Chronic Heart Failure
- What is missing?
Prospective Randomized Studies!
- GFR 15-45 ml/min below 30 ml/min!)
- Planned with Patiromir (SAPPHIRE; DIAMOND)
- Spiro plus Patiromir vs. Standard treatment
Baseline heart rate is a predictor of endpoints on placebo

PARADIGM-HF: Safety
Class I:
Evidence and/or general agreement that a given treatment is beneficial,
useful and effective.
What can the Guideline Committee Do?
Evidence A:
Data derived from multiple randomised clinical trials or meta-analyses.
Evidence B:
Data derived from a single randomised trial or multiple non-randomized
studies ("registry trials") or a single metaanalysis
