Filter by:Background: Coronary heart disease (CHD), the most prevalent type of cardiovascular disease among adults, has been identified as one of the chronic diseases which are epidemic in the world. Teaching and encouraging the working population to adopt a healthier lifestyle could favor in preventing and/or decreasing the incidence of CHD among this population. The use of mobile application (app) is the next logical wave of healthcare support tools to prevent and manage chronic diseases like CHD. Aims: The aims of the study are to develop a mHealth programme, entitled "Care4Heart" for the working population in Singapore, and thereafter examine its feasibility and effectiveness in increasing the awareness and knowledge of coronary heart disease (CHD) as well as improving their heart-related lifestyle. Methods: A two-phase study design will be adopted. Phase 1 is a pilot, two-arm randomized controlled trial (RCT) study and phase 2 is a single group pretest and repeated posttest longitudinal study. The study will be conducted in National University of Singapore. A convenience sampling will be used, and a total of 240 healthy working adults will be recruited via posters advertising in campus canteens, which comprising 80 participants in Phase 1 and 160 participants in Phase 2 study. The first recruited 80 participants will be randomly allocated to an intervention group and a control group, and only those in the intervention group will receive 4-week "Care4Heart" programme. For the participants recruited in phase 2 (n = 160), the newly developed mobile app will be installed onto their' smartphones, and a well-trained research assistant will brief the participants about the utilization of the app. The main outcomes will be measured using the survey questionnaires: Awareness of CHD, Heart Disease Fact Questionnaire-2, Behavioral Risk Factor Surveillance System and Perceived Stress Scale. Data will be collected at baseline, and at the 4th week for phase 1 study while a third data collection at the 6th month thereafter will be conducted for phase 2 participants. Data will be analyzed using IBM SPSS 22.0. Applications: If this project is proved to be feasible and effective, "Care4Heart" app, a novel CHD prevention programme will be popularized nationwide to promote knowledge and elicit positive heart-related behavioral changes for the working population in Singapore
- 1. Coronary artery bypass grafting (CABG) could be performed with or without extracorporeal circulation (ECC). - 2. OSA (Obstructive Sleep Apnea) could be influenced by in intravenous perfusion. - 3. ECC could influence the amount of intravenous perfusion administered to the patient. The aim of this study was to examine the influence of ECC on the development of OSA.
To examine whether Konjac-mannan fiber improves metabolic control measured by glycemia, lipidemia, and blood pressure in individuals with type-2 diabetes.
Prospective interventional study, open, non-comparative and non-randomized. The research concerns physiological parameters of the coronary and ocular blood circulation. At the coronary level, the curves of pressure and Doppler flow will be extracted from ComboMap® (Philips). The coronary microvascular resistances, basal and hyperemic, will be determined by the average ratio of the distal pressure and flow. At the ocular level, a fundus oculi and an OCTA (angiography by tomography in optical coherence) examination will be performed. The measures of the FFR and the coronary microvascular resistance will be determined by a guidewire allowing measures of pressure and by a guidewire allowing measures of Doppler flow (ComboWire®, Volcano), in 123 patients with intermediate stenosis of the left anterior descending artery (LDA). Topological parameters characterizing the retinal area and choriocapillaries will be determined by statistical approaches and mathematical morphology. To establish a predictor of the coronary microvascular resistance from the eye vascular parameters, we shall use a non-linear regression by supervised machine learning. The main cardiovascular risk factors (hypertension, diabetes, dyslipidemia, age, sex) will be part of predetermined input features for the machine learning.
This study evaluates cardiac biomarkers and their association to coronary artery disease in marathon runners.
This prospective registry is intended to evaluate the safety and efficacy of the Optimax® stent.
A large number of patients with symptomatic ischaemic heart disease undergo coronary artery bypass grafting (CABG) to alleviate their symptoms and improve prognosis. Given the progressive nature of coronary disease, bypass grafts can narrow or block over time, leading to chest pain and the need for further invasive coronary angiography. Invasive coronary procedures in patients with bypass grafts can be more complicated due to the variation in bypass graft ostia. This can lead to longer procedure times, with higher doses of contrast and radiation and more discomfort for the patient. The aim of this study is to see if the use of computed tomography cardiac angiography (CTCA) in patients with previous bypass grafts prior to invasive coronary angiography will help make their procedure safer and quicker.
The present study will investigate the effect of acute exercise on fasting and postprandial risk markers for coronary heart disease (CHD) in healthy male cigarette smokers and non-smokers. Participants will complete two, 2-day trials in a random crossover design separated by an interval of at least 1 week. On day 1, participants will rest (control) or complete 60 minute of treadmill exercise at 60% of maximum oxygen uptake (exercise). On day 2, participants will rest and consume two high fat meals (breakfast and lunch) over an 8-h period during which 13 venous blood samples and nine blood pressure measurements will be taken at pre-determined intervals. It is hypothesised that men who smoke cigarettes will exhibit impaired fasting and postprandial metabolic risk markers compared to non-smokers, but a single bout of exercise will be equally, if not more, efficacious for improving the CHD risk factor profile in smokers than non-smokers.
The purposes of this study are 1) to explore the association between facial characteristics and the increased risk of coronary artery diseases; 2) to evaluate the diagnostic efficacy of appearance factors for coronary artery diseases.
Study objective - to assess the efficacy, tolerability and adherence of bisoprolol/perindopril FDC in patients with HT and stable CAD in everyday practice. Type of the program: multicenter, observational, uncontrolled, open program. The program will involve 480 general practitioners (GPs) and cardiologists from the primary care facilities.Each doctor includes four patients. It is planned to include not less than 1920 patients in total.
