Adverse reactions.

BackgroundAlthough the current guideline recommends the use of high-intensity statin to reduce the low-density lipoprotein cholesterol (LDL-C) level by 50% in patients with baseline value of ≥ 190 mg/dL, direct application of this recommendation to Asian populations is still questionable. This study was performed to investigate the statin response of LDL-C in Korean patients with LDL-C ≥ 190 mg/dL.MethodsA total of 1,075 Korean patients (age 60.7 ± 12.2 years, women 68%) with baseline LDL-C ≥ 190 mg/dL without cardiovascular disease was retrospectively reviewed. Lipid profiles at 6 months, side effects and clinical outcomes during the follow-up period after statin treatment were assessed according to statin intensity.ResultsMost of the patients (76.3%) were treated with moderate-intensity statins, 11.4% with high-intensity statins, and 12.3% with a statin + ezetimibe. The reductions in LDL-C percentage at 6 months were 48.0%, 56.0% and 53.3% in patients treated with moderate-intensity statins, high-intensity statins and statin + ezetimibe, respectively (P P = 0.024). During the median follow-duration of 815 days (interquartile range, 408–1,361 days), the incidences of cardiovascular events were not different among the 3 groups (log-rank P = 0.823).ConclusionsCompared to high-intensity statin, moderate-intensity statin was effective enough in reaching target goal of LDL-C without increase in cardiovascular risk and with fewer side effects in Korean patients with LDL-C ≥ 190 mg/dL.
