Introduction: Current European guidelines recommend treatment with lipid-lowering therapy (LLT) to a low-density lipoprotein cholesterol (LDL-C) target of < 70 mg/dl for patients at very high risk. LDL-C target attainment and use of LLTs in these patients in Greece is not known.
Material and methods: The Dyslipidemia International Study (DYSIS) II was a multicenter observational study. The coronary heart disease (CHD) cohort was divided into two groups based on treatment status (on LLT for ≥ 3 months or not on LLT). The acute coronary syndrome (ACS) cohort was evaluated at the time of admission and again 120 ±15 days after admission.
Results: In the CHD cohort (n = 499), 457 (91.6%) patients were on LLT. The LDL-C target value was attained by 26.5% of LLT users. Statin monotherapy was used by 77.5% of treated patients, with a mean ± SD atorvastatin dose equivalent of 24 ±16 mg/day. In the ACS cohort (n = 200), 159 (79.5%) patients were on LLT at admission. Mean ± SD LDL-C levels were 108 ±40 mg/dl at admission and 86 ±25 mg/dl at follow-up. LDL-C target value attainment rates were 16.2% at admission and 25.0% at follow-up. At admission, statin monotherapy was used by 86.8% of treated patients. The mean ± SD atorvastatin dose equivalent increased from 20 ±14 mg/day at admission to 29 ±15 mg/day at follow-up. The statin dose was associated with higher odds of LDL-C target value attainment (OR = 1.05, 95% CI: 1.02-1.08).
Conclusions: The LDL-C target attainment by very high risk patients in Greece is suboptimal. Increasing the statin dose or combining it with non-statins may improve target value attainment.
