Heart Failure, Mitral Regurgitation
Conditions
Brief summary
This observational study is to develop and validate the prediction model for functional mitral regurgitation regression in heart failure patients taking GDMT. The patients diagnosed ≥2+ functional mitral regurgitation by ultrasonic cardiogram are enrolled in this study and would be clinically followed by at least one year (clinical visit at 3 months, 6 months, and 12 months), and then by when the endpoints are reached.
Interventions
Guideline-directed Medical Therapy (GDMT) includes those 4 drugs, and only taking at least 3 drugs could be recognized as GDMT.
The prediction model of FMR regression would be developed to recognize patients whose FMR would regress due to GDMT, and consequently help determine the treatment.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| FMR regression rate | 3 months | the rate of FMR regression by at least 1 grade by 3 months |
Secondary
| Measure | Time frame | Description |
