B-type natriuretic peptide measurements in diagnosing congestive heart failure in the dyspneic emergency department patient.

摘要: Increasing focus has recently been directed toward the different parameters of drug-eluting stents-stent design, delivery-vehicle materials, and drug properties-and manner in which each these elements may affect function stents. Several specific characteristics design restenosis, although optimization often presents a choice between acute procedural success long-term biological stability. The influence such as strut thickness cell configuration is described. Polymer material frequently used to coat stents, some agents, paclitaxel, can be attached directly stent's surface, obviating need for polymer layer. properties agents stents how those delivery outcome are discussed, disease state target vessel on stent safety efficacy.
