    Statin treatment, applied before percutaneous coronary intervention (PCI), was shown to reduce periprocedural myocardial damage and overall MACE. ( 1 ) Most of the studies showing such relation were done in statin naďve patients. In the only study that was done in statin treated patients, overall population did not reach proposed LDL target i.e. < 1.8 mmol/L. Reaching that target is a measure of adequate statin treatment in everyday practice. We hypothesized that achieving LDL target, i.e. applying adequate statin treatment, could reduce periprocedural myonecrosis in patients with stabile coronary disease scheduled for elective PCI. Data from 372 patients, in a period of 16 months, were collected. Values of troponin I were measured before the procedure as well as 8 and 16 hours after the procedure. Lipid parameters were determined before the procedure. Intensity of periprocedural myonecrosis was measured as a difference between troponin I values before the procedure and the values 8 and 16 hours after the procedure. Statin reload was not applied. In patients reaching LDL target (114 patients) intensity of periprocedural myonecrosis was lower both at 8 hours (p=0,038) as well as at 16 hours (p=0,013) after the procedure when compared to patients that did not reach LDL (258 patients) target. When statin naďve patients were excluded from the analysis the same difference, between patients reaching LDL target (104 patients) and those that did not reach it (204 patients) both at 8 hours (p=0,028) as well as at 16 hours (p=0,003) after the procedure, could be observed. In a multiple regression analysis only LDL levels significantly (p=0,003) correlated with intensity of periprocedural damage. No such correlation was found for other lipid parameters, CRP or creatinine. Our results show that reaching LDL target reduces myocardial damage during PCI. Such a relation could imply a need for a more stringent adherence to LDL target in patients undergoing elective PCI procedures.
