Filter by:The study aims to evaluate the safety and effectiveness comparisons between warfarin, dabigatran, and rivaroxaban in routine clinical practice among Japanese non-valvular atrial fibrillation (NVAF) patients with concomitant coronary artery disease (CAD).
The objective of this study is to evaluate the effectiveness and safety of Synergy XD stent in the "real world" daily practice as compared with the other drug-eluting stents.
This study analyzes the impact of intraoperative Remimazolam infusion for postoperative sedation on the left ventricular global longitude strain (LV-GLS) patients undergoing cardiac surgery
Improvement of patients' care and outcome is largely based on development and validation of drugs and technologies, especially in rapidly evolving fields as Interventional Cardiology. In fact, even though the optimal efficiency of a cathlab can be influenced by Interventional Cardiologist's mental workload, stress' accumulation and performance, little if any attention is paid to the monitoring and optimization of his/her mental status. Electroencephalogram (EEG)-based neural-interfaces are able to estimate workload, fatigue and the degree of sleepiness through spectral analysis techniques. In particular, the amplitude of alpha waves is a widely validated indicator of mental engagement's level. Developing a low cost and highly feasible device to monitor and analyze operator's mental engagement level and performance could be extremely appealing, especially considering both the lack of data in literature for interventional disciplines and the recent technology developments.
This study is aimed to evaluate the effect of the optimal heart team implementation protocol on the stability of decision-making for patients with complex coronary artery disease.
Selection of the appropriate administered activity for each patient's body habitus is very important to obtain diagnostic image quality. Current SPECT imaging guidelines suggest "…an effort to tailor the administered activity to the patient's habitus and imaging equipment should be made… [however] strong evidence supporting one particular weight-based dosing scheme does not exist." An increase in body weight leads to higher fractions of attenuated and scattered photons, resulting in lower quality PET images for a given injected activity. Weight-based tracer dosing is commonly recommended as a solution in whole-body PET imaging with F-18-FDG. In contrast, Rb-82 PET imaging has traditionally been performed using a single dose (e.g. 40 mCi) administered for all patients but this is known to result in lower count-density and image quality in larger patients. This effect can be mitigated to some degree by administration of Rb-82 activity as a proportion of body weight while maintaining accuracy for the detection of disease. The objective of this project is to determine whether Rb-82 activity administered as a squared function of patient weight (quadratic dosing) can standardize PET myocardial perfusion image quality over a wide range of body weights. Sequential patients referred for dipyridamole stress Rb-82 PET perfusion imaging at the University of Ottawa Heart Institute. Patients will be divided into 4 weight groups to determine if there are significance differences in image quality or accuracy of injected Rb-82 activity between patients. Twelve (12) patients will be recruited in each of the 4 weight groups (3 in each 10 kg interval) to uniformly sample the full range of patient weights from 30 to 190 kg. Based on the previous oncology PET literature image quality is not expected to change as a function of weight, i.e. SNR and CNR will be proportional to weight0 (no weight-dependence) with quadratic dosing of Rb-82. Two operators will perform the PET image analysis as described above.
The DESyne BDS Plus Randomized Clinical Study is a prospective, multi-center, single blind, randomized clinical study. Randomization (1:1; DESyne BDS Plus : DESyne X2) of up to 100 patients (50 in each arm) requiring treatment of up to two de novo coronary artery lesions ≤ 34 mm in length in vessels ≥ 2.25 mm and ≤ 3.5 mm in diameter will be conducted. Clinical endpoints will be assessed at each follow-up point: 3 days or hospital discharge (whichever comes first), 1, 6, and 12 months.
This is a single-center, prospective, controlled and diagnostic clinical trial which will enroll 30 patients scheduled for coronary angiography in China.Patients will receive contrast-enhanced cardiac magnetic resonance with polysaccharide superparamagnetic iron oxide nanoparticle before percutaneous coronary angiography.In order to evaluate the safety of polysaccharide superparamagnetic iron oxide nanoparticle, patients will detect iron levels in peripheral and tissue before and after the examination.The main indicators of the study are the degree of coronary artery stenosis and the stability of coronary atherosclerotic plaque assessed by contrast-enhanced cardiac magnetic resonance with polysaccharide superparamagnetic iron oxide nanoparticle.
Open-label, randomized, cross-over study conducted in a single center, applied to patients receiving a polypill with 100 mg of acetyl salicylic acid and different doses of ramipril and atorvastatin for indication of secondary prevention according to clinical practice, with objective of analyzing the level of systolic blood pressure and LDL-cholesterol in the same patient in 2 different periods: one under treatment of 3 months with the polypill and another of 3 months with the components separately.
PROTEUS is a multicentre, two arm, randomised controlled trial of a medical device to assess the impact of the introduction of EchoGo into the standard care pathway for stress echocardiology.
