REVERSE-LVH: Role of ARNi in Ventricular Remodeling in Hypertensive LVH
Study Details
Study Description
Brief Summary
In Singapore, hypertension is very common in the adult population. Hypertensive heart disease is a leading cause of heart failure and cardiovascular death. Current management relies primarily on achieving blood pressure targets. However, the optimal blood pressure goals are controversial and there are inherent difficulties in measuring blood pressure using external devices applied to peripheral arteries. As a result of (usually longstanding) hypertension, the heart thickens (i.e. hypertrophies) to maintain function. Ultimately, HF may occur due to long standing energy deficits, muscle injury/death and diffuse interstitial fibrosis (heart muscle scarring). In an ongoing study (REMODEL, ClinicalTrial.gov Identifier NCT02670031), we have been able to undertake preliminary analyses with respect to factors associated with the development of fibrosis. In this randomize controlled trial, we will be examining a novel therapy that has the potential to induce regression cardiac hypertrophy and fibrosis.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Treatment Arm Entresto (valsartan/sacubitril) 100mg once a day |
Drug: Entresto
Entresto (Valsartan/sacubitril) 100mg once a day, up-titrating to 200mg or maximum 400mg to achieve target systolic blood pressure below 140 mmHg, over a duration of 52 weeks. If necessary, amlodipine and/or hydrochlorothiazide may be added to achieve target systolic blood pressure.
Other Names:

Active Comparator: Controlled Arm Valsartan 40mg once a day |
Drug: Valsartan
Valsartan 40mg once a day, up-titrating to 80 or maximum 160 mg to achieve target systolic blood pressure below 140mmHg, over a duration of 52 weeks. If necessary, amlodipine and/or hydrochlorothiazide may be added to achieve target systolic blood pressure.

Outcome Measures
Primary Outcome Measures
- Fibrosis volume [52 weeks]
Changes from baseline in fibrosis volume measured on CMR. Extracellular volume fraction (ECV) will be quantified from native and post-contrast myocardial T1. Fibrosis volume is defined as ECV x myocardial volume and indexed to body surface area (ml/m2)
Secondary Outcome Measures
- Left ventricular mass measured on CMR [52 weeks]
Changes from baseline in left ventricular mass, indexed to body surface area (g/m2).
- Biomarker/biochemistry [52 weeks]
Identify potential markers as indicators of cardiac structural effects of ARNi and ARB
