Filter by:This randomized double-blinded controlled trial uses a factorial design to investigate whether application of beta-blockers (inderal 80 mg) or aspirin (100 mg) or a combination thereof has an effect on the activation of the hemostatic system, the platelets and the endothelium in response to acute mental stress. Specifically we test the hypothesis that inderal attenuates the activation of the hemostatic system as compared to placebo. The second hypothesis is that aspirin attenuates the activation of platelets as compared to placebo. Subjects will be randomly allocated to either of the four following study arms: placebo - inderal - aspirin - inderal plus aspirin. Subjects will receive the study medication for five days prior to the mental stress. The acute mental stress consists of a public speaking session of 10 min duration immediately followed by a mental arithmetic test of 5 min duration. Blood will be collected prior to the stress, immediately thereafter, at 45 min at at 1 hour and 45 min.
The purpose of this study is to investigate the changes of cardiorespiratory fitness and left ventricular function in type 2 diabetes after uncomplicated coronary artery bypass graft (CABG) surgery. We hypothesize that exercise capacity, left ventricular diastolic function, and biochemical data improves after 12-wk exercise training in patients with type 2 diabetes underwent CABG.
The primary objective of the study is to evaluate the efficacy of atorvastatin 80 mg daily as compared to atorvastatin 10 mg daily in reducing C-reactive protein levels over a 26-week treatment period in subjects with documented coronary artery disease.
The objective of ESPRIT was to compare the efficacy and safety of mild anticoagulation or a combination treatment of aspirin and dipyridamole with the efficacy and safety of treatment with aspirin alone after cerebral ischemia of arterial origin.
There is a remarkable lack of randomized trials concerning the potential benefit of using arterial conduits for coronary bypass surgery. This is the purpose of the present trial. Exclusive use of arterial conduits might result in improved conduit viability, reduced risk of recurrent angina, myocardial infarction and other cardiac events, reduced need for antianginal medication, improved functional status and possibly improved long term survival. The patients will be followed for ten years after surgery.
Cardiac surgery using heart and lung machine produces an inflammatory reaction in the body. This leads in few percent of cases to heart, lung, and kidney disturbances that potentially causes death. White blood cells in contact with the heart and lung machine and external surfaces release mediators partly responsible for this. Blood collected by the suction and the blood remaining in the heart and lung machine after its use, can be cleaned by a cell saver before reinfusion, and this might reduce the inflammatory response.
1) Establish normal value for coronary calcium scoring in Taiwan. 2) Find out the relationship of coronary calcium deposition and coronary artery stenosis. Propose a clinical management guideline based on coronary calcium score. 3) Evaluate sensitivity/specificity of coronary CT angiography and the influence of coronary calcium score on coronary CT angiography. 4) Evaluate the clinical application of myocardial enhancement measurement.
The study will examine the effects of estrogen and progesterone on the development of atherosclerosis in menopausal women when hormone treatment is initiated within 3 years of the menopausal transition.
Clinical studies have established that implantation of bone marrow mononuclear cells (BM-MNCs) or peripheral blood mononuclear cells (PB-MNCs) into ischaemic limbs increases collateral vessel formation. We, the investigators at Nagoya University, further investigated the efficacy and safety of autologous implantation of BM-MNCs or PB-MNCs in patients with severe ischaemic limbs who have no other alternative therapeutic options. We also examined a potential limiting factor which reduced the efficacy of therapeutic angiogenesis using cell transplantation (TACT).
The purpose of this study is to determine whether the radial artery (artery in the arm) or saphenous vein (vein in the leg), when used as bypass grafts for coronary artery bypass surgery, have a greater patency rate (degree of opening)at 5 years after surgery.
