The MAPH Score Predicts Coronary Slow Flow. A Retrospective Case-Controlled Study.

AIM: The MAPH score is a new score that combines mean platelet volume (MPV), hematocrit, and total protein, which are markers of whole blood viscosity (WBV). We aimed to investigate the relationship between the MAPH score and the coronary slow flow phenomenon (CSF). MATERIAL AND METHODS: A total of 201 patients were included in the study. 105 had CSF and 96 had normal coronary flow (NCF). Coronary flow was measured by the Thrombolysis in Myocardial Infarction frame count (TFC) method. The patients' MPV, age, hematocrit, and total protein were recorded. High (HSR) and low shear rates (LSR) were calculated, based on total protein and hematocrit values. Cut-off values for CSF were determined using the Youden's index, and the score was determined as 0 or 1 according to the cut-off values. The sum of these scores was the MAPH score. RESULTS: The mean age of the patients included in the study was 51.1±7.9 (n=201, 54.2 % male). Hyperlipidemia, DM, and HT rates of both groups were similar, but the mean age of the CSF group was higher (p=0.773; p=0.549; p=0.848; p <0.001, respectively). Total protein, MPV, hematocrit, HSR and LSR were higher in the CSF group (p< 0.001, for all values). Comparative receiver operating characteristic (ROC) curve analysis showed that the performance of the MAPH score in predicting CSF is better than the performance of these parameters separately. CONCLUSION: A new score, the MAPH score, may be used to identify the presence of CSF.

Relationship between blood viscosity and thrombus burden in ST-segment elevation myocardial infarction.

BACKGROUND: Increased whole blood viscosity (WBV) is associated with increased infarct area, impaired microvascular circulation and mortality in patients with ST-elevation myocardial infarction (STEMI). OBJECTIVES: We aimed to analyze the association between the WBV and thrombus burden (TB) in STEMI patients. METHODS: This cross-sectional study included 167 STEMI patients who received primary percutaneous coronary intervention. WBV values were assessed using hematocrit and total protein values, and low shear rate(LSR) and high shear rate(HSR) were calculated. Angiographic TB was assessed according to the definition of the Thrombolysis in Myocardial Infarction (TIMI) study group. The cases were dichotomized into low TB (grade 1-3) (n = 87) and high TB (grade 4-5) (n = 80) groups. RESULTS: The mean HSR and LSR values of the high TB group were significantly increased compared to the low TB group (p < 0.001, for each). In ROC analysis,for prediction of TB, a cut-off value of 3.83 WBV for HSR had a 71% sensitivity and a 60.7% specificity, and a cut-off value of 21 WBV for LSR had a 70% sensitivity and 59.9% specificity (p < 0.001,for each). Multivariate regression analysis showed that both HSR (OR = 2.408;p=0.020) and LSR (OR = 1.055;p=0.021) were independent predictors for high TB. CONCLUSION: Increased WBV was an independent predictor for the presence of high TB in patients with STEMI.

Systemic Immune Inflammation Index is a Novel Marker in Predicting the Presence and Severity of Isolated Coronary Artery Ectasia. / O Índice de Inflamação Imune Sistêmica é um Novo Marcador na Previsão da Presença e Gravidade aa Ectasia Coronariana Isolada.

BACKGROUND: The underlying pathology of isolated coronary artery ectasia (CE) has not been fully elucidated. OBJECTIVE: We aimed to examine the relationship between the systemic immune inflammation index (Sii), which corresponds to the multiplying of the neutrophil-to-lymphocyte ratio (NLR) and the platelet counts, and isolated CE. METHOD: The retrospective study population included 200 patients with isolated CE, 200 consecutive with obstructive coronary artery disease, and 200 consecutive with a normal coronary artery angiogram. A 2-sided p-value of <0.05 was considered significant. RESULTS: Sii, NLR, platelet-to-lymphocyte ratio (PLR), and monocyte-to-high density lipoprotein cholesterol ratio (MHR) were significantly higher in the CE group compared with the other groups (all p<0.001). In multivariate analysis, Sii (p<0.001, OR = 1.005, 95% CI =1.004-1.005) was found to be an independent predictor of isolated CE. In Receiver Operating Characteristic curve analysis, Sii had a higher Area Under the Curve than NLR, PLR, and MHR. Sii value of >517.35 has 79% sensitivity, 76% specificity for the prediction of the CE [AUC: 0.832, (p<0.001)]. Sii had a significant correlation with the number of ectatic coronary arteries and Markis classification (r:0.214 p=0.002; r:-0.195, p=0.006, respectively). CONCLUSION: To the best of our knowledge, this is the first study that Sii was significantly associated with isolated CE presence and anatomical severity.

FUNDAMENTO: A patologia subjacente da ectasia da artéria coronária (EC) isolada não foi totalmente elucidada. OBJETIVO: Nosso objetivo foi examinar a relação entre o índice de inflamação imune sistêmica (Sii), que corresponde à multiplicação da razão neutrófilos-linfócitos (RNL) e as contagens de plaquetas, e EC isolada. MÉTODO: A população do estudo retrospectivo incluiu 200 pacientes com EC isolada, 200 consecutivos com doença arterial coronariana obstrutiva e 200 consecutivos com angiografia coronária normal. Um valor de p bicaudal <0,05 foi considerado significativo. RESULTADOS: Sii, RNL, razão plaqueta-linfócito (RPL) e razão monócito-colesterol de lipoproteína de alta densidade (MHR) foram significativamente maiores no grupo EC em comparação com os outros grupos (todos p<0,001). Na análise multivariada, Sii (p<0,001, OR = 1,005, IC 95% =1,004-1,005) foi considerado um preditor independente de EC isolada. Na análise da curva Receiver Operating Characteristic (ROC), Sii teve uma área sob a curva maior em comparação com RNL, RPL e MHR. O valor de Sii >517,35 tem 79% de sensibilidade, 76% de especificidade para a predição do EC [AUC: 0,832, (p<0,001)]. Sii teve correlação significativa com o número de artérias coronárias ectásicas e classificação de Markis (r: 0,214 p=0,002; r:-0,195, p=0,006, respectivamente). CONCLUSÃO: Até onde sabemos, este é o primeiro estudo em que Sii foi significativamente associado à presença isolada de EC e gravidade anatômica.

The Role of Systemic Immune Inflammation Index for Predicting Saphenous Vein Graft Disease in Patients with Coronary Artery Bypass Grafting.

As inflammation plays a significant role in the development of coronary artery disease, we hypothesized that there may be a relation between the systemic immune inflammation index (SII) and saphenous vein graft disease (SVGD). The study population consisted of 716 consecutive patients who underwent elective coronary angiography (CAG) >1 year after bypass grafting. The patients were divided into 2 groups depending on the extent of SVG patency. SII value was significantly higher in the SVGD(+) group compared with the SVGD(-) group (P < .001). In multivariate logistic regression analysis, SII (P < .001, odds ratio (OR) = 3.27, 95% CI = 1.94-5.65) and neutrophil-to-lymphocyte ratio (NLR) (P < .001, OR = 2.08, 95% CI = 1.59-3.11) were found to be independent predictors of SVGD. An SII value of >935 (x103/ml) has 89.2% sensitivity and 70.6% specificity for the prediction of the SVGD, and an NLR value of >4.15 has 54.6% sensitivity and 68.5% specificity for the prediction of the SVGD. The AUC of SII was found to be greater than the AUC of NLR (P = .002), platelet-to-lymphocyte ratio (PLR) (P = .009), lymphocyte-to-monocyte ratio (LMR) (P = .013), MPV (P = .011), and C-reactive protein (CRP) (P = .034) in predicting SVGD. In conclusion, we demonstrated that SII, which is among the new inflammation indexes, is a more reliable predictor in determining SVGD than the NLR, PLR, and LMR.

Association between Circulating Omentin-1 Levels and Aortic Valve Sclerosis.

Background: Aortic valve sclerosis (AVS) is characterized by thickening of the valve leaflets accompanied by increased echogenicity and calcification without significant limitations in valve movements. Omentin-1 is a glycoprotein of the adiponectin family released from visceral adipose tissue, and it can be used as a biomarker of atherosclerosis, obesity, and metabolic syndrome. No studies have demonstrated any relationship between AVS and omentin-1 in the literature. We aimed to explore the association of serum omentin-1 levels with AVS. Methods: Eighty-six patients with AVS and 92 age- and sex-matched controls were enrolled into the study. The baseline clinical characteristics of the patients were recorded. Conventional 2-dimensional echocardiography was performed. Omentin-1 levels were measured. Results: The mean omentin-1 level was significantly lower in the AVS (+) group compared to the control group (78.16 ± 44.95 vs. 163.57 ± 59.84 ng/mL, p < 0.001). Omentin-1 [odds ratio (OR) = 3.45, 95% confidence interval (CI) = 1.88-5.39, p < 0.001,] and LDL-C (OR = 1.82, 95% CI = 1.33-2.16, p = 0.015) were found to be independent predictors of AVS in multivariate logistic regression analysis. An omentin-1 level of < 92.45 ng/mL had 90.5% sensitivity and 71.4% specificity for the prediction of AVS (area under curve: 0.697, p < 0.001). Conclusions: Our results indicated that a lower omentin-1 level was associated with an increased risk of AVS. We suggest that omentin-1 could be used as a treatment target as well as to predict AVS.

Association of serum elabela levels with carotid artery stenosis in patients with non-cardioembolic ischemic stroke.

Aim: Elabela (ELA) is a peptide of the apelinergic system and is known to play a role in endothelial homeostasis and vascular pathobiology. In this study, the relationship between carotid artery stenosis, which is the main culprit, and ELA level in patients with non-cardioembolic ischemic stroke was investigated. Materials & methods: Cross-sectional observation included two groups of 40 patients with critical carotid artery stenosis and 40 patients with age-sex matched noncritical carotid artery stenosis. Results: ELA levels were significantly higher in the noncritical stenosis group. ELA had a significantly moderate negative correlation with the carotid score (r = -0.334, p = 0.003), maximal carotid plaque length (r = -0.413, p < 0.001) and degree of stenosis (r = -0.397, p < 0.001). Conclusions: There is a significant inverse correlation between critical carotid artery disease and ELA level in patients with non-cardioembolic ischemic stroke.

Reduced CTRP3 Levels in Patients with Stable Coronary Artery Disease and Related with the Presence of Paroxysmal Atrial Fibrillation. / Níveis Reduzidos de CTRP3 em Pacientes com Doença Arterial Coronariana Estável Relacionados à Presença de Fibrilação Atrial Paroxística.

BACKGROUND: Serum Complement C1q/tumor necrosis factor-related protein-3 (CTRP3) levels and the relationship with atrial fibrillation (AF) in stable coronary artery disease (CAD) are not clearly known. OBJECTIVE: The aim of this study was to investigate the change in serum CTRP3 levels and its relationship with paroxysmal AF in stable CAD. METHOD: The study included 252 patients with CAD and 50 age-sex matched healthy control subjects. Serum CTRP3 levels were measured in addition to routine anamnesis, physical examination, laboratory and echocardiography examinations. The patients were divided into groups with and without CAD and CAD patients with and without paroxysmal AF. Statistical significance was accepted as p<0.05. RESULTS: Serum CTRP3 levels were found to be significantly lower in patients with CAD than in the control group (p<0.001). AF was detected in 38 patients (15.08%) in the CAD group. The frequency of hypertension and female gender, hs-CRP, blood urea nitrogen, creatinine levels and left atrial end-diastolic (LAd) diameter were higher (p<0.05 for each one), and CTRP3 levels were lower in patients with AF (p <0.001). In the logistic regression analysis, serum CTRP3 levels and LAd diameters were independently determined the patients with AF (p<0.01 for each one). In this analysis, we found that every 1 ng/mL reduction in CTRP3 levels increased the risk of AF by 10.7%. In the ROC analysis of CTRP3 values for detecting patients with AF, the area under the ROC curve for CTRP3 was 0.971 (0.951-991) and was statistically significant (p<0.001). When the CTRP3 cut-off value was taken as 300 ng/mL, it was found to predict the presence of AF with 87.9% sensitivity and 86.8% specificity. CONCLUSION: Serum CTRP3 levels were significantly reduced in patients with stable CAD and decreased CTRP3 levels were closely related to the presence of paroxysmal AF in these patients.

FUNDAMENTO: Os níveis de Proteína 3 relacionada ao fator de necrose tumoral/complemento sérico C1q (CTRP3) e a relação com a fibrilação atrial (FA) na doença arterial coronária estável (DAC) não estão claros atualmente. OBJETIVOS: O objetivo deste estudo foi investigar a mudança nos níveis séricos de CTRP3 e sua relação com a FA paroxística em DAC estável. MÉTODO: O estudo incluiu 252 pacientes com DAC e 50 controles saudáveis com idade/sexo compatíveis. Os níveis séricos de CTRP3 foram medidos, além da anamnese de rotina, exame físico, exames laboratoriais e ecocardiograma. Os pacientes foram divididos em grupos com e sem DAC e indivíduos com DAC com e sem FA paroxística. Os valores eram estatisticamente significativos quando p<0,05. RESULTADOS: Os níveis séricos de CTRP3 foram significativamente menores em pacientes com DAC do que no grupo controle (p<0,001). A FA foi detectada em 28 pacientes (15,08%) no grupo DAC. A frequência de hipertensão e do sexo feminino, a proteína C reativa de alta sensibilidade (PCR-as), o nitrogênio ureico no sangue, os níveis de creatinina e o diâmetro diastólico do átrio esquerdo foram maiores (p<0,05 para cada um), e os níveis de CTRP3 foram mais baixos em pacientes com FA (p<0,001). Na análise de regressão logística, os níveis séricos de CTRP3 e os diâmetros diastólicos do átrio esquerdo foram independentemente determinados pelos pacientes com FA (p<0,01 para cada um). Nesta análise, observamos que cada 1 ng/mL de redução nos níveis de CTRP3 aumentou o risco de FA em 10,7%. Na análise ROC dos valores de CTRP3 para detectar pacientes com FA, a área da curva ROC para CTRP3 foi 0,971 (0,951­991) e considerada estatisticamente significativa (p<0,001). Quando o ponto de corte de CTRP3 foi considerado em 300 ng/mL, demonstrava a presença de FA com 87,9% de sensibilidade e 86,8% de especificidade. CONCLUSÃO: Os níveis séricos de CTRP3 caíram significativamente em pacientes com DAC estável, e níveis reduzidos de CTRP3 estiveram relacionados à presença de FA paroxística nesses pacientes.

Relationship between atherogenic index of plasma and stent thrombosis in patients with acute coronary syndrome.

OBJECTIVE: Stent thrombosis (ST) is an uncommon but serious complication in patients undergoing percutaneous coronary intervention (PCI). This study aimed to investigate the effect of atherogenic index of plasma (AIP) on ST. METHODS: Among the 10,258 patients who underwent coronary angiography between January 2018 and December 2020, 239 patients who underwent PCI with the diagnosis of acute coronary syndrome (ACS) due to ST were included as the study group (ST group) and 459 patients who underwent percutaneous intervention for ACS and did not have any in-stent lesion as the control group (non-ST group). ST classification was done according to the Academic Research Consortium definition. RESULTS: The mean age of the patients was 63.3±10.6 years (483 male, 69.2%). The groups were similar in terms of characteristic properties, comorbidities, and the drugs being used (p>0.05 for all). Drug eluting stents were used in 86.5% of the patients. In the ST group, the median time from stent implantation to thrombosis was 285 days. Mean AIP and the ratio of triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) were statistically significantly higher in the ST group than in the controls (p<0.001 and p=0.018, respectively), and a positive correlation was observed between time from stent implantation to thrombosis and AIP and TG/HDL-C (rS=0.229, p=0.010 and rS=0.222, p=0.010, respectively). Multivariate logistic regression analysis revealed that stent length, prior ST elevation myocardial infarction, TG/HDL-C, and AIP were independent predictors of ST. CONCLUSION: AIP is an easy calculable biomarker, and the performance of AIP to predict ST is better than TG/HDL-C.

A New Score for Determining Thrombus Burden in STEMI Patients: The MAPH Score.

AIM: to investigate whether the MAPH score, which is a new score that combines blood viscosity biomarkers such as mean platelet volume (MPV), total protein and hematocrit, can be used to predict thrombus burden in ST-segment elevation myocardial infarction (STEMI) patients. METHODS: A total of 473 consecutive patients with STEMI were included in the study. Intracoronary tirofiban/abciximab infusion was applied to patients with thrombus load ≥3 and these patients (n = 71) were defined as the patient group with high thrombus load. MPV, age, hematocrit and total protein values of the patients were recorded. High shear rate (HSR) and low shear rate (LSR) were calculated from total protein and hematocrit values. Cut-off values were determined for high thrombus load by using Youden index, and score was determined as 0 or 1 according to cut-offs. The sum of the scores was calculated as the MAPH score. RESULTS: The mean age of the patients included in the study was 59.6 ± 12.6 (n = 354 male, 74.8%). There was no difference between the groups in terms of gender, HT and DM (P = .127, P = .402 and P = .576, respectively). In the group with high thrombus load; total protein, MPV and hematocrit values were higher (P < .001, P = .001 and P = .03, respectively). Comparison of receiver operating characteristic (ROC) curve analysis revealed that the MAPH score had better performance in predicting higher thrombus load than both other self-containing parameters and HSR and LSR. CONCLUSION: The MAPH score may be a new score that can be used to determine thrombus burden in STEMI patients.

The ATRIA and Modified-ATRIA Scores in Evaluating the Risk of No-Reflow in Patients With STEMI Undergoing Primary Percutaneous Coronary Intervention.

The no-reflow (NR) phenomenon is frequently encountered in acute coronary syndrome. We evaluated the association between anticoagulation and risk factors in atrial fibrillation (ATRIA) and modified ATRIA risk scores and NR in ST-elevation myocardial infarction (STEMI). Consecutive patients (n = 551) who underwent primary percutaneous coronary intervention between December 2019 and June 2020 due to STEMI were included. The mean age of the patients was 60.5 ± 10.8 years (n = 369, 67% male). The ATRIA and modified anticoagulation and risk factors in atrial fibrillation-hyperlipidemia, smoking, male (m-ATRIA-HS) scores were calculated. The NR group had higher frequency of diabetes mellitus (DM), serum creatine kinase-MB (CK-MB) levels, and corrected thrombolysis in myocardial infarction frame count (cTFC) (P = .002, P = .006, and P < .001, respectively). In regression analysis, ATRIA, m-ATRIA-HS, thrombus grade, and cTFC were independent predictors of NR. Age, higher CK-MB, and neutrophil-to-lymphocyte ratio and DM were the other predictors for NR. Pairwise comparison of receiver operating characteristics curve analysis showed that the m-ATRIA-HS (>2, area under curve [AUC]: 0.715) has better performance than ATRIA score (>1, AUC: 0.656), with a P < .022 and z statistics 2.279. In conclusion, ATRIA, especially the m-ATRIA-HS, can be used to evaluate NR risk in STEMI.

Glasgow prognostic score as a marker of mortality after TAVI

Abstract Introduction: The Glasgow prognostic score (GPS) reflects host systemic inflammatory response and has been reported to be significant as a prognostic indicator in cancer-bearing patients. The aim of this study was to evaluate the predictive value of GPS in outcomes of patients with severe aortic stenosis who were treated with transcatheter aortic valve implantation (TAVI). Methods: The study population consisted of 79 patients who underwent TAVI due to severe aortic stenosis between January 2018 and March 2019 in our clinic. Echocardiographic and laboratory data were recorded before the procedure and GPS was scored as 0, 1, or 2, based on serum albumin and C-reactive protein levels. European System for Cardiac Operative Risk Evaluation II scoring system was used for risk stratification. The primary endpoints of the study were postoperative in-hospital mortality, hospitalization due to cardiac causes, or mortality within a year. Results: The 79 patients were classified into two groups according to outcomes. Fifteen patients (19%) reached the primary endpoints at one year of follow-up. Compared to the patients who did not reach the endpoints, these 15 patients were not different in terms of age, preoperative mean gradient, and ejection fraction (P>0.05 for all). GPS was the only laboratory parameter with statistically significant difference between the groups (P=0.008) and multivariate analysis showed that GPS was independent predictor of primary endpoints (P=0.012, odds ratio 4.51, 95% confidence interval 1.39-14.60). Conclusion: GPS is an easy, noninvasive laboratory test which may be used as a predictive biomarker for outcomes in patients undergoing TAVI.

Relationship between CANLPH score and in-hospital mortality in patients undergoing coronary artery bypass grafting.

Aim: To evaluate the CANLPH score in in-hospital mortality after coronary artery bypass grafting. Materials & methods: The 999 patients were included in this retrospective cohort study. Neutrophil/lymphocyte ratio, C-reactive protein/albumin ratio and platelet/hemoglobin ratio were determined and the CANLPH score was calculated as the sum score of 0 or 1 by the cutoff in each ratio. Results: Twenty-five patients who reached the primary end point were defined as the mortality group and the remaining as the nonmortality group. The CANLPH score was noninferior to the European System for Cardiac Operative Risk Evaluation II in receiver-operating characteristic curve analysis with difference between AUC: 0.0162, standard error (SE): 0.0394, z statistics: 0.682 and p = 0.494. Conclusion: The CANLPH score may be more appropriate in assessing the risk of in-hospital mortality after coronary artery bypass grafting.

Lay abstract Mortality, morbidity and complications of coronary artery disease depend largely on inflammatory processes. The CANLPH score, a combination of three different ratios, can better determine inflammation. We aimed to evaluate the CANLPH score in in-hospital mortality after coronary artery bypass grafting. The 999 patients were classified into two groups according to the primary end point. Twenty-five patients (2.5%) who reached the primary end point were defined as the mortality group and the remaining 974 patients as the nonmortality group. The multivariate logistic regression analysis showed that the European System for Cardiac Operative Risk Evaluation II, neutrophil/lymphocyte ratio, platelet/hemoglobin ratio and the CANLPH score were independent predictors of primary end point after coronary artery bypass grafting. The CANLPH score may be more appropriate than neutrophil/lymphocyte ratio, C-reactive protein/albumin ratio and platelet/hemoglobin ratio in assessing the risk of in-hospital mortality after coronary artery bypass grafting.

Predictive role of Frontal QRS-T angle and Selvester QRS Score in determining angiographic slow flow phenomenon following percutaneous coronary intervention in patients with Non-ST elevation myocardial infarction.

AIM: Slow flow (SF) that develops after percutaneous coronary intervention (PCI) is significantly associated with poor prognosis in Non-ST elevation myocardial infarction (Non-STEMI) patients. Increased Selvester QRS score and Frontal QRS-T angle [f(QRS-T)] are related to adverse cardiovascular outcomes. We aimed to investigate the predictive role of the Selvester QRS score and f(QRS-T) for the development of post-PCI SF in patients with Non-STEMI. METHOD AND RESULTS: In a retrospective study, 210 patients with Non-STEMI were divided into two groups as SF (29) and Non-SF (181) according to their TIMI coronary flow grade. For all patients the Selvester QRS score and f(QRS-T) were calculated from automatic electrocardiography (ECG) reports. The mean age of the study population was 63 (55-75) years and 102 (68.6%) of patients were male. The Selvester QRS score and f(QRS-T) were higher in the SF group than in the Non-SF group [(5[3-8], 3[2-5]); (67° [42°-88°], 39° [24°-59°]), respectively, all p <0.01]. In a logistic regression analysis, the Selvester QRS score (OR = 4,862; 95% (CI) = 1,131-20,904, p =0.03) and f(QRS-T) (OR = 5,489; 95% (CI)= 11,433-21,034, p =0.01) were found independent predictors of post-PCI SF in Non-STEMI patients. Receiver operating characteristic (ROC) analysis was performed to assess the diagnostic values of the Selvester QRS score [86% sensitivity; 44% specificity; cut off 2; (AUC, 0.693)] and f(QRS-T) [62% sensitivity; 73% specificity; cut off 58°; (AUC, 0.778)]. CONCLUSION: The Selvester QRS score and f(QRS-T), both easy-to-calculate ECG parameters, are predictors of post-PCI SF in Non-STEMI patients.

The ATRIA score is superior to the m-CHA2DS2-Vasc score in predicting in-hospital mortality in COVID-19.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) has become a health and social problem all over the world. Most of the deaths occur from embolism and thrombus formation. We aimed to compare the predictive value of the anticoagulation and risk factors in atrial fibrillation (ATRIA) and m-CHA2DS2-Vasc scores in in-hospital mortality in COVID-19. METHODS: Three-hundred and ninety-four patients who were hospitalized due to COVID-19 between 10 June 2020 and 10 September 2020 were included. Three-hundred and sixty patients who survived were defined as the non-mortality group and the remaining 34 whose hospitalizations resulted in death were defined as the mortality group. The anticoagulation and risk factors in atrial fibrillation and m-CHA2DS2-Vasc scores of the patients were calculated. RESULTS: A total of 394 patients, mean age 66.2±9.7 (221 male [56.1%]) were included in this retrospective study. The median values of the anticoagulation and risk factors in atrial fibrillation and m-CHA2DS2-Vasc scores were different between the groups (p<0.000 for both). The multivariate logistic regression analysis showed that both the m-CHA2DS2-Vasc and anticoagulation and risk factors in atrial fibrillation scores were independent predictors of in-hospital mortality (p=0.024, 95%CI 1.039-1.704 for anticoagulation and risk factors in atrial fibrillation and p=0.043, 95%CI 1.012-2.088 for m-CHA2DS2-Vasc). In the receiver operating characteristic curve analysis, the anticoagulation and risk factors in atrial fibrillation score was superior to the m-CHA2DS2-Vasc score with an AUC 0.774 and SE:0.037, and p<0.001. CONCLUSIONS: In our study, we showed that the anticoagulation and risk factors in atrial fibrillation and m-CHA2DS2-Vasc scores can be used as predictors of thrombosis and mortality in COVID-19 patients. In addition, the predictive value of the anticoagulation and risk factors in atrial fibrillation score was higher than that of m-CHA2DS2-Vasc. The use of the anticoagulation and risk factors in atrial fibrillation score to assess high-risk patients in COVID-19 may be recommended.

Combined effects of nutritional status on long-term mortality in patients with non-st segment elevation myocardial infarction undergoing percutaneous coronary intervention.

OBJECTIVE: The aim of this study was to investigate the performance of controlling nutritional status (CONUT) index, geriatric nutritional risk index (GNRI), and prognostic nutritional index (PNI) scores in predicting the long-term prognosis of patients with non-ST-elevated myocardial infarction (NSTEMI) who underwent percutaneous coronary intervention (PCI). METHODS: A total of 915 patients with NSTEMI (female: 48.4%; mean age: 73.1±9.0 years) who underwent PCI at Adana Numune Training and Research Hospital, Cardiology Clinic between January 2014 and January 2015 were included in this cross-sectional and retrospective study. CONUT, GNRI, and PNI scores were calculated based on the admission data derived from samples of peripheral venous blood. The mean follow-up duration was 64.5±15.4 months. RESULTS: During follow-up (mean 64.5±15.4 months), 179 patients (19.6%) died. The mean GNRI and PNI scores were significantly lower in the nonsurvivor group; however, the median CONUT score was significantly higher in the nonsurvivor group compared with the survivor group. The receiver operating characteristic (ROC) curve analyses have shown that GNRI score has similar performance to the CONUT score and has better performance than PNI score in predicting 5-year mortality. The Kaplan-Meier curve analysis has shown that patients with lower PNI or GNRI had higher cumulative mortality than the patients with higher PNI or GNRI. Also, the patients with higher CONUT scores had higher cumulative mortality compared with those with lower scores. The multivariate analyses have shown that GNRI (HR: 0.973), PNI (HR: 0.967), CONUT score (HR: 1.527), and body mass index (BMI) (HR: 0.818) were independent predictors of the 5-year mortality in patients with NSTEMI. CONCLUSION: In this study, we have shown that CONUT score, GNRI, and PNI values were associated with the long-term mortality in patients with NSTEMI who underwent PCI, and GNRI yielded similar results to CONUT score but was better than PNI.

Glasgow Prognostic Score as a Marker of Mortality after TAVI.

INTRODUCTION: The Glasgow prognostic score (GPS) reflects host systemic inflammatory response and has been reported to be significant as a prognostic indicator in cancer-bearing patients. The aim of this study was to evaluate the predictive value of GPS in outcomes of patients with severe aortic stenosis who were treated with transcatheter aortic valve implantation (TAVI). METHODS: The study population consisted of 79 patients who underwent TAVI due to severe aortic stenosis between January 2018 and March 2019 in our clinic. Echocardiographic and laboratory data were recorded before the procedure and GPS was scored as 0, 1, or 2, based on serum albumin and C-reactive protein levels. European System for Cardiac Operative Risk Evaluation II scoring system was used for risk stratification. The primary endpoints of the study were postoperative in-hospital mortality, hospitalization due to cardiac causes, or mortality within a year. RESULTS: The 79 patients were classified into two groups according to outcomes. Fifteen patients (19%) reached the primary endpoints at one year of follow-up. Compared to the patients who did not reach the endpoints, these 15 patients were not different in terms of age, preoperative mean gradient, and ejection fraction (P>0.05 for all). GPS was the only laboratory parameter with statistically significant difference between the groups (P=0.008) and multivariate analysis showed that GPS was independent predictor of primary endpoints (P=0.012, odds ratio 4.51, 95% confidence interval 1.39-14.60). CONCLUSION: GPS is an easy, noninvasive laboratory test which may be used as a predictive biomarker for outcomes in patients undergoing TAVI.

Assessment of the relationship among breast milk intake, birth pattern, antibiotic use in infancy, and premature atherosclerosis.

OBJECTIVE: Previous studies have shown cesarean section (C-section) and antibiotic use in the infantile period lead to chronic diseases in later life. It is also known that breastfeeding, which forms the basal system of immunity, is a protector in neonates. In this study, we aimed to investigate the association between breastfeeding, antibiotic use, C-section, and premature atherosclerosis. METHODS: A total of 100 patients who underwent coronary angiography and had stenosis in at least 1 epicardial vessel and 100 controls with normal coronaries were included in the study. In addition to traditional risk factors, type of delivery, breast milk intake and duration, and antibiotic use and frequency were evaluated for each participant. Lipid profile was added to the study procedure. Angiographic images of the study groups were examined to calculate the Gensini score. RESULTS: Smoking, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and family history were different between the groups. In the control group, 3 were born via C-section, whereas 26 were born via C-section in the atherosclerosis group (p<0.001). Breast milk intake and duration was also significantly higher in the control group (p=0.018). Antibiotic use was less in the control group, but there was no statistically significant difference (p=0.099). In multivariate logistic regression analysis, diabetes mellitus, smoking, and C-section were predictors of atherosclerosis (p=0.036, p=0.001, and p=0.003, respectively). In receiver operating characteristics curve analysis, the ability of C-section to predict premature atherosclerosis was superior to diabetes but not to smoking (area under curve, 0.607; p=0.023). CONCLUSION: Mode of delivery and breast milk intake should be evaluated and considered among the risk factors of premature atherosclerosis.

The Impact of Transcatheter Aortic Valve Implantation (TAVI) on Serum Apelin Levels in Patients with Aortic Valvular Stenosis

Abstract Introduction: In this study, we aimed to investigate the impact of transcatheter aortic valve implantation (TAVI) on serum apelin levels in patients with severe symptomatic aortic valve stenosis (AS). Methods: Forty-six consecutive patients (76.9±7.4 years, n=27 women) who underwent TAVI and 45 age- and sex-matched control subjects were included in the study. Echocardiographic parameters, serum apelin, pro-brain natriuretic peptide (Pro-BNP), and troponin I levels were compared between the groups. In addition, the preprocedural and first-month follow-up echocardiographic parameters and serum apelin values of TAVI patients were compared. Results: Serum median troponin I and Pro-BNP levels were significantly higher and serum apelin levels were significantly lower in TAVI patients before TAVI procedure than in the control subjects (P<0.001, for all). Median troponin I and Pro-BNP levels were significantly decreased and apelin levels were significantly increased after TAVI procedure compared to the peri-procedural levels. There was a significant and moderate negative correlation between Pro-BNP and apelin levels measured before and after TAVI procedure. A statistically significant and strong negative correlation was found between aortic valve area and Pro-BNP level before TAVI procedure, while a statistically significant but weak positive correlation was found between valve area and apelin level. Conclusion: In our study, apelin levels were significantly lower and Pro-BNP levels were higher in AS patients compared with the control group. Moreover, after TAVI procedure, a significant increase in apelin levels and a significant decrease in Pro-BNP levels were observed. There was also a negative and moderate correlation between apelin and Pro-BNP levels.
