Abstract/OtherAbstract:
Using echocardiographic and Doppler methodology, we evaluated the effects of celiprolol 200-400 mg/day and metoprolol 100-200 mg/day, given for one year, on haemodynamics, left ventricular structure and function, and aortic root distensibility in 40 hypertensive patients. Total peripheral resistance was unchanged with metoprolol (-1.7%) but decreased with celiprolol (-11.2%), a significant difference between the two treatments (P = 0.01). Left ventricular mass index was reduced by 5.7% in those patients receiving metoprolol and by 11.8% in those receiving celiprolol (P < 0.001). Cardiac index fell significantly with metoprolol and marginally with celiprolol (-13.9% vs. 5.9%, P = 0.003). Left ventricular diastolic function-as shown by the transmitral early to late peak filling velocity ratio-was not altered with metoprolol, but a significant increase (17%, P = 0.2) was seen with celiprolol. Both metoprolol and celiprolol increased aortic root distensibility, with celiprolol having a significantly greater effect (80% vs. 30%, P < 0.01). We conclude that, in comparison to metoprolol, long term antihypertensive therapy with celiprolol improves left ventricular diastolic and aortic root function, whilst reducing total peripheral resistance and left ventricular hypertrophy.
