Implication
Supports ePAD monitoring to anticipate decompensation across HF phenotypes; leaves open whether pressure-guided strategies improve outcomes.
Key Points
- This study aims to clarify the pathophysiological differences between systolic and diastolic heart failure.
- Patients were divided into two groups: systolic heart failure (EF <50%) and diastolic heart failure (EF ≥50%).
- Utilized echocardiographic and implantable hemodynamic monitor data for assessment.
- Measured various cardiac parameters including ejection fraction and diastolic pressures.
- DHF patients had significantly better EF (58±8%) compared to SHF patients (24±10%, P<0.05).
- Acute decompensated HF events increased ePAD for both groups (DHF from 17±7 to 22±7 mm Hg; SHF from 21±9 to 24±8 mm Hg, P<0.05).
- Structural and functional differences highlight the importance of diastolic pressures in heart failure pathophysiology.
Structured PICO
P
Population
274 patients with chronic heart failure, divided into systolic HF (EF <50%, n=204) and diastolic HF (EF ≥50%, n=70).
O
Outcome
Changes in estimated resting pulmonary artery diastolic pressure (ePAD) and other hemodynamic/echocardiographic parameters during transition from chronic compensated to acute decompensated HFsurrogate
Elevated diastolic pressures play a pivotal role in the transition from chronic compensated to acute decompensated heart failure in both systolic and diastolic HF patients.
