Epidemiological studies indicate that hyperuricaemia is an independent risk factor for cardiovascular disease. Alongside uric acid formation, increased xanthine oxidase activity also results in the formation of oxidative free radicals and superoxide particles. Oxidative stress significantly contributes to the development of cardiovascular disease, including endothelial cell dysfunction, atherosclerosis, vascular calcification and impaired myocardial energetics. Allopurinol, a competitive xanthine oxidase inhibitor, in addition to reducing serum uric acid levels, can act as a free radical scavenger...

Chronic kidney disease (CKD) mineral and bone disorders (CKD-MBD) may lead to low bone mineral density (BMD) and vascular calcification (VC), but links to the latter are unclear. Here we investigated associations between BMD, coronary artery calcium (CAC) scores, and histological signs of VC in end-stage renal disease (ESRD) patients undergoing living-donor kidney transplantation (LD-Rtx). In 66 ESRD patients (median age 45 years, 68% males), BMD (by dual-energy X-ray absorptiometry, DXA), CAC score (by computed tomography, CT; n = 54), and degree of VC score (graded by histological examination of epigastric artery specimens collected at LD-Rtx; n = 55) were assessed at the time of LD-Rtx...

The continuing increase in the prevalence of diabetes mellitus in the general population is predicted to result in a higher incidence of cardiovascular disease. Although the mechanisms of diabetes mellitus-associated progression of atherosclerosis are not fully understood, at clinical and pathological levels, there is an appreciation of increased disease burden and higher levels of arterial calcification in these subjects. Plaques within the coronary arteries of patients with diabetes mellitus generally exhibit larger necrotic cores and significantly greater inflammation consisting mainly of macrophages and T lymphocytes relative to patients without diabetes mellitus...

BACKGROUND: Heavy coronary artery calcification is responsible for stent underexpansion, which is associated with increased in-stent restenosis. Here we report a case in which optical coherence tomography (OCT) demonstrated that the metal component of an underexpanded stent previously implanted in a heavy calcified lesion had been completely removed after ablation with rotational atherectomy. CASE PRESENTATION: An 83-year-old man with exertional angina was referred to our hospital...

The autopsy of a fetus at 23 weeks gestational age revealed a partial pericardial defect with subsequent herniation of parts of the left ventricle. The myocard was impinged by the fibrous rim of the residual pericardium. Microscopic examination showed signs of recurrent myocardial infarctions with necrosis, calcification, fibrosis and prominent deposition of iron.Partial pericardial defects result from incomplete fusion of the pleuropericardial membrane and may lead to myocardial infarction via compression of the coronary arteries...

In chronic kidney disease (CKD), overweight and mild obesity have shown the lowest cardiovascular (CV) risk. However, central obesity has been directly associated with CV risk in these patients. This bidirectional relationship of body mass index (BMI) and central obesity prompted us to evaluate CV risk based on a combination of BMI and waist-to-hip ratio (WHR) in nondialysis CKD patients. We included 1078 patients with CKD stage 2 through 5 (nondialysis) enrolled in a nationwide prospective cohort of Korea...

Cardiovascular disease (CVD) is a complex multifactorial and polygenetic disease in which the interaction of numerous genes, genetic variants, and environmental factors plays a major role in its development. In an attempt to demonstrate the association between certain genetic variants and CVD, researchers have run large genomic wild association studies (GWAS) in recent decades. These studies have correlated several genomic variants with the presence of CVD. Recently, certain polymorphisms in the phosphatase and actin regulator 1 (PHACTR1) gene have been shown to be associated with CVD (i...

Kawasaki disease is a well-known cause of acquired cardiac disease in the pediatric and adult population, most prevalent in Japan but also seen commonly in the United States. In the era of intravenous immunoglobulin (IVIG) treatment, the morbidity associated with this disease has decreased, but it remains a serious illness. Here we present the case of an adolescent, initially diagnosed with Kawasaki disease as an infant, that progressed to giant aneurysm formation and calcification of the coronary arteries...

BACKGROUND: -The burden of subclinical atherosclerosis in asymptomatic individuals is heritable and associated with elevated risk of developing clinical coronary heart disease (CHD). We sought to identify genetic variants in protein-coding regions associated with subclinical atherosclerosis and the risk of subsequent CHD. METHODS AND RESULTS: -We studied a total of 25,109 European ancestry and African-American participants with coronary artery calcification (CAC) measured by cardiac computed tomography and 52,869 with common carotid intima media thickness (CIMT) measured by ultrasonography within the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) Consortium...

A 48-year-old man from West Africa was evaluated for dyspnea. Echocardiography showed an echolucent mass at the left ventricular apex surrounded by a dense ridge of tissue, suggesting endomyocardial fibrosis (EMF). Doppler echocardiography showed restrictive hemodynamics and intramyocardial coronary blood flow at the hypertrophied apex, suggesting apical hypertrophic cardiomyopathy (ApHCM) with calcified thrombus. Cardiac magnetic resonance imaging showed a thickened myocardium with apical cavity obliteration and endomyocardial calcification, and gadolinium contrast demonstrated marked bright subendocardial and diffuse patchy intramyocardial hyperenhancement in the hypertrophied apical wall segment, confirming coexistence of EMF and ApHCM...

Prior studies identified the incremental value of non-invasive imaging by CT-angiogram (CTA) to detect high-risk coronary atherosclerotic plaques. Due to their superficial locations, larger calibers and motion-free imaging, the carotid arteries provide the best anatomic access for the non-invasive characterization of atherosclerotic plaques. We aim to assess the ability of predicting obstructive coronary artery disease (CAD) or acute myocardial infarction (MI) based on high-risk carotid plaque features identified by CTA...

BACKGROUND: In-stent neoatherosclerosis is characterized by the delayed appearance of markers of atheroma in the subintima, but the pathophysiology underlying this new disease entity remains unclear. METHODS AND RESULTS: We collected 20 human coronary artery stents by removal from explanted hearts. The mean duration of stent implantation was 34 months. In all samples, neoatherosclerosis was detected, particularly in peristrut areas. It consisted of foam cells and cholesterol clefts, with or without calcification, associated with neovascularization...

REVIEW
R Nicoll, M Henein
Arterial calcification is commonly seen in atherosclerosis, chronic kidney disease (CKD) and diabetes and has long been considered a natural progression of atherosclerosis. Yet it is a systemic condition, occurring in a wide and diverse range of disease states and no medical treatment for cardiovascular disease has yet found a way to regress it; on the contrary, lipid-lowering therapy may worsen its progression. Although numerous studies have found associations between calcification and biomarkers, none has yet found a unifying mechanism that explains the calcification found in atherosclerosis, CKD or diabetes and many of the biomarkers are equally associated with atheroma development and cardiovascular events...

OBJECTIVES: Coronary stent underexpansion is a known risk factor for in-stent restenosis and stent thrombosis. There are limited options once noncompliant balloons have failed to achieve optimal stent expansion. Excimer Laser Coronary Angioplasty with contrast medium injection is one possibility, but not readily available. Rotational atherectomy is an alternative, and has been described in case reports, but concerns exist regarding safety. METHODS: All consecutive patients undergoing rotational atherectomy for symptomatic in-stent restenosis due to stent underexpansion resistant to noncompliant balloon postdilatation between January 2005 and December 2015 were analysed...
