Composite rate of death, myocardial infarction (MI) or target vessel revascularization (TVR) inhospital, and at 6 months 2. Composite rate of inhospital death, MI or TVR and major bleeding 3. Major and minor bleedings 4. Total vascular complications 5. Post-procedure renal failure Randomization: Bivalirudin versus unfractioned heparin followed by protamine at the end of the PCI procedure Sample size: Assumed incidence of inhospital major bleeding of 6% in UFH + protamine and of 2% in bivalirudin group; for a power of 80% and a level of 0.05 for each group 425 patients are needed. An interim analysis will be performed after the enrolment of 425 (50%) patients. Follow-up: Inhospital, and 6-month clinical follow-up (out-patient clinic or by phone)
Aim of this study is to evaluate whether the length of coronary segments, assessed by an experienced operator, using the "optimal view" of standard 2-dimensional coronary angiography, is over/underestimated with respect to the one evaluated automatically with the help of a 3-dimensional coronary reconstruction model. Moreover, both techniques are compared with an "in-vivo" surrogate of the real length of the coronary segment under evaluation, i.e. an intra-coronary marker guide-wire, which is a wire with markers placed at fixed and known distance along its length in its distal (intra-coronary) part. Two hypotheses are tested: (1) the length of a coronary segment evaluated with a standard 2-dimensional "optimal view" over/underestimates the length assessed by a 3-dimensional coronary model that automatically detects the least foreshortened length of the segment under evaluation, and (2) the 3-dimensional model approximates more closely than standard 2-dimensional angiography, the real length of the segment detected by the marker guide-wire.
Coronary artery disease is the first cause of death related to atherothrombosis.
Evaluate the proportion of hyperlipaemic persons with known coronary heart disease achieving ldl-c goal as defined by the national cholesterol education program (NCEP) adult treatment panel (ATP) III guidelines
Physicians tend to always use the lowest dose of statins to initiate therapy even in subjects who require large reductions in cholesterol. The study evaluates if selecting the starting dose based on baseline and target LDL-C cholesterol would provide better results (ie proportion of subjects resching target)
The purpose of this study is to establish safety and feasibility of utilizing Adipose-Derived Stem and Regenerative Cells (ADRC's) in patients who have suffered a ST-elevation acute myocardial infarction.
European physicians tend to always use the lowest dose of statins to initiate therapy even in subjects who require large reductions in cholesterol. The study evaluates if selecting the starting dose based on baseline and target LDL-C cholesterol would provide better results (ie proportion of subjects resching target)
The primary objective of this study is to evaluate the safety and effectiveness of a direct stenting technique compared to conventional stenting with pre-dilatation strategy using the CoStar Paclitaxel-eluting coronary stent system for the treatment of a single de novo lesion in a native coronary artery ≤ 25 mm long in a native coronary artery 2.5-3.5 mm diameter.
Enoxaparin 0.75mg/kg BW is not inferior to weight adjusted unfractionated heparin as anticoagulation for PCI
This multicenter, prospective, observational registry will evaluate the safety and performance of the CYPHER SELECTâ„¢ Sirolimus-eluting Coronary Stent, and of all future generation of commercially approved Cordis Sirolimus-eluting Stents (SES), in routine clinical practice. Its objective is to measure the incidence and identify the predictors of acute, sub-acute and late stent thrombosis and Major Adverse Cardiac Events (MACE). Additional analyses will be performed in patient sub-populations, such as diabetes, in-stent restenosis (ISR), acute myocardial infarction (AMI) and multivessel coronary disease.
