Filter by:Background: Exercise-based cardiac rehabilitation (CR) is the gold-standard in tertiary prevention of coronary artery disease (CAD), yet average CR attendance is only 67%. Patient education is commonly delivered during CR to impart information about CAD and its risk factors. An underlying assumption is that knowledge will enhance patients' attitudes toward CR, promote better program adherence, and improve clinically relevant cardiovascular outcomes. However, more formative work is needed to characterize the impact of patient education delivered in a CR setting on purported mechanisms-of-action in order to optimize efficacy. Few cardiac patient education interventions have been empirically validated, and it is unclear whether knowledge gains from education translate to improved CR attitudes and program adherence. Objective: This study aims to 1) examine the association between cardiac patient education and changes in knowledge about CAD, and; 2) explore whether changes in knowledge correspond to (a) improved attitudes about CR (perceived necessity, concerns about exercise, practical barriers, perceived personal suitability), and (b) increased CR adherence. Hypothesis: It is expected that 1) knowledge will increase from pre- to post-patient education, and 2) knowledge gains will be associated with improved CR attitudes and better CR adherence. Methods: 100 adults with CAD referred to outpatient CR will be recruited prior to attending four, mandatory 2.5-hour-long group-based education classes. Patients will subsequently attend supervised CR exercise sessions twice-weekly for 12 weeks. Validated questionnaires assessing knowledge about CAD and attitudes toward CR (i.e., perceived necessity, exercise concerns, barriers, perceived suitability) will be completed pre- and post-cardiac education classes, and 12-weeks post-CR. Adherence (# of CR exercise sessions attended) will be obtained by chart review. Implications: This study will help identify whether patient education delivered in a CR setting impacts hypothesized treatment targets and inform future efforts to optimize behavioral interventions for increasing CR utilization
The purpose of this study is to investigate the change of total cholesterol content of erythrocyte membranes (CEM) in patients with coronary artery disease treated with secondary prevention drugs, and the correlation with the prognosis.
The investigators present an interesting co-incidence of Gated wall abnormality in the inferolateral wall in normal sestamibi myocardial perfusion images with J wave in the inferior derivations of the ECG in a patient. The subsequent coronary angiography demonstrated 80% mid right coronary artery (RCA) stenosis, which was intervened with a drug-eluting stent. The investigators conclude that even though the myocardial perfusion is normal, the association of gated wall abnormality with J wave presentation within the same location should be further evaluated.
It is a single arm clinical evaluation of safety and efficacy of the Medtronic Resolute Onyx™ zotarolimus-eluting coronary stent system in subjects who are eligible for percutaneous transluminal coronary angioplasty (PTCA) in de novo lesions amenable to treatment with Resolute Onyx™ Stent System in China.
How safe and effective are CD34+ cell intracoronary injections for treating coronary endothelial dysfunction (CED)?
Prospective, multicenter, single arm registry to monitor post-market clinical outcomes of patients treated with Inspiron Sirolimus-Eluting Stent with Biodegradable Polymer.
The PACO trial is a randomized clinical trial conducted in Heart Centers of Kuopio and Turku university hospitals. The coronary artery disease, aortic valve stenosis and mitral valve insufficiency patients preparing for elective coronary artery bypass grafting (CABG), aortic valve replacement (AVR) or mitral valve repair (MVR) will be randomized to either intervention or control group. The specific operation groups (CABG, AVR and MVR) will be analyzed separately. The 7-day baseline measurements of sedentary behaviour (SB), physical activity (PA) and sleep will be conducted to the patients by using the RM42 accelerometer during the pre-operative month. After the cardiac procedure is completed and the patient is moved to post-operative ward, the control group patients will begin the standard post-operative rehabilitation program of the participating hospitals (activity guidance given by a physiotherapist). Patients in the intervention groups will follow the identical program but after discharge they will also receive personalized activity guidance through the combination of ExSed smart phone application, Suunto MoveSense accelerometer and cloud system during the first 90 days of post-operative rehabilitation. Weekly evolving daily goals to replace SB with PA (daily goals for steps, moderate PA, light PA and standing, and sitting time limit) will be designed for each patient of the intervention groups. A new daily step goal will be delivered from the cloud system to the patient's smart phone in the beginning of each week of the intervention. The daily step goal of the first intervention week is based on patient's walking distance assessed by a physiotherapist in post-operative ward. The following goals will be automatically evolved in the basis of patient's personal average step count of the previous week. The MoveSense accelerometer will measure accumulated levels of SB, PA and sleep, and transmit the data to user's ExSed application with Bluetooth. With information about accumulated levels of SB and PA, the application is able to guide the patient to accomplish the predefined activity goal. The guidance and motivation will be offered with pop-up notifications and histograms (columns are fulfilled according to patient's accumulated daily activity). The researches retain a remote access to the activity data of patients in the cloud system. The ExSed application will be connected to the cloud system with internet connection. In addition, the patients of the intervention groups will receive short video files (lasting from 1 to 3 minutes) containing exercise guidance from a physiotherapist specialized to cardiac operation patients. These videos are available on the ExSed application during the intervention. The physiotherapist will also contact each patient (by mobile phone) with structured contact form from 1 to 4 times in a month to make sure that the intervention is proceeding as designed.
The aim of this Real-world study in China is evaluating the Safety and Efficacy of Paclitaxel Eluting Balloon Catheter in Coronary de-novo lesions(target vessel diameter:2.5mm-4.0mm)Treatment. And the primary point of this study is the target lesion failure of 12 months after surgery.
Pre-habilitation programs that combine physical training, nutritional support and emotional reinforcement have demonstrated efficacy as presurgical optimization strategies in the context of digestive surgery. The experience in patients at risk for cardiac surgery, one of those associated with higher morbidity and mortality, is anecdotal. Main objective: to evaluate the feasibility, efficacy and cost-effectiveness of a pre-habilitation program for the improvement of preoperative functional capacity in high-risk and intermediate risk groups for cardiac surgery and its impact on the reduction of postoperative complications (primary endpoint). Secondary objectives: (i) in-hospital stay; (ii) symptoms, quality of life, (iii) evaluation of information and communication technologies (ICT) as a support for the pre-habilitation, and (iv) design and validation of indicators for a future large-scale implementation of this type of intervention. Design: Subproject: #1: Prospective study of the efficacy of prehabilitation in heart transplant candidates during the study period. The results will be compared with historical records; #2: Randomized controlled trial with a 1:1 ratio to assess the efficacy of prehabilitation in patients undergoing elective coronary revascularization or valve replacement surgery. Subjects: Subproject #1: 40 patients candidates for heart transplantation. Subproject #2: 80 patients in the prehabilitation group and 80 controls in which a conventional treatment will be performed. Intervention: (i) personalized supervised resistance training, and (ii) program to promote physical activity and healthy lifestyles. The overall duration of the intervention is estimated to be at least 4-6 weeks (variable in each subproject). The support with ICTs will be a significant aspect of the program in which the adaptation of the personal health folder of Catalonia (Cat@SalutLaMevaSalut) will be fundamental.
