The use of excimer laser atherectomy (ELA) has significantly evolved from the mid-1990s to the present, showing substantial improvements in both coronary and peripheral artery interventions. Initially associated with suboptimal outcomes due to low-en...

Background: Sortilin (SORT1), linked to the 1p13.3 coronary risk locus, is implicated in lipid trafficking and atherogenesis; however, clinical studies of circulating SORT1 have produced inconsistent results. We evaluated whether circulating SORT1 is...

Background: Atrial fibrillation (AF) is frequently encountered in patients presenting with acute coronary syndrome (ACS); however, its clinical significance beyond being a simple rhythm disturbance remains debated. We hypothesized that AF at presenta...

Background: Spontaneous recanalized coronary thrombus (SRCT) is an uncommon and often underrecognized coronary pathology that may be angiographically subtle despite having functional significance. Optical coherence tomography (OCT) enables accurate d...

Artificial intelligence-based quantitative coronary angiography (AI-QCA) has recently emerged as a promising tool for real-time lesion assessment in cardiology. We aimed to validate a novel AI-QCA software, trained on a Korean dataset, in a European...

Background: Cancer and cardiovascular disease are the two leading causes of death in Canada. Although treatments have improved tremendously across the years, interventions such as radiotherapy and chemotherapies are known to have negative impacts on...

Background and Aim: New-onset atrial fibrillation (NOAF) is a common condition in critically ill patients, yet the evidence on optimal NOAF management and outcomes is limited. This study evaluates the impact of management strategies on short- and lon...

Background: Myocarditis is a potentially life-threatening inflammation of the myocardium that can be triggered by viral infections, including influenza. While corticosteroids have historically been used with caution in viral myocarditis due to concer...

Cardiac disturbances are well-recognized in traumatic brain injury (TBI), but most involve supraventricular arrhythmias or repolarization abnormalities, while sinus arrest is rarely reported. We present a case of a 37-year-old man who developed recur...

Because CKMS was only proposed by the American Heart Association in 2023, there has been a paucity of information about the distribution and determinants of the syndrome across population groups. We reviewed published studies of the prevalence of CKM...
