An abbreviated exercise right heart catheterization protocol for the diagnosis of heart failure with preserved ejection fraction
Listen to this summary
The authors aimed to determine if a 3-minute abbreviated exercise right heart catheterization (eRHC) protocol could accurately diagnose heart failure with preserved ejection fraction (HFpEF) compared to the standard peak exercise protocol. Their findings demonstrated that the abbreviated protocol had good sensitivity (85%) and specificity (85%) for diagnosing HFpEF, with strong correlations in hemodynamic measurements, suggesting it could enhance the accessibility and efficiency of HFpEF diagnosis without compromising accuracy.
