Filter by:Different approaches to cardio-neuroablation (CNA) to treat neurally mediated syncope, sinus node dysfunction, and functional atrioventricular block have been published. Investigators have developed a more limited and specific approach of CNA, called cardio-neuromodulation (CardNM). This treatment is based on a tailored vagolysis of the sinoatrial node through partial ablation of the anterior right ganglionated plexus (ARGP); it is also based on an innovative anatomic strategy. The feasibility of CardNM has already been tested in our center in a limited first study in humans (CardNMH1), with a favorable outcome for the patients involved. The results of CardNMH1 have been submitted for publication. The purpose of this second study of CardNM in humans (CardNMH2) is to collect more procedural and clinical data in well-defined patient groups.
This is a study of the perfusion of the myocardium in adults with specific forms of repaired congenital heart disease using established cardiac MRI techniques and correlating perfusion with clinical outcomes.
To develop and validate the noninvasive measurement of MBF and MFR by using dynamic imaging with a CZT camera, and evaluate the diagnostic and prognostic implications in various heart disease.
This is a randomized controlled trial of the feasibility and utility of implementing a smartphone application (MVN) to maintain compliance with a Heart Healthy lifestyle after discharge from a cardiac outpatient rehabilitation program. Patients will be randomized into one of two groups: usual care (control: UC) or Movn mobile application (intervention: MVN). This study will improve and strengthen data collection from this at-risk patient population by recording baseline clinical and psycho social measures while gaining insight into self-reporting of physical activity and frequency between the UC and MVN groups.
The outcome predictors for cardiac surgery has been popular for many researchers and clinicians. Determining risk factors before surgery reduce morbidity and mortality after surgery. Some routine blood results have been used as predictors for cardiac surgery but none of the researches studied red cell distribution width, mean platelet volume, platelet/lymphocyte ratio and neutrophil/lymphocyte ratio. This study focused on these parameters and to see whether these parameters can be predictors for cardiac surgery.
This study aimed to compare 2 activated clotting time analysers (Hemochron Jr vs. ACT Plus).
French study, multicentrique with the cooperation of several hospital centers . 700 patients (200 in the stage 1 and 500 in the stage 2). Every patient will complete questionnaires in a anonymous way.
Cardiac output (CO) is an important parameter in the diagnosis and therapy of cardiac diseases. The aim of the study at hand was to evaluate NICOM (bioreactance) as a new method for determinion of CO and to compare it to Innocor (inert gas rebreathing), which previously showed promising results.
Cardiac output (CO) is an important parameter in the diagnosis and therapy of cardiac diseases. The current standard methods for the determination of CO, however, are either invasive (e.g. right heart catheterization) or technically expendable and expensive (magnetic resonance tomography, MRT). Therefore, the aim of the study at hand was to evaluate NICOM (bioreactance) as a new method for determinion of CO and to compare this new technique to MRT.
Environmental toxins exert damaging health effects in workers. Thousands of responders who worked or volunteered on the World Trade Center (WTC) rescue and recovery effort following the September 11, 2001 attacks suffer from health conditions or may be at increased risk for worsening health. In a pilot study, investigators identified the first evidence of kidney damage in subjects with very high exposure at Ground Zero. Specifically, noted was a preliminary association between the intensity of particulate matter exposure and albuminuria, a marker of early chronic kidney disease (CKD), systemic endothelial dysfunction, and increased cardiovascular risk. The long-term goal is to minimize the risk of CKD and cardiovascular disease (CVD) among individuals exposed to inhaled toxins. The primary objective of this research is to quantify the risk of kidney damage among first responders to the WTC attack and to determine the relationship to particulate matter exposure as well as determine an association between renal and cardiovascular damage in first responders and to explore potential mechanisms. The central hypothesis is that exposure to inhaled particulate matter causes systemic inflammation and endothelial dysfunction that result in chronic kidney and cardiovascular damage. This hypothesis will be investigated in a subgroup of participants from a previously conducted NIOSH-funded study "Pulmonary Function Abnormalities, Diastolic Dysfunction and WTC Exposure: Implications for Diagnosis and Treatment" ("WTC-CHEST," PI Mary Ann McLaughlin). The proposed study will capitalize on unique resources in WTC-CHEST, including the standardized collection of data on particulate matter exposure and shared risk factors for CKD and cardiovascular disease, and cardiopulmonary function testing. The output from this proposal is anticipated to have a broad impact on understanding the health effects of inhaled particulate matter.
