Article Citation - WoS: 1Citation - Scopus: 2Association Between the Triglyceride-Glucose Index and Contrast-Induced Nephropathy in Chronic Total Occlusion Patients Undergoing Percutaneous Coronary Intervention(Bmc, 2025) Soner, Serdar; Aktan, Adem; Kilic, Raif; Guzel, Hamdullah; Tastan, Ercan; Oksul, Metin; Guzel, TuncayObjective The triglyceride glucose (TyG) index is a biomarker of insulin resistance and is associated with an increased risk of cardiovascular events. Contrast-induced nephropathy (CIN) is an important complication that causes poor outcomes in patients undergoing percutaneous coronary intervention (PCI). In this study, we aimed to investigate the relationship between the TyG index and CIN and mortality in patients who underwent PCI due to chronic total coronary occlusion (CTO). Methods Two hundred eighteen individuals from three separate medical centers who underwent procedural PCI between February 2010 and April 2012 and had a CTO lesion in at least one coronary artery were recruited. According to the TyG index, patients were divided into two groups. Patients with a TyG index >= 8.65 were included in Group 1, and patients with a TyG index < 8.65 were included in Group 2. Patients were followed up for 96 months. The main outcome was the development of CIN and mortality. Results The mean age of the patients (65.8 +/- 10.94 vs. 61.68 +/- 11.4, P = 0.009), diabetes mellitus (60 [44.8%] vs. 11 [13.1%], P < 0.001), and dyslipidemia rates (52 [38.8%] vs. 21 [25%], P = 0.036) were higher in group 1. In multivariable logistic regression analysis, it was seen that age (OR = 1.04, 95% CI = 1.01-1.08, P = 0.020), chronic kidney disease (OR = 2.34, 95% CI = 1.02-5.33, P = 0.044), peripheral artery disease (OR = 5.66, 95% CI = 1.24-25.91, p = 0.026), LVEF (OR = 0.95, 95% CI = 0.92-0.99, P = 0.005), LDL cholesterol levels (OR = 1.00, 95%CI = 1.00-1.02, P = 0.024) and TyG index (OR = 2.17, 95% CI = 1.21-3.89, P = 0.009) were independent predictors of the development of CIN. Conclusion Our study demonstrates a correlation between the TyG index and the prevalence of CIN in patients with CTO undergoing PCI. Adding the TyG index to the routine clinical evaluation of patients with CTO undergoing PCI may help protect patients from the development of CIN.Article Citation - WoS: 1Citation - Scopus: 1Ability of Cha2ds2-vasc/R2cha2ds2-vasc Scores To Predict Complications Related To Cardiac Implantable Electronic Devices(Wiley, 2025) Aktan, Adem; Kilic, Raif; Guzel, Hamdullah; Tastan, Ercan; Oksul, Metin; Guzel, Tuncay; Soner, SerdarBackgroundGlobally, the number of cardiac implantable electronic devices (CIEDs) is increasing. In our study, we aimed to investigate whether CHA(2)DS(2)-VASc and R(2)CHA(2)DS(2)-VASc scores are predictive of CIED-related complications. MethodsOur investigation was carried out with a multicenter retrospective design. Patients who underwent CIED surgery at two cardiac centers in Turkey between January 2011 and May 2023, 1676, were evaluated. The patients were divided into two groups according to their R(2)CHA(2)DS(2)-VASc scores. Patients with R(2)CHA(2)DS(2)-VASc >= 5 were included in group 1 (380 patients), and patients with R(2)CHA(2)DS(2)-VASc < 5 (1296 patients) were included in group 2. The primary outcome was defined as the cumulative events. Each component of cumulative events, such as hematoma, pericardial effusion, pneumothorax, and infection, was also defined as a secondary outcome. ResultsThe study's patient population had an average age of 62.9 +/- 14 years. Pneumothorax (1.8% vs. 1.3%, p = 0.444), pericardial effusion or tamponade (0.35% vs. 0.2%, p = 0.659), and clinically significant hematoma (1.1% vs. 0.6%, p = 0.376) were comparable between the groups. Infection-related devices and cumulative events classified as primary outcomes were higher in the R(2)CHA(2)DS(2)-VASc >= 5 group (6.1% vs. 1.2%, p < 0.001; 7.6% vs. 3.2%, p < 0.001, respectively). Modeling analyses showed that the CHA(2)DS(2)-VASc score and HT were also independent predictors of device-related infection and cumulative events. ConclusionIn the R(2)CHA(2)DS(2)-VASc >= 5 groups, infection related to the device system and cumulative events were higher. Patients with an R(2)CHA(2)DS(2)-VASc score of 5 or more and a high CHA(2)DS(2)-VASc score should be evaluated more carefully regarding infection and cumulative events before and after the operation.Article Impact of 5-and 6-Fr Sheaths on Hemostasis Duration and Access Site Complications in Distal Transradial Approach(Wiley, 2025) Aktan, Adem; Kilic, Raif; Guzel, Tuncay; Evsen, Ali; Acun, Baris; Tanircan, Muhammed Rasit; Karahan, Mehmet ZulkufBackground: The distal transradial approach (dTRA) is increasingly preferred for coronary angiography (CAG) and/or per-cutaneous coronary intervention (PCI) because of its advantages in patient comfort and vascular access. However, the effect of sheath size on these outcomes remains unclear.
Aim: To compare the effects of 5-French (Fr) and 6-Fr sheaths in dTRA on vascular complications, hemostasis duration, and patient comfort.
Methods: A retrospective analysis was conducted on patients who underwent dTRA for CAG between January 2020 and October 2023. Participants were categorized into two groups based on sheath size (5- vs. 6-Fr). Data on procedural details, complications, hemostasis duration, and patient discomfort were collected.
Result: A total of 228 patients were included, with 72 in the 5-Fr group and 156 in the 6-Fr group. The study found no significant difference in vascular complications between the two groups (p = 0.18). However, hemostasis duration was significantly shorter in the 5-Fr group compared to the 6-Fr group (97.8 +/- 27.6 vs. 122.0 +/- 24.9 min; p < 0.001). Severe pain was more frequent in the 6-Fr group (p = 0.036). Regression analysis showed that severe pain, puncture time, and the use of P2Y12 receptor antagonists (P2Y12 inhibitors) were significantly associated with vascular complications (p < 0.05).
Conclusion: In our study, sheath size-specifically the comparison between 5- and 6-Fr-did not significantly affect vascular complications in the dTRA. However, using a 5-Fr sheath may reduce hemostasis time and patient discomfort compared to a 6-Fr sheath. Procedural factors such as puncture time and severe pain, as well as P2Y12 inhibitor use, should be carefully considered to minimize complications. These findings support the safe application of the dTRA with sheath size tailored to individual patient characteristics.Article Response to Comment Letter: The Effectiveness of HALP Score in Predicting Mortality in Non-ST Myocardial Infarction Patients(Lippincott Williams & Wilkins, 2025) Kiliç, R.; Aktan, A.; Guzel, T.Article Citation - WoS: 2Citation - Scopus: 2The Effect of Aortic Angulation on Clinical Outcomes of Patients Undergoing Transcatheter Aortic Valve Replacement(Soc Brasil Cirurgia Cardiovasc, 2024) Aktan, Adem; Demir, Muhammed; Aslan, Burhan; Guzel, Tuncay; Karahan, Mehmet Zulkuf; Kilic, Raif; Ertas, FarukIntroduction: The aim of this study was to assess the impact of aortic angulation (AA) on periprocedural and in -hospital complications as well as mortality of patients undergoing Evolut (TM) R valve implantation. Methods: A retrospective study was conducted on 264 patients who underwent transfemoral-approach transcatheter aortic valve replacement with self-expandable valve at our hospital between August 2015 and August 2022. These patients underwent multislice computer tomography scans to evaluate AA. Transcatheter aortic valve replacement endpoints, device success, and clinical events were assessed according to the definitions provided by the Valve Academic Research Consortium -3. Cumulative events included paravalvular leak, permanent pacemaker implantation, new-onset stroke, and in -hospital mortality. Patients were divided into two groups, AA <= 48(degrees) and AA > 48(degrees), based on the mean AA measurement (48.3 +/- 8.8) on multislice computer tomography. Results: Multivariable logistic regression analysis was performed to identify predictors of cumulative events, utilizing variables with a P-value < 0.2 obtained from univariable logistic regression analysis, including AA, age, hypertension, chronic renal failure, and heart failure. AA (odds ratio [OR]: 1.73, 95% confidence interval [CI]: 0.89-3.38, P=0.104), age (OR: 1.04, 95% CI: 0.99-1.10, P=0.099), hypertension (OR: 1.66, 95% CI: 0.82-3.33, P=0.155), chronic renal failure (OR: 1.82, 95% CI: 0.92-3.61, P=0.084), and heart failure (OR: 0.57, 95% CI: 0.27-1.21, P=0.145) were not found to be significantly associated with cumulative events in the multivariable logistic regression analysis. Conclusion: This study demonstrated that increased AA does not have a significant impact on intraprocedural and periprocedural complications of patients with new generation self-expandable valves implanted.Article Citation - WoS: 3Citation - Scopus: 3The prognostic value of ORBIT risk score in predicting major bleeding in patients with acute coronary syndrome(ScienceDirect, 2023) Günlü, Serhat; Arpa, Abdulkadir; Kayan, Fethullah; Güzel, Tuncay; Kılıç, Raif; Aktan, Adem; Altintaş, Bernas; Karahan, Mehmet ZülkifBackground: The most significant adverse effect of antithrombotic medication in acute coronary syndrome (ACS) is major bleeding, which is related to increased mortality. Studies on ORBIT risk score in predicting major bleeding in ACS patients are limited. Objective: This research aimed to examine whether the ORBIT score calculated at the bedside can identify major bleeding risk in patients with ACS. Methods: This research was retrospective, observational, and conducted at a single center. Analyses of receiver operating characteristics (ROC) were utilized to define the diagnostic value of CRUSADE and ORBIT scores. The predictive performances of the two scores were compared using DeLong's method. Discrimination and reclassification performances were evaluated by the integrated discrimination improvement (IDI), and net reclassification improvement (NRI). Results: The study included 771 patients with ACS. The mean age was 68.7 ± 8.6 years, with 35.3 % females. 31 patients had major bleeding. Twenty-three of these patients were BARC 3 A, five were BARC 3 B, and three were BARC 3 C. Bleeding history [OR (95 % CI), 2.46 (1.02-5.94), p = 0.021], hemoglobin levels [OR (95 % CI), 0.54 (0.45-0.63), p < 0.001], and age > 74 years [OR (95 % CI), 1.03 (1.01-1.06), p = 0.039] were independent predictors of major bleeding. The ORBIT score was an independent predictor of major bleeding in the multivariate analysis: continuous variables [OR (95 % CI), 2.53 (2.61-3.95), p < 0.001] and risk categories [OR (95 % CI), 3.06 (1.69-5.52), p < 0.001]. Comparison of c-indexes for major bleeding events revealed a non-significant difference for the discriminative ability of the two tested scores (p = 0.07) with a continuous NRI of 6.6 % (p = 0.026) and an IDI of 4.2 % (p < 0.001). Conclusion: In ACS patients, the ORBIT score independently predicted major bleeding.Article The Role of Statins in Modulating Subclinical Inflammatory Markers in Coronary Slow Flow Phenomenon(Lippincott Williams & Wilkins, 2025) Demirci, Murat; Mustafayev, Urfan; Atas, Halil; Oguz, Mustafa; Kilic, Raif; Sunbul, MuratCoronary slow flow phenomenon (CSFP) is characterized by slow coronary blood flow in the absence of significant stenosis, and its pathophysiology is associated with endothelial dysfunction, microvascular abnormalities, and inflammation. This study aimed to investigate the effects of statin therapy on subclinical inflammatory markers in CSFP patients. This retrospective cohort study included patients diagnosed with CSFP by using coronary angiography. The patients were divided into statin and control groups based on the initiation of statin therapy. Inflammatory markers, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and systemic inflammation response index (SIRI) were assessed at baseline and 3 months later. At baseline, NLR, PLR, SII, and SIRI levels were comparable between the 2 groups. After 3 months, these markers were significantly lower in the statin group. In the statin group, the NLR, PLR, SII, and SIRI levels significantly decreased from baseline, whereas no significant changes were observed in the control group. The reduction in inflammatory marker levels was more pronounced in patients receiving high-dose statins. Statin therapy is associated with reduced subclinical inflammation in CSFP, supporting the inflammatory basis and therapeutic value of statins.Article Citation - WoS: 3The prognostic value of ORBIT risk score in predicting major bleeding in patients with acute coronary syndrome(ELSEVIER, 2023) Günlü, Serhat; Arpa, Abdulkadir; Kayan, Fethullah; Güzel, Tuncay; Kılıç, Raif; Aktan, Adem; Bernas, Altıntaş; Karahan, Mehmet ZülkifBackground: The most significant adverse effect of antithrombotic medication in acute coronary syndrome (ACS) is major bleeding, which is related to increased mortality.

PCI sonrasında, kontrast kaynaklı nefropati (CIN) sık rastlanan bir komplikasyon olup artmış morbidite ve mortaliteye katkıda bulunmaktadır. Ürik asit-albumin oranı (UAR), son dönemde olumsuz klinik sonuçlarla ilişkili yeni bir biyobelirteç olarak tanımlanmıştır. Bu çalışma, CTO hastalarında UAR’ın CIN ve uzun dönem mortalite açısından prognostik önemini belirlemeyi amaçlamıştır. Yöntemler: Bir veya daha fazla CTO lezyonu nedeniyle PCI uygulanan toplam 169 hasta retrospektif olarak değerlendirildi. Hastalar, CIN gelişimine göre iki gruba ayrıldı: CIN-pozitif (n = 27) ve CIN-negatif (n = 142). Bulgular: CIN (+) grubu, CIN (−) grupla karşılaştırıldığında anlamlı şekilde daha yüksek serum ürik asit düzeyleri, daha yüksek UAR değerleri ve artmış mortalite oranları gösterdi (tümü p < 0,001). Ayrıca, çok değişkenli regresyon analizi UAR’ı CIN için bağımsız bir prognostik gösterge olarak ortaya koydu (p = 0,012). UAR için 1,77 kesme değeri CIN’i %66,7 duyarlılık ve %62 özgüllük ile öngörürken, 1,90 kesme değeri uzun dönem mortaliteyi %64,5 duyarlılık ve %73,9 özgüllük ile tahmin etti. Kaplan–Meier sağkalım eğrilerine göre, CIN-pozitif gruptaki bireyler uzun dönem sağkalım açısından belirgin şekilde daha düşük ve tüm nedenlere bağlı ölüm sıklığı açısından daha yüksek bulundu (log-rank, p < 0,001). Sonuç: Artmış UAR, CTO hastalarında hem CIN’i hem de uzun dönem mortaliteyi bağımsız olarak öngörmüş olup, bu yüksek riskli popülasyonda prognostik önemini vurgulamaktadır.Article Citation - WoS: 2Evaluation of Hematological Parameters After Transcatheter Aortic Valve Replacement(SAGE, 2023) Karahan, Mehmet Zülkif; Aktan, Adem; Güzel, Tuncay; Kılıç, Raif; Günlü, Serhat; Demir, Muhammed; Ertaş, FarukAlthough transcatheter aortic valve replacement (TAVR) is safe and effective, mortality and bleeding events post procedure are important. The present study investigated the changes in hematologic parameters to evaluate whether they predict mortality or major bleeding. We enrolled 248 consecutive patients (44.8% male; mean age 79.0 ± 6.4 years) undergoing TAVR. In addition to demographic and clinical examination, blood parameters were recorded before TAVR, at discharge, 1 month and 1 year. Hemoglobin levels before TAVR 12.1 ± 1.8 g/dL, 10.8 ± 1.7 g/dL at discharge, 11.7 ± 1.7 g/dL at first month, 11.8 ± 1.4 g/dL at first year (Hemoglobin values compared with pre-TAVR, P < .001, P = .019, P = .047, respectively). Mean platelet volume (MPV) before TAVR 8.72 ± 1.71 fL, 8.16 ± 1.46 fL at discharge, 8.09 ± 1.44 fL at first month, 7.94 ± 1.18 fL at first year (MPV values compared with pre-TAVR, P < .001, P < .001, P < .001, respectively). Other hematologic parameters were also evaluated. Hemoglobin, platelet count, MPV, and red cell distribution width before the procedure, at discharge, and at the first year did not predict mortality and major bleeding in receiver operating characteristic analysis. After multivariate Cox regression analysis, hematologic parameters were not independent predictors of in-hospital mortality, major bleeding, and death at 1 year after TAVR.
