Read our Heart Failure research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether patients preparing for heart surgery benefit from extra education, exercise training, and personalized communication before and after their operation. Researchers want to know if traditional methods like phone calls and written materials work better than a new mobile app approach for keeping patients informed and supported throughout their surgical journey.
Heart surgery can be overwhelming and stressful for patients. This study exists to find the best way to prepare patients beforehand and support them during recovery—aiming to reduce complications, improve healing, and help patients feel more confident and secure throughout the process.

You would be randomly assigned to one of three groups: standard care with minimal contact, extra education and phone support with exercise training materials, or extra education through a mobile app with two-way communication. Before surgery, you may receive respiratory and exercise training tailored to your needs. After surgery, your group would receive different levels of follow-up communication—either traditional phone calls or through a mobile app—to track your recovery and answer questions.
