RESUMO
INTRODUCTION AND OBJECTIVES: D-dimers are a determinant of hypercoagulable state and have been found to be related to acute coronary syndromes. We aimed to establish the association between increased D-dimer levels and coronary artery disease (CAD) severity using SYNTAX Score (SS) II in patients with ST elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI). METHODS: This retrospective study included 300 consecutive patients (81.7% males, mean age 55±12 years) with STEMI who underwent a primary PCI. Patients were divided into two groups according to their median SSII [SSII<25 as a low group (n=151) and SSII≥25 as a high group (n=149)]. Blood samples for D-dimers and the other biochemical parameters were obtained from each patient at admission. RESULTS: When compared with the low SSII group, frequency of female gender, no-reflow phenomenon, D-dimer levels, thrombus score, creatine kinase MB and troponin were significantly higher, whereas left ventricular ejection fraction (LVEF) and glomerular filtration rate (GFR) were lower in the high SSII group (p<0.05, for all). D-dimer levels, thrombus score, LVEF, GFR and no-reflow phenomenon were independent predictors of CAD severity (p<0.05, for all). Receiver operating characteristic curve analysis showed that the D-dimer cut-off value for predicting the severity of CAD was 0.26 µg/ml (69.8% sensitivity and 65.6% specificity, p<0.001). CONCLUSION: Increased D-dimer levels are associated with the severity of CAD based on Syntax Score II, in patients with STEMI who successfully underwent revascularization with a primary PCI.

BACKGROUND: Increasing evidence suggests a relationship between vitamin D (VD) insufficiency and cardiovascular disease. AIM: We aimed to investigate the association between serum 25-hydroxyvitamin D (25-OH VD) with coronary tortuosity (CT) in patients with normal or near-normal (< 40% stenosis) coronary arteries. METHODS: The present study was cross-sectional and observational. We enrolled 356 consecutive patients who had undergone coronary angiography for suspected ischaemic heart disease and were found to have normal or near-normal coronary arteries. Patients were categorised as VD insufficient (< 30 ng/mL) or VD sufficient (≥ 30 ng/dL). CT was defined as the presence of ≥ three bends (defined as ≥ 45° change in vessel direction) along the main trunk of at least one coronary artery, present both in systole and in diastole. RESULTS: The study populations were divided into two groups according to the presence of CT: patients with CT (n = 103, 29%) and patients without CT (NCT; n = 253, 71%). CT is more frequently seen in elderly women and is positively correlated with hypertension. The incidence of VD insufficiency was significantly higher in the CT group (n = 46, 45%) than in the NCT group (n = 90, 36%; p = 0.005). In further multivariate logistic regression analyses, adjustment for major clinical parameters affecting CT showed statistically significant correlations between 25-OH VD and CT (odds ratio = 0.77, 95% confidence interval 0.66-0.98, p = 0.006). CONCLUSIONS: Vitamin D insufficiency was independently associated with coronary tortuosity.

OBJECTIVE: Thyroid disease is a common endocrine disease with important effects on the cardiovascular system. As an adaptive response to myocardial ischemia, coronary collateral circulation (CCC) plays an important role in obstructive coronary artery disease (CAD). The association between serum thyroid hormone levels and development of CCC was investigated in the present study. METHODS: In total, 430 consecutive patients who underwent coronary angiography procedure and had documented total occlusion in at least 1 major coronary artery were investigated retrospectively. Degree of CCC was classified according to Cohen-Rentrop method. Serum free triiodothyronine (FT3), free thyroxine (FT4) and thyroid-stimulating hormone (TSH) were assessed by the chemiluminescence immunoassay technique. RESULTS: In spite of diabetes mellitus (p=0.019), smoking (p<0.001), and TSH (p<0.001), FT3 (p<0.001), FT4 (p=0.015), and subclinical hypothyroidism (SCH) (p<0.001) ratios were significantly different between groups. In regression analysis, SCH (p=0.024), DM (p=0.021), smoking (p<0.001), and heart failure (p=0.029) were independent predictors of poor CCC development in multivariate model 1. When regression analyses were performed based on multivariate model 2, TSH (p<0.001), FT3 (p<0.001), heart failure (p=0.022), smoking (p<0.001), and hyperlipidemia (HPL) (p=0.046) were independent predictors of poor CCC development. CONCLUSION: In addition to traditional risk factors, SCH, higher serum TSH, and lower FT3 levels were associated with development of poor CCC in patients with obstructive CA.

BACKGROUND: CHADS2 and CHA2DS2-VASc scores are widely used in clinical practice and include similar risk factors for the development of coronary artery disease (CAD). It is known that the factors comprising the newly defined CHA2DS2-VASc-HSF score promote atherosclerosis and are associated with severity of CAD. AIM: To investigate the association of the CHA2DS2-VASc-HSF score with the severity of CAD as assessed by SYNTAX score (SxS) in patients with ST segment elevation myocardial infarction (STEMI). METHODS: A total of 454 consecutive patients with STEMI (males 79%, mean age 57.3 ± 12.9 years), who underwent primary percutaneous coronary intervention were included in our study. The patients were divided into three groups according to the SxS tertiles: low SxS group (SxS < 14; 151 patients), intermediate SxS group (SxS 14-20; 152 patients), and high SxS group (SxS ≥ 21; 151 patients). RESULTS: The CHADS2, CHA2DS2-VASc, and CHA2DS2VASc-HSF scores were found to be significantly different among the SxS groups (p < 0.001, p < 0.001, and p < 0.001). After multivariate analysis, the CHA2DS2-VASc-HSF score was associated with high SxS (odds ratio [OR] 1.258, 95% confidence interval [CI] 1.026-1.544; p = 0.028) together with age (OR 1.032, 95% CI 1.013-1.050; p = 0.001) and ejection fraction (OR 0.927, 95% CI 0.901-0.955; p < 0.001). CONCLUSIONS: A newly diagnosed CHA2DS2-VASc-HSF score predicts the severity of atherosclerosis in patients with STEMI.

Although mean platelet volume (MPV) is an independent correlate of impaired angiographic reperfusion and 6-month mortality in ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (pPCI), there is less data regarding the association between platelet distribution width (PDW) and in-hospital major adverse cardiovascular events (MACEs). A total of 306 patients with STEMI pPCI were evaluated. No reflow was defined as a post-PCI thrombolysis in myocardial infarction (TIMI) flow grade of 0, 1, or 2 (group 1). Angiographic success was defined as TIMI flow grade 3 (group 2). The values of MPV and PDW were higher among patients with no reflow. In-stent thrombosis, nonfatal myocardial infarction, in-hospital mortality, and MACEs were significantly more frequent among patients with no reflow. In multivariate analysis, PDW, MPV, high-sensitivity C-reactive protein, and glucose on admission were independent correlates of in-hospital MACEs. Admission PDW and MPV are independent correlates of no reflow and in-hospital MACEs among patients with STEMI undergoing pPCI.

Neutrophil/lymphocyte ratio (NLR) has been proposed as a prognostic marker to determine systemic inflammatory response and atherosclerosis. Our aim was to determine the relationship between NLR and development of coronary collateral circulation (CCC) in patients with stable coronary artery disease (CAD). A total of 521 consecutive patients with stable CAD who underwent coronary angiography and documented total occlusion in one of those major coronary arteries were included in this study. Levels of fasting blood glucose, white blood cell, and NLR were significantly higher in patients with poor collateral than in those with good collateral. After multivariate analysis, high level of NLR was an independent predictor of CCC together with levels of fasting blood glucose. The receiver-operating characteristic analysis provided a cutoff value of 2.75 for NLR to predict poor CCC with 65% sensitivity and 68% specificity. We demonstrated an independent association between levels of NLR and development of CCC in patients with stable CAD.

BACKGROUND: Permanent cardiac pacemakers (PCM) are accepted as the most effective treatment for symptomatic bradyarrhythmias. Serum uric acid (UA) levels are associated with various inflammatory markers, oxidative stress, and endothelial dysfunction. This study aimed to investigate the association between serum UA and ventricular pacing threshold (VPT) levels in patients who underwent permanent pacemaker implantation. MATERIALS AND METHODS: We retrospectively analyzed a total of 198 patients who underwent PCM implantation for indications such as symptomatic bradycardia without a reversible etiology and high-degree and complete atrioventricular block. RESULTS: VPT values were found to correlate with serum UA levels (r=0.591, p<0.001), high sensitivity C-reactive protein (hs-CRP) levels (r=0.505, p<0.001), and ventricular impedance (r=0.220, p=0.016). The serum UA levels and hs-CRP levels were also correlated (r=0.691, p<0.001). To identify independent risk factors for VPT values, a multivariate linear regression model was conducted, and serum UA levels (ß=0.361, p=0.001), hs-CRP levels (ß=0.277, p=0.012), and impedance values (ß=0.207, p=0.011) were found to be independent risk factors for VPT. CONCLUSION: In the present study, VPT values at the time of implantation and at the 30th day were increased in patients with high serum UA levels. To further extend the life of pacemakers, as well as other factors that affect threshold values, serum UA levels should be noted.

We aimed to elucidate the relationship between mild to moderate renal impairements and burden of atherosclerosis in patients with acute coronary syndrome (ACS). A total of 380 patients with ACS were included in the study. Gensini and SYNTAX scores were also calculated. Kidney function was classified based on estimated glomerular filtration rate (eGFR) into stage 1: eGFR >90, stage 2: 60 to 89, and stage 3: 30 to 60 mL/min per 1.73 m(2). Gensini and SYNTAX scores were higher in stages 2 and 3 than in stage 1. Also, the number of diseased vessels, number of critical lesions (>50 and 70%), left main disease, and number of total occlusion vessels were higher in stages 2 and 3 than in stage 1. Multivariate linear regression analysis demonstrated that a decreased eGFR was an independent risk factor for SYNTAX and Gensini scores together with age and male gender.

N-terminal pro-brain natriuretic peptide (NT-proBNP) is an excellent biomarker to diagnose left ventricular (LV) dysfunction. LV myocardial performance index (MPI-Tei index) is commonly used as a measure of combined systolic and diastolic function. We aimed to investigate the relationship between NT-proBNP and tissue Doppler derived MPI in newly diagnosed hypertensive patients with preserved LV ejection fraction (LVEF). We studied 236 patients with newly diagnosed HT (mean age; 52.9 ± 5.2 years). Echocardiographic examination was performed in all patients. LV mass index (LVMI) was calculated. Conventional Doppler indices (E and A waves) were recorded. The MPI value was obtained from the tissue Doppler derived ejection time, isovolumic contraction and relaxation times. The patients were divided into two groups according to the median NT-proBNP value (NT-proBNPlow group <114 pg/ml and NT-proBNPhigh group ≥114 pg/ml). Patients with NT-proBNPhigh were older and had higher levels of glucose and creatinine, lower E/A ratio and higher LVMI and MPI values than patients with NT-proBNPlow. However, LVEF were similar among the groups. Multiple linear regression analysis showed that NT-proBNP was independently associated with age, LVMI, MPI and E/A ratio. Increased NT-proBNP level was independently associated with impaired myocardial performance index in newly diagnosed hypertensive patients with preserved LVEF.

Serum uric acid (SUA) levels have been proposed as a biomarker of coronary artery disease (CAD) and coronary collateral circulation (CCC). We investigated the association between SUA levels and development of CCC in patients with stable CAD. Consecutive patients (n = 480) with stable CAD who underwent coronary angiography and documented total occlusion in 1 of the major coronary arteries were included in this study. Levels of fasting blood glucose, white blood cell (WBC), creatinine, platelet count, and SUA were significantly higher in patients with poor CCC than in those with good CCC. After multivariate analysis, high levels of SUA were an independent predictor of CCC together with levels of fasting blood glucose and WBC. The receiver-operating characteristic analysis provided a cutoff value of 5.65 mg/dL for SUA to predict poor CCC with 60% sensitivity and 66% specificity. High levels of SUA may be associated with poor CCC in patients with stable CAD.

We studied 403 consecutive patients with non-ST-segment elevation myocardial infarction (NSTEMI). This population was divided into tertiles according to the SYNTAX score (SXscore). The high SXscore group was defined as an SXscore ≥13, and the low SXscore group as an SXscore <13. The total bilirubin (sTB) and direct bilirubin levels of patients were significantly higher in the high SXscore group (P = .001 and P = .007, respectively). There was a correlation between sTB and SXscore (r = .495; P = .005). On multivariate linear regression analyses, age (ß = .100; P = .041), sTB levels (ß = .171; P = .005), low-density lipoprotein cholesterol (ß = .121; P = .014), and troponin-I (ß = .124; P = .011) remained independent correlates of high SXscore. The mean follow-up period was 18.2 months. All-cause mortality rate was higher in the high SXscore group but did not reach significance (P = .058). In conclusion, high sTB level is independently associated with severity of coronary artery disease in patients with NSTEMI. However, no association was found with long-term mortality.

BACKGROUND AND OBJECTIVES: We have intended to investigate the influence of the timing of invasive procedures on all-cause mortality, recurrent myocardial infarction (MI), re-hospitalization due to cardiac causes and left ventricular function over a 3-month period among patients with Non-ST-elevation myocardial infarction (NSTEMI). SUBJECTS AND METHODS: A total of 131 NSTEMI patients with moderate-high Thrombolysis in Myocardial Infarction risk scores, who had been admitted to our department between July 2011-December 2011 were included in our study. They had been randomized into 2 groups according to the timing of the percutaneous coronary intervention (PCI). Patient undergoing PCI in the first 24 hours of hospitalization were named the "Early Invasive Group" and those undergoing PCI between 24-72 hours of hospitalization were named the "Delayed Invasive Group". All patients were followed up for 3 months. RESULTS: Third month left ventricular ejection fraction (LVEF) values were higher in the early invasive group (59.9±6.0% vs. 54.1±8.7%; p<0.001). Recurrent MI rates were lower in the early invasive group (2.9% vs. 14.5%; p=0.016). Similarly, hospitalization rates due to cardiac events were lower in the early invasive group (8.7% vs. 30.6%; p=0.001). All cause mortality appeared to be lower in the early invasive group, although not to a statistically significant degree (0% vs. 4.8%; p=0.065). CONCLUSION: The early invasive strategy appears to be more effective for the reduction of recurrent MI, re-hospitalization due to cardiac events, and the preservation of 3rd month LVEF in patients with moderate-high risk NSTEMI when compared to a delayed invasive strategy.
RESUMO
OBJECTIVES: Several studies have evaluated a relationship between increased red cell distribution width (RDW) and morbidity and mortality of acute coronary syndrome (ACS). In this study, we aimed to investigate the association of serum RDW levels and development of coronary collateral vessel (CCV) in patients with ACS. STUDY DESIGN: We evaluated 226 patients with ACS in this prospective and cross-sectional study. Traditional laboratory and clinical parameters and serum RDW levels were measured on admission. All patients underwent coronary angiography on the first day after admission and patients with >80% stenosis were included in the study. The CCV was graded according to the Rentrop scoring system, and a Rentrop grade 0 was accepted as no CCV development (Group 1), while Rentrop grades 1-2-3 were accepted as presence of CCV development (Group 2). RESULTS: Only levels of RDW were significantly higher in Group 1 than in Group 2 (Group 1 RDW 14.6±1.9, Group 2 RDW 14.1±1.4, p=0.02). The predictive value of serum RDW level for absence of collaterals (sensitivity of 58% and specificity of 54%, area under the receiver operating characteristic (ROC) curve = 0.573) was 13.90. CONCLUSION: We found that high levels of RDW were associated with absence of CCV in patients with ACS.

OBJECTIVES: We evaluated the relationship between serum gamma-glutamyltransferase (GGT) levels and the burden of atherosclerosis in patients with acute coronary syndrome (ACS). STUDY DESIGN: This study involved 180 patients (139 male, 41 female; mean age 63±11 years) with the diagnosis of ACS (non-ST elevation myocardial infarction and unstable angina) who underwent coronary angiography on the first day after hospital admission. The burden of atherosclerosis was assessed by the number of involved vessels, and the Gensini and Syntax scores. Serum GGT levels were measured by enzymatic caloric test. RESULTS: Patients with high Syntax scores (>=33) were more frequently diabetic, hypertensive, and had higher GGT and creatinine levels compared to the patients with low Syntax scores (<=23). Similarly, patients with >=3 diseased vessels were more frequently diabetic, hypertensive, and smokers. In addition, these patients were older and had higher serum glucose, urea and GGT levels. Correlation analysis revealed that the level of GGT was significantly associated with Gensini and Syntax scores, number of diseased vessels, and the number of critical lesions (r=0.378 p<0.001, r=0.301 p<0.001, r=0.159 p=0.036, r=0.355 p<0.001, respectively). Multivariate linear regression analysis demonstrated that increased GGT level was an independent risk factor for high Gensini and Syntax scores (p=0.029 and p=0.035, respectively), together with age (p=0.001 and p=0.002, respectively) and serum glucose levels (p=0.017 and p=0.012, respectively). CONCLUSION: Serum GGT levels on admission are associated with increased burden of atherosclerosis in patients with ACS. This may account for the cardiovascular outcomes associated with increased GGT levels.

OBJECTIVE: Elevated mean platelet volume (MPV) has been proposed as a risk factor for coronary artery disease (CAD) and is associated with poor clinical outcome in acute coronary syndrome (ACS). We aimed to evaluate the association of MPV with presence of coronary collateral vessel (CCV) in patients with ACS. METHODS: A total of 417 patients with ACS were included in the study. All patients underwent coronary angiography on the first day after admission and patients with a greater than or equal to 80% obstruction in at least one epicardial coronary artery were included in the study. The CCVs are graded according to the Rentrop scoring system and a Rentrop grade 0 was accepted as no CCV development (group 1), Rentrop grade 1-2-3 were accepted as presence of CCV development (group 2). RESULTS: The median of MPV was 9.1±1.4fl. Mean age was 60±12 year. Group 1 consisted of 233 (55.9%) patients and Group 2 consisted of 184 (44.1%) patients. Presence of CCV was significantly associated with high levels of MPV (p=0.005). Presence of CCV was also associated with presence of diabetes and systolic blood pressure. CONCLUSION: High MPV on admission was associated with presence of CCV in patients with ACS.
