Mobile Health Strategies for Veterans
Coronary Heart DiseaseThe purpose of this study is to determine whether text messages/messaging (TM) or a mobile application (app), compared with an educational website-control provided to all Veterans, can improve adherence to antiplatelet therapy among patients following acute coronary syndrome or percutaneous coronary intervention (ACS/PCI).
Loop Isolation-based Uploading Pre-conditioning
Ischaemic Heart DiseasesMyocardial protection is of crucial importance for surgical coronary revascularization in patients with ischaemic heart diseases. The investigators proposed loop isolation-based uploading preconditioning to protect heart from ischemic-reperfusion damage (LiuPhD) as a novel cardioprotective strategy, and applied to patients who underwent on-pump coronary artery bypass grafting (CABG).
A Study to Identify the Incidence of Post Traumatic Stress Symptoms in Patients With Delirium Following...
Cardiac DiseaseDelirium2 more'Post perfusion syndrome' was a term historically associated to cardiac surgery in view of the transient neuro-cognitive deficits attributed to cardio pulmonary bypass pump. During their recovery period, a significant number of patients experience delirium, a clinical syndrome of acute onset and fluctuant course.Though these deficits are often known to be transient without any permanent physical or neurological impairment, the experience can still psycho-socially affect these patients for a longer length of time even after discharge. The presence of delirium puts excessive, undesired strain on the patient, their families, health care providers and hospital resources. PTSS is an anxiety disorder caused by very stressful, frightening or distressing events. It is known to either develop immediately after the disturbing event or weeks and months later. The actual symptoms can be varied but are categorized in three sections: i.e.: re-experiencing, avoidance and emotional numbing and hyperarousal (feeling 'on edge'). A problem that has such an impact on any patient is worth investigating and understood better. Being in such a unique professional position, as a Clinical nurse practitioner, the investigator is ideally placed to conduct this study. In this study, the researcher will be focusing on the pre-operative risk factors in developing delirium, actual incidence of delirium and follow the patients post operatively to evaluate the after effects of delirium in the form of PTSS.
Heart Rate Variability (HRV) Testing Compared With Exercise Stress Test in Hospitalized Patients...
Angina PectorisIschemic Heart DiseaseThere are many patients hospitalized for chest pain, which don't have high risk features that require invasive coronary angiography, but are considered intermediate risk and for which ischemic heart disease can not be excluded. The current management for these patients is to perform a non invasive test in order to classify their risk. Exercise ergometry is a commonly used non invasive test to detect ischemia. that test is non-invasive, and does not involve radiation or intra-venous contrast. The test is limited for many patients, because of un-ability to exercise, or because of non-interpetable Electro Cardio-Graphy (ECG). Heart rate variability is well known to be a marker of ischemic heart disease. Heart rate variability testing is a non-invasive ECG monitoring technique. The study design is to identify hospitalized patients who are candidates for non-invasive stress testing, and to monitor their heart rate variability for one hour prior to the stress test.
Study of RV Remodeling in Congenital Heart Disease
Congenital Heart DiseaseThe primary aims of this study are to 1. Develop an automated method of quantitation of RV remodeling in terms of regional RV surface curvature and area strain and assess the feasibility, repeatability and accuracy in normal subjects and patients with repaired TOF, patients with PS The secondary study aims of this study are to 1. Compare the differences of RV remodeling in repaired TOF patients, PS patients with sex and age-matched controls 2, Assess the relationship of our proposed parameters to global RV function and exercise capacity in repaired TOF patients and PS patient
The Role of the Pulmonary Vasculature in the Fontan Circulation
Congenital Heart DiseaseFontan Operation2 moreThis study aims to explore the structural and functional characteristics of the pulmonary vasculature in adult Fontan patients. Objectives: Determine the effect of pulmonary vasodilatation on indexed cardiac output during simulated exercise. Characterization of structural properties of small pulmonary arteries.
Meta-analyses of Total and Individual Fructose-containing Sugars and Incident Cardiometabolic Disease...
OverweightObesity10 moreSince uncontrolled observational studies first linked fructose to the epidemic of obesity almost a decade ago, it has become a focus of intense concern regarding its role in the obesity epidemic and increasing burden of cardiometabolic disease. Despite the uncertainties in the evidence, international health organizations have cautioned against moderate to high intakes fructose-containing sugars, especially those from sugar sweetened beverages (SSBs). To improve the evidence on which nutrition recommendations are based, the investigators propose to study of the role of fructose-containing sugars in the development of overweight/obesity, diabetes, hypertension, gout, and cardiovascular disease, by undertaking a series of systematic syntheses of the available prospective cohort studies. Prospective cohort studies have the advantage of relating "real world" intakes of sugars to clinically meaningful disease endpoints over long durations of follow-up. The findings generated by this proposed knowledge synthesis will help improve the health of consumers through informing recommendations for the general public, as well as those at risk of diabetes and cardiovascular disease.
Safety Study of Dengzhanxixin (a Chinese Medicine Injection) Used in Hospitals in China
Ischemic StrokeCoronary Heart DiseaseThis study was advocated by Institute of Basic Research in Clinical Medicine, China Academy of Chinese Medical Sciences in October 2011. It was funded by China major scientific and technological specialized project for 'significant new formulation of new drugs'. Dengzhanxixin is kind of Chinese Medicine injection used for treating Ischemic Stroke and coronary heart disease in many Chinese hospitals. The purpose of this study is to determine adverse drug events or adverse drug reaction in large sample size 30,000 patients.
