and methods: We enrolled 91 patients who underwent coronary artery stenting, and 60 control patients with normal findings on coronary angiography, between June 2012 and September 2013. For patients with stents, we measured plasma osteopontin concentration at the first follow-up coronary angiogram. For controls, plasma osteopontin concentration was measured at the time of angiography. Results: Of the 91 patients who had undergone coronary artery stenting, 31 (34.1%) had developed in-stent restenosis and the mean time passed to control coronary angiography was 36.7 months (+/- SD 35.1 months). Mean plasma osteopontin concentration in this group was 2721.4 +/- 1787.8 pg/ml, significantly higher than the 60 patients (65.9%) with no in-stent restenosis (1770.4 +/- 1208.2 pg/ml, p = .011) and the 60 patients with a normal coronary angiogram (1572.4 +/- 904.8 pg/ml, p = .002). There was no significant difference in mean osteopontin concentration between the patients with no in-stent restenosis and the control group (p = .312). Conclusions: Elevated plasma osteopontin concentration is associated with in-stent stenosis in patients with coronary artery disease. Further studies will be needed to establish whether osteopontin can predict in-stent restenosis and guide clinical management strategies.
Platelet Membrane Gamma-Glutamyl Transferase-Specific Activity and the Clinical Course of Acute Coronary Syndrome
(2019) Demirtas, Koray; Yayla, Cagri; Sade, Leyla Elif; Yildirir, Aylin; Ozin, Mehmet Bulent; Haberal, Aysegul; Muderrisoglu, Ibrahim Haldun; 0000-0001-8750-5287; 29996664; A-4947-2018
gamma-Glutamyl transferase (GGT) participates in oxidative and inflammatory reactions inside the atheroma plaque and platelets. We evaluated whether platelet membrane gamma-glutamyl transferase (Plt-GGT) activity is a predictor of major adverse cardiac events (MACEs) during 3 months follow-up of patients with acute coronary syndrome (ACS; MACE-3M). We included 105 patients who were hospitalized consecutively with the diagnosis of ACS. Patients with an MACE-3M were older, more likely to have hypertension, hyperlipidemia, family history of coronary artery disease(CAD), thrombolysis in myocardial infarction (TIMI) risk score >4, higher Plt-GGT and serum GGT activities, serum C-reactive protein level, and lower left ventricular ejection fraction (LVEF) when compared to those without MACE-3M (all P values <=.05). By receiver-operator characteristic (ROC) curve analysis, 265 mU/mg for Plt-GGT, 30 U/L for serum GGT, and 45% for LVEF were determined as cutoff values to discriminate MACEs. Platelet GGT activity >265 mU/mg, TIMI risk score >4, and family history of CAD were independent predictors of MACE-3M (all P values <.05). Platelet GGT activity was as an independent predictor for MACEs in patients with ACS during the 3 months follow-up.
