Guedeney P, et al. - In this single-center study of 2,653 patients who underwent elective percutaneous coronary intervention (PCI) between January 2010 and May 2016, researchers assessed how well patients adhered to guideline-recommended statin therapy (GRST) and the rate of residual cholesterol risk (RCR) at follow-up following elective PCI. High-intensity statin (HIS) therapy for patients ≤75 years old and moderate-intensity statin (MIS) or HIS therapy for patients > 75 years was the definition of GRST. The definition of RCR at follow-up was <50% reduction in low-density lipoprotein cholesterol (LDL-C) with HIS or <30% with MIS for statin-naïve patients and LDL-C >70mg/dL for nonstatin-naïve patients. Female gender, previous myocardial, smoking, and higher LDL-C level at baseline were risk factors of RCR at follow-up. In patients who underwent elective PCI, a significantly improved rate of GRST at discharge has been reported over time but no appreciable change has been reported for the prevalence of RCR at follow-up. Based on these findings, it could be justifiable to further implement guidelines as well as novel or more intensive pharmacotherapy.
