Objectives

Narrative objectives1

It remains unknown whether DNA methylation in peripheral blood cells is related to pathogenesis of Aortic Valve Stenosis(AS).
The aim of the present study was to perform an epigenome-wide association study (EWAS) for AS with two different groups (discovery and replicate), to identify AS-specific alterations in DNA methylation in peripheral blood mononuclear cells (PBMC). In addition, the present study evaluated the effects of surgical treatments on the levels of DNA methylation and its related transcription.

Results

EWAS revealed that DNA methylation of a CpG site differed significantly between the AS group and controls. The DNA methyltion level of chromosome 8 position 126448033, which is located at TRIB1 (tribbles homolog 1), was lower in the AS group than in the controls

Baseline Characteristics

There were no significant differences in the number of subjects, age and proportion of males between the AS group and controls in both discovery and replication studies. There were significant differences in blood pressure and lipid profile between the AS group and controls in both discovery and replication studies. There were significant differences in the prevalence of use of some medications including diuretics, beta-blockers, statins, angiotensin converting enzymes (ACEI), angiotensin receptor blockers (ARB) and calcium channel blockers (CCB) between the discovery and replication studies).

Participant flow

Peripheral blood was collected from patients with AS for baseline data before surgical treatment and again 12 months after surgical treatment (aortic valve replacement [AVR] or transcatheter aortic valve implantation [TAVI]) and from the controls.

Adverse events

no
