Ventricular Assist Device

This multi-center, prospective, randomized, double-blinded, placebo-controlled study aims to investigate whether withdrawal of aspirin from the antithrombotic regimen in patients supported with the CH-VAD pump is non-inferior to the standard antithrombotic regimen of vitamin K antagonist combined with aspirin in terms of safety and efficacy.

Current international guidelines recommend that patients with a heart pump (left ventricular assist device, LVAD) participate in supervised exercise cardiac rehabilitation programs. However, not all patients with a heart pump are able to attend to a supervised program on a daily basis. The goal of this clinical trial is to determine whether a home-based exercise program helps patients with a heart pump improve their exercise capacity and quality of life, guided by telemedicine tools including a mobile app, smartwatch, and remote medical checkups. The study will also provide information about the safety of this program by monitoring for any issues or symptoms during home activity. The trial aims to answer the following questions: * Does a 12-week remote exercise program improve patients' exercise capacity? This will be measured using the 6-minute walk test and a cardiopulmonary exercise test. * Is it safe for patients to follow this exercise plan at home while being monitored through a mobile app and smartwatch? * Does the program improve quality of life and reduce feelings of anxiety or depression? This will be assessed using widely validated questionnaires, such as the Kansas City Cardiomyopathy Questionnaire. Researchers will compare the remote exercise program to standard care, which usually does not include exercise for patients who are unable to attend the hospital daily. Participants will: * Join the study voluntarily after signing a consent form. * Be randomly assigned, with a 50% chance of being in either the exercise group (following a structured plan with a mobile app) or the usual care group (receiving general written advice), to see which approach works best for recovery. * Follow a 12-week home-based routine if in the exercise group, including warm-up routine, walking or cycling, respiratory exercises, and light strength training, all supported by the mobile app, smartwatch, and professional monitoring. * Visit the hospital three times over six months for medical checkups, including walking and exercise tests, blood analyses, and questionnaires about physical and emotional health.

There are a variety of educational documents available to help in a participant's decision for VAD implant, however there is little information available to potential participants to help understand areas of satisfaction and concern following a VAD implant as various time points. The investigators want to provide better patient care through increased education and awareness beyond surgical outcomes and contribute to patient understanding of "what to expect" following a VAD implant. The investigators have created an anticipatory guidance (AG) tool based upon previous responses recorded in a local program's database, from the Quality of Life with a Left Ventricular Assist Device (QoLVAD) questionnaire. This questionnaire has five different domains (physical, social, emotional, cognitive thinking and spiritual/well-being). Investigators have previously analyzed responses to determine common areas of satisfaction and concern at 3-, 6-, 12- and 24-months post-VAD implant to better understand quality of life when living with a VAD. Investigators have had both VAD clinicians and VAD patients initially evaluate the tool to determine accuracy and effectiveness of the anticipatory guidance (AG) tool.
