Peri-aortic hematoma has been recently described as a potentially life-threatening complication following transcatheter aortic valve replacement (TAVR). Patient- and procedure-related factors exist that predispose to peri-aortic hematoma formation, which can progress to myocardial rupture at the aortic root-myocardial junction. While conservative therapy with blood pressure control is the expectant management following peri-aortic hematoma formation, myocardial rupture can occur at the site of the aortic annulus...

BACKGROUND: The biggest problem in routine hemodialysis therapy is possibly the blood pressure fall experienced by patients during dialysis. In contrast, in medium- and long-term hemodialysis therapy, the main problem might be deterioration of arteriosclerosis because of medial calcification associated with dialysis vintage. Both problems are caused by an autonomic imbalance or structural change in the blood vessels. Inflammation due to extracorporeal blood circulation is another possible cause...

Background: Major acid-base variations during dialysis and the imbalances in serum calcium levels intensified by them play a role in cardiovascular damage of hemodialysis patients. Early vascular walls modifications can be objectified by determining the pulse wave velocity (PWV) - a marker of vascular stiffness that is associated with increased risk of cardiovascular events. Material and methods: This was a prospective study conducted on 63 chronic hemodialysis patients with diuresis above 500 mL/ 24 hours and predialysis blood pressure below 160 mmHg (treatment controlled) randomized in two groups for 12 months - the study group receiving interdialitic oral sodium bicarbonate doses and control group, without oral sodium bicarbonate supplementation, but receiving higher bicarbonate prescriptions in dialysis...

BACKGROUND/PURPOSE: Critical hand ischemia (CHI) can be devastating and may result in amputation. Distal vessel calcification has been shown to be a major factor in causing CHI. Atherectomy in the upper extremities is not typically considered due to the small anatomy; however, the Diamondback 360° Peripheral Orbital Atherectomy System (OAS) (Cardiovascular Systems, Inc.) can access treatment areas with a reference vessel diameter of 1.5mm. METHODS/MATERIALS: A retrospective, observational, single center (Merit Health Center, Jackson, MS) analysis of 11 CHI patients with calcific disease of the radial artery treated with orbital atherectomy (OAS) was completed...

INTRODUCTION: Marathon running is presumed to improve cardiovascular risk, but health benefits of high volume running are unknown. High resolution coronary computed tomography angiography (CCTA) and a cardiac risk factor assessment were completed in women with long term marathon running histories to compare to sedentary women with similar risk factors. METHODS: Women who had run at least one marathon per year for 10-25 years underwent CCTA, 12-lead ECG, blood pressure and heart rate measurement, lipid panel, and a demographic/health risk factor survey...

When using vitamin D, the most important clinical problems are hypercalcemia, hyperphosphatemia, and vascular calcification. VS-105 is a novel vitamin D receptor (VDR) analog. In the present study, we compared the effects of VS-105 and paricalcitol on chronic kidney disease-mineral bone disorder (CKD-MBD) in a CKD rat model. We used male Sprague-Dawley (SD) rats and performed 5/6 nephrectomy at 8-9 weeks. At 10 weeks, the rats were classified into five groups and administered vehicle, low-dose paricalcitol (LP, 0...

Cardiovascular diseases are the leading cause of mortality among women in several countries. Early detection of subclinical atherosclerosis (SA) could enable the adoption of preventive measures to avoid cardiovascular events. This study aimed to determine the prevalence of SA in Brazilian asymptomatic postmenopausal women in Framingham Risk Score (FRS) low and intermediate groups. Computed tomography (CT) and ultrasound (US) scans were performed in 138 asymptomatic postmenopausal women (56.1 ± 4.9 years of age) to survey for coronary artery and aortic calcification (CT scan) and assess carotid intima-media thickness (CIMT) and identify carotid plaques (US)...

Blood vessels function as conduits for distribution of blood throughout the circulatory system. Large arteries, in addition to the essential conduit function, also serve to dampen the effect of pulsatile ventricular ejection that generates pulsatile pressure with each cardiac cycle; that is, they exhibit a 'cushion' function. The conduit function can be compromised by intimal effects that cause obstruction to flow, generally attributed to plaque formation due to intimal changes affected by atherosclerotic processes...

BACKGROUND: The most common valve diseases are calcific aortic stenosis (AS) and aortic regurgitation (AR). The former is characterized by thickening of valve leaflets followed by progressive calcification, which produces progressive aortic valve (AV) narrowing, increased pressure afterload on the left ventricle (LV) and subsequent LV hypertrophy. On the other hand, AR is due to malcoaptation of the valve leaflets with resultant diastolic reflux of blood from aorta back to the LV producing volume and pressure overload and progressive LV dilatation...

BACKGROUND: Risk factors measured in early life have been shown to predict coronary artery calcium (CAC) in adulthood. However, limited data exist on when risk factor profiles of those who develop CAC diverge from those who do not. We investigated the associations of coronary heart disease risk factor trajectories beginning in adolescence and CAC measured at middle-age. METHODS: CAC was measured among 589 participants aged 39-45years in whom cardiovascular risk factors (serum lipids, blood pressure, body mass index, physical activity, smoking habits, and fruit, vegetable, fish, and butter intake) had been collected in 1980, 1983, 1986, 2001, and 2007 as part of the Cardiovascular Risk in Young Finns Study...

The extracellular calcium-sensing receptor (CaSR) is a unique G protein-coupled receptor (GPCR) activated by extracellular Ca(2+) and by other physiological cations including Mg(2+), amino acids, and polyamines. CaSR is the most important master controller of the extracellular Ca(2+) homeostatic system being expressed at high levels in the parathyroid gland, kidney, gut and bone, where it regulates parathyroid hormone (PTH) secretion, vitamin D synthesis, and Ca(2+) absorption and resorption, respectively. Gain and loss of function mutations in the CaSR are responsible for severe disturbances in extracellular Ca(2+) metabolism...

BACKGROUND AND AIMS: Type 2 diabetes (T2D), low-density lipoprotein-cholesterol (LDL-c), body mass index (BMI), blood pressure and smoking are established risk factors that play a causal role in coronary artery disease (CAD). Numerous common genetic variants associating with these and other risk factors have been identified, but their association with CAD has not been comprehensively examined in a single study. Our goal was to comprehensively evaluate the associations of established and emerging risk factors with CAD using genetic variants identified from Genome-wide Association Studies (GWAS)...
