Introduction: The systemic immune inflammation index (SII), based on lymphocyte, neutrophil, and platelet counts, has been shown to be an independent indicator of no-reflow phenomenon during percutaneous intervention. However, the relationship between SII and no-reflow phenomenon (NRP) that develops after the procedure of saphenous vein grafts is unknown.

Aim: In this study, we aimed to investigate the relationship between no-reflow phenomenon and SII during percutaneous intervention on saphenous vein grafts.

Vitamin D deficiency is being challenged by the European and global pandemic. Exploring the role of other components in the system of regulation of lipid metabolism, their interrelationships with other systems, without a doubt, building a broader understanding of the pathogenesis of dyslipidemia and promoting new methods of correction and prevention. Impaired lipid metabolism may be accompanied by accumulation of inactive forms of vitamin D due to supra-excess catabolic processes, as well as enzymatic impairment due to a decrease in hydroxylase activity in the liver infiltrated with fat.

Article Synopsis
  • Endovascular treatment for Buerger's disease is complicated, particularly when traditional methods fail; this study examines a new transpedal retrograde approach for patients with ambiguous proximal caps.
  • Eighteen patients who had unsuccessful antegrade interventions were treated, showing significant improvement in limb ischemia severity and wound scores after the retrograde technique.
  • The results suggest that the transpedal retrograde method is a viable and effective option for limb salvage in Buerger's disease, especially when conventional approaches do not work.

Objective: This study aimed to evaluate the effects of statin response on cardiovascular outcomes in patients with ST-segment elevation myocardial infarction.

Methods: A total of 1029 ST-segment elevation myocardial infarction patients were enrolled in the study. The patients who failed to achieve >40% reduction in baseline low-density lipoprotein cholesterol levels within 30 days to 12 months after statin initiation were defined as suboptimal statin responders.

Objective: The systemic immune inflammation (SII) index has been an excellent prognostic indicator in patients with acute ischemic stroke (AIS). In this study, we assessed the utility of the SII in predicting the prognosis and reperfusion status of patients with AIS who underwent endovascular treatment (EVT).

Patients And Methods: 123 consecutive AIS patients were enrolled in our study.

Unlabelled: Metabolic syndrome is of increasing concern globally. The aspects of this disease and its interaction with other morbidities should be discussed in detail. By investigating the effects of metabolic syndrome on the bone fracture rate, we have shown a protective role for metabolic syndrome in the male population.

In this study, we aimed to evaluate the utility of the immune-inflammation index (SII) in estimating the no-reflow phenomenon and short-term cardiovascular prognosis in patients with ST-segment elevation myocardial infarction (STEMI). 723 consecutive patients with STEMI who underwent primary percutaneous coronary intervention (PCI) were enrolled in our study. The receiver-operating characteristics (ROC) curve was used to determine the cut-off value of SII to predict the no-reflow.

: Identification of target organ damage and/or risk-enhancing factors help treatment decisions in hypertensive and hyperlipidaemic patients who reside in borderline to an intermediate risk category based on 10-year atherosclerotic cardiovascular disease (ASCVD) risk estimates.: In the present study, we aimed to investigate the comparative efficacy of certain hypertension-mediated organ damage markers (HMOD) for the prediction of 10-year ASCVD risk ≥10%, in patients with primary hypertension without established CVD.: One-hundred thirty-seven asymptomatic hypertensive patients ≥40 years of age were enrolled in the present study.

Introduction: Direct stenting (DS) is associated with improved markers of reperfusion during primary percutaneous coronary intervention (PPCI) for ST-elevation myocardial infarction (STEMI). However, data evaluating its impact in small vessel coronary artery disease (CAD) are lacking.

Aim: To compare DS and conventional stenting (CS) for small vessel CAD on clinical outcomes of patients with STEMI undergoing PPCI.

Objective: Identification of the asymptomatic target organ damage (AOD) helps to stratify the overall risk of cardiovascular (CV) diseases and guides a treatment decision in hypertensive patients without a symptomatic CV or renal disease. The endothelial-cell-specific molecule 1 (endocan) is regarded as a novel marker of endothelial dysfunction. Its release is increased in hypertensive patients, especially those with symptomatic CV and renal disease.

Introduction: In patients undergoing haemodialysis, cardiovascular mortality and morbidity, characterised by accelerated atherosclerosis and increased inflammation, are elevated. Salusins are newly defined molecules in the atherosclerotic processes, and while salusin-alpha (Sal-α) acts as an antiatherogenic factor, salusin-beta (Sal-β) has a proatherogenic role. Their roles are as yet undefined in patients undergoing haemodialysis.

Background: Atrial fibrillation is one of the most common abnormal heart rhythms. Neutrophil-lymphocyte ratio (NLR) has emerged as a potential marker for the level of inflammation in cardiac disorders.

Hypothesis: NLR might be associated with thrombosis and bleeding risk scores and might predict cardioembolic risk in nonvalvular atrial fibrillation (NVAF) patients within the therapeutic international normalized ratio (INR).

Introduction: Carotid artery stenting (CAS) is a promising alternative to surgery in high-risk patients. However, the impact of stent cell design on outcomes in CAS is a matter of continued debate.

Aim: To compare the periprocedural and clinical outcomes of different stent designs for CAS with distal protection devices.

Aim: This study aimed to evaluate the cardiac autonomic dysfunction and the cardiac arrhythmia risk using heart rate variability parameters in subjects with vitamin D deficiency and low cardiovascular risk.

Material And Methods: One hundred five consecutive individuals, 54 patients with low vitamin D status and 51 healthy controls were enrolled in this study. The overall cardiac autonomic tone was quantified by using various heart rate variability parameters included mean RR interval, mean Heart Rate, mean of standard deviations of intervals for 24 hours (SDNN), standard deviation of averages of intervals (SDANN), mean of standard deviation of intervals for 5 minutes (SDNNI), root mean square of difference of successive intervals (rMSSD) and the proportion of intervals differing more than 50 ms (pNN50) values.

Objective: Left ventricular (LV) rotation and twist play an important role in LV contraction and relaxation. Left bundle branch block (LBBB) deteriorates both diastolic and systolic functions. We evaluated the LV twist in patients with LBBB and preserved ejection fraction (EF) (>50%) to determine twist as a potential marker for subtle myocardial dysfunction.

Time in Therapeutic Range (TTR) is a value used to assess the efficacy of Warfarin treatment. The aim of our study is to determine the effective INR levels and the rate of TTR in patients on Warfarin regimen due to Atrial Fibrillation (AF) or Mechanical Prosthetic Valve (MPV). A total of 94 patients (58 female, and 36 male, mean age: 64.

Background: Carotid artery stenting (CAS) is currently used as an alternative treatment to carotid endarterectomy (CEA). The objective of this study was to analyse our 5-year experience performing CAS. Secondarily, we sought to determine independent risk factors which predict periprocedural complications.

Carotid artery stenosis (CAS) is primarily caused by atherosclerotic plaque. Progressive inflammation may contribute to the rupture of an atherosclerotic plaque. The platelet-to-lymphocyte ratio (PLR) is a new and simple marker that indicates inflammation.

Introduction: Pulse transit time (PTT) is the duration that a pulse wave takes to travel between two different arterial points, and it may be useful in estimating blood pressure. The aim of this study was to investigate the PTT during carotid artery stenting, as well as its value in blood pressure estimation.

Method: Thirty-four patients with critical carotid artery stenosis were enrolled in this study.
