Active clinical trials for "Coronary Artery Disease"

The primary aim of this study is to establish how frequently patients with coronary artery disease present or develop two anxiety disorders (panic disorder and generalized anxiety disorder) in the two years following a medical intervention for their heart. A second objective is to assess the impact of these anxiety disorders on the health of these patients.

Intra-Aortic Balloon Pumps (IABP) is a widely used and effective left ventricular adjuvant therapy. IABP is an inflatable device placed in the aorta that inflates with diastole and deflates with systole. The aim of this study is to investigate the outcome of patients treated With IABP, and to evaluate the short-term and long-term outcomes of patients with IABP.

Bifurcation lesions (BL) on coronary arteries account for 15-20 % of all performed percutaneous coronary interventions (PCI). Preferred approach for treatment of most bifurcation lesions is the stepwise provisional stent strategy with main branch-only stenting followed by provisional balloon angioplasty with or without stenting of the side branch (SB). Stenting of the side branch is indicated when the angiographic result in SB is clearly suboptimal and when flow remains reduced. Upfront use of two stent techniques may be indicated in very complex lesions with large calcified side branches ( most likely to supply at least 10% of fractional myocardial mass), with a long ostial side branch lesion (>5mm) or anticipated difficulty in accessing an important side branch after main branch stenting, and true distal LM bifurcations. From a technical point of view, we propose a "Provisional DCB approach" that differs from the standard provisional approach with obligatory SB predilation and good lesion preparation. In case of an adequate result of predilation, the procedure on the SB ends with the DCB deployment. This is followed by main branch stenting with DES, finished with POT. Final 'kissing' balloon dilation is generally not recommended because there is no advantage from final kissing with the one-stent technique. With this approach, there is no need for re-wiring, re-ballooning, side branching and wire jailing and final kissing. This technique is close to a contemporary approach to bifurcation lesions based on the fundamental philosophy of the European Bifurcation Club (EBC): keep it simple, systematic, and safe, with a limited number of stents that should be well apposed and expanded with limited overlap, with respect of the original bifurcation anatomy.

The aim of the study is to assess continued safety and efficacy of the SeQuent® SCB. The product under investigation will be used in routine clinical practice according to the latest European Society of Cardiology (ESC) guidelines and according to the Instructions for Use (IFU). Those data that are obtained in routine clinical use will be documented in the Case Report Form (CRF).

The study design is a prospective, multicenter, observational, single-arm post-approval study using data collected in the National Cardiovascular Data Registry (NCDR®) CathPCI Registry®.

The CAREPATH will conduct Technical Validation and Usability (TVU) study by involving ≥ 45 target end users (16 patients with MCI or mild dementia with their informal caregivers and 16 healthcare professionals from various disciplines) and Clinical Investigation (CI) study involving ≥ 200 patients (≥ 100 users to pilot the CAREPATH platform and ≥ 100 patients as reference cases). Both of these pilot studies will be coordinated in four European countries (Spain, Romania, Germany and UK) with diverse health and social care systems, ICT landscape/digital maturity of healthcare provision and dementia national programs, which will allow for strengthening the evidence base on health outcomes and efficiency gains. The CAREPATH outcomes can be summarized as: An Integrated Care Platform that jointly addresses multimorbidity, dementia and diminished intrinsic capacity and optimally manages healthcare interventions for its users (patients, informal caregiver, healthcare providers, etc). Technical Validation and Usability (TVU) study involving over 45 users and Clinical Investigation (CI) involving over 200 patients that will be conducted in four European countries (Spain, Romania, Germany and UK) during two years and mobilizing the other necessary actors, such as caregivers and healthcare professionals, for the validation of healthcare interventions. Dementia / Multimorbidity Guidelines that will be conceived for best healthcare delivery. Health Economics Impact Assessment for healthcare cost effectiveness and care provision equalities. The incremental cost-effectiveness and the incremental cost-utility ratio would allow revealing the incremental cost (or the potential savings) per unit of benefit of switching from usual care to CAREPATH-an integrated patient-centred approach- in multimorbid elderly patients with dementia, and therefore, to determinate whether the CAREPATH approach would be considered as a cost-effective alternative.

Prospective, multi-centre, open-label, single-armed, non-interventional observational clinical investigation designed to enrol 2000 octo- and nonagenerian all-comer patients with coro-nary artery disease in up to 37 sites in Germany, Switzerland and Austria. Patients underwent PCI using at least one Supraflex Cruz Sirolimus Eluting stent as per current practice and will be followed up for 12 months.

Patients will undergo intracoronary imaging using combined optical coherence tomography-fluorescence lifetime imaging (OCT-FLIm) during percutaneous coronary intervention, and the obtained imaging data will be used to assess the efficacy of this dual-modal catheter imaging strategy in characterizing high-risk plaque.

Coronary-related myocardial ischemia can result from obstructive epicardial stenosis or non-obstructive causes including coronary microcirculatory dysfunction and vasomotor disorders. This prospective study has been created in order to provide knowledge in the field of non-obstructive coronary artery disease.

In 1970, the first percutaneous balloon coronary angioplasty opened a new chapter of interventional therapy. However, the incidence of intracoronary restenosis was about 30%. Subsequently, bare metal stents and drug-eluting stents (DES) reduced the incidence of in-stent restenosis (ISR) to 5%-10% and it was still a bottleneck treated by percutaneous coronary intervention (PCI). Currently, ISR is mainly treated by balloon angioplasty, stent implantation and coronary artery bypass grafting. In 2014, the guidelines of the European Society of Cardiology recommended that drug balloon therapy (DCB) and new generation DES should be the preferred strategies for ISR treatment. Compared with DES, DCB treatment can avoid the inflammation of intima caused by multi-layer stent strut, and reduce the risk of intimal hyperplasia and thrombosis in stent. However, DCB lacks sustained radial support. Even if the residual stenosis is less than 30% after sufficient pre-dilation, the elastic retraction of the intima still exists. In addition, the antiproliferative effect of paclitaxel is significantly worse than that of sirolimus and its derivatives, and there is a lack of long-term sustained release of anti-proliferative drugs. Compared with DCB, DES can obtain long-term stable radial support and long-term anti-proliferation effect, but stent struts exposed in the vascular lumen are at risk of stent thrombosis. The new generation of DES improves the design of stent platform, improves the polymer coating, and applies new anti-proliferative drugs. It effectively reduces the inflammation of vascular wall, speeds up the process of vascular re-endothelialization, promotes early vascular repair, and significantly reduces the incidence of stent thrombosis. Recent BIOLUXRCT, RESTORE and DARE studies provide more powerful evidence for the treatment of ISR by new generation DES. Quantitative flow ratio (QFR) is the second generation FFR detectional method based on coronary contrast image. The latest FAVOR II results also confirm that QFR is more sensitive and specific than quantitative coronary analysis (QCA) in the diagnosis of myocardial ischemia caused by coronary artery stenosis. However, there is no report of ISR treated with DCB under the guidance of QFR. The aim of this study was to evaluate the safety and efficacy of DCB in the treatment of in-stent restenosis in patients with coronary heart disease (CHD) under the guidance of QFR compared with DES implantation.
