Filter by:Auditory motor-coupling has been shown to induce neural-entrainment that can synchronize walking-pace with sonic tempo. The extent to which acoustical-motor entrainment can induce longer-term changes to physical activity behaviours remains unclear. Cardiac rehabilitation is essential and is associated with irrefutable mortality benefits for patients following an acute cardiac event. Randomized clinical trials have demonstrated a 25-50% improvement in survival as compared to controls; however, as many as 50% of patients will dropout of such programs prior to completion, which undermines these morbidity and mortality benefits (37; 54). Research exploring ways to improve compliance to such programs has suggested that the incorporation of music and other such holistic, patient-centered interventions into a rehabilitation/exercise program is associated with improved motivation, endurance and satisfaction amongst cardiac rehabilitation participants. The MAINTAIN study has been designed to conduct a feasibility evaluation on the effects of a preference-based music intervention on adherence to the cardiac rehabilitation program at Toronto Rehabilitation Institute. The primary objective of the trial is to evaluate the feasibility of the implementation of such a protocol within the context of the program. This is a two-arm, block 2:1 randomized trial. 35 patients participating in cardiac rehabilitation at Toronto Rehabilitation: Cardiac Rehabilitation and Secondary Prevention Program will be recruited and participants will be randomized into: 1) control (standard, usual care); and, 2) music intervention. The randomization process employed will be a blocked 2:1 strategy, whereby subjects are randomized to the music treatment arms 2:1. All those patients randomized into arm 2 will be equally randomized into either (2) preference-based music intervention, (3) preference-based music enhanced with RAS. The primary outcome measure will be weekly physical activity over a 3 month duration as measured using tri-axial accelerometers. We will also analyze the impact of a preference-based music intervention based on audio playlist utilization, self-reported sitting times ,exercise-times, on-site attendance to the cardiac rehabilitation program (attendance), peak oxygen uptake (VO2) (stress-test), and self-efficacy levels (self-efficacy questionnaires). These measures will be collected and analyzed throughout the course of the intervention (3 months).
The goal of this study is to use MCE (myocardial contrast/perfusion echocardiography) to study and compare short/long term change of myocardial perfusion abnormality and cardiac outcome in diabetic patients after nonfatal MI (heart attack), who are treated with different glucose control agents.
This study is about rehabilitation of arm function after a stroke. The investigators are testing the dosage of therapy that is needed for meaningful recovery of arm and hand function. Dosage of therapy refers to the amount of time (in this case, the total number of hours) that a person participates in treatment. The investigators hope to learn how much therapy time is needed in order for change to occur in arm and hand function after a person has had a stroke. Eligible candidates must have had a stroke affecting the use of an arm or hand at least 6 months ago.
The purpose of this study is to determine whether intra-coronary adenosine or sodium nitroprusside (SNP) delivered selectively via a thrombus aspiration catheter (or if unsuccessful via a coronary microcatheter) following thrombus aspiration in Primary Percutaneous Coronary Intervention (P-PCI) reduces microvascular obstruction (MVO) parameters and infarct size as measured with cardiac MRI, compared with standard treatment following thrombus aspiration in patients presenting with ST-elevation myocardial infarction (STEMI).
To determine whether, on a background of optimal medical therapy, including ticagrelor, opening of all suitable narrowings or blockages found at the time of primary PCI for an acute heart attack is better than treating only the culprit lesion in patients with multi-vessel disease.
The aim of this study is the evaluation of early smoking reduction or cessation by means of no nicotine electronic cigarette added to standard counselling.
Physical exercise training appears effective for low to moderate patients assigned to cardiac rehabilitation. However, adherence to cardiac rehabilitation is low and physical activity levels often drop after attending the last supervised rehabilitation session. This study will compare home based physical exercise training including telemonitoring with regular centre based physical exercise training. Main outcome measures are the change in physical activity and the change in physical fitness (peak Oxygen uptake) after the initial rehabilitation period (12 weeks) and after 1 year. Secondary outcome measures are cost-effectiveness, training adherence, health-related quality of life and patient satisfaction.
During primary PCI, stent deployment and post-dilatation are associated with no-reflow. The mechanisms for no reflow include distal embolization of thrombus, enhanced thrombus formation and vascular spasm. No reflow is associated with risk factors such as prolonged duration of ischaemia, heavy thrombus burden, persistent ST elevation and long stent length. ACTIVE HYPOTHESIS: once normal antegrade flow has been re-established with initial aspiration thrombectomy and/or balloon angioplasty at the beginning of primary PCI, compared with usual care with direct stenting, a strategy of deferred stenting for 4 -16 hours to permit the beneficial effects of normalized coronary blood flow and anti-thrombotic therapies will reduce the incidence of no reflow in at-risk STEMI patients. DESIGN: In consecutive STEMI patients with risk factors for no reflow and who have given informed consent, when normal flow has been established (TIMI 3) by initial aspiration thrombectomy and/or balloon angioplasty, participants will be randomized to deferred stenting or usual care with direct stenting. All patients will receive dual anti-platelet therapy. Patients who are randomized to deferred stenting will receive intravenous glycoprotein IIbIIIa inhibitor and anti-coagulation with low molecular weight heparin. Patients who are screened and not eligible to be randomized will be prospectively entered into a registry. Study assessments for feasibility, safety and efficacy will be prospectively performed. An independent clinical event committee will review all serious adverse events. Study endpoints will be subject to core laboratory analyses. The study is intended to inform the design of a larger multicentre clinical trial.
Overall, the investigators aim to recruit 150 subjects during their hospitalization for an acute coronary syndrome (ACS). At two weeks post-ACS, the investigators will assess levels of gratitude and optimism, draw blood for baseline levels of biomarkers, gather baseline information about health behaviors critical to cardiac health, and obtain baseline measures of symptoms and function. Finally, the investigators will repeat assessments of biomarkers, behavior, and function at 6 months to allow us to assess the impact of gratitude and optimism on these outcomes; the investigators will also have an objective measure of physical activity via accelerometer (step counter) at 6 months. Specific Aim #1: To prospectively assess the association between gratitude/optimism 2 weeks after ACS and improvement in biological markers of cardiac health at 6 months post-ACS. Hypothesis: Higher levels of gratitude/optimism at 2 weeks will be associated with greater reductions in levels of biomarkers associated with negative heart health between 2 weeks and 6 months. Specific Aim #2 (*primary aim*): To assess the association between gratitude/optimism 2 weeks after ACS and subsequent adherence to health behaviors known to improve post-ACS prognosis at 6 months. Hypothesis: Higher levels of gratitude/optimism at 2 weeks will be associated with greater amounts of physical activity (measured by accelerometer) at 6 months (primary study outcome measure), and greater improvements in self-reported adherence to health behaviors (activity, diet, and medication) between 2 weeks and 6 months. Specific Aim #3: To assess the association between gratitude/optimism at 2 weeks and non-elective cardiac rehospitalizations (and other clinical outcomes) at 6 months. Hypothesis: Higher levels of gratitude/optimism at 2 weeks will be associated with greater improvements in depression, health-related quality of life, function, cardiac symptoms, and possibly readmissions, between 2 weeks and 6 months.
The association between obesity and cardiovascular disease (CVD) has mostly been studied using broad endpoints or have focused on cause-specific mortality. The investigators aim to compare the effect of body mass index (BMI) on different types of initial presentation of CVD.
