Objectives: This study sought to determine the absolute and relative associations of diabetes mellitus (DM) and hemoglobin A (HbA) with sudden and/or arrhythmic death (SAD) versus other modes of death in patients with coronary artery disease (CAD) who do not qualify for implantable cardioverter-defibrillators.
Background: Patients with CAD and DM are at elevated risk for SAD; however, it is unclear whether these patients would benefit from implantable cardioverter-defibrillators given competing causes of death and/or whether HbA might augment SAD risk stratification.
Methods: In the PRE-DETERMINE study of 5,764 patients with CAD with left ventricular ejection fraction (LVEF) of >30% to 35%, competing risk analyses were used to compare the absolute and relative risks of SAD versus non-SAD by DM status and HbA level and to identify risk factors for SAD among 1,782 patients with DM.
Results: Over a median follow-up of 6.8 years, DM and HbA were significantly associated with SAD and non-SAD (P < 0.05 for all comparisons); however, the cumulative incidence of non-SAD (19.2%; 95% CI: 17.3%-21.2%) was almost 4 times higher than SAD (4.8%; 95% CI: 3.8%-5.9%) in DM patients. A similar pattern of absolute risk was observed across categories of HbA. In analyses limited to patients with DM, HbA was not associated with SAD, whereas low LVEF, atrial fibrillation, and electrocardiogram measurements were associated with higher SAD risk.
Conclusions: In patients with CAD and LVEF of >30% to 35%, patients with DM and/or elevated HbA are at much higher absolute risk of dying from non-SAD than SAD. Clinical risk markers, and not HbA, were associated with SAD risk in patients with DM. (PRE-DETERMINE: Biologic Markers and MRI SCD Cohort Study; NCT01114269).

Background: Upfront 2-stent techniques are often used in bifurcation percutaneous coronary interventions (PCI), but there is controversy about optimal strategy selection.
Methods: The authors examined the clinical and angiographic characteristics and long-term outcomes of 232 bifurcation PCIs that were performed using the double kissing (DK) crush or culotte technique in 216 patients between 2014 and 2023 using data from the Prospective Global Registry for the Study of Bifurcation Lesion Interventions (NCT05100992). The inverse probability of treatment weighted (IPTW) Cox proportional hazards model was used to assess long-term outcomes.

Background: The use of the Ostial Flash balloon (Ostial Corporation) has received limited study in aorto-ostial chronic total occlusion (CTO) percutaneous coronary artery intervention (PCI).
Methods: The authors evaluated the outcomes of Ostial Flash balloon use in a large CTO-PCI registry (PROGRESS-CTO, NCT02061436).
Results: The Ostial Flash balloon was used in 54 of 907 aorto-ostial CTO PCIs in 905 patients (6.

Importance: The integration of patient-reported outcome (PRO) assessments in cardiovascular care has encountered considerable obstacles despite their established clinical relevance.
Objective: To assess the impact of a physician- and patient-friendly electronic PRO (ePRO) monitoring system on the quality of cardiovascular care in clinical practice.
Design, Setting, And Participants: This open-label, multicenter, pilot randomized clinical trial was phase 2 of a multiphase study that was conducted from October 2022 to October 2023 and focused on the implementation and evaluation of an ePRO monitoring system in outpatient clinics in Japan.

Myocardial infarction (MI) is a coronary artery-related disease that seriously threatens human life and is the leading cause of sudden death worldwide, where a lack of nutrients and oxygen leads to an inflammatory response and death of cardiomyocytes. Ferroptosis is a form of non-apoptotic cell death associated with metabolic dysfunction, resulting in abnormal breakdown of glutamine and iron-dependent accumulation of reactive oxygen species (ROS) during metabolism. However, the molecular mechanism of ferroptosis in the pathogenesis of MI and the function of Klotho and KRAS on ferroptosis during MI remain unclear.
