Aims: Apolipoprotein CIII (ApoCIII) has a variety of proatherogenic properties. Given that hyperglycemia induces ApoCIII transcription, this apolipoprotein may promote coronary atherosclerosis in type 2 diabetic patients. We aimed to elucidate whether ApoCIII affects plaque progression and instability in statin-treated type 2 diabetic patients.
View Article and Find Full Text PDFBackground: Type 2 diabetic patients exhibited an increased secretion of triglyceride-rich lipoproteins and low high-density lipoprotein cholesterol levels with a greater amount of small dense low-density lipoprotein (LDL). Given that apolipoprotein B (apoB), a proatherogenic lipoprotein, exists at both triglyceride-rich lipoproteins and LDL particles, circulating apoB may associate with diabetic coronary atherosclerosis.
Methods: The OPTIMAL study was a prospective randomized-controlled study which employed serial near-infrared spectroscopy (NIRS)/intravascular ultrasound (IVUS) imaging to evaluate the efficacy of glycemic control on coronary atherosclerosis in 94 statin-treated type 2 diabetic patients with coronary artery disease (CAD) (UMIN000036721).
Background: Immunoglobulin G4-related disease (IgG4-RD) is a systemic immune-mediated inflammatory disease that infrequently involves the coronary arteries. Given that pericoronary adipose tissue (PCAT) attenuation reflects the degree of inflammation in the coronary arteries, monitoring inflammation with PCAT may enable evaluation of disease activity in IgG4-related coronary periarteritis (CP).
Case Summary: A 58-year-old man with a history of IgG4-RD presented with ST-segment elevation myocardial infarction.
Directional Coronary Atherectomy (DCA) is a potential treatment option for left main (LM) bifurcation lesions, as it may prevent side branch occlusion and reduce the need for complex stenting. Recent studies have suggested that combining drug-coated balloon (DCB) with DCA can lead to favorable cardiovascular outcomes. However, the comparative efficacy of DCB and current drug-eluting stents (DES) following DCA for LM bifurcation lesions remains unclear.

The impact of evolocumab in patients with varying lipoprotein(a) [Lp(a)] levels is unknown.
Methods And Results: Serial optical coherence tomography imaging was performed to evaluate changes in plaque composition in response to treatment with evolocumab 420 mg or placebo for 50 weeks.

Aims: Lipoprotein(a) (Lp[a]) exhibits atherogenic and thrombogenic properties. We investigated the association between Lp(a) levels and the risk of coronary heart disease (CHD) and stroke.
Methods: We used data from 5138 people ≥ 30 years old registered in the Suita Study, a Japanese population-based prospective cohort study.
Background: Idiopathic pericarditis generally has a favorable prognosis, but contemporary data on treatment patterns and outcomes remain limited.
Methods And Results: Using a nationwide Japanese database, we analyzed 8,020 pericarditis patients hospitalized between April 2016 and March 2021, and identified 3,963 (49%) patients with idiopathic pericarditis after excluding those with infectious, autoimmune or other causes. During the study period, the median age increased from 62 to 68 years (P<0.

With the increasing number of transcatheter aortic valve replacements (TAVR) performed annually, coronary cannulation in post-TAVR patients has gained importance. The aim of this study was to investigate the effectiveness of the en face view for post-TAVR coronary cannulation. Between March 2015 and March 2024, we evaluated coronary cannulation based on the period when the en face view was initiated post-TAVR in December 2021.

Objectives: Postinfarction left ventricular free-wall rupture (LVFWR) is a rare, unpredictable and often fatal complication of acute myocardial infarction. We reviewed our surgical experience with postinfarction LVFWR over 25 years to identify risk factors for in-hospital mortality.
Methods: Seventy-two consecutive patients with LVFWR who underwent surgical repair between 1994 and 2023 were retrospectively analysed.
Background And Aims: Addition of the PCSK9 inhibitor, evolocumab, to statin therapy promoted coronary plaque stabilization after an acute coronary syndrome. While apolipoprotein B (ApoB) has been proposed as a goal for lipid-lowering therapy in the prevention of cardiovascular disease, its association with plaque stability has not been studied.
Methods: The High-Resolution Assessment of Coronary Plaques in a Global Evolocumab Randomized Study (HUYGENS) used serial optical coherence tomography to assess coronary plaque phenotypes in patients with non-ST elevation myocardial infarction treated with evolocumab plus statin or placebo plus statin for 52 weeks.
Background: The ongoing residual cardiovascular risks despite lowering low-density lipoprotein cholesterol (LDL-C) levels suggest the need to identify additional drivers associated with atherosclerosis. Circulating lipoprotein(a) [Lp(a)] promotes formation of foam cells via its proatherogenic properties. However, whether a lower Lp(a) level in combination with favorable LDL-C control could induce a more stable form of disease remains unknown.

However, RV dysfunction occurs in the late phase of heart failure, when it may not respond to interventions. The pulsatile component of RV afterload, pulmonary artery (PA) compliance, is a sensitive parameter that decreases before RV dysfunction occurs.

The severity of calcification increases the risk of future target lesion revascularization (TLR). This study was conducted to determine whether calcification severity in the adjacent zone is associated with TLR.

We investigated the association between the NP-cGMP cascade and left ventricular reverse remodelling (LVRR) in anterior AMI.
Methods: 67 patients with their first anterior AMI (median age, 64 years; male, 76%) underwent prospective evaluation of plasma concentrations of the molecular forms of A-type and B-type natriuretic peptide (BNP) and cGMP from immediately after primary percutaneous coronary intervention (PPCI) to 10 months post-AMI.
Background: The Society of Cardiovascular Angiography and Intervention (SCAI) has defined 5 stages of cardiogenic shock (CS). In patients with acute myocardial infarction (AMI) who initially present in stable hemodynamic condition (SCAI CS stage: A or B), CS stages could deteriorate despite therapeutic management. However, deterioration of SCAI CS stages after AMI remains to be fully characterized.

Background: Calcified nodule (CN) is a phenotypic feature of calcified plaques which causes acute coronary syndrome (ACS). Recent studies reported that culprit lesions harboring CN has been shown to increase a risk of repeat revascularization after percutaneous coronary intervention (PCI) with the implantation of newer-generation drug-eluting stent (DES) or debulking device. Mechanistically, a re-protrusion of CN into the lumen has been considered as an important cause associated with repeat revascularization after PCI.

Background: Cardiovascular events still occur at intermediate stenosis with fractional flow reserve (FFR) ≥0.81, underscoring the additional measure to evaluate this residual risk. A reduction in distal coronary artery pressure/aortic pressure (Pd/Pa) from baseline to hyperemia (ie, change in Pd/Pa) reflects lipidic burden within vessel walls.

Background: The atherogenic characteristics of heterozygous familial hypercholesterolemia (HeFH) increase the risk of premature atherosclerotic cardiovascular disease including not only coronary artery disease but ischemic stroke. Asymptomatic intracranial artery stenosis/occlusion (IASO) is a major cause of ischemic stroke, but it has not yet been fully characterized in patients with HeFH.
Methods And Results: This study analyzed 147 clinically diagnosed subjects with HeFH who underwent magnetic resonance imaging/magnetic resonance angiography imaging for evaluation of IASO (≥50% diameter stenosis).

While technological advances have made implants a good treatment option with a good long-term prognosis, peri-implantitis, which results in alveolar bone resorption around implants, has been observed in some cases. Micromotion at the implant abutment connection can cause peri-implantitis. However, the temporal progression of micromotion upon loading remains unclear.
