Longitudinal Blood Pressure and Cardiovascular Outcomes in Heart Failure: An Individual Patient Data Pooling Analysis of Clinical Trials
- Individual patient data pooled analysis of clinical trials
- time-dependent blood pressure (BP)
- multivariate Cox regression
Authors' conclusion
The relationship between BP and HF outcomes is non-linear and closely tied to left ventricular ejection fraction. Low SBP consistently predicts a poor prognosis, whereas high SBP is associated with an increased risk in HFmrEF and HFpEF but not in HFrEF.
Study context
- Population
- Patients with HF with reduced ejection fraction (HFrEF), HFmrEF or HFpEF in 8 clinical trials
- Participants
- 28,406 patients · 8 trials
- Comparison
- Low and high systolic BP (SBP) vs middle SBP
- Outcome
- Time to first CV death or heart failure (HF) hospitalization
