It is a predictor of PERIPHERAL ARTERIAL DISEASE.Logistic Models: Statistical models which describe the relationship between a qualitative dependent variable (that is, one which can take only certain discrete values, such as the presence or absence of a disease) and an independent variable. A common application is in epidemiology for estimating an individual's risk (probability of a disease) as a function of a given risk factor.Rabbits: The species Oryctolagus cuniculus, in the family Leporidae, order LAGOMORPHA.

There are three subtypes: (1) atherosclerosis with fatty deposits in the ARTERIAL INTIMA; (2) Monckeberg's sclerosis with calcium deposits in the media and (3) arteriolosclerosis involving the small caliber arteries. Clinical signs include HEADACHE; CONFUSION; transient blindness (AMAUROSIS FUGAX); speech impairment; and HEMIPARESIS.Diabetes Complications: Conditions or pathological processes associated with the disease of diabetes mellitus. Due to the impaired control of BLOOD GLUCOSE level in diabetic patients, pathological processes develop in numerous tissues and organs including the EYE, the KIDNEY, the BLOOD VESSELS, and the NERVE TISSUE.Peripheral Blood Stem Cell Transplantation: Transplantation of stem cells collected from the peripheral blood. It is a less invasive alternative to direct marrow harvesting of hematopoietic stem cells. Enrichment of stem cells in peripheral blood can be achieved by inducing mobilization of stem cells from the BONE MARROW.Blood Cells: The cells found in the body fluid circulating throughout the CARDIOVASCULAR SYSTEM.Tantalum: Tantalum.

- The global vascular stents market is projected to reach USD 17.68 billion by 2021 from USD 12.21 billion in 2016, at a CAGR of 7.7% from 2016 to 2021. (reportlinker.com)
- Coronary stents was the highest revenue-generating and fastest growing segment in 2015, registering a CAGR of 9.5% during the analysis period, owing to increasing advances in the field of interventional cardiology coupled with the progress of minimally invasive techniques. (beforeitsnews.com)
- Our study suggests the minimally invasive approach shows real promise, and we are embarking on a large, randomized study of the two procedures to develop guidelines that can be used for determining when a stent is likely to be best and when a bypass cannot be avoided. (jhu.edu)
- In contrast to minimally invasive stenting, a so-called femoral-popliteal bypass requires a large incision to open the leg, and the surgical attachment of a piece of vein or a synthetic tube above and below the blockage to reroute blood flow. (jhu.edu)
- Because angiographically guided stent implantation is a highly specialized procedure, proper equipment is necessary for imaging and for the procedure itself. (medscape.com)
- Patients who received stents had a 31 percent risk of needing another procedure to restore blood flow within 24 months, while those who received a bypass had a 54 percent chance of needing another intervention. (jhu.edu)

Surface of the stent3
- The covering may be on the exterior surface of the stent, or on the interior surface of the stent, or both. (google.co.uk)
- This was no easy task, since the outer surface of the stent must be tissue-compatible and the inner surface blood-compatible. (mpo-mag.com)
- To answer this question, the research team built an experiment in which the surface of the stent was exposed to a flow of synthetic blood plasma at varying temperatures, pressures and flow speeds. (mpo-mag.com)
