Risk factors in elderly patients selected by primary care physicians for hypolipemic treatment
1996
PURPOSE: To evaluate the influence of age on response to pravastatin treatment in patients treated by community physicians. METHODS: According to age, 873 patients were divided in three groups: group A with ages ranging from 45 to 59 years (n = 55), group B with ages from 60 to 64 years (n = 182) and group C with ages from 65 to 70 years (n = 143). After four weeks only with diet orientation, patients received 10 mg/day of pravastatin for 12 weeks. RESULTS: There was a greater prevalence of risk factors in elderly patients: hypertension (45.7%, 54.4% and 57.1% in groups A, B and C respectively p = 0.0165), diabetes mellitus (9.3%, 17.6% and 25.8% respectively in groups A, B and C p < 0.0001), and previous heart disease (23.1%, 34.3% and 34.7% in groups A, B and C respectively p < 0.001). During the period of diet orientation there was a similar total cholesterol reduction in the three groups (about 10.5%), the reduction reached 30.0% with the introduction of pravastatin for 12 weeks. Low density cholesterol level decreased during the diet period in the three groups (about 10.5%), pravastatin prescription induced further reduction (about 31.7%). The high density cholesterol level (HDL) increased significantly with pravastatin treatment (12.7%). After pravastatin treatment the increase in HDL levels was more significantly among those patients with initial low levels of HDL (< 35 mg/dL) in the three groups. CONCLUSION: In patients selected by community physicians to receive lipid lowering therapy, increased age was associated with greater prevalence of risk factors and heart disease. Regardless of age, there was a good response to pravastatin treatment, however less than half of patients had received treatment prior to the protocol.
