F. Garmendia et al., Attaining United States and European guideline LDL-cholesterol levels withsimvastatin in patients with coronary heart disease (the GOALLS study), CURR MED R, 16(3), 2000, pp. 208-219
The effectiveness and safety of simvastatin in reducing low-density lipopro
tein cholesterol (LDL-C) to target levels in patients with coronary heart d
isease (CHD) were evaluated in the GOALLS (Getting to Appropriate LDL-C Lev
els with Simvastatin) study. This multinational, multicentre, prospective,
open-label, study consisted of a six-week diet washout period followed by a
14-week titrate-to-goal treatment period with simvastatin. One hundred and
ninety-eight men and women with documented CHD and a fasting LDL-C level b
etween 115 mg/dl (3.0 mmol/l) and 180 mg/dl (4.7 mmol/l) and triglycerides
(TGs) less than or equal to 400 mg/dl (4.4 mmol/l) were enrolled. The patie
nts were started on 20 mg simvastatin with dose titration up to 80 mg if th
e LDL-C remained above 100 mg/dl at weeks 6 and 10. The key efficacy parame
ters were the percentage of patients achieving US and European LDL-C goals
[less than or equal to 100 mg/dl (2.6 mmol/l) and less than or equal to 115
mg/dl (3.0 mmol/l), respectively]. Safety was evaluated by monitoring labo
ratory tests and recording adverse events.
After 14 weeks of simvastatin (20-80 mg) treatment, approximately 90% of th
e patients achieved LDL-C goals according to US(87%) and European (94%) gui
delines. Most patients (72-93%) achieved target LDL-C levels on 20 Mg simva
statin. An estimated 14% of the patients required titration to the 80 mg do
se. Treatment with simvastatin (20-80 mg) produced statistically significan
t improvements in all measured lipid variables by the end of the study. The
mean reductions in total cholesterol and LDL-C, and the median reduction i
n TG, were 28%, 41% and 16%, respectively. The increase in high-density lip
oprotein cholesterol and apolipoprotein A-1 were 5% and 4%, respectively. S
imvastatin was well tolerated across the dosage range.
In conclusion, simvastatin, 20-80 mg/day, was safe and highly effective at
reducing LDL-C levels. The recommended US and European LDL-C treatment goal
s were achieved in approximately 90% of the patients. These goals were simi
larly achieved for a variety of high-risk sub-groups (hypertensives, diabet
ics and elderly patients).
