Background: In an aging society, percutaneous coronary intervention (PCI) for super-elderly patients is commonly performed in clinical practice. However, data are scarce regarding the clinical features and outcomes of this population.
Methods: This multicenter observational study enrolled patients aged over 90 years who underwent PCI across 10 hospitals between 2011 and 2020.
Article Synopsis
- A study examined the clinical characteristics and future cardiac event risks of young females (under 60) undergoing percutaneous coronary intervention (PCI), revealing limited existing data on this demographic.
- Among 187 participants, almost half had diabetes, and 20.3% exhibited renal dysfunction.
- Findings indicated that renal dysfunction and multivessel disease were significant predictors of serious cardiac events, with patients experiencing renal issues facing a threefold increased risk.
Article Synopsis
- * A study analyzed 132 patients with acute total/subtotal ULMCA occlusion who underwent emergency procedures, revealing that those with a dominant RCA experienced significantly lower all-cause mortality compared to non-dominant RCA patients.
- * The research suggests that having a dominant RCA could be a positive factor in long-term survival for patients treated for ULMCA occlusion, emphasizing the need for more attention to coronary dominance in such cases.
Despite the excellent long-term results of internal mammary artery (IMA)-left anterior descending (LAD) bypass, percutaneous revascularization of IMA is sometimes required for IMA-LAD bypass failure. However, its clinical outcomes have not been fully elucidated. The aim of this study was to investigate the long-term clinical outcomes, including target lesion revascularization (TLR) following contemporary percutaneous revascularization of failed IMA bypass graft.

During the COVID-19 pandemic, the rate of hospital admissions has been lower and the rate of in-hospital mortality has been higher in patients with acute coronary syndrome (ACS) in Western countries. However, in Japan, it is unknown whether the COVID-19 pandemic has affected the incidence of ACS.

Methods and results: From a multi-center registry, 134 patients due to acute total/subtotal occlusion of the unprotected LMCA were reviewed. Emergency room (ER) status classification was defined according to the presence of cardiogenic shock and cardiopulmonary arrest (CPA) in the ER (class 1=no cardiogenic shock; class 2= cardiogenic shock but not CPA; and class 3=CPA).
Background: Spontaneous coronary artery dissection (SCAD) has recently been recognized as a cause of acute coronary syndrome (ACS), especially in young women. However, the characteristics, optimal treatment, and prognosis of patients who experience SCAD have not been fully described.
Methods: Data were retrospectively collected from a multicenter registry.
Background And Objectives: The left ventricular (LV) stimulation site is currently recommended to position the lead at the lateral wall. However, little is known as to whether right ventricular (RV) lead positioning is also important for cardiac resynchronization therapy. This study compared the acute hemodynamic response to biventricular pacing (BiV) at two different RV stimulation sites: RV high septum (RVHS) and RV apex (RVA).

There have been no reports concerning postexercise systolic blood pressure (SBP) response in patients with ultrasound echocardiographic (UCG) LV hypertrophy and CAD.
Methods: Sixty-six patients with both UCG-LV hypertrophy (LV mass index 134 g/m2 or greater for men or 110 g/m2 or greater for women) and positive ST depression of at least 0.
Introduction: Transient T wave changes after cessation of preexcitation have been attributed to cardiac memory. However, there have been no reports on the effects of long-term cardiac memory on repolarization dispersion before and after catheter ablation in patients with Wolff-Parkinson-White (WPW) syndrome.
Methods And Results: We investigated 47 patients with an accessory pathway (AP; 24 manifest left-sided, 14 manifest right-sided, and 9 concealed left-sided).
