ABSTRACT
BACKGROUND: Arrhythmias and electrocardiographic changes are reported in several noncardiac diseases, including liver cirrhosis (LC). We intended to evaluate the interval from the peak to the end of the electrocardiographic T wave (Tp-e), Tp-e/QTc ratio, and fQRS as presumed markers of arrhythmias in LC. METHODS: In this cross-sectional study, a total of 88 consecutive patients with LC according to clinical, biological, ultrasonographic, or histological criteria and 73 control subjects were enrolled. The severity of cirrhosis was classified according to Pugh-Child's classification and Model for End-Stage Liver Disease (MELD) score. Tp-e interval, Tp-e/QTc ratio, and fQRS rates were measured from the 12-lead electrocardiogram. RESULTS: Tp-e interval, Tp-e/QTc ratio and fQRS rates were significantly increased in parallel to the severity of LC (P < 0.001, P < 0.001, and P = 0.003, respectively). In correlation analysis, Pugh-Child stage showed a significantly positive correlation with Tp-e interval (r = 0.462, P < 0.001), QTc interval (r = 0.373, P < 0.001), Tp-e/QTc ratio (r = 0.352, P < 0.001), and fQRS (r = 0.407, P < 0.001). Furthermore, Tp-e interval (r = 0.414, P < 0.001) and Tp-e/QTc ratio (r = 0.426, P< 0.001) had significant positive correlation with MELD score. CONCLUSIONS: Our study demonstrated that Tp-e interval, Tp-e/QTc ratios, and fQRS rates were significantly increased in parallel to the severity of LC. Thus, these findings may implicate that Tp-e interval, Tp-e/QTc ratio, and fQRS may be novel and useful indicators for prediction of arrhythmias in LC.

Background Previous studies proposed that inflammation, oxidative stress, and impaired endothelial dysfunction have a crucial role in occurrence of saphenous vein graft (SVG) disease (SVGD). The aim of this study was to assess the relationship between monocyte-to-high-density lipoprotein cholesterol (HDL-C) ratio (MHR) and serum albumin (SA) level as readily available inflammatory and oxidative stress markers with the presence of SVGD in patients with a coronary bypass. Methods In this retrospective cross-sectional study, a total of 257 patients (n = 112 SVGD [+] [mean age was 65.3 ± 8.4 years, 75.0% males] and n = 145 SVGD [-] [mean age was 66.5 ± 10.1 years, 74.5% males]) were enrolled. At least one SVG with ≥ 50% stenosis was defined as SVGD. Independent predictors of SVGD were determined by logistic regression analysis. Results White blood cell, neutrophil, monocyte, the age of SVG, and MHR were significantly higher, whereas SA level was significantly lower in patients with SVGD. In regression analysis, neutrophil, age of SVG, SA (odds ratio [OR]: 0.232 [0.156-0.370], p < 0.001), and MHR (OR: 1.122 [1.072-1.174], p < 0.001) remained as independent predictors of SVGD. Moreover, age of SVG showed a significant negative correlation with SA (r = - 0.343, p < 0.001) and a positive correlation with MHR (r = 0.238, p < 0.001). In the receiver-operating characteristic curve analysis, the cutoff value of ≤ 3.75 g/dL for SA has a 73.2% sensitivity and 64.8% specificity and the cutoff value of ≥ 12.1 for MHR has a 71.4% sensitivity and 60.0% specificity for prediction of SVGD. Conclusion Consequently, to the best of our knowledge, this is the first study showing a significant and independent association between SA and MHR with SVGD.

BACKGROUND: Monocyte to high density lipoprotein cholesterol ratio (MHR) is generally understood to be a candidate marker of inflammation and oxidative stress. Therefore, we aimed to assess the association between MHR and aortic elastic properties in hypertensive patients. METHODS: A total of 114 newly-diagnosed untreated patients with hypertension and 71 healthy subjects were enrolled. Aortic stiffness index, aortic strain and aortic distensibility were measured by using echocardiography. RESULTS: Patients with hypertension had a significantly higher MHR compared to the control group (p < 0.001). Also, aortic stiffness index (p < 0.001) was significantly higher and aortic distensibility (p < 0.001) was lower in the hypertensive group. There was a positive correlation of MHR with aortic stiffness index (r = 0.294, p < 0.001) and negative correlation with aortic distensibility (r = -0.281, p < 0.001). In addition, MHR and high sensitivity C-reactive protein have a positive correlation (r = 0.30, p < 0.001). Furthermore, MHR was found to be an independent predictor of aortic distensibility and aortic stiffness index. CONCLUSIONS: In patients with newly-diagnosed untreated essential hypertension, higher MHR was significantly associated with impaired aortic elastic properties.
ABSTRACT
Metabolic syndrome (MetS) as a cluster of several cardio-metabolic components is rapidly growing public-health problem worldwide and significantly associated with poor cardiovascular outcomes. Increased visceral adiposity activates the important pathways connecting low-grade chronic inflammation, oxidative stress and blood coagulation. Recently, platelet to lymphocyte ratio (PLR) has been evidenced as a novel indirect inflammatory marker. Therefore, for the first time, we aimed to investigate the association of PLR with both the presence and severity of MetS. In this cross-sectional study, a total of 1146 participants were enrolled (n = 539 with MetS and n = 607 without MetS). MetS was defined according to NCEP-ATP III criteria. MetS (+) group revealed significantly higher PLR and C-reactive protein (CRP) levels as compared to MetS (-) group (p < 0.05). There was a graded relationship between increasing number of MetS components and PLR (p < 0.05). Also, PLR was positively correlated with CRP level (r = 0.163, p < 0.001). In multivariate regression analysis, PLR [1.121 (1.113-1.135), p < 0.001], CRP [1.044 (1.029-1.060), p < 0.001], and age [1.030 (1.017-1.043), p < 0.001] were remained as independent predictors for the presence of MetS. In conclusion, our findings showed that increased PLR was significantly associated with both the presence and severity of MetS which was linked to systemic inflammation based on the correlation between PLR and CRP. As PLR is an easily available, simple and cheap indirect indicator of inflammation, it can be used in clinical practice as a predictor of MetS.

OBJECTIVE: Infarct-related artery (IRA) patency yields a better outcome in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Red cell distribution width (RDW) emerges as a marker of adverse cardiovascular events and mortality in STEMI. Therefore, we aimed to assess the relationship between IRA patency and RDW value on admission in patients with STEMI undergoing primary PCI. METHODS: A total of 564 patients with STEMI undergoing primary PCI were recruited in this study. According to thrombolysis in myocardial infarction (TIMI) flow grade in the IRA before PCI, the study population was divided into two groups as TIMI 0 or 1 group (occluded IRA, n = 398) and TIMI 2 or 3 group (patent IRA, n = 166). RESULTS: RDW was significantly higher in the occluded IRA group (15.1 ± 1.7 versus 13.4 ± 1.3, p < 0.001) as compared to the patent IRA group. White blood cell (WBC) count, platelet count, creatine kinase-myocardial band (CK-MB) and troponin-I levels were also significantly higher in the occluded IRA group (p < 0.05). Moreover, RDW showed positive correlations with troponin-I (r = 0.397, p < 0.001), CK-MB (r = 0.344, p < 0.001) and WBC (r = 0.219, p < 0.001). In multivariate regression analysis, RDW (OR: 0.483, 95% CI: 0.412-0.567, p < 0.001) and WBC count were significantly and independently associated with IRA patency. CONCLUSIONS: Our findings suggested that RDW value and WBC count on admission were independent predictors of IRA patency in patients with STEMI. As RDW is an easily available, simple and cheap biomarker, it can be used in daily practice as a novel predictor for IRA patency.

Objective Since non-ST segment elevation myocardial infarction (NSTEMI) patients with totally occluded infarct-related artery (TO-IRA) have worse prognosis, it is important to recognize TO-IRA in NSTEMI. Red cell distribution width (RDW) and mean platelet volume (MPV) are novel markers of inflammation and oxidative stress and were associated with poor clinical outcomes in acute coronary syndrome. In the present study, association of RDW and MPV with the presence of TO-IRA in NSTEMI was investigated. Methods Data of 201 consecutive patients who underwent coronary angiography with a diagnosis of NSTEMI were analyzed. Independent predictors of TO-IRA were investigated with logistic regression analysis. Results Sixty-six (32.8%) of the patients had TO-IRA. In patients with TO-IRA, RDW and troponin-T were significantly higher and left ventricular ejection fraction (LVEF) was lower. MPV did not differ between groups. Circumflex (CX) IRA was more common in TO-IRA group. The ROC curve analysis showed that the RDW at a cut-point of 13.95% has 76% sensitivity and 66% specificity in detecting TO-IRA. RDW, troponin-T, LVEF and CX-IRA were independent predictors of TO-IRA in NSTEMI, but MPV was not. Conclusion RDW is a cheap and readily available marker that may have a role to predict TO-IRA in NSTEMI.

BACKGROUND: The risk of syncope and sudden cardiac death due to ventricular arrhythmias increased in patients with aortic stenosis (AS). Recently, it was shown that Tp-e interval, Tp-e/QT, and Tp-e/QTc ratio can be novel indicators for prediction of ventricular arrhythmias and mortality. We aimed to investigate the association between AS and ventricular repolarization using Tp-e interval and Tp-e/QT ratio. METHODS: Totally, 105 patients with AS and 60 control subjects were enrolled to this study. The severity of AS was defined by transthoracic echocardiographic examination. Tp-e interval, Tp-e/QT, and Tp-e/QTc ratios were measured from the 12-lead electrocardiogram. RESULTS: Tp-e interval, Tp-e/QT, and Tp-e/QTc ratios were significantly increased in parallel to the severity of AS (P < 0.001, P = 0.001, and P = 0.001, respectively). Also, it was shown that Tp-e/QTc ratio had significant positive correlation with mean aortic gradient (r = 0.192, P = 0.049). In multivariate logistic regression analysis, Tp-e/QTc ratio and left ventricular mass were found to be independent predictors of severe AS (P = 0.03 and P = 0.04, respectively). CONCLUSIONS: Our study showed that Tp-e interval, Tp-e/QT, and Tp-e/QTc ratios were increased in patients with severe AS. Tp-e/QTc ratio and left ventricular mass were found as independent predictors of severe AS.

OBJECTIVE: The aim of this study was to determine whether the Macruz index (P/P-R segment) could predict the severity of valvular involvement and the success of percutaneous mitral balloon valvuloplasty (PMBV) in patients with mitral stenosis (MS). SUBJECTS AND METHODS: Sixty-one patients with MS eligible for PMBV and 72 healthy subjects (61 females and 11 males) with sinus rhythm were enrolled into this study. PMBV was performed in all patients using a percutaneous transseptal antegrade approach and a multitrack balloon technique. The P/P-R segment ratio and echocardiographic variables were measured before and 48-72 h after the procedure. The optimal cutoff point for differences in the Macruz index to determine clinical success was evaluated by receiver operating characteristic analysis by calculating the area under the curve as giving the maximum sum of sensitivity and specificity for the significant test. RESULTS: In the patient group (mean age 42.9 ± 11.1 years), the preprocedural Macruz index was significantly higher than in the control group (2.79 ± 1.03 vs. 1.29 ± 0.11; p < 0.001). In the successful-procedure group (n = 53), the mean postindex value was significantly lower (2.12 ± 0.71 vs. 2.81 ± 1.0, p = 0.020), and the decrease in the Macruz index was significantly higher than in the unsuccessful-procedure group (p = 0.007). An index decrease of 0.105 was the best cutoff value to distinguish the successful-PMBV group from the unsuccessful- PMBV group (area under the curve = 0.888, 95% confidence interval 0.788-0.988, p < 0.001). CONCLUSION: The Macruz index was significantly higher in patients with MS compared to healthy subjects. A greater decrease in the Macruz index was associated with a successful PMBV.

OBJECTIVES: Limited data are available regarding cardiac arrhythmias in vitamin D (VitD) deficiency. Therefore, we aimed to assess whether atrial electromechanical delay (AEMD) measured by tissue Doppler imaging (TDI), which is an indicator for atrial fibrillation (AF) development, is prolonged in patients with VitD deficiency as compared to the control group. The effect of vitD replacement on AEMD was also evaluated. METHODS: In this prospective study a total of 28 VitD-deficient and 56 age-, gender-, and BMI-matched VitD-sufficient healthy participants were enrolled. P-wave dispersion (PWd) was calculated on the 12-lead electrocardiogram. Both intra- and inter-AEMD were calculated by TDI. Measurements were performed at baseline in both groups and were repeated after 6-month replacement therapy in subjects with vitD deficiency. RESULTS: PWd and inter- and left intra-AEMD were significantly prolonged in patients with VitD deficiency compared to the control group (P < 0.001). While serum 25(OH)D levels were significantly and negatively correlated with left intra-AEMD (r = -0.657, P < 0.001), there was a positive correlation between serum 25(OH)D level and PWd (r = 0.523, P < 0.001). The serum 25(OH)D level was found as the independent predictor of the both left intra- and inter-AEMD in the multivariate linear regression analysis (ß:-0.552, P < 0.001 and ß:-0.555, P < 0.001, respectively). The serum 25(OH)D level was significantly increased after replacement therapy. While inter-AEMD was significantly decreased (P = 0.013), there was no change in PWD and left and right intra-AEMD (P > 0.05) following replacement therapy. CONCLUSION: PWd and left intra- and inter-AEMD are increased in patients with VitD deficiency. The serum 25(OH)D level was found as an independent predictor for AEMD in patients with VitD deficiency. Also a significant decrement was observed in inter-AEMD following vitD replacement therapy. Studies with longer follow-up are needed to investigate whether vitD-deficient patients with prolonged AEMD develop clinical arrhythmia and vitD replacement reduces the risk of atrial arrhythmias.

BACKGROUND: Vitamin D is known for its effect in calcium and bone homeostasis. There is an increasing evidence for health benefits accomplished by activated vitamin D that go beyond these classical functions. Previous studies have suggested that lower vitamin D levels are associated with increased cardiovascular disease risk. Therefore, we aimed to evaluate relationship between vitamin D levels and extent and severity of coronary artery disease. MATERIALS AND METHODS: A total of 746 patients in whom coronary angiography was performed between August 2012 and July 2013 were enrolled in this study. Serum vitamin D levels were measured, and patients were grouped according to their serum vitamin D levels (vitamin D <20 ng/mL (n = 602) Group 1 versus >20 ng/dL (n = 144) Group 2). Gensini score system was used to evaluate the association between serum vitamin D levels and severity and extent of coronary artery disease. RESULTS: There was no significant difference between the groups in terms of baseline characteristics and demographic characteristics. Mean serum vitamin D levels of all patient cohort was 15.54 ± 7.46 ng/mL. Group 1 and Group 2 had an average serum vitamin D levels of 12.6 ± 3.3 ng/mL and 27.5 ± 7.8 ng/mL, respectively. Gensini score for all cohort was 26.25 ± 34.32. Group 1 had an average Gensini score of 26.4 ± 35.7; on the other hand, Gensini score was 25.5 ± 27.5 in Group 2 (P = 0.097). CONCLUSIONS: This study failed to demonstrate significant relationship between serum vitamin D levels and the severity and extent of coronary artery disease. Further studies with more participation and homogenous groups with comparable individual and environmental features are needed to evaluate the association of serum vitamin D levels and cardiovascular diseases.

OBJECTIVES: Mitral annular calcification (MAC) and atherosclerosis are similar in regard to risk factors and pathogenesis. Increased platelet-to-lymphocyte ratio (PLR) has been shown to be associated with atherosclerotic diseases in previous studies. In this study, we aimed to show the association of PLR levels with the presence of MAC. DESIGN: A total of 1060 patients [n = 704 MAC (+), and n = 356 MAC (-)] who were admitted to our cardiology department were enrolled between January 2014 and December 2014. Demographic, clinical, and laboratory parameters of all participants were recorded. PLR was calculated from the complete blood count. RESULTS: The MAC (+) group comprised of those older in age and having a higher rate of hypertension. The mean PLR value was also significantly higher in the MAC (+) group, as compared to that in the MAC (-) group (129.1 ± 32.2 vs 103.5 ± 23.8, p < 0.001). There was a statistically significant and positive correlation between the neutrophil-to-lymphocyte ratio (NLR) and PLR (r = 0.644, p < 0.001). Age, hypertension, mean platelet volume, NLR, and PLR (OR: 1.109, 95% CI: 1.101-1.123, p < 0.001) were independently associated with the presence of MAC. CONCLUSIONS: Our results demonstrated that the PLR was significantly increased in patients with MAC, and that the PLR was independently associated with the presence of MAC.

BACKGROUND: There are few prospective data available for establishing a standard diuretic administration regimen for patients with acute decompensated heart failure (ADHF). We aimed to assess the safety and efficacy of three regimens of furosemide administration in patients with ADHF with regard to diuresis, renal functions, and in-hospital outcomes. METHODS: A total of 43 patients who presented with ADHF were randomized into three groups: (a) continuous infusion (cIV) of 160 mg furosemide for 16 h/day (n = 15); (b) bolus injections (bI) of 80 mg furosemide twice a day (n = 14); (c) and administration of 160 mg furosemide plus hypertonic saline solution (HSS) as an infusion for 30 min once a day (n = 14). All regimens were continued for 48 h. Study endpoints were negative fluid balance assessed by loss of body weight, change in the serum creatinine (baseline to 48 h and baseline to compensated state), and length of hospitalization. RESULTS: There was no significant difference in the mean change in serum creatinine level at the end of 48 h between groups (p = 0.08). There was also no significant difference among groups regarding loss of body weight (p = 0.66). A significantly shorter hospitalization was observed in patients treated with HSS compared with the other groups (cIV group 6.6 ± 3.4 days vs. bI group 7.9 ± 4.1 days vs. HSS group 3.7 ± 1.3 days; p < 0.01). CONCLUSION: All three furosemide regimens have similar renal safety and efficacy measures. However, administration of furosemide plus HSS may be the preferred diuretic strategy because of its shorter hospital stay.

OBJECTIVE: Mitral annular calcification (MAC) and atherosclerosis are similar in regard to risk factors and pathogenesis. Increased red blood cell distribution width (RDW) has been shown to be associated with atherosclerotic diseases. However, no data evaluating the association of MAC with RDW has been available. The aim of this cross-sectional study was to investigate the relationship between MAC and RDW among patients with various cardiovascular risk factors. METHODS: A total of 623 patients (MAC-positive group: n=413; control group: n=210) admitted to our cardiology outpatient clinics were enrolled between March and November 2014. Demographic, clinical, and laboratory parameters of all participants were recorded. RDW was analyzed from complete blood samples of study participants. RESULTS: Patients in MAC-positive group showed older age and higher rate of hypertension. Mean RDW value was significantly higher in MAC-positive group, compared to control group (15.3±1.4% vs. 13.9±1.4%, p<0.001). In Pearson correlation analysis, statistically significant and positive correlation was determined between neutrophil-lymphocyte ratio and RDW (r=0.284, p<0.001). In multivariate logistic regression analysis, age (OR: 1.041, p<0.001), hypertension (OR: 1.540, p=0.039), and RDW (OR: 5.351, p<0.001) were determined as independent predictors of MAC. CONCLUSION: RDW levels were significantly increased in patients with MAC, and RDW was determined as an independent predictor for presence of MAC. Therefore, increased RDW can be used as a marker of continuing inflammatory process in MAC patients.

OBJECTIVE: As an indicator of variability in circulating erythrocyte size, red cell distribution width (RDW) is linked to chronic inflammation. The association of rheumatic heart valve stenosis and inflammation is also well-known. This study aimed to assess the relationship between RDW and presence and severity of rheumatic mitral valve stenosis (RMVS). METHODS: A total of 417 consecutive patients with RMVS, and 81 age- and -gender matched healthy control subjects were included in the study between February 2009 and April 2014. Transthoracic echocardiography and demographic characteristics were recorded for all participants. RESULTS: Baseline characteristics were similar in the two groups. However, median RDW was significantly higher in patients with RMVS compared to control group (14.4% [11.3-19.6] vs. 13.6% [11.6-18.1], p<0.001). Additionally, both median C-reactive protein (CRP) and neutrophil-lymphocyte ratio (NLR) were also higher in the RMVS group; (6.1 [0.4-24.2] vs. 3.6 [0.3-15.3] mg/dl, p=0.001 for CRP, and 2.8 [0.4-10.6] vs. 2.1 [0.7-5.7], p<0.001 for NLR respectively). In regression analysis, RDW (OR: 1.504, p=0.005), CRP (OR: 1.139, p=0.008), NLR (OR: 1.528, p=0.018) and left atrial diameter (OR: 1.218, p<0.001) were found as independent predictors of the presence of RMVS. Furthermore, there was a significant positive correlation between CRP (r=0.140, p=0.007) and NLR levels (r=0.276, p<0.001) with RDW levels. Furthermore, we determined that RDW levels increased in parallel with severity of mitral stenosis (mild, moderate and severe) [13.7% (12.9-14.8), 14.4% (13.4-15.4), 14.8% (13.6-16.3), p<0.001, respectively]. CONCLUSION: The study demonstrated significantly higher RDW in patients with RMVS. Furthermore, RDW independently predicted the presence of RMVS. RDW is an easily available marker, and because of its correlation with common inflammatory indicators may also be a sign of chronic inflammatory continuum in patients with RMVS.

Atrial fibrillation (AF) is one of the most encountered arrhythmias in clinical practice. It is also estimated that the absolute AF burden may increase by greater than 60% by 2050. It is inevitable that AF will become one of the largest epidemics in the world and may pose a major health problem for countries. Although AF rarely causes mortality in the acute period, it causes a significant increase in mortality and morbidity, including a fivefold increase in the risk of stroke, a twofold increase in dementia, and a twofold increase in myocardial infarction in the chronic period. Despite all the advances in the treatment of AF, it is better understood day by day that preventing AF may play a key role in reducing AF and its related complications. Modification of the main modifiable factors such as quitting smoking, abstaining from alcohol, changing eating habits, and exercise seems to be the first step in preventing AF. The strict adherence to the treatment process of secondary causes predisposing to AF such as DM, hypertension, obesity, and sleep apnea is another step in the prevention of AF. Both an individual approach and global public health campaigns can be highly beneficial to reduce the risk of AF. In this review, we aimed to summarize the current evidence on the relationship between modifiable risk factors and AF, and the impact of possible interventions on these factors in preventing or reducing the AF burden in the light of recently published guidelines and studies.

Acute stent thrombosis (AST) is associated with increased morbidity and mortality. The main aim of this study was to evaluate the prognostic value of the systemic immune-inflammation index (SII) and C-reactive protein (CRP) to albumin ratio (CAR) in predicting AST and high SYNTAX score in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). The criteria of the Academic Research Consortium were used to determine definite stent thrombosis. A total of 2077 consecutive patients with ACS undergoing PCI were retrospectively enrolled. Platelet, white blood cell and neutrophil counts, as well as SII, CRP, CAR, and peak cardiac troponin I (cTnI) values were significantly higher, whereas the lymphocyte count and albumin values were significantly lower in the AST (+) group compared with the AST (-) group (P < .05). SYNTAX score showed significant positive correlations with SII (r = .429, P < .001) and CRP (r = .402, P < .001). Multivariate logistic regression analysis showed that SII and CAR, as well as age, diabetes mellitus, stent length, and peak cTnI are independent predictors of AST and high SYNTAX score. In conclusion, the SII and CAR are simple, relatively cheap, and reliable inflammatory biomarkers that can predict AST and high SYNTAX scores in ACS.

BACKGROUND: Despite advances in therapeutic management of patients with heart failure, there is still an increasing morbidity and mortality all over the world. In this study, we aimed to present the 3-year follow-up outcomes of patients included in the Journey HF-TR study in 2016 that has evaluated the clinical characteristics and management of patients with acute heart failure admitted to the hospital and present a national registry data. METHODS: The study was designed retrospectively between November 2016 and December 2019. Patient data included in the previously published Journey HF-TR study were used. Among 1606 patients, 1484 patients were included due to dropout of 122 patients due to inhospital death and due to exclusion of 173 due to incomplete data. The study included 1311 patients. Age, gender, concomitant chronic conditions, precipitating factors, New York Heart Association, and left ventricular ejection fraction factors were adjusted in the Cox regression analysis. RESULTS: During the 3-year follow-up period, the ratio of hospitalization and mortality was 70.5% and 52.1%, respectively. Common causes of mortality were acute decompensation of heart failure and acute coronary syndrome. Angiotensin receptor blockers, betablockers, statin, and sacubitril/valsartan were found to reduce mortality. Hospitalization due to acute decompensated heart failure, acute coronary syndrome, lung diseases, oncological diseases, and cerebrovascular diseases was associated with the increased risk of mortality. Implantation of cardiac devices also reduced the mortality. CONCLUSIONS: Despite advances in therapeutic management of patients with heart failure, our study demonstrated that the long-term mortality still is high. Much more efforts are needed to improve the inhospital and long-term survival of patients with chronic heart failure.

OBJECTIVE: To evaluate the prognostic value of preprocedural CHA2DS2-VASc [congestive heart failure, hypertension, age ≥75 years (doubled), diabetes mellitus, previous stroke or transient ischemic attack (TIA) (doubled), vascular disease, age 65-74 years, female gender] score in predicting high SYNTAX (Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery) score and in-hospital mortality for non-atrial fibrillation (AF) patients presenting with non-ST elevation myocardial infarction (NSTEMI). The CHA2DS2-VASc score used to determine thromboembolic risks in AF was recently reported to predict major adverse clinical outcomes in patients with the acute coronary syndrome, irrespective of AF. METHODS: A total of 906 patients with a diagnosis of NSTEMI who underwent coronary angiography were retrospectively enrolled and divided into three groups according to their SYNTAX scores (low, intermediate, and high). The CHA2DS2-VASc score of each patient was calculated. RESULTS: SYNTAX score had a significant positive correlation with the CHA2DS2-VASc score (r=0.320; p<0.001) in the Spearman correlation analysis. The CHA2DS2-VASc score [Odds ratio, 1.445; 95% confidence interval (CI), 1.268-1.648, p<0.001], left ventricular ejection fraction, creatinine, C-reactive protein, and high-density and low-density lipoprotein cholesterol levels were demonstrated to be independent predictors of high SYNTAX score. The CHA2DS2-VASc score [Hazard ratio (HR), 1.867; 95% CI: 1.462-2.384; p<0.001], the SYNTAX score (HR, 1.049; p=0.003), and age (HR, 1.057; p=0.002) were independently associated with higher risk of in-hospital mortality in a multiple Cox-regression model. Kaplan-Meier survival curves stratified by the CHA2DS2-VASc score (<4 vs. ≥4) also showed that higher CHA2DS2-VASc scores were associated with higher in-hospital mortality. CONCLUSIONS: In non-AF patients with NSTEMI, CHA2DS2-VASc and SYNTAX scores are useful for prognosis assessment and can be used to identify patients at higher risk for in-hospital mortality.

Background: The use of warfarin and aspirin in combination is restricted to limited patients under relevant guidelines. Aims: To evaluate the prevalence of the inappropriate combination of aspirin and warfarin therapy in daily practice and its risks. Study Design: Cross-sectional study. Methods: The awareness, efficacy, safety, and time in the therapeutic range of warfarin in the Turkish population study is a multi-center observational study that includes 4987 patients using warfarin for any reason between January 1, 2014, and December 31, 2014. To determine the prevalence of inappropriate combination use in daily practice, all patients who had a history of atherosclerotic disease (ischemic heart disease, peripheral artery disease) or cerebrovascular disease (n=1498) were excluded. The data of 3489 patients were analyzed. We defined inappropriate combination as all patients who received aspirin and warfarin regardless of the indication for warfarin use, under the direction of the European Society of Cardiology guideline recommendation. Results: The mean age of patients was 59.2±13.8 years (41.8% male). The prevalence of the inappropriate use of warfarin and aspirin combination was 20.0%. The prevalence of combination therapy in patients with a primary indication for mechanical heart valve, non-valvular atrial fibrillation, and other reasons was 20.5%, 18.7%, and 21.0%, respectively. Multivariate logistic regression analysis revealed that age (odds ratio, 1.009; 95% confidence interval, 1.002-1.015; p=0.010), heart failure (odds ratio, 1.765; 95% confidence interval, 1.448-2.151; p<0.001), smoking (odds ratio, 1.762; 95% confidence interval, 1.441-1.153; p<0.010), chronic kidney disease (odds ratio, 2.057; 95% confidence interval, 1.494-2.833; p<0.001), and deep vein thrombosis (odds ratio, 0.463; 95% confidence interval, 0.229-0.718; p=0.001) were independent predictors of combination therapy (r2=0.66). The mean time in therapeutic range of patients receiving combination therapy was significantly lower than in those on warfarin monotherapy (51.6±27.05 vs. 54.7±23.93; p=0.006). Overall, 19.4% (n=677) of patients had a bleeding event (major bleeding 13.0%, n=88) within a year. Percentages of patients with combination therapy were significantly higher in patients with major bleeding than in patients without major bleeding (29.5% vs. 19.7%; p=0.023). Conclusion: Our study demonstrated that 20.0% of patients taking warfarin use concomitant aspirin inappropriately in daily practice. Patients receiving aspirin with warfarin were demonstrated to have more comorbidities, lower time in therapeutic range levels, and higher bleeding rates.

The CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, previous stroke, vascular disease, age 65-74 years, female gender) score is used to estimate thromboembolic risk in atrial fibrillation (AF). Its usefulness in predicting in-stent restenosis (ISR) is unknown. We evaluated the predictive value of the CHA2DS2-VASc score in AF-free patients who have undergone stent implantation. A total of 1350 patients who underwent coronary angiography and successful bare-metal stent implantation were analyzed. The CHA2DS2-VASc score was calculated before percutaneous coronary intervention, and the association between the score and ISR was investigated. Patients (n = 700; mean age: 61.4 [8.7] years, 63% men) were divided in 2 subgroups according to the presence of ISR; 265 of 700 patients had ISR. Mean CHA2DS2-VASc score was significantly higher in the ISR (+) group than the ISR (-) group (3.7 [1.8] vs 2.1 [1.4], P < .001). According to multivariate logistic regression analysis, diabetes, hyperlipidemia, smoking, stent length, and CHA2DS2-VASc score were independent predictors of ISR. In conclusion, the CHA2DS2-VASc score may be useful as a new and simple tool to predict ISR.
