Clinical trials

The goal of this clinical trial is to evaluate the feasibility of a cardiac pre-hab program for patients with blocked arteries (CTO) who are referred for PCI treatment. The main questions it aims to answer are: Can the pre-hab program improve patients\' functional capacity before PCI? Does the pre-hab program impact the need for PCI based on improvements in patients\' health? Participants will: Undergo an initial assessment including a physical exam, medication history, quality of life questionnaires, and blood work. Complete a 6-month cardiac rehabilitation program. Have repeat assessments to evaluate improvements and determine if PCI is still needed. If PCI is performed, be assessed again one month later for functional capacity improvements. If PCI is not needed after 6 months, participants will be followed virtually for an additional 5 months.
