The purpose of this study is get to know what and how Xinyuan capsule in hospital results in drug-induced liver injury or adverse drug reactions from a cohort event monitoring as registration research.
The purpose of this study is to make a cohort event monitoring to see whether and how Dazhuhongjingtian injection in hospital results in adverse events or adverse drug reactions
This study builds, in part, upon preliminary results generated as part of the Pharmacogenomics Anti-Platelet Intervention (PAPI) Study (NCT00799396). The purpose of this investigation is to assess the impact of genetic variation in the carboxylesterase 1 (CES1) on response to clopidogrel as well as dual antiplatelet therapy (i.e. clopidogrel and aspirin), as assessed by ex vivo platelet aggregometry, in healthy Amish individuals. The investigators hypothesize that participants who carry alleles that modify the activity or expression of CES1 will have altered response to clopidogrel as well as dual antiplatelet therapy.
To determine whether, in a population of patients presenting to the rapid access chest pain clinic (RACPC), routine FFRct (Fractional Flow Reserve Computed Tomography) as a default test is superior in terms of resource utilisation when compared to routine clinical pathway algorithms recommended by the National Institute for Health and Care Excellence (NICE)
Most previous trials support the absolute increase in bleeding risk with perioperative administration of antiplatelet. Furthermore, recent studies demonstrated that perioperative major bleeding may be related to increase cardiovascular risk. The investigators will compare the efficacy and safety of continuing versus stopping antiplatelet therapy during perioperative period in patients underwent PCI(Percutaneous Coronary Intervention) with next generation DES(Drug Eluting Stent).
This is a single-center double blind, placebo controlled study of patients undergoing a cardiac catheterization where the need for a percutaneous coronary intervention (PCI) is anticipated or will be determined during the early diagnostic phase. The study will assess the use of intracoronary nicardipine vs. sterile saline injection in reducing the index measurement of microcirculatory resistance (IMR). Fifty consecutive patients presenting to the Thomas Jefferson University (TJUH) Cardiac Catheterization lab will be randomized in a 1:1 fashion to receive either intracoronary nicardipine or sterile saline injection prior to PCI. IMR values will be assessed pre and post procedure. Data on clinical outcomes and adverse events will be collected by phone at 30 days and 1 year following the procedure.
Investigator-initiated, international, multicentre, observational study with two cohorts. The two study cohorts will be: Cohort A: to understand if the local blood flow patterns (associated with low WSS), as evaluated by computational fluid dynamic tools from combined angiographic and OCT invasive images, may better predict the clinical outcome of patients with bifurcated coronary lesions treated by PCI. Cohort B: to understand if the local blood flow patterns (associated with low WSS), as evaluated by computational fluid dynamic tools from combined angiographic and OCT invasive images, may better predict the clinical outcome of patients with sub-critical bifurcated lesions managed conservatively. Coronary angiography and OCT images will be combined to obtain a three-dimensional model of the diseased coronary vessels that will be used to calculate the local blood flow patterns and the time-averaged WSS at the bifurcated lesion level by using computational fluid dynamics software. Baseline (in patients both managed conservatively and treated by PCI) and post-PCI (in patients treated by PCI) images will be processed.
Patients with cardiac disease have been shown to have deficits in activities such as standing up from a chair. The Biodex Sit2Stand Trainer is a new device meant to improve sit to stand performance by providing a lifting force through the seat to help the individual stand. The amount of lift can be graded to help improve leg strength, endurance, and function over time. The device has the potential to be a form of training for those in cardiac rehabilitation who have limitations in standing from a chair.
The aim of this prospective, open-label, randomized, single center study is to compare the effect of usual dose rosuvastatin plus ezetimibe and high-dose rosuvastatin on modifying atherosclerotic plaque.
The primary objective of this trial is to compare the safety and efficacy of the SINOMED BuMA Supreme biodegradable coronary stent in patients with up to 3 coronary lesions to either the XIENCE or Promus durable polymer coronary stents. This prospective, global, multi-center, randomized 2:1, single blind study will enroll up to 1632 subjects at up to 130 investigational sites in North America, Japan, and Europe. Subjects will have clinical follow-up in-hospital and at 30 days, 6 months, 12 months, and 2, 3, 4, and 5 years.
