RESUMO

OBJECTIVE: Malignant pericardial effusion may affect almost 15 of the patients with underlying malignancies which deteriorates the prognosis. The prognostic significance of pericardial fluid cytology is under-represented in previous studies. METHODS: A total of 73 patients with symptomatic pericardial effusion treated with pericardiocentesis were included in this retrospective analysis. Macroscopic appearance, biochemical features, and cytological findings were obtained. Patients were divided into 3 groups: (i) without malignancy, (ii) with malignancy and negative cytology, and (iii) with malignancy and positive cytology. Survival data were searched via governmental death notification system. RESULTS: Mean age of the study group was 62 ± 15, and 54% (40) of the patients were female. On the cytological evaluation, 17 patients (23.3%) revealed positive cancer cytology, whereas 56 patients (76.7%) revealed negative cancer cytology. The median follow-up period was 840 days, and 34 patients (46.5%) died during follow-up. The survival rate of Group 3 was found to be significantly worse compared to Groups 1 and 2, no statistical difference was found between Groups 1 and 2 in terms of survival (Group 1 vs. Group 2 P =.078; Group 1 vs. Group 3 P <.001; Group 2 vs. Group 3 P =.041). CONCLUSION: Cytological evaluation is an important step in patients with malignant pericardial effusion. Positive pericardial fluid cytology indicates a poorer prognosis.

RESUMO

Aim    In this study, we aimed to investigate the role of sCD163 / tumor necrosis factor-like weak apoptosis-inducing (TWEAK) ratio in cardiac remodeling in non-elderly patients diagnosed with first acute myocardial infarction (MI).Material and Methods    Forty-four patients (age ranges: 40-64 years) diagnosed with first-time acute ST-elevation MI in the emergency department were evaluated with cardiac magnetic resonance (CMR) imaging. Adverse remodeling (AR) was defined the increases of left ventricular end-diastolic volume by ≥12 % by CMR at 6­month post-MI TWEAK and sCD163 were measured at the first day (baseline), 2 weeks and 6 weeks post-MI.Results    The average age of patients included in the study was 53.6±5.1 years. AR was detected in 18 patients at the 6 months post-MI. At the first day post-MI, median sCD163 concentration (116 069 vs 86 394 pg / mL, p=0.040) and median TWEAK concentration (759.4 vs 220.1 pg / mL, p<0.001) were higher in AR group compared to group without AR (the non-AR group), median sCD163 / TWEAK ratio (101.4 vs. 406.8; p<0.001) was lower. At the first day post-MI, concentrations of TWEAK and sCD163 showed a positive correlation in AR group and group without AR s. At 2 weeks post-MI, positive correlation continued in the non-AR group, but no significant correlation was found in the AR group. At the first day post-MI, sCD163 / TWEAK ratio was higher diagnostic performance compared to TWEAK and sCD163.Conclusion    In the early phase post-MI, the relationship between sCD163 - TWEAK may have an important role in AR pathogenesis. A lower sCD163 / TWEAK ratio on the first day after MI was associated with an increase in left ventricular end-diastolic volume after 6 months of follow-up.

RESUMO

BACKGROUND: The smoking paradox has been a matter of debate for acute myocardial infarction patients for more than two decades. Although there is huge evidence claiming that is no real paradox, publications supporting better outcomes in post-MI smokers are still being released. OBJECTIVE: To explore the effect of smoking on very long-term mortality after ST Elevation myocardial infarction (STEMI). METHODS: This study included STEMI patients who were diagnosed between the years of 2004-2006 at three tertiary centers. Patients were categorized according to tobacco exposure (Group 1: non-smokers; Group 2: <20 package*years users, Group 3: 20-40 package*years users, Group 4: >40 package*years users). A Cox regression model was used to estimate the relative risks for very long-term mortality. P value <0.05 was considered as statistically significant. RESULTS: There were 313 patients (201 smokers, 112 non-smokers) who were followed-up for a median period of 174 months. Smokers were younger (54±9 vs. 62±11, p: <0.001), and the presence of cardiometabolic risk factors were more prevalent in non-smokers. A univariate analysis of the impact of the smoking habit on mortality revealed a better survival curve in Group 2 than in Group 1. However, after adjustment for confounders, it was observed that smokers had a significantly increased risk of death. The relative risk became higher with increased exposure (Group 2 vs. Group 1; HR: 1.141; 95% CI: 0.599 to 2.171, Group 3 vs Group 1; HR: 2.130; 95% CI: 1.236 to 3.670, Group 4 vs Group 1; HR: 2.602; 95% CI: 1.461 to 4.634). CONCLUSION: Smoking gradually increases the risk of all-cause mortality after STEMI.


FUNDAMENTO: O paradoxo do fumante tem sido motivo de debate para pacientes com infarto agudo do miocárdio (IM) há mais de duas décadas. Embora haja muitas evidências demonstrando que não existe tal paradoxo, publicações defendendo desfechos melhores em fumantes pós-IM ainda são lançadas. OBJETIVO: Explorar o efeito do fumo na mortalidade de longo prazo após infarto do miocárdio por elevação de ST (STEMI). MÉTODOS: Este estudo incluiu pacientes com STEMI que foram diagnosticados entre 2004 e 2006 em três centros terciários. Os pacientes foram categorizados de acordo com a exposição ao tabaco (Grupo 1: não-fumantes; Grupo 2: <20 pacotes*anos; Grupo 3: 2-040 pacotes*anos; Grupo 4: >40 pacotes*anos). Um modelo de regressão de Cox foi utilizado para estimar os riscos relativos para mortalidade de longo prazo. O valor de p <0,05 foi considerado como estatisticamente significativo. RESULTADOS: Trezentos e treze pacientes (201 fumantes e 112 não-fumantes) foram acompanhados por um período médio de 174 meses. Os fumantes eram mais novos (54±9 vs. 62±11, p: <0,001), e a presença de fatores de risco cardiometabólicos foi mais prevalente entre os não-fumantes. Uma análise univariada do impacto do hábito de fumar na mortalidade revelou uma curva de sobrevivência melhor no Grupo 2 do que no Grupo 1. Porém, após ajustes para fatores de confusão, observou-se que os fumantes tinham um risco de morte significativamente maior. O risco relativo tornou-se maior de acordo com a maior exposição (Grupo 2 vs. Grupo 1: RR: 1,141; IC95%: 0,599 a 2.171; Grupo 3 vs. Grupo 1: RR: 2,130; IC95%: 1,236 a 3,670; Grupo 4 vs. Grupo 1: RR: 2,602; IC95%: 1,461 a 4,634). CONCLUSÃO: O hábito de fumar gradualmente aumenta o risco de mortalidade por todas as causas após STEMI.

RESUMO

AIM: Procalcitonin (PCT) is an inflammatory marker and elevated PCT levels are associated with cardiovascular events. We assessed whether PCT level is an independent predictor of bare-metal stent (BMS) in-stent restenosis (ISR). PATIENTS & METHODS: We evaluated 240 patients undergoing BMS implantation. Serum PCT levels were measured before procedure. Patients were classified as ISR(-) group (n = 120) and ISR(+) group (n = 120). RESULTS: Serum PCT levels were higher in the ISR (+) group (p < 0.001). At multivariate analysis, PCT (odds ratio [OR] 1.561; p = 0.012), stent length (OR: 1.089), stent diameter (OR: 0.141) and uric acid (OR: 1.465) were independent predictors of ISR. CONCLUSION: Serum PCT is independently associated with ISR and increased PCT levels may provide useful information for the risk of BMS-ISR.

RESUMO

The present study aimed to determine the long-term prognostic validity of the CHA2DS2-VASc score in patients with acute myocardial infarction (AMI). In addition, we formulated a novel scoring system, the CHA2DS2-VASc-CF (which includes cigarette smoking and a family history of coronary artery disease as risk factors). This study included 4373 consecutive patients with AMI who presented to the emergency department of our hospital and underwent cardiac catheterization procedures between December 2009 and September 2016. Among these patients, 1427 were diagnosed with ST elevation myocardial infarction (STEMI) and 2946 were diagnosed with non-STEMI. The study included 4373 patients. The study population was divided into 2 groups according to the occurrence of cardiovascular death during the follow-up period. Multivariate logistic regression analysis showed that the CHA2DS2-VASc-CF score, CHA2DS2-VASc score, major adverse cardiac events, current cigarette smoking, older age, hypertension, and family history of coronary artery disease were significantly higher, and that the left ventricular ejection fraction and glomerular filtration rate were significantly lower in the cardiovascular death (+) group. Using a cutoff score of >3 for the CHA2DS2-VASc-CF score, long-term cardiovascular death was predicted with a sensitivity of 78.4% and specificity of 76.4%. The CHA2DS2-VASc-CF score is suitable for use in all patients with AMI, regardless of the type of treatment, presence of atrial fibrillation, and type of AMI. This risk score, which is easy to calculate, provides important prognostic data. In the future, we think that interventional cardiologists will be able to use this novel scoring system to identify patients with a high risk of long-term cardiovascular death.

RESUMO

We investigated the relationship between endocan (a marker of systemic inflammation) and the development of coronary collateral circulation (CCC) as evaluated by coronary angiography in patients with chronic stable angina pectoris. A total of 90 patients (32 poor CCC and 58 good CCC) were included in this study. Endocan levels were determined using a commercially available sandwich enzyme-linked immunosorbent assay kit with high sensitivity and specificity for detection of human endocan. In multivariate logistic regression analysis, low endocan levels were independently associated with good CCC ( P < .001). Moreover, low high-sensitivity C-reactive protein levels were also independently associated with good CCC ( P = .020). We found an optimal cutoff point for endocan of 1.7 ng/mL; it predicted the presence of good CCC with a sensitivity of 72.4% and specificity of 65.6% ( P < .001). The results of the present study suggest that measurement of endocan level may help clinicians to predict the development of CCC in patients with stable coronary artery disease.

RESUMO

We examined the impact of the preprocedural triglyceride (TG)/high-density lipoprotein cholesterol (HDL-C) ratio on risk of in-stent restenosis (ISR). Patients with typical anginal symptoms and/or positive treadmill or myocardial perfusion scintigraphy test results who underwent successful coronary stent implantation due to stable angina were examined; 1341 patients were enrolled. The hospital files of the patients were used to gather data. Cox regression analysis showed that the TG/HDL-C ratio was independently associated with the presence of ISR ( P < .001). Moreover, diabetes mellitus ( P = .007), smaller stent diameter ( P = .046), and smoking status ( P = .001) were also independently associated with the presence of ISR. Using a cutoff of 3.8, the TG/HDL-C ratio predicted the presence of ISR with a sensitivity of 71% and a specificity of 68%. Also, the highest quartile of TG/HDL-C ratio had the highest rate of ISR ( P < .001). Measuring preprocedural TG/HDL-C ratio, in fasting or nonfasting samples, could be beneficial for the risk assessment of ISR. However, further large-scale prospective studies are required to establish the exact role of this simple, easily calculated, and reproducible parameter in the pathogenesis of ISR.

RESUMO

BACKGROUND: The aim of this study was to investigate the relationship between endocan levels with the presence of slow coronary flow (SCF). METHODS: In this cross-sectional study, a total of 88 patients, who admitted to our hospital, were included in this study. Of these, 53 patients with SCF and 35 patients with normal coronary flow were included in the final analysis. Coronary flow rates of all patients were determined by the Timi Frame Count (TFC) method. RESULTS: In correlation analysis, endocan levels revealed a significantly positive correlation with high sensitive C-reactive protein and corrected TFC. In multivariate logistic regression analysis, the endocan levels were found as independently associated with the presence of SCF. Finally, using a cutoff level of 2.3, endocan level predicted the presence of SCF with a sensitivity of 77.2% and specificity of 75.2%. CONCLUSION: In conclusion, our study showed that higher endocan levels were significantly and independently related to the presence of SCF.

RESUMO

We assessed the prognostic role of serum endocan level in patients with ST-segment elevation myocardial infarction (STEMI) and compared the results with a normal coronary angiography group. A total of 133 patients were included in the study (88 patients with STEMI and 45 patients with normal coronary arteries). The SYNTAX score was determined based on the baseline coronary angiogram. Multivariate logistic regression analysis indicated that endocan independently correlated with the presence of STEMI. Moreover, high-sensitivity C-reactive protein (hsCRP), peak troponin I, and left ventricular ejection fraction (LVEF) were found to be independently associated with STEMI. Endocan level correlated significantly with hsCRP and SYNTAX score. We analyzed the discriminatory capability of endocan level for the presence of STEMI using a receiver-operating characteristics curve. A cutoff endocan level of 1.7 (ng/mL) predicted the presence of STEMI with a sensitivity of 76.1% and specificity of 73.6%. In conclusion, a high endocan level on hospital admission is an independent predictor of a worse cardiovascular outcome and a high SYNTAX score in patients with STEMI.

RESUMO

OBJECTIVE: In this study, we aimed to investigate the relation of platelet to lymphocyte ratio (PLR) in saphenous vein graft disease (SVGD) in patients with stable angina pectoris after coronary artery bypass graft surgery. METHODS: A total of 455 patients were included in the study. There were 210 patients with SVGD and 245 patients without SVGD. The effects of different variables on SVGD were computed in logistic regression analysis. RESULTS: The platelet count, lymphocyte count, PLR, high-density lipoprotein (HDL), Na, and ALT were significantly associated with SVGD. In multivariate regression analysis, HDL and PLR were found to be significantly associated with SVGD. CONCLUSION: To the best of our knowledge, this is the first study showing the significant association of PLR with SVGD. This study suggests that PLR can be used as a marker of SVGD because it is an easily available and inexpensive test.

RESUMO

BACKGROUND: The pathophysiology of coronary artery ectasia (CAE) is still unknown. Inflammation and degradation of connective tissue may have a role in the development of coronary ectasia. In the present study, the authors examined neutrophil gelatinase-associated lipocalin (NGAL) levels in isolated CAE patients. METHODS: Thirty-five patients with isolated CAE (25 males; mean age, 59±10 years) and 35 age- and sex-matched healty volunteers (22 males; mean age, 57±11 years) who had been shown to have normal coronary arteries were included in the study. Basal characteristics were recorded. Serum NGAL levels were determined with an enzyme-linked immunosorbent assay kit. RESULTS: NGAL levels were significantly higher in the isolated CAE group than in the control group (65.1±13 vs 53.7±19 ng/mL; P=0.006). There were also significant difference in NGAL levels according to the number of ectatic coronary arteries (58.1±13, 70.9±9, and 71.1±11 ng/mL for 1, 2, and 3 arteries, respectively; P=0.015). Level of NGAL was lowest in patients who have only 1 ectatic coronary artery. CONCLUSION: Serum NGAL levels increased in patients with isolated CAE, and NGAL may play a crucial role in the development and/or progression of coronary artery ectasia.

RESUMO

BACKGROUND: Fractional flow reserve (FFR) is an invasive method to assess the functional significance of coronary stenoses. The value of FFR in diabetic patients is controversial because of microvascular dysfunction. The aim of this study is to investigate the effect of diabetes mellitus (DM) on FFR measurements. METHODS: One hundred and twenty-one patients with an intermediate lesion who had undergone FFR measurement were included in the study. Lesion severity was determined by quantitative coronary angiography. The patients were divided into groups according to the presence (group 1) or absence (group 2) of DM. The patients were further categorized according to the degree of luminal narrowing caused by the lesion (40-50, 51-60, and >60%) and reference vessel diameter (> or = 2.8 and <2.8 mm). FFR measurements were compared in each category. RESULTS: There was no difference between the FFR values of diabetic and nondiabetic patients who had coronary lesions with similar degree of luminal narrowing (0.87+/-0.08 vs. 0. 0.85+/-0.07; 0.81+/-0.08 vs. 0.82+/-0.10; 0.81+/-0.10 vs. 0.83+/-0.09, P = 0.957). In the analysis comparing FFR measurements in the categories set according to reference vessel diameter, we did not find a difference either (0.82+/-0.09 vs. 0.83+/-0.09; 0.84+/-0.09 vs. 0.82+/-0.09, P = 0.878). The DeltaFFR value, which is the difference between FFR values before and after adenosine administration, was also similar in diabetic and nondiabetic patients (8.4+/-6.0 vs. 8.4+/-5.5, P = 0.997). CONCLUSION: The presence of DM does not have a significant impact on FFR values in coronary stenoses of intermediate severity.
