Filter by:We aim to investigate the efficacy of N-acetylcysteine (NAC) to attenuate acute renal dysfunction in patients with rheumatic valvular heart disease undergoing single valve replacement.
Minimally invasive revascularization of the left anterior descending artery followed by stent implantation versus percutaneous coronary intervention or coronary artery bypass in patients with multi-vessel coronary disease
The purpose of this study is to test whether a culturally sensitive self-management (SM) intervention, compared to an education only control, will reduce all-cause hospital days in patients with mild to moderate heart failure and household income less than $30,000 per year.
The purpose of this study is to determine the average risk for thyroid irradiation for any type of paediatric cardiac catheterization, based on the cummulative at-risk dose of 100 mSv, adjusted to the measured thyroid volume and to the patient's age.
The Environmental Polymorphisms Registry (EPR) Health and Exposure Survey is designed to gather health, family history of disease, environmental exposures and lifestyle data on adult EPR subjects. The EPR is a registry established to collect and store DNA samples from 20,000 volunteers from North Carolina and to serve as a resource to scientist investigating genotype-driven translational research of chronic conditions. Under this new protocol, we will administer a health and exposures survey to all EPR subjects. The information collected in the survey will be used to better characterize the EPR population thus making it more useful to NIEHS researchers. The survey contains approximately 200 questions. Data from the survey will help researchers develop hypotheses, design follow-up studies, and select appropriate subjects. The survey will be administered to EPR subjects using a modified version of the Dillman Total Design Method (TDM) for surveys. This method requires following specific time-dependent steps for survey administration that incorporate both self- and phone administration and other types of phone and mail contact. The goal of TDM is to maximize subject response rates.
This study will be a retrospective study. The patient data from the electronic medical records and existing database will be collected and analyzed. Primary endpoints will be postoperative mortality (within 30 days) and overall complications and length of hospital stay. The secondary endpoints will be myocardial infarction, cardiac death, CHF, arrhythmia, ischemia, stroke, neurological complications, length of ICU stay, re-admission rate, infections, pulmonary complications, length of intubation time, length of ventilation time, and acute renal failure.
The study is designed to assess the effect of statin on atherosclesrosis progression as well as to explore its potential mechanism besides lipid modifying , such as effect on inflammation and vascular calcification.
The purpose of the study is to demonstrate that Custodiol-HTK is not inferior to cold cardioplegic solution in patients undergoing cardiovascular surgery requiring cardioplegic arrest.
Congenital heart disease with need for early surgery in newborns is associated with an increased incidence in global impairment in development. The causes of these late adverse neurologic outcomes are multifactoral and include both fixed (or patient-specific factors) and modifiable factors. They relate to both the mechanism of central nervous system injury associated with congenital heart disease and its treatment. Measuring cerebral oxygenation is a promising non-invasive way of cerebral monitoring in a neonatal intensive care unit. The importance of cerebral monitoring in neonates with congenital heart problems at risk of developing neurological complications is increasingly recognized. In this way the most vulnerable moments for the newborn brain can be detected and ,if possible, lead to change in (timing of) treatment.
Turner syndrome is a congenital complete or partial lack one of the female sex chromosomes affecting 1 of 2000 live born girls. The syndrome is characterized by an increased prevalence of ischemic heart disease, aortic dilation and dissection, hypertension, stroke and autoimmune diseases in general. Our study aim is: - Using MRI to further characterize and find risk factors leading to aortic dilation. - Using MRI to assess the degree of aortic distensibility. - Using Computed tomography x-ray scanning of the heart and coronary arteries to characterize the prevalence and degree of ischemic heart disease and coronary anomalies. - Using pressure sensitive ultrasound (applanation tonometry) to assess the degree of aortic stiffness when compared to controls using end points as Pulse Wave Velocity, Augmentation Index and Central Pulse Pressure.
