Filter by:Endothelial dysfunction is an early marker of atherosclerosis and is found in patients (pts) with coronary (CAD) and peripheral artery disease (PAD). Statin-therapy has been shown to improve endothelial function in pts with CAD or PAD by reducing LDL-cholesterol and inflammatory markers. B-group vitamin-supplements have variable been reported to have positive or neutral effects on endothelial function. Therefore, we want to compare the effect of rosuvastatin and B-group vitamin supplementation on endothelial function of the forearm resistance vessels in pts with cardiovascular disease.
Non interventional study aimed to establish the prevalence of lower extremity peripheral arterial disease (PAD), defined as an ankle-brachial index (ABI) not above 0.90 in subjects with a moderate risk of cardiovascular disease, with no overt cardiovascular diseases nor diabetes mellitus.
The purpose of this study to examine whether vitamin D can reduce the activation of the immune system during dialysis. When activated, the immune cells release certain substances, called cytokines, which can be measured from small blood samples. We want to study to what degree the immune system is activated during a regular dialysis treatment and whether the time point of vitamin D administration, either right before the start or right at the end of a dialysis treatment, has an impact on the activation of the immune system.
Eleven National Sports Teams are located in the Quebec Metropolitan Area. In these groups, many athletes are aiming for Olympic medals in Beijing 2008 and Vancouver 2010 Olympic Games. A consultation of the coaches of these National Teams revealed that although a large proportion of these athletes present various cardio-respiratory symptoms, they do not have a rapid access to a systematic medical evaluation and follow-up. Furthermore, little is done in regard to prevention and optimization of treatment of pulmonary and cardiac conditions in the elite athlete's population of the Quebec area. Cardiorespiratory problems are therefore commonly found in high-level athletes. However, these pathologies are not well characterized in athletes and the associated symptoms often not well perceived. These problems can be serious and it is important to detect them before they appear1 while setting up a systematic medical follow-up. Health professionals should monitor health of the young athletes and help to reduce the risks associated with high level exercise. The following project is an evaluation and follow-up program of high-level athletes, aiming at gathering key-information on long-term effects of high-level training on cardio-respiratory and metabolic parameters. Our aims will be 1. to establish a long-term program of systematic evaluation and follow-up of cardiorespiratory health and performance of high elite athletes. 2. to evaluate the prevalence of respiratory, circulatory and metabolic problems among high-level athletes 3. to evaluate the effects of treatments on cardiorespiratory conditions and exercise performance in athletes who need asthma medication.
The investigators' project has for principal objective to evaluate the impact of three specific ruminant milk fats with a Trans Fatty Acid content ranging from 2.9% to 12.2% obtained by modification of the cow's diet on cardiovascular risk factors in healthy subjects.
Cardiac rehabilitation programs (CRP) are a proven treatment for those with ischemic heart disease (IHD). These programs have been demonstrated to improve adherence to regular physical activity, a healthy diet and smoking cessation, as well as modify risk factors for IHD such as hypercholesterolemia, hypertension, obesity and type 2 diabetes. In addition, CRP are cost effective and can result in a 25% reduction in reoccurrence of mortality. Despite the known benefits of CRP, as little as 10% to 25% of eligible patients attend these programs. One of the main barriers to attendance is proximity to a CRP, as the majority of these programs are limited to hospitals in large urban areas. However, cardiovascular diseases do not discriminate by geography, resulting in a geographic inequity of care for patients living in rural, remote and smaller urban/sub-urban centres. Currently there are no CRP specifically designed for patients in rural and remote areas. The use of the Internet may present itself as a viable alternative. We have recently completed a pilot study of a virtual CRP (vCRP) that demonstrated significant improvements in exercise capacity and risk factors. This investigation will study the vCRP in a group of IHD patients who do not have access to hospital-based CRP. Hypotheses A. Participation in a 4 month Internet-based cardiac rehabilitation program will result in significant improvements in exercise capacity compared to usual care, in patients with diagnosed IHD. B. Participation in a 4 month Internet-based cardiac rehabilitation program will result in significant improvements in exercise capacity after one year compared to usual care, in patients with diagnosed IHD. Study Population Men and women over 18 years will be identified from consecutive in-patients of the British Columbia Provincial Heart Centre at St. Paul's Hospital in Vancouver who reside in either the Northern Interior or Coast Garibaldi health areas. Patients will be eligible if they have IHD, Internet access, no previous experience with cardiac rehabilitation and no physical limitations to exercise. A total of 74 patients (37 per group) will be recruited and randomized to either usual care, or a 4 month 'virtual' cardiac rehabilitation program delivered via the Internet. Usual Care Group Patients randomized to usual care will be provided with simple guidelines for safe exercising and healthy eating habits, and return to the care of their primary care physician. Patients will return at 4 and 16 months later for outcome assessment. There will be no contact between the study personnel and usual care patients for the duration of the study, nor will there be any attempt to control the level of patient care. Intervention The vCRP has been developed to mimic hospital-based CRP and includes online intake forms, one-on-one chat sessions with vCRP nurse, dietitian and exercise specialist, data collection (exercise heart rate, blood pressure, glucose- if diabetic), peer-support group chat sessions, ask-an-expert chat sessions, education, progress reports and online resources. Upon randomization to the intervention, patients will receive access to the website, a heart rate monitor and a blood pressure monitor and trained in their use. The heart rate monitors allow for exercise heart rate data to be stored and downloaded to their home computer and then uploaded to the vCRP webserver. The exercise data will be reviewed weekly. A letter to the patient's primary care physician will be sent to outline the vCRP intervention, the treatment algorithms to be used and indicate under what circumstances the vCRP nurse and/or patient may contact them with regards to their management. Patients will receive one-on-one counselling by the nurse, dietitian and exercise specialist via chat sessions at 3 to 4 week intervals. After the 4 month intervention, patients will be discharged into the care of their primary care physician. Outcomes Participants will be assessed at baseline, 4 and 16 months for risk factors and lifestyle behaviours. The primary outcomes will be the change in exercise capacity as between the two groups from baseline to 4 months, and from baseline to 16 months. Exercise capacity will be assessed as total time on a symptom-limited exercise stress test.
The aim of the present study was to determine the effects of a multidisciplinary approach and intensity-controlled interval training on cardiovascular risk factors in overweight adolescents
The purpose of this study is to investigate the burden of upper gastrointestinal symptoms in patients with cardiovascular disease taking low dose aspirin
The purpose of this placebo controlled trial is to determine whether a year long intervention with flavonoids (found in cocoa and soy) is more effective in reducing the risk of cardiovascular disease in postmenopausal women with type 2 diabetes, than standard therapy (statins). A range of markers of cardiovascular disease risk are being studied and volunteers are also providing urine and blood samples. 152 postmenopausal women, from the locality, will be recruited for this study.
The purpose of this study is to determine whether cyanoacrylate tissue adhesive is as effective as polyglactin 910 suture for surgical closure of cardiac device pockets.
