BACKGROUND AND AIMS: There is strong evidence that fat accumulating in non-adipose sites, "ectopic fat", is associated with cardiovascular disease (CVD), including vascular calcification. Most previous studies of this association have assessed only a single ectopic fat depot. Therefore, our aim was to assess the association of total, regional, and ectopic fat with abdominal aorto-illiac calcification (AAC) and coronary artery calcification (CAC) in 798 African ancestry men. METHODS: Participants (mean age 62) were from the Tobago Bone Health Study cohort...

BACKGROUND AND AIMS: Despite advances in the treatment of peripheral artery disease (PAD), cardiovascular events and death rates remain high. This study aimed at identifying markers of outcome in patients with PAD undergoing endovascular therapy (EVT). METHODS: Consecutive patients undergoing EVT were recruited. Markers of oxidative stress (malondialdehyde-modified low-density lipoprotein [MDA-LDL]), inflammation (IL-6; high-sensitivity C-reactive protein [hsCRP]) and fibrinolysis (D-dimer) were measured pre-EVT and at post-EVT time-points to 36 h...

INTRODUCTION: Adipose tissues secrete adipokines, peptides with potent effects modulating fibrosis, inflammation, and vascular homeostasis. Dysregulated adipose tissue biology and adipokine balance have been recently implicated in systemic sclerosis (SSc). We sought to determine if altered circulating adipokine levels correlate with SSc disease subsets or clinical manifestations. MATERIALS AND METHODS: Multiplex assays were used to measure circulating adipokine levels in 198 patients with SSc and 33 healthy controls...

BACKGROUND: Kawasaki disease (KD) is an acute febrile systemic vasculitis that disturbs coronary arteries. Patients' risks of adverse cardiovascular events and subclinical atherosclerosis have been found to significantly increase with polymorphisms of the human cytochrome P450. This current study aims to research the possible relationship between Cytochrome P450, Family 2, Subfamily E, and Polypeptide 1 (CYP2E1) polymorphisms with KD. METHODS: We selected six tag single-nucleotide polymorphisms (tSNPs) of the CYP2E1 gene for TaqMan allelic discrimination assay in 340 KD patients and performed analysis on the clinical phenotypes and coronary artery lesions (CAL)...

Sacral neuromodulation (SNM) is an effective therapy for patients who experience urinary incontinence, idiopathic urinary retention, and fecal incontinence. Although typically a low-risk procedure, rarely, it can be associated with significant hemorrhage. A 61-year-old woman on chronic anticoagulation underwent uncomplicated implantation of SNM for refractory urgency urinary incontinence. Anticoagulation was held on the day of surgery and resumed on postoperative day 1. On postoperative day 2, the patient developed an extensive retroperitoneal hemorrhage...

BACKGROUND: Recent observations have suggested a decline in vulnerable carotid artery and iliofemoral atherosclerotic plaque characteristics over the past decade. The aim of this study was to determine whether, in the presence of clinically manifest carotid or peripheral artery disease, secondary adverse cardiovascular events decreased over this period. METHODS: Patients included in the Athero-Express biobank between 2003 and 2012 were analysed. During 3-year follow-up, composite cardiovascular endpoints were documented yearly, including: myocardial infarction, coronary interventions, stroke, peripheral interventions and cardiovascular death...

Objective Sinus tachycardia is frequently reported in systemic lupus erythematosus (SLE), while there are limited data on post-exercise ability to slow heart rate (i.e. heart rate recovery, HRR) in this group of patients. Methods We studied consecutive 70 patients with SLE and 30 healthy controls. All examined individuals underwent detailed clinical examination, echocardiography, Holter monitoring with heart rate variability and treadmill stress test using Bruce's protocol. HRR values were calculated as the difference between maximum HR during exercise and HR at the first (HRR1) and third (HRR3) minute of rest...

The accuracy of color Doppler ultrasonography (CDU) is hampered by the presence of arterial wall calcifications. B-flow imaging may overcome these limitations. We present a case of a severely calcified stenosis of the right common femoral artery (CFA) diagnosed with the aid of B-flow imaging. Both the CT angiography scan and CDU were limited by the presence of diffuse dense arterial calcifications. B-flow imaging showed a >75% stenosis of the CFA. B-flow imaging appears to improve the accuracy of CDU in the presence of calcified stenosis of the CFA...

BACKGROUND Superficial femoral artery chronic total occlusion (SCTO) is a common type of peripheral arterial disease (PAD). Endovascular therapy is a treatment approach that has a poor long-term success rate in this group. The aim of this study was to compare the mid-term results of two different uses of nitinol stents in long SCTO lesions (>100 mm): the use of one long stent or two shorter stents. MATERIAL AND METHODS Of 154 patients who underwent percutaneous infrainguinal interventions from 2011 to 2014, a total of 170 CTO lesions were selected for this retrospective study analysis...
