Filter by:The E-CABG registry is a multicenter, European registry collecting data on the preoperative characteristics, treatment strategies and outcome of patients undergoing isolated coronary artery bypass grafting (CABG).
The primary aim of the trial is to determine whether preventive PCI with bioabsorbable vascular scaffolds (BVS) (early period) or everolimus-eluting stents (middle and late period) plus optimal medical therapy (OMT) on functionally insignificant (FFR > 0.80) vulnerable coronary plaque, as determined by intracoronary imaging, would result in a significant reduction of the primary composite outcome of death from cardiac causes, target-vessel myocardial infarction (MI), target-vessel revascularization (TVR), and hospitalization for unstable or progressive angina at 2 years, when compared with OMT alone.
The purpose of this research study is to determine if Intravascular Ultrasound (IVUS) grayscale and VH (Virtual Histology)-IVUS pre-stenting can assess more accurately the location, amount, and type of a blockage than angiogram alone. Additionally, this study is to determine if IVUS grayscale and VH-IVUS guidance will result in improved acute and long term procedural outcome vs. bifurcation stenting with only angiographic guidance in native coronary arteries.
Background: About 5% of patients with acute coronary syndrome (ACS) have had previously ischemic stroke (IS) or transitory ischemic attack (TIA). This is a high-risk population, with a high incidence of ischemic events, and also of bleeding events. While the high ischemic risk in this population is attributed to a higher prevalence of cardiovascular risk factors, their predisposition to bleeding events is not well understood. Hypothesis: The increased bleeding risk in ACS patients with history of cerebrovascular event may be justified by a low platelet activity. Methods: Unicentric, prospective, case-control study, which included approximately 100 post-ACS patients with history of IS/TIA previously to the acute coronary event (Case Group) and 100 patients without IS/TIA (Control group). The groups were matched for gender, age, and ACS type and year of occurrence. All patients were taking aspirin, and the main exclusion criteria were use of dual antiplatelet therapy, previous hemorrhagic stroke, severe renal dysfunction, thrombocytopenia or coagulopathy. Main analysis: Platelet aggregation was evaluated by 6 methods: VerifyNow Aspirin®, VerifyNow P2Y12®, PFA 100®, thrombelastography (ReoRox®), light transmission aggregometry with ADP (LTA ADP) and epinephrine (LTA EPI) as agonists. Additional analysis: genetic, HDL transport and inflammatory evaliation
A single-centre double-blind placebo-controlled crossover randomised controlled trial to determine the physiological basis of glucagon-like peptide-1 receptor activation on exercise haemodynamics, as manifest through specific electrophysiological parameters measured by serial exercise stress testing, in those patients with reversible myocardial ischaemia and obstructive coronary artery disease confirmed by a baseline exercise test and coronary angiography respectively.
The current study is designed to test the hypothesis that compared to conventional treatment; endothelial function-guided treatment reduces adverse cardiovascular events in patients with non-obstructive coronary artery disease documented at clinically indicated coronary angiography.
The purpose of this study is to investigate the effects of interval training, based-intensity on 70% at 110% of oxygen consumption and workload attained on ventilatory anaerobic threshold, on aerobic functional capacity, autonomic modulation of heart rate, metabolic profile in patients with and without coronary artery disease.
Myocyte necrosis occurs frequently in elective percutanious percutaneous coronary intervention (PCI) and is associated with subsequent cardiovascular events. This study assessed the cardio- and reno-protective effect of remote ischemic preconditioning (RIPC) in patients undergoing elective PCI. 200 patients were randomized into 2 groups: 100 patients received RIPC (created by three 5-minute inflations of a blood pressure cuff to 200 mm Hg around the upper arm, separated by 5-minute intervals of reperfusion) < 2 hours before the PCI procedure, and the control group (n = 100).
Coronary heart disease (CHD) pose a serious health threat to population. PCI using drug eluting stents (DES), as a well-proved and booming measure in CHD management, is invasive and of high cost, however the knowledge about the real-life DES use and the efficacy and safety in China is limited. By consecutively recruiting first-ever PCI patients in 30 geographically representative highest-rank hospitals, this study will examine the prognosis in groups with different brands of DES, and various real-life factors, that may affect patients recovery after the procedure. Evidence for clinical practice and health resource allocation will be established based on the findings, to improve patients outcomes in future finally.
Coronary artery calcification (CAC) is a pandemic condition in elderly patients with coronary artery disease (CAD) and associated with worse prognosis. Although available data shows association between testosterone levels in men and CAD, the association between testosterone and CAC in old-aged male patients with CAD remains unknown. In this study, the relationship of serum testosterone levels with CAC score in elderly male patients with CAD was evaluated.
