Smartphone Based Tele-rehabilitation on Functional Capacity and Sleep Quality Among Coronary Heart Disease Patients.

Primary outcomes

1. Pittsburgh Sleep Quality Index

   Time frame: 8 week

   The Pittsburgh Sleep Quality Index (PSQI) is a self-rated questionnaire which assesses sleep quality and disturbances over a 1-month time interval. Only self-rated questions are included in the scoring. The 19 self-rated items are combined to form seven "component" scores, each of which has a range of 0-3 points. In all cases, a score of "0" indicates no difficulty, while a score of "3" indicates severe difficulty. The PSQI has a high test-retest reliability and a good validity for patients with cardiac patients. Changes from the baseline will be measured.

2. Duke Activity Status Index

   Time frame: 8 week

   The Duke Activity Status Index (DASI) is an assessment tool used to evaluate the functional capacity of patients with cardiovascular disease (CVD), such as coronary artery disease, myocardial infarction, and heart failure. In clinical practice, DASI can be used to assess the effects of medical treatments and cardiac rehabilitation as well. Positive responses are summed up to get a total score, which ranges from 0 to 58.2. Higher scores would indicate a higher functional capacity. Changes from the baseline will be measured.

3. 6 Minute walk test

   Time frame: 8 week

   six-minute walk test as a measure of functional status or fitness Before you begin to walk, the researchers will take a participant's blood pressure, pulse, and oxygen saturation using a pulse oximeter. Participants will get the instructions below. For six minutes, the contestants will walk as far as they can. to a chair or cone at your usual speed, then turn around. and will keep going back and forth for another six minutes. Distance will be measured in meters. Changes from the baseline will be measured.
