Diabetes mellitus is associated with endothelial and cardiac dysfunction, and endothelin has been suggested to alter cardiac function by being a positive inotropic agent, modulating the Frank-Starling response, contracting the coronary arteries and inducing tissue proliferation. We investigated endothelin levels in diabetic and in healthy dogs, 1 and 3 days after placing arteriovenous shunts (8 weeks after diabetes induction) in the femoral regions. Right and left ventricular weight/body weight ratios and N-terminal-atrial natriuretic peptide were increased in shunted animals (P < 0.05). Plasma endothelin levels were comparable in healthy and diabetic dogs. Shunted circulation did not change systemic endothelin levels in healthy dogs but reduced endothelin levels in diabetic dogs. The functional significance of altered endothelin responses to acute hemodynamic burden in experimental diabetes needs further investigation.
