Abstract: ObjectiveTo observe the effect of nitrates and statins on blood pressure,serum lipid and artery structure of elderly patients with isolated systolic hypertension(ISH) and hyperlipidemia.Methods96 elderly patients with ISH and hyperlipidemia were randomly divided into the isosorbide mononitrate triple therapy group(group A),simvastatinelderly two drugs combination group(group B) and control group(group C) with 32 cases in each group.The group A was given isosorbide mononitrate,simvastatinelderly and felodipine.The group B was given simvastatinelderly and felodipine.The group C was given felodipine alone.The whole course lasted 12 weeks and the blood pressure,serum lipid and the change of artery structure were observed.ResultsThe effect of group A was significantly better than groups B and C(P<0.01). The effect of lowering serum lipid and change of artery intima-media thickness(IMT) in groups A and B were better than that in group C(P<0.05).ConclusionNitrates can decrease systolic blood pressure and pulse pressure,but has less effect on diastolic blood pressure.Statins can decrease IMT of the common arteries.The combination of nitrates and statins is speculated beneficial to elderly with ISH.
