Abstract:
:The aim of the study was to compare the changes in plasma renin activity induced by a vasodilator in normal dogs and in dogs with an impaired cardiac reserve. In normal conscious dogs, a 60-min nitroprusside infusion increased plasma renin activity from 1.05 +/- 0.26 to 8.35 +/- 1.20 ng, angiotensin I ml-1 h-1 (P less than 0.002) and heart rate from 83 +/- 6 to 149 +/- 15 beats/min (P less than 0.002). In five dogs in which a aortocaval fistula had been created 4 weeks earlier, the same infusion still increased plasma renin activity but significantly less than in normal dogs (0.90 +/- 0.29 to 4.44 +/- 0.64 ng ml-1 h-1; P less than 0.01) and the heart rate was unchanged (134 +/- 4 to 139 +/- 7 beats/min; NS). Similarly, in five dogs with a previous myocardial infarction, the heart rats response to nitroprusside was blunted (108 to 107 beats/min;NS) and plasma renin activity increased less than in normal dogs. Plasma renin activity also increased acutely after hydralazine administration in dogs which myocardial infarction (1.05 +/- 0.26 to 8.99 +/- 0.79 ng ml-1 h-1; P less than 0.05); after 1 week of hydralazine, plasma volume had increased from 54.9 +/- 0.9 ml kg-1 to 74.5 +/- 4.9 ml kg-1 (P less than 0.05) and plasma renin activity remained higher than control (4.66 +/- 0.66 ng ml-1 h-1; P less than 0.01). In conclusion, vasodilator therapy rapidly activates vasoconstrictor forces and fluid retention even in dogs with limited cardiac reserve. Although the regulation of plasma renin secretion appears altered in these models of heart disease, the renin response remains sufficient to seriously limit the beneficial effects of vasodilator therapy.
