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.

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

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.
Predictors of In-Hospital Mortality in Patients With ST-Segment Elevation Myocardial Infarction Complicated With Cardiogenic Shock
(2019) Hayiroglu, Mert Ilker; Keskin, Muhammed; Uzun, Ahmet Ozkan; Yildirim, Duygu Ilke; Kaya, Adnan; Cinier, Goksel; Bozbeyoglu, Emrah; Yildirimturk, Ozlem; Kozan, Omer; Pehlivanoglu, Seckin; 29191504
Background ST-segment elevation myocardial infarction (STEMI) complicated with cardiogenic shock (CS) remains as an unresolved condition causing high morbidity and mortality despite advances in medical treatment and coronary intervention procedures. In the current study, we evaluated the predictors of in-hospital mortality of STEMI complicated with CS. Methods In this retrospective study, we evaluated the predictive value of baseline characteristics, angiographic, echocardiographic and laboratory parameters on in-hospital mortality of 319 patients with STEMI complicated with CS who were treated with primary percutaneous coronary intervention. Patients were divided into two groups consisting of survivors and non-survivors during their index hospitalisation period. Results The mortality rate was found to be 61.3% in the study population. At multivariate analysis after adjustment for the parameters detected in univariate analysis, chronic renal failure, Thrombolysis In Myocardial Infarction (TIMI) post percutaneous coronary intervention (PCI) <= 2, plasma glucose and lactate level, blood urea nitrogen level, Tricuspid Annular Plane Systolic Excursion (TAPSE) and ejection fraction were independent predictors of in-hospital mortality. Conclusions Apart from haemodynamic deterioration, angiographic, echocardiographic and laboratory parameters have an impact on in-hospital mortality in patients with STEMI complicated with CS.
