Background: The effects of α and ß adrenergic receptor modulation on the risk of developing heart failure (HF) remains uncertain due to a lack of randomized controlled trials. This study aimed to estimate the effects of α and ß adrenergic receptors modulation on the risk of HF and to provide proof of principle for genetic target validation studies in HF.
Methods: Genetic variants within the cis regions encoding the adrenergic receptors α1A, α2B, ß1, and ß2 associated with blood pressure in a 757,601-participant genome-wide association study (GWAS) were selected as instruments to perform a drug target Mendelian randomization study.
MicroRNA (miRNA) inhibition is a promising therapeutic strategy in several disease indications. MRG-110 is a locked nucleic acid-based antisense oligonucleotide that targets miR-92a-3p and experimentally was shown to have documented therapeutic effects on cardiovascular disease and wound healing. To gain first insights into the activity of anti-miR-92a in humans, we investigated miR-92a-3p expression in several blood compartments and assessed the effect of MRG-110 on target derepression.

However, its relation with mid and long-term prognosis as well as the impact of Ejection Fraction (EF) is unknown. Our objective was to study the relationship between long-term survival and HR at admission depending on EF in a cohort of patients hospitalized for AHF.
