Filter by:The objective of this study is to reduce the incidence of postoperative delirium after cardiac surgery in the elderly patient. This proposal is a clinical trial designed to reduce delirium in patients undergoing cardiac surgery by replacing standard postoperative sedation protocols (propofol, midazolam, opioids) with a new alpha2-adrenergic receptor agonist (dexmedetomidine) possessing sedative, analgesic, and antinociceptive properties. Resource utilization analysis will be performed to determine cost effectiveness of the new treatment modality.
In the present study the investigators test the hypothesis that the epidural anesthesia added on the general anesthesia is able to improve patient's outcome.
The purpose of this study is to determine whether long-term treatment with a beta-blocker (BB) such as atenolol and/or an angiotensin receptor blocker (ARB) such as telmisartan, given to adult patients with bicuspid aortic valve (BAV) disease (aortopathy) reduces the widening (dilatation) of the aorta from its baseline size.
Establishing new biochemical markers in the differential diagnostics and risk stratification in heterogeneous patient collectives is becoming more and more important. The markers should be objective, reliable, reproducible, quick and cost effective as well as specific and sensitive. Concerning the differential diagnostics of "dyspnea", NT-pro-BNP plays the most important role for the evaluation of a cardiac origin. However, a corresponding biochemical marker for pulmonary stress is lacking. The aim of the study at hand therefore was the evaluation of surfactant protein B in the differential diagnostics of pulmonary and cardiac diseases.
The purpose of this study is to identify cardiac patients' degree of unappreciated mild impairment in cognitive function patterns of cognitive function, and influencing factors related to cognitive functioning during hospitalization. The results from the study will contribute to tailoring the delivery of patient education to optimize patient understanding of information in future clinical practice. It is hypothesized that the study will demonstrate the following: 1. The degree of cognitive function for patients hospitalized in a CICU will be below the scores for normal functioning adults. 2. Patients with acute cardiovascular conditions will score differently in cognitive functioning at various times throughout their hospitalization. 3. Relationships between cognitive function and following variables: - Patients with greater sleep deprivation or fatigue will exhibit lower cognitive functioning. - Patients with greater hunger will exhibit lower cognitive functioning. - Patients who are experiencing greater anxiety will exhibit lower cognitive functioning. - Patients who are experiencing depression will exhibit lower cognitive functioning. - Patients who have undergone or will undergo shortly treatment or procedures will exhibit lower cognitive functioning.
The aim of this research is to apply cardiac tissue characterization in order to assess left ventricular function in cardiac surgical patients pre and post cardiopulmonary bypass. The procedures to be used include a retrospective review of transesophageal images obtained during conventional intraoperative transesophageal echocardiography (TEE) for cardiac surgery, as well as a secondary analysis with Tissue Doppler. The results will be compared with hemodynamic data obtained from a pulmonary artery catheter (PAC).
The accuracy of stress single photon emission computed tomography (SPECT) is limited by imaging artifacts, many of which are caused by soft tissue attenuation. A recent multicenter study performed by our laboratory comparing 7 commercially available attenuation correction (AC) camera systems in a cardiac phantom showed the best performance with the GE Hawkeye (a hybrid gamma camera-CT scanner) and the University of Michigan M-step (unique feature a camera orbit of 360˚ versus the usual 180˚) systems. In this study we will combine the strengths of these two systems (GE Hawkeye AC system and 360˚ camera orbit) to test the accuracy of this imaging system in a population of 400 consecutive patients undergoing clinically indicated stress SPECT. These patients will undergo SPECT imaging both with conventional methodology and the GE Hawkeye system. The conventional study will be interpreted and reported in the usual clinical fashion. The GE Hawkeye images will be interpreted independently by 2 observers blinded to the results of conventional imaging and will not be reported clinically. The primary study hypothesis is that AC will substantially reduce attenuation artifacts (mild fixed defects) without reducing the accuracy of either normal studies or myocardial infarction (MI). Clinical data and noninvasive test results (history of MI, electrocardiogram, and gated wall motion) will be used to distinguish defects which represent attenuation (false-positive) versus those due to MI (true-positive).
The aim of the study is to compare clinical management of patients with acute decompensation of heart failure, hospitalized in non cardiological ward, with the use of a mobile team including a cardiologist with portable echocardiography and standard care. The hypothesis is that a mobile team will lead to shorter hospitalization.
Study of the effect of oxygen on the frequency of central apnea, sleep and body temperature in patients with a cardiac disease
Background. The ROSCAP Study was a randomized controlled trial in heart disease patients to test the effect of a smoking reduction intervention on cigarettes per day (cpd) and biochemical and clinical indicators of tobacco exposure. .
