Filter by:The cardiac output (CO) is an important parameter in the diagnosis and therapy of cardiac diseases. The current standard methods for the determination of the CO, however, are either invasive (e.g. right heart catheterization) or technically expendable and expensive (magnetic resonance tomography, MRT). The traditional non-invasive methods of determining the CO by rebreathing of carbon dioxide are easily carried out but suffer from methodical inaccuracies. Therefore the aim of the study at hand was to evaluate a new method for determining the CO by means of the inert gas rebreathing method.
The purpose of the study is to help determine if either crystalloid solution or colloid solution is more advantageous as a resuscitative fluid in post-operative pediatric cardiac patients.
Myocardial scintigraphy with 123I-MIBG allows for visual and semi-quantitative assessment of sympathetic cardiac innervation using the hear to mediastinum ratio (HMR). Impaired cardiac MIBG clearance may occur in patients with congestive heart failure (CHF). The purpose of present study was to develop and validate a quantitative index for the assessment of cardiac MIBG uptake kinetics using SPECT/CT for diagnosis of CHF
This is a multicenter, randomized, double-blind trial, comparing clinical outcomes after the administration of high-dose dexamethasone versus placebo in patients undergoing heart surgery with the use of cardiopulmonary bypass. The primary endpoint is the occurrence of major complications (including all-cause mortality, myocardial infarction, stroke, renal failure, and prolonged mechanical ventilation) in the first 30 days after surgery.
The purpose of the project was to test the widely endorsed assumption that pedometers produce or encourage more physical activity participation in the form of walking. The investigators hypothesized that pedometers would not increase the amount of walking cardiac patients participated in after their cardiac rehabilitation program compared to patients without pedometers.
The goal of this study is to improve the overall physical health and quality of life of patients attached to mechanical heart devices while awaiting heart transplantation. Qigong, an ancient Chinese exercise that involves active participation of the individual in the form of meditation, breathing exercises and simple physical movements, is used in combination with a structured exercise program. We are testing the hypotheses that Qigong, in combination with a structured exercise program that combines aerobic and resistance training will improve the cardiovascular health and improve the quality of life of patients on mechanical heart devices. To test these hypotheses, we are measuring cardiovascular function and quality of life parameters in patients attached to mechanical heart devices who have participated in the exercise program and have practiced Qigong, and comparing these measures to patients who participated in the exercise program, but did not practice Qigong. Information gained from this research will serve as a basis from which the application of exercise training and Qigong can be applied to the treatment of other chronic diseases in which the physical conditioning and/or quality of life of individuals is compromised.
The aim of this study is to assess cardiac rate and respiratory responses and rhythm after workplace exposure to combustion particulates. A repeated measurement study is being performed on acute boilermakers (apprentices and journeymen). A stratified analysis is then done on those with and without chronic bronchitis, after adjustment for relevant covariates.
