Filter by:The objective of this study is to evaluate feasibility, safety and effectiveness of the first generation transfemoral JenaValve Pericardial TAVR System (formerly named JenaValve TAVI Plus System- Transfemoral) in an elderly patient population with severe aortic stenosis who are at high risk for surgical aortic valve replacement.
Cardiovascular disease (CVD) is the leading cause of death worldwide. Most individuals with CVD show no evidence of disease for decades as the disease progresses before the first onset of symptoms, often a "sudden" heart attack, finally arises. The spatial repolarization heterogeneity within the ventricular myocardium had been proposed to represent the function of the heart in health and disease. Greater than normal levels of repolarization dispersion may allow early diagnosis of CVD. There is a growing interest in the characteristic features of ventricular repolarization that leads to lethal ventricular arrhythmia even with the use of non-antiarrhythmic drugs. The recovery time dispersion may reflect a repolarization heterogeneity leading to lethal ventricular arrhythmia. Previously, the investigators had utilized a 64-channel low-TC SQUID MCG device to develop and verify 2 parameters, so called smooth index of QTc (SIQTc) and T wave propagation (TWP), to accurately detect and localize the myocardial ischemia. Recently Nakai, et al. reported that a newly developed 187-ch signal-averaged vector-projected ECG (187-ch SAVP-ECG) could evaluate low-amplitude high-frequency potentials and repolarization heterogeneity. In this project, the investigators'll try to modify and improve the spatial resolution of ECG signals from a Self-built-in multichannel ECG system with a newly developed algorithm, and also try to derive the SIQTc and TWP from this system, for early detection of CVD. The investigators intend to prove the concept that this newly developed multichannel ECG system could efficiently detect or diagnose CVD with acceptable sensitivity and specificity, and in a portable way.
The question this research project wants to explore is whether using the Prevena Incision Management System (Prevena) will improve sternal wound edge oxygenation in patients undergoing Coronary Artery bypass surgery with Bilateral Internal Mammary Artery grafts.
The SYNTAX III Revolution trial is a randomized diagnostic research study that investigates the use of CT scan and angiogram of the heart to help doctors decide which method is the best to improve blood supply to the heart in patients with complex coronary artery disease. Each patient will undergo an angiogram and CT scan per standard of care. The randomization strategy in this study is not between patients but between two teams of doctors, the so-called "Heart Teams", will be randomized: in the first round, team 1 assesses the angiogram, and team 2 assesses the CT scan. Then they make a decision about which treatment would be the best to treat complex coronary artery disease. In the second round, both teams see the imaging method that they did not see in the first round, and make the decision again. The final decision on the clinical treatment strategy is at the sole discretion of the Heart Team and there are no criteria described in SYNTAXIII Revolution protocol leading influencing this final decision. Hypothesis: Determination of the best treatment strategy for coronary artery disease based on a CT scan will result in similar decisions as based on invasive coronary angiography.
A pilot program was created by the network's primary care leadership team at Massachusetts General Hospital. A population health management program was implemented for chronic disease management. The investigators evaluated quality of care process and outcome measures over the first six months of the program and compared practices assigned a central population health coordinator to those not assigned this support.
This study will investigate whether small changes (nudges) made in a cafeteria, where participants eat for 4 weeks, can improve their food behavior and health during the 4 weeks, and 6 weeks and 6 months after their stay. Half the participants will be exposed to one of four types of nudges (focused on reducing salt intake, increasing vegetable intake, reducing portion size, and a combination of these nudges), and half of the participants will eat in the cafeteria as it is currently, without modifications.
Twitter use is surprisingly well represented across broad demographic population segments and health-related messages. The promise of using Twitter is that its use is growing rapidly, it allows the investigators to view communications that were impossible to intercept before, and it potentially provides information faster and less expensively than collection from other media channels. Prior work also supports that social media interventions can improve health behavior change (e.g. weight loss, physical activity) and outcomes.The overarching goals of this proposal are to understand the uses and limitations of this communication channel to improve patients' ability to manage their CV health condition.
The Global CMR Registry aims to promote collaboration of CMR sites worldwide in setting imaging and reporting standards, assessing its diagnostic impact on patient care, and determining the cost-effectiveness of CMR imaging. It will be the largest collective body of evidence reflecting the current clinical applications in patient care, which healthcare payers and governing bodies alike can depend on when metrics such as testing appropriateness, common indications, and diagnostic effectiveness are called for. It will also be able to reflect any changes in patient impact from CMR over time as technical development evolves. Furthermore, it will allow an assessment of improvements in diagnostic and therapeutic thinking, risk stratification, and cost-effectiveness relevant to current patient management.
This project will look to improve standards of care for diabetic patients by evaluating a program that supports participants in making healthy lifestyle changes. The program consists of 13 educational sessions that contain information about the prevention and care of diabetes and cardiovascular disease, physical activity, nutrition, community health and emotional well being.
Hypothesis: In addition to the liver deleterious effects, Chronic Hepatitis C (CHC) can cause changes in other organs highlighting the increased cardiovascular risk (CVR) through accelerated atherosclerosis, whose consequences may persist even after healing infection with new antiviral treatments. This can have major impact on the health system. Obtaining a Sustained Virological Response (SVR) with a free Interferon (IFN) antiviral treatment is probably able to reverse, at least partially, increased vascular risk induced by Hepatitis C virus (HCV) and perhaps ultimately reverse the subclinical atherosclerosis. Aims: To study the presence of early-subclinical atherosclerotic disease (endothelial dysfunction and subclinical atherosclerosis) in patients with CHC and evaluate the influence of treatment in the short and medium term on the CVR derived. Studying these same issues but in patients with established atherosclerotic disease.
