Hypertensive Heart Failure with Preserved Ejection Fraction: Guidelines vs. Randomized Controlled Trials Evidence Gaps

Hypertension is among the most important modifiable risk factors associated with heart failure with preserved ejection fraction (HFpEF) development and progression, yet guideline-directed blood pressure (BP) targets (<130/80 mmHg) and sodium–glucose co-transporter 2 inhibitor (SGLT2i) therapies lack dedicated randomized controlled trials (RCTs) in this specific group of patients. This narrative review synthesizes 2024 ESC/ESH and 2025 JSH meta-analyses, discussing the proposed pathophysiological framework linking hypertension-associated remodeling with HFpEF. Post hoc analyses from landmark trials (EMPEROR-Preserved, DELIVER) demonstrate consistent heart failure (HF) event reductions with SGLT2i (pooled HR 0.79, 95% CI 0.67–0.93), complemented by modest systolic BP lowering (−2.3 mmHg) and biomarker insights. Soluble ST2 and N-terminal pro-B-type natriuretic peptide (NT-proBNP) may contribute to risk stratification in HFpEF populations when interpreted in conjuction with imaging findings and clinical context; however, neither biomarker is specific for hypertension-mediated remodeling. Critical evidence gaps persist: heterogeneous BP thresholds across international guidelines, limited device therapy data (renal denervation showing −8.5 mmHg sustained reduction), and real-world implementation barriers among elderly/comorbid Europeans (adherence < 50%, polypharmacy risks). Hellenic HF Registry data highlight frailty prevalence (68% in patients > 75 years) complicating aggressive BP management. The review addresses phenotype-specific challenges through precision medicine approaches incorporating phenomapping and multi-biomarker panels (NRI 0.28 improvement). We advocate for dedicated HFpEF RCTs evaluating intensive vs. standard BP targets, SGLT2i sequencing with antihypertensives, and European real-world registries to bridge the translational gap. These strategies aim to transform guideline recommendations into optimized, patient-centered care for the rapidly expanding hypertensive HFpEF population.
