NCT01754064
SCORE is an active, prospective, non-randomized, multi-center outcome-oriented registry of patients implanted with St Jude Medical (SJM) market-released cardiac rhythm management (CRM) products. This registry will be conducted in the United States (US). The primary purpose of the registry is to evaluate and publish acute and long-term performance of market-released SJM CRM products by analyzing product survival probabilities. Product status and any related adverse events will be collected to measure survival probabilities.
NCT00027170
This study will explore new ways of using magnetic resonance imaging (MRI) to evaluate the heart and blood vessels of patients with cardiovascular disease, including better detection of myocardial infarction (heart attack) and blockage of heart and leg arteries. Patients 18 years of age and older with cardiovascular disease may be eligible for this study. All participants will have magnetic resonance imaging of the heart. MRI uses a magnetic field and radio waves to show structural and chemical changes in tissues. For the procedure, the patient lies on a table surrounded by a metal cylinder (the scanner). A 'gadolinium contrast' material may be injected into the patient s vein during part of the study to brighten the images. Patients wear earplugs during the scan to muffle loud knocking sounds caused by the electrical switching of the magnetic fields. They will be asked to hold their breath intermittently for 5 to 20 seconds during the scan. They will be monitored with an electrocardiogram (EKG) during the procedure and will be in contact by intercom at all times with the person performing the scan. Patients can request to stop the study and come out of the scanner at any time. The procedure may last from 30 to 90 minutes. An echocardiogram a test that uses sound waves to produce pictures of the heart and blood vessels-may be done to confirm the MRI findings. In addition, patients may undergo one or more of the following optional studies: * Dobutamine stress MRI - This test uses dobutamine-a medicine that simulates exercise by increasing heart rate and heart function-to detect blockages in the coronary arteries (vessels that supply oxygen and nutrients to the heart) and locate areas of the heart that are permanently damaged, perhaps by a previous heart attack. For this test, MRI pictures of the heart are taken before, during and after administration of dobutamine. Gadolinium may be injected during part of the study to brighten the images. An EKG will be used to monitor the heart during the procedure. * Vasodilator MRI - The procedure and objectives of this test are the same as those described for dobutamine stress MRI, except that this study uses dipyridamole or adenosine. These drugs dilate blood vessels, causing increased blood flow to the heart. * Plethysmography MRI - This test determines the presence and severity of narrowing in arteries that supply blood to the leg. Blockage of these vessels often causes pain while walking. This study will compare plethysmography MRI with venous occlusion plethysmography, an older method of measuring blood flow in the legs. For venous occlusion plethysmography, a large blood pressure cuff is placed around the upper leg and a strain gauge (thin elastic band) is placed around the calf. The pressure cuff is inflated very tightly for 5 minutes to block blood flow to the leg, and another pressure cuff over the ankle is also inflated. When the large cuff is deflated, blood rushes to the leg, a smaller cuff is inflated to a low pressure, and the strain gauge measures the maximum blood flow to the leg for 1 or 2 more minutes. This procedure is done once or twice outside the MRI scanner and once or twice inside the scanner. The scans are performed as described above for the dobutamine and vasodilator studies. The strain gauge is not used for plethysmography MRI the MRI pictures are used to measure flow.
NCT01830062
The aim of this study is to compare the relationship between the coronary artery calcification assessed by MDCT with the plaque characteristics and necrotic lipid core content of non-intervened coronary segments assessed with near infrared spectroscopy (NIRS) in patients with symptomatic coronary artery disease (CAD).
NCT02290028
The QP ExCELs study is designed to confirm safety and efficacy of the BIOTRONIK Sentus OTW QP left ventricular leads to satisfy FDA requirements for regulatory approval of the leads in the US. The Sentus OTW QP leads received FDA approval on May 4, 2017. Long-term safety of the BIOTRONIK Sentus OTW QP left ventricular leads will be confirmed during the ongoing post approval phase (US sites only). A protocol update was implemented on September 6, 2019 to transition the long-term follow up for the ongoing Sentus QP Study to a new EP PASSION real-world data methodology.
NCT04133350
This is a prospective, single-arm, unblinded pilot study and registry that aims to demonstrate adherence to adaptive servo-ventilation (ASV) therapy in patients with moderate to severe sleep disordered breathing who have been recently hospitalized. ASV therapy has been linked to improved outcomes in this population, but adherence to therapy is low. The AirCurve 10 ASV device that will be used for this study employs newer technologies, such as web-based monitoring and provides patients feedback, which may increase therapy adherence and therefore improve patient outcomes.
NCT02026466
This is an observational registry, sponsored by Saint Luke's Hospital. This study is to be conducted according to DHHS Guidelines, applicable state regulations, and local IRB policies and procedures. The overall objective is to address current gaps in knowledge regarding CTO-PCI, as a prospective, multi-center, single-arm study of 1,000 participants.
NCT03350542
EVOLVE 48 is a prospective, open label, single arm, multi-center trial. The purpose of this study is to assess the FDA requirement for safety and effectiveness of the SYNERGY 48 mm Coronary Stent System for the treatment of subjects with atherosclerotic lesion(s) \> 34 mm and ≤ 44 mm in length (by visual estimate) in native coronary arteries ≥2.5 mm to ≤4.0 mm in diameter (by visual estimate).
NCT04325191
Increased dietary sodium causes increases in oxidative stress and damages blood vessels. Americans eat more than the recommended amount of sodium. Melatonin is a powerful endogenous antioxidant that has reduced oxidative stress levels in clinical and healthy populations. This study will investigate whether melatonin can attenuate the negative effects of sodium on blood vessels.
