Filter by:It is well know that statins have been used to low cholesterol to prevent and treat coronary artery disease for many years. It was also reported that statins could protect endothelial function and cardiac function during coronary artery bypass graft. However, some results were controversial. Also, there is no clinical data available on statin cardiac protection during surgery in China where rheumatic heart disease is prevalent. Thus, the investigators are trying to see whether statins can protect heart injury during cardiac surgery in Chinese. Part of patients will receive statin treatment and part of will not before surgery in the study. Both patients' heart function will be measured and compared after surgery to determine whether statins can protect heart injury during heart surgery.
This study is an epidemiological observational cross-sectional study designed to estimate the prevalence of echocardiographically confirmed RHD in school children from 5-14 years of age in Fiji. The study will be conducted in the Central Division of Fiji within a selection of up to16 primary schools located in the Korovou/Tailevu and Rewa/Nausori sub-divisions. School children will be enrolled after informed consent has been obtained. A standard cardiac examination (auscultation) will be performed as part of the routine annual health check by both school nurses, who have attended a training workshop, and by a paediatrician. All children with or without murmur will have a screening echocardiogram performed at a subsequent visit. Children found to have possible, probable or definite RHD or other cardiac pathology on the screening echocardiogram, will have a full echocardiogram performed by the echocardiography technician at the time of the second study visit. They will all also be referred to a paediatric cardiologist for further investigation and management and monitoring . Cases of RHD will be referred to and followed up by the National Fiji RHD register based at CWMH in Suva.
The hemodynamic parameters of 31 pregnant women with rheumatic valve disease, undergoing restorative dentistry under local anesthesia with 2% solution of lidocaine, divided in two groups, with (Group LE) and without 1:100,000 epinephrine solution (Group LNE), were studied by 24-hour ambulatory electrocardiographic monitoring, intermittent blood pressure monitoring and continuous cardiotocography, during three standard time periods. A significant decrease in the values of maternal heart rate was seen during the procedure, in comparison with the other two time periods in the two groups, as well as, the occurrence of cardiac arrhythmia in 9 (29.1%) patients, being 7 (41.8%) of them in the group receiving epinephrine anesthesia. We conclude the use of 2% lidocaine in association with epinephrine proved safe during dental procedure in pregnant women with rheumatic valve disease.
A bacterium called Group A Steptoccoccus or "strep" is commonly found in the nose and throat of healthy adults and children and can cause a variety of illnesses. If this bacterium infects another part of the body one or more times, children may get Rheumatic heart disease (RHD). The purpose of this community based study is to see how many children between 5-15 years of age have RHD in Leon, Nicaragua. The study will also help to determine if the usual methods of detecting this disease are working. Researchers hope that this study will help to develop vaccines that may prevent "strep" infections to Nicaragua and other parts of the world. About 3,600 children will take part in the study. The children will participate for a minimum of 1 day and have a 6 month follow-up visit if they are identified as possible or probable RHD cases. Study procedures will include clinical exams and echocardiograms to determine the presence of RHD.
The current study was designed to determine whether the HLA-DRB1, DQA1, DQB1 alleles are associated with the risk and the pattern of valve damage of RHD.
