Article Abstract
Neoatherosclerosis (NA) is a significant contributor to late stent failure; however, predictors of late in-stent restenosis (ISR) with NA have not been systematically reported. This study aimed to identify predictors of NA incidence and plaque vulnerability in patients with late ISR and the role of low-density lipoprotein cholesterol (LDL-C) levels in this process. A total of 216 patients with 216 lesions who underwent optical coherence tomography (OCT) before interventional procedure for late drug-eluting stent ISR were enrolled and divided into NA and non-NA groups based on OCT findings. Results showed that higher LDL-C levels were associated with NA, thin-cap fibroatheroma (TCFA), intimal disruption, plaque erosion, and thrombosis. Multivariate regression analysis revealed that the LDL-C level was an independent risk factor for NA and TCFA. The LDL-C levels exhibited a significant predictive value for NA and TCFA, surpassing other factors such as stent age and other lipid types. In conclusion, a high LDL-C level is an independent predictor of NA incidence and plaque vulnerability in patients with late ISR.

Introduction: Cigarette smoking is a well-recognized independent risk factor for numerous cardiovascular disorders and contributes to the increasing morbidity and mortality associated with chronic heart diseases (CHD). This study aimed to evaluate how cigarette smoking affects lipid metabolism and inflammatory processes, along with other related mechanisms, in order to better understand the potential cardiovascular risks faced by smokers.
Objectives: To evaluate and compare the serum lipid profile and high-sensitivity C-reactive protein levels between cigarette smokers and non-smokers.
Prevalence and penetrance of pathogenic and likely pathogenic and gene variants linked to familial hypercholesterolemia and increased risk of ischemic heart disease.

Background: Familial hypercholesterolemia (FH) is a prevalent hereditary disorder, with its monogenic form linked to an elevated risk of early-onset ischemic heart disease. Evaluating the prevalence and penetrance of pathogenic and likely pathogenic variants associated with this disorder would provide valuable information supporting routine FH screening of the general population. Such informed screening would facilitate early identification of at-risk individuals, enabling timely intervention and management.

Background: Statin therapy lowers the risk of major adverse cardiovascular events (MACE) among people with HIV (PWH). Residual risk pathways contributing to excess MACE beyond low-density lipoprotein cholesterol (LDL-C) are not well understood. Our objective was to evaluate the association of statin responsive and other inflammatory and metabolic pathways to MACE in the Randomized Trial to Prevent Vascular Events in HIV (REPRIEVE).

Elevated levels of low-density lipoprotein cholesterol (LDL-C) are a key risk factor contributing to the progression of ischemic heart disease. Inhibition of proprotein convertase subtilisin/kexin type 9 (PCSK9) with small interfering RNA (siRNA) provides an alternative therapeutic option for lowering LDL-C levels. However, the poor pharmacokinetic profiles of naked siRNA hinder clinical application.
