This is a prospective, randomized, controlled, multicenter, open-label study designed to assess whether Pd/Pa is non-inferior to FFR when used to guide treatment of intermediate coronary artery stenosis
Recommendations for cardiovascular rehabilitation (CVR) encourage exercise training, primarily involving the aerobic system, to allow patients to regain independence in daily activities. However, the lactic anaerobic process is also involved during these activities (stair climbing, carrying loads, etc.). Hence there is a major interest in accurately assessing patients' anaerobic capacities in order to tailor suitable exercise programs. However, there are no functional tests specifically dedicated to the evaluation of lactic anaerobic metabolism and adapted to people with coronary disease. The investigators offer a dedicated test, the short and fast test (SFST), which can be applied in current clinical practice and has already been evaluated in a population of healthy subjects. The purpose of this project is to evaluate the safety, feasibility and validity of SFST in a population of patients with coronary artery disease.
The CATH-VR study will investigate the effect of virtual reality (VR) on patient pain, anxiety, and radial artery vasospasm during coronary angiography. Our hypothesis is that the use of VR will decrease patient anxiety and pain via validated scoring systems, as well as show a low rate of vasospasm of the radial artery. In addition, we hypothesize that the amount of opioid and benzodiazepine medications utilized for procedural sedation will be lower in the intervention arm. VR has gained recent attraction as an alternative or adjunctive treatment option for pain, but its effect on reducing procedural sedation has not been studied. We propose a single center, randomized control pilot study to further investigate. The patient population will include adults older than 18 years who present for outpatient diagnostic coronary angiography.
Polymorphisms of the cytochrome P450 (CYP) 2C19 enzyme has been consistently shown to modulate clopidogrel response. Accordingly, the Food and Drug Administration (FDA) has issued a warning on the potential for reduced efficacy of clopidogrel among carriers of loss-of-function alleles (LOF) for CYP2C19 and suggest considering alternative antiplatelet therapies for these individuals. The pharmacodynamic (PD) effects of prasugrel and ticagrelor are not affected by CYP2C19 genetic polymorphisms. However, to date there are no head-to-head PD comparisons between these agents among patients with different CYP2C19 genetic polymorphisms, which is currently under investigation in CAD patients undergoing PCI at UF Health-Jacksonville (UFJ 2014-12, NCT 02065479). In order to rule out play of chance findings, pharmacogenetic investigations require external validation cohorts to support the study findings. Therefore, the present randomized study is designed to serve as an external validation cohort conducted in patients with established CAD not undergoing PCI testing the non-inferiority in platelet reactivity of prasugrel versus ticagrelor among CYP2C19 LOF allele carriers.
In systemic lupus erythematosus (SLE), cardiac manifestations, e.g. coronary artery disease (CAD) and myocarditis are leading causes of morbidity and mortality. The prevalence of subclinical heart disease in SLE is unknown. We studied whether a comprehensive cardiovascular magnetic resonance (CMR) protocol may be useful for early diagnosis of heart disease in SLE patients without known CAD
The objective of this prospective, multicenter, randomized, open-label trial is to evaluate the completeness of stent expansion following a strategy of lesion preparation with either a Super High-Pressure NC PTCA Balloon (OPN NC) or a Scoring PTCA Balloon (NSE Alpha) after unsuccessful lesion preparation with conventional NC balloon angioplasty in an angiographically well-defined group of patients with severely calcified coronary lesions (grade 3) undergoing coronary stent implantation (SYNERGY everolimus-eluting stent (EES)).
The rationale of MIDA trial is to determine efficacy and tolerability of ranolazine molecule among Pakistan population and obtain firsthand knowledge about the molecule ranolazine.
This is a prospective, exploratory, randomised clinical trial. Patients with diagnosed cancer that are to be treated with 5-fluorouracil (5-FU) will be randomised into standard oncological treatment or a cardiological assessment prior to the 5-FU treatment. The investigators hypothesize that aggressive management of ischemic risk factors in asymptomatic patients will reduce the number of hospitalisations and investigations for acute coronary syndrome during and after 5-FU treatment and that patients with high coronary artery calcium scores are more likely to experience chest pain during the treatment with 5-FU.
A Phase 2, Randomized, Double-Blind, Placebo-Controlled, Safety and Efficacy Study of Dutogliptin in Combination with Filgrastim in Early Recovery Post-Myocardial Infarction
This study compares angiographic and clinical outcomes in patients with long coronary lesions treated with sirolimus-eluting stent (Ultimaster stent) or everolimus-eluting stent (Xience Alpine stent). The study uses a randomized, multicenter, controlled design approach.
