Background: The association between lipoprotein(a) [Lp(a)] levels and progression of non-culprit atherosclerosis (NSA) in patients with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI) is unknown.
Methods: This study enrolled 177 patients with ACS who underwent OCT-guided PCI and follow-up OCT examinations of non-culprit lesions between 2013 and 2018. Lesion characteristics including fibrous tissue, calcium, lipid, and macrophage content were assessed using quantitative plaque analysis.
Rotational atherectomy (RA) is an effective, mature, and specific treatment for calcified lesions. However, the incidence of RA-related myocardial injury remains high and has not been adequately addressed. To assess the safety and efficacy of low-temperature RA-flush solution versus room-temperature RA-flush solution during RA.

Trimethylamine N-oxide (TMAO), a metabolite, is a co-metabolite produced by both gut microbiota and livers, originating from foods rich in choline or carnitine. Emerging evidence suggests that TMAO may play a role in the pathogenesis of various kidney diseases, including acute kidney injury and chronic kidney disease. Research has demonstrated that heightened levels of TMAO are correlated with a heightened likelihood of kidney disease advancement and cardiovascular incidents among individuals with chronic kidney disease.

The purpose of the study was to investigate the long-term outcome of 1-year subclinical DES-EE (sDES-EE), which was defined as any reduction in the minimal lumen area (MLA) at stent edge without any evidence of clinical ischemia. A total of 252 patients were enrolled from one of our previous randomized controlled studies, who were detected by optical coherence tomography (OCT) immediately after DES implantation and 1 year later.
View Article and Find Full Text PDFBackground: Although optical coherence tomography (OCT) guidance with the 'MLDMAX' criteria is very useful for de-novo lesions during percutaneous coronary intervention (PCI), there are limited studies on its benefits in patients with in-stent restenosis (ISR). This study aimed to compare the clinical outcomes of patients with ISR who underwent repeat PCI (re-PCI) with OCT or angiographic guidance.
Methods: This retrospective study enrolled 2142 patients with ISR who underwent re-PCI at Nanjing First Hospital from January 2016 to January 2023.
Objectives: To investigate whether negative remodeling (NR) detected by intravascular ultrasound (IVUS) of the side branch ostium (SBO) would affect in-stent neointimal hyperplasia (NIH) at the one-year follow-up and the clinical outcome of target lesion failure (TLF) at the long-term follow-up for patients with left main bifurcation (LMb) lesions treated with a two-stent strategy.
Methods: A total of 328 patients with de novo true complex LMb lesions who underwent a 2-stent strategy of percutaneous coronary intervention (PCI) treatment guided by IVUS were enrolled in this study. We divided the study into two phases.
Background: It is currently uncertain whether the combination of a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor and high-intensity statin treatment can effectively reduce cardiovascular events in patients with acute coronary syndrome (ACS) who have undergone percutaneous coronary intervention (PCI) for culprit lesions.
Methods: This study protocol describes a double-blind, randomized, placebo-controlled, multicenter study aiming to investigate the efficacy and safety of combining a PCSK9 inhibitor with high-intensity statin therapy in patients with ACS following PCI. A total of 1,212 patients with ACS and multiple lesions will be enrolled and randomly assigned to receive either PCSK9 inhibitor plus high-intensity statin therapy or high-intensity statin monotherapy.
Introduction: The natural outcome of coronary plaque in acute coronary syndrome (ACS) patients with chronic kidney disease (CKD) is unique, which can be analyzed quantitatively by optical flow ratio (OFR) software.
Methods: A total of 184 ACS patients with at least one nonculprit subclinical atherosclerosis (NSA) detected by optical coherence tomography (OCT) at baseline and 1-year follow-up were divided into non-CKD group (n = 106, estimated glomerular filtration rate (eGFR)> 90 mL/(min×1.73 m2)) and mild CKD group (n = 78, 60≤eGFR<90 mL/(min×1.
Although patients are undergoing similar lipid-lowering therapy (LLT) with statins, the outcomes of coronary plaque in diabetic mellitus (DM) and non-DM patients are different. Clinical data of 239 patients in this observational study with acute coronary syndrome was from our previous randomized trial were analyzed at 3 years, and 114 of them underwent OCT detection at baseline and the 1-year follow-up were re-anlayzed by a novel artificial intelligence imaging software for nonculprit subclinical atherosclerosis (nCSA). Normalized total atheroma volume changes (ΔTAVn) of nCSA were the primary endpoint.

To explore the potential significance of the reverberation of calcification by comparing both intravascular ultrasound (IVUS) and optical coherence tomography (OCT) measurement post manual coregistration. The reverberation phenomenon is often detected by IVUS for severe calcified lesions post rotational atherectomy (RA), which is thought to be due to the glassy and smooth inner surfaces of calcifications. Because of the poor penetration of IVUS, it is impossible to measure the thickness of calcifications, and the relationship between multiple reverberations and the thickness of calcification lesions has not been reported before.

Methods: The primary endpoints were changes in percent atheroma volume (ΔPAV), normalized total atheroma volume (ΔTAVn) and each component in nonculprit subclinical atherosclerosis from baseline to 1 year measured by optical flow ratio (OFR) software. LR or LP was defined by an increase or decrease in PAV.
In the present study, we aimed to evaluate the cardioprotective effect of neoandrographolide (Neo) on myocardial ischemia/reperfusion injury (I/R) models and explore its possible mechanism. We randomly and equally divided male mice into sham-operation, I/R, and I/R + Neo groups. H9C2 cell line and primary neonatal rat cardiomyocytes were induced into the simulated I/R's status and used to further validate the Neo's role in vitro.

Quantitative flow ratio (QFR) is a method based on the three-dimensional quantitative coronary angiography and contrast flow velocity during coronary angiography (CAG), obviating the need for an invasive fractional flow reserve procedural. This study aimed to assess the serial angiographic changes of de novo lesions post-DCB therapy and further explore the cut-off values of lesion and vessel QFR, which predict vessel restenosis (diameter stenosis [DS] ≥50%) at mid-term follow-up.

Background: Acute coronary syndromes mainly result from abrupt thrombotic occlusion caused by atherosclerotic vulnerable plaques (VPs) that suddenly rupture or erosion. Fibrous cap thickness (FCT) is a major determinant of the propensity of a VP to rupture and is recognized as a key factor. The intensive use of statins is known to have the ability to increase FCT; however, there is a risk of additional adverse effects.

There are limited data on rotational atherectomy (RA) via transradial access (TRA) in this setting. The aim of this study was to evaluate in-hospital and 1-year outcomes in elderly patients with SCCL who underwent RA via TRA.
