LVEF spectrum across two studies
As Dr. Mentz reported, the analysis included 881 and 466 patients from PIONEER-HF and PARAGLIDE-HF, respectively. Of the total, 673 were assigned to receive valsartan and 674 to receive either enalapril or valsartan. Overall, 36% of the population were women.
Patients in PIONEER-HF, with an LVEF 40% or lower, were started on their assigned drug during an acute-HF hospitalization and followed a median of 8 weeks. PARAGLIDE-HF patients, with LVEF higher than 40%, started therapy either in hospital (in 70% of cases) or within 30 days of their HF event; they were followed a median of 6 months.
Hazard ratios for outcomes in the sacubitril-valsartan group vs. those on ACE inhibitors or ARBs were 0.76; 95% CI, 0.69-0.83; P < .0001 for change in NT-proBNP levels. For the composite of CV death or HF hospitalization, HRs were as follows:
- 0.70 (95% CI, 0.54-0.91; P = .0077) overall.
- 0.59 (95% CI, 0.44-0.79) for LVEF < 60%.
- 1.53 (95% CI, 0.80-2.91) for LVEF > 60%.
Current guidelines, Dr. Mentz noted, recommend that sacubitril-valsartan “be initiated de novo” predischarge in patients without contraindications who are hospitalized with acute HF with reduced LVEF. The combined analysis of PIONEER-HF and PARAGLIDE-HF, he said, potentially extends the recommendation “across the ejection fraction spectrum.”
