Brief summary
Patients with advanced LVH and HFpEF will be randomly assigned in open-label fashion to receive LCZ696 titrated to 200 mg twice daily or valsartan titrated to 160 mg twice daily, and will be treated for 24 weeks.
Detailed description
Heart failure with preserved ejection fraction (HFpEF) has a significant morbidity and mortality, and therapies that have proven effective in HF with reduced EF have not been shown to improve long-term prognosis in HFpEF. Inhibition of circulating neprilysin could augment deficient NP-receptor GC signaling and therefore be beneficial in HFpEF, as suggested by the decrease in NP following administration of valsartan/sacubitril in the phase 2 (PARAMOUNT study). Use of valsartan/sacubitril is currently being tested in the multicenter PARAGON-HF trial with HFpEF patients. The investigators suppose the best candidates for LCZ696 therapy will be patients with HFpEF and advanced concentric LV hypertrophy and obesity, i.e. having the lowest BNP bioavailability.

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in left atrial volume index (LAVI) | 24 weeks | Difference in LAVI assessed by echocardiography between 24 weeks after baseline and at baseline |
| Change in average E/e' ratio | 24 weeks | Difference in E/e' ratio assessed by echocardiography both at rest and at peak exercise during diastolic stress test (DST) between 24 weeks after baseline and at baseline |
| Change estimated pulmonary artery systolic pressure (PASP) | 24 weeks | Difference in PASP assessed by echocardiography at peak exercise both at rest and at peak exercise during diastolic stress test (DST) between 24 weeks after baseline and at baseline |
| Change in left ventricular mass index (LVMI) | 24 weeks | Difference in LVMI assessed by echocardiography between 24 weeks after baseline and at baseline |
| Change of New York Heart Association (NYHA) functional classification | 24 weeks | Difference in NYHA class between 24 weeks after baseline and at baseline |
| Change in Minnesota Living With Heart Failure Questionnaire (MLHFQ) score | 24 weeks | Difference in MLHFQ score between 24 weeks after baseline and at baseline. The questionnaire is comprised of 21 important physical, emotional and socioeconomic ways heart failure can adversely affect a patient's life. After receiving brief standardized instructions, the patient marks a 0 (zero) to 5 scale to indicate how much each itemized adverse of heart failure has prevented the patient from living as he or she wanted to live during the past 4 weeks. The questionnaire is simply scored by summation of all 21 responses. Score ranges from 0 (best quality of life) to 105 (worst quality of life). |
