Normotensive, Sprague-Dawley (S-D) and spontaneously hypertensive (SH) rats were subjected to aortic ligature. The systolic blood pressure of S-D rats was increased by +/- 80 mm Hg, whereas the blood pressure of SH rats with pre-existent hypertension increased only slightly, +/- 9 mm Hg. The S-D rats developed myocardial and renal infarcts as well as polyarteritis nodosa; the SH rats developed testicular and microadrenocortical infarcts only. Aortic-ligated S-D rats had elevated creatine phosphokinase, serum glutamic-oxaloacetic transaminase, serum glutamic-pyruvic transaminase, and lactic hydrogenase levels and manifested hyperglycemia, hypercholesterolemia, and elevated blood urea nitrogen (BUN) levels. Corticosterone levels increased in aortic-ligated S-D rats but decreased in SH rats. Collateralization about the site of aortic ligature appeared to be the same in both strains. It is suggested that the acutely induced hypertension in S-D rats rather than SH rats and differences in adrenal steroidogenesis between the two strains would best account for the dichotomous cardiovascular response to aortic constriction.

Angiotensin receptor blockers provide cardiovascular protection in heart failure patients. We have studied the effect of 8 weeks treatment with telmisartan (5 mg kg(-1) day(-1)) on cardiovascular complications associated with streptozotocin (STZ) diabetic rats. Wistar rats were made diabetic with STZ (45 mg kg(-1), iv). Various biochemical and cardiac parameters were measured at the end of 8 weeks. STZ produced hyperglycemia, hypoinsulinemia, hyperlipidemia, increased blood pressure, increased creatinine, cardiac enzyme and C-reactive protein (CRP) levels, reduction in heart rate and cardiac hypertrophy. Chronic treatment with telmisartan significantly (P < 0.05) prevented STZ induced hypertension and elevated fasting glucose level with simultaneous increase in serum insulin levels. It significantly (P < 0.05) reduced the elevated cholesterol, very low density lipoprotein (VLDL) and triglyceride levels in diabetic rats and increased the lower high density lipoprotein (HDL)-cholesterol levels. Further, telmisartan produced a significant (P < 0.05) reduction in the elevated creatinine levels, CRP and levels of other cardiac enzyme markers like Lactate de-hydrogenase and creatinine kinase of diabetic rats. STZ-induced bradycardia was also prevented by telmisartan treatment and it also produced beneficial effect by preventing cardiac hypertrophy as evident from left ventricular collagen levels, cardiac hypertrophy index and left ventricular hypertrophy index of diabetic rats. Our data suggest that telmisartan prevents not only the STZ-induced metabolic abnormalities, but also cardiovascular complications.
