Abstract

Background/Aims
To date, prospective data are limited on efficacy and safety profiles of statin therapy in Korean hypercholesterolemic patients. Hence, the aim of this study was to evaluate the practice patterns of statin therapy and its efficacy and safety through the prospective Daegu and Gyeongbuk statin registry.
Methods
Statin naïve patients who were prescribed statins according to the criteria of Korean Guidelines for Management of Dyslipidemia were enrolled. Clinical and laboratory evaluations were performed at baseline and at week 8, where the efficacy was assessed with the same guidelines.
Results
Of 908 patients, atorvastatin and rosuvastatin were most frequently prescribed statins (63.1% and 29.3%, respectively). High intensity statins (atorvastatin 40 mg or rosuvastatin 20 mg) were prescribed in 24.7% of all patients and in 79.5% of high and very high risk groups. The total and low density lipoprotein (LDL) cholesterol levels decreased from 203.7 ± 43.0 to 140.6 ± 28.6 mg/dL and 134.4 ± 35.7 to 79.5 ± 21.3 mg/dL, respectively. The achievement rate of the LDL target goal was 98.6% in low risk, 95.0% in moderate risk, 88.1% in high risk, and 42.1% in very high risk patients (59.7% in overall). There was no significant difference in the efficacy between atorvastatin and rosuvastatin. Adverse events were observed in 12.0% of patients and led to 1.4% of treatment cessation.
Conclusions
The efficacy of the usual starting dose of statins in daily practice was relatively insufficient for Korean hypercholesterolemic patients with high or very high risks. Short-term adverse events of statin therapy were not common in Korean patients with a low discontinuation rate.
