Abstract

Abstract : Abstract: Long-chain non-coding RNA (lncRNA) Myosin Heavy Chain Associated RNA Transcripts (MHRT) are newly identified cardioprotective lncRNAs. In this study, we investigated the association of MHRT gene single nucleotide polymorphisms with risk and prognosis of chronic heart failure (CHF). Sanger sequencing was performed to detect the genotypes of rs3729830, rs7140721, rs76614781, rs3729829, rs3729828, rs3729825, and rs3729822 loci in the non-coding region of the MHRT gene from 240 patients with CHF and 240 control subjects. After 3 years of follow-up, progression-free survival was recorded in patients with CHF. The risk of CHF in subjects carrying A allele of the MHRT gene rs7140721 locus was 1.43 times higher than that of C allele carriers (95% CI: 1.23–1.62, P < .001). The risk of CHF in subjects carrying A allele of the rs3729829 locus was 1.41 times higher than that of G allele carriers (95% CI: 1.20–1.61, P < .01). The risk of CHF in the carriers of T allele of the rs3729825 locus was 1.89 times higher than that of C allele carriers (adjusted OR = 1.89, 95% CI: 1.66–2.04, P < .01). Further, the level of lncRNA MHRT in the plasma of subjects carrying CA/AA genotype of the rs7140721 locus was significantly higher than that of subjects carrying the CC genotype. The level of lncRNA MHRT in the plasma of subjects carrying GA/AA genotype of the rs3729829 locus was significantly higher than that of subjects carrying the GG genotype. In addition, the level of lncRNA MHRT in subjects with CT/TT genotype of the rs3729825 locus carriers was significantly higher than that in subjects with the CC genotype ( P < .05). In addition, significant differences in the mortality of patients with CHF were observed between different genotypes of rs7140721, rs3729829, and rs3729825 loci ( P < .001). The single nucleotide polymorphisms of MHRT gene rs7140721, rs3729829, and rs3729825 loci were associated with the risk of CHF and prognosis.
