The Effect of Fish Oil Supplementation on Endothelial Function, Heart Rate Variability and Intimal...
Coronary Artery DiseaseThe purpose of this study is to investigate whether there is a difference in endothelial function, heart rate variability and carotid intimal media thickness in patients with coronary artery disease who are receiving fish oil therapy. One hundred patients with established coronary artery disease by coronary angiography will undergo randomization for enrollment in the study. Baseline evaluation will include assessment of brachial artery endothelial function, heart rate variability and carotid intimal media thickness. Evaluation of the endothelial function of the brachial artery will be elucidated by inflation of a blood pressure cuff around the arm for five minutes and measuring blood vessel dynamics after release of the cuff. Heart rate variability will be evaluated by 24 hour holter monitoring and analysis by standard protocol. Carotid intimal media thickness will be evaluated by ultrasound measurements guided by predetermined protocol. Patients will then be randomized to a highly purified fish oil, Omacor, 1 gram twice a day or placebo. Brachial artery ultrasound and holter monitoring will be repeated at 2 months. Carotid ultrasound will be repeated at the end of the study at 12 months.
Efficacy of FX06 in the Prevention of Myocardial Reperfusion Injury

Influence of CPB Temperature on CABG Morbidity
Cardiovascular DiseasesCoronary Disease3 moreTo compare three accepted modes of myocardial preservation, warm, tepid, and cold blood cardioplegia, coinciding with normothermic (37 degrees centigrade), tepid (32 degrees centigrade) and hypothermic (8 to 10 degrees centigrade) cardiopulmonary bypass (CPB) to define differences in neurologic function in coronary artery bypass graft (CABG) patients.
The Randomized OPTIMAL-ACT Trial
Coronary Artery DiseaseIschemic Heart Disease2 moreThe purpose of this study is to find the ideal range of the activated clotting time (ACT) during percutaneous coronary intervention (PCI) that is associated with lowering the rate of undesirable medical outcomes
Singapore Cardiac Longitudinal Outcomes Database
Coronary Artery DiseaseCongestive Heart Failure1 moreThe research project aims to perform data extraction, integration and analysis across multiple clinical, administrative, financial and pharmacy databases in the participating institutions. The key data components will include clinical cardiovascular specific data, procedural data, financial and administrative data (e.g. cost of medications and supplies, length of stay, diagnosis codes etc.), short-to-long term clinical outcomes (including hospital re-admissions, cardiovascular events, death), and quality-of-care indices (e.g. compliance to guideline-recommended therapy and medications). The research project will involve all patients proven and/or suspected with coronary artery disease (CAD), congestive heart failure (CHF) and atrial fibrillation (AF) admitted to National Heart Centre Singapore (NHCS) and NUH.
Time for a Paradigm Shift: STEMI/NSTEMI to OMI/NOMI ?
Myocardial InfarctionMyocardial IschemiaThe current ST-segment elevation (STEMI)/non-STEMI treatment paradigm misses nearly one fourth of acute coronary occlusions (ACO) that needs immediately reperfusion. Many of these cases can be recognized by subtle changes on ECG, but the current STEMI criteria do not include them. The investigators of this research believe a new occlusive/non-occlusive myocardial infarction (OMI/NOMI) approach will be superior to the established STEMI/non-STEMI paradigm in early detection of ACO, limiting infarct size, reducing re-hospitalizations and most important of all, reducing mortality.
"TransRadial Ultra Support Technique" (TRUST)
Coronary ArteriosclerosesCoronary Artery DiseaseAdequate support is required for challenging percutaneous coronary interventions (PCI). The "TransRadial Ultra Support Technique" (TRUST technique) is a new support technique that provides active support by deep pass of the coronary wire into the heart cavities (left ventricle-LV, right ventricle-RV) or aorta.
Timing of Complete Revascularization for Multivessel Coronary Artery Disease in STEMI
Myocardial InfarctionThe study will compare clinical outcomes between complete revascularization during hospitalization for ST elevation myocardial infarction (STEMI) and intervention after 30 days and intervention based on outpatient non-invasive ischemia testing in patients with multivessel coronary artery disease (MVD) presenting with first ever ST elevation myocardial infarction.
Fractional Flow Reserve Versus Angiography Randomization for Graft Optimization Trial
Coronary Artery DiseaseCoronary Disease3 moreThe FARGO trial is a prospective, randomized (1:1), multicenter study. The aim of the study is to assess the importance of fractional flow reserve (FFR) assessment prior to coronary artery bypass grafting (CABG) with respect to planning and guiding the revascularization strategy. The study compares an FFR-guided strategy to an angiography-guided strategy in patients planned for surgical revascularization.
