Filter by:This study will conduct an initial clinical evaluation of this support program to examine its impact on reducing caregiver stress, increasing confidence in daily feeding, and improving weight-for-age growth percentiles in infants with Congenital Heart Disease (CHD).
A novel magnetic resonance (MR) compatible accelerometer for respiratory motion sensing (MARMOT) has been developed as a surrogate of the vendors' pneumatic belts. The aim is to model and correct respiratory motion for free-breathing thoracic-abdominal MR imaging and to simplify patient installation.
This is a single center, randomized controlled trial which will include women with ischemic heart disease to receive either a self-directed stress reduction program delivered through a smart-phone application or activity tracking only for the first month ("early SR intervention" and "delayed SR intervention", respectively). Patients will be monitored for 1 month for application use and step counts via telephone or email interview and/or collection of screen-captured data. Baseline questionnaires will be repeated at the end of one month to assess for all primary and secondary measures, at which time the control group (activity tracking only) will be introduced to the intervention program. The early SR intervention group will not receive a new intervention but will be encouraged to continue using the app. Data will be collected for an additional 2 months with all participants in both groups. After the three-month study period, the study will close with the collection of final questionnaire data.
This study will explore new ways of using magnetic resonance imaging (MRI) to evaluate pediatric patients with cardiovascular disease,congenital heart disease in patients of all ages, fetuses undergoing clinically indicated MR imaging.
Study on the registration of coronary heart disease patients undergoing PCI in Chinese's population. Get the incidence of adverse events in these patients after PCI, a clear type of adverse reaction, forms, influencing factors, to establish risk management processes, clinical safety and reasonable treatment, and provide the basis for further research and reference.
This is a pilot study that seeks to evaluate the feasibility and safety of using a TEG algorithm in addition to traditional laboratory tests to guide transfusion and coagulation management of ECMO patients.
The primary objective of this investigation was to assess the impact of new mobile health devices on health outcomes among patients with rheumatic and structural heart disease in a resource limited area. To achieve this aim the investigators utilized smartphone-connected devices such as the smartphone-ECG, activity monitors, connected blood pressure devices and pocket-sized and handheld ultrasound. The main question asked in this investigation is if mobile health assessments accelerates medical-decision-making and if it shortens the time to definitive therapy.
Exercise treadmill test (ETT) is frequently done, inexpensive, relatively safe investigation for diagnosis of ischemic heart disease and prediction of exercise capacity. Ischemic heart disease is increasing by leaps and bounds all over the world even in the developing countries like Bangladesh. The incidence rate of coronary artery disease (CAD) is not limited to male gender as previously seen. As a cause of industrialization and increased life expectancy, incidence of ischemic heart disease in females is escalating now in Bangladesh also. Though ETT is a well accepted investigation to diagnose CAD, it has a high false positive and false negative result if ST segment response alone is calculated for interpretation of the test. Duke Treadmill Test and Simple Treadmill Test are valid and well known scores which can predict coronary artery disease burden more efficiently than ST segment response alone. Computer generated Cleveland clinic score is another valid treadmill score which has a complex algorithm but effective way to predict 3 year and 5 year survivability. These three scores are well tested on western population but to our best knowledge there is little or no information regarding their predictability of CAD in Bangladesh. It's well known that ETT has a high false positive result in female population, so applying the scores may render ETT more efficient and abrogate unwanted risk of undergoing coronary angiography to diagnose CAD in females. In this study the investigator will try to find out the accuracy of commonly applied treadmill scores and ST segment response to diagnose CAD as well as accuracy of computer generated Cleveland Clinic Score will be tested. Total 110 people including male and female will be included according to inclusion and exclusion criteria and informed written consent will be taken. The patients who have undergone ETT and coronary angiogram with in six months for confirmation and identification of coronary artery disease in accordance with the recommendation of ACC guideline for CAG will be selected . All available data will be analyzed using SPSS. The accuracy of different scores will be calculated and compared with each other. According to currently available data from studies in western population the treadmill scores will have good predictability and will be efficient to abolish high false positive result in female population in Bangladesh.
Remote ischemic preconditioning (RIPC) of the myocardium by limb ischemia/reperfusion may mitigate cardiac damage, but its interaction with the anesthetic regimen is unknown.
In the last few years, anaesthetics gas such as isoflurane, desflurane and sevoflurane used in heart surgery have shown some benefits to reduce the risk of heart muscle damage than total intravenous anesthetics. A study by the investigators suggested that isoflurane needs a longer duration to achieve equilibrium between coronary sinus and radial artery, indicating that isoflurane in coronary sinus does not accurately reflect its level in the heart muscle. Different agents have unique characteristics with different equilibration rate. However, the levels of sevoflurane and desflurane in coronary sinus and radial artery have not been measured. In addition, lactate is believed to be a very useful indicator to predict the outcome of recovery phase after any surgery. This study aims to measure the level of sevoflurane or desflurane in blood circulation. It will also assess whether sevoflurane or desflurane concentration in the blood is correlated to the its oxygenator exhaust level and affected by temperature, haematocrit level and gas flow rate during heart-lung machine. It also aims to examine the association of lactate and the outcomes of cardiac patient in intensive care unit after cardiac surgery.
