Does atrial natriuretic factor increase in response to an acute glucose load?
These observations demonstrate that, in normal humans, acute marked hyperglycaemia is accompanied by a rapid increase in circulating ANF levels. In this metabolic interaction, ANF might counteract the renal sodium-retaining effect of acute hyperglycaemia and hyperinsulinaemia.
Plasma homocysteine levels predict heart failure incidence in epidemiological studies. Transverse aortic constriction (TAC) induces pressure overload. Selective homocysteine-lowering gene therapy reduces mortality after TAC. Selective homocysteine lowering attenuates cardiac hypertrophy and fibrosis after TAC. Decreased homocysteine levels enhance diastolic function and lower oxidative stress.
