Effect of pharmacologic lipid lowering on health-related quality of life in older persons: results from the Cholesterol Reduction in Seniors Program (CRISP) Pilot Study.
OBJECTIVE
To determine the effect of lovastatin therapy on health-related quality of life in older persons.


METHODS
A prospective, randomized, double blind clinical trial.


METHODS
Four university medical center research clinics.


METHODS
There were 431 men and women, primarily 65 years of age or older, with low density lipoprotein levels greater than 159 mg/dL and less than 221 mg/dL. Exclusion criteria included a Mini-Mental state score less than 24 or presence of recent cardiovascular events or other serious chronic disease likely to shorten survival.


METHODS
All participants were administered the National Cholesterol Education Program step one diet and were then randomized to placebo, 20 mg lovastatin, or 40 mg lovastatin.


METHODS
Areas of health-related quality of life assessed in the Cholesterol Reduction in Seniors Program (CRISP) included: (1) physical functioning, (2) sleep behavior, (3) social support, (4) depression, (5) cognitive function, and (6) health perception. Three global change questions asked the patients to judge change in general health since starting the study diet or the study medication and change in ability to function or care for self. Although some patients were followed for a total of 12 months, all participants were followed for 6 months, and 6-month data have been used for the primary analysis in this paper.


RESULTS
Patients treated with 20 mg of lovastatin had a 17% and 24% reduction in total cholesterol and LDL-cholesterol, respectively. Patients treated with the 40-mg lovastatin dose achieved reductions of 20% for total cholesterol and 28% for LDL-cholesterol. Complaints of possible adverse events were remarkably similar in the two active treatment groups and the placebo group. At 6 months of follow-up there were no statistically significant differences found in mean change scores from baseline between treatment groups on the health-related quality of life measures (physical functioning, sleep, social support, depression, cognitive function scales, health perception) or global questions.


CONCLUSIONS
This study demonstrates that lovastatin was extremely well tolerated in an older cohort, both with regard to symptoms and to health-related quality of life.
