More than half of deaths in end-stage kidney disease (ESKD) patients are due to cardiovascular disease. Elevated fibroblast growth factor 23 (FGF-23) was found to be associated with mortality in hemodialysis (HD) patients and correlates with peripheral calcification. Aortic calcification is associated with coronary artery calcification. Both aortic and peripheral vascular calcifications were associated with mortality in chronic kidney disease. We aimed to investigate the relation between intact FGF-23 and cardiovascular calcification in patients with ESKD who were maintained on regular HD...

In this substudy of the ADAPT-DES trial Généreux et al. compared two years outcomes according to the presence or absence of coronary artery calcification (CAC) as assessed by coronary angiography. Coronary calcification was an independent predictor of interventional treatment failure and a higher incidence of both ischemic events and bleeding. The cohort with CAC was older with a higher prevalence of risk factors and comorbidities and an increased anatomical complexity of the target lesions, explaining only in part the worse outcome of the CAC population that persisted at multivariate analysis...

OBJECTIVES: We evaluated the clinical outcomes of patients with chronic kidney disease (CKD) who underwent orbital atherectomy for severe coronary artery calcification (CAC) prior to stent implantation. BACKGROUND: Percutaneous coronary intervention (PCI) of lesions with severe CAC is associated with increased rates of adverse clinical events. Patients with CKD are at increased risk for atherosclerotic cardiovascular disease, including vascular calcification, and have worse outcomes after PCI...

A 68-year-old female with acute coronary syndrome was transferred to our hospital. Emergency coronary angiography showed 90% stenosis with severe calcification in the proximal right coronary artery (RCA). Intravascular ultrasound (IVUS) images were obtained and showed circumferential heavy calcification without any evidence of plaque rupture. Optical frequency domain imaging (OFDI) images were obtained in the RCA lesion 3 days after the initial coronary angiography. A cavity of plaque rupture in the calcified plaque by using OFDI was observed in the lesion, which could not be recognized by IVUS...

Patients with chronic kidney disease (CKD) have an increased risk of vascular disease, which is associated with considerable health care costs. Vascular disease in CKD differs clinically and pathobiologically from that in patients with normal renal function. Besides the traditional risk factors, retention of uremic toxins contributes to the pathogenesis of vascular disease in patients with CKD. Indoxyl sulfate is a protein-bound uremic toxin and is inefficiently removed by conventional dialysis. Accumulating evidence suggests that indoxyl sulfate is a vascular toxin involved in atherosclerosis, arteriosclerosis, vascular calcification and vascular repair...

Orbital atherectomy has been developed as a method to modify calcified plaque in the peripheral vasculature, with extensive experience and data supporting its use in infrainguinal peripheral arterial disease. However, calcific atherosclerotic disease occurs in other vascular beds and may benefit from the application of this technology. In this case report, we describe the first reported use of orbital atherectomy in a renal artery. A 55-year-old male with severe drug-refractory hypertension was found to have renal artery stenosis, with severe calcification of the right renal artery...

BACKGROUND: Preliminary data suggests the absence of coronary artery calcification (CAC) excludes ischemic etiologies of cardiomyopathy. We prospectively validate and perform a systematic review to determine the utility of an Agatston score=0 to exclude the diagnosis of ischemic cardiomyopathy. METHODS AND RESULTS: Patients with newly diagnosed LV dysfunction were prospectively enrolled. Patients underwent CAC imaging and were followed until an etiologic diagnosis of cardiomyopathy was made...

BACKGROUND: Lifestyle, environmental, and genetic factors substantially influence cardiovascular disease (CVD) risk. We aimed to explore epidemiologic trends in coronary artery calcium scores (CACS), as a marker of CVD, along with possible differences by geographic area and study period in separate East Asian populations. METHODS: We generated 3 matched groups (n=702) using a propensity scoring approach derived from a Korean (N=48,901) and Chinese cohort (N=927) as follows: (1) A recent Chinese group and (2) recent Korean group, both of whom underwent CACS scanning from 2012-2014; and (3) a past Korean group who underwent CACS scanning 8-10years before the index group (2002-2006)...

BACKGROUND: Percutaneous coronary intervention (PCI) of lesions with coronary arterial calcification (CAC) is common and has been historically associated with an increased risk of adverse events. Whether the association between target lesion calcification (CAC) and outcomes differ across drug-eluting stent generation or between patients with high vs. low residual platelet reactivity (PR) remains unknown. We assessed the association of CAC with adverse ischemic and bleeding events among patients undergoing contemporary PCI with drug-eluting stents (DES)...

BACKGROUND: In end-stage renal disease (ESRD), coronary artery calcification (CAC) and inflammation contribute to cardiovascular disease (CVD). Statins do not improve survival in ESRD patients and their effect on vascular calcification is unclear. We explored associations between CAC, inflammatory biomarkers, statins and mortality in ESRD. MATERIAL AND METHODS: In 240 ESRD patients (63% males; median age 56 years) from cohorts including 86 recipients of living donor kidney transplant (LD-Rtx), 96 incident dialysis patients and 58 prevalent peritoneal dialysis patients, associations of CAC score (Agatston Units, AUs), interleukin-6 (IL-6) with high-sensitivity C-reactive protein (hsCRP), tumour necrosis factor (TNF), use of statins and all-cause mortality were analysed...

BACKGROUND AND AIMS: Statins reduce subclinical atherosclerosis and premature atherosclerotic cardiovascular disease (ASCVD) in patients with familial hypercholesterolemia (FH). However, some FH patients still develop ASCVD despite statin therapy. We compared subclinical atherosclerosis assessed by carotid plaque presence and intima media thickness (C-IMT), in long-term statin-treated FH patients and healthy controls. Furthermore, we analysed whether carotid ultrasonography findings associated with subclinical coronary atherosclerosis...

BACKGROUND AND AIMS: Although comprehensive risk factor modification is recommended, a uniform management strategy does not necessarily prevent secondary events in patients with coronary artery disease (CAD). Therefore, identification of high-risk patients who may benefit from more intensive interventions may improve prognosis. Carotid ultrasound can reliably identify systemic atherosclerosis, and carotid plaque and intima-media thickness (IMT) are known independent risk factors for CAD...
