Background: Non-bacterial thrombotic endocarditis (NBTE) represents a manifestation of thrombotic endocarditis characterized by the formation of thrombus on the heart valve leaflet. While neurological events are the most frequent initial presentation of NBTE, myocardial infarction also stands out as a major clinical manifestation among NBTE patients.

Case Summary: A 61-year-old female with no history of cardiovascular disease or episodes of chest pain suffered a left main trunk ST-segment elevation myocardial infarction (STEMI) after craniotomy for the treatment of oligodendroglioma.

Aims: More than one-third of type 2 long QT syndrome (LQT2) patients carry KCNH2 non-missense variants that can result in haploinsufficiency (HI), leading to mechanistic loss-of-function. However, their clinical phenotypes have not been fully investigated. The remaining two-thirds of patients harbour missense variants, and past studies uncovered that most of these variants cause trafficking deficiency, resulting in different functional changes: either HI or dominant-negative (DN) effects.

Introduction: Radiation-induced carotid artery stenosis (RI-CS) is known as one of long-term side effects of radiotherapy for head and neck cancer (HNC). However, the clinical time course after irradiation has been poorly understood. We aimed to investigate the natural history of radiation-induced carotid atherosclerosis, comparing the patients who received radiotherapy for HNC with the patients who were treated without radiotherapy.

Background: Diabetes is a well-known risk factor for adverse outcomes after coronary revascularization.

Objectives: This study sought to determine high-risk subgroups in whom the excess risks of diabetes relative to nondiabetes are particularly prominent and thus may benefit from more aggressive interventions.

Methods: The study population consisted of 39,427 patients (diabetes: n = 15,561; nondiabetes: n = 23,866) who underwent first percutaneous coronary intervention (n = 33,144) or coronary artery bypass graft (n = 6,283) in the pooled CREDO-Kyoto PCI/CABG (Coronary Revascularization Demonstrating Outcome Study in Kyoto Percutaneous Coronary Intervention/Coronary Artery Bypass Graft) registry.

Background: There are limited data on the long-term stent-related adverse events as related to the duration of dual antiplatelet therapy (DAPT) in second-generation (G2) drug-eluting stents (DES) compared with first-generation (G1) DES.

Objectives: This study sought to compare the long-term stent-related outcomes of G2-DES with those of G1-DES.

Methods: The study group consisted of 15,009 patients who underwent their first coronary revascularization with DES from the CREDO-Kyoto PCI/CABG (Coronary Revascularization Demonstrating Outcome Study in Kyoto Percutaneous Coronary Intervention/Coronary Artery Bypass Grafting) Registry Cohort-2 (first-generation drug-eluting stent [G1-DES] period; n = 5,382) and Cohort-3 (second-generation drug eluting stent [G2-DES] period; n = 9,627).

Article Synopsis
  • Higher levels of growth differentiation factor 15 (GDF-15) are linked to increased rates of cardiovascular death and hospitalization for heart failure across various types of atherosclerotic cardiovascular disease (ASCVD).
  • In a meta-analysis involving over 53,000 patients, GDF-15 was shown to have significant prognostic value for major cardiovascular events, particularly in stabilized patients after acute coronary syndrome (ACS) and those with stable ASCVD.
  • While GDF-15 can predict risks for myocardial infarction and stroke, this association is not evident in patients experiencing acute coronary syndrome, suggesting its limitations in acute settings.

Renal involvement is underestimated as an extramuscular manifestation of dermatomyositis (DM). Here, we describe a 67-year-old woman with anti-glycyl-transfer ribonucleic acid synthetase (anti-EJ) antibody and anti-ribonucleoprotein antibody-positive DM complicated by systemic sclerosis, who developed nephrotic syndrome concurrently with the exacerbation of DM, as indicated by incremental serum creatine kinase levels, high-intensity lesions on muscle magnetic resonance imaging, and active interstitial pneumonitis on chest computed tomography. Renal biopsy revealed the presence of immune-deposition in the glomerulus by immunofluorescence.

Article Synopsis
  • - The study compares the long-term outcomes of percutaneous coronary intervention (PCI) using new-generation drug-eluting stents (DES) and coronary artery bypass grafting (CABG) in 2,464 patients with multi-vessel coronary artery disease.
  • - Although the 5-year risk of combined events like death, heart attack, or stroke was not significantly different between the two groups, adjusted analysis showed that PCI had a higher risk of myocardial infarction and the need for additional revascularization compared to CABG.
  • - The findings suggest that while both procedures have similar outcomes regarding death and stroke, PCI with new-generation DES may carry a greater long-term risk for major cardiovascular issues in patients requiring complex multi-vessel treatments

Background: Discordance between patient global assessment (PGA) and physician global assessment (PhGA) of rheumatoid arthritis (RA) disease activity is mainly determined by pain and functional disabilities. This study aimed to investigate the shift in PGA-PhGA discordance and the variables associated with future positive discordance (PGA > PhGA) based on the NinJa database in Japan.

Methods: We examined 7557 adults with RA registered in both NinJa 2014 and 2018, with a discordance cutoff of 3 on a 10-cm scale.

Despite some negative reports regarding the need for the self-monitoring of blood glucose (SMBG), including the issue of cost-effectiveness, there are still many users, and in diabetes treatment, which is largely dependent on the patient's self-care, SMBG remains an important tool in establishing such self-care habits, with several reports supporting this notion. In addition, devices are needed to assist in SMBG for patients with diabetes who have difficulty performing SMBG, such as the elderly or those with visual impairment. In current diabetes care, it is reported that patient-centered care that respects the preferences, needs, and values of individual patients and personalized care that consider the characteristics and comorbidities of each patient are important.

We investigated the relationship between distal interphalangeal (DIP) joint involvement and disease activity in 10,038 patients with adult-onset rheumatoid arthritis (RA). The affected joint distribution was investigated using the joint indices (JI) , , and , corresponding to the upper and lower joints, and the predominance of large-joint involvement, respectively. DIP joint involvement (defined by the presence of tenderness and/or swelling in DIP joints) was present in 206 (2.

Introduction: It is extremely important for patients with diabetes undergoing maintenance hemodialysis (MHD) to receive regular ophthalmologic examinations. However, even in the field of MHD in Japan, where there are many hemodialysis patients and the survival rate is said to be one of the highest in the world, we often see patients with diabetes who do not receive regular ophthalmologic examinations. In this study, we surveyed the status of ophthalmology consultations and the use of diabetic eye notebook (DEN) among hemodialysis patients with diabetes at hemodialysis clinics to confirm the current situation, with the aim of confirming the effectiveness of education on consultation behavior by medical care staff.

Anti-melanoma differentiation-associated gene 5 (MDA5) antibody, a dermatomyositis (DM)-specific antibody, is strongly associated with interstitial lung disease (ILD). Patients with idiopathic inflammatory myopathy (IIM) who are anti-MDA5 antibody positive [anti-MDA5 (+)] often experience chest symptoms during the active disease phase. These symptoms are primarily explained by respiratory failure; nevertheless, cardiac involvement can also be symptomatic.

Recently, one observational study showed that patients with ST-segment elevation myocardial infarction (STEMI) without standard cardiovascular risk factors were associated with increased mortality compared with patients with risk factors. This unexpected result should be evaluated in other populations including those with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and chronic coronary syndrome (CCS). Among 30,098 consecutive patients undergoing first coronary revascularization in the CREDO-Kyoto PCI/CABG (Coronary Revascularization Demonstrating Outcome Study in Kyoto Percutaneous Coronary Intervention/Coronary Artery Bypass Grafting) registry cohort-2 and 3, we compared clinical characteristics and outcomes between patients with and without risk factors stratified by their presentation (STEMI n = 8,312, NSTE-ACS n = 3,386, and CCS n = 18,400).

Article Synopsis
  • - The study compared causes of death in non-ST-segment-elevation myocardial infarction (NSTEMI) and ST-segment elevation myocardial infarction (STEMI) patients, involving over 6,000 heart attack cases.
  • - Results showed no significant difference in overall mortality risk between NSTEMI and STEMI patients both within and after 6 months of their incident, although specific causes of death varied between the two groups during the first 6 months.
  • - The findings suggest that while NSTEMI patients had more deaths from heart failure and post resuscitation status shortly after a heart attack, the long-term risk of death was similar for both types of patients.

There is a scarcity of data on ischemic and bleeding events in patients who experienced major bleeding after percutaneous coronary intervention (PCI). Moreover, there also is a shortage of data on comparative outcomes between patients with and without interruption of an antithrombotic drug after major bleeding. We evaluated the incidence and prognostic impacts of ischemic (myocardial infarction or ischemic stroke) and bleeding (Bleeding Academic Research Consortium type 3 or 5) events after major bleeding in 12,691 consecutive patients who underwent first PCI in the Coronary Revascularization Demonstrating Outcome Study in Kyoto PCI registry cohort-3.

Article Synopsis
  • The study evaluated how heart failure affects long-term outcomes after two types of heart surgery: percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG).
  • Among 3,380 patients with significant coronary artery disease, those with heart failure showed a higher mortality risk after PCI compared to CABG, highlighting the importance of heart failure status in surgical decision-making.
  • The findings suggest that patients with heart failure may have worse outcomes with PCI, while patients without heart failure have similar risks from both procedures.
