22 Clinical Trials for Various Conditions
The focus of this secondary data analysis is to determine whether pain due to a combination of both cardiac and non cardiac sources operates as a mediator of behavior change, an area that has not been previously evaluated.
We are interested in achieving an empirical test of the two intervention approaches under study. Specifically, we seek to determine the potential differential impact of positive affect induction and self affirmation following the qualitative study phase.
The long-term objective of this study is to determine whether a positive affect and self-affirmation condition added to an empirically demonstrated approach for motivating behavior change is more effective than a standard approach in reducing risk factor behavior among a high-risk group of patients with coronary artery disease. Thus, the goal of the project is to refine and improve strategies for long-term maintenance of physical activity among patients post-angioplasty or stent.
To explore and illuminate the cultural, social, and psychological factors that either facilitate or serve as barriers to behavioral change in angioplasty patients. Through a series of open-ended questions we will explore and build a better understanding of how culturally different patient groups perceive heart disease and the difficulties in changing health behavior. In addition, we hope to better understand and anticipate barriers and issues that participants face in successfully changing their behaviors.
The research study is designed to assess the technical feasibility and safety of a perivascular injection of vonapanitase delivered via micro-infusion catheter to the distal popliteal, tibial or peroneal arteries immediately following successful angioplasty.
The purpose of this study is to determine if it is safe and feasible to apply PRT-201 to the adventitia of arteries following successful angioplasty (PTA).
This was a Phase 2a prospective, single center, randomized, double-blind, placebo-controlled study designed to assess the efficacy, pharmacokinetics, safety and tolerability of IV elamipretide for reduction of reperfusion injury in subjects with Atherosclerotic Renal Artery Stenosis (ARAS), who are undergoing percutaneous transluminal angioplasty of the renal artery (PTRA).
AIR STUDY TITLE: Anti-Ischemic effects of Abciximab(Reopro) PATIENT POPULATION: Patients undergoing PCI(an interventional procedure placing a small stent/metallic tube to keep a narrowed artery in your heart open) and either on a stable statin dose or not on a statin. Statin= cholesterol lowering drug(ie, lipitor, zocor). INTERVENTION: Heparin vs. heparin + abciximab during PCI PURPOSE: Measure the effects of abciximab on special healing blood stem cells (EPC's-Endothelial Progenitor Cells), on inflammation, on oxidative stress and on microvascular blood flow. PATIENT ASSESSMENT: 1. 50ccs blood draw on day 1(from sheath), day 2 ,day 7 and day 28. 2. Measurement of blood flow in selected suitable patients 3. 10 minute questionnaire before discharge and on visit on day 28.
This study is a randomized, double-blind, multi-center study designed to compare differences in rates of myonecrosis (measured as an elevation of CK-MB ratio ≥ 2 times ULN) within 24 hours following low-medium risk percutaneous coronary intervention (PCI) in aspirin or clopidogrel non-responsive patients who are randomized to heparin with or without eptifibatide therapy during PCI. The primary objective of this study is to determine if the use of eptifibatide is associated with a significant difference in post-PCI myonecrosis (measured as an elevation of CK-MB ratio ≥ 2 times upper limit of normal \[ULN\]) within 24 hours of low-medium risk PCI in patients who are aspirin or non-responsive as determined by VerifyNow Aspirin and P2Y12 testing.
The primary objective of this study is to assess the outcomes of stenting with distal protection in the treatment of obstructive carotid artery disease. The devices to be utilized are the Cordis PRECISE® Nitinol Stent Systems (5.5F and 6F) and the Cordis ANGIOGUARD™ XP Emboli Capture Guidewire (ECGW).
This study will examine the use of magnetic resonance imaging (MRI) in detecting blood vessel inflammation. The results of this study may later be applied to diagnosing inflammation of arteries in patients with atherosclerosis, predicting disease progression in these patients, and guiding therapy. Patients with peripheral artery disease (for example, blockage of a leg artery) undergoing balloon angioplasty at Suburban Hospital in Bethesda, Maryland, may be eligible to participate in this study. Because this procedure, which opens blocked arteries, can cause inflammation in the vessel wall, it affords an opportunity for studying MRI detection of such inflammation. Study candidates will be screened with a medical history and physical examination. Participants will have a MRI scan and blood drawn at Suburban Hospital before the angioplasty and again either 1 to 3 days or 2 weeks after the procedure. Before the MRI scan is begun, a catheter (a thin plastic tube) is inserted in an arm vein and 90 milliliters (about 3 ounces) of blood is drawn. The patient then lies on a table that slides into the MRI scanner-a large donut-shaped machine with a magnetic field. A flexible, padded sensor called an MRI coil is placed over the area to be imaged; this device is used to improve the quality of the pictures. During the scan a contrast material called gadolinium is injected through the catheter. Gadolinium brightens the image of the blood vessels. The procedure lasts up to 2 hours.
The objective of this study is to evaluate acute device and technical success of the CGuard Prime™ Carotid Stent System (80cm) when used in conjunction with the Enroute NPS during Transcarotid Artery Revascularization procedures in the treatment of carotid artery stenosis in spatients at high risk for adverse events from carotid endarterectomy.
The use of drug coated balloon (DCB) in patients with critical limb ischemia (CLI) and tissue loss has recently raised some concerns after the IN.PACT deep trial using paclitaxel coated balloon angioplasty in the tibial arteries was terminated. The investigators objective is to establish the safety and efficacy of drug coated balloon (DCB) for femoropopliteal occlusive disease in patients with critical limb ischemia (CLI) and tissue loss. The investigators objective is to establish the safety and efficacy of drug coated balloon (DCB) for femoropopliteal occlusive disease in patients with critical limb ischemia (CLI) and tissue loss.
The guideline-recommended standard of care for patients who have experienced a heart attack, heart failure, or other coronary event or procedure is exercise-based cardiac rehabilitation (CR). Despite proven benefits, traditional CR is severely underutilized. Moreover, what is typically lacking from traditional CR programs is effective psychosocial risk management. This represents a critical gap in care given the well-documented psychosocial needs of this patient population.The objective of this feasibility study is to conduct a pilot randomized controlled trial (RCT) of Mindfulness-Based Stress Reduction (MBSR) versus usual care in CR-eligible cardiac patients. Randomization will be stratified within two strata based on participation in CR (yes/no) among CR-eligible patients. The primary goals of this pilot study are to: 1) obtain estimates of treatment effects and variability; 2) evaluate recruitment and retention strategies; and 3) examine the safety of the MBSR protocol in CR-eligible patients.
The primary objective of the study is to collect confirmatory data supporting the safety and effectiveness of SSO2 Therapy in treatment of anterior acute myocardial infarction (AMI) patients who have undergone successful percutaneous coronary intervention (PCI) with stenting within six hours of experiencing AMI symptoms.
The ABSORB III PK sub-study is a prospective, open-label, non-blinded study enrolling approximately 12 subjects in up to 5 US sites. ABSORB III PK sub-study is a part of ABSORB III RCT (NCT01751906). The objective is to determine the pharmacokinetics of everolimus delivered by the Absorb BVS in a separate and non-randomized cohort of subjects who only receive Absorb BVS with a maximum of two de novo native coronary artery lesions after implantation of the Absorb BVS. Note: The ABSORB III PK subjects will not contribute to the determination of the ABSORB III RCT primary endpoint.
The proposed study is a registry of patients treated with primary angioplasty for acute myocardial infarction. The aim of this registry is to define the outcomes of patients treated for acute, ST-segment myocardial infarction (STEMI) at community hospitals without on-site cardiac surgery programs that have completed the Cardiovascular Patient Outcomes and Research Team (C-PORT) Primary Angioplasty Development program. The primary medical outcome for the registry is the combined incidence of death, recurrent non-fatal myocardial infarction and stroke.
The purpose of this study is to determine if testing patients for endothelial dysfunction will help identify which patients are more likely at risk to have another heart attack in the future. Study participants will undergo mental stress testing while at the same time being connected to a device that measures endothelial function via the Endopat device. These same participants will also undergo a sleep study via the Watchpat device.
The study investigates the safety and efficacy of PMX-60056 for the Reversal of Heparin in Patients Undergoing Percutaneous Coronary Intervention (PCI)
