Spontaneous coronary artery dissection, which causes acute coronary syndrome and can result in sudden death, is rare; but its true incidence is underestimated, since most patients die suddenly, without diagnosis. The aim of this study was to show the importance of prompt diagnosis and treatment. In reviewing the records of 5,000 consecutive patients who underwent coronary angiography between January 2001 and August 2006, we found 6 cases of spontaneous coronary artery dissection (an incidence rate of 0.12%). Five patients presented with left main coronary artery dissection and 1 patient, with right coronary artery dissection. Angioplasty with stenting failed in the patient with right coronary artery dissection. Coronary artery bypass surgery was performed in all patients. The patient with right coronary artery dissection died of sepsis on the 30th postoperative day. The other 5 patients (83.3%) are still free of symptoms, and they had negative results on stress tests at the 6- and 12-month follow-up visits after coronary artery bypass surgery. The clinical presentation of spontaneous left main coronary artery dissection was similar to that of atherosclerotic disease. However, early diagnosis of spontaneous coronary artery dissection by means of coronary angiography is of paramount importance, because urgent coronary artery bypass grafting can be lifesaving.

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.
