We evaluated nuclear factor kappa B {NFkB, rs28362491 [-94ins/delATTG (W/D)]} and angiotensin converting enzyme {ACE; rs1799752 [Ins(I)/Del(D)]} gene polymorphisms and their correlation with thyroid function in patients with heart failure (HF).
The DD allele frequency is lower in Chinese, but the M235T variant of the angiotensinogen gene is more common in Chinese than whites; it is not known to what extent polymorphisms of the renin-angiotensin system affect clinical status or prognosis in Chinese patients with heart failure.
