The present study was undertaken to clarify whether celiprolol and atenolol, β1-selective β blockers with and without intrinsic sympathomimetic activity (ISA), respectively, might improve ischemic damage in the isolated perfused hearts of spontaneously hypertensive rats (SHR), and whether long-term treatment with celiprolol may reduce left ventricular hypertrophy (LVH) in patients with essential hypertension. Atenolol (50mg/kg/day) or celiprolol (300mg/kg/day) for 7 weeks significantly reduced the blood pressure in SHR to the same degree, and both drugs decreased the heart rate, but the magnitude of the fall in heart rate was significantly higher with atenolol treatment than with celiprolol treatment. Both treatments significantly reduced the ratio of LV weight to body weight in SHR and significantly improved the coronary reserve in SHR to the same extent. Both treatments significantly improved the extent of recovery of the pressure-rate product and the extent of percent recovery of the coronary flow after reperfusion following 30min of ischemia in SHR. Celiprolol treatment in patients with essential hypertension for 12 months significantly decreased interventricular septal thickness (IVST)+LV posterior wall thickness (PWT) and LV mass index (LVMI), but there was no significant correlation between IVST+PWT or LVMI and blood pressure before and after treatment. IVST+PWT and LVMI were significantly decreased after 3 months of treatment and these LVH indices were significantly smaller after 6 and 12 months of treatment than after 3 months of treatment. In conclusion, both celiprolol and atenolol treatment reduced LVH and improved the ischemic damage in SHR. In essential hypertensive patients with LVH, celiprolol treatment effectively reduced blood pressure and achieved LVH regression. (Hypertens Res 2000; 23: 467-474)
