Comparison of frontal QRS-T angle and inflammatory parameters between the patients with drug-naive first episode psychosis and healthy controls.

BACKGROUND: Frontal QRS-T (fQRS-T) angle is a novel marker to predict many cardiovascular diseases. The present study aims to compare the fQRS-T angle of first episode psychosis (FEP) patients and healthy controls (HC) and evaluate the relationship between fQRS-T angle and blood count-related inflammatory markers such as neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and monocyte to high-density lipoprotein cholesterol ratio (MHR). METHODS: Electrocardiogram (ECG) and complete blood count (CBC) of 63 patients who were diagnosed with drug-naive FEP in the psychiatry clinic of a training and research hospital and 78 healthy controls (HC) individuals who had applied to the health committee polyclinic for recruitment or pre-military examination between 2016 and 2021 were included. RESULTS: fQRS-T angle was wider in FEP patients (55.5o) than in healthy controls (22o) (p < .001). NLR, PLR, and MHR were higher in FEP patients than in healthy controls (p = .001, p < .001, and p < .001, respectively). fQRS-T angle was positively correlated with NLR (r = 0.52 and p < .001) and MHR (r = 0.39 and p = .002) in FEP patients. NLR (t = 2.196 and p = .032) and MHR (t = 5.469 and p < .001) values were found to be the predictors of fQRS-T angle in FEP patients. CONCLUSION: In summary, we can conclude that patients with FEP tend to exhibit a wider fQRS-T angle compared to their healthy controls. Additionally, the values of NLR and MHR could potentially serve as useful indicators for predicting the fQRS-T angle in FEP patients. Conducting subsequent long-term studies could provide deeper insights into the interpretation of the fQRS-T angle and its potential connection to cardiovascular diseases in schizophrenia patients.

The Clinical Importance of C-Reactive Protein to Albumin Ratio (CAR) in Patients with Pulmonary Thromboembolism.

BACKGROUND: Pulmonary thromboembolism (PTE) commonly arises from lower extremity thrombus and can be fatal if left untreated. To date, many laboratory biomarkers have been used for predicting the prognosis in patients with PTE. C-reactive protein (CRP) to albumin ratio (CAR) is a new biomarker of systemic inflammation. In this study, we aimed to evaluate the clinical importance of CAR in PTE patients. METHODS: One hundred thirty-three eligible patients who were followed up with the diagnosis of PTE in our hospital between July 2016 and May 2020 were retrospectively evaluated in this study. The patients were divided into three groups as non-massive, sub-massive, and massive PTE. RESULTS: The results of complete blood counts (CBC) and biochemical analysis were evaluated among three groups. Neutrophil, neutrophil to lymphocyte ratio (NLR), D-dimer, troponin, CRP, albumin, and CAR were significantly different among groups. According to multivariate logistic regression analysis, CAR and troponin were determined as the independent predictors of massive PTE. Also, CAR was determined as the only independent predictor of in-hospital mortality in patients with PTE. CONCLUSIONS: CAR may be a reliable and easily accessible parameter to determine the severity and prognosis in PTE patients.

C-Reactive Protein/Albumin Ratio as a Novel Predictor of Contrast Induced Nephropathy in Patients With Stable Angina Pectoris.

The relationship between C-reactive protein (CRP) to albumin ratio (CAR) and contrast-induced nephropathy (CIN) in patients with acute coronary syndrome has been reported. However, the relevance of CAR in patients with stable angina pectoris (SAP) has not been clarified. We hypothesized that CAR might predict the development of CIN in patients with SAP undergoing coronary angiography (CAG). Patients (n = 554) with SAP who underwent CAG were included in the study. CIN was defined as a ≥25% increase in serum creatinine compared with baseline value within 72 h of CAG. Participants were divided into two groups: CIN (n = 87) and non-CIN (n = 467). Age, CRP, CAR, mean corpuscular volume (MCV), urea, uric acid, contrast medium volume, the percent of percutaneous coronary intervention were significantly greater, whereas albumin and high-density lipoprotein were significantly lower in the CIN group than non-CIN group (p < .05, for all). Multivariate analysis showed that CAR was the only independent predictor for CIN (odds ratio = 7.065, 95% confidence interval (CI); 3.279-15.221, p < .001). Receiver operating characteristic ROC analysis showed that a CAR ≥ 0.1164 could predict CIN (sensitivity of 71% and specificity of 72%; area under curve = 0.736; 95% CI: 0.677-0.795, p < .001). CAR was significantly greater in patients who developed CIN and this independently predicted CIN.

The Safety and Tolerability of Nebivolol in Hypertensive Patients with Coronary Artery Disease and Left Ventricular Ejection Fraction ≥ 40%: A Population-Based Cohort Study (Nebivolol-TR Study).

BACKGROUND: This study aimed to assess the safety and tolerability of nebivolol in hypertensive patients with coronary artery disease and left ventricular ejection fraction ≥ 40% in a Turkish cohort. METHODS: A total of 1015 hypertensive patients and coronary artery disease with left ventricular ejection fraction ≥ 40% were analyzed from 29 different centers in Turkey. Primary outcomes were the mean change in blood pressure and heart rate. Secondary outcomes were to assess the rate of reaching targeted blood pressure (<130/80 mmHg) and heart rate (<60 bpm) and the changes in the clinical symptoms (angina and dyspnea). Adverse clinical events and clinical outcomes including cardiovascular mortality, cardiovascular hospital admissions, or acute cardiac event were recorded. RESULTS: The mean age of the study population was 60.3 ± 11.5 years (male: 54.2%). During a mean follow-up of 6 months, the mean change in blood pressure was -11.2 ± 23.5/-5.1 ± 13.5 mmHg, and the resting heart rate was -12.1 ± 3.5 bpm. Target blood pressure and heart rate were achieved in 76.5% and 37.7% of patients. Angina and functional classifications were improved by at least 1 or more categories in 31% and 23.2% of patients. No serious adverse events related to nebivolol were reported. The most common cardiovascular side effect was symptomatic hypotension (4.2%). The discontinuation rate was 1.7%. Cardiovascular hospital admission rate was 5% and hospitalization due to heart failure was 1.9% during 6 months' follow-up. Cardiovascular mortality rate was 0.1%. CONCLUSION: Nebivolol was well tolerated and safe for achieving blood pressure and heart rate control in hypertensive patients with coronary artery disease and heart failure with preserved or mildly reduced ejection fraction.

The relationship between myocardial bridge and frontal QRS-T angle.

Aim: Although Myocardial bridge (MB) is known as a benign condition, it has been demonstrated to be associated with cardiac arrhythmias and poor outcomes. Frontal QRS-T angle (fQRSTa) is a novel indicator of repolarization and depolarization heterogeneity. Last studies indicated that associated with fQRSTa and adverse cardiac events. No study evaluated the relationship between fQRSTa and MB. In the present study, we aimed to investigate the relationship between MB and fQRSTa. Methods: This study included 91 patients with normal coronary arteries and 89 patients with MB. Coronary angiography was performed in all patients due to ischemia findings on treadmill exercise test or myocardial scintigraphy.2-lead surface electrocardiograms (ECGs) of all patients were evaluated. QT interval, fQRSTa, QTc interval were measured from surface ECGs. Results: Baseline clinical, echocardiographic and laboratory parameters were similar between MB and control group. However, when compared to control group, patients with MB had importantly raised fQRSTa [27 (20-41) vs. 23 (12-37) p = 0.007]. In correlation analysis, fQRSTa was positively correlated with MB length (r = 0.411, p < 0.001). Linear regression analysis showed that MB length was the just considerable predictor of fQRSTa (ß = 0.247, p = 0.041). Conclusions: The fQRSTa is a novel electrocardiographic marker that can be easily obtained from surface ECG. We have shown for the first time that MB length is a significant predictor of fQRSTa.

The Effect of Low-Flow and Normal-Flow Desflurane Anesthesia on the Frontal QRS-T Angle in Patients Undergoing Rhinoplasty Operation: A Randomized Prospective Study.

INTRODUCTION: Low-flow anesthesia (LFA) has gained more interest worldwide owing to its economic and ecological advantages compared to normal-flow anesthesia (NFA). Desflurane is one of the commonly used anesthetic agents for LFA, but it may prolong myocardial repolarization. Frontal QRS-T angle (f[QRS-T]a) is a novel marker of myocardial repolarization. To our knowledge, no study has compared the effect of LFA and NFA on f(QRS-T)a. In this study, we aimed to compare the effect of the LFA and NFA with desflurane on f(QRS-T)a in patients undergoing rhinoplasty operation. METHODS: A total of 80 patients undergoing rhinoplasty operations were included in this prospective study. The patients were randomized into two groups as follows: LFA (n = 40) and NFA (n = 40). The frontal QRS-T angle was calculated from the automatic report of the electrocardiography device (Nihon Kohden, Tokyo, Japan). It was recorded at the following time points: T1: preoperative (basal), T2: immediately after anesthesia induction, T3: immediately after endotracheal intubation, T4: 5 min after endotracheal intubation, T5: 15 min after endotracheal intubation, T6: 30 min after endotracheal intubation, T7: 60 min after endotracheal intubation, T8: end of the operation, T9: 15 min after the end of the operation. RESULTS: Baseline clinical characteristics and laboratory parameters were similar between the two groups. In the LFA group, f(QRS-T)a was significantly increased at only the T3 time point when compared to T1 (P = 0.003). However, in the NFA group, f(QRS-T)a was significantly increased at T3, T4, T5, T6, T7, T8, and T9 time points when compared to the T1 value (P < 0.05, for all). On the other hand, fQRS-Ta was significantly higher in the NFA group than in the LFA group at T4, T5, and T6 time points.  Conclusion: In our study, we have shown for the first time that NFA significantly increased the f(QRS-T)a, whereas LFA did not significantly increase the f(QRS-T)a except for immediately after the endotracheal intubation. It was also detected that f(QRS-T)a was significantly higher in the NFA group compared to that in the LFA group. Therefore, it can be concluded that LFA has more protective effects on myocardial repolarization than NFA.

The relationship between oxidative stress and autophagy and apoptosis in patients with paroxysmal atrial fibrillation.

Although the pathophysiology of paroxysmal atrial fibrillation (PAF) is not fully known, oxidative stress (OS) and atrial remodeling seem to be important triggers. Autophagy and apoptosis which are the types of cell death are fundamental processes in the human body. Although they investigated in many diseases, no study evaluated these parameters in PAF patients. We aimed to investigate autophagy and apoptosis which may be associated with atrial remodeling, and to show whether these factors are associated with OS in PAF patients. In this study, 44 PAF patients admitted to our clinic and 44 healthy volunteers were included. Serum total oxidative stress (TOS), total antioxidant status (TAS), oxidative stress index (OSI), and ATG5 for autophagy and serum M30 for apoptosis were studied. Serum TOS, OSI, ATG5, M30 and left atrium (LA) diameter were higher, while TAS was lower in PAF group than the control group (p < 0.001, for all). ATG5 was positively correlated with TOS, OSI and LA, whereas negatively correlated with TAS. Also, M30 was positively correlated with TOS and OSI, whereas negatively correlated with TAS. Logistic regression analysis showed that TOS (P = 0.002), ATG5 (p = 0.013) and M30 (p = 0.006) were independent predictors of the PAF. It also found that ATG5 was the only independent predictor of LA enlargement in linear regression analysis. Our study showed that ATG5 and M30 were increased, and they were correlated with OS in patients with PAF. Therefore, we suggest that autophagy and apoptosis may play an important role in the PAF process.

Comparison of frontal QRS-T angle in patients with schizophrenia and healthy volunteers.

Cardiovascular diseases are the most prominent cause of death in patients with schizophrenia. Frontal QRS-T (fQRS-T) angle is a novel marker of myocardial depolarization and repolarization heterogeneity. Recent studies have indicated that the fQRS-T angle is associated with some cardiovascular abnormalities. This study aimed to investigate the fQRS-T angle and its relationship with symptoms severity in patients with schizophrenia. One hundred-six patients with schizophrenia and sixty-four healthy controls were included in this study. fQRS-T angle and QT interval measurements were calculated for each participant from the automatic report of the 12-lead electrocardiography (ECG) device. The Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) and The Positive and Negative Syndrome Scale (PANSS) were performed on the patients with schizophrenia. Corrected QT (QTc) interval and fQRS-T angle were significantly higher in the patients with schizophrenia than healthy controls (p < 0.001 and p < 0.001, respectively). fQRS-T angle was positively correlated with age (r = 0.43), duration of disease (r = 0.37), and negative symptoms scores (r = 0.39). In linear regression analysis, the disease duration and negative symptom severity were the independent predictors of fQRS-T angle in patients with schizophrenia (t = 3.730, p = 0.003 and t = 2.257, p = 0.023, respectively). The fQRS-T angle may be an important ECG parameter to interpret cardiovascular disease risk in patients with schizophrenia.

Evaluation of structural valve deterioration and bioprosthetic valve failure utilizing the new European consensus definition in patients undergoing TAVI with first-generation devices: Outcomes beyond 5 years from a single center in Turkey.

OBJECTIVE: The long-term durability of transcatheter aortic bioprosthetic valves continues to be a major concern. Standardized criteria of the structural valve deterioration (SVD) and bioprosthetic valve failure (BVF) have recently been defined. Limited studies have evaluated the long-term durability of transcatheter aortic valve implantation (TAVI) according to these new definitions. We aim to analyze the durability of TAVI beyond 5 years and to report the frequency of SVD and BVF. METHODS: A total of 89 patients who had undergone TAVI and had theoretically completed at least 5 years after the procedure were included. Either a Medtronic CoreValve or an Edwards SAPIEN XT valve were implanted in the patients. New standardized definitions were used to evaluate SVD and BVF. RESULTS: The mean age of the patients was 78.70±6.95 years. SVD occured in 4 (4.5%) patients during 6 years of follow-up. Severe SVD was observed in 2 patients (2.2%), and these patients had the New York Heart Association class II symptoms. Both patients with severe SVD also met the criteria of BVF. Moderate SVD was observed in 2 patients (2.2%), and these patients had no valve-related symptoms. Of the 4 SVD cases, 2 were associated with increased mean transaortic gradients, whereas the remaining 2 cases were associated with intraprosthetic aortic regurgitation. All patients with SVD are still alive, and none of them have required aortic valve reintervention. CONCLUSION: Although first-generation TAVI devices were used, we determined the low rate of SVD and BVF at the 6-year follow-up. It may be suggested that there is no major concern associated with TAVI even with first-generation devices regarding long-term durability.

The relationship between frontal QRS-T angle and the severity of newly diagnosed chronic obstructive pulmonary disease.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is characterised by persistent airflow restriction and respiratory symptoms. Studies demonstrated that cardiac arrhythmias and cardiovascular mortality increased in these patients as a result of altered myocardial repolarization. Frontal QRS-T angle is a novel marker of myocardial depolarization and repolarization heterogeneity. In this study, we aimed to investigate the relationship between frontal QRS-T angle and disease severity in patients with newly diagnosed COPD. METHODS: A total of 104 newly diagnosed COPD patients were included in this study. Patients were divided into two groups according to GOLD (Global Obstructive Lung Disease) stage as follows: patients with mild and moderate COPD (group I), and severe and very severe COPD (group II). Frontal QRS-T angle was calculated from the automatic report of the electrocardiography device. RESULTS: Frontal QRS-T angle was significantly higher in group II patients compared with in group I patients (43.0 [25.5-60.0] vs. 20.0 [12.0-32.0], P < .001). The best cut-off value of frontal QRS-T angle for predicting severe-very severe COPD was ≥34.5°. Correlation analysis showed that frontal QRS-T angle was negatively correlated with FEV1/FVC (r = -.524, P < .001) and MEF25-75 (r = -.453, P < .001). Multivariate logistic regression analysis was showed that frontal QRS-T angle was the only independent predictor of severe-very severe COPD (OR: 1.051, 95% CI: 1.024-1.079, P < .001). CONCLUSIONS: Frontal QRS-T angle is an easily obtainable marker form surface electrocardiography. In this study, we have shown for the first time that frontal QRS-T angle was significantly increased in patients with severe and very severe COPD.

Effect of noise on the electrocardiographic parameters.

PURPOSE: Noise, defined as any sound that is unpleasant, is one of the most important environmental problems. Prolonged exposure to noise has been shown to be associated with the development of cardiovascular diseases. No study investigated the effect of noise on surface electrocardiography (ECG). AIMS: The aim of our study is to investigate the effect of noise on surface ECG parameters including P-wave dispersion (PWD), QT intervals, corrected QT interval (QTc), T-wave peak to end (Tp-e) interval, and Tp-e/QT and Tp-e/QTc ratios. METHODS: A total of 51 people working in the textile factory affected by the noise and 43 volunteers without any disease and who were not exposed to noise were included in this study. The average noise level in the textile factory was 112 dB. A 12-lead ECG was obtained from all individuals. PR interval, PWD, QRS duration, QT interval, QTc interval, Tp-e interval, and Tp-e/QT and Tp-e/QTc ratios were calculated for all individuals. RESULTS: The noise group had significantly increased PWD [35 (28-40) vs. 28 (22-36) p = 0.029], QT interval ( 373.5 ± 27.3 vs. 359.3 ± 2.74, p = 0.001), QTc interval [(409 ± 21 vs. 403 ± 13 p = 0.045)], Tp-e interval [(90.6 ± 6.0 vs. 83.5 ± 7.3 p < 0.001)], Tp-e/QT [(0.24 ± 0.03 vs. 0.23 ± 0.02, p = 0.015)] and Tp-e/QTc [(0.22 ± 0.02 vs. 0.21 ± 0.02 p < 0.001)] compared to control group. Also, duration of working was positively correlated with PWD (r = 0.468, p = 0.001) and Tp-e/QTc ratio (r = 0.328, p = 0.019). In multiple linear regression linear regression analysis, noise was the independent predictor of both PWD (ß = 0.244, p = 0.032) and Tp-e/QTc (ß = 0.319, p = 0.003) CONCLUSION: We showed that noise significantly increased PWD, QT and Tp-e interval measurements. Also, noise was the independent predictor for both PWD and Tp-e/QTc.

Relationships between paroxysmal atrial fibrillation, total oxidant status, and DNA damage.

INTRODUCTION: Structural and electrophysiological changes play a critical role in the development of atrial fibrillation (AF). Although the pathophysiology of paroxysmal AF (PAF) has not been fully elucidated, oxidative stress (OS) and DNA damage appear to be important triggers. Thus far, no studies have investigated the relationships among total oxidant status (TOS), DNA damage, and PAF. The goal of this study was to assess TOS and DNA damage in patients with PAF. METHODS: This cross-sectional study included 56 patients with PAF and 31 healthy controls. OS was assessed based on TOS, total antioxidant capacity (TAC), and oxidative stress index (OSI). The level of DNA damage was assessed using 8-hydroxy-2'-deoxyguanosine (8-OHdG). RESULTS: There were no significant differences between the groups in terms of baseline characteristics. However, patients with PAF had significantly higher high-sensitivity C-reactive protein (p=0.018), TOS (p=0.001), OSI (p=0.001), and 8-OHdG (p=0.019) levels, compared with the control group. Multivariate logistic regression analysis showed that serum TOS level (odds ratio: 1.608; 95% confidence interval [CI]: 1.188-2.176, p=0.002) was the only independent predictor of PAF. TOS ≥12.2 predicted PAF with a sensitivity of 82% and specificity of 76% (AUC: 0.785, 95% CI: 0.687-0.883, p<0.001). CONCLUSION: We found that TOS and DNA damage were significantly greater in patients with PAF than in the control group. Therefore, we propose that TOS and DNA damage can be used to detect patients at higher risk of AF.

The high dose unfractionated heparin is related to less radial artery occlusion rates after diagnostic cardiac catheterisation: a single centre experience.

BACKGROUND: Transradial approach (TRA) has increasingly become the default strategy for cardiac catheterisation. However, TRA can result in several complications; radial artery occlusion (RAO) is the most unwilling complication. Unfractionated heparin (UFH) is an effective therapy in preventing RAO. The goal of this study was to evaluate whether weight-adjusted high dose UFH reduces the rate of RAO after diagnostic cardiac catheterisation compared to weight-adjusted standard dose UFH. METHODS: A total of 1215 patients screened and after exclusion criteria, 686 consecutive patients were enrolled. 100 IU/kg UFH (high dose UFH group) and 50 IU/kg UFH (standard dose UFH group) were given the patients undergoing diagnostic cardiac catheterisation. RAO was evaluated with vascular Doppler ultrasonography at 10 days after cardiac catheterisation. RESULTS: Among 686 patients undergoing diagnostic cardiac catheterisation, RAO was detected in 36 (5.2%) patients. There was no significant difference with respect to baseline characteristics and co-morbid diseases between high dose UFH group and standard dose UFH group. RAO was significantly higher in standard dose UFH group than high dose UFH group (7.9% vs. 3.0%, p = .004). Multivariate logistic regression analysis was demonstrated that age (OR: 0.958, 95% CI: 0.924-0.993, p = .019) and standard dose heparin (OR: 2.811, 95% CI: 1.347-5.866, p = .006) were independent factor for RAO. CONCLUSIONS: High dose UFH was independently associated with a lower rate of RAO. Given that RAO nearly affects about 10% patient underwent TRA, prefer to high dose UFH may be a reasonable choice for RAO prevention.

Effect of anemia on the frontal QRS-T angle.

BACKGROUND: Anemia is a common health problem worldwide and is associated with a poor prognosis for cardiovascular diseases. It can alter myocardial depolarization and repolarization by affecting the generation and propagation of electrical impulses. The frontal QRS-T angle is a novel marker of the absolute difference between myocardial depolarization and repolarization. This study investigated the effects of anemia on the frontal QRS-T angle. METHODS: The study included 66 anemic subjects with no cardiac disorders, and 50 age- and gender-matched controls. Twelve-lead electrocardiography (ECG) was obtained for all subjects, and the frontal QRS-T angle was calculated based on the automatic report of the ECG machine. RESULTS: Subjects with anemia had a significantly higher frontal QRS-T angle than subjects without anemia (28.9±14.1 vs. 22.5±11.8, P=0.011). In correlation analysis, the frontal QRS-T angle was positively correlated with the Body Mass Index (BMI; r=0.287, P=0.002), left ventricular mass (LVM; r=0.264, P=0.004), and heart rate (r=0.275, P=0.003) and negatively correlated with the hemoglobin level (r=-0.349, P<0.001). Multivariate regression analysis showed that the hemoglobin level (ß=-0.254, tß=-2.805, P=0.006), BMI (ß=0.240, t=2.770, P=0.007), and LVM (ß=0.201, t=2.303, P=0.023) were independently associated with the frontal QRS-T angle. CONCLUSIONS: The hemoglobin level was found to be an independent predictor of the frontal QRS-T angle.

Comparisons of microbiota-generated metabolites in patients with young and elderly acute coronary syndrome.

OBJECTIVE: Acute coronary syndrome (ACS) is a leading cause of death worldwide. There is great interest in defining the risk factors and underlying mechanisms of ACS among young people. The microbiota and its metabolites have recently become a popular research topic, yet there is still no study that investigated microbiota-generated metabolites as a possible risk factor in young patients with ACS. In this study, we aimed to investigate the relationship between microbiota-generated metabolites and ACS in young people. METHODS: This study included 44 young patients with ACS (<50 years of age), 39 elderly patients with ACS, and 44 patients with normal coronary arteries. Inflammatory parameters and serum trimethylamine N-oxide (TMAO) and choline levels were measured in all patients. RESULTS: Young patients with ACS had significantly higher levels of TMAO and choline compared to the control and elderly ACS groups. Also, elderly patients with ACS had a significantly higher level of TMAO than the control group. Linear regression analysis was performed to determine the independent predictors of TMAO. Two regression models were involved. The first model included young ACS and control groups, while the second model included young and elderly ACS groups. In the first model, we found that young ACS (ß=0.399, p=0.004) and smoking ACS (ß=0.211, p=0.046) were significantly associated with TMAO level. In the second model, young ACS was significantly associated with TMAO level (ß=0.230, p=0.035). CONCLUSION: In this study, we have shown that young ACS was significantly associated with increased TMAO level.

New risk factors in determining long­term mortality in patients undergoing TAVI: can the conventional risk scores be used as a long­term mortality predictor?

BACKGROUND: Surgical risk in patients after transcatheter aortic valve implantation (TAVI) is determined by conventional scoring systems. However, these risk scores were developed to predict surgical mortality. Due to their insufficient predictive ability in patients after TAVI, novel risk scores are needed to predict long­term mortality in this population. AIMS: The study aimed to investigate the value of conventional risk scores in predicting long­term mortality. Additionally, the impact of laboratory parameters on long­term mortality was evaluated. METHODS: Our study included 121 patients who underwent transfemoral TAVI. RESULTS: The mean (SD) logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE), EuroSCORE II, and the Society of Thoracic Surgeons (STS) risk score were 27.4 (9.7), 7.9 (4.6), and 4.6 (2.4), respectively. In­hospital mortality rate was 1.7%. None of the risk scoring systems predicted in­hospital mortality correctly. The STS score corresponded with the mortality rate of approximately 2 months, EuroSCORE II, with 6 months, and logistic EuroSCORE, with 30 months. Male gender (odds ratio [OR], 5.668; 95% CI, 1.055­30.446; P = 0.04) and low albumin levels before TAVI (OR, 0.109; 95% CI, 0.018­0.654; P = 0.02) were found to be the independent predictors of long­term mortality. CONCLUSIONS: Although all conventional risk scores overestimated in­hospital mortality, the STS risk score predicted 2­month, EuroSCORE II, 6­month, and logistic EuroSCORE, 30­month mortality. The independent predictors of long­term mortality were male gender and low blood albumin levels before the TAVI procedure.

Comparing the Diagnostic Value of the C-Reactive Protein to Albumin Ratio With Other Inflammatory Markers in Patients With Stable Angina Pectoris.

Several laboratory parameters have been used to assess inflammatory process and determine cardiovascular risk. The C-reactive protein to albumin ratio (CAR) is a novel marker of inflammation and its clinical importance has not been clearly elucidated in coronary artery disease (CAD). We compared the diagnostic value of CAR with other inflammatory parameters in detecting significant CAD. Patients (n = 421) with stable angina pectoris who underwent coronary angiography for the suspected CAD were included. Neutrophil to lymphocyte ratio (NLR), monocyte to lymphocyte ratio (MLR), platelet to lymphocyte ratio, uric acid, monocyte to high-density cholesterol (HDL-C) ratio, mean platelet volume to lymphocyte ratio (MPVLR), and platelet to mean corpuscular volume (MCV) ratio were measured. Patients with significant CAD had a significantly higher NLR (P = .043), MLR (P = .004), uric acid (P < .001), monocyte to HDL-C ratio (P = .004), and CAR (P < .001) compared to patients without significant CAD. However, MPVLR and platelet to MCV ratio weren't different between 2 groups. The area under the curve (AUC) of CAR was the highest AUC among all inflammatory parameters for predicting significant CAD. Multivariate analysis showed that age (odds ratio [OR]: 1.046, 95% confidence interval [CI], 1.020-1.072, P < .001) and CAR (OR: 1.175, 95% CI, 1.126-1.226, P < .001) were the only independent predictors of significant CAD. In conclusion, CAR had the strongest diagnostic value in detecting significant CAD among the inflammatory parameters evaluated in this study.
