Filter by:Older and more frail adults are more often being referred for cardiac surgery. These patients are often in suboptimal health, and may be physically frail, malnourished, and have other conditions, such as diabetes, that complicate their recovery. Research suggests that a rehabilitation program prior to surgery may help improve participants' health and improve their fitness for surgery. Currently, a pre-operative rehabilitation workshop is offered at the University of Ottawa Heart Institute, but this interventional, randomized study will investigate whether a more comprehensive pre-operative regime, including structured weekly exercise program, is more effective at improving health prior to surgery. Patients will be randomized to either the control group (pre-operative rehabilitation workshop ONLY) or the treatment group (pre-operative rehabilitation workshop plus exercise regime). This regime will attempt to improve patients' overall health, including their physical fitness and nutritional status. The effectiveness of this regime will be evaluated by comparing patients' physical function, questionnaires (diet, quality of life, stress) and serum biomarkers from baseline to pre-surgery to post-surgery. The Investigators hypothesize that patients that complete the pre-operative rehabilitation program will improve their health prior to surgery, and that this may result in shorter length of hospitalization and fewer complications after surgery. The study will take place over two years, with each patient's participation lasting about 3 months.
The aim of this study is to explore the effect of newly added SGLT2I medication or placebo, to standard medication regimen in diabetic patients with documented stable coronary disease. Therefore, in the present study the investigators plan to focus on possible anti-inflammatory and athero-thrombotic protective effects of Dapagliflozin compared to placebo, in secondary prevention population of stable coronary patients with diabetes. Additionally, the investigators will explore NT proBNP dynamics, which related to ventricular filling pressures in this specific population.
Cardiac shock wave therapy (CSWT) is a noninvasive new therapeutic option in the treatment of chronic refractory angina pectoris. Many domestic and international researches have revealed that CSWT contributes to revascularization by stimulating angiogenesis. We were aimed to evaluate the safety and efficiency of CSWT in the treatment of refractory angina.
This study is designed to evaluate the efficacy, safety and tolerability of autologous bone marrow derived mesenchymal stem cells compared to placebo (sham operation) when administered via percutaneous coronary infusion to patients with ischemic heart disease, who are screened by D-SPECT and have pretreated with 3-month cardiac shock wave therapy.
Fruit and vegetables are a cornerstone of healthy dietary patterns and dietary guidelines worldwide. The supporting evidence, however, is largely derived from observational studies of protective associations with cardiovascular disease (CVD) in health-conscious populations or from randomized trials of the effect of specific fruit or vegetable derived nutrients on CVD risk factors. A growing body of literature has influenced a shift away from a focus on single nutrients to a focus on whole foods and dietary patterns. To what extent fruit and vegetables should contribute to dietary patterns for cardiovascular health and whether specific types of fruit or vegetables should be recommended is unclear. Although previous systematic reviews and meta-analyses have elucidated the association between the intake of total and some specific fruit and vegetables with cardiovascular outcomes, a comprehensive synthesis comparing the certainty of the evidence for the different types of fruit and vegetables in relation to a range of cardiovascular outcomes has yet to be completed. We propose to conduct a systematic review and meta-analysis of the available prospective cohort studies using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to assess the association between different types of fruit and vegetables and different cardiovascular outcomes that include CVD, coronary heart disease [CHD], and stroke incidence and mortality.
Exercise is commonly recommended as a treatment for patients who present with peripheral artery disease (PAD). Although a great deal of research has supported the efficacy of exercise rehabilitation for PAD, it is infrequently implemented into clinical practices.To date, no comparison of cardiac rehabilitation efficacy and acute exercise responses has been made between patients with PAD and patients with coronary artery disease (CAD). Considering some of the parallels between the two conditions, as they are both atherosclerotic conditions, and the strong recommendations for exercise in both populations, it is worthwhile to compare the efficacy of cardiac rehabilitation responses. It is also unclear if the magnitude of response for PAD patients is dependent on biological sex and clinical presentation as this may influence the development of exercise prescriptions. This study will be a prospective two-arm cohort study with both groups (CAD and PAD) undergoing the same intervention (standard 6 month out-patient cardiac rehabilitation program offered at the Toronto Rehabilitation Institute Rumsey Centre). The primary variable of interest will be peak oxygen consumption (VO2peak) with a secondary variable of interest being functional capacity, as measured by the 6-minute walk test. Tertiary variables of interest will include walking impairment, as measured by the Walking Impairment Questionnaire, and quality of life, as measured by the Short Form-36 health survey (SF-36).The second objective of this study is to determine if the magnitude of responses to cardiac rehabilitation for patients with PAD are dependent on biological sex or type of PAD (asymptomatic, post-surgical intervention, or intermittent claudication).Exploratory objectives include comparing acute exercise responses (prescribed exercise training load, actual training load, exercising heart rate and rating of perceived exertion) between PAD and CAD patients.
The background for performing the present study is to compare the mass calculations by CT scanning and by invasive absolute blood flow measurements and thereby corroborating both methods.
This randomized, multicenter, prospective study seeks to compare left radial and femoral access during cardiac catheterization of patients with prior history of CABG surgery, with the primary objective of demonstrating that the two access techniques do not differ in the net procedure time (non-inferiority study) expanding the documented benefits of radial access to this group of patients.
We evaluated the effectiveness of a combination of a comprehensive health assessment consisting of the combination of a screening full body scan employing graphic patient education and motivational techniques followed by intensive, individualized behavioral training and management program on improved adherence to beneficial lifestyle behaviors, as well as possibly reduced risk of disease.
Flaxseed consumption has beneficial effects on cardiovascular risk factors. In addition, the benefit of the Mediterranean-like diet in primary and secondary prevention of cardiovascular diseases has been shown.The purpose of this study is to investigate the effects of flaxseed consumption, alone and in combination with the Mediterranean-like diet, in adjunct to conventional medical treatment, in improving vascular endothelial function, plasma lipid profile and high sensitivity c-reactive protein of coronary artery disease (CAD) patients.
