Abstract:
Objective To observe the effect of heat stress on plasma cGMP and hemodynamics in animals with chronic heart failure. Methods Coronary arteries of twenty-five rabbits were ligated to set up the animal model of heart failure and other five rabbits only received thoractomy as sham group. Eight weeks after coronary artery ligation, they are randomly divided into heat stress (HS) group, control group, HS+L-NAME group, and non-HS+L-NAME group and non-HS+L-Arg group, each group containing 5 animals. Hemodynamic indices and plasma levels of NOS and cGMP were measured. Results Hemodynamics of all 25 rats received operation was poorer compared with the rats of sham group (P
