Hypotension in Heart Failure is Less Harmful if Associated with High or Increasing Doses of Heart Failure Medication: Insights from the Swedish Heart Failure Registry
Main finding · CVD/HFH per 10 mmHg higher baseline SBPResult — go to the resultAdjusted hazard ratio 0.92 95% CI 0.92–0.93Authors' conclusion
The association of lower SBP with higher risk of CVD/HFH is attenuated in patients with optimized HF medication.
Study context
- Population
- Patients with HF with reduced ejection fraction (HFrEF) in the Swedish heart failure (HF) registry (2000–2018)median age 74.0
- Participants
- 42,040 patients
- Exposure
- Association of systolic BP (SBP) with outcomes by HF medication dose
- Outcome
- CV death and/or HF hospitalisation (cardiovascular death (CVD)/HF hospitalization (HFH))
Methodological detailsSwedish HF registry
- Swedish HF registry
Main finding
CVD/HFH per 10 mmHg higher baseline SBP
Adjusted hazard ratio

Per 10 mmHg higher SBP, as printed
As reported in the abstract
- Event-rate decrease per 10 mmHg SBP increase, untreated patients
- 10%
- Event-rate decrease per 10 mmHg SBP increase, patients at maximum renin-angiotensin system (RAS) inhibitor and beta-blocker dose
- 7%
Observational data: associations, not effects.
