Objective The primary objective was to evaluate the effect of statin therapy/lipid lowering therapy (LLT) on lipid profile, in adults presenting with first acute coronary event. Methods and material A multicentre, observational, prospective cohort study of lipid profiles pre- and post-statin therapy/LLT, among adult patients with confirmed diagnosis of first acute coronary event. The primary outcome measures were low-density lipoprotein cholesterol (LDL-C) in mg/dl, high-density lipoprotein cholesterol (HDL-C) in mg/dl and triglycerides (TG) in mg/dl at baseline and end of study (EOS, 12 weeks [mean: 13.5 weeks]). Results Totally 474 patients completed the study. Number of patients with any LDL-C abnormality (LDL-C [all; LDL was abnormal, either alone or along with other lipid parameter(s)]) decreased from 118 (24.9%) to 27 (5.7%), and for LDL-C (only; only the LDL was abnormal), from 46 (9.7%) to 13 (2.7%), both from baseline to EOS. Of 118 patients with high LDL-C (all) at baseline, 91 (77.1%) had reduction in LDL-C to <100 mg/dl, of which 54 (45.8%) had LDL-C <70 mg/dl at EOS. The patients with LDL-C fraction abnormalities decreased, while HDL-C abnormalities increased at EOS from baseline. No major difference was observed at baseline and EOS in levels of TG (all [TG was abnormal, either alone or along with other lipid parameter(s)]) and TG (only [only the TG was abnormal]). Six (1.3%) had seven serious adverse events. Conclusions Though statin therapy is effective in lowering LDL-C, there still remains residual dyslipidemia, which probably should be tackled with therapeutic and non-therapeutic options.
