Relationship between platelet mass index and postoperative atrial fibrillation after elective coronary artery bypass surgery: a retrospective study.

BACKGROUND: Atrial fibrillation (AF) is the most common complication after cardiac surgery. The pathogenesis of postoperative atrial fibrillation (POAF) is multifactorial and one of the known factors is inflammation. Platelet mass index (PMI) is an indicator of platelet activation and a better inflammatory marker than mean platelet volume (MPV). In this retrospective study, we investigated the relationship between POAF and PMI. METHODS: The study included 848 consecutive patients (655 male and 193 female) who had elective isolated coronary artery by-pass grafting (CABG) or combined CABG and valvular surgery. Platelet count and MPV were measured from preoperative blood samples to calculate PMI. Post-operative atrial fibrillation was defined as irregular and fibrillatory P waves occurring 48-96 h after cardiac surgery and lasting at least 30 s. The PMI values in patients who developed POAF were compared with those in patients who did not develop POAF. RESULTS: Patients who developed POAF had higher PMI values (2549.3 ± 1077.1) when compared with patients in sinus rhythm (2248.1 ± 683.4; p < 0.01). In multivariate regression analysis, age (OR: 1.05; 95% CI: 1.02-1.09; p = 0.01), left atrial diameter (OR: 1.05; 95% CI: 1.03-1.09; p = 0.02), hs-CRP (OR: 1.09; 95%CI: 1.05-1.13; p < 0.01), EuroSCORE II (OR: 1.27; 95% CI: 1.14-1.41; p < 0.01), and PMI (OR: 1.01; 95% CI: 1.001-1.02; p < 0.01) were independent predictors of POAF. In ROC analysis, PMI ≥ 2286 predicted POAF development with a sensitivity of 69% and a specificity of 58% (AUC: 0.66; p < 0.01) CONCLUSION: A significant relationship was found between preoperatively calculated PMI and POAF. We showed that PMI may be used to predict patients who are at high risk of developing POAF.

Association of Uric Acid Albumin Ratio with Recurrence of Atrial Fibrillation after Cryoballoon Catheter Ablation.

Objective: Despite improvements in the technology of catheter ablation of atrial fibrillation (AF), recurrences are still a major problem, even after a successful procedure. The uric acid/albumin ratio (UAR), which is an inexpensive and simple laboratory parameter, has recently been introduced in the literature as a predictor of adverse cardiovascular events. Hence, we aimed to investigate the relationship between the UAR and AF recurrence after catheter ablation. Methods: A total of 170 patients who underwent successful catheter ablation for AF were included. The primary outcome was the late recurrence after treatment. The recurrence (+) and recurrence (−) groups were compared for clinical, laboratory and procedural characteristics as well as the predictors of recurrence assessed by regression analysis. Results: In our study population, 53 (26%) patients developed AF recurrence after catheter ablation. Mean UAR was higher in the recurrence (+) group compared to recurrence (−) group (2.4 ± 0.9 vs. 1.8 ± 0.7, p < 0.01). In multivariable regression analysis, left atrial diameter (HR: 1.08, 95% CI: 1.01−1.16, p = 0.01) and UAR (HR:1.36, 95% CI: 1.06−1.75, p = 0.01) were found to be independent predictors of recurrence. In ROC analysis, the UAR > 1.67 predicted recurrence with a sensitivity of 77% and a specificity of 57% (AUC 0.68, p < 0.01). Conclusion: For the first time in the literature, the UAR were found to be correlated independently with AF recurrence after catheter ablation.

Endocarditis-TR: Diagnosis, treatment, and prognosis of the infective endocarditis patients admitting tertiary centres of Turkey.

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.

Prognostic Significance of Controlling Nutritional Status Score (CONUT) in Patients Undergoing Pericardiocentesis.

BACKGROUND: Malnutrition is associated with a poor prognosis in cardiovascular diseases, however the prognostic impact of the Controlling Nutritional Status (CONUT) score in patients with pericardial effusion (PE) is not known. METHODS: This was a retrospective study conducted among 301 consecutive patients with PE who underwent pericardiocentesis. CONUT score was calculated from serum albumin level, total cholesterol level and lymphocyte count. The prognostic role of admission CONUT score on long-term mortality was evaluated. RESULTS: The patients were divided into two groups according to long-term mortality. A total of 131 patients died during follow-up. In multivariable regression analysis, chronic heart failure [hazard ratio (HR): 3.21, 95% confidence interval (CI): 1.18-8.70, p < 0.01], malignancy (HR: 5.67, 95% CI: 3.34-9.63, p < 0.01) and CONUT score (HR: 1.21, 95% CI: 1.10-1.33, p < 0.01) were found to be independent predictors of long-term mortality. CONUT score was significantly higher in the patients who died (5.8 ± 2.4 vs. 3.6 ± 2.2, p < 0.01). In receiver operating characteristics analysis, a CONUT score ≥ 4.5 predicted long-term mortality with 66% sensitivity and 69% specificity (area under curve: 0.73, 95% CI: 0.67-0.79, p < 0.01). CONCLUSIONS: In patients with PE, CONUT score is an independent prognostic factor for mortality.

Modified SAMe-TT2R2 score for predicting the therapeutic range of digoxin.

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 >1.2 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, p < 0.01), white blood cell count (OR: 1.12, 95% CI: 1.01-1.27, p < 0.01), and the modified SAMe-TT2R2 score (OR: 4.19 95% CI: 3.71-4.72, p < 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, p < 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.

Prognostic value of serum uric acid levels in patients with non-STEMI undergoing percutaneous coronary intervention.

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.

Risk factors and outcomes in patients with ectatic infarct-related artery who underwent primary percutaneous coronary intervention after ST elevated myocardial infarction.

OBJECTIVE: We aimed to assess the risk factors for coronary artery ectasia (CAE) as infarct-related artery (IRA) and short-term and 1 year outcomes. BACKGROUNDS: CAE in patients with ST elevated myocardial infarction (STEMI) is a rare condition with a limited knowledge about the risk factors associated with coronary artery ectasia in STEMI and prognosis after primary percutaneous coronary interventions. METHODS: Retrospectively, 1655 patients with STEMI who were undergone coronary angiography were included in this study. Patients were divided into two groups according to their coronary anatomy as ectasia and control groups. Demographic features, angiographic results, and clinical events were compared. Multivariate analysis was performed to assess the association of the features with CAE in STEMI. RESULTS: In total, 1655 patients (99 patients in CAE group vs 1556 patients in control group) were analyzed. Hypertension and smoking were significantly higher in CAE group. No-reflow rates were significantly higher (13.1% vs 5.4%, p = 0.004) in CAE group. In-hospital mortality rates were similar between the groups. Difference in revascularization rates (8.1% vs 9.6%, p = 0.39) and death in 1 year (6.1% vs 4.9%, p = 0.37) were also nonsignificant between the groups. According to results of the multivariate analysis, hypertension (Odds ratio (OR): 1.71 (1.14-2.58), p = 0.01) and smoking (OR: 1.98 (1.32-2.99), p = 0.001) remained significantly associated with coronary ectasia. CONCLUSION: In conclusion, despite being higher no-reflow rates, short-term and 1 year survival and revascularization rates were similar between the groups. Additionally, hypertension and smoking were associated with CAE as IRA. © 2016 Wiley Periodicals, Inc.

Prognostic Value of QRS Fragmentation in Patients with Acute Myocardial Infarction: A Meta-Analysis.

AIMS: Fragmented QRS has emerged as a novel electrocardiographic parameter associated with adverse clinical events in various diseases. The aim of this study was to investigate the association of fQRS with in-hospital and long-term cardiovascular events in patients with ST-segment elevation myocardial infarction (STEMI) and non-ST segment elevation myocardial infarction (NSTEMI). METHODS AND RESULTS: We searched PubMed, Embase, Web of Science, and Cochrane Library up to October 2015 for eligible studies. We selected studies with fQRS defined with 12-lead ECG during the index hospitalization of STEMI/NSTEMI. Primary outcomes were in-hospital and long-term cardiovascular events. In-hospital mortality was significantly higher in fQRS (+) group (99/733; 13.5%) compared to fQRS (-) group (47/1293; 3.6%) (OR 4.03 95% CI 1.81-8.94; P = 0.0006). Long-term mortality rate was higher in fQRS (+) group (89/473; 18.8%) compared to fQRS (-) group (54/1009; 5.3%) (OR 3.93 95% CI 1.92-8.05; P = 0.0002). In addition the frequency of long-term MACE was higher in fQRS (+) group (46.9%) compared to fQRS (-) group (14.6%) (OR 5.13 95% CI 2.77-9.51; P < 0.00001) CONCLUSION: Presence of fQRS on admission ECG was found to be predictor of mortality, MACE, deterioration of LV function, and presence of multivessel disease in patients with STEMI and NSTEMI.

Monocyte to high-density lipoprotein ratio as a new prognostic marker in patients with STEMI undergoing primary percutaneous coronary intervention.

BACKGROUND: Monocyte count to high-density lipoprotein ratio (MHR) has recently emerged as an indicator of inflammation and oxidative stress in the literature. We aimed to investigate the prognostic value of MHR in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention (PCI). METHODS: A total of 513 patients who were hospitalized with diagnosis of acute ST-segment elevation myocardial infarction and treated with primary PCI were retrospectively enrolled in the study. Demographic and clinical data, admission laboratory parameters, and MHR values were recorded. Inhospital major adverse cardiac events (MACE) and mortality were reported as the clinical outcomes. RESULTS: Twenty-six patients (5%) died, and MACE was observed in 86 patients (17%) during hospital follow-up. Patients were categorized in 3 groups according to tertiles of admission MHR. The rates of inhospital mortality and MACE were significantly higher in tertile 3 group compared to tertile 1 group (10% vs 1%, 27% vs 11%; P < .01 and P < .01). In multivariate regression analysis, age, sex, presence of Killip 3 or 4, left ventricular ejection fraction, troponin I, C-reactive protein, and increased MHR levels (odds ratio, 1.03; 95% confidence interval, 1.01-1.05; P < .01) independently predicted inhospital mortality; age, presence of Killip 3 or 4, troponin I, and increased MHR levels (odds ratio, 1.02; 95% confidence interval, 1.01-1.04; P < .01) independently predicted MACE. CONCLUSION: Admission MHR values were found to be independently correlated with inhospital MACE and mortality after primary PCI.

Association of contrast-induced nephropathy with bare metal stent restenosis in STEMI patients treated with primary PCI.

BACKGROUND: Contrast induced nephropathy (CIN) has been proven as a clinical condition related to adverse cardiovascular outcomes. However, relationship between CIN and stent restenosis (SR) remains unclear. In this study, we aimed to investigate the association of CIN with SR rates after primary percutaneous coronary intervention (PCI) and bare metal stent (BMS) implantation. METHODS: A total number of 3225 patients who had undergone primary PCI for STEMI were retrospectively recruited. The medical reports of subjects were searched to find whether the patients had a control coronary angiogram (CAG) and 587 patients with control CAG were included in the study. The laboratory parameters of 587 patients were recorded and patients who developed CIN after primary PCI were defined. Contrast induced nephropathy was defined as either a 25% increase in serum creatinine from baseline or 0.5 mg/dL increase in absolute value, within 72 h of intravenous contrast administration. RESULTS: The duration between primary PCI and control CAG was median 12 months [8-24 months]. The rate of SR was significantly higher in CIN (+) group compared to CIN (-) group (64% vs. 46%, p < 0.01). In multivariate Cox regression analysis, male gender, stent length, admission WBC levels and presence of CIN (HR 1.39, 95% CI 1.06-1.82, p < 0.01) remained as the independent predictors of SR in the study population. CONCLUSION: Gender, stent length, higher serum WBC levels and presence of CIN are independently correlated with SR in STEMI patients treated with BMS implantation.

Association of Serum Cholesterol Levels with Short-term Mortality in Patients with Acute Pulmonary Embolism.

BACKGROUND: Serum cholesterols play an important role in pathophysiology and prognosis of acute thrombotic diseases. The aim of the present study was to investigate the prognostic value of serum lipid parameters in acute pulmonary embolism (APE). METHODS: From January 2008 to January 2014 a total of 275 patients who were hospitalised with a diagnosis of APE were retrospectively screened. Clinical data, laboratory parameters, serum cholesterol levels were recorded and pulmonary embolism severity index (PESI) scores were calculated. Mortality rate at 30 days was investigated as the clinical outcome. RESULTS: In our study population, 24 patients (8.7%) died within 30 days. Serum total cholesterol, LDL-C, HDL-C and triglyceride levels were significantly lower in deceased patients when compared to the survived patients (3.1 ± 0.6 vs. 4.7 ± 1.2 mmol/L, p < 0.01; 1.8 ± 0.9 vs. 2.9 ± 0.9 mmol/L, p < 0.01; 0.9 ± 0.3 vs. 1.2 ± 0.3 mmol/L, p < 0.01; 1.4 ± 0.7 vs. 1.7 ± 0.6 mmol/L, p = 0.04, respectively). In multivariate regression analysis; PESI scores (OR: 1.06 95% CI: 1.01-1.11, p < 0.01), right ventricular diameter (OR: 11.31 95% CI: 3.25-52.64, p < 0.01), total cholesterol (OR: 1.09 95% CI: 1.02-1.17, p < 0.01), LDL-C (OR: 1.06 95% CI: 1.01-1.12, p = 0.02), HDL-C (OR: 1.21 95% CI: 1.04-1.41, p < 0.01) and triglyceride (OR: 1.03 95% CI: 1.01-1.05, p < 0.01) levels were independently correlated with mortality. CONCLUSIONS: Serum total cholesterol, LDL-C, HDL-C and triglyceride levels, obtained within the first 24hours of hospital admission, may have prognostic value in patients with APE.

Assessment of Prognostic Value of Neutrophil to Lymphocyte Ratio and Platelet to Lymphocyte Ratio in Patients with Pulmonary Embolism.

BACKGROUND: Acute pulmonary embolism is a serious medical condition that has a substantial global impact. Inflammation plays a role in the pathophysiology and prognosis of acute pulmonary embolism (APE). The aim of the present study was to investigate the prognostic value of admission parameters for complete blood count (CBC) in APE. METHODS: A total of 203 patients who were hospitalized with diagnosed APE were retrospectively enrolled in the study. Clinical data, PESI scores, admission CBC parameters, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were all recorded. The clinical outcomes of study subjects were determined by the reported patient 30-day mortality and long-term mortality. RESULTS: During a median follow-up period of 20 months [interquantile range 17], 34 subjects in the study population (17%) died. NLR and PLR levels were significantly higher in patients who died within the 30 days (n = 14) [9.9 (5.5) vs. 4.5 (4.1), p = 0.01 and 280 (74) vs. 135 (75), p = 0.01, respectively] and during the long-term follow-up (n = 20) [8.4 (2.9) vs. 4.1 (3.8), p = 0.01 and 153 (117) vs. 133 (73), p = 0.03, respectively] when compared to the patients that survived. In Cox regression analysis, age, systolic blood pressure, systolic pulmonary arterial pressure, PESI scores (HR 1.02 95%CI 1.01-1.04, p = 0.01), elevated levels of NLR (HR 1.13 95%CI 1.04-1.23, p = 0.01) and PLR (HR 1.002 95%CI 1.001-1.004, p = 0.01) were independently correlated with total mortality. CONCLUSIONS: Admission NLR and PLR may have prognostic value in patients with APE.

Relationship between Neutrophil-to-Lymphocyte Ratio and Left Ventricular Free Wall Rupture in Acute Myocardial Infarction.

OBJECTIVES: This study aimed to evaluate the relationship between the neutrophil-to-lymphocyte (N/L) ratio and left ventricular free wall rupture (LVFWR) in patients with ST elevation myocardial infarction (STEMI). Previous studies showed a correlation between increased levels of inflammatory markers and adverse cardiovascular events. The role of inflammation markers, particularly the N/L ratio, in mechanical complications after myocardial infarction has not been studied. METHODS: Retrospectively, we compared the N/L ratio values of 23 patients with STEMI complicated by LVFWR with 214 STEMI patients without this complication. The diagnosis of rupture was confirmed by echocardiography in each case. RESULTS: Neutrophil counts [median 8.5 × 103/µl, interquartile range (IQR) 6.4, vs. 7.8 × 103/µl, IQR 4.7, p = 0.02] and the N/L ratio (5.66, IQR 4.17, vs. 4.1, IQR 3.93, p = 0.01) were significantly higher in the LVFWR group. In receiver operating characteristic analysis, an N/L ratio above 3.7 predicted LVFWR with a sensitivity of 82.6% and a specificity of 46.9% (area under the curve = 0.654, p = 0.016). In multivariate regression analysis, age, hypertension, increased creatinine levels and increased N/L ratio (odds ratio = 1.61, 95% confidence interval = 1.15-2.23, p = 0.01) were found to be independent predictors of LVFWR. CONCLUSIONS: In our study, the N/L ratio was found to be independently correlated with the risk of LVFWR. © 2015 S. Karger AG, Basel.

Effectiveness and safety of thrombolytic therapy in elderly patients with pulmonary embolism.

Pulmonary embolism (PE) is a major cause of cardiovascular death. Thrombolytic therapy was shown to reduce mortality, especially in high risk patients. In elderly patients (>65 years old) with PE, thrombolytic therapy may be underused due to risk of hemorrhagic complications. In this study, we aimed to assess the effectiveness and safety of thrombolytic therapy among elderly patients with PE. 363 patients (205 subjects in study group, 158 subjects in control group) who were admitted to our hospital with PE were enrolled to the study. The patients were divided into subgroups according to their age and treatment strategy. Mortality rates and bleeding complications according to TIMI bleeding criteria in 30 days and 1-year were analyzed. In elderly patients, total mortality (7.8 vs. 20.1 %, p = 0.05) and mortality at 1-year follow-up (1.9 vs. 12.9 %, p = 0.03) was significantly lower in patients who received thrombolytic treatment. Difference in total bleeding (9.8 vs. 4.5 %, p = 0.18) and major bleeding (3.9 vs. 0.6 %, p = 0.10) in thrombolytic and non-thrombolytic groups was non-significant. Thrombolytic therapy is associated with lower mortality and acceptable bleeding complication rates in PE patients older than 65 years old.

Assessment of electrocardiographic parameters in patients with electrocution injury.

BACKGROUND: Electrocution injury (EI) is a major problem in developing countries. The aim of this study is to investigate the effect of EI on electrocardiographic (ECG) parameters. METHODS: A total of 43 patients hospitalized with diagnosis of EI were prospectively enrolled. Admission ECGs were compared with follow-up ECGs obtained one month after the event. RESULTS: Maximum P wave duration (Pmax), minimum P wave duration (Pmin), P wave dispersion (PWD), PR interval, QRS complex duration, corrected QT duration (QTc), QT dispersion (QTD), T peak to T end (Tp-e) interval were longer and Tp-e interval/QT and Tp-e interval/QTc ratios were higher on admission ECGs compared to follow-up ECGs. Frontal QRS-T angle and frequency of patients with fragmented QRS were also higher on admission ECGs. CONCLUSION: Our study revealed that EI causes significant deterioration of admission ECG parameters. The clinical use of these parameters in prediction of arrhythmias after EI warrants further studies.

Increased Serum CRP-Albumin Ratio is Independently Associated With In-Stent Restenosis After Carotid Artery Stenting.

Atherosclerotic stenosis of the carotid artery contributes significantly to ischemic strokes. This study investigates the correlation between the C-reactive protein (CRP) to albumin ratio (CAR) and in-stent restenosis (ISR) in patients (n = 529) undergoing carotid artery stenting. Patients were categorized based on ISR occurrence. Cox regression analyses were performed to identify independent predictors of ISR. The ISR rate was 10.3%. Laboratory analysis revealed higher levels of uric acid, CRP, and CAR in the ISR group. Cox regression identified CAR as an independent predictor of ISR (Hazard ratio (HR): 1.13, 95% CI: 1.03-1.24, P = .01), along with diabetes and smoking. A CAR cut-off of 0.28 predicted ISR with 93% sensitivity and 89% specificity (Area under the curve (AUC): 0.945, 95% CI: 0.923-0.963, P < .001). This study establishes a significant association between CAR and ISR in carotid artery stenting patients. The inflammatory response, indicated by CAR, emerges as a crucial factor in ISR development. The study contributes valuable insights into predicting and preventing ISR, emphasizing the potential of CAR as a prognostic biomarker. This easily accessible and cost-effective biomarker could enhance ISR prediction and guide preventive strategies for high-risk patients.

Prognostic performance of Controlling Nutritional Status score in patients with ST segment elevation myocardial infarction treated with primary percutaneous coronary intervention.

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.

A novel electrocardiographic parameter for the prediction of atrial fibrillation after coronary artery bypass graft surgery "P wave peak time".

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).

Thrombolytic Therapy in Octogenarians with Acute Pulmonary Embolism. / Terapia Trombolítica em Octogenários com Embolia Pulmonar Aguda.

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.
