Objectives:We aimed to determine the association between Galectin-3 (Gal-3) levels and microvolt T-wave alternans (MTWA) and frequent premature ventricular complexes (PVCs) in single-vessel patients with left ventricular ejection fraction (EF) (LVEF) >35%, who presented with ST-elevated myocardial infarction (MI) (STEMI) and were treated with primary percutane-ous coronary intervention (pPCI).Materials and Methods:A total of 81 patients were included in this cross-sectional study. Blood samples for Gal-3 levels were obtained from all patients at the time of admission. The patients were separated into low and high Gal-3 (≤ and >1.93 ng/dL, respectively) groups. Low-Gal-3 and high-Gal-3 groups were compared with respect to both MTWA and PVC positivity and their association with Gal-3 levels were examined.Results:When compared to the low-Gal-3 group, left atrial volume (LAV) was higher in the high-Gal-3 patients (55.7±18.0 vs 40.6±13.7 mL, p35%.

Introduction: Increased matrix metalloproteinase-9 (MMP-9) levels in ST-elevation myocardial infarction (STEMI) are well established; however, existing data on MMP-9 values as a prognostic marker after STEMI are limited and have been conflicting. Objective: This study aimed to assess the clinical significance of MMP-9 in predicting two-year adverse cardiovascular events in patients who underwent primary percutaneous coronary intervention (PCI) after STEMI. Methods: In this prospective study, 204 patients with STEMI undergoing PCI were included. Participants were classified as high MMP-9 (n=102) or low MMP-9 (n=102) based on a cutoff of 12.92 ng/ml. Both groups were assessed at one and two years after STEMI. Results: Higher cardiovascular mortality at one year was observed in the high MMP-9 group (13.7% vs. 4.9% in the low MMP-9 group, p=0.03). When the follow-up period was extended to two years, the difference in cardiovascular mortality between the groups was more significant (17.6% vs. 4.9%, p=0.004). There was no significant difference at one-year follow-up in rates of advanced heart failure, however at the end of the second year, advanced heart failure was more prevalent in the high MMP-9 group (16.7% vs. 5.9%, p=0.015). After adjustment for potential confounders, a high MMP-9 value had 3.5-fold higher odds for cardiovascular mortality at two-year follow-up than low MMP-9. Conclusion: These results suggest that high MMP-9 levels are a strong predictor of cardiovascular mortality and advanced heart failure at two-year follow-up in STEMI patients. Resumo: Introdução: A elevação das metaloproteinases de matriz 9 (MPM-9) no enfarte do miocárdio com supradesnivelamento do segmento ST (EAMCSST) está bem estabelecida; no entanto, os dados existentes relativos aos valores de MPM-9 como marcadores de prognóstico após o EAMCSST são limitados e contraditórios. Objetivo: Avaliar o significado prognóstico das MPM-9 em eventos cardiovasculares a dois anos nos doentes submetidos a intervenção coronária percutânea primária (ICP) após EAMCSST. Métodos: Neste estudo prospetivo, foram incluídos 204 doentes com EAMCSST submetidos a ICP. Os participantes foram agrupados no grupo de MPM-9 elevadas (n=102) ou no grupo de MPM-9 baixas (n=102) com base no valor MPM-9 de 12,92 ng/ml. Ambos os grupos foram avaliados a um e a dois anos após EAMCSST. Resultados: A mortalidade cardiovascular mais elevada a um ano foi observada no grupo de MPM-9 elevadas (13,7% versus 4,9% no grupo com valores baixos, p=0,03). Quando o período de seguimento foi prolongado a dois anos, a diferença na mortalidade cardiovascular foi ainda superior (17,6% versus 4,9%, p=0,004). Não houve diferenças significativas no seguimento a um ano relativamente à insuficiência cardíaca avançada, mas no fim do segundo ano a insuficiência cardíaca avançada foi superior no grupo com MPM-9 elevadas (16,7% versus 5,9%, p=0,015). Após o ajuste para potenciais fatores confundentes, a presença de MPM-9 elevada aumentou 3,5 vezes a probabilidade de mortalidade cardiovascular no segundo ano de seguimento. Conclusão: Níveis elevados de MPM-9 constituem um importante fator preditor da mortalidade cardiovascular e da insuficiência cardíaca avançada num período de dois anos após EAMCSST.

Introduction Obstructive sleep apnea (OSA) and endothelial dysfunction are associated with cardiovascular risk factors and the development of atherosclerosis. Endocan is a marker of endothelial dysfunction, while obstructive sleep apnea is one of the causes of endothelial dysfunction. In this study, we investigated the relationship between endocan and obstructive sleep apnea severity. Material and methods A total of 179 patients with snoring complaints were included. All patients underwent polysomnography, and based on the results, the participations were allocated to the control group (n = 39) or to the obstructive sleep apnea group (n = 140). The OSA group was classified as having mild (apnea-hypopnea index (AHI) = 5–15; n = 43), moderate (AHI = 15–30; n = 42), or severe OSA (AHI > 30; n = 55). All participations had their endocan levels measured. Results Endocan levels in OSA patients were significantly higher than in the control group (11.8 (3.13–200) vs 3.13 (3.13–23) ng/ml, p < 0.001). Also, endocan levels were significantly higher in the severe OSA group than moderate and mild obstructive OSA (13.2 (3.13–200), 12.6 (3.13–200) and 8.44 (3.13–50.5) ng/ml, p = 0.015, respectively). Multiple logistic regression analysis showed that smoking, age and endocan levels were independent predictors of OSA severity (p = 0.024, p = 0.037, p = 0.004, respectively). Conclusions Endocan seems to be a potential risk stratification marker in this patient population.

Objective: Although neurotensin is found throughout the body including cardiovascular structures, the correlation of plasma neurotensin levels with resistant hypertension (RH) has never been examined. Therefore, we aimed to compare plasma neurotensin concentration, between patients with RH and those with controlled hypertension (CH).Methods: Forty-one patients with RH and 45 patients with CH who had undergone outpatient ambulatory blood pressure measurements were prospectively recruited. RH was defined as uncontrolled blood pressure despite using three antihypertensive agents including a diuretic or need of four or more drugs to control blood pressure. The demographic properties, medications, laboratory parameters including neurotensin levels, and echocardiographic parameters were recorded.Results: There was no significant difference among groups in terms of age, sex, smoking or body mass index. Office and ambulatory blood pressures and mean number of antihypertensive drugs used were significantly higher in patients with RH compared to patients with CH. Plasma neurotensin levels were significantly lower in patients with RH (median: 0.380 ng/ml; interquartile range: 0.292-0.471) than in the patients with controlled blood pressure (median: 0.638 ng/ml; interquartile range: 0.483-0.783). Multivariate and receiver-operating characteristics curve analyses showed that neurotensin is an independent predictor for RH and the optimal cut-off value of neurotensin for RH was lower than 0.509 ng/ml, with a sensitivity of 85.4% and a specificity of 73.3% (area under the curve = 0.793, 95% CI: 0.691-0.894, p < .001)Conclusion: This study is the first to show a correlation between lower neurotensin levels and RH.

BACKGROUND: Although it has been shown that high mean platelet volume (MPV) is associated with target organ damage in hypertensive patients, the relationship between MPV and the development of long-term major adverse cardiovascular events (MACE) has not been thoroughly investigated. In this study, we investigated the relationship between MPV and long-term MACE in hypertensive patients. METHODS: From September 2011 to July 2017, 1507 patients with hypertension were included in this study. Ambulatory blood pressure monitoring was performed in all patients. Patients with chronic renal failure, cardiovascular disease, chronic systemic disease and white coat hypertension were excluded from the study. MACE were defined as myocardial infarction, stroke and cardiovascular mortality. Patients were followed-up until january 2020. RESULTS: The mean follow-up duration was 87 (83.3 ± 24.4) months, and 876 patients completed the study. MACE developed in 79 patients, while 797 patients were event-free. In univariate Cox regression analysis, age, diabetes mellitus (DM), MPV, creatinine, 24-hour systolic blood pressure, and non-dipper hypertension were found to be associated with the development of MACE. In multivariate Cox regression analysis, creatinine and 24-hour systolic blood pressure lost significance, and age, DM, non-dipper hypertension and MPV were found to be independent predictors for MACE development (p < 0.001, p < 0.001, p = 0.044, and p = 0.049, respectively). CONCLUSIONS: MPV, age, DM, and non-dipper hypertension were independent predictors of long-term MACE in hypertensive patients.

Nickel allergy was detected in approximately 15% of the population. Despite this rate, very few patients developed symptoms related to nickel allergy after cardiac device insertion. In this case report, pericardial effusion due to nickel allergy that develops after the insertion of Atrial Septal Defect (ASD) device is described. The patient was discharged with ibuprofen. In some cases, dramatic conditions up to the tampon after effusion may develop. These patients responded to high-dose steroid; however, devastating side effects developed. However, more detailed and comprehensive advanced research is needed on this subject.

The aim of this study was to investigate the possible correlation of serum visfatin levels with resistant hypertension (RHT).Patients who had undergone ambulatory blood pressure measurements (ABPM) during the outpatient controls were prospectively recruited. Seventy-one patients with RHT and 94 patients with controlled hypertension (CHT) were included in the study. RHT was defined as 'uncontrolled blood pressure (BP) despite using three antihypertensive agents including a diuretic or need of four or more drugs to control BP'. The demographic properties, medications used, and laboratory parameters including visfatin levels were recorded.In the RHT group, left ventricular mass index was significantly higher compared with the CHT group (108.13±26.86 vs. 89.46±24.09 g/m, P0.01). High-sensitivity C-reactive protein and visfatin levels were significantly higher in the RHT group [4.0 (5.2) vs. 2.3 (3.0) mg/l, P0.01, and 12.87±4.98 vs. 9.46±4.69 ng/ml, P0.01, respectively] compared with the CHT group. In the multivariate linear regression model, visfatin level remained as an independent predictor for office systolic BP [B: 2.07, 95% confidence interval (CI): 1.17-2.98, P0.01]; office diastolic BP (B: 0.71, 95% CI: 0.27-1.16, P0.01); mean 24-h systolic ABPM (B: 1.46, 95% CI: 0.79-2.13, P0.01); and mean 24-h diastolic ABPM (B: 0.88, 95% CI: 0.42-1.34, P0.01) and was also correlated independently with left ventricular mass index (B: 3.13, 95% CI: 2.58-3.99, P0.01).In this cohort of RHT patients diagnosed with ABPM, we have found an independent correlation between higher visfatin levels and the presence of RHT and left ventricular hypertrophy.

Background: Obstructive sleep apnoea syndrome (OSAS) is reported to be associated with hypertension, coronary artery disease, atrial fibrillation, and heart failure. Galectin-3 plays an important role in the regulation of inflammation, development of cardiac fibrosis, and remodelling. A significant relationship between galectin-3 and the total number of coronary plaques and the macrocalcified plaque structures of patients with type 2 diabetes mellitus has been reported. Aim: The aim of this study was to investigate the association between galectin-3 level and coronary plaque burden as well as OSAS severity in patients with OSAS. Methods: A total of 87 consecutive patients with a diagnosis of OSAS and 21 age- and gender-matched control subjects were recruited for the present study. The patients with OSAS were also categorised according to their apnoea hypopnoea index (AHI) as follows: mild (AHI = 5–15), moderate (AHI = 15–30), and severe (AHI > 30). All study subjects underwent coronary computed tomography angiography to detect coronary atherosclerosis. Also, all participants of serum galectin-3 concentrations were measured. Results: Mean galectin-3 level was significantly higher in patients with OSAS compared to control subjects (p < 0.001) and in the severe OSAS group, compared to the moderate and mild OSAS groups (p < 0.001). Correlation analysis indicated significant positive relationships between galectin-3 concentrations and the total number of coronary plaques (p < 0.001), high-sensitivity C-reactive protein (p = 0.001), and severity of OSAS (p < 0.001). In multivariate analysis, galectin-3 (p = 0.01) and age (p = 0.025) were significant independent predictors of coronary atherosclerosis, after adjusting for other risk factors. Also, it has been found that galectin-3 concentration is a predictor of OSAS severity (p = 0.001). Conclusions: Galectin-3 is associated with coronary atherosclerosis and OSAS severity in OSAS patients.

Introduction: Previous studies have demonstrated the predictive value of the neutrophil-to-lymphocyte ratio (NLR) in many cardiovascular disorders. The aim of this study was to assess whether NLR is associated with echocardiographic or electrocardiographic parameters, or with predicted five-year risk of sudden cardiac death (SCD), in patients with hypertrophic cardiomyopathy (HCM). Methods: This prospective observational study included 74 controls and 97 HCM patients. Three years of follow-up results for HCM patients were evaluated. Results: NLR was significantly higher in patients with fragmented QRS, ventricular tachycardia, and presyncope than in those without (p=0.031, 0.030, and 0.020, respectively). NLR was significantly higher in patients whose predicted five-year risk of SCD was more than 6% and whose corrected QT interval was greater than 440 ms (p=0.022 and 0.001, respectively). It was also significantly higher in patients whose left ventricular ejection fraction (LVEF) was 60% (p=0.017). Conclusion: NLR was significantly higher in patients with HCM compared to the control group. A high NLR is associated with a higher five-year risk of SCD in patients with HCM. Resumo: Introdução: Estudos prévios demonstraram o valor preditivo da relação neutrófilos/linfócitos (RNL) em muitas alterações cardiovasculares. O objetivo deste estudo foi avaliar se a RNL está associada a parâmetros ecocardiográficos ou eletrocardiográficos, ou com o score de risco de morte súbita cardíaca (MSC) a cinco anos em doentes com miocardiopatia hipertrófica (MCH). Métodos: Este estudo prospetivo observacional incluiu 74 controlos e 97 doentes com MCH. Foram avaliados os resultados dos doentes com MCH ao longo de três anos de seguimento. Resultados: O valor da RNL foi significativamente superior nos doentes com QRS fragmentado, com taquicardia ventricular e com pré-síncope do que nos que não revelaram esses sinais (valores p: 0,031, 0,030, 0,020, respetivamente). O valor RNL foi estatística e significativamente superior nos doentes com risco de MSC previsível a cinco anos superior a 6%, e com um intervalo QT corrigido superior a 440 ms (valores p: 0,022, 0,001, respetivamente). O valor da RNL foi significativamente superior nos doentes com fração de ejeção (FE) 60% (valor p = 0,017). Conclusão: A RNL foi significativamente superior nos doentes com MCH quando comparada com o grupo controlo. Uma RNL alta está associada a um score de risco de MSC elevado aos cinco anos em doentes com MCH.

The plateletcrit has been investigated as a new predictor of cardiovascular risk. The objective of our study was to investigate the role of admission plateletcrit in predicting long-term cardiovascular mortality in patients presenting with non-ST-segment elevation myocardial infarction (NSTEMI). We enrolled 296 patients with NSTEMI (mean age 59.2 ± 11.8 years; 228 men, 68 women) in this study. The study population was divided into tertiles on the basis of admission plateletcrit values. A high plateletcrit (n = 98) was defined as a value in the upper third tertile (plateletcrit0.23), and a low plateletcrit (n = 198) was defined as any value in the lower two tertiles (plateletcrit ≤0.23). The median follow-up time was 38 months. In multivariate analyses, a significant association was noted between high plateletcrit values and the adjusted risk of long-term mortality (odds ratio = 12.15, 95% confidence interval = 1.78-82.77; P 0.001). In the Kaplan-Meier survival analysis, the long-term mortality rate was 20.4% in the high plateletcrit group versus 4.5% in the low plateletcrit group (P 0.001). Long-term major advanced cardiac events (MACE), hospitalization for heart failure and reinfarction were significantly higher in patients with high plateletcrit. Admission plateletcrit is a strong and independent predictor of long-term cardiovascular mortality in patients with NSTEMI.

Introduction Both end-organ damage and high red cell distribution width (RDW) values are associated with adverse cardiovascular events, inflammatory status, and neurohumoral activation in hypertensive disease and in the general population. In this study, we investigated the relationship between RDW and end-organ damage in hypertensive patients. Material and methods The 446 systo-diastolic hypertensive patients included in the study received 24-hour ambulatory blood pressure monitoring. Left ventricular mass index, glomerular filtration rate, and microalbuminuria were measured to identify end-organ damage. High-sensitivity C-reactive protein (hs-CRP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels of all patients were also examined. Results The mean age of the participants was 49.96 ±11.04 years. The mean RDW was 13.06 ±1.05%. Red cell distribution width was positively correlated with left ventricular myocardial index (LVMI), urinary albumin, hs-CRP, and NT-proBNP (r = 0.298, p < 0.001; r = 0.228, p < 0.001; r = 0.337, p < 0.001; r = 0.277, p < 0.001, respectively), while RDW was negatively correlated with eGFR (r = –0.153, p < 0.001). Additionally, while there was a positive correlation between RDW and 24-h systolic blood pressure, no correlation was found between RDW and 24-h diastolic blood pressure (r = 0.132, p = 0.006 and r = 0.017, p = 0.725, respectively). Multiple linear regression analysis revealed that RDW levels were independently associated with eGFR, LVMI, and severity of albuminuria (β = 0.126, p = 0.010; β = –0.149, p = 0.002; β = 0.114, p = 0.035). Conclusions High RDW levels in systo-diastolic hypertensive patients were found to be an independent predictor of end-organ damage.

Objective Micro T-wave alternans (MTWA) has been associated with poor arrhythmic prognosis in various cardiac disorders. The aim of this study was to assess the relationship between the presence of MTWA and the predicted 5-year risk of sudden cardiac death (HCM Risk-SCD) among patients with hypertrophic cardiomyopathy (HCM). Methods A total of 117 consecutive HCM patients were included in this prospective observational study. Patients were divided into two groups, according to the presence [MTWA (+) group (n=44)] or absence [MTWA (-) group (n=73)] of MTWA on ambulatory (Holter) electrocardiography. Results The risk of HCM Risk-SCD (%), the rate of high-risk patients (HCM Risk-ECG >6%), the requirement for cardiopulmonary resuscitation, and implanted cardioverter defibrillator therapy, the percentage of some clinical, echocardiographic, and Holter findings were all statistically higher in the MTWA (+) group than in the MTWA (-) group (all p 4.9% was identified as an effective cutoff point in the MTWA (+) for HCM. The HCM Risk-SCD value of more than 4.9 yielded a sensitivity of 93.2% and a specificity of 84.5%. Conclusion The presence of the MTWA on ambulatory electrocardiogram seems to be significantly associated with increasing percentages of the predicted HCM Risk-SCD score in patients with HCM. The MTWA was determined as an independent high-risk indicator for HCM Risk-SCD.

The prognostic value of pentraxin 3 (PTX3) has been documented in patients with acute coronary syndrome. However, its long-term prognostic value in acute ST-segment elevation myocardial infarction (STEMI) remains unclear. The aim of this study was to evaluate the prognostic value of PTX3 in patients with STEMI undergoing a primary percutaneous coronary intervention (PCI).We prospectively enrolled 499 consecutive STEMI patients undergoing primary PCI. The high-PTX3 group (n=141) was defined as having values in the third tertile (≥3.2 ng/ml) and the low-PTX3 group (n=358) included patients with values in the lower two tertiles (3.2 ng/ml).The patients in the high-PTX3 group were older (mean age 54.3±11.8 vs. 58.5±13.1 years, P=0.002). Higher in-hospital cardiovascular mortality and 2-year all-cause mortality rates were observed in the high-PTX3 group (9.9 vs. 2.8%, respectively, P0.001; 21 vs. 6.2%, respectively, P0.001). In a Cox multivariate analysis, a high admission PTX3 value (3.2 ng/ml) was found to be an independent predictor of 2-year all-cause mortality (odds ratio: 2.3, 95% confidence interval: 1.20-4.90, P=0.025).These results suggest that a high admission PTX3 level was associated with increased in-hospital cardiovascular mortality and 2-year all-cause mortality in patients with STEMI undergoing primary PCI.

Objective: Rheumatic carditis-induced mitral valve disease is associated with a chronic inflammatory process. The close relationship between inflammation and prothrombotic processes is known. Our goal was to examine the relationship between the presence of left atrial (LA) thrombus in patients with rheumatic mitral valve stenosis (RMVS) and platelet-to-lymphocyte ratio (PLR), which is an inflammatory marker. Methods: This cross-sectional study included 351 consecutive patients diagnosed with RMVS upon presentation to the cardiology polyclinic. All patients were evaluated using transthoracic and transesophageal echocardiography and were divided into 2 groups: those with and without LA thrombus. In addition to echocardiographic and biochemical parameters, PLR was compared between the groups. Student’s t-test, Mann–Whitney U test, logistic regression analysis, and receiver operating characteristic (ROC) curve analysis were used for statistical analysis. Results: No significant differences in terms of age, gender, body mass index, and comorbidities were found between the groups with and without LA thrombus. In the group with LA thrombus, higher red cell distribution width, mean platelet volume, and platelet count and lower lymphocyte count were detected. In addition, C-reactive protein levels were significantly higher in the LA thrombus group (4.7 vs. 2.7 mg/L, p

Abstract. Background: The aim of this study was to assess the periprocedural and one-year outcomes of two different cerebral protection systems used during carotid artery stenting (CAS). Patients and methods: We enrolled 90 consecutive patients with carotid artery stenosis who underwent CAS with a proximal flow blockage protection system (mean age 69.7 ± 8) or distal protection with a filter (mean age 70.8 ± 7). Results: CAS was performed successively on 89 patients (99 %). Adverse events were defined as major stroke, minor stroke, transient ischemic attack (TIA), myocardial infarction, and death. Two strokes, one TIA, one death, and one myocardial infarction were observed in-hospital. There were no significant differences in safety or benefits between the proximal flow blockage embolic protection system (n = 45) and the distal filter protection system (n = 45) in terms of clinically apparent cerebral embolism, TIA, death, or myocardial infarction during the periprocedural stage or during the one-year follow-up period. Conclusions: Although it has been shown that the proximal flow blockage cerebral protection system decreases the risk of silent cerebral embolism, it has no advantage over the distal filter protection system in terms of adverse cerebrovascular or cardiac events during the periprocedural stage or during the long-term follow-up period.

Introduction: Nowadays, clopidogrel and acetylsalicylic acid (ASA) have become routinely applied therapies in percutaneous coronary interventions (PCI) with stenting. Aim: Numerous variables can interfere with antiplatelet responsiveness, so we aimed to investigate the role of different variables associated with ASA or clopidogrel resistance in stable coronary artery disease. Material and methods: A total of 207 patients undergoing elective PCI were included in the analysis. All patients received a loading dose of clopidogrel and ASA during PCI procedure and followed by dual antiplatelet therapy. Clopidogrel and ASA resistance were measured by impedance aggregometry method. Results: Of the patients, 19.8% had clopidogrel resistance, 18.8% had ASA resistance, 9.2% had both clopidogrel and ASA resistance, and 71.5% were responsive to both drugs. In multivariate analysis, platelet count, angiotensin receptor blocker (ARB) use, and ASA resistance were independent variables associated with clopidogrel resistance, and clopidogrel resistance was the only variable associated with ASA resistance. In differentiating whether clopidogrel resistance exists or not, optimum ASA aggregometry response cut-off values were specified, and in differentiating whether ASA resistance exists or not, optimum clopidogrel aggregometry response cut-off values were specified. Conclusions: In this study, there was a higher incidence of low responsiveness to ASA when there was a low response to clopidogrel, and vice versa. Angiotensin receptor blocker use, platelet count, and ASA resistance were independent variables associated with clopidogrel resistance. Clopidogrel resistance was the only independent variable associated with ASA resistance. Angiotensin receptor blocker use seems to an independent risk factor for clopidogrel resistance in this study, but this result needs to be verified in other studies.

Objective The aim of this cross-sectional study was to evaluate microvolt T-wave alternans (MTWA) as a marker of myocardial electrical instability in normotensive and hypertensive individuals with either nondipper or dipper-type circadian rhythm of blood pressure. Materials and methods The study group included a total of 181 patients: 118 hypertensive patients and 63 normotensive healthy volunteers [mean age 46 ± 8; 34 men (54%)]. The patients with hypertension were divided into two groups on the basis of their results of 24-h ambulatory blood pressure monitoring: 61 patients with dipper hypertension [mean age 46 ± 6; 32 men (52.5%)] and 57 patients with nondipper hypertension [mean age 48 ± 10; 36 men (63.2%)]. The MTWAs of all patients were analyzed using the time-domain modified moving average method by means of a treadmill exercise stress test. Results MTWA positivity was statistically significantly different between all groups. Left ventricular mass index, E/E', interventricular septum, posterior wall, 24-h systolic blood pressure and diastolic blood pressure, and night-time systolic blood pressure and diastolic blood pressure were correlated positively with MTWA. Left ventricular mass index and the presence of nondipper hypertension were determined to be independent predictors of MTWA positivity. Conclusion The blunting of the nocturnal decrease in blood pressure was associated with MTWA positivity in hypertensive patients.

Objective: The aim of this study was to assess subclinical left (LV) and right ventricular (RV) dysfunction novel load-independent isovolumic myocardial acceleration (IVA) derived from tissue Doppler imaging (TDI) in patient with metabolic syndrome (MetS). Methods: This study had an observational case-control design. The study included 133 subjects which were divided into two groups: 75 patients with MetS and 58 controls without MetS. MetS was defined by the presence of ≥3 criteria according to ATP-NCEP III guidelines. All the subjects underwent laboratory blood tests and complete conventional echocardiography and TDI. Student’s t, Mann-Whitney U, Pearson’s, and multiple regression analysis were used for statistical analysis. Results: There were no significant difference between two groups in terms of traditional echocardiographic parameters. The diastolic and global functions of both ventricles were significantly impaired in MetS group. The TDI-derived IVA of the LV and the RV was significantly lower in patients with MetS (3.2±0.9 vs. 4.0±1.4, p

Mitral stenosis is the most common valvular pathology complicating pregnancy. Herein are reported the details of a 26-week pregnant patient with severe mitral stenosis and NYHA class 3-4 symptoms.

Objective: It has been shown that the presence of fragmented QRS (fQRS) is associated with poor prognosis in many cardiovascular diseases and in patients with hypertrophic cardiomyopathy (HCM). However, no study has shown an association with the absolute risk score of sudden cardiac death. The aim of this study was to determine the relationship between QRS and the predicted risk score of sudden cardiac death at 5 years (HCM Risk-SCD) in HCM patients. Methods: In total, 115 consecutive HCM patients were included in this prospective observational study. The patients were divided into two groups according to the presence [fQRS(+) group (n= 65)] or absence [fQRS(-) group (n= 50)] of fQRS on a 12-lead electrocardiogram (ECG). Results: The HCM Risk-SCD (%) HCM Risk-SCD (>6%) values and some echocardiographic parameters, including ventricular extrasystole, ventricular tachycardia, cardiopulmonary resuscitation, implantable cardioverter defibrillator implantation, appropriate shock, and heart failure at the time of admission, were significantly higher in the fQRS(+) group than in the fQRS(-) group (all p4 was identified as an effective cut-off point in fQRS for HCM. An HCM Risk-SCD value of >4 yielded a sensitivity of 77% and a specificity of 76%. Conclusion: fQRS is determined to be an independent high-risk indicator of HCM Risk-SCD. It seems to be associated with increased ventricular arrhythmias and some echocardiographic parameters.

Background: Although it has declined in developed countries, mitral valve stenosis is problematic in developing countries; its main cause is rheumatic fever. In patients with rheumatic mitral stenosis (RMS), ongoing chronic inflammation may resultin the progression of valvular damage and the formation of spontaneous echocardiographic contrast (SEC). Aim: We investigated the role of the neutrophil/lymphocyte ratio (NLR) as an indicator of ongoing inflammation and independentpredictive risk factor for SEC in RMS patients. Methods: A total of 112 patients (mean age 46 ± 10.6; 73.2% female) with RMS who underwent both transthoracic echocardiography and transoesophageal echocardiography were enrolled; the control group comprised 100 healthy volunteers (mean age 44 ± 9.1; 62% female). Patients were divided into two subgroups according to the formation of SEC in the left atrium and appendage. Haematological and biochemical indices were measured in all patients and controls. Result: NLR was higher in the patients than controls (2.6 ± 1.15 vs. 1.71 ± 0.53, p < 0.001). In addition, it was higher in the SEC-positive group (mean age 47 ± 10.3; 68.4% female) compared to the SEC-negative group (mean age 44 ± 10.7; 78.2% female; 3.21 ± 1.25 vs. 1.97 ± 0.55, p < 0.001). In multivariate analysis, NLR (odds ratio [OR] 20.602, 95% confidence interval [CI] 4.678–90.731; p < 0.001) and left atrial diameter (OR 5.966, 95% CI 2.166–16.429; p = 0.01) were found tobe independent predictors of SEC in RMS patients. Conclusions: RMS patients exhibit on-going inflammation; NLR is a good marker of this. The formation of SEC is associated with inflammation and NLR is an independent predictive risk factor for SEC.

Background: Isolated systolic hypertension (ISHT) is a subtype of hypertension (HT) that often exhibits wide pulse pressure, and pulse pressure has a strong predictive value for future adverse cardiovascular events. Previous studies have shown the effects of leukocyte count on the prognosis of ischaemic heart disease and HT. Aim: Thus, in this cross-sectional study, we analysed the relationship between leukocyte counts and subtypes in HT and non-HT groups. Methods: The study population consisted of 960 consecutive patients who were admitted to the outpatient clinic of our hospital. After ambulatory blood pressure values were assessed, the participants were divided into three groups: ISHT (n = 98), systo-diastolic hypertensives (SDHT, n = 405), and non-hypertensives (non-HT, n = 457). Results: The subjects in the ISHT group were older than those in the SDHT and non-HT groups (64 ± 10, 53 ± 12, and 52 ± 13, respectively; p < 0.001). The leukocyte and neutrophil counts and neutrophil/lymphocyte (NL) ratios were significantly different in all groups. In subgroup analysis, the leukocyte count, neutrophil count, and N/L ratio were higher in the ISHT and SDHT groups than in the non-HT group (p < 0.001 for all). The leukocyte count, neutrophil count, and N/L ratio were significantly higher in the ISHT group than in the SDHT group (p = 0.023, p = 0.007, p = 0.010, respectively). Neutrophil count (p = 0.012; OR = 1.229, 95% CI 1.046–1.444) was an independent risk factor for ISHT in multivariate logistic regression analysis . Conclusions: The leukocyte and neutrophil counts and N/L ratios were higher in the ISHT group than in the SDHT and non-HT groups. High neutrophil count was an independent predictor of ISHT.

Objectives Fragmented QRS (fQRS) has been found to be associated with high mortality and arrhythmic events in acute coronary syndromes. Regional systolic function using wall motion score index (WMSI) is an alternative to left ventricular ejection fraction (LVEF) for the assessment of left ventricular systolic function. The aim of this study was to investigate the relation between the presence of fQRS on admission electrocardiogram (ECG) and WMSI in ST elevation myocardial infarction (STEMI) underwent primary coronary intervention (PCI). The in-hospital and long-term prognostic significance of persistent fQRS was also evaluated. Methods In this retrospective study, 542 patients with a diagnose of STEMI underwent primary PCI were included. Study patients were divided into two groups according to the presence (n = 153) or absence (n = 389) of a fQRS on admission ECG. Results WMSI was found to be significantly higher in fQRS(+) group compared to the fQRS(–) group (P

Objectives The aim of this study was to evaluate the prognostic value of fragmented QRS (fQRS) on electrocardiography (ECG) patients with acute ST-segment elevation in myocardial infarction (STEMI), who are undergoing primary percutaneous coronary intervention (PCI). Methods We prospectively enrolled 414 consecutive STEMI patients (mean age of 55.2 ± 12.2 years old, range of 26–91-years old) undergoing primary PCI. The study patients were divided into two groups according to the presence or absence of fQRS as shown by ECG in the first 48 hours. The presence of fQRS group was defined as fQRS(+) (n = 91), and the absence of fQRS group was defined as the fQRS(–) (n = 323) group. Clinical characteristics and the one-year outcome of the primary PCI were analyzed. Results The patients in the fQRS(+) group were older (mean age 60.7 ± 12.5 vs. 53.6 ± 11.6 years old, P

Left ventricular (LV) hypertrophy (LVH) predicts increased mortality in part due to an elevated incidence of sudden cardiac death in hypertension. The aim of the present study was to investigate the relation of microvolt T-wave alternans (MTWA) with different LV geometric patterns in patient with sustained hypertension.This study consisted of 311 consecutive patients with sustained hypertension who were divided into four groups according to LV geometrical patterns. 90 patients were in the normal geometry group (NGG) [mean age 49.6 ± 7.8 years; 60 males (66.7%)], 99 patients were in the concentric remodeling group (CRG) [mean age 50.9 ± 6.6 years; 50 males (50.6%)], 63 patients were in the concentric hypertrophy group (CHG) [mean age 51.6 ± 7.3 years; 32 males (50.7%)] and 58 patients were in the eccentric hypertrophy group (EHG) [mean age 51.6 ± 9.0 years; 30 males (51.7%)]. Physical examination, laboratory work-up, office blood pressure measurement, transthoracic echocardiography and MTWA measurements were performed on all participants.MTWA positivity was significantly higher in EHG and CHG as compared to CRG and NGG (p0.001). Left ventricle mass index (LVMI), LV end-diastolic diameter (LVEDD), LV end-systolic diameter (LVESD), interventricular septum diameter (IVSd), posterior wall diameter (PWd) and office systolic blood pressure (SBP) were found to be significantly positively correlated with MTWA (all p-values0.05).We demonstrated that increased LVMI is associated with an elevated MTWA positivity in sustained hypertensives. Moreover, clinically significant LV geometric patterns including both concentric and eccentric hypertrophy are related with a raised MTWA positivity, which may lead to particular predilection to life-threatening ventricular arrhythmias and sudden cardiac death in sustained hypertension.

Objectives: To evaluate subclinical left ventricular and right ventricular systolic impairment in dipper and non-dipper hypertensives by using isovolumic acceleration.About 45 normotensive healthy volunteers (20 men, mean age 43 ± 9 years), 45 dipper (27 men, mean age 45 ± 9 years) and 45 non-dipper (25 men, 47 ± 7 years) hypertensives were enrolled. Isovolumic acceleration was measured by dividing the peak myocardial isovolumic contraction velocity by isovolumic acceleration time.Non-dippers indicated lower left ventricular (2.2 ± 0.4 m/s(2) versus 2.8 ± 1.0 m/s(2), p 0.01) and right ventricular isovolumic acceleration values (2.8 ± 0.8 m/s(2) versus 3.5 ± 1.0 m/s(2), p = 0.012) compared with dippers. Left ventricular mass index (p = 0.001), interventricular septal thickness (p = 0.002) and myocardial performance index (p 0.001) were negatively correlated with left ventricular isovolumic acceleration. Left ventricular septal thickness (p = 0.002), mass index (p = 0.001) and right ventricular myocardial performance index (p 0.001) were negatively correlated with right ventricular isovolumic acceleration.The present study demonstrates that non-dipper hypertensives have increased left and right ventricular subclinical systolic dysfunction compared with dippers. Isovolumic acceleration is the only echocardiographic parameter in predicting this subtle impairment.

BACKGROUND Elevated mean platelet volume may reflect presence of active large platelets, which lead to fatal or non-fatal cardiovascular events. In recent studies, lack of nocturnal blood pressure fall was presented as an independent predictor of poor prognosis in essential hypertension. The relation of raised MPV with left ventricular hypertrophy has also been reported in hypertension. The aim of this study was to investigate the relation between MPV, non-dipping blood pressure pattern, and left ventricular mass index (LVMI) in sustained hypertension. MATERIAL AND METHODS A total of 2500 patients, whose ambulatory blood pressure (ABP) records had been evaluated retrospectively between January 2010 and December 2012, were included. Patients were divided into 3 groups according to their ABP values: non-dipper hypertensive (n=289), dipper hypertensive (n=255), and normotensive (n=306). The MPV levels and biochemical analyses were recorded from patient files and, LVMI were automatically calculated using a regression equation. RESULTS The non-dipper and dipper hypertensive groups had significantly higher MPV levels than normotensives (8.4±1 fL, 8.3±1 fL, and 8.1±0.6 fL, respectively, p

Introduction: Many studies have reported the diagnostic and prognostic value of haemoglobin A1c (HbA1c) levels in patients with acute coronary syndrome. However, the short- and long-term prognostic value of HbA 1c level in patients with ST elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI) is controversial. Aim: To investigate whether admission HbA 1c level has a prognostic value for in-hospital, short-, and long-term cardiovascular (CV) mortality and major adverse cardiovascular events in patients with STEMI undergoing primary PCI. Material and methods: This prospective study included 443 consecutive patients with STEMI who underwent primary PCI between September 2010 and July 2012. The patients were divided into three groups based on admission HbA1c levels: group I (HbA 1c ≤ 5.6%), group II (HbA 1c 5.7–6.4%), and group III (HbA 1c ≥ 6.5%). The in-hospital, 1-month, and 1-year CV events of all 3 patient groups were followed up. Results: A significant association was found between HbA 1c level and 1-year primary clinical outcomes, including CV mortality, non-fatal reinfarction, and stroke (p = 0.037). In addition, age, Killip class > 1, and left ventricular ejection fraction were found to be independent predictors of long-term CV mortality in multivariate analysis (hazard ratios (95% confidence interval) 1.081 (1.020– 1.146), 4.182 (1.171–14.935), and 0.832 (0.752–0.920); p = 0.009, p = 0.028, and p < 0.001, respectively). Conclusions: In this study, we demonstrated that increased admission HbA 1c levels were associated with higher rates of major adverse CV events, including mortality, non-fatal reinfarction, and stroke, in patients with STEMI who underwent primary PCI.

QT dispersion (QTd) was shown to be an independent predictor of mortality in hemodialysis (HD) patients. It may be hypothesized that coronary artery calcification is related to QTd in HD patients because widespread calcification may also involve the cardiac conducting system in these patients. In this study, we aimed to investigate the relationships of corrected QTd (QTcd) with coronary artery calcification score (CACS), carotid plaque score (CPS) and possible influence of these parameters on survival of HD patients.Seventy-two HD patients (33 male, 39 female) were enrolled into the study. Mean age of the patients was 44 ± 12 years. Mean follow-up duration was 77 ± 24 months. CACS was determined by computed tomography. QTcd values were calculated as the difference of maximum and minimum QT intervals. Left ventricular mass index (LVMI) and CPS were measured by echocardiography.QTcd was significantly correlated with CACS (r = 0.233, p = 0.049), CPS (r = 0.354, p = 0.003) and LVMI (p = 0.011, r = 0.299). CPS was found to be significantly higher in the group with high QTcd (60 ms) [2 (1-4) versus 0 (0-1), p = 0.02]. CACS was significantly correlated with age (r = 0.44, p0.001), LVMI (r = 0.52, p0.001) and CPS (r = 0.32, p = 0.003). In Kaplan-Meier analysis, survival of patients with high QTcd was significantly lower than the patients with low QTcd. In Cox regression analysis for predicting mortality, age, serum albumin and QTcd were found to be the independent predictors of mortality.QTcd independently predicted mortality, and it was significantly associated with coronary artery calcification, left ventricular hypertrophy and atherosclerosis in HD patients.

Rheumatic mitral valve stenosis (RMVS)-induced left atrial thrombus (LAT) and embolic complications may have clinically devastating consequences. Stasis in the left atrium induced by valvular obstruction is a major factor in the development of thrombus. However, the development of thrombus may not be solely associated with stasis, as it is known that the inflammatory process increases the tendency for thrombosis. The study aim was to examine the relationship between the neutrophil-to-lymphocyte ratio (NLR), an indicator of inflammation, and the existence of LAT.A total of 313 consecutive patients with RMVS and mitral valve area (MVA)2 cm2 was included in this cross-sectional study. Patients were allocated to two groups with or without LAT using transthoracic and transesophageal echocardiography. Routine biochemical analyses and electrocardiographic examinations were also carried out. The NLR was calculated utilizing blood count analysis.The presence of LAT was identified in 78 RMVS patients (24.9%). No significant differences in terms of age, gender, body mass index were found between the groups with and without LAT. On echocardiographic examination, a higher mean gradient and left atrial diameter, as well as a smaller MVA, were determined in patients with LAT (p0.001). In those patients with LAT, higher C-reactive protein levels and higher leukocyte and neutrophil counts (p0.001) and lower lymphocyte counts were noted (p = 0.001). The NLR was shown to be higher in patients with LAT (p0.001). Multivariate regression analysis showed that the relationship between LAT and a high NLR continued independently (OR 5.3; 95% CI 2.9-9.4; p0.001).The NLR is an easily obtained, low-cost and easily repeated parameter that seems effective for identifying RMVS patients who are at high risk of developing LAT.

Slow coronary artery flow (SCF) is characterized by angiographically confirmed delayed vessel opacification in the absence of any evidence of obstructive epicardial coronary artery disease. Microvolt T-wave alternans (MTWA) is defined as beat-to-beat changes in shape, amplitude, or timing of ST segments and T waves, and is utilized in predicting sudden cardiac death and life-threatening malign ventricular arrhythmias in high-risk patients. In our study, we aimed to evaluate the effects of slow coronary artery flow on MTWA.Thirty-nine consecutive patients (SCF group: 6 women and 33 men; mean age, 49 ± 10 years) with angiographally documented SCF in at least 1 major epicardial artery and 39 patients (control group: 13 women and 26 men; mean age, 50 ± 10 years) with normal coronary arteries were included in the study. Coronary flow rates of all patients were calculated by thrombolysis in myocardial infarction frame count (TFC). The MTWAs of all patients were analyzed using the time-domain modified moving average method by means of a treadmill exercise stress test.The age distribution , body mass index, and diastolic and systolic blood pressure (BP) were similar in the SCF and control group. In the SCF group, the three epicardial coronary artery corrected TFCs and mean TFCs were significantly higher than in the control group (for all, p0.001). MTWA positivity in the SCF group was statistically significant compared to the control group (p = 0.006). Spearman's correlation analysis, showed a positive correlation between MTWA and right coronary artery (RCA) TFC and mean TFC (r = 0.368, p = 0.001 and r = 0.271, p = 0.016, respectively). In linear regression analysis, only the right coronary artery TFC was correlated with positive MTWA (p = 0.001).The results of our study suggest that diagnosed SCF is associated with MTWA positivity. Furthermore, we determined that only RCA TFC was predictive of positive MTWA.Microvolt T-wave alternans; Slow coronary flow.

Uric acid (UA) is an independent risk factor for the development of coronary heart disease. Serum UA levels have been correlated with all major forms of death from cardiovascular disease, including acute, subacute, and chronic forms of coronary artery disease (CAD), heart failure, and stroke. However, its value in acute ST-segment elevation myocardial infarction (STEMI) remains unclear. The aim of this study was to evaluate the prognostic value of UA in patients with STEMI undergoing primary percutaneous coronary intervention (PCI).We prospectively enrolled 434 consecutive Turkish STEMI patients (mean age 55.4 ± 12.4 years, 341 male, 93 female) undergoing primary PCI. The study population was divided into tertiles based on admission UA values. The high UA group (n = 143) was defined as a value in the third tertile (5.7 mg/dl), and the low UA group (n = 291) included those patients with a value in the lower two tertiles (≤ 5.7 mg/dl). Clinical characteristics, in-hospital and six-month outcomes of primary PCI were analyzed.Compared to the low UA group, only Killip class1 at admission was more prevalent in the high UA group (3.4% vs. 17.5%, p0.001, respectively). Higher in-hospital cardiovascular mortality and six-month all-cause mortality rates were observed in the high UA group than in the lower group (12.6% vs. 1.7%, respectively, p0.001) and (19.6% vs. 4.1%, respectively, p0.001). In Cox multivariate analysis; a high admission UA value (5.7 mg/dl) was found to be a powerful independent predictor of six-month all-cause mortality (hazard ratio: 5.57, 95% confidence interval: 1.903-16.3, p = 0.002).These results suggest that a high level of UA on admission was associated with increased in-hospital cardiovascular mortality, and six-month all-cause mortality in Turkish patients with STEMI undergoing primary PCI.Primary angioplasty; ST elevation myocardial infarction; Uric acid.

OBJECTIVES Galectin-3 is a marker associated with myocardial fibrosis and left ventricular myocardial index (LVMI). Myocardial fibrosis and LVMI have been reported in many studies to be associated with microvolt T-wave alternans (MTWA) positivity. In this study, galectin-3 levels of normotensive individuals and sustained systolic-diastolic hypertensive patients were compared and the association between galectin-3 levels and ambulatory ECG-based MTWA was investigated. METHODS A total of 184 individuals were included in the study, among whom, 43 were normotensive and 141 had sustained systolic-diastolic hypertension without cardiovascular or chronic renal failure. Galectin-3, MTWA, and LVMI were evaluated in all participants. Galectin-3 levels of hypertensive and normotensive participants were compared. The association between galectin-3, MTWA, LVMI, and estimated glomerular filtration rate (eGFR) was investigated in hypertensive patients. RESULTS LVMI and galectin-3 levels were higher among hypertensive patients compared with normotensives (94.9±26.8 vs. 76.4±22.9 g/m, 7.325±2.123 vs. 5.233±1.506 ng/ml; P

Pulse pressure (PP) has been reported as an independent predictor of cardiovascular mortality in hemodialysis patients. In this study, we aimed to investigate association of PP with echocardiographic and vascular structural changes such as atherosclerosis and arterial calcifications in HD patients. In this cross-sectional study, 108 chronic hemodialysis patients (49 male, 59 female, mean age: 46 ± 13 years) were included. Biochemical analyses, echocardiographic and high-resolution carotid Doppler examinations were done. Aortic wall and coronary artery calcifications were measured with electron beam computed tomography. The degree of carotid artery stenosis was measured at four different sites (communis, bulbus, interna and externa) in both carotid arteries. PP was strongly correlated with systolic (r: 0.82) and diastolic (r: 0.33) blood pressure, left ventricular mass index (r: 0.58), left ventricle end diastolic diameter (r: 0.38) and weakly correlated with aortic wall calcification score (r: 0.26) and carotid plaque score (r: 0.27), but not with coronary artery calcification score. Patients with carotid plaque had higher PP than patients without plaque (50 ± 16 mmHg versus 44 ± 14 mmHg, P = 0.05). Patients were divided into three groups according to aortic wall calcification score. PP was significantly higher in patients with higher aortic wall calcification (54 ± 16 mmHg) than patients with lower aortic wall calcification (44 ± 15 mmHg, P = 0.04). However, on multivariate linear regression analysis for predicting PP, the only significant factor retained was left ventricle end diastolic diameter. PP was weakly associated with large vessel calcification and atherosclerosis in hemodialysis patients. The bulk of the effect on PP seems to be due to hypervolemia.

Mitral valve stenosis is a common manifestation of chronic rheumatic heart disease. In rheumatic mitral valve stenosis (RMVS) patients, left atrial spontaneous echo contrast (LASEC) is an independent predictor of thromboembolism risk. While the anticoagulant therapy algorithm for atrial fibrillation patients is clear, the clinical tools determining high-risk patients in sinus rhythm are insufficient. Our aim is to examine the relationship between CHA2DS2-VASc score in RMVS patients in sinus rhythm and the presence of LASEC. The patients with RMVS upon presentation to the cardiology polyclinic were included in this cross-sectional study consecutively, and CHA2DS2-VASc scores were calculated. All patients were evaluated with transthoracic and transesophageal echocardiography and were divided into two groups as those with and without LASEC. The total number of patients was 265, with LASEC determined in 97 (36.6 %) and not determined in 168 (63.4 %). No significant differences in terms of age, gender, and body mass index were found between the groups. Patients with LASEC had higher mean CHA2DS2-VASc score than patients without LASEC (2.10 ± 1.21 vs. 1.11 ± 0.7, respectively; p

Background: Metabolic syndrome (MetS) is found to be associated with deterioration of the left ventricular (LV) systolic and diastolic functions. One of the factors for this impairment is myocardial fibrosis. Fragmented QRS (fQRS) complexes are found to be associated with myocardial fibrosis. The aim of the study was to evaluate if the presence of fQRS on electrocardiogram (ECG) can detect pronounced impairment in the LV systolic and diastolic functions in MetS patients. Methods: The study included 111 (mean age 47 ± 9, 49.5% male) MetS patients and 96 (mean age 45 ± 9, 58.3% male) control subjects without MetS. ECG was evaluated for the presence of fQRS. Each patient underwent conventional echocardiography and tissue Doppler imaging. Results: Fragmented QRS was more common among MetS patients (26.1% vs. 14.6%, p = 0.041). MetS was associated with subclinical LV systolic and LV diastolic dysfunctions. In subgroup analyses of MetS patients, the presence of fQRS on ECG had a higher E/E’ ratio and lower E’ velocity, indicating pronounced diastolic dysfunction, as well as lower isovolumic acceleration (IVA), indicating profound subclinical LV systolic dysfunction. E/E’ ratio and IVA were independent predictors of fQRS presence in patients with MetS. Conclusions: Fragmented QRS is more common among MetS patients compared to non-MetS patients. The presence of fQRS is associated with pronounced subclinical LV systolic and diastolic dysfunctions in MetS patients.

Background: Mean platelet volume to platelet count (MPV/Plt) ratio has been demonstrated to be a good indicator of long-term mortality in patients with non-ST-segment elevation myocardial infarction (NSTEMI). However, the prognostic value of MPV/Plt in ST-elevation myocardial infarction (STEMI) is not reported. Aim: To determine whether the MPV/Plt ratio on admission has any predictive value for major adverse cardiac events includ­ing short- and long-term mortality in STEMI. Methods: In this prospective study, 470 STEMI patients who underwent primary percutaneous coronary intervention (PCI) were enrolled. The patients were divided into three tertiles based on the MPV/Plt ratio on admission. The first tertile (n = 149) was defined as MPV/Plt ratio ≤ 0.029, second tertile (n = 154) 0.029–0.038, and third tertile (n = 159) ≥ 0.038. Primary clinical outcomes consisted of the sum of cardiovascular (CV) mortality, non-fatal re-infarction, and stroke. Secondary clini­cal outcomes were CV mortality, non-fatal re-infarction, target-vessel revascularisation, stroke, and advanced heart failure. Results: There was no difference between study groups regarding the primary (p > 0.05) and the secondary outcomes (p > 0.05) except for one-year non-fatal re-infarction rate, which was found to be significantly higher in the highest MPV/Plt ratio group (p = 0.045). Age, Killip class > 1, and left ventricular ejection fraction were found to be independent predictors of long-term CV mortality in multivariate analysis (p = 0.009, p = 0.035, and p < 0.001, respectively). Conclusions: While the MPV/Plt ratio was demonstrated to be associated with one-year non-fatal re-infarction, it was not related to in-hospital, one-month, and one-year CV mortality in patients with STEMI, who underwent primary PCI.

OBJECTIVE Periprocedural myocardial injury (PMI) is known to be a predictor of in-hospital cardiac events and long-term adverse outcomes following a percutaneous coronary intervention (PCI). We aimed to evaluate the correlation between preprocedural serum lipid levels and PMI in patients undergoing elective PCI. PATIENTS AND METHODS The final study group included 195 patients (60.1±0.7 years old, 68 women and 127 men). Serum high-sensitive troponin T (hscTnT) concentrations were measured immediately before PCI and 12 h after PCI. Serum total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), and triglyceride (TG) levels were determined immediately before PCI. Serum hscTnT concentrations were adjusted for the clinical and procedural characteristics of the patients using the weighted least-square regression analysis. RESULTS The average preprocedural hscTnT concentration was 8.1±0.2 ng/l. The average serum hscTnT concentration increased to 34.1±2.8 ng/l (P

OBJECTIVE The total burden of subclinical coronary atherosclerosis is significant in young adults. Serum lipoprotein-associated phospholipase A2 (Lp-PLA2) is an established predictor of morbidity and mortality because of cardiovascular disease. The aim of the present investigation was to evaluate the relationship between subclinical coronary atherosclerosis and serum Lp-PLA2 concentrations in a population of young adults. PATIENTS AND METHODS A total of 261 individuals younger than 45 years of age who had undergone coronary computed tomography angiography were evaluated. The study group included 101 patients in whom coronary computed tomography angiography detected subclinical coronary atherosclerosis; the control group included 160 sex-matched and age-matched healthy control patients. RESULTS Serum Lp-PLA2 levels were increased significantly in the study group patients compared with the control patients (15.42±11.88 vs. 8.06±4.32 ng/ml, P

Background. Accelerated atherosclerosis and vascular calcification are common in chronic haemodialysis (HD) patients. In this study, we aimed to investigate the relationship between left ventricular hypertrophy (LVH) in HD patients and atherosclerosis and vascular calcification measured by electron beam computed tomography (EBCT). Methods. In a cohort of 118 HD patients (52 male, 66 female, mean age: 46±13 years), we measured biochemical parameters, including BUN, creatinine, albumin, haemoglobin, C-reactive protein and fibrinogen levels, and performed echocardiography, highresolution B-mode carotid ultrasonography and EBCT in 85 of them. The degree of stenosis was measured at four different sites (communis, bulbus, interna and externa) in both carotid arteries. Carotid plaque scores were calculated by summing the degrees of stenosis measured at all locations. Results. LVH was detected in 89 of the patients (75%). Plaque-positive patients had higher left ventricular mass index (LVMI) than plaque-negative patients (175±59 vs 143±46 g/m 2 , P ¼ 0.003). LVMI was correlated with systolic blood pressure (r ¼ 0.62, P

BACKGROUND Coronary artery calcification scores (CACS) calculated by electron beam computed tomography (EBCT) have been correlated with atherosclerotic burden in the non-uraemic population. However, the validity of this test in chronic haemodialysis patients (HD) is currently uncertain. In the present cross-sectional study, associations between carotid atherosclerosis and coronary calcification in HD patients are investigated. METHODS We studied 79 chronic HD patients (39 male, 40 female; mean age, 45+/-12 years). The mean time on HD was 68+/-54 months (range, 6-187 months). In these patients, we measured serum calcium, phosphorus, total cholesterol, cholesterol subgroups and iPTH levels. EBCT, echocardiography, and high-resolution B-mode carotid Doppler ultrasonography were also performed. RESULTS Plaque-positive HD patients had significantly higher CACS than plaque-negative patients (851+/-199 vs 428+/-185, mean+/-SE, P = 0.006). Coronary calcification scores were correlated with serum phosphorus (r = 0.37; P = 0.001). Only 8 of the 24 HD patients without coronary calcification had carotid plaques (33%), whereas 34 of the 53 patients with coronary calcification had carotid plaques (64%) (P = 0.015). Carotid plaque scores were correlated with CACS (r = 0.40; P = 0.001). A stepwise linear regression (model r = 0.72; P
