The RED-LIP study--pravastatin in primary isolated hypercholesterolemia--an open, prospective, multicenter trial.
The therapeutic effects of the HMG-CoA reductase inhibitor pravastatin on plasma lipids were assessed in an open, prospective, multicenter trial over a treatment period of 3 months. Of a total of 1111 patients, the overall results were calculated from 715 evaluable patients (352 men and 363 women, mean age: 56.1 +/- 11.3 years) with primary isolated hypercholesterolemia (hyperlipoproteinemia type IIa according to Fredrickson) being at high risk for cardiovascular disease according to the classification of the national cholesterol consensus, whose guidelines are distinguishing between three risk levels (low, moderate, and high, respectively) of total-cholesterol (total-c) as well as LDL-c. The treatment period was preceded by a 3-month dietary counselling phase. Treatment with pravastatin significantly reduced total-c (23.8%, p < 0.001), LDL-c (31.9%, p < 0.001) and triglyceride (16.9%, p < 0.001) levels, concomitantly those of HDL-c were significantly raised (15%, p < 0.001). Pravastatin lowered the total-c/HDL-c ratio by nearly 36% from a mean of 8.1 +/- 2.5 to a mean of 5.2 +/- 1.6. At the end 476 patients (66.6%) received the standard dosage of 10 mg/day whereas 140 patients (19.6%) were recorded to take a dose of 20 mg/day. When comparing those patients (n = 456) having maintained consistently a dose of 10 mg pravastatin per day from week 0 to week 12 with patients (n = 113) who received 20 mg/day from week 4 to 12 similar efficacy was observed in both groups (reduction of total-c: 24.5% vs. 22.2%, n.s., reduction of LDL-c: 33.0% vs. 30.0%, n.s.).(ABSTRACT TRUNCATED AT 250 WORDS)
