RESUMO

BACKGROUND: We aimed to investigate the prognostic value of serum albumin-to-creatinine ratio (sACR) in carotid artery stenting (CAS) patients regarding in-hospital and 5-year outcomes. METHODS: This is a retrospective study. Baseline characteristics were compared between patients by admission albumin to creatinine ratio and categorized accordingly: T1, T2 and T3. 609 patients were included in the study. Serum albumin and creatinine levels at hospital admission were used to calculate the sACR. The primary endpoint was all-cause mortality. MACE consisted of stroke, transient ischemic attack (TIA), myocardial infarction (MI) and death. All follow-up data were obtained from electronic medical records or by interview. The study was terminated after 60 months of follow-up. RESULTS: Serum albumin levels were found to be significantly lower in T1, while creatinine was found to be significantly higher in T1. T1 has the lowest sACR while T3 has the highest. In hospital, ipsilateral stroke, major stroke, MI and death were significantly higher in T1. In long-term outcomes, ipsilateral stroke, major stroke, and death were significantly higher in T1. CONCLUSIONS: Low sACR values at hospital admission was independently associated with in-hospital and long-term mortality and major stroke in patients underwent CAS.

RESUMO

Atrial fibrillation (AF) is one of the most encountered arrhythmias in clinical practice. It is also estimated that the absolute AF burden may increase by greater than 60% by 2050. It is inevitable that AF will become one of the largest epidemics in the world and may pose a major health problem for countries. Although AF rarely causes mortality in the acute period, it causes a significant increase in mortality and morbidity, including a fivefold increase in the risk of stroke, a twofold increase in dementia, and a twofold increase in myocardial infarction in the chronic period. Despite all the advances in the treatment of AF, it is better understood day by day that preventing AF may play a key role in reducing AF and its related complications. Modification of the main modifiable factors such as quitting smoking, abstaining from alcohol, changing eating habits, and exercise seems to be the first step in preventing AF. The strict adherence to the treatment process of secondary causes predisposing to AF such as DM, hypertension, obesity, and sleep apnea is another step in the prevention of AF. Both an individual approach and global public health campaigns can be highly beneficial to reduce the risk of AF. In this review, we aimed to summarize the current evidence on the relationship between modifiable risk factors and AF, and the impact of possible interventions on these factors in preventing or reducing the AF burden in the light of recently published guidelines and studies.

RESUMO

Patients with recent myocardial infarction (MI) or percutaneous coronary interventions (PCI) have a higher ischemic risk in addition to perioperative bleeding risk when undergoing coronary artery bypass grafting (CABG). Data regarding preoperative dual antiplatelet therapy (DAPT) failed to create a clear recommendation. In the present study, we assessed the relationship between preoperative DAPT use and adverse outcomes, particularly in ST-elevation MI (STEMI) patients. We retrospectively analyzed 748 consecutive patients with STEMI who underwent subsequent CABG surgery. Patients were divided into 2 groups: those on DAPT up to the day before CABG and those discontinued DAPT >5 days before CABG. Predictors of in-hospital mortality and major bleeding were analyzed by multivariate analysis. Preoperative DAPT was not associated with in-hospital mortality (Odds Ratio (OR):1.81; 95% Confidence Interval (CI): .89-3.68, P = .10) and major bleeding (OR: 1.15; 95% CI: .63-2.08, P = .65) after multivariate analysis. However, glycoprotein (Gp) 2b/3a inhibitors were independently associated with higher major bleeding rates. Age, shock, and EF (ejection fraction) <30% were associated with in-hospital mortality. Previous MI, Gp 2b/3a inhibitors, and EF <30% were predictors of major bleeding. In conclusion, there were no association between pre-CABG DAPT use and in-hospital mortality and major bleeding.

RESUMO

There is minimal information available regarding the early effects of bronchial asthma (BA) and its treatment on cardiac function in children. We used two-dimensional speckle-tracking echocardiography (2D-STE) to evaluate cardiac function before and after the treatment of childhood BA. We enrolled 44 children with moderate and severe BA who had not been treated over the preceding 3 months or who were newly diagnosed. All children received the same treatment (that recommended by the Global Initiative for Asthma [GINA] in 2017). All children also underwent transthoracic 2D-STE before treatment and 6 months later. Clinical data were compared before and after treatment. After treatment, significant increases were evident in right ventricular (RV) systolic and diastolic strain, as well as the systolic strain rate. Before and after treatment, the RV global longitudinal systolic strains were - 22.8 ± 3.6 and - 25.1 ± 4.5, respectively (p = 0.036); the RV global longitudinal diastolic strains were - 18.5 ± 6.0 and - 21.5 ± 5.2, respectively (p = 0.038); and the RV systolic strain rates were - 1.26 ± 0.4 and - 1.12 ± 0.3, respectively (p = 0.025). After treatment, significant increases were observed in the right atrial (RA) peak longitudinal strain and strain rate. Before and after treatment, the RA peak atrial longitudinal strains were 32.5 ± 10.8 and 44.7 ± 11.2, respectively (p = 0.042) and the RA longitudinal strain rates were - 1.6 ± 0.3 and - 2.0 ± 0.5, respectively (p = 0.041). RV and RA subclinical dysfunction may develop in children with early-stage BA. However, asthma treatment appears to improve such dysfunction. In children with BA, clinical and subclinical changes in cardiac functions can be easily detected via 2D-STE.

RESUMO

INTRODUCTION: Pregnancy is a process that can cause several physiologic changes to the cardiovascular system such as ventricular hypertrophy and dilation of cardiac chambers. Although there are studies about pregnancy-related changes in echocardiographic examination; there is no data about the long-term effects of parity on these alterations. Therefore, we evaluated the long-term effect of pregnancy on right ventricular (RV) dilation and RV hypertrophy and their relation to the parity number. METHODS: This prospective study included a total of 600 women (200 consecutive women who had no parity, 200 women who had a parity number of 1 to 4 and 200 women who had a parity number of more than 4). Right chambers' measurements were compared between the groups. RESULTS: In echocardiographic analysis, RV and right atrial dimensions and areas and RV wall thickness were higher in parous women. On the other hand, RV systolic function parameters were significantly lower in parous women. These significant changes showed a gradual increase or decrease by increasing parity number. By multivariate hierarchical logistic regression analysis, the four independent factors that increased the risk of RV dilation were age (OR: 1.16 CI: 1.10-1.20), body mass index (OR: 1.05, CI: 1.02-1.08), smoking (OR: 1.87, CI: 1.28-4.02), and giving a birth (OR: 3.94 CI: 1.82-8.81). There was also independent relationship between the number of parity and RV hypertrophy even after adjustment for several confounders. CONCLUSION: Pregnancy-related physiological changes mostly resolve after delivery. This study about long-term effects of pregnancy on RV has demonstrated that there is a significant relation between the number of parity and either RV dilation or RV hypertrophy. Each parity had also additive effect on these changes.

RESUMO

OBJECTIVE: This study examines the predictive value of the novel systemic immune-inflammation index (SII) in patients with ST-segment elevation myocardial infarction (STEMI). METHODS: A total of 1660 patients with STEMI who underwent primary percutaneous coronary intervention (pPCI) were enrolled in the study. In-hospital and 3-year outcomes were compared between the four groups (Q1-4). The SII was calculated using the following formula: neutrophil*platelet/lymphocyte. RESULTS: The frequency of in-hospital cardiogenic shock, acute respiratory failure, acute kidney injury, ventricular arrhythmia, stent thrombosis, recurrent myocardial infarction, major adverse cardiac events and mortality were significantly higher in the high SII groups (Q3 and Q4). Logistic regression models demonstrated that Q3 and Q4 had an independent risk of mortality and Q4 had an independent risk of cardiogenic shock compared to Q1. Receiver operating characteristic analysis showed that the best cutoff value of SII to predict the in-hospital mortality was 1781 with 66% sensitivity and 74% specificity. Kaplan-Meier overall survivals for Q1, Q2, Q3 and Q4 were 97.6, 96.9, 91.6 and 81.0%, respectively. Cox proportional analysis for 3-year mortality demonstrated that Q3 and Q4 had an independent risk for mortality compared to Q1. CONCLUSION: SII, a novel inflammatory index, was found to be a better predictor for in-hospital and long-term outcomes than traditional risk factors in patients with STEMI undergoing pPCI.

RESUMO

BACKGROUND: According to clinical practice guidelines, thrombolysis can be administered during the 14 days after the beginning of symptoms in PE. However, the role of the early thrombolysis in PE has not been comprehensively investigated. In this study we evaluated the effect of short symptom-to-thrombolysis time (STT) in these patients who received the thrombolytic therapy within the 48-h. METHOD: A total of 456 patients with pulmonary embolism who underwent thrombolytic therapy in a tertiary center were included in the current study. The patients were stratified into three groups according to STT as: <12 h (Group 1), 12 to 24 h (Group 2) and > 24 to 48 h (Group 3). In-hospital events and long-term mortality were compared between the groups. RESULTS: Group 3 had higher in-hospital mortality, acute kidney injury, cardiogenic shock, asystole, and the use mechanical ventilation and 3-year mortality compared to the other two groups. The 3-year overall survival for Group 1, 2 and 3 were 82.1%, 77.7% and 25.9% respectively. According to regression analysis, a STT > 24 h was independently associated with in-hospital and long-term mortality. Group 1 and 2 had similar in-hospital outcomes and long-term mortality. CONCLUSION: A short STT has a great importance in patients with PE who treated with thrombolytic therapy. The efficacy of systemic thrombolysis significantly drops after 24 h. Because of this situation, the period between the symptom onset and thrombolytic therapy should be kept short as much as possible.

RESUMO

OBJECTIVE: To assess coronary artery calcification (CAC) in patients with acute pulmonary embolism and determine whether this correlates with right ventricular dilation (RVD) and mortality. METHODS: Computed tomography pulmonary angiography scans of 330 patients were used to perform retrospective assessment of the pulmonary artery computed tomography obstruction index (PACTOI), the right/left ventricle diameter ratio, the diameter of the pulmonary trunk, and the ordinal CAC score. RESULTS: Age (P < 0.001), urea level (P < 0.001), D-dimer level (P = 0.006), diameter of the pulmonary trunk (P < 0.001), and PACTOI (P < 0.001) were significantly higher in the RVD-positive patient group. We found a significant relation between increased CAC score and increased mortality (P = 0.038). Left-sided CAC was detected much more often in RVD-positive patients (P = 0.008). CONCLUSIONS: Coronary artery calcification is common in patients with acute pulmonary embolism, especially when those patients are also RVD-positive. A significant relation was found between RVD and left-sided CAC.

RESUMO

BACKGROUND: Inflammatory mechanisms play an important role in both atherosclerosis and stroke. There are several inflammatory peripheral blood count markers associated with carotid artery stenosis degree, symptomatic carotid artery lesions and carotid artery stent restenosis that reported in previous studies. However, the prognostic role of the blood cell counts and their ratios in predicting in-hospital and long-term outcomes in patients undergoing carotid artery stenting (CAS) has not been comprehensively investigated. Systemic immune-inflammation index (SII) proved its' efficiency in patients with solid tumors and its' role was rarely examined in cardiovascular disorders and stroke. The current study evaluated the effect of this novel risk index on in-hospital and long-term outcomes in a large patient population who underwent CAS. METHOD: A total of 732 patients with carotid artery stenosis who underwent CAS were enrolled to the study. SII was calculated using the following formula: neutrophil-to-lymphocyte ratio × total platelet count in the peripheral blood (per mm3) and the patients were stratified accordingly: T1, T2 and T3. In-hospital and 5-year outcomes were compared between the tertiles of SII. RESULTS: During the hospitalization, major stroke, ipsilateral stoke, myocardial infarction, death and major adverse cardiovascular events (MACE) rates were significantly higher in high SII level (T3) compared to SII levels (T1 and 2). In long-term outcomes, ipsilateral stroke, major stroke, transient ischemic attack, death, and MACE were significantly higher in the patients with higher SII level (T3). The 5-year Kaplan-Meier overall survival for T1, T2, and T3 were 97.5%, 96.7% and 86.0% respectively. In-hospital and 5-year regression analyses demonstrated that high SII was independently associated with MACE and mortality. CONCLUSION: SII was independently associated with in-hospital and long-term clinical outcomes in patients undergoing CAS. Immune and inflammation status, as assessed easily and quickly using SII, has a good discriminative value in these patients.

RESUMO

Introduction: The objective of the present research was to evaluate the possible association between the N-terminal pro-brain type natriuretic peptide (NT-proBNP) levels and in-hospital mortality in coronavirus disease 2019 (COVID-19) pneumonia patients who did not have pre-existing heart failure (HF). Methods: A total of 137 consecutive patients without pre-existing HF and hospitalized due to COVID-19 pneumonia were enrolled into the current research. The main outcome of the research was the in-hospital death. The independent parameters linked with the in-hospital death were determined by multivariable analysis. Results: A total of 26 deaths with an in-hospital mortality rate of 18.9% was noted. Those who died were older with an increased frequency of co-morbidities such as hypertension, chronic kidney disease, coronary artery disease, stroke and dementia. They had also increased white blood cell (WBC) counts and had elevated glucose, creatinine, troponin I, and NT-pro-BNP levels but had decreased levels of hemoglobin. By multivariable analysis; age, NT-pro-BNP, WBC, troponin I, and creatinine levels were independently linked with the in-hospital mortality. After ROC evaluation, the ideal value of the NT-pro-BNP to predict the in-hospital mortality was found as 260 ng/L reflecting a sensitivity of 82% and a specificity of 93% (AUC:0.86; 95%CI:0.76-0.97). Conclusion: The current research clearly shows that the NT-proBNP levels are independently linked with the in-hospital mortality rates in subjects with COVID-19 pneumonia and without HF. Thus, we believe that this biomarker can be used as a valuable prognostic parameter in such cases.

RESUMO

This study evaluated the impact of the baseline estimated glomerular filtration rate (eGFR) on clinical and angiographic outcomes and long-term in-stent restenosis (ISR) rates in patients undergoing elective carotid artery stenting (CAS) procedures. Consecutive patients who underwent CAS were retrospectively enrolled (n = 456). At the end of 3 years of follow-up, patients who had died or were lost follow-up were excluded from the study and a final analysis was performed using data from the remaining 405 patients. The study population (n = 405) was divided into 3 tertiles based on the tertile values of the eGFR level (T1, T2, and T3); then, clinical and procedural characteristics and 3-year ISR rates were compared between the groups. An ISR of 50% was detected in 49 (12%) surviving patients. The 3-year ISR was higher among patients with the lowest eGFR values (T1) by 3.7 times (95% CI: 2.01-11.38) than that among patients with the highest eGFR values (T3). These significant relationships persisted following adjustment for confounders. A lower baseline eGFR level was significantly associated with an increased ISR rate. Decreased renal function may be a predictor of ISR after CAS using first-generation stents.

RESUMO

OBJECTIVES: Contrast-induced acute kidney injury (CI-AKI) is a life-threatening complication that leads to comorbidities and prolonged hospital stay lengths in the setting of peripheral interventions. The presence of some CI-AKI risk factors has already been investigated. In this study, we evaluated the predictors of CI-AKI after carotid artery stenting. METHODS: A total of 389 patients with 50% to 99% carotid artery stenosis who underwent carotid artery stenting were included in this study. Patients were grouped according to CI-AKI status. RESULTS: CI-AKI developed in 26 (6.6%) patients. Age, baseline creatinine level, neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio were higher and estimated glomerular filtration rate, haemoglobin and lymphocyte count were lower in CI-AKI patients. In the multivariate regression analysis, the neutrophil-to-lymphocyte ratio triggered a 1.39- to 2.63-fold increase in the risk of CI-AKI onset (p < 0.001). CONCLUSIONS: The neutrophil-to-lymphocyte ratio may be a significant predictor of CI-AKI in patients with carotid artery stenting and higher neutrophil-to-lymphocyte ratio values may be independently associated with CI-AKI.

RESUMO

OBJECTIVE: The present study aimed to compare the value of D-dimer measured on the 3rd day of hospitalization with admission D-dimer level in predicting in-hospital mortality in coronavirus disease 2019 (COVID-19) cases. METHOD: In total, 231 patients with COVID-19 disease were included in the study. D-dimer levels were estimated using immunoturbidimetric assay with normal range of 0-500 µg/mL. In the current research, the primary outcome was the in-hospital mortality. RESULTS: In the present research, 39 (16.8%) COVID-19 cases died during the index hospitalization. In a multivariable analysis; age, D-dimer (3rd day) (OR: 1.00, 95% CI: 1.00-1.00, p<0.001), WBC count, and creatinine were independent predictors of the in-hospital death for COVID-19 cases. The ideal value of D-dimer level on the 3rd day of hospitalization was 774 µq/mL (area under curve (AUC): 0.903, 95% CI: 0.836-0.968; p<0.01) with sensitivity of 83.2% and specificity of 83.6%. It was noted that D-dimer level on the 3rd day of hospitalization had a higher sensitivity (83.2% vs 67.6%, respectively) and AUC value than that of D-dimer level on admission (0.903 vs 0.799, respectively). CONCLUSION: The main finding in this investigation was that D-dimer elevation on the 3rd of hospitalization is more sensitive predictor of in-hospital mortality than D-dimer elevation on admission in COVID-19 patients. Even though further investigations are needed to forecast precise prognosis in patients with COVID-19 disease in terms of D-dimer levels, we believe that D-dimer levels on the 3rd day of hospitalization have an enhanced potential to be used as a prognostic marker in routine clinical practice.

RESUMO

Decision of ad hoc revascularization strategy in patients who require coronary artery bypass grafting (CABG) following primary percutaneous coronary interventions (PCI) is challenging due to the pros and cons of only-ballooning and stenting. In this study, we aimed to compare the outcomes of only-balloon-angioplasty to stenting in primary PCI in patients with ST elevated myocardial infarction (STEMI) who required a subsequent CABG. We retrospectively analyzed 350 consecutive STEMI patients who needed CABG in addition to primary balloon angioplasty (n = 160) and stenting strategy (n = 190). In-hospital and 5-year outcomes of the patients were compared between the 2 groups. In-hospital mortality rates in the ballooning and stenting groups were not nonsignificantly different (11.2% vs 9.5%, respectively, P = .59); 5-year mortality rates were also similar between the 2 groups (9.2% vs 8.7%, P = .89). Additionally, major bleeding rates (3.8% vs 6.3%, P = .28) did not differ between the 2 groups. In conclusion, our study showed no significant difference in-hospital and long-term mortality rates in patients who require CABG after primary PCI irrespective of the ad hoc revascularization strategy.

RESUMO

BACKGROUND: Although aortic valve replacement (AVR) when successfully performed boasts low mortality rates in selected patients, prosthesis-patient mismatch (PPM) can be found in the majority of these individuals. Limited research is available supporting the benefit of two-dimensional speckle tracking echocardiography (2D-STE) in patients with severe PPM. This study sought to assess myocardial strain using 2D-STE to determine the relationship between subclinical left ventricular (LV) dysfunction and aortic PPM in patients undergoing AVR with preserved LV ejection fraction. MATERIAL AND METHODS: We retrospectively examined all consecutive patients with isolated AVR who presented to our center from 2005 to 2018. The data of 1086 patients were analyzed. Severe PPM was defined as an indexed effective orifice area of 0.65 cm2/m2 or less. As a result of the detailed assessment, 54 patients meeting the eligibility criteria were included in the study. Baseline data were collected and compared between the two groups of patients with severe PPM (n = 27) and those with normofunctional aortic prosthesis valve as a control group (n = 27). All patients underwent baseline echocardiography. Global longitudinal strain (GLS) and global circumferential strain (GCS) were evaluated by 2D-STE. RESULTS: When compared with controls, patients with severe PPM had significantly decreased GLS (18.6 ± 2.9 vs. 21.4 ± 2.1; p < 0.01) and GCS (17.2 ± 3.6 vs. 21.7 ± 2.1; p < 0.01) values. CONCLUSION: In addition to standard clinical and echocardiographic parameters, GLS and GCS suggest subclinical dysfunction and have incremental value in patients with severe PPM.

RESUMO

This research analyses the re-organization of a blood supply chain organization. Blood supply chain network design is a hard problem. Uncertainties of the blood supply and demand, perishability of blood over time and compatibility of blood types are some factors that make the problem difficult. This paper presents a novel multi-objective mixed-integer location-allocation model for a blood supply chain design problem. Unlike many studies on blood supply chain design in the literature, supply chain network consisting of mobile and permanent units is planned together effectively with our mixed-integer programming model. Multi-objective structure of the model minimizes distances between the blood supply chain elements and the length of the mobile unit routes. The objectives are prioritized by experts using the Analytical Hierarchical Process. Finally, the model is implemented on a real life case study using real data from the Eastern Anatolia region of Turkey for various supply demand scenarios. The solutions offered by the model are compared with the current situation in the region. It is shown that the proposed model gives at least %25 more effective solutions. Moreover, sensitivity analysis on the budget constraint is conducted, and robustness of the model is empirically illustrated.

RESUMO

It has been reported that myocardial damage and heart failure are more common in COVID-19 patients with severe symptoms. The aim of our study was to measure the right ventricular functions of COVID-19 patients 30 days after their discharge, and compare them to the right ventricular functions of healthy volunteers. Fifty one patients with COVID-19 and 32 healthy volunteers who underwent echocardiographic examinations were enrolled in our study. 29 patients were treated for severe and 22 patients were treated for moderate COVID-19 pneumonia. The study was conducted prospectively, in a single center, between 15 May 2020 and 15 July 2020. We analyzed the right ventricular functions of the patients using conventional techniques and two-dimensional speckle-tracking. Right ventricular end-diastolic and end-systolic area were statistically higher than control group. The right ventricular fractional area change (RVFAC) was significantly lesser in the patient group compared to the control group. Tricuspid annular plane systolic motion (TAPSE) was within normal limits in both groups, it was lower in the patient group compared to the control group. Pulmonary artery pressure was found to be significantly higher in the patient group. Right ventricular global longitudinal strain (RV-GLS) was lesser than the control group (- 15.7 [(- 12.6)-(- 18.7)] vs. - 18.1 [(- 14.8)-(- 21)]; p 0.011). Right ventricular free wall strain (RV-FWS) was lesser in the patient group compared to the control group (- 16 [(- 12.7)-(- 19)] vs - 21.6 [(- 17)-(- 25.3)]; p < 0.001). We found subclinical right ventricular dysfunction in the echocardiographies of COVID-19 patients although there were no risk factors.

RESUMO

Intravenous leiomyomatosis (IVL) is a rare and benign smooth muscle tumor that arises from intrauterine venules or the myometrium. We herein describe a 49-year-old woman with a history of myomectomy who developed abdominal pain. An intravascular mass with extension to the right atrium was detected in the inferior vena cava. The mass was surgically resected in a single stage under cardiopulmonary bypass. IVL features were indicated by subsequent histopathology. Postoperatively, the patient was diagnosed with massive pericardial effusion and treated with a pericardial window. At 3 months' outpatient clinical follow-up, she was asymptomatic. This case indicates that the diagnosis of IVL with extension to the heart should be kept in mind in patients presenting with abdominal pain.

RESUMO

The CHA2DS2-VASc score predicts stroke and mortality risk in several cardiovascular diseases regardless of atrial fibrillation. In this study, we aimed to investigate the ability of CHA2DS2-VASc score to predict in-hospital and long-term outcomes in patients undergoing carotid artery stenting (CAS). The study population included 558 patients undergoing CAS. The patients were stratified into three groups based on their CHA2DS2-VASc scores [low (≤ 2, n = 123), moderate (3-5, n = 355) and high (6-8, n = 80)]. In-hospital and 3-year outcomes were compared between the groups. In-hospital rates of ipsilateral and major strokes and death were significantly different between the groups (1.6% vs. 3.9% vs. 16.2%; 1.6% vs. 4.5% vs. 16.2%; 0.8% vs. 3.1% vs. 13.8%, p < 0.001 for all, respectively). At 3 years of follow-up, rates of ipsilateral and major strokes and death were significantly increased in patients with highscore compared to those with moderate and low scores (1.6% vs. 5.8% vs. 13%, p = 0.005; 0.8% vs. 5.2% vs. 13%, p = 0.001; 1.6% vs. 8.4% vs. 15.9%; p = 0.002, respectively). After adjusting for multi-model Cox regression analysis, CHA2DS2-VASc score persisted as an independent prognostic factor for mortality and major stroke in patients undergoing CAS. Higher CHA2DS2-VASc score predicted increased risk of in-hospital and 3- year stroke and mortality in patients undergoing CAS.
