RESUMO
BACKGROUND: Infective endocarditis (IE) is still a significant cause of morbidity and mortality among cardiovascular diseases. ENDOCARDITIS-TR study aims to evaluate the compliance of the diagnostic and therapeutic methods being used in Turkey with current guidelines. METHODS: The ENDOCARDITIS-TR trial is a multicentre, prospective, observational study consisting of patients admitted to tertiary centres with a definite diagnose of IE. In addition to the demographic, clinical, microbiological, and echocardiographic findings of the patients, adverse events, indications for surgery, and in-hospital mortality were recorded during a 2-year time interval. RESULTS: A total of 208 IE patients from 7 tertiary centres in Turkey were enrolled in the study. The study population included 125 (60.1%) native valve IE (NVE), 65 (31.3%) prosthetic IE (PVIE), and 18 (8.7%) intracardiac device-related IE (CDRIE). One hundred thirty-five patients (64.9%) were culture positive, and the most frequent pathogenic agent was methicillin-susceptible Staphylococcus aureus (MSSA) (18.3%). Among 155 (74.5%) patients with an indication for surgery, only 87 (56.1%) patients underwent surgery. The all-cause mortality rate was 29.3% in-hospital follow-up. Multivariable Cox regression analysis revealed that absence of surgery when indicated (HR: 3.29 95% CI: 0.93-11.64 p = 0.05), albumin level at admission (HR: 0.46 95% CI: 0.29-0.73 P < 0.01), abscess formation (HR: 2.11 95% CI: 1.01-4.38 p = 0.04) and systemic embolism (HR: 1.78 95% CI: 1.05-3.02 p = 0.03) were ascertained independent predictors of in-hospital all-cause mortality. DISCUSSION: The short-term results of the ENDOCARDITIS-TR trial showed the high frequency of staphylococcal IE, relatively high in-hospital mortality rates, shortage of surgical treatment despite guideline-based surgical indications and low usage of novel imaging techniques. The results of this study will provide a better insight to physicians in respect to their adherence to clinical practice guidelines.

BACKGROUND: Despite the high proportion of octogenarians with acute pulmonary embolism, there is little information indicating the optimal management strategy, mainly therapeutic measures, such as lytic therapy. OBJECTIVES: The number of elderly patients diagnosed with acute pulmonary embolism increases constantly. However, the role of thrombolytic treatment is not clearly defined among octogenarians. Our objective is to evaluate the effectiveness of lytic therapy in octogenarian patients diagnosed with pulmonary embolism. METHODS: One hundred and forty eight subjects (70.3% women, n=104) aged more than eighty years were included in the study. The patients were divided in two groups: thrombolytic versus non-thrombolytic treatment. In-hospital mortality rates and bleeding events were defined as study outcomes. P-value <0.05 was considered as statistical significance. RESULTS: In-hospital mortality decreased significantly in the thrombolytic group compared to the non-thrombolytic group (10.5% vs. 24.2% p=0.03). Minor bleeding events were more common in the arm that received thrombolytic treatment, but major hemorrhage did not differ between the groups (35.1% vs. 13.2%, p<0.01; 7% vs. 5.5% p=0.71, respectively). High PESI score (OR: 1.03 95%CI; 1.01-1.04 p<0.01), thrombolytic therapy (OR: 0.15 95%CI; 0.01-0.25, p< 0.01) and high troponin levels (OR: 1.20 95%CI; 1.01-1.43, p=0.03) were independently associated with in-hospital mortality rates in the multivariate regression analysis. CONCLUSION: Thrombolytic therapy was associated with reduced in-hospital mortality at the expense of increased overall bleeding complications in octogenarians.
FUNDAMENTO: Apesar da grande proporção de octogenários com embolia pulmonar aguda, há pouca informação indicando a estratégia de manejo ideal, especialmente medidas terapêuticas, como a terapia lítica. OBJETIVOS: O número de pacientes idosos diagnosticados com embolia pulmonar aguda aumenta constantemente. Porém, o papel do tratamento trombolítico não está claramente definido entre os octogenários. Nosso objetivo é avaliar a efetividade da terapia lítica em pacientes octogenários diagnosticados com embolia pulmonar. MÉTODOS: Cento e quarenta e oito indivíduos (70,3% de mulheres, n=104) com mais de 80 anos foram incluídos no estudo. Os pacientes foram divididos em dois grupos: tratamento trombolítico versus não-trombolítico. As taxas de mortalidade hospitalar e episódios de sangramento foram definidos como desfechos do estudo. Valor de p <0,05 foi considerado como estatisticamente significativo. RESULTADOS: A mortalidade hospitalar reduziu significativamente no grupo trombolítico em comparação ao não-trombolítico (10,5% vs. 24,2%; p=0,03). Episódios de sangramento menores foram mais comuns no braço que recebeu o tratamento trombolítico, mas grandes hemorragias não diferiram entre os grupos (35,1% vs. 13,2%, p<0,01; 7% vs. 5,5% p=0,71, respectivamente). O escore de PESI alto (OR: 1,03 IC95%; 1,01-1,04 p<0,01), a terapia trombolítica (OR: 0,15 IC95%; 0,01-0,25, p< 0,01) e níveis altos de troponina (OR: 1,20 IC95%; 1,01-1,43, p=0,03) estiveram independentemente associados a taxas de mortalidade hospitalar na análise de regressão multivariada. CONCLUSÃO: A terapia trombolítica esteve associada à mortalidade hospitalar reduzida em detrimento do aumento geral das complicações de sangramento em octogenários.

OBJECTIVE: The effect of malnutrition in patients with ST segment elevation myocardial infarction (STEMI) is not fully understood. In this study, we tried to investigate the prognostic consequence of the Controlling Nutritional Status (CONUT) score in patients with STEMI. METHODS: In this study, we evaluated the CONUT scores of 1,028 patients with STEMI and examined its relationship with major adverse cardiovascular events (MACE) (all-cause mortality, myocardial reinfarction, and vessel revascularization) during a period of 19.9±10.3 months. Patients with CONUT score ≥5 were defined as severely malnourished. Predictors of MACE were assessed by Cox regression analysis, and p<0.05 was considered to indicate statistical significance. RESULTS: MACE was observed in a total of 147 (14.3%) patients. MACE was more frequent in the group with a higher CONUT score (33.3% vs. 10.9%, p<0.001). CONUT score ≥5 was an independent predictor of MACE in the Cox regression analysis (hazard ratio=2.50, 95% confidence interval: 1.61-3.90, p<0.001). Low ejection fraction, Killip class ≥3 at presentation, thrombolysis in myocardial infarction flow grade <3 after intervention, left main artery involvement, and low hemoglobin levels were other independent predictors of MACE in the long-term follow-up. Kaplan-Meier curves showed decreased MACE free survival rates in the high CONUT score group at a mean 19.9±10.3 months' follow-up duration (log-rank p<0.01). CONCLUSION: Malnutrition was strongly associated with poor outcomes in patients with STEMI treated using primary percutaneous coronary intervention.

OBJECTIVES: Patients with postoperative atrial fibrillation (POAF) have increased risk of both short- and long-term mortality and morbidity; therefore, prediction of POAF is crucial in the preoperative period of the patients undergoing coronary artery bypass graft surgery. Electrocardiography (ECG) is the simplest and cost-effective tool in the preoperative workup of the patients for the prediction of POAF. A newly defined ECG parameter P wave peak time (PWPT) has been shown as a marker of atrial fibrillation development in non-surgical patients and we investigated its role in patients undergoing cardiac surgery. METHOD: A total of 327 patients undergoing isolated or combined cardiac surgery were involved and the primary endpoint was defined as the development of POAF. The study population was divided into two groups based on the presence or absence of POAF. Groups were compared for both standard P wave parameters and for PWPT on surface ECG. The predictors of POAF were assessed by multivariate regression analysis. RESULTS: The frequency of POAF was 20.4% (n = 67). P wave peak time in leads D2 (65.1 ± 11.8 vs 57.2 ± 10, p < 0.01) and V1 (57.8 ± 18 vs 44.8 ± 12.3, p < 0.01) were longer in patients with POAF. In multivariate regression analysis, PWPT in leads DII and V1 were independent predictors of POAF (OR: 1.11, 95%CI: 1.02-1.21, p = 0.01, OR: 1.06, 95%CI: 1.00-1.13, p = 0.03 respectively). CONCLUSION: PWPT in leads DII and V1 can predict the development of POAF in patients undergoing cardiac surgery.

Introduction: In this study, we aimed to determine if neutrophil to lymphocyte ratio could predict long term morbidity and mortality in patients who hospitalized for non-ST segment elevation acute coronary syndrome (NSTE-ACS) and had coronary slow flow on coronary angiography. Methods: In this observational study, 111 patients who presented with NSTE-ACS and diagnosed with coronary slow flow phenomenon on angiographic examination were included. Neutrophil to lymphocyte ratio (NLR) calculated as the ratio of the number of neutrophils to the number of lymphocytes. Patients classified into three groups according to NLR values. The term coronary slow flow phenomenon was depicted by calculating Thrombolysis in Myocardial Infarction frame count.Patients were followed up and the occurrence of recurrent angina, recurrent myocardial infarction, and long-term mortality was determined using medical records, phone calls, or face-to-face interviews. P values <0.05 considered to indicate statistical significance. Results: Recurrent angina and myocardial infarction occurred more frequently in the highest NLR tertile compared with middle and lowest NLR tertiles. High NLR group (NLR≥ 3.88 n=38) was significantly associated with younger age and smoking status. WBC, troponin I and CRP levels increased as the NLR tertile increased. Recurrent myocardial infarction and angina showed strong relationship with increasing NLR values. In multivariate regression analyses smoking and high NLR levels were independent predictors of recurrent myocardial infarction (HR:4.64 95%CI 0.95-22.52 P=0.04, HR: 1.48 95%CI 1.16-1.90 P<0.01 respectively) in the long term follow up. Conclusion: Our study demonstrated that high NLR values can be a valuable prognostic tool in the long term follow up of patients who presented with NSTE-ACS and diagnosed with slow flow phenomenon on coronary angiography.
RESUMO
BACKGROUND: Digoxin treatment has come under scrutiny in recent years after reports from several studies that it is associated with increased mortality in patients with atrial fibrillation (AF). The clinical effects of digoxin on mortality were closely related to serum digoxin concentrations (SDC) in these studies. In the present work, we evaluated the role of the SAMe-TT2R2 and modified SAMe-TT2R2 scores in predicting the therapeutic range of digoxin therapy. METHODS: Medical records from our institution were screened for patients who were under digoxin treatment between 2008 and 2018. A total of 2418 patients for whom SDC were recorded were included in the study. An SDC of <0.5 or >1.2â¯ng/ml was defined as being out of the therapeutic range (oTR). RESULTS: In multivariable regression analyses, abnormal body mass index (odds ratio [OR]: 1.59, 95% confidence interval [CI]: 1.29-1.95, pâ¯< 0.01), white blood cell count (OR: 1.12, 95% CI: 1.01-1.27, pâ¯< 0.01), and the modified SAMe-TT2R2 score (OR: 4.19 95% CI: 3.71-4.72, pâ¯< 0.01) were determined to be independent predictors of oTR. A modified SAMe-TT2R2 score greater than 3 predicted oTR with a sensitivity of 86% and a specificity of 65% (AUC: 0.825, pâ¯< 0.01). CONCLUSION: Digoxin is still widely used in the treatment of heart failure and AF despite concerns about the increased risk of mortality when levels are oTR. In the present study, the modified SAMe-TT2R2 score was found to be an independent predictor of oTR. This score may aid clinicians in identifying patients who are more likely to benefit from digoxin therapy.

OBJECTIVE: Despite wide usage of digoxin for various diseases in cardiology practice, its benefit is controversial and moreover it had been associated with unfavorable outcomes in some previous studies. The aim of this present study was to demonstrate whether digoxin usage was related with worse outcomes or not in patients with acute pulmonary embolisms. METHODS: A total number of 1215 patients retrospectively enrolled for the study. Basic demographic features, pulmonary embolism severity index (PESI) scores, laboratory parameters and medications of patients who had been diagnosed with acute pulmonary embolism were recorded. Short (30 days) and long-term mortality were reported as the clinical outcomes. RESULTS: Total mortality was 15.4% in the study population and 78 of these subjects died within the first 30 days. The frequency of digoxin treatment was 8% and most of these patients were prior users. According to the binary logistic regression analyses the PESI score, right ventricle (RV) diastolic diameter, systolic pulmonary arterial pressure (sPAP), brain natriuretic peptide (BNP), troponin and digoxin therapy (odds ratio, OR: 2.82 95% confidence interval, CI: 1.39-8.31, Pâ¯= 0.03) were found as independent predictors of short-term mortality. Beside these findings; sPAP, PESI score, RV diastolic diameter and digoxin therapy (hazard ratio, HR: 2.11 95%CI: 1.22-7.31, Pâ¯= 0.03) were determined as independent predictors of long-term mortality in Cox regression analyses. In subgroup analysis, we determined significantly greater increase in short-term mortality with use of digoxin among patients who had chronic renal disease, among patients under thrombolytic therapy and under high dosage of digoxin therapy and among female patients. CONCLUSION: Digoxin has been used extensively for decades in the treatment of heart failure and arrhythmias despite some controversies over its benefit. For the first time in the literature, we have demonstrated independent association of digoxin therapy with short-term and long-term mortality in patients with acute pulmonary embolism.

Introduction: In-stent restenosis (ISR) still constitutes a major problem after percutaneous vascular interventions and the inflammation has a pivotal role in the pathogenesis of such event. The C-reactive protein/albumin ratio (CAR) is a newly identified inflammatory biomarker, and it may be used as an indicator to predict ISR in subjects with coronary artery stenting. In light of these data, our main objective was to investigate the relationship between the preprocedural CAR and ISR in patients undergoing successful iliac artery stent implantation. Methods: In total, 138 consecutive patients who had successful iliac artery stent implantation in a tertiary heart center between 2015 and 2018 were enrolled in the study. The study population was categorized into two groups; patients with ISR and those without ISR during follow-up. The CAR was determined by dividing CRP by serum albumin. Results: In the multivariable regression analysis; the CAR (HR: 2.66, 95% CI: 1.66-4.25, P < 0.01), stent length (HR: 1.01, 95% CI: 0.99-1.02, P = 0.04), and HbA1c levels (HR: 1.22, 95% CI: 0.99-1.51, P = 0.04) were independently related with ISR. A receiver operating curve analysis displayed that the CAR value of >0.29 predicted ISR with sensitivity of 97.5% and specificity of 88.8% (AUC 0.94, P < 0.01). Conclusion: Our findings provide evidence that the CAR may be an applicable inflammatory biomarker in predicting ISR in subjects undergoing iliac artery stenting for the treatment of peripheral artery disease (PAD). Also, the stent length and poor glycemic control were found to be associated with ISR.
RESUMO
Background: The main objective of the current study is to find out if any association exists between specific inflammatory markers such as homocysteine (Hcy) and pentraxin-3 (PTX-3) and cardiac involvement determined by means of echocardiographic parameters in patients with Behçet disease (BD).Methods: From January 2011 to January 2012, a total of 62 Behçet's patients were enrolled in the study. Thirty-two healthy subjects constituted the control group. The diagnosis of BD was made as proposed by International Study Group of BD.Results: The mean PTX-3, Hcy, and C-reactive protein levels were significantly higher in patients with BD compared to the control group. The electromechanical delay (EMD) times were found to be prolonged in patients with BD. Also, the aortic stiffness index (SI) and elastic modulus (Ep) were significantly higher, while the aortic dispensibility was significantly lower in patients with BD. The left atrial volume, left atrial volume index, E/A ratio, E/E' septal, IRight-EMD, PA'-ML, PA'-MS, PA'-TL, SI, and Ep were correlated with PTX-3 levels. In addition, the E/A, PA'-ML, PA'-MS, SI, and Ep displayed correlation with Hcy levels in patients having BD.Conclusion: Elevated levels of PTX-3 and Hcy were found to be correlated with cardiac involvement determined by means of echocardiographic parameters in patients with BD.

Background: Lead aVR provides prognostic information in various settings for patients with cardiovascular diseases. The present study aimed to investigate the prognostic value of a positive T wave in lead aVR (TaVR) for patients with acute pulmonary embolism (APE).Methods: We screened a total of 412 consecutive patients who were hospitalised with a diagnosis of APE between 2008 and 2018. We investigated electrocardiograms (ECGs) for the presence of a positive TaVR and classified other abnormal ECG findings. Additionally, clinical data, such as echocardiographic findings were recorded, and pulmonary embolism severity index (PESI) scores were calculated. The predictors of mortality at 30 days were investigated as the clinical outcome by logistic regression analysis.Results: In our study population, 54 patients (13.1%) died within 30 days. The prevalence of female gender, congestive heart failure, chronic obstructive pulmonary disease, and mean PESI scores were significantly higher in patients with a positive TaVR compared to those without it. Systolic blood pressure of patients with positive TaVR was significantly lower than that of patients without positive TaVR. In multivariate regression analysis; PESI scores (OR: 1.03; 95% CI: 1.01-1.04, p < .01), Right ventricular end-diastolic diameter (RVEDD) (OR: 1.07 95% CI: 1.01-1.13, p = .02), and a positive TaVR (OR: 4.41; 95% CI: 1.63-11.96, p < .01) were independently correlated with mortality.Conclusion: Positive TaVR, PESI scores, and RVEDD at hospital admission may have prognostic value in patients with APE. Positive T wave in lead aVR could be a useful marker in early risk stratification of pulmonary embolism.

BACKGROUND: Because myocardial infarction in young adults is rare, there has been limited research on the condition in this patient group. Very few data are available regarding the long-term outcomes of patients under 40 years of age with non-ST-segment elevation myocardial infarction (NSTEMI) undergoing invasive treatments. The prognostic value of uric acid (UA) in young patients with NSTEMI who undergo percutaneous coronary intervention (PCI) has also not been studied. The purpose of this study was to evaluate the long-term clinical outcomes of this specific subset of young patients. In addition, we aimed to identify the role of serum UA in predicting the long-term prognosis of young patients with NSTEMI who have undergone PCI. METHODS: We performed a retrospective analysis of 213 young adult patients (≤40 years old) with NSTEMI who underwent PCI during their hospitalization at our tertiary referral center. RESULTS: The mean age of the 213 patients was 36.8⯱ 3.3 years (range, 21-40 years). The median follow-up was 930 days. Our patients were predominantly male (88.3%) and the most frequent traditional cardiovascular risk factors were smoking and dyslipidemia. Baseline TIMI flow 0-1, estimated glomerular filtration rate (eGFR), and UA were found to be independently correlated with long-term major adverse cardiovascular events (MACEs) in multivariate Cox regression analysis. CONCLUSION: In the present study, baseline TIMI flow 0-1, admission eGFR, and UA levels were correlated with MACEs during long-term follow-up in young patients with NSTEMI.

Fistula from left internal mammary artery (LIMA) to pulmonary artery (PA) is rarely encountered in daily practice. In recent years, endovascular therapy options have emerged for the treatment of fistula formations and replaced with surgery. A 53-year-old man admitted to our outpatient clinic with symptoms of typical angina and shortness of breath despite optimal medical therapy. In his relevant history, he had a coronary artery bypass graft (CABG) operation in 2009 in which his LIMA was anastomosed to left anterior descending (LAD) and ramus artery sequentially. Coronary angiography including selective imaging of LIMA demonstrated a fistula formation originating from the proximal portion of the LIMA and draining to PA. After successful closure of fistula with transcatheter coil embolization, the patient was discharged without any complication and symptom. In conclusion, although LIMA to PA fistula is an infrequent clinical condition, it should be considered as a potential cause of persistent angina after CABG operation. Treatment options include conservative medical therapy, surgical ligation and endovascular interventions. The best therapy should be individualised for each patient in respect to patient's symptoms, surgical compatibility and anatomy of fistula.

OBJECTIVE: Monocyte to high-density lipoprotein ratio (MHR) has recently been postulated as a novel parameter related to adverse cardiovascular outcomes. In this study, we aimed to investigate the correlation of MHR with stent restenosis (SR) rates after the primary percutaneous coronary intervention (PCI) and bare-metal stent (BMS) implantation. METHODS: In this study, patients who had undergone primary PCI for STEMI and had a control angiogram during follow-up were retrospectively recruited. Patients were categorized according to admission MHR tertiles, clinical and angiographic data were compared. In addition, predictors of SR were evaluated with logistic regression analysis. RESULTS: A total number of 448 patients (240 patients with SR and 208 patients without SR) were included in this study. Patients were categorized into three groups according to tertiles of admission MHR. During a follow-up period of median 12 months, the rate of SR was significantly higher in patients with higher MHR levels (45% in tertile 1, 54% in tertile 2 and 62% in tertile 3, p<0.01). In multivariate Cox regression analysis, male gender, stent length, admission NLR levels and MHR levels (HR 1.03, 95% CI 1.02-1.06, p<0.01) remained as the independent predictors of SR in the study population. CONCLUSION: Gender, stent length, higher MHR and NLR levels are correlated to SR after primary PCI.
RESUMO
BACKGROUND: An increased risk of ischemic stroke has been reported in patients with Parkinson's disease (PD). Atrial fibrillation (AF) is strongly associated with ischemic stroke. Prolonged atrial electromechanical delay (EMD) is an independent predictor for the development of AF. AIMS: The aim of the present study was to evaluate the atrial conduction parameters in patients with PD and to assess their relation with the severity of PD. STUDY DESIGN: We prospectively enrolled 51 consecutive patients with newly diagnosed PD and 31 age- and sex-matched non-PD subjects. METHODS: To assess atrial electromechanical coupling (PA), the time intervals from the onset of p wave on ECG to the late diastolic wave at the septal (PAs) and lateral (PAl) mitral annulus and lateral tricuspid annulus (PAt) were measured on Tissue Doppler Echocardiography (TDE). The difference between PAs-PAl, PAs-PAt, and PAl-PAt were defined as left intra-atrial, right intra-atrial, and interatrial EMD, respectively. P-wave dispersion (PWD) was calculated from the 12-lead ECG. RESULTS: PWD, PAs, PAl, and PAt durations were significantly prolonged in the PD group (all p < 0.001). Interatrial, right, and left intra-atrial EMD were also significantly longer in PD patients (p < 0.001, p < 0.001 and p=0.002, resp.). There were significant positive correlations between disease severity (UPDRS score) and PWD (r=0.34, p=0.041), left intra-atrial (r=0.39, p=0.005), and interatrial EMD (r=0.35, p=0.012). By multivariate analysis, PWD (OR: 1.13, 95% CI: 1.02-1.25; p=0.017), LA volume index (OR: 1.19, 95% CI: 1.02-1.37; p=0.021), left intra-atrial (OR: 1.12, 95% CI: 1.01-1.24; p=0.041), and interatrial EMD (OR: 1.08, 95% CI: 1.01-1.16; p=0.026) were found as independent predictors of PD. CONCLUSION: Atrial conduction times were longer and correlated with the severity of disease in PD patients. Prolonged inter- and intra-atrial-EMD intervals were also found as independent correlates of PD. These findings may suggest an increased predisposition to atrial fibrillation in PD.
RESUMO
BACKGROUND: Warfarin-related nephropathy (WRN) is a complication of warfarin over-anticoagulation that is associated with acute and/or chronic renal dysfunction and increased mortality. The long-term effects of warfarin on renal function has not been adequately studied in patients with a mechanical prosthetic valve (MPV). AIM: To study the time-dependent effects of over-anticoagulation on renal function in patients with a MPV. METHODS: A total of 193 patients who underwent MPV implantation and were followed up in this study were eligible for inclusion. Time above therapeutic international normalized ratio (INR) range (TATR) was calculated by dividing the number of INR measurements above target in a year by the total number of INR measurements within a year. Patients were divided into quartiles according to average TATR at 60 months. RESULTS: At 60 months more patients within the 4th quartile had a ≥20% reduction in the estimated glomerular filtration rate (eGFR, 25.0%, pâ¯= 0.04) and chronic kidney disease (CKD, 33.0%, pâ¯= 0.07) compared to patients within the 1st quartile. High TATR remained a significant determinant for reduction in eGFR (odds ratio OR: 7.50, 95% confidence interval CI:1.55-36.32) and CKD (OR:5.15, 95% CI: 1.26-20.62) after adjusting for other variables. Longitudinal analysis revealed that the change in eGFR was related to the duration of warfarin use (pâ¯< 0.001) and the interaction between the duration of warfarin use and TATR (pâ¯= 0.03). Similar findings were observed in patients without CKD at baseline, but not in those with CKD before the index operation. CONCLUSION: Anticoagulation over targeted INR values is associated with a steeper decline in eGFR and an increased frequency of CKD in patients with a MPV.

OBJECTIVE: An intra-aortic balloon pump (IABP) is a mechanical support device that is used in addition to pharmacological treatment of the failing heart in intensive cardiac care unit (ICCU) patients. In the literature, there are limited data regarding the clinical characteristics and in-hospital outcomes of acute coronary syndrome patients in Turkey who had an IABP inserted during their ICCU stay. This study is an analysis of the clinical characteristics and outcomes of these acute coronary syndrome patients. METHODS: The data of patients who were admitted to the ICCU between September 2014 and March 2017 were analyzed retrospectively. The data were retrieved from the ICCU electronic database of the clinic. A total of 142 patients treated with IABP were evaluated in the study. All of the patients were in cardiogenic shock following percutaneous coronary intervention, at the time of IABP insertion. RESULTS: The mean age of the patients was 63.0±9.7 years and 66.2% were male. In-hospital mortality rate of the study population was 54.9%. The patients were divided into 2 groups, consisting of survivors and non-survivors of their hospitalization period. Multivariate analysis after adjustment for the parameters in univariate analysis revealed that ejection fraction, Thrombolysis in Myocardial Infarction flow score of ≤2 after the intervention, chronic renal failure, and serum lactate and glucose levels were independent predictors of in-hospital mortality. CONCLUSION: The mortality rate remains high despite IABP support in patients with acute coronary syndrome. Patients who are identified as having a greater risk of mortality according to admission parameters should be further treated with other mechanical circulatory support devices.

OBJECTIVE: Pathological studies have suggested that local inflammation, particularly eosinophilic infiltration of the adventitia, could be related to nonatherosclerotic spontaneous coronary artery dissection (NA-SCAD). However, the role of systemic inflammation in the pathogenesis of NA-SCAD remains unknown. Our aim was to investigate systemic inflammatory activation in patients with an acute coronary syndrome (ACS) secondary to NA-SCAD. METHODS: The institutional electronic medical database was reviewed, and 22 patients with NA-SCAD-ACS were identified after the review. Furthermore, 30 random patients with CAD-ACS and 30 random subjects without any history of CAD or ACS with demographic and clinical characteristics similar to those of NA-SCAD-ACS patients were identified from the institutional database to be included in the study. RESULTS: Patients with NA-SCAD-ACS and those with CAD-ACS both had higher white blood cell and neutrophil counts than controls. Neutrophil-lymphocyte ratio (NLR) and C-reactive protein (CRP) levels were only significantly higher in the NA-SCAD-ACS group [2.01 (1.54-6.17) for NLR and 0.70 (0.13-2.70) for CRP] than in the controls [1.55 (1.27-2.13), p=0.03 for NLR and 0.15 (0.10-0.43), p=0.049 for CRP]; however, there were no differences between the NA-SCAD-ACS and CAD-ACS groups [1.91 (1.41-2.78) for NLR and 0.41 (0.09-1.10) for CRP, p>0.05 for both comparisons] regarding all tested parameters. CONCLUSION: The degree of inflammatory activation in NA-SCAD-ACS patients was similar to, or even greater than, that in CAD-ACS patients; thus, suggesting a role of inflammation in the pathophysiology of NA-SCAD-ACS.
RESUMO
BACKGROUND: Acute pulmonary embolism (PE) is a serious clinical disease characterized by a high mortality rate. The aim of this study was to assess the prognostic value of international normalized ratio (INR) in acute PE patients not on anticoagulant therapy. METHODS: The study included 244 hospitalized acute PE patients who were not receiving previous anticoagulant therapy. Based on their 30-day mortality, patients were categorized as survivors or non-survivors. INR was measured during the patients' admission, on the same day as the diagnosis of PE but before anticoagulation started. RESULTS: Thirty-day mortality occurred in 39 patients (16%). INR was higher in non-survivors than in survivors (1.3±0.4 vs 1.1±0.3, P=.003). In multivariate analysis, INR (HR: 3.303, 95% CI: 1.210-9.016, P=.020) was independently associated with 30-day mortality from PE. Inclusion of INR in a model with simplified pulmonary embolism severity index (sPESI) score improved the area under the receiver operating characteristics (ROC) curve from 0.736 (95% CI: 0.659-0.814) to 0.775 (95% CI: 0.701-0.849) (P=.028). Also, the addition of INR to sPESI score enhanced the net reclassification improvement (NRI=8.8%, P<.001) and integrated discrimination improvement (IDI=0.043, P=.027). CONCLUSION: Elevated INR may have prognostic value for 30-day mortality in acute PE patients not on anticoagulation. Combining INR with sPESI score improved the predictive value for all-cause mortality. However, further large-scale studies are needed to confirm it's prognostic role.
