Methodology The PAMP project phase II, as a component of CARDIECOL program will be implemented by designing a pilot study, a randomized controlled trial. Adult-patients with greater than or equal to 30 years old entering elective non-cardiac surgery, prior informed consent will be randomized to an intervention prescribed of walking in the period of 2-3 weeks before surgery or will be assigned to a Control group/conventional care. The study was not blinded to patients, but evaluation and analysis of the data will be blinded for researchers and statisticians. Patients will be evaluated on their previous level of physical activity and will be evaluated by a physiatrist doctor for prescribing the walk (exercise). This study will include a sample of 500 patients, with capacity to mobilize, ability to walk at least 30 min/by day (150 min by week) for at least 1 week before surgery. Patients have to be hospitalized for at least 24 hours after the surgical procedure. Outcomes are length of stay, and time to first walk. Other results are evaluation falls during hospitalization and the presence of falls, report of cardiovascular events, and death by group.
