Filter by:The aim of this study is to find strategy for treatment through comparing the cardiopulmonary exercise test parameters before and after cardiac rehabilitation in patients with chronic total occlusion of the coronary arteries.
To determine associations between dietary factors and risk of major chronic diseases and their risk factors
Ischemic Heart Disease (IHD) is a condition of recurring chest pain or discomfort that occurs when a part of the heart is not receiving sufficient blood flow. It is a major public health concern internationally and in Singapore, the leading cause of death from cardiovascular disease. Cardiovascular magnetic resonance (CMR) has the ability to assess heart structures, scarring or lack of blood supply to the heart muscle with great accuracy and without any radiation involved. A CMR-compatible cycle ergometer can offer a safe and low cost stress equipment to assess heart function and motion abnormalities, and restrictions of the blood supply to the heart tissues due to partial or complete blockages of the blood vessels. This study aims 1. to develop an exercise-CMR stress protocol by testing its feasibility and robustness in assessing changes in cardiac volumes and function due to physical exertion in healthy individuals and 2. to assess the accuracy of the multiparametric stress-CMR as a diagnostic tool for ischemic-causing coronary artery disease (CAD) with coronary fractional flow reserve (FFR) as a reference. 3. to measure the overall economic impact of ischaemic heart disease by estimating the direct and indirect medical costs for each participant. The current sample costs will be extrapolated to estimate the annual costs of treating and managing ischaemic heart disease in the local population. 4. to evaluate the effects of coronary microvascular dysfunction on coronary flow and regulation, physiological response and cardiac sympathetic signaling in patients with chest pain.
The aim of the Danish Organisation for randomised trials with clinical outcome (SORT OUT) is to compare the safety and efficacy of the ComboTM stent and Orsiro™ stent in the treatment of unselected patients with ischemic heart disease, using registry detection of clinically driven events.
This is an analysis conducted in the Nurses Health Study and the Health Professional Follow-Up Study, both prospective cohort studies, where the investigators systematically investigated the association between carbohydrate quality using a variety of metrics in relation to coronary heart disease. This was a secondary data analysis of previously collected data in both cohorts.
The purpose of this study is to explore the facial characteristics associated with the increased risk of coronary artery diseases. The secondary purpose is to evaluate the diagnostic efficacy of appearance factors for coronary artery diseases.
The impact of frailty on immediate and long term outcomes of invasive treatment of coronary artery disease is not fully characterized. The assessment of frailty may help physicians in the selection of best treatment option and in the timing and modality of the follow-up. The FRAilty syndrome in daily Practice of Interventional CArdiology ward (FRAPICA) study is designed with the aim to validate the use of the Fried frailty scale and instrumental activities of daily living scale (IADL) as prognostic tools in patients admitted to hospital for symptomatic coronary artery disease, either stable, unstable, or acute coronary syndrome (ACS). The FRAPICA study is a single center prospective study enrolling patients aged ≥65 years. The aims are (1) to describe Fried frailty scale and IADL scale distribution before hospital discharge and (2) to investigate the prognostic role of Fried frailty and IADL scores. The outcomes are: (1) results of invasive treatment, (2) its complications (periinterventional MI, contrast-induced nephropathy, blood loss), (3) three-year all-cause mortality, cardiovascular mortality, stroke, myocardial infarction, reintervention, heart failure, hospital readmission for any cause, and a composite of the above mentioned. Ancillary analyses will be focused on different clinical presentations, different tools to assess frailty and risk stratification. The FRAPICA program will fill critical gaps in the understanding of the relation between frailty, cardiovascular disease, interventional procedures and outcome. It will enable more personalized risk assessment and identification of new targets for interventions.
Regular exercise training has shown to improve exercise capacity in patients with cardiovascular disease. The feasibility and transferability of exercise training in a community based cardiovascular rehabilitation setting is currently less well investigated. The objective of this study is to translate regular exercise training into a community based setting. A 6 months training intervention program with lifestyle counseling is performed, with both supervised training in rehabilitation centres as well as home based training. The aim of the project is to implement this program for a wider patient population and to improve exercise capacity, diastolic function as well as cardiometabolic parameters.
This trial evaluates the effects of Empagliflozin versus Sitagliptin, in addition to standard of care, on global myocardial perfusion reserve using dynamic single-photon emission computed tomography (SPECT) images.
This study evaluates a smartphone-based cardiac rehabilitation program in adults with coronary artery disease. Half of patients will participate in a smartphone-based cardiac rehabilitation program while the other half will receive standard-of-care.
