Filter by:Few data are available about the late patency of side branches in association with the currently used stent types and implantation techniques.
This study is to compare the safety and performance of two stents coated with the same drug (the TAXUS Element Paclitaxel-Eluting Coronary Stent System and the TAXUS Express2 Paclitaxel-Eluting Coronary Stent System).
The ability of a new SSFP-based BOLD MRI sequence to assess myocardial oxygenation changes in response to coronary flow changes induced by adenosine and increased CO2-partial pressure will be examined in healthy volunteers and patients with suspected coronary artery disease. Also the susceptibility of a new SSFP-based BOLD sensitive MRI sequence to changes in arterial oxygenation will be examined. This will help understand the physiologic basis of oxygen sensitive imaging of the heart.
Endothelial dysfunction is an early marker of atherosclerosis and is found in patients (pts) with coronary (CAD) and peripheral artery disease (PAD). Statin-therapy has been shown to improve endothelial function in pts with CAD or PAD by reducing LDL-cholesterol and inflammatory markers. B-group vitamin-supplements have variable been reported to have positive or neutral effects on endothelial function. Therefore, we want to compare the effect of rosuvastatin and B-group vitamin supplementation on endothelial function of the forearm resistance vessels in pts with cardiovascular disease.
Patients with type 2 diabetes mellitus suffer from accelerated coronary artery disease. We will assess the effects of exercise training on coronary endothelial function, vascular structure, and inflammation both in serum and skeletal muscle biopsies, as well as expression of diabetes candidate genes.
It is unclear which stenting strategy will be optimal for true bifurcation coronary lesions.
Adequate platelet inhibition before percutaneous coronary intervention (PCI) reduces peri-procedural and long-term ischemic complications. Documented reduced response to clopidogrel has been associated with subsequent major adverse cardiovascular events. Strategies to optimize platelet inhibition pre-PCI are under investigation. This study sought to evaluate the effect on platelet aggregation of four different dosing regimens of clopidogrel given before elective PCI.
Increasing lesion complexity in percutaneous coronary interventions (PCI) has warranted the use of overlapping drug-eluting stents. Whether the substantial impairment of arterial healing observed at sites of overlap in preclinical pathologic studies persists in patients undergoing PCI is unknown. Consecutive patients with long lesions in native coronary vessels requiring stents in overlap are prospectively randomized to receive multiple sirolimus-,paclitaxel polymer-or zotarolimus eluting stents versus bare metal stents. The completeness of stent struts coverage and/or late malapposition are evaluated by Optical Coherence Tomography at 6 months follow-up
Surgical revascularization has proven its efficacy in term of morbidity and mortality in patients with multivessel coronary disease and poor left ventricular function. Nevertheless, if left ventricle is severely dilated, the improvement of global contractility and reduction of volumes is frequently absent after CABG even if substantial amount of myocardial viability is present. A value of > 140 ml for end systolic volume has been proposed as the cut off for the absence of recovery after revascularization. Recently, a reduction of cardiac volumes and improvement of regional and global contractility has been demonstrated in patients with advanced ischemic heart disease, severe dilation of left ventricle and poor candidates for revascularization after injection of stem cells in territories with residual viability.
This First In Man study is a prospective, multicentre, single blind, randomized, controlled clinical trial of the CINATRA™ ISA 247 Coated Coronary Stent System as compared to the CINATRA™ Coronary Stent System. The study will enroll up to 100 evaluable patients at up to 7 sites. Clinical follow up will occur at 1 month, 6 months, and 1, 2, 3, 4 and 5 years post procedure. Repeat angiography and IVUS will be performed at the 6 month follow up time point for all subjects.
