Long-term Effect of Different Antihypertensive Agents on Renal Hemodynamics / 中国康复理论与实践

ABSTRACT

@#ObjectiveTo investigate the long term effect of different antihypertensive agents on renal hemodynamics with ultrasound Doppler.Methods52 essential hypertensive patients were divided into three groups according to the antihypertensive agent they took angiotensin-converting-enzyme inhibitor (ACEI), calcium channel blocker (CCB) and β-adrenoceptor blocker (βB). The blood pressures of right upper arms were measured with mercury column blood pressure gauge using Korotkoff method. Renal hemodynamics were examined with ultrasound Doppler before and after treatment with agents. ResultsSystolic blood pressure (SBP) and diastolic blood pressure (DBP) of all patients were decreased significantly. An significant correlation was found between the deceases of blood pressure and the betterment of renal homodynamic parameters in ACEI and CCB groups, but not in βB group. ConclusionTo a degree, the betterment of renal hemodynamics is correlation with the reduction of systemic blood pressure and mechanism of action of antihypertensive agents.
