(Polish Cardiac Soc, 2022) Cinar, Tufan; Saylik, Faysal; Akbulut, Tayyar; Asal, Suha; Selcuk, Murat; Cicek, Vedat; Orhan, Ahmet Lutfullah
Background: Prior studies showed that patients with elevated whole blood viscosity (WBV) had a higher risk of arterial thrombosis, acute stent thrombosis, and left ventricular apical thrombus presence after acute coronary syndrome. This investigation aimed to determine the association between WBV and high thrombus burden (HTB) in non-ST elevation myocardial infarction (NSTEMI) patients treated with percutaneous coronary intervention (PCI). Methods: This retrospective cohort investigation included data from consecutive 290 NSTEMI patients who received PCI at a tertiary institution. Patients with grade 1-3 thrombus burden were categorized as having low thrombus burden (LTB) (n = 178), whereas those with grade 4-5 thrombus burden were classified as having HTB (n = 112). WBV at high shear rate (HSR) and low shear rate (LSR) were estimated using hematocrit (HTC) and total protein levels. Results: Patients with HTB had higher WBV at both LSR and HSR. In HTB patients, the frequency of infarct-related artery (IRA) reference vessel diameter, distal embolization, and no-reflow was also higher. Multivariable logistic regression models indicated that WBV at LSR (odds ratio [OR], 1.028; 95% confidence interval [CI], 1.014-1.043; P < 0.001) and HSR (OR, 1.606; 95% CI, 1.334-1.953; P < 0.001) were independent predictors of HTB in NSTEMI patients. Notably, the area under the curve value of WBV at both shear rates was greater than that of its components, including total protein and HTC. Conclusion: This is the first study showing that WBV at both shear rates is a significant predictor of HTB in NSTEMI patients.

(Sage Publications inc, 2022) Selcuk, Murat; Cinar, Tufan; Saylik, Faysal; Demiroz, Onder; Yildirim, Ersin
This study aimed to evaluate the association of admission PREdicting bleeding Complications In patients undergoing Stent implantation and subsEquent Dual Anti Platelet Therapy (PRECISE-DAPT) score with the development of no-reflow (NR) in patients with ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). In this observational, retrospective study, 335 consecutive STEMI patients who were treated with primary PCI were included. We classified the study population into 2 groups: patients with a PRECISE-DAPT score <25 and those with a PRECISE-DAPT score >= 25. Overall, 30 (8.9%) patients developed NR. The mean PRECISE-DAPT score (20.03 +/- 15.32 vs 11.33 +/- 12.18; P = .005) was significantly higher in cases who developed NR. Moreover, arrhythmic complications, in-hospital shock, and in-hospital mortality rates were significantly higher in patients with a PRECISE-DAPT score >= 25 compared to those with a PRECISE-DAPT score <25. According to a multivariable analysis, the PRECISE-DAPT score was found to be independently linked with NR (odds ratio: 2.87, with P = .015). To our knowledge, these data are the first in major medical science databases to determine the relationship between the PRECISE-DAPT score and the NR phenomenon in patients with STEMI undergoing primary PCI.
The Association of Serum Uric Acid/Albumin Ratio With No-Reflow in Patients With St Elevation Myocardial Infarction
(Sage Publications inc, 2023) Cinar, Tufan; Saylik, Faysal; Hayiroglu, Mert Ilker; Asal, Suha; Selcuk, Murat; Cicek, Vedat; Tanboga, Ibrahim Halil
The goal of this investigation was to explore the relationship between serum uric acid/albumin ratio (UAR) and no-reflow (NR) in ST elevation myocardial infarction (STEMI) patients (n = 838) who underwent primary percutaneous coronary intervention (pPCI). Angiographic NR was defined as thrombolysis in myocardial infarction (TIMI) flows 0, 1, and 2 in the absence of coronary spasm or dissection. NR developed in 91 (10.9%) STEMI patients. Patients with NR had higher UAR and according to multivariable logistic regression models, a high UAR was an independent risk factor for NR. The area under the curve (AUC) value of the UAR was .760 (95%CI: .720-.801) in a receiver-operating characteristics curve (ROC) assessment. Notably, the UAR AUC value was greater than that of its components: albumin (AUC: .642) and serum uric acid (AUC: .637) (P < .05 for both comparisons). The optimum UAR value in detecting NR in STEMI patients was >1.21 with a sensitivity of 82% and a specificity of 67%. This was the first study to report that the UAR was independently associated with NR in STEMI patients who underwent pPCI.
The Association of Serum Uric Acid/Albumin Ratio With the Development of Coronary Collateral Circulation in Patients With Chronic Total Occluded Coronary Arteries
(Tabriz Univ Medical Sciences & Health Services, 2023) Saylik, Faysal; Cinar, Tufan; Sarikaya, Remzi; Akbulut, Tayyar; Selcuk, Murat; Ozbek, Emrah; Tanboga, Ibrahim Halil
Introduction: Coronary collateral circulation (CCC) develops in chronic total occluded (CTO) vessels and protects the myocardium against ischemia in addition to the improvement of cardiac functions. Poor CCC is related to adverse cardiac events as well as poor prognosis. Serum uric acid/albumin ratio (UAR) has emerged as a novel marker associated with poor cardiovascular outcomes. We aimed to investigate whether there was an association between UAR and poor CCC in CTO patients. Methods: This study was comprised of 212 patients with CTO (92 with poor CCC and 120 with good CCC). All patients were graded based on Rentrop scores to poor CCC (Rentrop scores 0 and 1) and good CCC (Rentrop scores 2 and 3). Results: Poor CCC patients had higher frequencies of diabetes mellitus, triglyceride levels, Syntax and Gensini scores, uric acid, and UAR and lower lymphocyte, high-density lipoprotein cholesterol, and ejection fraction when compared to good CCC patients. UAR was an independent predictor of poor CCC in CTO patients. Furthermore, UAR had a better discriminative ability for patients with poor CCC from good CCC compared to serum uric acid and albumin. Conclusion: Based on the results of the study, the UAR could be used to detect poor CCC in CTO patients.
Association of Tp-e/Qt Ratio With Syntax Score Ii in Patients With Coronary Artery Disease
(Taylor & Francis Ltd, 2022) Saylik, Faysal; Cinar, Tufan; Selcuk, Murat; Akbulut, Tayyar
Background. The SYNTAX score II (SS) is an angiographic tool, which grades the complexity of coronary artery lesions and predicts short- and long-term events. Tp-e/QT ratio is a novel electrocardiographic marker for the risk of ventricular arrhythmias. We aimed to investigate whether there was a correlation between SS and Tp-e/QT ratio.Methods. A total of 227 consecutive patients who underwent elective coronary angiography were enrolled in this study. Patients who had a lumen diameter >1.5 mm and at least % 50 diameter stenosis on coronary angiogram were determined as coronary artery disease (CAD) group, and others were identified as a control group. The SS was calculated for the CAD group, and SS >= 23 was defined as a high SS group, and SS < 23 was identified as a low SS group. Electrocardiographic indices, such as Tp-e and Tp-e/QT, were measured for all patients. A multivariable logistic regression analysis was performed with variables age, interventricular septum thickness (IVS), hypertension, and Tp-e/QT. Results. Tp-e interval and Tp-e/QT ratio were higher in the CAD group compared with the control group. Tp-e, corrected Tp-e (cTP-e) and Tp-e/QT were higher in the high SS group than in the low SS group. The cTp-e and Tp-e/QT were correlated with SS score. Age, IVS and Tp-e/QT ratio were independent predictors of high SS in the logistic regression analysis. Conclusions. Tp-e/QT ratio was an independent predictor of high SS and might be used for risk stratification in CAD patients.

Comparison of Long-Term Outcomes Between Intravascular Ultrasound-, Optical Coherence Tomography- and Angiography-Guided Stent Implantation: a Meta-Analysis
(Sage Publications inc, 2024) Saylik, Faysal; Hayiroglu, Mert Ilker; Akbulut, Tayyar; Cinar, Tufan
Intravascular ultrasonography (IVUS) and optical coherence tomography (OCT) guided percutaneous coronary interventions (PCI) are alternative techniques to angiography-guided (ANG-g) PCI in patients with coronary artery disease (CAD), especially for optimal stent deployment in coronary arteries. We conducted a network meta-analysis including studies comparing those three techniques. We searched databases for studies that compared IVUS, OCT, and ANG-g PCI in patients with CAD. Overall, 52 studies with 231,137 patients were included in this meta-analysis. ANG-g PCI had higher major adverse cardiovascular events (MACEs), all-cause death, cardiac death, myocardial infarction (MI), target lesion revascularization (TLR), and stent thrombosis (ST) than IVUS-guided PCI. Of note, both OCT-guided and IVUS-guided PCI had similar outcomes. The frequency of MACEs, cardiac death, and MI were higher in ANG-g PCI than in OCT-guided PCI. The highest benefit was established with OCT for MACEs (P-score=.973), MI (P-score=.823), and cardiac death (P-score=.921) and with IVUS for all-cause death (P-score=.792), TLR (P -score=.865), and ST (P-score=.930). This network meta-analysis indicated that using OCT or IVUS for optimal stent implantation provides better outcomes in comparison with ANG-g in patients with CAD undergoing PCI.
Comparison of Outcomes Between Single Long Stent and Overlapping Stents: a Meta-Analysis of the Literature
(Urban & Vogel, 2023) Saylik, Faysal; Cinar, Tufan; Selcuk, Murat; Cicek, Vedat; Hayiroglu, Mert Ilker; Orhan, Ahmet Lutfullah
ObjectivesThere is no consensus on whether to treat diffuse coronary artery lesions with a single long stent (SLS) or by overlapping two or more stents (OLS). The goal of this review was to compare the outcomes of these two approaches through a meta-analysis of the literature.MethodsWe searched for relevant studies in MEDLINE, Scopus, EMBASE, Google Scholar, and the Cochrane Library. Our meta-analysis included 12 studies (n = 6414) that reported outcomes during the follow-up period.ResultsIndividuals who received OLS had a greater risk of cardiac mortality and target lesion revascularization (TLR) than those who received SLS (RR: 1.51, CI: 1.03-2.21, p = 0.03, I-2 = 0% and RR: 1.64, CI: 1.02-2.65, p = 0.04, I-2 = 38%, respectively). The fluoroscopy period in the OLS group was longer than in the SLS group (SMD: 0.35, CI: 0.25-0.46, p < 0.01, I-2 = 0%). more contrast volume was sued for the OLS group; however, there was substantial variability in the pooled analysis (I-2 = 95%). In terms of all outcomes, there were no differences between stent generation types.ConclusionIn the first meta-analysis of mainly observational data comparing OLS vs. SLS for long coronary lesions, OLS had higher rates of cardiac mortality and TLR as well as longer fluoroscopy times compared to SLS.
Development and Validation of Nomogram Based on the Systemic-Immune Inflammation Response Index for Predicting Contrast-Induced Nephropathy in St-Elevation Myocardial Infarction Patients
(Sage Publications inc, 2024) Saylik, Faysal; Cinar, Tufan; Sarikaya, Remzi; Tanboga, Ibrahim Halil
Contrast-induced nephropathy (CIN) is a prominent complication of ST-elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (pPCI). The systemic immune inflammation response index (SIIRI) is a novel inflammatory marker developed by multiplying the monocyte count by the systemic immune inflammation index (SII) and is associated with coronary artery disease severity. We investigated the predictive ability of SIIRI for detecting CIN in STEMI patients (n = 2289) following pPCI and developed a nomogram based on SIIRI for risk stratifying. CIN was diagnosed based on an elevation in baseline creatinine levels >.5 mg/dL or 25% within 72 h after pPCI; 219 CIN (+) and 2070 CIN (-) patients were included. CIN (+) patients had higher SIIRI than CIN (-) patients and SIIRI was an independent predictor of CIN. A nomogram based on SIIRI had good calibration and discrimination abilities for predicting CIN development. SIIRI was superior to SII in discriminating CIN (+) patients. Adding SIIRI to the baseline model, which consists of age, hypertension, hemoglobin, estimated glomerular filtration rate, albumin, ejection fraction, lesion length, and pain-to-balloon time, had a higher discriminative ability and benefit in detecting CIN (+) patients than baseline model as assessed by decision curve analysis.
Digital Health Interventions in Patient Management Following Acute Coronary Syndrome: a Meta-Analysis of the Literature
(Kare Publ, 2023) Saylik, Faysal; Cinar, Tufan; Hayiroglu, Mert Ilker; Tekkesin, Ahmet Ilker
Objective: Acute coronary syndrome patients should be closely followed-up to maintain optimal adherence to medical treatments and to reduce adverse events. Digital health interventions might provide improved outcomes for patient care by providing closer follow-up, compared to standard care. Thus, in this meta-analysis, we aimed to evaluate the effect of digital health interventions on follow-up in acute coronary syndrome patients. Methods: We searched medical databases to obtain all relevant studies comparing digital health interventions with standard care in acute coronary syndrome patients. After reviewing all eligible studies, a meta-analysis was conducted with the remaining 11 randomized controlled studies and 2 non-randomized controlled studies. A modified Jadad scale and Newcastle-Ottawa scale were used to assess the quality of the publications for randomized controlled studies and non-randomized controlled studies, respectively. Results: This meta-analysis consisted of 7657 patients. The all-cause mortality rate was 49% lower in the digital health intervention cases, compared to those who received standard care [relative risk (RR) = 0.51 (0.37; 0.70), P <.01]. There was a significant decrease in systolic blood pressure in the digital health interventions group, compared to the standard care group [mean difference = -5.28 (-9.47; -1.08), P =.01]. The rate of nonadherence to anti-aggregant drugs was 69% lower in the digital health interventions than in the standard care group [RR = 0.31 (0.20; 0.46), P <.01]. Also, nonadherence rates for statin and beta-blockers were lower in the digital health interventions group. The risk of rehospitalization was observed to be 55% less in the digital health interventions patients, compared to the standard care group [RR = 0.45 (0.30; 0.67), P <.01]. Conclusion: Digital health interventions can be effective in follow-up for secondary prevention in acute coronary syndrome patients.

(Federal Reserve Bank St Louis, 2024) Saylik, Faysal; Cinar, Tufan; Akbulut, Tayyar; Hayiroglu, Mert Ilker; Selcuk, Murat; Uzuner, Zeynep Sevde Serdaroglu; Tanboga, Ibrahim Halil
Objective: Pregnancy causes physiological, hormonal, and hemodynamic changes that affect the aortic wall dimensions and elastic properties. Multiple pregnancies increase the risk of aortic enlargement and reduce aortic elasticity. The aortic stiffness index (ASI) and aortic velocity propagation (AVP) are markers of elasticity. Additionally, epicardial fat thickness (EFT) is associated with cardiovascular risk factors. The impact of multiparity on ASI, AVP, and EFT has not been previously reported in the literature. Therefore, we aimed to investigate the association of these parameters with the number of live pregnancies in this study. Methods: A total of 410 patients were enrolled in this prospective study. Patients were divided into three groups based on the number of live births: Group 1 (n = 0, 128 patients), Group 2 (4 >= n > 0, 157 patients), and Group 3 (n >= 5, 125 patients). A linear regression analysis was conducted to investigate trend associations of ASI, AVP, and EFT between the study groups. Multiple linear regression analysis was used to evaluate the independent predictors of continuous parameters. Results: There were increasing trends in multiparity with variables such as aortic systolic (ASD) and diastolic diameters, pulmonary artery diameters, ASI, and EFT, and a decreasing trend in AVP. The number of pregnancies was strongly and positively correlated with ASI, moderately and positively correlated with EFT and ASD, and moderately and negatively correlated with AVP. Conclusion: Multiparity was independently associated with ASI, EFT, ASD, and AVP, reflecting decreased elasticity and elevated cardiovascular risk in multiparous women.
Evaluating the Systemic Immune-Inflammation Index for In-Hospital and Long-Term Mortality in Elderly Non-St Myocardial Infarction Patients
(Springer, 2022) Orhan, Ahmet Lutfullah; Saylik, Faysal; Cicek, Vedat; Akbulut, Tayyar; Selcuk, Murat; Cinar, Tufan
Introduction This investigation aimed to evaluate the predictive value of the systemic immune-inflammation index (SII) for in-hospital and long-term mortality in elderly patients with non-ST-elevation myocardial infarction (NSTEMI). Methods This retrospective investigation included 314 consecutive elderly NSTEMI patients in a tertiary center. SII is computed as (neutrophils x platelets)/lymphocytes. Based on the increased SII values, we classified the research sample into three tertile groups as T1, T2, and T3. The in-hospital and long-term mortality were defined as the primary outcomes. Results Patients in the T3 group had lower chances of survival in the in-hospital and long-term periods compared with those in the T2 and T1 groups. According to the multivariable Cox regression models, SII independently related with in-hospital (hazard ratio (HR): 1.001, 95% CI: 1.000-1.1003, p = 0.038) and long-term mortality (HR: 1.004, 95% CI: 1.002-1.006, p < 0.001). To predict long-term mortality, the optimal SII value was > 2174 with 80% sensitivity and 85.4% specificity. SII had a slightly lower but statistically non-inferior discriminative ability for long-term mortality compared with the Charlson comorbidity index (CCI) in the receiver operating characteristic curve comparison (AUC: 86.2 vs. AUC: 890, p > 0.05). Additionally, combining SII with traditional risk factors and the CCI revealed a significant improvement in C-statistics. Conclusion This investigation may be the first to demonstrate that SII is independently linked with in-hospital and long-term mortality in elderly NSTEMI patients.

(Sage Publications inc, 2023) Cinar, Tufan; Saylik, Faysal; Akbulut, Tayyar; Korkmaz, Yetkin; Cicek, Vedat; Asal, Suha; Hayiroglu, Mert Ilker
The aim of this study was to examine the Intermountain Risk Score (IMRS) for short- and long-term mortality in ST elevation myocardial infarction (STEMI) patients and compare it with the well-known risk scores, such as the Thrombolysis in Myocardial Infarction (TIMI) and the Global Registry of Acute Coronary Events (GRACE). In this retrospective and cross-sectional study, 1057 consecutive patients with STEMI were evaluated. The end-points of the study were short- and long-term mortality. The overall mortality rate was 16% (n = 170 patients). The IMRS was significantly higher in STEMI patients who did not survive compared with those who survived. According to multivariable COX proportional regression analysis, the IMRS was independently related to both short- (HR: 1.482, 95% CI: 1.325-1.675, p < .001) and long-term mortality (HR: 1.915, 95% CI: 1.711-2.180, p < .001). The comparison of receiver operating characteristic curves revealed that the IMRS had non-inferior predictive capability for short- and long-term mortality than the TIMI and GRACE risk scores. To the best of our knowledge, this is the first study to show that the IMRS can predict short- and long-term prognosis of patients with STEMI. Further, the IMRS' predictive value for overall mortality was non-inferior compared with TIMI and GRACE scores.

(inst Nacional Nutricion, 2024) Cicek, Vedat; Yavuz, Samet; Saylik, Faysal; Taslicukur, Solen; Oz, Ahmet; Babaoglu, Mert; Cinar, Tufan
Background: Pan-immuno-inflammation value (PIV) is a new and comprehensive index that reflects both the immune response and systemic inflammation in the body. Objective: The aim of this study was to investigate the prognostic relevance of PIV in predicting in-hospital mortality in acute pulmonary embolism (PE) patients and to compare it with the well-known risk scoring system, PE severity index (PESI), which is commonly used for a short-term mortality prediction in such patients. Methods: In total, 373 acute PE patients diagnosed with contrast-enhanced computed tomography were included in the study. Detailed cardiac evaluation of each patient was performed and PESI and PIV were calculated. Results: In total, 60 patients died during their hospital stay. The multivariable logistic regression analysis revealed that baseline heart rate, N-terminal pro-B-type natriuretic peptide, lactate dehydrogenase, PIV, and PESI were independent risk factors for in-hospital mortality in acute PE patients. When comparing with PESI, PIV was non-inferior in terms of predicting the survival status in patients with acute PE. Conclusion: In our study, we found that the PIV was statistically significant in predicting in-hospital mortality in acute PE patients and was non-inferior to the PESI. (REV INVEST CLIN.

(Taylor & Francis Ltd, 2024) Saylik, Faysal; Cinar, Tufan; Selcuk, Murat; Tanboga, Ibrahim Halil
Aim: Inflammatory prognostic index (IPI), has been shown to be related with poor outcomes in cancer patients. We aimed to investigate the predictive role of IPI for contrast-induced nephropathy (CIN) development in non-ST segment elevation myocardial infarction patients using a nomogram and performing machine learning (ML) algorithms.Materials & methods: A total of 178 patients with CIN (+) and 1511 with CIN (-) were included.Results: CIN (+) patients had higher IPI levels, and IPI was independently associated with CIN. A risk prediction nomogram including IPI had a higher predictive ability and good calibration. Naive Bayes and k-nearest neighbors were the best ML algorithms for the prediction of CIN patients.Conclusion: IPI might be used as an easily obtainable marker for CIN prediction using ML algorithms.
Meta-Analysis of the Current Research on the Relationship Between Blood Lipid Levels and the Occurrence of Atrial Fibrillation
(Elsevier Science inc, 2023) Hayiroglu, Mert Ilker; Saylik, Faysal; Cinar, Tufan; Tokgozoglu, Lale
Background There is still debate in the literature about the relationship between lipid profile and the occurrence of atrial fibrillation (AF). In order to assess the association between blood lipid profiles and incidence of AF, this review was conducted to perform a meta-analysis of all available studies.Methods This review analysed all studies up to 28 February 2023 in PubMed, Google Scholar, and the Cochrane Library that included data regarding blood lipid levels and incidence of AF. For the purpose of calculating pooled estimates, the hazard ratios were extracted from all studies.Results Fourteen studies including 19 cohorts with 3,990,484 patients were included in this meta-analysis. An elevation of one standard deviation in total cholesterol (TC) level was associated with an 8% reduction (HR=0.92, 0.88-0.96; p<0.01) in the risk of developing AF. Although increased low-density lipoprotein cholesterol levels were associated with a 7% reduction in the development of AF (HR=0.93, 0.87-1.00; p=0.04), there was high heterogeneity in the random effects model (I-2=92%). Changes in high-density lipoprotein cholesterol and triglyceride levels were not found to be associated with AF risk in the pooled analysis. Dose-response meta-analysis showed that TC was inversely linearly associated with the risk of AF (p<0.001).Conclusions Higher TC levels were shown to be independently attributed to an increased risk of AF in individuals without cardiovascular disease. There was no association between the incidence of AF and triglyceride, high-density lipoprotein cholesterol, or low-density lipoprotein cholesterol blood levels.

(Mosby-elsevier, 2022) Cinar, Tufan; Saylik, Faysal; Akbulut, Tayyar; Asal, Suha; Selcuk, Murat; Cicek, Vedat; Orhan, Ahmet Lutfullah
Background: There is a limited data about the one-year outcomes of patients diagnosed with acute coronary syndrome (ACS) and coronavirus disease 2019 (COVID-19). Objectives: To assess one-year mortality of invasively managed patients with ACS and COVID-19 compared to ACS patients without COVID-19. Methods: In our investigation, we defined the study time period as April 30 through September 1, 2020. The control groups consisted of ACS patients without COVID-19 at the same time period and ACS patients prior to the pandemic, within the same months as those of the study. COVID-19 infection was confirmed in all participants utilizing real-time polymerase chain reaction testing. Results: This investigation examined 721 ACS participants in total. Among the participants, 119 patients were diagnosed with ACS and COVID-19, while 149 were diagnosed with ACS and without COVID-19. The other 453 ACS participants were diagnosed before the outbreak of the pandemic, within the same months as those of the study. One-year mortality rates were higher in the ACS participants with COVID-19 than in the ACS participants without COVID-19 and the pre-COVID-19 ACS participants (21.3% vs. 6.5% vs. 6.9%, respectively). An ACS along with COVID-19 was the only independent predictor of one-year mortality (HR=2.902, 95%Cl=1 .211-6.824, P = 0.018). According to the Kaplan-Meier survival curves, patients with ACS and COVID-19 had a lower chance of survival in the short-term and one-year periods. Conclusion: This is believed to be the first study to report that ACS patients with COVID-19 had higher one-year risk of mortality compared to ACS patients without COVID-19. (C) 2022 Elsevier Inc.

The Predictive Value of the Inflammatory Prognostic Index for Detecting No-Reflow in St-Elevation Myocardial Infarction Patients
(Arquivos Brasileiros Cardiologia, 2024) Saylik, Faysal; Cinar, Tufan; Tanboga, Ibrahim Halil
Background: No-reflow (NR) is characterized by an acute reduction in coronary flow that is not accompanied by coronary spasm, thrombosis, or dissection. Inflammatory prognostic index (IPI) is a novel marker that was reported to have a prognostic role in cancer patients and is calculated by neutrophil/lymphocyte ratio (NLR) multiplied by C -reactive protein/albumin ratio. Objective: We aimed to investigate the relationship between IPI and NR in ST -segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (pPCI). Methods: A total of 1541 patients were enrolled in this study (178 with NR and 1363 with reflow). Lasso panelized shrinkage was used for variable selection. A nomogram was created based on IPI for detecting the risk of NR development. Internal validation with Bootstrap resampling was used for model reproducibility. A two-sided p-value <0.05 was accepted as a significance level for statistical analyses. Results: IPI was higher in patients with NR than in patients with reflow. IPI was non-linearly associated with NR. IPI had a higher discriminative ability than the systemic immune-inflammation index, NLR, and CRP/albumin ratio. Adding IPI to the baseline multivariable logistic regression model improved the discrimination and net-clinical benefit effect of the model for detecting NR patients, and IPI was the most prominent variable in the full model. A nomogram was created based on IPI to predict the risk of NR. Bootstrap internal validation of nomogram showed a good calibration and discrimination ability. Conclusion: This is the first study that shows the association of IPI with NR in STEMI patients who undergo pPCI.
The Predictive Value of the Meld-Xi Score for Short- and Long-Term Mortality in Elderly Patients With Non-St Elevation Myocardial Infarction
(Springer, 2022) Cinar, Tufan; Saylik, Faysal; Selcuk, Murat; Akbulut, Tayyar; Orhan, Ahmet Lutfullah
Background In this study, we investigated the utility of the Model for End-stage Liver Disease excluding INR (MELD-XI) score in predicting short- and long-term mortality in elderly patients with non-ST elevation myocardial infarction (NSTEMI) who underwent coronary angiography (CAG). Methods In total, we analyzed 228 elderly NSTEMI patients above the age of 75. We used the modified 5-item frailty index and the Charlson Comorbidity Index (CCI) to assess the comorbidities. The MELD-XI score was calculated using the logarithmic relationship between the serum creatinine and total bilirubin. Results The median long-term follow-up was 530 [interquartile range (IQR) = 303-817] days and the short- and long-term mortality rates were 11.8% (n = 27) and 16.4% (n = 33), respectively. Patients who did not survive had a substantially higher MELD-XI score than those who did [10.1 (IQR = 7.8-15.1) vs. 4.5 (IQR = 1.9-6.9), p < 0.001, respectively]. Multivariable Cox regression analyses indicated that the MELD-XI score predicted both short- and long-term mortality independently. When the MELD-XI score, serum creatinine, and total bilirubin area under the curve (AUC) values were compared to predict long-term mortality, the MELD-XI score had the highest value (AUC: 0.833), followed by the serum creatinine (AUC: 0.741), and the total bilirubin (AUC: 0.723). The accuracy of the MELD-XI score was further tested with the GRACE risk score, which demonstrated noninferiority. Conclusion This was the first investigation which indicated that elderly NSTEMI patients with a high MELD-XI score had poor prognosis in the short- and long-term period.
The Predictive Value of Triglyceride-Glucose Index for In-Hospital and One-Year Mortality in Elderly Non-Diabetic Patients With St-Segment Elevation Myocardial Infarction
(Science Press, 2022) Saylik, Faysal; Cinar, Tufan; Selcuk, Murat; Tanboga, Ibrahim Halil
BACKGROUND Triglyceride-glucose (TyG) index, a reliable marker of insulin resistance, was associated with cardiovascular morbidity and mortality. This study aimed to evaluate the predictive value of TyG index for mortality in elderly non-diabetic patients with ST-segment elevation myocardial infarction (STEMI). METHODS In total, 430 non-diabetic patients aged over 65 years with STEMI were consecutively included. The TyG index was calculated by using the following formula: TyG index = ln (fasting triglyceride x fasting glucose/2). The 5-item modified frailty index score was utilized to determine comorbidities. Patients were divided into three groups based on TyG index tertiles. RESULTS Patients included into high TyG index tertile were male and had higher body mass index, glucose, triglyceride, low-density lipoprotein cholesterol, 5-item modified frailty index and GRACE risk score; and had low systolic blood pressure, estimated glomerular filtration rate and left ventricular ejection fraction. A one-unit increase in TyG index was associated with 3.03 extra cases per 1000 person-day for in-hospital mortality and 0.29 extra cases per 1000 person-day for long-term mortality. There was a non-linear relationship between TyG index and the risk of mortality with an increased risk above 8.5 for TyG index. KaplanMeier survival curves revealed that patients in high TyG index tertile had higher in-hospital and long-term mortality rates than those in low TyG index tertile. CONCLUSIONS This was the first study to demonstrate that the TyG index could predict in-hospital and long-term mortality in elderly non-diabetic STEMI patients.
