ABSTRACT
Objectives: Although the association of Atherogenic index of plasma (AIP) with coronary artery disease (CAD) and atherosclerosis is known, the relationship between AIP and in-stent restenosis (ISR) remains unclear. We aimed to investigate the relationship between AIP and ISR in patients with stable angina pectoris (SAP) treated with drug-eluting stent (DES). Methods: Patients with a history of DES implantation following stable angina were evaluated between January 2015 and November 2019 in this observational and retrospective study. 608 eligible patients were dichotomized into ISR+ (n=241) and ISR- (n=367). ISR was defined as the presence of 50% or greater stenosis. AIP was defined as log [TG/HDL-C]. Results: AIP levels were significantly higher in patients who developed ISR compared with those who did not (0.33 [0.15-0.52] vs 0.06 [-0.08-0.21] respectively, p<0.001). The AUC value of AIP levels for predicting ISR was 0.746 (p<0.001). Multivariate logistic regression analysis revealed that AIP, diabetes mellitus, higher LDL-C levels and lower LVEF values were independently associated with ISR. Conclusion: Multivariate analysis revealed that AIP was strongly independently associated with ISR. Using this novel inexpensive and easily calculable index may provide early recognition of ISR in patients with SAP who were treated with DES.
ABSTRACT
OBJECTIVE: In this study, we aimed to identify the reasons for and perceived challenges associated with the use of digital health technologies (DHT) in cardiology. METHOD: We distributed an online survey to Turkish Society of Cardiology member cardiologists (n = 2789) between January 10 and March 3, 2022. RESULTS: A total of 308 subjects responded (27.6% females, 62.0% aged 30-44 years). Of these, 42.5% worked at university hospitals, and 44.8% at state hospitals. Smart devices were used by 44.2% (136/308) for personal health monitoring. Additionally, 40.3% (117/290) used social media to provide medical information to patients, while 64.6% (193/299) did so for communication with other physicians. The self-reported recommendation frequencies of wearables, cardiac implantable electronic device telemonitorization, mobile health applications, and teleconsultation/televisit technologies were lower than the proportion of respondents who found DHT beneficial for both patients and physicians. The most frequently mentioned barriers for physicians were increased work burden and responsibilities (78.8%, 193/245), lack of financial compensation (66.9%, 164/245), and lack of relevant training (66.5%, 163/245). For patients, low technological adaptability (81.6%, 200/245), low health literacy (80.4%, 197/245), and low affordability (79.6%, 195/245) were the most frequently mentioned barriers. Additionally, the cost of technologies (69.4%, 170/245), concerns regarding data privacy and security (57.6%, 141/245), and data storage challenges (48.2%, 118/245) were the most significant technical impediments. CONCLUSION: The findings suggest that although the majority of physicians believe DHT to be beneficial for both themselves and their patients, the frequency of recommendations to patients remains low. A large-scale joint effort is required to address these issues and facilitate the integration of DHT into clinical practice.

Objectives: The prognostic significance of SYNTAX Score II (SS-II) is well-known in patients with chronic coronary syndromes. However, its predictive ability for mortality in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (p-PCI) remains unclear. Therefore, we aimed to investigate the prognostic accuracy of SS-II in STEMI patients who underwent p-PCI. Methods: A total of 743 STEMI patients treated with p-PCI were retrospectively analyzed. Study population was divided into three groups according to SS-II and defined as SS-IILOW ≤22.5 (n=245), 22.5
ABSTRACT
OBJECTIVES: We aimed to assess the incidence and predictors of prolonged hemodynamic depression (PHD) after carotid artery stenting (CAS). METHODS: We retrospectively analyzed data from 216 CAS procedures performed in 207 patients (156 male; median and interquartile range (IQR) of age 68 (62-73) yr) between July 2012 and October 2020. PHD was defined as hypotension (systolic blood pressure ≤ 90 mmHg) and/or bradycardia (heart rate < 60 bpm) lasting >1 h. RESULTS: The incidence of PHD was 25.9%. At multivariate analysis, asymptomatic lesions (OR: 2.43, 95% CI (1.16-5.06), p: 0.018), the stenosis proximity (<10 mm) to bifurcation (OR: 2.94, 95% CI (1.34-6.43), p: 0.007) and implantation of a Protege stent (OR: 2.93, 95% CI (1.14-7.53), p: 0.025) were independent risk factors, while statin usage (OR: 0.48, 95% CI (0.24-0.95), p: 0.036) was an independent protective factor for PHD after CAS. CONCLUSIONS: Patients with asymptomatic lesions and stenosis close to the bifurcation are more prone to PHD. The type of the stent selected significantly influences the risk of PHD. Further prospective randomized studies are warranted to investigate the possible protective role of statins against PHD after CAS.

BACKGROUND: Coronary artery ectasia (CAE) is described as the enlargement of a coronary artery segment by 1.5 times or more, which is generally associated with the atherosclerotic process. Atherosclerotic changes lead to arterial remodeling result in CAE. In our study, we measured serum transforming growth factor (TGF)-ß1 levels, which have a protective role against atherosclerosis. Further, we aimed to assess the TGF-ß1 gene variants rs1800469 (-509C>T, c.-1347C>T) and rs1800470 (c.+29T>C, p.Pro10Leu, rs1982073), which might have an effect on TGF production. Overall, 2877 patients were screened including 56 patients with CAE and 44 patients with normal coronary arteries who were included in the study. Serum TGF-ß1 levels were measured using ELISA and compared between two groups. Additionally, TGF-ß1 rs1800469 and rs1800470 gene variations were determined using TaqMan® SNP Genotyping Assays. RESULTS: Serum TGF-ß1 levels were significantly lower in patients with CAE than in controls (p=0.012). However, there was no difference in terms of the genotype and allele distributions of TGF-ß1 rs1800469 and rs1800470 polymorphisms. Serum TGF-ß1 levels were higher in individuals carrying the TGF-ß1 rs1800470 G allele (GG+AG) than in individuals with normal homozygous AA genotype in the CAE group (p=0.012). CONCLUSION: Our findings suggest that lower serum TGF-ß1 levels are associated with an increased risk for CAE development and that TGF-ß1 polymorphisms exert a protective effect. Furthermore, TGF-ß1 rs1800470 G allele carriers were shown to have higher TGF-ß1 levels in the CAE group. This suggests that having the G allele in the TGF-ß1 rs1800470 polymorphism could prevent CAE development.
ABSTRACT
BACKGROUND: Patients with acute coronary syndrome (ACS) have about a three-fold risk for developing contrast-induced acute kidney injury(CI-AKI). Investigating studies on routine hydration therapy have frequently included patients with stable coronary artery disease and high risk of CI-AKI [estimated glomerular filtration rate (eGFR) < 60 ml/min]. However, data on routine hydration treatment in non-ST segment elevation myocardial infarction (NSTEMI) patients with eGFR ≥60 ml/min are insufficient. We aimed to investigate the association between routine hydration therapy and CI-AKI development in NSTEMI patients at low risk for nephropathy. METHODS AND RESULTS: We randomly assigned a total of 401 NSTEMI patients to two groups: the routine hydration group (198 patients) and the nonhydration group (control group) (203 patients). Intravenous hydration with isotonic saline (1 ml/kg/h, 0.9% sodium chloride) was given for 3-12 h before and 24 h after contrast exposure to the hydration group. CI-AKI was defined as the increase in serum creatinine values 0.5 mg/dl or 25% between 48 and 72 h after the invasive procedures. In our study, the incidence of CI-AKI development in the routine hydration group (7.1%) was significantly lower than in the nonhydration group (14.1%) (P: 0.02). This study revealed that older age, amount of contrast media, and routine hydration were independent risk factors for developing CI-AKI (P < 0.01, P: 0.04, P < 0.01, respectively). CONCLUSION: We found that preprocedural and postprocedural intravenous hydration therapy reduces the development of CI-AKI in patients with NSTEMI at low risk for CI-AKI. We suggest administering routine hydration therapy in all ACS patients regardless of eGFR values.

OBJECTIVE: Endothelin-1 (ET-1) promotes the progression and induction of sclerotic renal changes in end-stage kidney disease. Membrane-bound endothelin-converting enzyme 1 (ECE-1) is involved in the production of ET-1. The aim of this study was to assess the effects of ECE-1b rs213045 and rs2038089 polymorphisms, which have been shown to be involved in the development of atherosclerosis, hypertension, and nephropathy, on the development of contrast-induced acute kidney injury (CI-AKI) in patients with acute coronary syndrome. METHODS: Our study included 38 patients with CI-AKI (CI-AKI[+]) and 55 patients without CI-AKI (CI-AKI[-]) who had coronary syndrome. The ECE-1b polymorphisms rs213045 and rs2038089 were assessed using real-time PCR. Serum ET-1 levels were measured by ELISA. RESULTS: The distributions of ECE-1b rs213045 and rs2038089 polymorphisms were similar between the two groups. Additionally, the serum ET-1 level did not different between the groups and was not associated with the ECE-1b polymorphisms. Peri-procedural low systolic blood pressure (SBP) was identified as a risk factor for CI-AKI development. CONCLUSION: Our findings indicate that ECE-1b rs213045 and rs2038089 polymorphisms are not associated with CI-AKI development and that peri-procedural low SBP is a risk factor for CI-AKI. However, variations in ECE-1b rs2038089 may contribute to the development of CI-AKI.

BACKGROUND: Cardiovascular disease is one of the leading causes of death worldwide. According to the results of various studies, protein convertase subtilisin kexin type-9 (PCSK9) was determined as a novel risk factor for stable coronary artery disease. Few studies have investigated the relationship between PCSK9 levels and the severity of coronary artery disease in patients with acute coronary syndrome; thus, we herein aimed to investigate this relationship in patients with non-ST-elevation myocardial infarction (NSTEMI) who underwent coronary angiography. PATIENTS AND METHODS: Herein, 168 patients with NSTEMI were prospectively enrolled, and severity of atherosclerotic lesions was determined using SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery (SYNTAX), Gensini and Jeopardy scores. Plasma PCSK9 levels, lipid parameters and C-reactive protein levels were measured after a 12-h fasting period. The relationship of PCSK9 levels and clinical and laboratory parameters of patients with their SYNTAX, Gensini and Jeopardy scores was investigated. RESULTS: Pearson correlation analysis showed a strong positive correlation between PCSK9 and the three scores (P < 0.001, r > 0.5 for all). In ROC analysis, a mid-high SYNTAX score of at least 25 was predicted with a sensitivity of 81% and a specificity of 63% when the PCSK9 level was higher than 52.8 ng/ml (area under a curve 0.76, P < 0.001). Multivariate linear regression analysis revealed that PCSK9, low-density lipoprotein cholesterol and creatinine levels were independent predictors of a high SYNTAX score. CONCLUSION: Taken together, high PCSK9 levels may be a risk factor for adverse events in patients with NSTEMI. Aggressive lipid-lowering therapies may benefit this group of patients.

OBJECTIVE: This study is designed to evaluate the recently developed AnTicoagulation and Risk factors In Atrial fibrillation (ATRIA) risk score (RS), which determines the predisposition to thromboembolic and hemorrhagic events in atrial fibrillation, as a predictor of prognosis in patients having acute myocardial infarction (AMI), and to compare the predictive ability of ATRIA RS with GRACE RS. METHODS: We analyzed 1627 patients having AMI who underwent coronary angiography and/or percutaneous coronary intervention (PCI) between January 2011 and February 2015. The primary endpoints included all-cause mortality, non-fatal MI, and cerebrovascular events during follow-up. RESULTS: Multivariate Cox regression analysis showed that the ATRIA RS>3 was an independent predictor of major adverse cardiac events in patients with AMI [hazard ratio, 2.00, 95% confidence interval, 1.54 to 2.60, p<0,001]. The area under the curve (AUC) for ATRIA RS and GRACE RS was 0.66 and 0.67 (p<0.001, and p<0.001), respectively. We performed a pair-wise comparison of receiver operating characteristic curves,and noted the predictive value of ATRIA RS with regard to primary endpoints was similar to that of GRACE RS (By DeLong method, AUCATRIA vs. AUCGRACE z test=0.64, p=0.52). CONCLUSION: ATRIA RS may be useful in predicting prognosis in patients having AMI during long-term follow-up.

Contrast-induced acute kidney injury (CI-AKI) is associated with increased mortality, morbidity, and prolonged hospitalization. Patients with acute coronary syndrome (ACS) have a 3-fold higher risk of developing CI-AKI. The aim of our study was to evaluate the predictors of CI-AKI and long-term prognosis in patients with ACS who developed CI-AKI (1083 patients were enrolled). Contrast-induced acute kidney injury was defined as an increase of ≥0.5 mg/dL and/or an increase of ≥25% of pre-percutaneous coronary intervention (PCI) to post-PCI serum creatinine levels within 48 to 72 hours after the procedure. Primary end point was defined as all-cause mortality, myocardial infarction, and cerebrovascular event at long-term follow-up (36 ± 12 months). Contrast-induced acute kidney injury occurred in 178 (16.4%) of the 1083 patients. The primary end points were significantly high in patients with ACS who developed CI-AKI ( P < .001). The occurrence of CI-AKI was identified as an independent predictor of primary end point. Risk of CI-AKI development was more frequently seen in patients with ACS. Also, patients who developed CI-AKI have worse prognosis at long-term follow-up. Additional preventive treatment strategies need to be developed in this group of patients.

We assessed the relation between platelet-to-lymphocyte ratio (PLR) on admission and contrast-induced nephropathy (CIN) in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). A total of 488 patients with NSTE-ACS who underwent urgent coronary angiography were enrolled. Levels of PLR and creatinine were measured before angiography and at 72 hours after angiography. Patients were divided into 2 groups, namely, the CIN group, 80 patients (16.3%; age 65.3 ± 12.5years; 66.7% men) and the non-CIN group, 408 patients (83.7%; age 61.2 ± 12.3 years; 72.5% men). Patients in the CIN group had significantly higher PLR than those in the non-CIN group (152.9 ± 99.6 vs 120.4 ± 66.1, P < .001). In logistic regression analysis, PLR (odds ratio [OR] 1.004, 95% confidence interval [CI] 1.001-1.007, P = .02), diabetes mellitus (OR 1.75, 95% CI 1.02-2.98, P = .03), and ST-segment depression on admission electrocardiogram (OR 1.68, 95% CI 1.00-2.81, P = .04) were independent predictors of CIN. The PLR was an independent predictor of CIN after angiography in patients with NSTE-ACS.
