Filter by:Although statin prior to PCI has favorable effects in stable angina and ACS except ST elevation MI (STEMI), there have been few studies for STEMI. Celik T et al. reported in patients with STEMI that prior statin use may improve coronary blood flow after PCI in patients with AMI, possibly by its beneficial effects on microvascular function. But this study was retrospective, non-randomized study and evaluated the effects for chronic statin therapy not acute high dose effect. Therefore, the investigators investigated whether acute high-dose statin prior to primary PCI in ST segment elevation myocardial infarction can have beneficial effect or not for periprocedural period and 30 days-cardiac events.
The purpose of this study is to determine the effect of clopidogrel or aspirin reactivity as measured by a point-of-care platelet function assay on thrombotic or bleeding events after percutaneous coronary intervention (PCI) with drug eluting or bare metal stent. Methods: Platelet reactivity on clopidogrel and aspirin therapy is measured before PCI with VerifyNow (Accumetrics Inc.,San Diego, CA, USA) P2Y12 or aspirin assay respectively in 1000 consecutive patients from 20 centers in France undergoing coronary angioplasty with stent. Exclusion criteria are: Acute myocardial infarction, treatment with vitamin K antagonists and the use of antiGP2b3a before PCI. All patients are pre-treated with clopidogrel and aspirin. Non-response to aspirin or clopidogrel is determined according to the result of the VerifyNow assay (cut off : < 15 % for P2Y12 and > 550 ARU for aspirin). The primary end point is the occurrence of definite or probable stent thrombosis (ARC definition) and the secondary end-points include global and cardio-vascular mortality, non fatal myocardial infarction and major bleeding. A clinical evaluation is scheduled at discharge and by telephone contact at one month and one year.
Most doctors who use the new drug-eluting stents for the treatment of long coronary narrowings tend to cover the full length of the lesion with long or multiple stents. The investigators hypothesized that a policy of spot-stenting, i.e., stenting of only the very tight parts of the coronary narrowing, might result in better outcomes by means of avoiding multiple stents that have been associated with significant complications such as late stent thrombosis.
The investigators evaluated whether primary implantation of a self-expanding nitinol stent yielded anatomical and clinical benefits superior to those afforded by percutaneous transluminal angioplasty with optional secondary stenting.
The purpose of this study to compare balloon angioplasty (PTA) vs. cutting balloon angioplasty (CB-PTA) in terms of patency and postintervention inflammation in peripheral artery disease.
The purpose of the Metricath Gemini System is to pre-dilate the target treatment area, take arterial lumen measurements in a native section of artery or within the deployed stent and perform further dilation of the deployed stent if required. In this manner, the Metricath Gemini System can assist the Interventionalist by providing arterial measurements prior to stenting, performing pre-stenting angioplasty, taking within stent measurements to help determine if the stent is fully deployed, and by performing post-stenting dilations to further dilate the stent if required.
Early promising data are published focusing on the role of manual thrombus aspiration devices in patients with ST segment elevation (STEMI). The aim of our single center randomized study is to evaluate the early and late effect of thrombus aspiration device (AD) after every stage during Primary PCI in the set-up of STEMI population. Our hypothysis is that preforming thrombus aspiration after every stage of primary PCI may give early and late advantages compared to the standard primary PCI technique.
This study is a randomized, double-blind, multi-center study designed to compare differences in rates of myonecrosis (measured as an elevation of CK-MB ratio ≥ 2 times ULN) within 24 hours following low-medium risk percutaneous coronary intervention (PCI) in aspirin or clopidogrel non-responsive patients who are randomized to heparin with or without eptifibatide therapy during PCI. The primary objective of this study is to determine if the use of eptifibatide is associated with a significant difference in post-PCI myonecrosis (measured as an elevation of CK-MB ratio ≥ 2 times upper limit of normal [ULN]) within 24 hours of low-medium risk PCI in patients who are aspirin or non-responsive as determined by VerifyNow Aspirin and P2Y12 testing.
The objective of this randomized trials is to evaluate, among coronary artery disease patients who have just had either angioplasty or stents, whether a novel intervention based on feedback of individualized risk profiles framed as the opportunity to reduce one's biological age is more effective after two years in reducing mortality and major cardiovascular morbidity (specifically, myocardial infarction, stroke, class II-IV angina, and severe ischemia) than the standard risk reduction approach, which is framed as one's opportunity to reduce future risk. The novel strategy is based on the theory of net-present value and is tested in coronary artery disease patients who have a high risk of adverse outcomes by two years.
The anticipation of pain and discomfort, a diagnosis, and other intrinsic unknowns make patients anxious both prior to and during a procedure. Therefore, the main goal of sedation with analgesia used during various diagnostic, therapeutic, or surgical procedures is to relieve this anxiety, discomfort, and pain, which are all interrelated. The optimal level of sedation for any given patient is one that allows the patient to tolerate the procedure and provides an appropriate safety margin. This was a study designed to examine the safety and efficacy of AQUAVAN® Injection versus a commonly used approved sedative drug, midazolam HCl following pretreatment with fentanyl citrate injection (for pain relief) in producing sedation in patients undergoing single cardiac catheterization procedures.
