Clinical implication of the Naples prognostic score on transcatheter aortic valve replacement in patients with severe aortic stenosis.

BACKGROUND: One of the hallmarks of frailty in patients with severe aortic stenosis (AS) is malnutrition, for which one of the most up-to-date scoring systems is the Naples prognostic score (NPS). This study sought to investigate the predictive role of the NPS in determining mortality in patients undergoing transcatheter aortic valve replacement (TAVR) under long-term follow-up. METHODS: A total of 430 consecutive patients with symptomatic severe AS who underwent TAVR were included retrospectively. The primary endpoint of the study was the long-term all-cause mortality. The study population was divided into two groups according to the NPS value, including Group 1 (NPS 0-2) and Group 2 (NPS 3-4). RESULTS: The all-cause mortality occurred in 250 patients (62.5%) patients during a follow-up time of 40.6 (22.0-69.4) months. During the follow-up period, all-cause mortality was higher in Group 2 compared with Group 1 (87.9% vs. 42.9%, p < 0.001). Older age (p < 0.001), chronic obstructive pulmonary disease (p = 0.015), left ventricular ejection fraction (p = 0.021), and being in Group 2 (high NPS) (hazard ratio: 7.058, 95% confidence interval: 5.174-9.629, p < 0.001) were found to be independent predictors of all-cause mortality at long-term follow-up. CONCLUSION: The NPS as a malnutrition and inflammation marker in patients with severe aortic stenosis who underwent TAVR provides valuable information for all-cause mortality under long-term follow-up.

A single center study of the efficacy and safety of Pro-Glide used for closure in thoracic endovascular aortic repair in patients with previous groin intervention.

BACKGROUND: This study aimed to evaluate the efficacy and safety of Pro-Glide, a suture-mediated vascular closure device, regarding technical success and complications in patients who had undergone aortic intervention and had previous groin intervention (PGI). METHODS: One hundred and thirty-five patients who underwent percutaneous thoracic endovascular aortic repair via the femoral artery and were closed with the Pro-Glide device were analyzed retrospectively. PGI was defined as a history of open surgical access to the femoral artery or wide sheath (>18 F) placement due to endovascular or valvular intervention. The patients were divided into two groups 38 cases with PGI and 97 cases without PGI. RESULTS: The overall success rate of closure of the femoral artery with Pro-Glide was not statistically significant between the two groups (93.8% vs 92.1%, p = .711). Sheath sizes were compared between the groups and PGI (+) group had significantly higher sheath sizes compared to PGI (-) group (24.3 ± 1.1 F vs 23.8 ± 1.0 F, p = .011). Three patients in the PGI (+) group and six patients in the PGI (-) group experienced technical failure of the percutaneous femoral approach. Femoral complications were seen after the procedures in four patients in the PGI (+) group and four in the PGI (-) group. The PGI (+) group had a higher complication rate when compared to the PGI (-) group; however, this was not statistically significant (p = .181). CONCLUSION: The present study was conducted on a significantly larger sample compared to previous studies and the findings suggest that the Pro-Glide vascular closure device is a safe option for patients with a history of PGI and may not be considered as a contraindication.

The relationship between sarcopenia-related measurements and osteoporosis: The SARCOP study.

As muscle and bone are closely-related, we have explored the association between sarcopenia-related measurements and bone mineral density (BMD) (and osteoporosis) in postmenopausal women. Grip strength, anterior thigh muscle thickness and chair stand test were found to be related with BMD. Additionally, grip strength < 22 kg increased the odds ratio of osteoporosis 1.6 times. INTRODUCTION: As muscle and bone are two closely related tissues, we aimed to investigate the association between sarcopenia-related measurements (i.e., sonographic anterior thigh muscle thickness, grip strength, chair stand test (CST), gait speed) and clinical factors, lumbar/femoral BMD, and the presence of osteoporosis (OP) in postmenopausal women. METHODS: Community dwelling postmenopausal women from two physical and rehabilitation medicine outpatient clinics were consecutively included in this cross-sectional study. Demographic data, age, weight, height, education/exercise status, smoking, and comorbidities were registered. BMD measurements were performed from lumbar vertebrae (L1-4) and femoral neck using dual energy X-ray absorptiometry (DXA). A T-score of ≤ -2.5 SD in the lumbar vertebrae (L1-L4) and/or femoral neck was accepted as OP. Anterior thigh muscle thickness (MT) at the midthigh level was measured sonographically using a linear probe. Grip strength was measured from the dominant side. Physical performance was assessed by CST and gait speed. RESULTS: Among 546 postmenopausal women, 222 (40.7%) had OP. Among sarcopenia-related parameters, grip strength and anterior thigh MT were positively associated with lumbar vertebral BMD. CST performance was positively associated with femoral neck BMD. After adjusting for confounding factors, low grip strength (< 22 kg) increased 1.6 times the risk of OP. CONCLUSION: Loss of muscle mass/function (i.e., sarcopenia) can coexist with loss of trabecular and cortical bone. To this end, grip strength and anterior thigh MT seem to be associated with the lumbar vertebral BMD, while CST is associated with the femoral neck BMD. Lastly, low grip strength might have an association with postmenopausal OP.

Downregulation of TRPM7, TRPM8, and TRPV1 channels modulate apoptotic parameters and neurodegenerative markers: Focus on neuronal differentiation and Parkinson's disease model.

The transient receptor potential channel (TRP) channels are expressed in neuronal tissues and involved in neurological diseases such as pain, epilepsy, neuronal apoptosis, and neurodegenerative diseases. Formerly, we have investigated how neuronal differentiation changes TRP channels expression profile and how Parkinson's disease model is related with this expression levels. We have found that transient receptor potential channel melastatin subtype 7 (TRPM7), transient receptor potential channel melastatin subtype 8 and transient receptor potential channel vanilloid subtype 1 (TRPV1) channels have pivotal effects on differentiation and 1-Methyl-4-phenylpyridinium (MPP+ )-induced Parkinson's disease model in SH-SY5Y cells. In this study, we have investigated that downregulation of the TRP channels to evaluate how differentiation status changes to Parkinson's disease pathological hallmarks. We have also performed to other analyses to elucidate these TRP channels' function in MPP+ -induced neurotoxicity related apoptosis, cell viability, caspase 3 and 9 enzyme activities, intracellular reactive oxygen species production, mitochondrial depolarization levels, Ca2+ signaling, Alpha-synuclein and Dopamine levels, mono amino oxidase A and B enzymatic activities, both in differentiated and undifferentiated neuronal cells. Herein we have concluded that especially TRPM7 and TRPV1 channels have distinct role in Parkinson's disease pathology via their activity changings in pathological state, and downregulation of these channels or specific antagonists can be useful for the possible treatment strategy for Parkinson's disease and related markers.

A Simple Predictor for Long-Term Mortality After Percutaneous Iliac Artery Intervention: Systemic Immune Inflammatory Index.

BACKGROUND: Peripheral arterial disease is a common disease all over the world. Medical treatment, percutaneous invasive treatment, and operation are the considerable options. Percutaneous treatment is a valid option with a higher patency rate. Systemic immune-inflammatory index (SII) is a formula which is calculated as neutrophil count to platelet count divided into lymphocyte count. This formula demonstrates the active inflammatory state. In our study, we aimed to demonstrate the relationship with SII and the mortality, major cardiovascular events, and success rates of percutaneous treatment of iliac artery disease. METHODS: A total of 600 patients underwent percutaneous intervention due to iliac artery disease were enrolled. The primary end point was mortality and the secondary end points were in-hospital thrombosis, restenosis, residual stenosis, and postintervention complications. The best cut-off value of SII to predict mortality was determined and the patients were divided into 2 groups, as those with higher SII values (1,073.782 <) and as those with lower SII values (1,073.782 >). Each group was evaluated in terms of clinical, laboratory, and technical aspects. RESULTS: After exclusion criteria were applied, 417 patients were enrolled into the study. Patients with high SII values had higher rates of in-hospital thrombosis [0 (0%); 3 (2.2%), P = 0.037] and mortality [38 (13.7%); 46 (33.1%), P < 0.001]. In multivariate logistic regression analysis, chronic kidney disease [odds ratio: 4.104, 95 0.5 confidence interval: 2.250-7.487, P < 0.001] and SII [odds ratio: 3.346, 95 0.5 confidence interval: 1.982-5.649, P < 0.001] were found to be independent risk factors for mortality. CONCLUSIONS: SII is a relatively new, simple, and effective mortality risk predictor in patients with iliac artery disease who underwent percutaneous intervention. To the best of our knowledge, our study is the first study which uses SII to predict mortality in such patient group.

A simplified acute kidney injury predictor following endovascular aortic repair: ACEF score.

OBJECTIVES: Treatment of abdominal aortic aneurysms (AAA) with endovascular aortic repair (EVAR) has become quite common in recent years. This method, which has many advantages compared to the open surgical procedure, also has some complications. One of these complications is acute kidney injury (AKI). ACEF (age, creatinine, and ejection fraction) score, which is gaining popularity, can be an easy-to-use and cost-effective method in detecting this condition that causes increased morbidity and mortality. We aimed to evaluate whether this ACEF score may predict a development of AKI in patients who underwent EVAR. METHODS: A total of 133 consecutive patients with AAA who underwent EVAR were analyzed. The primary endpoint of the study was the development of AKI. The best cut-off value for the ACEF score to predict the development of AKI was calculated and according to this value, the patients were divided into two groups as those with high ACEF scores and those with low ACEF scores. ACEF score was calculated by the formula of age/EF + 1 (if baseline creatinine > 2 mg/dL). RESULTS: After the exclusion criteria, a total of 118 patients were included in the study, and 20 (16.9%) of them developed AKI after EVAR. In the ROC curve analysis, a cut-off value of 1.34 was found for the ACEF score, and scores above this value were found to be independent predictors of AKI development after EVAR. In addition to the ACEF score, the contrast media volume was also found to be an independent predictor of the development of AKI. CONCLUSION: In conclusion, ACEF is a simple and effective scoring system in patients undergoing EVAR. To the best our knowledge, our study is the first study which applies ACEF score to predict AKI in EVAR patients.

C-reactive protein to albumin ratio provides important long-term prognostic information in patients undergoing endovascular abdominal aortic repair.

BACKGROUND: The prognostic value of C-reactive protein/albumin ratio (CAR) is of import in cardiovascular diseases. Our aim was to evaluate the impact of the CAR in patients with asymptomatic abdominal aortic aneurysm (AAA) undergoing endovascular aneurysm repair (EVAR). MATERIAL AND METHOD: We retrospectively evaluated 127 consecutive patients who underwent technically successful elective EVAR procedure between December 2014 and September 2020. The optimal CAR cut-off value was determined by using receiver operating characteristic (ROC) curve analysis. Based on the cut-off value, we investigated the association of CAR with long-term all-cause mortality. RESULTS: 32 (25.1%) of the patients experienced all-cause mortality during a mean 32.7 ± 21.7 months' follow-up. In the group with mortality, CAR was significantly higher than in the survivor group (4.63 (2.60-11.88) versus 1.63 (0.72-3.24), p < 0.001). Kaplan-Meier curves showed a higher incidence of all-cause mortality in patients with high CAR compared to patients with low CAR (log-rank test, p < 0.001). Multivariable Cox regression analysis revealed that glucose ≥ 110 mg/dL (HR: 2.740; 95% CI: 1.354-5.542; p = 0.005), creatinine ≥ 0.99 mg/dL (HR: 2.957, 95% CI: 1.282-6.819, p = 0.011) and CAR > 2.05 (HR: 8.190, 95% CI: 1.899-35.320, p = 0.005) were the independent predictors of mortality. CONCLUSION: CAR was associated with a significant increase in postoperative long-term mortality in patients who underwent EVAR. Preoperatively calculated CAR can be used as an important prognostic factor.

Conscious sedation versus general anesthesia for transcatheter aortic valve implantation in patients with severe chronic obstructive pulmonary disease.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is considered a major risk factor for postoperative complications after transcatheter aortic valve implantation (TAVI). To date, there is no clear consensus on the best anesthesia management for these patients. We aimed to investigate the effects of types of anesthesia on clinical outcomes in patients with severe COPD undergoing TAVI. METHODS: This is a single-center, retrospective study comparing conscious sedation (CS) versus general anesthesia (GA) in 72 patients with severe COPD who underwent TAVI. The primary endpoints were 30-day all-cause mortality and postoperative pulmonary complications. RESULTS: The main outcome of interest of this study was that the frequency of pulmonary complications was statistically higher in the GA group (21.4% vs 3.3%, p = 0.038). These differences are most likely attributed to the GA because of prolonged mechanical ventilation, and longer ICU stay (2 (1.2-3) vs 2.5 (2-4) days, p = 0.029) associated with an increased risk of nosocomial infections. There were no significant differences in procedure complications and 30-day mortality between the two groups (GA; 19% vs CS; 13.3%, p = 0.521). One-year survival rates, compared by Kaplan-Meier analysis, were similar between groups (log-rank p = 0.733). CONCLUSION: In aortic stenosis patients with severe COPD undergoing TAVI, the use of GA compared with CS was associated with higher incidences of respiratory-related complications, and longer ICU length of stay. CS is a safe and viable option for these patients and should be considered the favored approach.

A Novel Marker Indicating Restenosis in Superficial Femoral Artery: C Reactive Protein to Albumin Ratio.

BACKGROUND: In this study, we aimed to investigate the prognostic value of C-reactive protein (CRP) to albumin ratio (CAR) for predicting restenosis in superficial femoral artery (SFA) lesions and its association with subsequent clinical outcomes in patients undergoing endovascular intervention. METHODS: The records of 685 consecutive patients who underwent endovascular intervention due to symptomatic peripheral artery disease were analyzed. Patients were divided into 2 groups, based on the CAR values. For each group, technical aspects of procedures and subsequent clinical outcomes were analyzed. RESULTS: According to our study, patients with high CAR values had higher rates of restenosis (30.2% vs. 10.3%, P < 0.05) and mortality (31.3% vs. 12.9%, P < 0.05). The rate of lower extremity amputations was also significantly higher in patients with high CAR values compared to those with low CAR values (9.1% vs. 3%, P < 0.05). With respect to Receiver operating characteristic ROC curves of inflammatory markers, the area under the curve (AUC) value of CAR was statistically significant (AUC: 0.659; 95% confidence interval CI: 0.611-0.706; P < 0.01). CONCLUSIONS: Our data showed that CAR is an independent predictor of restenosis and poor clinical outcomes in patients undergoing endovascular intervention.

Anatomic risk factors for the occurrence of medial talar osteochondral lesions: a case-control study.

OBJECTIVE: This study aimed to determine the anatomical risk factors that may play a role in the etiology of medial-sided osteochondral lesions of the talus (OLT) using morphological parameters in magnetic resonance imaging (MRI). SUBJECTS AND METHODS: One hundred twenty-four patients with medial-sided OLT and age- and sex-matched 124 controls were included in this retrospective study. Two examiners conducted independent OLT classification and measurements of five MRI parameters: tibial axis-medial malleolus angle (TMM), the anterior opening angle of the talus (AOT), talus position (TalPos), the ratio of the distal tibial articular surface to the length of the trochlea tali arc (TAS/TAL), depth of the incisura fibularis (IncDep). Statistical analysis included intraclass correlation coefficients, independent t-tests, receiver-operating characteristic (ROC) analysis, area under the curve (AUC) calculation, and logistic regression analysis. A p-value < 0.05 was considered statistically significant. RESULTS: TTM, AOT, TalPos, and TAL values were significantly higher and the TAS/TAL ratio was significantly lower in the case group than in the control group (p < 0.001). Cut-off and AUC values for TMM were 15.15° (AUC 0.763), AOT 13.05° (AUC 0.826), TalPos 0.75 mm (AUC 0.887), TAL 35.45 mm (AUC 0.642), and TAS/TAL ratio 0.82 (AUC 0.784), p < 0.001. Multivariate logistic regression analysis results were odds ratio (OR) = 6.1 for TMM ≥ 15.15°, OR = 8.9 for AOT ≥ 13.05°, OR = 36.1 for TalPos ≥ 0.75 mm, and OR = 6.7 for TAS/TAL ratio ≤ 0.82. CONCLUSION: Ankle morphology might have an influence on OLT development. The talus position (TalPos) and anterior opening angle of the talus (AOT) seemed to be the strongest predisposing factors.

The effect of complex vascular anatomy on silent new ischemic cerebral lesions in carotid artery stenting procedures (from the COMPLEX-CAS Trial).

BACKGROUND: Carotid artery stenting is a minimally invasive, durable alternative treatment option, which is an alternative to the reference method, carotid endarterectomy, for patients with carotid artery stenosis; however, silent new ischemic cerebral lesions (SNICLs) after carotid artery stenting remain as a matter of concern. Hence, we aimed to assess the effect of complex vascular anatomy on silent new ischemic cerebral lesions in carotid artery stenting procedures. METHODS: We prospectively evaluated 122 patients (mean age: 69.5 ± 7.1 years, male:83) who underwent carotid artery stenting for carotid artery revascularization. The patients having symptomatic transient ischemic attack or stroke after carotid artery stenting were excluded. The presence of a new hyperintense lesions on diffusion-weighted imaging without any neurological findings was considered as the SNICL. Patients were classified into two groups as DWI-positive and DWI-negative patients. RESULTS: Among the study population, 32 patients (26.2%) had SNICLs. The DWI-positive group had a significantly higher common carotid artery (CCA)-internal carotid artery (ICA) angle, older age, more frequent history of stroke, a higher proportion of type III aortic arch, and longer fluoroscopy time than the DWI-negative group. High CCA-ICA angle was identified as one of the independent predictors of SNICL (OR (odds ratio) = 1.103 95%CI (confidence interval): (1.023-1.596); p = 0.034), and CCA-ICA angle higher than 34.5 degrees predicted SNICL with a sensitivity of 62.5% and a specificity of 62.2% (area under the curve: 0.680; 95% CI: 0.570 to 0.789; p = 0.003). CONCLUSIONS: The higher CCA-ICA angle may predict pre-procedure SNICL risk in carotid artery stenting and may have clinical value in the management of patients with carotid artery stenosis.

The predictive value of CHADS2 score for subclinical cerebral ischemia after carotid artery stenting (from the PREVENT-CAS trial).

BACKGROUND: Carotid artery stenting (CAS) is being increasingly used as an alternative revascularization procedure to carotid endarterectomy; however, subclinical ischemic cerebral lesions after CAS remain as a matter of concern. Hence, we aimed to assess the clinical utility of the CHADS2 score in predicting subclinical ischemic events after CAS. METHODS: We prospectively evaluated 107 patients (mean age: 70.4 ± 6.6 years, male:77) who underwent CAS for carotid artery revascularization. The patients having symptomatic transient ischemic attack or stroke after CAS were excluded. The presence of new hyperintense lesion on diffusion-weighted imaging (DWI) without any neurological findings was considered as silent ischemia. Patients were classified into two groups as DWI-positive and DWI-negative patients. RESULTS: Among study population, 28 patients (26.2%) had subclinical embolism. The DWI-positive group had a significantly higher CHADS2 scores, older age, more frequent history of stroke, higher proportion of type III aortic arch, and longer fluoroscopy time than the DWI-negative group. Increased CHADS2 score was identified as one of the independent predictors of silent embolism (OR = 5.584; 95%CI: 1.516-20.566; p = .010), and CHADS2 score higher than 2.5 predicted subclinical cerebral ischemia with a sensitivity of 72% and a specificity of 71% (AUC: 0.793; 95% CI: 0.696 - 0.890; p < .001). CONCLUSIONS: CHADS2 score was able to predict the risk of periprocedural subclinical ischemic events in CAS and might be of clinical value in the management of patients with carotid artery stenosis.

Comparison between PeRcutanEous and surgical femoral aCcess for endovascuLar aOrtic repair in patientS with typE III aortic Dissection (PRECLOSE Trial).

OBJECTIVES: Aortic dissections are cardiovascular events with high mortality and morbidity rates. Management might be either with medical or interventional approach. Recently, thoracic endovascular intervention (TEVAR) becomes the first treatment of choice because of its better results and lower rates of complications in patients with type III aortic dissections. The intervention might be performed via femoral artery either with percutaneous or with surgical approach. Because of large sheath insertion to femoral artery, Pre-close technique is described in literature. The aim of this study was to investigate and compare the outcomes and safety of 'Pre-close technique' to surgical approach in patients with type III aortic dissections who underwent TEVAR with femoral access ≥22 F. METHODS: A total of 96 patients whom had type III aortic dissection and was performed TEVAR were retrospectively included in the study. Fifty-six patients had TEVAR with percutaneous approach and these patients are named as P-TEVAR group, and 40 patients had TEVAR with surgical approach and these patients are named as S-TEVAR group. Pre- and post-procedural data with complications and procedural data during TEVAR were evaluated for both groups and compared in between. RESULTS: The main finding was that there was no significant difference between S-TEVAR and P-TEVAR groups in terms of complications and technical success. Operating room time was significantly decreased in P-TEVAR group (P < 0.001). Overall success rate for femoral approach in patients with Pre-close technique was 94.6% and was 100% for surgical approach. P-TEVAR group had post-operative complications in three patients and S-TEVAR group had in four patients. CONCLUSIONS: Total percutaneous approach with Pre-close technique using Pro-Glide device is a safe and feasible method of femoral access in patients with type III aortic dissections.

Clinical efficacy and safety of the PRO-glide device as a sUture-mediated ClosurE in Thoracic EndoVascular Aortic Repair in patients with previous groin intervention (from the PRODUCE-TEVAR Trial).

BACKGROUND: While the percutaneous approach is increasingly preferred, suture-mediated closure devices have been put into clinical practice to close the femoral artery during procedures requiring a large-sized introducer. However, scar in the groin is considered a contraindication or an exclusion criterion for percutaneous procedures. The aim of our study was to investigate the outcomes and safety of Pro-Glide device as suture-mediated closure device in patients who underwent thoracic endovascular aortic repair with percutaneous femoral access ≥22 F who had previous groin intervention. METHODS: A total of 73 patients who underwent endovascular repair with percutaneous femoral access were retrospectively included in the study. Previous groin intervention was defined as history of open surgical access or large sheath insertion (>18 F) to femoral artery because of endovascular or valvular intervention. Patients were divided into two groups as who had previous groin intervention PGI (+) and had not PGI (-). RESULTS: A total of 73 patients [60 male (82.2%)] were included in the study. Seventeen patients had PGI, and 56 did not. When groups were compared in terms of sheath sizes, a significantly higher sheath sizes were used in PGI (+) patients (24.5 ± 1.1 F vs. 23.8 ± 0.9 F, p = 0.005). The overall success rate in the femoral approach with pre-close technique was statistically insignificant between two groups (94.1% vs. 96.4%, p = 0.55). One patient in PGI (+) group and two patients in PGI (-) had technical failure for percutaneous femoral approach. One patient (5.9%) in PGI (+) group and one patient (1.8%) in PGI (-) group had femoral complications after the procedures; however, there was no significant difference between the groups in terms of complications (5.9% vs. 1.8%, p = 0.13). CONCLUSION: Pro-Glide device may be a safe and less invasive method for femoral access in patients with PGI and might not be considered as a contraindication for patients with history of PGI.

Malnutrition provides important long-term prognostic information in patients undergoing endovascular abdominal aortic aneurysm repair.

OBJECTIVES: Malnutrition has been shown to be associated with survival in a variety of diseases. Our aim is to evaluate the prognostic value of objective nutritional indexes indicating malnutrition, in patients underwent endovascular aortic replacement. METHODS: We retrospectively evaluated 149 consecutive patients who underwent technically successful endovascular aortic replacement operation between October 2010 and August 2019. Objective nutritional indexes, prognostic nutritional index, geriatric nutritional risk index and controlling nutritional status, scores were calculated using the preoperative data. Optimal cut-off values were obtained by receiver operating characteristic analysis. According to the cut-off values, we investigated the relationship between indexes and the long-term all-cause mortality. RESULTS: During mean 48.0 ± 30.3 months follow-up duration, in 47 of patients (31.5%), all-cause mortality were documented. In mortality group, prognostic nutritional index (42.8 ± 7.1 vs 51.3 ± 5.2, p < 0.001) and geriatric nutritional risk index (100.7 ± 10.1 vs 107.6 ± 9.2, p < 0.001) were significantly lower, controlling nutritional status score (2.0 (1.0-4.0) vs 1.0 (0.0-2.0), p < 0.001) was higher when compared to survivor group. Kaplan-Meier curves presented higher mortality incidence in malnutrition patients evaluated with objective nutritional indexes (Log-rang test, for all three indexes p < 0.001). Besides Cox-proportional hazard analysis showed all three nutritional indexes may be a predictive marker for all-cause mortality, prognostic nutritional index introduced more valuable data than other two indexes. CONCLUSIONS: Malnutrition is associated with significant increase in postoperative long-term mortality in endovascular aortic replacement patients. Preoperatively calculated objective nutritional indexes especially prognostic nutritional index can be used as an important prognostic tool.

Utility of logistic clinical SYNTAX score in prediction of in-hospital mortality in ST-elevation myocardial infarction patients undergoing emergent coronary artery bypass graft surgery.

AIM: The logistic clinical SYNTAX score (log CSS) is a combined risk scoring system including clinical and anatomic parameters; it has been found to be effective for the prediction of mortality in patients with ST-elevation myocardial infarction (STEMI). Coronary artery bypass grafting (CABG) in the primary treatment of acute myocardial infarction is still debated. In the present study, we aimed to evaluate the utility of log CSS to stratify the risk of in-hospital mortality in acute STEMI patients undergoing emergent CABG for primary revascularization. METHOD: In total, 88 consecutive patients with acute STEMI, who did not qualify for primary percutaneous coronary intervention and required emergent CABG were included in our study. Nine of 88 patients died during hospitalization. The study population was divided into two groups as in-hospital survivors and non-survivors. Log CSS and SYNTAX score (SS) were calculated for both groups and two groups were compared in terms of demographics, preoperative, intraoperative, postoperative characteristics, SS and log CSS. RESULTS: Log CSS was found to be an independent predictor of in-hospital mortality, log CSS > 10.5 had 89% sensitivity, 81% specificity (area under the curve: 0.927; 95% confidence interval: 0.855-0.993). Moreover, peak troponin level was an independent predictor of in-hospital mortality. Glucose level, cardiopulmonary resuscitation before operation, glomerular filtration rate, left ventricular ejection fraction, and Killip class were significantly associated with in-hospital mortality. CONCLUSION: Log CSS may improve the accuracy of risk assessment in patients who are undergoing emergent CABG for primary revascularization of STEMI.

Prognostic influence of objective nutritional indexes on mortality after surgical aortic valve replacement in elderly patients with severe aortic stenosis (from the nutrition-SAVR trial).

AIM: Several scoring systems, such as controlling nutritional status (CONUT) score, geriatric nutritional risk index (GNRI), and prognostic nutritional index (PNI), have been previously described to show nutritional status. In the present study, we aimed to investigate the value of these scoring systems in predicting in-hospital and long-term mortality in patients undergoing surgical aortic valve replacement (SAVR). METHODS: PNI, GNRI, and CONUT were determined using the receiver operator characteristics curve analysis in 150 consecutive elderly patients (age: 70 (66-74) years, male: 78) who underwent SAVR due to degenerative severe aortic stenosis (AS). Patients were divided into two groups according to cutoff values from these indexes. RESULTS: During the 50 ± 31 months follow-up period, a total of 36 (24%) patients died. 30-day mortality, 1-year mortality, and total mortality were significantly higher in lower PNI, lower GNRI, and higher CONUT groups. PNI cutoff value was 49.2, GNRI cutoff value was 102.5, and CONUT cutoff value was 1.5. PNI ≤ 49.2, GNRI ≤ 102.5, and CONUT > 1.5 values were found to be independent predictors of total mortality even after risk adjustment. In addition, in the mortality group, PNI (53.7 ± 5.9 vs. 47.4 ± 6.3; p < .001) and GNRI (108 ± 10 vs. 99 ± 6.3); p < .001) were significantly lower, while CONUT score (1 [0-2] vs. 2 [0.2-3]; p < .001) was significantly higher. CONCLUSION: Objective nutritional indexes including CONUT score, PNI, and GNRI are important prognostic factors and those indexes should be part of frailty assessment in patients with severe AS.

Detection of a rare cause of pulmonary hypertension by multimodality imaging: Left ventricular endomyocardial fibrosis.

Endomyocardial fibrosis (EMF), a restrictive cardiomyopathy characterized by subendocardial fibrosis, is commonly seen in tropical and subtropical regions. EMF involving the left ventricle presents with severe pulmonary hypertension (PH) and is a rare cause of PH in non-tropical areas. Multimodality imaging is important for accurate diagnosis, especially cardiac magnetic resonance imaging which is the cornerstone. Herein, we report the case of a patient who presented with heart failure symptoms and severe PH, and in whom EMF was diagnosed by multimodality imaging.

Determination of Cerebrovascular Accident Predictors in Patients with New-Onset Atrial Fibrillation After Coronary Artery Bypass Graft Surgery.

BACKGROUND: Postoperative atrial fibrillation (POAF) is associated with an increased risk of short and long-term stroke. Our aim is to identify the independent predictors of cerebrovascular accident (CVA) development in the patients who underwent isolated coronary artery bypass graft (CABG) surgery and developed POAF which lasted within 48 h. METHOD: 301 consecutive patients who underwent isolated CABG surgery in our institution between January 2015 and September 2019 and developed POAF which lasted within 48 h, were retrospectively analyzed. Oral anticoagulant (OAC) treatment was not started in any of these patients, and those who received OAC during follow-ups, were excluded from the study. The predictors of CVA development after mean 32.1± 17.9 months follow-up, were determined by using the Cox proportional hazards model. RESULTS: 20 (6.6%) patients developed CVA, in which 6 (2.0%) of them were in-hospital events. As a result of the multivariate analysis, being over 70 year-old, history of CVA, hypertension (HT), and left ventricular ejection fraction (LVEF) < 45% were determined as the independent predictors of CVA development over time. Having at least two of these factors could predict CVA development with sensitivity of 95.0% and specificity of 82.2%. This predictive value was better than the value obtained with CHA2DS2-VASc score. CONCLUSION: The risk factors which we have obtained, might be used to evaluate the risk of CVA development over time in the patients who underwent isolated CABG surgery and developed POAF which lasted within 48 h.

Evaluation of early electrocardiographic changes after successful percutaneous stent implantation to isolated coarctation of aorta.

BACKGROUND: Coarctation of aorta (CoA) is a congenital obstructive lesion characterized by narrowing of the aorta in which concludes as increase in afterload. Percutaneous stent implantation to CoA is a treatment of choice in older children and adults. Pathology related to CoA mainly caused by increased afterload and left ventricular hypertrophy. Electrocardiographic (ECG) findings are also related to left ventricular hypertrophy (LVH). Evidence shows that, in variety of diseases, the correction of the pathology might normalize ECG findings and ventricular dysfunction related to increase in afterload. Therefore the aim of this study was to compare the pre- and postprocedural ECG findings of the patients who underwent percutaneous intervention for isolated CoA. METHODS: After exclusion criterion was applied, 30 patients were included into study, retrospectively. ECG records before the procedure and 3 months after the procedure of the patients were evaluated. The parameters related to LVH, ventricular and atrial conduction were evaluated and compared between pre- and post-procedural ECG records. RESULTS: The findings showed that parameters of atrial conduction including P wave maximum duration (p < 0.001) and p wave dispersion (p < 0.001) were significantly decreased after stent implantation. Additionally, ventricular repolarization parameters including QT duration (p = 0.039), Tpe interval (p < 0.001), Tpe / QT (p = 0.038) and Tpe / QTc (p = 0.003) were significantly decreased after stent implantation. Sokolow-Lyon criteria (p < 0.003) and voltage in selected leads were significantly decreased after intervention. CONCLUSION: Percutaneous intervention to CoA might regress LVH parameters in ECG and improve atrial and ventricular repolarization in ECG, which might lead to decreased event of atrial and ventricular arrhythmias in patients with isolated CoA.
