RESUMO
Objective To investigate the clinical effects of Losartan on hemorrheology and left heart function in essential hypertensive patients.Methods 43 essential hypertensive patients were treated with Losartan,50 ms/d～100 ms/d for twelve to seventeen months.20 essential hypertensive patients were treated with Fu Fang Jiang Ya Pian as control group.Then the changes of hemorrheology indexes and left heart function were tested in both groups.Results After the treatment with Losartan the blood pressure reduced effectively(P＜0.001),the whole blood low shear rate hyperviacoSity(ηb),plasma viscosity,AI,whole blood low shear rate reduced viscosity,erythrocyte electrophoresis,Fib reduced obviously(P＜0.01),but the control group had not statistical significance(P＞0.05)before and after treatment.The whole blood high shear rate hyperviscesity,whole blood high shear rate reduced viscosity,Hct,RRI reduced too(P＞0.05),but there was no statistical significance.LVM(P＜0.01)and LVMI(P＜0.05)were obviously reduced,E/A was increased(P＜0.01),IRT(P＜0.05)was shorten (P＜0.05),while the cardiac diastole function improved effectively.The significant differences were not observed in the control group pre and pest treatment(P＞0.05).Condusion Losartan can effectively reduce blood pressure.At the same time,it improves RBC deformation capability,reduce erythrecyte aggregation,Fib,Hct of essential hypertensive patients,and reduce blood viscosity.Losartan can also reduce myocardial hypertrophy,heart weight,and improve heart function.
