Hematological predictors of silent new cerebral ischemic lesions in carotid artery stenting: A retrospective study.

BACKGROUND: Silent new cerebral ischemic lesions (sNCIL) are a common complication of carotid artery stenting (CAS) that can lead to an increase in morbidity and mortality. We aimed to evaluate the impact of hematological parameters on sNCIL in patients undergoing CAS. METHODS: We retrospectively evaluated 103 patients who underwent CAS, with a mean age of 70.5 ± 6.7 years, and 31 (20.1 %) of whom were female. Stents were placed for internal carotid artery revascularization. The presence of new hyperintense lesions on diffusion-weighted imaging (DWI) without neurological symptoms was considered as sNCIL in cases without apparent neurological findings. Patients were categorized into two groups based on DWI results: positive (29) and negative (74). RESULTS: In the study population, sNCIL was observed in 29 patients (28.2 %). The DWI-positive group exhibited significantly higher Plateletcrit (PCT) levels, advanced age, and a lack of embolic protection device usage compared to the DWI-negative group. The Receiver Operating Characteristic (ROC) analysis identified a PCT value of 0.26 as the optimal threshold, detecting the development of sNCIL with a sensitivity of 75.9 % and specificity of 59.1 % (AUC: 0.700; 95 % CI: 0.594-0.806, p = 0.002). CONCLUSION: To be determined by a simple blood parameter, PCT can predict the risk of sNCIL before CAS and holds clinical value in the treatment of patients with carotid artery stenosis.

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 hyperpolypharmacy and one-year outcomes in patients with critical limb ischemia undergoing below-knee endovascular therapy.

BACKGROUND: Critical limb ischemia (CLI) patients take too many medications because they are elderly and frail patients with multiple comorbidities. Polypharmacy is associated with frailty, although its prognostic significance in CLI patients is unknown. In this study, we aimed to determine the prevalence of hyperpolypharmacy among adults with CLI and its effect on 1-year amputation and mortality. METHODS: A total of 200 patients with CLI who underwent endovascular therapy (EVT) for below-knee (CTC) lesions were included in this study. Hyperpolypharmacy was defined as using ≥10 drugs. Patients were divided into two groups according to the presence of hyperpolypharmacy. RESULTS: We detected hyperpolypharmacy in 66 patients. The incidence of 1-year amputation [24 (36.4) versus 12 (9), p<.001] and mortality [28 (42.4) versus 12 (9), p<.001] were higher in patients with hyperpolypharmacy. Univariate and multivariate cox regression analyses were used to determine the independent predictors of amputation and mortality. In the receiver operating characteristic curve analysis, the cut-off value was defined as 10 or more drug use was able to detect the presence of 1-year mortality with 67.5% sensitivity and 79.4% specificity. The Kaplan-Meier method showed a significant difference (rank p <.001 between log groups), and hyperpolypharmacy was associated with 1-year amputation and mortality. CONCLUSION: Hyperpolypharmacy was significantly associated with 1-year mortality and major amputation in CLI patients. Hyperpolypharmacy can be a valuable aid in patient risk assessment in the CLI.

Fragmented QRS complex may predict long-term mortality after isolated surgical aortic valve replacement in patients with severe aortic stenosis.

OBJECTIVES: Fragmented QRS (fQRS), related to myocardial fibrosis, is an important prognostic marker of cardiovascular events and mortality. Aortic stenosis (AS), the most frequent valvular heart disease in developed countries, causes myocardial fibrosis due to ventricular pressure overload. The current study aimed to investigate whether fQRS is associated with long-term mortality after isolated surgical aortic valve replacement (SAVR) in patients with severe AS. METHODS: A total of 289 patients who underwent SAVR for severe AS between May 2009 and January 2020 with interpretable electrocardiogram were included. Patients were divided into 2 groups according to the presence of fQRS. Kaplan-Meier survival analyses were used to detect cumulative survival rates. Univariable and multivariable Cox proportional hazards models were used to determine the predictors of all-cause mortality. RESULTS: fQRS occurred in 126 (43.5%) patients. A total of 59 (20.4%) patients died over a follow-up period of 54 ± 32 months. All-cause mortality was higher in the fQRS group (23 [14.1%] vs 36 [28.6], log-rank test P = 0.002) in the long term. The presence of fQRS [hazard ratio (HR): 1.802, confidence interval (CI): 1.035-3.135, P = 0.037], electrocardiographic left ventricular strain (HR: 1.836, CI: 1.036-3.254, P = 0.038) and history of stroke or transient ischaemic attack (HR: 3.130, CI: 1.528-6.412, P = 0.002) were independent predictors of all-cause mortality in the multivariable Cox regression model. CONCLUSIONS: fQRS is associated with a 1.8-fold increase in long-term mortality in patients undergoing isolated SAVR for severe AS. Detecting fQRS in electrocardiograms may provide prognostic information about the long-term outcomes.
