Study on 295 consecutive medical patients to evaluate the potential of routine blood tests to identify the risk of deep vein thrombosis (DVT). The tests included in a DVT risk stratification model system were erythrocyte sedimentation rate, antithrombin III, C-reactive protein, D-dimer, and N-terminal pro-brain natriuretic peptide. The DVT risk stratification system was moderately prognostic (area under the curve: 0.838; 95% confidence interval: 0.771-0.904; P < .001), whereas its performance was as follows-sensitivity, 100%; specificity, 20%; positive predictive value, 21%; and negative predictive value, 100%...

Cardiovascular (CV) disease (CVD) is a leading cause of morbidity and mortality worldwide. Most CV events are caused by atherosclerosis. Diabetes and impaired glucose tolerance are associated with greater carotid intima-media thickness (IMT) and increased risk for CVD. The present study examined if common carotid artery IMT (CCAIMT) is predictive of CVD irrespective of glucose tolerance category and glycated hemoglobin (HbA1c) in a sample of 639 women with different glucose tolerance categories. During 7-year follow-up, 30 events in the cardiac and 32 events in the cerebral territory were documented...

Acute kidney injury (AKI) is a recognized complication post-endovascular aneurysm repair (EVAR). Neutrophil gelatin-associated lipocalin (NGAL), interleukin 18 (IL-18), and retinol-binding protein are emerging urinary biomarkers that have shown promise in detecting subclinical and clinical renal impairment. In this study, we assessed changes in these urinary biomarkers as well as serum creatinine (SCr) in patients undergoing EVAR. Urine samples were collected prospectively at 5 time points for each recruited patient: pre-EVAR (baseline) and 6, 12, 24, and 48 hours after the procedure for serial assessment of urinary biomarkers...

Contrast-induced nephropathy (CIN) is a common complication of coronary angiography/percutaneous coronary intervention (PCI). Identification of high-risk patients and optimal periprocedural management are key points to reduce the incidence of this iatrogenic complication. We evaluated the impact of gender on CIN after coronary angiography/PCI. We enrolled 2851 consecutive patients (730 females and 1851 males) undergoing coronary angiography/PCI. Baseline clinical and procedural characteristics were collected according to gender...

Carotid artery atherosclerosis (CAA) represents a significant form of atherosclerosis with stroke as a major consequence. Whether it is a unique form of atherosclerosis is not established. However, this is not of major clinical relevance as no specific preventive measures over and above the established ones for cardiovascular risk are well established. Major risk factors for CAA are elevated low-density lipoprotein cholesterol (LDL-C), diabetes mellitus, tobacco use, hypertension, and increased inflammation...

Carotid artery stenting (CAS) is increasingly offered to patients with carotid artery stenosis. Although CAS is a less invasive (and thus more attractive) alternative compared with carotid endarterectomy, it requires the use of contrast material. A possible side effect from the use of contrast material during CAS is the development of contrast-induced acute kidney injury (CI-AKI). This review discusses the incidence/prevalence and clinical significance of CI-AKI developing after CAS. We also discuss possible measures to reduce the incidence of CI-AKI after CAS...

INTRODUCTION: This study aimed to evaluate the efficacy and safety of limus-based drug-eluting stent (DES) implanted in medium or small coronary vessels during a very long-term follow-up period. METHODS: A total of 2383 patients treated with 2916 limus-based DES between April 2003 and March 2015 were evaluated. The enrolled patients were stratified into 3 groups according to the reference vessel diameter: group A: ≤2.5 mm; group B: 2.51 to 3.00 mm; group C: 3...

Intermediate-risk pulmonary embolism (PE), also known as submassive PE, occurs in a substantial group of patients and carries a significant mortality risk. With adequate risk stratification, catheter-directed techniques could be used as a therapeutic approach in the intermediate-risk PE. Ultrasound-assisted catheter-directed thrombolysis (UCDT) represents a novel endovascular technique with good clinical and safety outcomes. Ultrasound-assisted catheter-directed thrombolysis can achieve reduction in the thrombus burden and improvement of pulmonary hemodynamics and right ventricular (RV) dysfunction and/or dilatation, without major procedure-related complications, major bleeding, or hemorrhagic strokes...

Obstructive sleep apnea (OSA) has been suggested as a risk factor for carotid atherosclerosis. The present meta-analysis aimed to evaluate the association between OSA and carotid intima-media thickness (CIMT). Eighteen studies comparing CIMT of patients with OSA versus non-OSA patients were included. Quantitative data synthesis was used to pool weighted standardized difference in means (SMD) of CIMT in a random-effects model. Compared to healthy controls, patients with OSA had a significantly higher CIMT (SMD: 0...

The metabolic syndrome (MetS) is a cluster of risk factors for cardiovascular disease. The aim of this study is to determine the influence of MetS on short- and long-term outcome and survival after carotid endarterectomy (CEA). Between January 2005 and December 2014, data from all patients undergoing CEA were prospectively recorded. The metabolic syndrome was defined based on the presence of ≥3 of the following criteria: hypertension, high serum triglycerides, low levels of high-density lipoprotein cholesterol, high fasting serum glucose, and obesity...

The differences in angiographic characteristics and cardiovascular (CV) risk factors between coronary artery aneurysm (CAA) and coronary artery ectasia (CAE) have not been compared systematically. Of 10 876 patients undergoing coronary angiography, patients with CAA (n = 85) and CAE (n = 51) were screened. The prevalence of CAA was greater than that of CAE (P < .05). The right coronary artery was the most involved (70.6%) in CAE compared with left circumflex (52.9%) and left anterior descending (41.2%). Coronary artery aneurysm coexisted with coronary artery disease (CAD) more frequently than CAE (P = ...

The anoxemia theory proposes that an imbalance between the demand for and supply of oxygen in the arterial wall is a key factor in the development of atherosclerosis. There is now substantial evidence that there are regions within the atherosclerotic plaque in which profound hypoxia exists; this may fundamentally change the function, metabolism, and responses of many of the cell types found within the developing plaque and whether the plaque will evolve into a stable or unstable phenotype. Hypoxia is characterized in molecular terms by the stabilization of hypoxia-inducible factor (HIF) 1α, a subunit of the heterodimeric nuclear transcriptional factor HIF-1 and a master regulator of oxygen homeostasis...
