NCT ID: NCT03466606 Recruiting - Clinical trials for Coronary Artery Disease

Implementation of a Trimodal Prehabilitation Program as a Preoperative Optimization Strategy in Cardiac Surgery

Start date: March 5, 2018
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03464331 Recruiting - Exercise Adherence Clinical Trials

Promoting Zero-time Exercise in Patients With Coronary Heart Disease

Start date: October 18, 2016
Phase: N/A
Study type: Interventional

Background Physical activity (PA), is an effective means of protecting against cardiovascular disease (CVD) development. PA refers to any skeletal muscle bodily movement that requires energy expenditure. Research shows that low- to moderate-intensity muscle endurance exercise, such as walking or brisk walking for about 15-20 minutes per day, is associated with a significantly lower CVD risk regardless of body mass index. Mobile technologies such as smartphone physical exercise apps offer a potentially cost-effective platform for facilitating regular exercise, allowing individuals to set goals, receiving feedback on achievements and health information for facilitating regular exercise. "Zero-time Exercise" (ZTE) is a new concept for physical activities (PA) and exercise promotion and can easily attract attention especially when most people believe that extra time is needed to do exercise. ZTE can be done easily during most time of day, while sitting, standing, walking or waiting. These include simple movements, such as stretching and resistance (endurance) movements of the head, neck and shoulders, chest and abdominal muscles and the upper and lower limbs. When ZTE is integrated into daily life and sustained with increasing intensity, the effects could be substantial, especially for those who are sedentary and have difficulties to meet the minimal requirements of 150 minutes of at least moderate PA per week. The term is also intended to motivate people to start with simple exercises (the 'Foot-in-the-door' approach), change the mindset (that exercises need much time, money and sweats) and overcome the inertia from a sedentary lifestyle to become more active. It could also be a way to promote mental health (such as increasing happiness) through PA or exercises and enjoying the fun and satisfaction from the rapid improvements in fitness performances. Having brought some easily observable benefits quickly to those who are willing to try for a few days, ZTE might lead to more intensive or vigorous exercises requiring extra time for greater benefits. Objective: To test the feasibility [recruitment, dropout, and adherence to PA] of using whatsapp as an inertia reminder to promote the adherence of Zero-time Exercises (ZTE) in patients with CHD.

NCT ID: NCT03462277 Recruiting - Clinical trials for Coronary Heart Disease

NCT ID: NCT03460938 Recruiting - Myocardial Ischemia Clinical Trials

Remote Ischemic Preconditioning and Postoperative Myocardial Ischemia

Start date: March 8, 2017
Phase: N/A
Study type: Interventional

High-risk abdominal surgery is frequently complicated by postoperative complications, such as sepsis, pneumonia or anastomotic dehiscence. Asymptomatic myocardial injury after abdominal surgery (MINS) predicts non-cardiac complications. The etiology of MINS in abdominal surgery patients is unknown. Remote ischemic preconditioning (RIPC) is a physiologic mechanism that exposes tissues to brief periods of non-lethal ischemia and reperfusion, creating resistence for future serious ischemic insults. RIPC in patients after cardiac or aortic surgery is associated with a protective effect on the heart. The effect of RIPC in abdominal surgery patients is unknown. Objective of the study: To determine the effect of RIPC on MINS in patients after pancreatic sugery. Study design: Randomised controlled parallel group mono-center pilot study. Study population: 90 adult patients scheduled for elective pancreaticoduodenectomy in St. Antonius Hospital (45 in the intervention group and 45 in the control group). Intervention: RIPC: 3 periods of 5 minutes of ischemia followed by 5 minutes of reperfusion are created by inflating a blood pressure cuff on the upper extremity after induction of anesthesia and prior to surgery. In the control group a non-inflated blood pressure cuff is placed on the upper extremity for 30 minutes. Primary study parameters/outcome of the study: Maximum postoperative concentration of high-sensitive cardiac troponin T. Secondary study parameters/outcome of the study: Markers of inflammatory, intestinal and renal injury, postoperative complications during 30 days, length of stay and hospital mortality.

NCT ID: NCT03440645 Recruiting - Clinical trials for Cardiovascular Risk Factor

Cardiovascular Screening for Family Members of People With Acute Coronary Disease

Start date: January 9, 2018
Phase: N/A
Study type: Interventional

Over a 12-month period, patients admitted with acute coronary disease to the cardiovascular care unit at the Jewish General Hospital (JGH), an academic tertiary care referral center in Montreal, Quebec, will be approached to refer first-degree relatives and/or household members age 18 years or older to an outpatient cardiovascular (CV) risk factor screening and treatment program. Relatives and household members will undergo a focused history, physical, and CV risk factor assessment and will receive evidence-based guideline-recommended treatment as indicated. Participants will be referred to nutritionists, smoking cessation programs, and to other allied healthcare professionals as needed. A follow-up visit at 6-months will assess treatment adherence and improvement in CV risk factors. All family and/or household members including the index patient will be encouraged to attend all healthcare visits together. The effectiveness of the screening strategy will be measured by the total number of participants identified as intermediate or high modified Framingham 10-year risk of cardiovascular disease. The effectiveness of the primary prevention intervention will be measured by the change in percentage of the mean modified Framingham 10-year risk score for participants between the initial visit and 6-month follow-up. The value of the referral, screening, and treatment program, as well as participant engagement and satisfaction will also be systematically evaluated.

NCT ID: NCT03438968 Recruiting - Clinical trials for Coronary Artery Disease

Women in Cardiac Rehabilitation: Optimizing the Training Response

Start date: August 24, 2017
Phase: N/A
Study type: Interventional

Cardiovascular disease (CVD) is highly prevalent in women resulting in 398,086 deaths annually. Even as women participate in traditional CR programs, data specificity and subsequent research have yet to emerge in a meaningful way so that women-centered CR can be better customized and their outcomes properly assessed. Aerobic fitness is a powerful predictor of prognosis in individuals with CVD yet there is evidence that women do not improve their peak VO2 as much as men during CR. We have designed a training program for women based upon past research with a goal of optimizing their training potential in CR. This program combines the utilization of a training technique termed high intensity interval training along with specific strength training exercises of the upper legs. We hypothesize that women, irrespective of age, would be capable of high intensity interval training to improve peak aerobic capacity in the CR setting. Furthermore, since women often have a deficit of thigh strength entering CR, and thigh strength correlates with endurance walking,strength training will also be included. The purpose of this study is to examine the value of high intensity interval training and strength training to maximize aerobic training response in CR for women. This may contribute to establishing specific protocols and training guidelines for future program design for women in CR. Since a set of comprehensive CR guidelines pertaining to women is lacking, it is hoped that the results of this study will help us develop exercise protocols and regimen to better structure and modulate CR programs for optimal benefit to women.
