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
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.
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 SELECT™ 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.
Air pollution is a major cause of cardiovascular morbidity and mortality. The components of air pollution responsible and the mechanisms through which they might mediate these harmful effects remain only partially understood. We hypothesise that these adverse effects are mediated by combustion derived air pollutants and that even a brief exposure will effect heart and blood vessel function. We assess the effect of dilute diesel exhaust inhalation at levels encountered in urban road traffic on heart and blood vessel function in patients with stable coronary heart disease.
The purpose of this study was to assess whether interpatient variability in the platelet response to clopidogrel is partly due to polymorphisms of the hepatic cytochrome P450 (CYP450)3A and of the clopidogrel-P2Y12 receptor genes.
