Pfizer is conducting a study to recruit 120 participants with heart failure symptoms in three ranges based on the New York Heart Association Functional Classification, or NYHA:
- people with slight limitation to activity and mild symptoms such as fatigue, palpitations and shortness of breath during physical activity but who have no symptoms while resting.
- people with more severe limitations to physical activity but who are comfortable at rest and
- people who cannot undergo physical activity without discomfort and who have symptoms of heart failure even at rest.
There will be a total of 6 in-clinic visits over the course of one year. Participants will visit the site at their first visit, and then again after 1 month, 3 months, 6 months, 9 months, and 12 months. At each visit, the participants will complete activities to help measure their physical function and will also complete questionnaires about their symptoms and quality of life. At the end of each visit, participants will also be sent home with a digital health technology, or DHT, to assess physical activity and symptoms in between clinic visits.
